Transom repair, two layers of plywood

[tiku]

One question that I have

I am using two pieces of plywood to construct the transom (2 x 21 mm thick plywood) So my question is that would it be best to first epoxy the first piece to the existing fiberglass transom and then after it has dried epoxy the other one on top?

I think that it would be easier to construct it this way but will this have any negative impacts? Like deforming the transom or something similar?

Has anyone done it this way? I would think that it should be ok..

Just curious as to why you think this would be easier than gluing them together first.

Good question, maybe I should clear it a bit. I'm working with limited spaces as I have decided to still keep the cap on the boat It's currently a tight fit to get the plywood pieces in.

Secondly and perhaps more importantly I think that it would be easier to fill the gaps that are left after epoxying the plywood?s to place. In other words I could make sure that there are no spots that I have missed. I think that it would be easier to fill them if I were to construct the transom piece by piece.

All in all, I 'm getting the feeling that it really does not matter how I do it.. Still, it's my first transom fix and I want to be sure that it' done right.

I'm a few steps behind you (I'm cleaning out all the rot right now), but one thing I've been learning is the tolerances are pretty tight.

I don't know if you're Outboard or I/O, but my Alpha One needs a thickness between 2" and 2 1/4", and the inner and outer surfaces need to be flat and completely parallel to within 1/8". To me, it'd be easier to make sure everything the plywood pieces are flat and parallel if I epoxy them together on sawhorses parallel to the ground, rather than trying to do it on an angle in the boat.
