More cold mdung

Fitted and glued another 18 or so strips. I have gone about as far forward as I can on the bottom on one side. Now I have to start using thinner strips. Haven't figured out how much thinner they need to be yet.

Cold molding

Didn't get as far as I had hoped due to the arrival of a cold. The cold didn't dampen the motivation but its really hard to glue stuff when your nose won't stop running.

Never the less I got about 12 strips glued on.

I also cut up another couple of sheets into 100mm strips. This task is a real mission by yourself. After making a bit of a hash of the first one, my neighbor came over and helped me cut the sheet in half. Once in half they are quite manageable by oneself.

I think that was the first time I have had to get help in this build.

Raptor nylon brads ROCK !!!!

The plans allow for a ply sheet to cover the entire bottom from the transom to frame 3, so this weekend I stuck a sheet (part of) on each side.  These were glued and fastened wit the nylon Raptor brads.

I think I went a little overboard as a rough count suggests I shot about 600 of them.  Some of them don't sink in properly, but I think that's just hitting a hard spot in the Sapelle. I am also not using a Raptor gun, but a second hand (although looked brand new) one I bought from trade-me (NZ version of e-bay).  I tried Craig's genuine Raptor gun, but I don't think it made enough difference to justify the $300 or so that they cost.  You can see my gun in the photo below.  Should add it to the tools page I suppose as well

As the layers progress they will be shooting into more and more plywood and so should just keep getting better.

Having succeeded at getting the two sheets fastened on Saturday, Today I moved on to fitting some of the 100mm wide strips I had cut from the left overs.  I choose an angle of 30 deg and have made them sweep back from the keel.  I fitted 6 strips then made up a batch of glue.  Turns out I only made enough glue to fix down four of them, but it was quick and easy work with the brads.

At this point I am fixing ply to a relatively flat surface, the real test will come when the curve starts to become pronoucned.  So far so good

It is amazing how the newly formed flat surface quickly become a place to store "stuff"

Cleaning out the limbers proved easy, I was worried that was going to be hard to get them nice a clear.  I got a piece of dowel, took to it with the plane a bit then if slide easily through the limbers.  Unfortunately I made it two long and I couldn't get it through the athwart ship ones at the transom.  I was going to cut it down, but then forgot, and by the time I remembered it was too late.  I haven't checked, but hopefully they aren't too blocked, none of the others were.
