"glue and screw" question

[WillyC]

Thanks for the advice Stoney. Your picture and the one Scott posted of your boat are great. I plan on doing almost exactly the same thing as you. I have already laid a layer of 1708 biaxial on the inside skin of the transom including strips in the corners (sides and bottom). Maybe this weekend, if Rita doesn't reek havoc over here I can get the coosa bonded in. Its not that important at this stage but im still wondering if the 20 footers need any additional transom support such as knees. Thanks -Will

To answer your other question I used 3/8" plated allthread. I double nutted one side. After the big glue event with SLOW set epoxy the allthreads backed out no problem. I put an allthread everywhere there was a hole in the transom, like drain plug motor mount holes, drain holes etc. I will defer to others who know more about repairs and 20 foot seacrafts, BUT the knees weigh almost nothing. There are lots of other posts of people rebuilding the transom and putting them in. The point of all this work is to make the boat better and NEVER have to do it again. If you put the knees in drill through holes for drainage BEFORE installation.

As to the bolt/glue question, just put wax on them before you laminate, and they will back right out. I have never had a problem with this method. If you are nervous about the wax, use McLube (available at West Marine) which is a dry film lube. Coat the screws, let dry for a few minutes, and then let the glue fly.

I have used both methods with great success.

This question has to do with re-enforcing the transom: has anyone used "carbon fibers"? Where in the transom do they go? - Thanks for info, aaf
