Thank you!

This would be an awesome thing to blow up and make one of those hard laminated desk blotter type things out of to leave right on a bench. Feel free to take that one and run with it Tracy should you want to sell them ;).

just in case you don't have a drill chart handy, to find out the drill size for your tap, just subtract the pitch of the thread from the od of the tap.

Ex. for 3/8-16

pitch formula - 1/ threads per inch ex. 1/16 = 0.0625

drill size formula - .375 - .0625 = .3125 which is 5/16

hope this helps somebody
;)
