This is my version of a Shipwright design. If I am disremembering I apologize to whomever originally posted the design.
As a note: There are small bumps on the mounting bracket dwells so the jig cam locks over the tubes to keep the jig from moving during use.
I create problem solving challenges and opportunities for design modification, not mistakes.
