Now that's impressive Denny.
That's way above my level of talent,what are you trying to do? Put Duct tape out of business?

BTW do you have any theories regarding the shape of the hole?

P.S.
Do you ever consider doing a small production run and marketing some of these obscure parts to a select few?
i.e. The Stovebolt gang.......
This may offset some of your pre-production expenses.
Just thinking....
