Paddling in the off-season.
While I must admit that I'm not usually a fan of plastic canoes and kayaks, they do have their purpose. In particular, for whitewater. Still, some local whitewater paddlers have taken the term "whitewater" to a new extreme:
Check it out!
The best reason for a plastic boat and paddles.

If you can't fix it...
A friend of mine who I've known for quite some time and his wife got me the gift card above as a Christmas present. I must say, they know me pretty well and do a great job with gifts - The one above is no exception. Looking at the gift card and the way it was made, it was difficult for me to tell that it wasn't actually wrapped in duct tape!
On the top of the card was an image of a roll of duct tape and the words, "A true handyman's wrapping paper."

The Amazing SWS(tm) System
These are NOT my presents.
How can you tell?
That's easy. You see at this time of year, all of my wrapping is done by the Amazing SWS(tm) System. It is the only way that I can manage to get all of my wrapping done. So, what is this fantastic system?
It's the Simian Wrapping System(tm) The Simian Wrapping System exists because almost all of my Christmas gifts strangely appear to have been wrapped by monkeys. I try, I really do, to do a neat job wrapping, but somehow the primate in me comes out in my wrapping skills. Perhaps it is because I'm often rushed for time this time of year, but I should really do a better job. Sharp corners? Straight edges? Neatly folded over ends?
Fuhgeddaboutit.

Neither rain, nor sleet nor snow...
Shall keep us from building boats. It may delay us slightly, but we'll still be building boats. Yesterday was supposed to be a "double session" for my canoe building class in which we work all day with a break for lunch and a bit of socializing. This is usually a good thing as we get to have a very productive day as we get to skip one session of moving things in and out of the shop. Unfortunately, as you can see from the picture of the back yard, it snowed rather significantly (about 10" or so) and we decided to just do a single session in the afternoon to allow people to clear driveways and for the roads to be plowed.
(Note the snowy view out the shop window! ) As we were working on the boats one of my students asked why we build them at this time of year. The answer is really simple - would you rather be building canoes when you should be paddling them or when you can't?

Don't do this with your canoe!
Three scout leaders from Cornwall are back home after their canoe was sunk by a hippopotamus in west Africa.
Brian Sheen, 66, Geoff Ryder, 59, and Michael Billworth, 23, had to abandon their dugout canoe after the hippo attacked four days into the trip.
They had to trek through the jungle for five days to reach a small village where they received help.
Mr Sheen said, despite training for the dangers of hippos, nothing could have prepared them for the surprise attack.
The three adventurers had planned to paddle 2,500 miles (4,000km) down the river from Faranah in Guinea to promote the scouting movement.
Mr Sheen said: "We were on full hippo watch and all of a sudden we came to an abrupt halt.
"I thought we had hit a rock. Then the front went up and the middle went up.
"Then the back flew in the air and Geoff, who is 16 stone [102kg], was suddenly airborne and landed in the water beside the boat."
Mr Sheen said there was "not the slightest inkling" that there were hippos about on the stretch of river where they were attacked.
"It burst on us like a submarine-launched missile," he said.
"It happened so quickly we didn't have time to be scared."
After dragging Geoff Ryder back on board, the trio managed to get their semi-submerged boat to a mud bank.
"The canoe was going down fast," said Mr Sheen.
"The hippo was about 20 yards away looking at us."
His concerns were raised when the animal was heard running through the undergrowth nearby.
"We hoped he wouldn't come back for a second bite," said Mr Sheen who was relieved to see the beast heading inland.
The three then ditched most of their gear, apart from satellite navigation systems, and started a trek through head-high elephant grass and bamboo.
It took five days and nights.
"Every few yards there were crevasses where the rainwater had run down to the river.
"We had seen a village before the attack. It was our only hope," said Mr Sheen.
"We were pretty whacked. The temperature was 100F [38C] during the day."
The villagers, who were initially wary, fed the adventurers before giving them all a lift 60 miles (96km) on motorcycles back to Faranah, where they had begun.
The men, who have all returned to Cornwall, now hope to revisit the area next year, but said they would be taking a ferry next time.

Fruitcake
In my household there is a cultural gap regarding Christmas deserts. My DW is from the UK. Traditional Christmas deserts include such things as Christmas puddings (steamed - probably made with real lard!) with brandy butter and little bite-size mince pies. I tend to actually like the Christmas puddings, but never really have been a mince pie fan. These are things that I never really had growing up and were somewhat alien to me. (Ok - a confession, we DID have mince pies at Thanksgiving in my parent's house.) Still, one of the items that exemplifies this gap is fruitcake.
To be honest, I grew up with Figi's fruitcake which to most people resembles a brick. By the time it arrives at the door, it is a dense, nay, solid item that is probably best used as a door stop. It typically arrived as a slightly battered rendition of the image below:
It wasn't until we were about to get married that I got my true introduction to fruitcake. I was told that it was a traditional English wedding cake. I was in shock. I described my experiences with fruitcake to my bride-to-be and she basically laughed at me. Fruitcake? That door-stop brick from Figi's from my youth? The one immortalized in the song yesterday from NPR that had the lyrics : "Denser than a load of barnyard turkeys, Tougher than a truck of old beef jerky..." When I think Fruitcake that's what I think of.
My other half thinks of fruitcake in a different way. She's from the UK and has a fond memories (dare I say a love?) of the stuff. When she proposed fruitcake as our wedding cake, I nearly dropped out of my chair in shock. She was fairly insistent and as she was making most of the arrangments for the reception, what choice did I have?
Then she told me of the preparation.
In detail.
Hmmm.
1. Bake the cake with the dried fruits, etc.
2. Allow to age.
3. Feed it a regular dose of stout and brandy to hydrate the cake. (Ok, at this point I started to get interested..)
4. After the cake can take no more stout and brandy, coat with marzipan and royal icing.
5. Decorate.
6. Serve.
I will admit that once I got a slice of this cake on my wedding day, my attitude towards the stuff was changed. Apparently here in the States we forget steps 3 through 5. The gentleman who made the cake is a chef of the highest order and had done a gorgeous job of decorating (and feeding...) The main body of the cake was decorated with a pastel yellow icing and the tiers were separated with brandy glasses. The decoration on the cake was in pastel pinks and green with hand-made sugar roses that looked like they were freshly picked from the garden.
Now, if I could only get him to make some fruitcake for Christmas dinner!

Tech Tip Tuesday
Two of them are books. One is by Jerry Stelmok and Rollin Thurlow and is called The Wood and Canvas Canoe. Another book is by Jerry Stelmok and is entitled, Building the Maine Guide Canoe. Both titles are widely available from places like the WoodenBoat Store and the Wooden Canoe Heritage Association's (WCHA) online store.
In these books are some places to find materials that you will need for the job. In particular, the canvas, brass tacks, stem band and filler. There is also an excellent list of suppliers over at the WCHA. I would be remiss in not mentioning that WoodenBoat offers an excellent school where you can take classes (see my earlier posts on the topic) and many builders offer both building and restoration instruction at their shops for a fee - very often all you need to do is ask.

We must be nuts...
We feed the birds in the winter and by extension, the squirrels. There really isn't any way to feed birds without feeding every other wee beastie that loves seed in the neighborhood.
I have 6 feeders out at the moment. One is a "squirrel-proof" feeder that has a spring-loaded bar which closes over to dispensing holes when something heavier than a bird lands on it. The squirrels have figured out how to disable the bar by moving the spring. There is also a clear plastic feeder that we usually attach to the kitchen window. This year I (hopefully) got smarter and moved it to a window that the squirrels couldn't reach - until DW showed me a picture of the squirrel walking along the lower part of the window jamb.
We also have 4 other pretty run-of-the-mill feeders. 2 are in the front of the house in a tree and 2 are hung on hooks attached to the deck railing. To be honest, I've been getting my money's worth in bird seed watching the antics of the squirrels try to get food out of the feeders. They are quite the acrobats and can manage to hang onto the feeders with their rear feet while eating upside-down. What is amazing is to watch them go from hanging upside-down to pulling themselves up by their stomach muscles to get another mouthful of seed.
What is really amazing is how bold the squirrels are. Last Christmas, we had one that DS and DD named "Piggy" sit in the clear plastic feeder on the window as we ate breakfast about 3 feet away. We even got pictures with the kids putting their hands on the window with Piggy stuffing herself on the other side of the window.
We've seen Piggy around this year - she's recognizable by the white spot on her side. The kids claim that they can identify the different squirrels and have named some of them as well. Piggy we can tell. There's one black squirrel called "Inky". I'll be darned if I can tell the rest of the gray squirrels apart reliably. Some have more white on the back of the ears or brown on their backs and heads, but I haven't got them sorted out.
They seem to know that as long as we're in the house, we will not bother them. As soon as we open the door, they head for the hills. The kids think they would like to pet a squirrel, but we certainly don't want any pet squirrels!

Stretching Canvas
Before you start, you need to take off the old canvas. This usually involves removing the outwales and removing the tacks hidden beneath that held the canvas in place. You may also have a keel and brass stem-bands to remove. Typically, all of the fasteners are found along the gunwales and from stem to stern at the centerline of the canoe.
Once the canvas is removed, you will want to inspect the woodwork to see if there is rot, cracked planking or ribs, loose tacks or any varnish work that it needs. If there is such damage, now is the time to repair it.
Once any necessary repairs have been made, make sure the outside is smooth and fair and give it a light sanding and a light coat of linseed oil and turpentine. This helps to waterproof and preserve the wood. When done, the boat looks like this:
You should also have your materials collected. You'll need a few specialty items and a few tools.
- Canvas - It should be an appropriate weight for the boat your building - typically #8 -heavy, #10 - Typical or #12 - lightweight and longer than the boat by about a yard or two.
- Brass Tacks - AKA Canoe tacks - in two lengths - 7/8" to 11/16" for the at the ribs and 5/16" or 3/8" for the stems.
- Bedding Compound - a peanut butter consistancy material for the stem ends.
- Filler - a thick paint mixed with or without white lead for "killing the weave" on the canvas. More on this later.
- Brass Stem Band and Screws
- Cardboard
- Prop sticks or weights (sandbags, garden fertilizer, etc.)
- Winch - AKA "come-along"
- Chain and hooks
- C-Clamps
- ~3' Blocks with "key" for clamping canvas as stretched and eye bolts to pull canvas. - one set for each end of the canvas.
- Canvas "clothespin" - a piece of hardwood with a wide kerf cut up the middle (lengthwise) and a bolt to prevent it from splitting at the closed end of the kerf.
- Canvas Stretching Pliers
- Small Hammer
- Razor Knife
- Screwdriver
After cutting the appropriate length of canvas, fold it in half the log way with the opening at the top and clamp both ends with the keyed wooden blocks. The key keeps the canvas from slipping out under tension. The blocks are clamped together using two or three C-clamps. When this is done, pull up the tension on the canvas to make sure there aren't any wrinkles.
Let the tension off and put the boat in the envelope of canvas. Think of it like a hammock for your boat. Be sure it is well seated in the canvas. Pull up on the tension again, but not so much that you rip the canvas or it slips from the clamps. You will then need to either weight the canoe with bags of something heavy or if you have a ceiling overhead, you can use some wood to prop the boat down from the ceiling. The best way is to protect the inside of the boat with cardboard, put a 2x6 in the bottom of the boat and use another piece of lumber to wedge between the 2x6 and the ceiling joist. Install the canvas "clothespins" at either end as close to the stems to hold the canvas near the hull at the ends.
The longer tacks are then put in. There are two at each rib, just below the top edge of the planking. Usually a scrap of wood is used to protect the inwale. You then grab the canvas with the canvas-stretching pliers and rock the handles into the hull on the block of wood. (In the picture below, the pliers are upside down - see the rounded top?) Placing tacks is done by Braille - you need to feel for the rib location and the top of the planking - sometimes you can see the rib through the canvas. You'll want to be about 1/4" down and 1/4" in from the edges so you don't split planking and ribs. If you get the tension correct, there will be little puckers above the tacks. Make sure any wrinkles in the canvas are being moved from the center of the hull towards the stems. Tacking the canvas is most easily accomplished with two people.
Alternate sides to keep the tension on the canvas even. If there are wrinkles, pull up on the canvas a bit harder. As you get close to the ends, you will also find that you need to trim the canvas near the gunwale so that the pliers can "bite" the canvas for a good grip as there will be too much fabric. You will also find you have to pull the canvas towards the stem to get rid of the wrinkles. When you get all of the tacks put in at the gunwale line, you need to make a choice. You can:
A) Simply let down the tension and cut the canvas (vertically) about a foot beyond the end of the stem. The excess canvas helps you to pull the fabric around the stem to finish this area.
OR
B) Roll a scrap of canvas to be a small "sausage" about 5 layers thick an inch wide and about 4' long (depends on stem length) and staple parallel to the stem through the "sausage" and the canvas into the planking and stem on both sides of both stems from deck to keel. Then cut down the hull as above. You will need to work any wrinkles out as you staple this in place.
The advantage of B is that as you're tacking the stems in place, there is not tension. This is an advantage if you are working alone.
Put the canoe upside down on a pair of saw horses and remove the clamps.
Before you tack the stem slit the canvas down the middle of the envelope. You start this cut at the keel where the fabric would overlap. Put one tack in the stem just above the slit. Then, apply a thin and even layer of bedding compound over the stem and pull the canvas off "normal" to the stem so you get no wrinkles. Starting at the keel and heading towards the deck tack every 3/4" or so. It should look like the the picture below. The wrinkle to the right of the stem shouldn't be there...
Trim the excess canvas close to the stem on the that hasn't been tacked. Apply bedding compund again and repeat in the other direction. Trim the excess canvas again and repeat for the other end of the boat:
The next step is to apply the filler to the canvas. The filler is a tough, abrasion-resistant coating that fills the weave of the cloth and effectively waterproofs the boat. There are leaded and unleaded fillers. I personally prefer the leaded filler for the anti-microbial properties of the white lead. If you avoid contact with the lead, you should do OK. I think it's nice to label the inside of the boat somehow to let a future restorer know that they are dealing with lead... The leaded and unleade filler apply almost the same way, but the leaded tends to inhibit mildew in the canvas for many, many years.
It's applied by brushing on with a heavy brush and then rubbing in with a canvas mitt. (Wear latex or nitrile gloves underneath if it's leaded filler!) It may take several coats. You'll know when to rub with the glove when it rubs smoothly and leaves you with a slate-like finish.
Whe the filler is applied, it will take a few months (yes months - 2-3!) for the filler to cure or "polymerize". When cured, you can sand (wear a mask!) and apply primer and paint - usually a porch and floor enamel and re-install keel, stem band and outwales.
Happy Paddling!

Fungus Tour of Central Vermont.
As the weather has proceeded to get colder, I was rooting around looking at some pictures stored on my computer. My family went on a camping trip to central Vermont this summer, and I was looking over pictures from the trip and enjoying the thoughts of the warm weather that we enjoyed.
Suddenly, as I looked at the pictures more closely, I was reminded that not only was it much warmer this summer, it was also much wetter as well.
How so?
Well, it seems as though every third picture was of some type of mushroom. That isn't to say that they weren't photogenic mushrooms, tho'.

Tech Tip Tuesday
- no stems
- only an inner stem
- a combination of inner and outer stems
Some builders try to save weight by building a canoe without any stems at all. Gil Gilpatrick follows this building method. As a Maine Guide, he uses canoes that he's built using this method for his guiding business. Considering the abuse that these boats take, this method must be strong enough.
This method depends on the fiberglass coating to provide the strength that you need in the ends of the canoe. As you are building the canoe, the strips meet at the ends and one strip is beveled and the other passes by. The strips are glued together to hold the shape of the canoe until the builder can fair and glass the hull. This method requires glassing the hull inside and out. Glassing up in the ends is difficult and messy.
Other than the glassing, I have some concerns about keeping the hull together during the building process. There just isn't a lot of area for the glue where the strips meet in the ends. Also, the fiberglass and epoxy is flexible. If you have an impact, the fiberglass and epoxy flexes and the soft cedar underneath will crush. The fiberglass and epoxy usually recovers, but the wood fibers do not, leaving a delaminated area where the 'glass and epoxy aren't in contact any more.
Oh yeah. Did I mention that it is difficult and messy to glass up inside the stem? (Yeah, I meant to repeat that...)
One Stem
It's also possible to build with only an inner stem. The inner stem provides a larger bonding surface for the glue than strips alone. It is more rugged than without, but takes a bit more time and effort. To save weight on the small canoes my students build, I recommend softwood for the inner stem - usually poplar or basswood. On small canoes, we do not glass over the stem, but cut the fiberglass about an inch away from the stem and paint the wood with epoxy to seal it. The same delamination issue from impact still remains as you don't have an outer stem.
Inner and Outer Stem
This is my preferred method. I use the same softwood inner stem mentioned above, and either a softwood or hardwood outer stem. I feel that this provides a much nicer cosmetic appearance. Also with a hardwood outer stem, the crushing issue from impact is much less of a problem. The choices of hardwood let you choose from different colors to give many different cosmetic appearances.
In addition, there are several areas along the stem where beginners can have difficulty getting good joints. The stems cover these areas and provide a bit of camoflauge for the bad joints while also giving a pleasing appearance, cosmetically.
Building Stems
If you are lucky enough to have some unique pieces of wood that have a curve matching that of your stem (crooks or knees...) You can saw the stems out of solid stock.
Most of us aren't that lucky.
Another way to deal with the issue is to steam bend the stems. This isn't a bad or difficult method, really, but steam-bending is a subject unto itself. When Jerry Stelmok bent stems for his canoes, they were symmetrical, so he bent them out of one wider piece of stock and cut them in half with a table-saw. (This was done to avoid twisting of the stems.) The one thing to keep in mind is that steam-bent stems have a tendency to relax, so it's best to keep them clamped in place until ready to use.
The way I teach my students to make stems is to laminate them from thin strips of stock. First, I cut thin strips that will bend around the forms without breaking. As I cut the strips, I keep them in the same order that they come off the board. I want to laminate them this way. There is a reason - when it comes to bevelling the strip later, keeping the grain direction constant makes the cutting easier as the grain doesn't change directions and tear out. Here is a pack of strips fanned out:
The stem patterns are covered with a layer of tape so that the stems will not be bonded to the forms.
The strips are then bonded together. We usually use wood glue as the stem will be coated with epoxy. You can use polyurethane adhesives, but epoxies would be overkill.
Starting at one end the strips are clamped to the pattern. (there are holes in the pattern to make this possible) I usually use spring-jaw clamps to keep the strips from sliding side-to-side when slippery with glue. You want to be careful to make sure that the stem isn't twisted.
As I've said before - you can never be too rich, too good looking or have too many clamps.
Once the glue has set, the stem can be removed and will hold the shape once removed from the pattern.
In a later post, we'll talk about trimming the stems and bevelling them.

BRRRIIINNNNGGGG!!!
As the party DW and I held at the house was winding down, and we were all relaxing in the living room. Somehow, we got onto the topic of "Yip Yips". (Don't ask me how we got there...) Yip Yips were characters created for Sesame Street by Jim Henson and his crew. Growing up, most, if not all of us, were brought up watching the Muppets and they weave their way through our consciousness in strange ways. Anyway, here is a picture of the Yip Yips below:
At the party, one friend had his iPhone with him and after the topic was broached, he brought up a few videos of the Yip Yips from YouTube. As I went looking tonight, I found this:
Anyhow - that's the diversion that my brain took tonight - where did yours go?

Tales from Cuboria...
Some people in this world are just destined to have a job where you get to say, "Do you want fries with that?" Some of those people work for one of our vendors, a national office supply company that shall be nameless....
We're working on a long-standing project that is a departure for us in terms of manufacturing methods and packaging. It's both a cool and very complex device, which after long hours of hard work, has nearly come together. Sadly for us, one of the last bits of detail, labels for the outside of the device and a switch panel just couldn't come together in the required amount of time. I was assigned the task of creating substitutes for these labels and the switch panel. The vendor who will be making these items sent me the artwork they are using for the panels. I took the artwork and went to my local vendor on Thursday afternoon to see what they could do to help.
What they had was an amazing color printer that prints with solid inks on fairly heavy card-stock. I got a sample and found out what I needed to supply for file types, sizes and that I could submit my documents online to save myself a trip. I went back to my office to figure out how I could make this work. After some looking around, I discovered that we have some adhesive films and plastic sheets for the outer layer and I resolved to laminate some labels and cut them out by hand. No big deal, I thought - maybe about a 4 hour job for all that this entailed.
Wrong.
On Friday morning, I tried to email the files that I had received to their print center only to be told by their web page, that this was not possible.
Okay. Nothing is insurmountable.
I drove down with a thumb-drive loaded with the images that I needed to have printed. I figured on about 5 copies of each to give me a chance to try things out and make mistakes. This was a total of 25 pages of printing. I brought black-and-white full size copies of the images with me to the store along with a specific set of instructions:
5 copies of each file
Color print onto heavy, matte finish card stock
Print all images full size
Simple, right?
"I'll have those ready for you by 5:00 PM tonight, sir - 8:00 PM at the latest."
"Well, we're under some pressure here - can you expedite the order?"
"I'll see what I can do. We'll call you at 5:00 or sooner to let you know how things are going and we'll call if we have any questions."
"Great."
5:00 PM came and went. No phone call. 5:15 came. I called them to enquire how the print job was going.
"We're just about to start it - why don't you stop by about 6:30?"
( #$(%*$!!! ) "Sure. See you then."
I killed some time running some errands and arrived at the store to find the print job done. Still, it wasn't quite right. Two of the labels were much too small. I pointed the fact out to the woman working at the counter and she re-printed them in the correct size while I waited. On the surface, the others appeared to be correct. I finally left the vendor's store at about 7:10 PM on a Friday evening when I'd really rather be at home with my family.
This morning (Monday), I arrived at work and started to assemble the labels.
*Uh oh...* Yup. They're a little small...
I return to the vendor's store with the files and tell the woman at the counter (A different person than the one I dealt with on Friday) that the files weren't properly printed and pointed out the clear instructions on the envelope the labels were given to me in. She told me that she'd fix that - no charge. (Darn tootin'!) After a few minutes, she prints two pages. They're exactly the same as the one I have. She spends another few minutes looking through options for the printer, looking confused. She finally calls me over behind the counter and tells me that she can't figure out what the problem is. She selects her way through print options including "FIT TO PRINTER MARGINS" and hits "PRINT". A warning screen comes up that reads, "OUTPUT WILL NOT BE FULL SCALE" and she clicks "OK"!!!
ARRRRGGGGHHHH!!!
She passes me the mouse and I manage to turn the scale to "NONE" and print, getting full scale prints of my labels. (I hope) It's not every day that the customer has to come in and show the employees how to operate their equipment!
Some days, you just can't win.
Oh, and one parting shot - just remember that Murphy was an optimist!
Images from Despair.com Go look at their demotivators. You'll laugh yourself silly.

With a resounding *THUD!*
Fall has fallen around here. The change has been both sudden and cruel. Temperatures have dropped nearly 30 degrees.
It had been fairly warm around here until about a week ago. Nice mild temperatures and all. I spent the past few weekends around the house preparing for fall by bringing in the deck furniture, cleaning the windows and pulling in the screens, shutting off the outside water faucets, the sprinkler system and cleaning up the garden beds and leaves. Unfortunately, this cleanup has prevented me from getting in some of my favorite paddling which is fall paddling.
Paddling in the fall has some risks with the cooler water and air temperatures that you have to keep in mind and be prepared for, but if you are, it's really wonderful. I've been paddling when it was cold enough to have a skim of ice on the water under the shade of the pine trees where we put in.
Fall paddling is above all things, quiet. There are very few people out on the water - you usually have the place to yourself. The foliage is out and if you are in the sun on a still day, it is warm. The mosquitoes have vanished for the season and most of the pond weed has died back. Migrating birds and ducks will be your companions.
One of my favorite places is actually a small meandering stream that is there as a result of the beavers building a dam at the bottom of what once was essentially a marsh. The marsh is in a valley that is sheltered from the winds. While not a long paddle - you can maybe go in about 3/4 of a mile or so, it is a pleasant trip with abundant wildlife. The paddling is on a narrow twisting waterway with water that is full of tannins. The dark tannin stained waters provide from some great reflections of the foliage in the water.
Do you have a favorite place and time of year to paddle?

Ooops....
Every so often when you are building a boat, you have a problem. It may be a little mistake, it may be a big mistake. At this point, you need to use your judgement to decide what you want to do.
Do you:
- Ignore the problem?
- Try to camoflage (HIDE!) the problem?
- Repair the problem?
- Start again?
The problems that aren't critical, but as the builder, tend to irritate you, you can try to camoflage. In strip construction, this tends to be minor holes or cracks that you'll fill with "Boat Spackle" - AKA "Dookie Shmutz" - a mixture of epoxy, wood flour and fumed silica...
Sometimes it's possible to repair the problem - either by replacing or patching the damaged area, or usually re-setting the strip while the glue is still wet. You can even remove epoxy (with a little heat) if you royally mess it up.
Occasionally, you have a problem where you need to start again. You're building a seat and you crack a rail while putting in a mortise and have concerns about the strength of the stock. You're making a strongback and it is warped beyond repair. You're cutting strips and they are too thin. You're molding stock with cove-and-bead and it just isn't right. These are the things where it's just not salvageable. The finished product will be ugly or will not work right. Sometimes it's not worth continuing to put more effort and money into the boat.
This week one of my student's box-beam for a strongback got wet by sitting on wet lumber. It was warped fairly badly. We have some potential methods to solve the issue, but we're waiting to see how bad the warp is after the beam dries. We're still early enough in the process to make another box-beam - it will take time and money to do so if necesary, but it is better than continuing to throw time and money at a boat that will have a tendency to turn to one side or the other.
The wisdom to know which path to take is called experience.
Just remember - good judgement is the result of experience and experience is the result of bad judgement.
