Alluminum Bronze: AB2
Made quite a few bushes out of this material in the last year and geez it is not bad boring wise, but drilling and reaming still drive me nutz.
Has anybody had similar issues that may have overcome this nightmare.
Drilling wise i have been grinding drills just slightly off-set so they won't grab. Still iffy!
Reaming wise is an absolute hell mission, talking small reamers that is, under 1/2 inch.
Cheers, BT. |
