Cutting beveled notches in the transom

I made a little guide with a 10° bevel on one side, and a 12° bevel on the other. I clamped it into place and used it to help me cut the beveled notches for the sheers, chine, and keel with my multi-tool.

After a little goof from over cutting the first notch, I started clamping a fence into place for the 90° cuts.

The 12° cut is for the keel.

I cut the transom from back-to-front, since the aft-most dimensions are what is marked on the plans. So far, I have not cut any notches for the floor battens. That is because I haven't yet decided if I want to use 3 battens per side, or only 2 (as specified in the plans). I also haven't yet decided — if I do opt for 2 battens per side — whether to use 2" wide battens (as specified), or 2-1/2" wide.

Decisions, decisions...
