Tech Tip Tuesday

Ultralight.

Or so I hope.

As you know, we've been looking at ways to make a 15' long canoe and forms levitate. Well, OK - I'd like it to levitate, but physics and gravity have intervened. Here is what we have done so far to make things a bit lighter.

We cut out material from the plywood forms in areas where it wasn't necessary. We limited the amount of material we took off to try to keep from having thin sections that would warp. This is what one of the patterns looks like after being "lightened":


We weighed the pieces that we cut out of all of the patterns for this canoe. It amounted to 14.5 pounds of material that were removed. Quite a substantial savings!

We're also shifting from a strongback made from dimensional lumber to one made with a combination of sheet goods and small amounts of dimensional lumber. The picture below shows the sample beam that was made up earlier. I haven't weighed it yet, but by just picking it up, I know it is lighter than our older designs.


The picture below shows the beam from the bottom. It is a 1/2" thick plywood deck with 1/4" luan sides and 2x6" blocking. It is a remarkably rigid structure. The sides are glued and screwed to the plywood and blocking.


A quick view of the barn where the boats are all stored for the moment. It may look like a bit of chaos, but we know where everything is!

Fall Arrived


It seems we went from days in the 70's to frost at night and highs in the 50's with the blustery Fall wind in no time at all. This past weekend, we went to a local Fall Festival and had a wonderful time. My DW put up a great and detailed post here. I'll be a bit more brief about it but let you enjoy some of the sights of the season.

Harvest decorations in the town hall. This is a small sampling of those to be seen around the building and around the town.


I wish I could share the sounds. The whistling wind and the rattling of blowing leaves, the crisp "crunch" when you step on them.


The smells, too. The faint spice of woodsmoke in the air, fried dough with maple cream (one of my favorite guilty pleasures...)


The feel is unmistakable. A frigid bite in the air and then the feeling of warm sun on you as the clouds passed.


Yup. Looks like Fall is here to stay for a bit.

Somali pirates attack French

military flagship

NAIROBI (AFP) – Somali pirates attempted to storm the French navy's 18,000 tonne flagship in the Indian Ocean after mistaking it for a cargo vessel, the French military said on Wednesday.

The crew of La Somme, a 160-metre (525-foot) command vessel and fuel tanker, easily saw off the brazen night-time assault by lightly armed fighters on two lightweight skiffs and captured five pirates, a spokesman said.

"The pirates, who because of the darkness took the French ship for a commercial vessel, were on board two vessels and opened fire with Kalashnikovs," Admiral Christophe Prazuck said in Paris.

La Somme is the French command vessel in the Indian Ocean, overseeing French air, sea and land forces fighting Somali pirates and hunting terrorists under the banner of the US-led Operation Enduring Freedom.

Officers on the ship have directed commando operations to free French hostages in the hands of Somali pirates.

The pirates tried to flee when they realised their mistake but were pursued by French forces who, after an hour-long chase, caught one of the skiffs, Prazuck said.

On it they found five men but no weapons, water or food as the pirates had apparently thrown all of the boat's contents overboard, the spokesman said.

A Western official at sea in the area, speaking to AFP on condition of anonymity, said that there had been an exchange of fire between the warship and the pirate launches.

"One of the skiffs managed to get away in the night because La Somme was busy with the first pirate boat," he said.

"Despite the arrival of other vessels, they haven't yet managed to find the second boat," he said, adding that many warships in the area were busy hunting another group which attacked a cargo ship off the Seychelles on Sunday.

The world's naval powers have deployed dozens of warships to the lawless waters off Somalia over the past year to curb attacks by pirates in one of the world's busiest maritime trade routes.

La Somme was operating 250 nautical miles (460 kilometres) off the Somali coast, on its way to resupply fuel to frigates patrolling shipping lanes as part of the European Union's Operation Atalanta anti-piracy mission.

This was not the first time that Somali pirates have mistakenly attacked a French naval vessel. Several pirates were captured in May when they attempted to board a frigate in the area.

Somalia has had no proper government since it plunged into lawlessness after President Mohamed Siad Barre was overthrown in 1991.

The country is riven by factional fighting and pirate gangs operate freely from several ports along its Indian Ocean and Gulf of Aden coasts.

According to the environmental watchdog Ecoterra International, at least 163 attacks have been carried out by Somali pirates since the start of 2009 alone, 47 of them successful hijackings.

Last year, more than 130 merchant ships were attacked, an increase of more than 200 percent on 2007, according to the International Maritime Bureau's Piracy Reporting Centre in Kuala Lumpur.

Pirates have in recent weeks resumed attacks with the end of the monsoon season. Last week Somali gunmen captured Spanish fishing boat The Alakrana with 36 crew members in the Indian Ocean.

The US Maritime Administration warned last month that the end of the monsoon season was likely to bring an increase in piracy off Somalia and urged shipping companies to be vigilant.

Calmer waters allow pirates, who often operate in small fibreglass skiffs towed out to sea by captured fishing vessels, to hijack freighters, trawlers and private yachts. Cruise vessels have also been attacked.

(Perhaps it's just me, but attacking a French Navy ship sounds like a really, REALLY bad idea.)

Unintentional Atkins Diet


This morning I get up feeling particularly groggy. The bathroom upstairs is occupied, so rather than have my morning shower first, I go downstairs and proceed to make myself some lunch.

Silverware? Check.
Yogurt? Check.
Soda? Check.
Apple? Check.
Lunch entree? Check.
Ice Pack? Check.

Zzzziiiippp! Done.

I bring my lunch bag and briefcase to the front door and head up for a shower.

Now that lunch-time has arisen at work, I take the container with my lunch in it to warm in the microwave in our cafeteria. Pop it in and hit start. I'm anticipating a nice lunch of rice with peppers, onions, tomatoes and fajita-seasoned chicken with a bit of cheese on top. MMMmm...

Er, what is this?

Dang.

I've taken the two leftover pork chops from the grill the other night instead of my intended lunch. Atkins diet, here I come.

Wordless Wednesday

I couldn't give a rat's ...


Well, actually I can now. After spending the past winter trying to get rodents out of the house (see here and here), we suddenly have invited them in.

A couple who live down the street got a pair of gerbils for their sons. Unfortunately for them, the pair turned out to be a boy gerbil and a girl gerbil. Within short order, they had 13 gerbils. One day I was asked to come down and look at a canoe that they had to put a value on it. DD tagged along and went in to visit the gerbils and decided that we should "help them out" and take a few. I wasn't particularly enthusiastic about the idea and put it off. Granted, they were trying to give them away, but I couldn't really see us having them in the house. I'm not really much of a rodent fan - I'd rather have a more interactive pet (like a cat) and am more of a predator than prey kinda guy. DW is also not a fond fan of animals and wasn't willing to let me bring another cat in the house, so I mentioned the gerbils to her, but didn't think anything would come of it.

I was very surprised about a month and a half later when one of the couple was walking by the house as DW and I were working in the front yard. DW mentioned that we should ask if the gerbils were still available. (Huh?) Yes, they still had gerbils to give away and would we please take some? We said that yes, we'd take two. I went out later that day to a pet supply place for all the requisite rodent supplies and was frankly astonished at how expensive a pair of free gerbils could be. I put the supplies in the playroom and neither DS nor DD took any notice of them until the next morning.

When they finally noticed, they were very, very happy children. We picked the two gerbils up (Scampers, the light colored one and King, the gray one - actually father and son.) the next morning and settled them in.



The hardest part is making sure that the cage is kept clean and that the children are treating them well. It's a bit of a lesson in responsibility for them, but the lesson seems to be absorbed very, very slowly.

By the way - did I mention that gerbils are very fast? It make it very difficult to get a picture of them!

Mid-Atlantic Small Craft Festival


The Mid-Atlantic Small Craft Festival will be held this Saturday from 10:00 AM-5:00 PM at the Chesapeake Bay Maritime Museum in St. Michaels Maryland. This is a unique event as it is focused as it says on small craft - typically about 20' and under for paddle, sail and oar. There is also an emphasis on using these craft - they're not just for static display.

I've missed out on this for the past few years even though I've been in Maryland on the weekend of the festival. I really need to get down to this event.
