Don R made a pattern for me awhile back.Had two excellent patterns, other one was by Br4.
customer opted for Dons as it was a close up.here are the picture, pattern, and cut.
I use gorilla glue to attach the over lay..I find when I spread it thin,there is
not much squeeze out.and when it does it is very easy to remove with sharp knife.
Also I find sometimes it acts as good as a filler...my thoughts
I had similar yesterday. Made up address sign and at the end, found out wood had a stress crack.
Then more time trying to glue it, then tossed it in pile.Takes the fun out of it.
