Bob you are a lucky guy, your wife likes your hobby.
My parents had 8 kids in 8 years, no twins, two in the same year and than 4 kids after that . Having 8 sisters is not fun, LOL. This is why I say a lock. Funny I think that way because mom does not like dads hobby of fishing but would never touch his stuff, my sisters on the other hand........ LOL
Good luck with your shop.
