Question on Zip transom

Postby Bill W » Tue Dec 27, 2016 7:07 pm

On the zip plans, I see the sides and bottom members of the transom frame, but not real clear if there is a top frame member. If there is it seems to taper very thin at the center.

Any help will be appreciated.

Bill,

There are top members of the frame, yes. However, they are two separate pieces that butt up against the motor board.

There is not a full-width frame member across the top of the transom on the Zip.

Here is a photo of my transom frame. I hope this helps.

The taper where the top pieces meet the motor board is indeed very thin.

Okay I see it now. Great help, thanks. Did you glue the frame members together or wait and attach directly to transom ?

I did not attach the frame parts together separately from the transom, no.

I glued the frame parts directly to the transom, using thickened epoxy and a lot of clamps. So far, I have not used any screws on the transom.

I attached the pieces all together in multiple stages. First, I attached the motor board:

Then after the epoxy cured, I attached the floor beam and the sides:

Once the epoxy for those parts cured, I attached the top pieces. The key is to cleanly scrape epoxy away from the corners where the miscellaneous frame parts meet the transom. Otherwise, if you let a "bead" of epoxy solidify there, it creates a real headache trying to fit the next piece into place. I use a simple flexible putty knife to scrape away epoxy squeeze-out.
