threading & taps

[avbill]

If I use a Bock feed for my pens There is a distance between the threads and the end approx 3/4"


I now thinking out loud. There could be 2 ways to do thetaping.

1. Would you drill the hole for the size of the tap; and then tap the threads; OR

2. Would you over drill the size hole in the first part of the hole to 5/8" and then tap the remaining hole with the 6.4 x .6 tap.

Which is the stronger support for the feed?


thanks
