Checking in from Louisiana.
Great info you all have here, hope to contribute some of my own at some point. I hunt everything except birds. I'm a machinist by trade, I'm a lic. manufacturer of suppressors, short barreled rifles, short barreled shot guns etc. I shoot competitive pistols in USPSA. Generally just have fun

Nope.
That might work for a very coarse and deep thread.
The 32 tpi threads are only a few pubes deep.

Dave,
According to this very useful website
http://theoreticalmachinist.com/TapDrillSizeCalc.aspx
The drill size for a 1" 32TPI UN thread is 31/32"
Cheers
Bruce
