And here's a guy who knows his stuff in a shop that would make an OSHA
inspector's head explode
https://www.youtube.com/watch?v=R7ljMcBqvG4. Oval starts around 9
minutes.

Holy crap! There's one guy who *really* needs a SawStop! Sheesh!

OP: I asked for help in making an oval frame, not for bad examples using
badly designed power tool. It was amazing that he still had all his parts.

On looking at some video that I found and what has been presented, my
concern was making putting the sides together.

This is a rather large mirror with the major axis about 30 inches and
the minor axis about 20 inches. To find a board 20+ inches, is going
to be difficult.

My thoughts was to glue up pieces is the approximate shape of the oval
and then cut the oval from that. There is one video where the working
shape is a lay up of small triangles, to give the approximate shape of
the oval and another where he makes the approximate shape out of
rhomboids and glues them together.

May be I am over thinking the problem but I was looking for the best lay
out using standard stock material and the angles to make the cuts. (it
is 50 years since I have had geometry.)

Maybe the best way is trial and error.
