The Expedition Wherry Hull is Formed

Big changes since my last post... the hull of the Expedition Wherry is now wired together and the epoxying has begun.

I'm doing things a bit differently from the manual, or at least I'm adding some things that the manual doesn't mention. So if you're following along and mine looks different than what the manual shows, you'll know why.

Since my last post I have scarfed the sheer clamps together and then epoxied them to the #3 panels at the sheer line. I think I used around 80 clamps!

The manual suggests that you overlap the transom ends and then later cut the sheer clamps short, but if you read further in the manual it mentions that you can do that now. I did it now and found that it worked better. I drew a line and used my pull saw to cut the ends.

Then I set up the frames that the hull would be sitting on while the stitching was going on. I snapped a chalk line down the center of my table. Then I drew lines perpendicularly down from the centers of the frames. Finally, I mounted the frames on the center line.

Then I wired on the panels. Here's how it looks after several hours of wiring.

This was after the first two panels were added.

Then I added the #3 panels with the sheer clamps. The transom went on much easier than I expected.

I had to drill holes into the sides of the transom doubler to hold the tops in.

One thing I'm a bit surprised about in the manual is the lack of specific ideas and steps on certain things. I already mentioned that CLC doesn't really give very detailed instructions on fiberglassing (more on that in future posts too). But here's an idea that is commonly used in other stitch and glue boats, and that is to use large push-pins to hold panels flush to each other.

If a panel just won't stay flush, you simply move the panel out or in and then push a push-pin into the edge of the panel to hold it either out or in. In the picture below, it looks like the pin isn't doing much, but if I pulled it out, the bottom panel would pop out further than the #2 panel. Cool idea, huh?! Why doesn't CLC mention that for their first-time builders?

CLC also suggests that you mix up a large batch of thickened epoxy and add huge fillets along all the seams. I'm only doing just enough to hold the hull together. Then tomorrow I will flip the boat over and run epoxy along the outside seams. This will hold the entire hull together and I won't have the thickened epoxy seams to look at. Structurally, it shouldn't be an issue because it will really be the 6 oz. fiberglass cloth inside and out that really holds the panels together. And this will look much nicer!

More later!

Aloha!

The Rogue Manual

I've posted about this earlier, but thought it might be good to post it again for anyone who may be interested. I've started to write a manual of tips and tricks for Pygmy solo kayak builders. It covers the taping method, so that your boat doesn't have hundreds of holes all over it. I'm on version 2 now. Version 2 covers several other tips and tricks from myself and from others as collected over time. ATTENTION : Use the manual at your own risk! The only person responsible for any mistakes or problems with the building of your boat is you. Always use the official Pygmy manual that came with your kit. Only do those tips and tricks that make sense to you. If something in the manual doesn't sound right to you, then don't do it! Neither I, nor Pygmy Boats, nor anyone else except YOU is responsible for the safety of your boat and the quality of your build. It's in very rough draft form right now, but if you'd like to read it, please send a $10 donat...

Annapolis Wherry Hull Painted

If you haven't yet, please read my previous post regarding amine blush and primers. After thoroughly washing the hull with water, and then priming, I was now ready for top coating. I used Interlux Toplac Plus in Matterhorn White. What a great paint! OMG... this stuff seems to have magical properties! I've never used a paint that does not sag or run, even on vertical hull sides. Of course, you have to roll on a light coat with a foam roller, but even with a thin coat like that, most paints would still have runs. This one doesn't! And you don't need to tip it either! Just roll it on and walk away. It gets better too... you don't have to sand after each coat! As long as you roll on a second coat after 16 hours but before 3 days, you don't have to sand. Nice! I did three coats in three days with no sanding between coats. There's a slight bit of orange peel, but most of the surface issues are due to my poor surface prep instead of orange peel. To be honest, ...

Waterlog Surfboard Build, Part 2

Since my last post I've made a lot of progress. I've completed the rails and the landing strips. Here is the chine log being epoxied in. By the way, I'm using epoxy for much of this. I ended up using Titebond III for most of the rails because they didn't have a lot of force on them and I could get them clamped down quickly (Titebond III sets quickly). But for anything that has any stress on it, I'm using WEST System epoxy that I have left over. The nose strips had to be steamed. Read the manual for how to do this. It works well enough. For the landing strips (the 'lands'), I'm doing the "alternative" method that is shown in one of Grain's tutorial videos . I'm running the outside one out the ends. It worked out well and I'd definitely recommend you do it instead of the convoluted approach they say in their manual. I would expect that at some point in the future that they make this the primary way to do it and change their m...
