Squaring the transom joint

Post by jbo_c »

How have y’all built your dams for adding material to sharpen the transom joint on your boats? Specifically, how did you attach the material for the mold? Last time I did it, I use caulk to attach the dam temporarily to the transom side so I could “pour” from the bottom. It worked, but where the fill flowed down to the caulk line was very uneven and took a good bit of(I thought) unnecessary fairing.

Thinking maybe somebody has a better way.

Thanks.

The fill should not be so thin it flows.

If the boat is upside down, make a board with shipping tape on it that extends the entire transom. Find a way to apply pressure to it. I prefer clamps at the top of the transom and more pieces of wood. If you use a piece of 3/4" lumber at the bottom; use a piece 1" wide at the top and when you run your vertical pieces of wood ; the clamping will add pressure to the transom bottom more.

Precoat the area with clear epoxy first for better bonding of the thickened resins. Wait an hour and trowel in the thickened..

Thanks. Sounds doable. Also sounds like I need to make my “mud” just a little thicker for this application.
