Lyman 45 alteration..

[Newfoundlander2]

I'm sure it's been asked before but can the Lyman 45 be tapped to accept a 450 die retainig nut?

Look and see how much "meat" there is where it has to go. If there is metal
it would be possible. HOWEVER, buying a tap that large new is usually pretty
expensive and tapping it accurately would take a nice fixture, so would likely
be costly to get done really straight, which is pretty critical.
