Well, took a couple of years off from doing this build, getting back to it. The advantage of that is that I have been able to look at Cracker Larry's and Larry B's progress, I am so grateful that you guys take the time to post pics and comments. I won't be able to keep up with those excellent examples, but will try to post any helpful comments if I have any that you guys have not already posted, although those will probably be few and far between.
I have gotten to the point of putting the hull together, puttying the inside fillets, flipping the boat and have so far taped the transom and bow. I have faired out the two side panel seams that need taping and have coated with epoxy, now waiting for that to get dry enough to tape. I have attempted to read as many posts and how-to files as possible so that I don't ask too many newby questions but, inevitably, I still need help. My thanks in advance to any who do so. Here is the first salvo of questions.
1) Restudying the plans, they call for a 2x6 for the stringers. I chose to laminate mine out of 1/2 inch ply of three layers, leaving them 1 inch higher than plans for the drainage issue. I did not see where the stringers were to be tabbed onto the keel panels, but CL did his so should I do mine? Also, I see CL used a thicker lamination, I only did mine to the 1-1/2 inch to match the dimensional lumber thickness. If I do need to tab them in, what cloth, the biax or will the tape work? Totally encaplulated or just tabbed in at the bottom corners?
2) I seem to be using a buttload of epoxy which, according to this website is to be expected from a newby. I am definitely guilty of making large fillets on the inide seems which is where some is wasted, but, I seem to use a ton when wetting out the biax tape. My past experience with poly resins is to wet out the area that the tape is going to be applied (not talking about the initial layer of epoxy used to soak the wood, already have that done and dried and sanded or still slightly tacky when working wet on wet), then laying the tape on the wet surface, then wetting out further with a foam roller. Is that proper, or should I be laying tape on the dry seam and wetting out from the top?
3) I see that acetone is the preffered chemical for wiping down surfaces before putting epoxy on. I am using MEK, will that cause any issues?
I posted some picks in my gallery and will try to keep doing so. Hagar's OD18. Maybe as time goes on I will get smart enough to include that url in the post...
Thanks for any input,
Hagar
