Reply To: Transom building questions

Replies appreciated.

I think I can see my way through removal and installation, (although it’s not out yet, after three hard days!)

But I’m no woodworker, and will be happy for any guidance.

I’m tailoring plans I see on (https://www.boatdesign.net/threads/replacing-transom-on-aluminum-boat.36711/).

In short, I’ll use three layers of 1/2″ marine plywood, each coated twice and allowed to cure, then bonded with more epoxy plus hardener and fibers.

Thinking of using WEST systems 105 resin and 206 slow hardener. Working conditions will be about 80 degrees and low humidity.

The plans say to bed the finished transom into the boat with more epoxy. I try to work with the, “next guy” in mind, but I like the idea of strength. Opinions?

I don’t want to drill mounting holes over-sized, fill them with resin, and then redrill. I can see why this is good, but I’m not sure about the long term health of two dissimilar materials under stress. Do I need to rethink this?

Any special blind or, “pop” rivets needed? They look like the ones I’d get at the local hardware store. It’s a 1969 Lund Aluminum, 19’…

OK; please pick this plan over mercilessly and let me know how I can improve.
I very much appreciate the support, as I head out to fight with it on day #4, just the get the old one out.
