Frame #1

Been a couple of week since I've had any boat work time. Today just wanted to get the members cut and epoxy on frame 1. This is probably the quickest frame to build but one of the hardest to glue up. I layed the frame on top of the ply and screwed through the wood frame into the ply to start with then flipped the assembly over and sent screws through the ply into the solid frame as well. Probably a little over done but I am certain it is well attached for the epoxy to setup.
I also cut the top member today for the transom. Tricky getting the angle cut across the top member. Not sure if I am going with the inboard or out board yet so I will continue on following the plans for inboard as they can be modified easier to accept outboard versus trying to add parts for an inboard.
So far had to scrap about three different boards that developed a crack while cutting frame members out. Devastating but I'll find use of them on somthing I'm sure.

Frame 3 begins

Been a little while since I have posted. Finally found supplier for marine ply and white oak.
I thought I had inspected the wood well enough... well not so. Upon cutting out a frame member the whole plank cracked and split in two pieces right down the middle. I therein selected not to use any part of that board. The other boards fared better and made sound cuts. So I have all the pieces for frame 3 and some pieces for frames 1, 2, 4 and 5. Shame that board broke. I would have had enough lumber to cut all frames except transom. But thats the way it goes.
Got the West Systems epoxy 105 resin and the 205 hardner. Also a couple of canisters of the 404 high density filler.
Finally got the garage up to 60 degrees tonight so I thought I would give it a go on the one frame.
Glen-L gives instrustions on how to build a layout board with centerline refernces and setup line. Found that not too dificult to setup. Still some of the cuts I made with the bandsaw originally are a little wobbly on the outter side of the frame. I hope that once it gets to the fairing portion before siding I can get the lines of the sides a bit smoother with the sander. I am certain I cant be the only person facing this delimma.
Even with the 60 degree temp in the garage the epoxy didnt heat up in the cup, nor did it go to a gel very quickly either. I am hoping it will continue to get to the right consistancy for the bonding.
I opted to use screws (stainless) for the gussetts and floor timber. On reading/studying I found general notes that nails werent really for structure holding but more of a clamping mechanism until the epoxy dries. I thought if the epoxy doesnt set right and doesn't ever solidify at least with screws I will be able to dissasemble, sand it down and try again with warmer weather.
Not a bad start, and hey we're learning here.
