Zippy Basher's Rides

[lincpimp]

Al is very easy to thread. I do alot of mine with just a screwdrive style tap holder and a steady hand. M3 and m4 threads usually do not even require any cutting oil. Just go slow, and when you feel some resistance turn the tab backwards 1/8 of a turn or so.

Best method I found to getting holes tapped perfect was to chuck the tap into the drill press and just turn it by hand while advancing it with light pressure on the press handle.
