With scraper type drill bits and LARGE dia. spiral bits, Low speed with Higher pressure and oil Lubricant seems to work best for us.

Your experience may vary.

Perhaps the reason the soapy water works well with my toy drill press stuck in granny low is that even though it's torque has been greatly increased it's still driven by two 'A' belts. The 1 1/4'' holes are done in 5 steps and the final hole from 7/8'' to 1 1/4 is nowhere near done with ''high pressure'', if it's just cutting I don't push It harder or the belt will slip. I miss my Bridgeport....Cry....But this gets the job done....Cool

IT'S ALIVE!.... [Image Can Not Be Found] .... After much hassling with the pendant I finally got it. It's actually more sensitive with the electric valve than the manual spool valve. I don't have any but I'm sure it will curve 3/4x1 1/2'' cold on edge (with the widest pin setting) like it's predecessor. I use the ''doughnuts'' so as to not mar the workpiece or the pins. The pins are W1 which has a rockwell hardness of 21 in the annealed state which I hoped would be hard enough to prevent them from marring but they'll need to heat treated......the shown in the bender is 1'' sq.

A few final touches...I built a lil' tweaker attachment(s) to do small stuff; the piece in the pics is 7/16 rd. The static piece that has the two 5/8'' rounds welded to it for the bending form can be turned 180* and have a different form welded to it in the future.

Since this attachment covers the small stuff I'm thinkin' I just might put my Diacro #3 on the block.....Great tool, but I wouldn't miss walking around it's 3 foot handle.
Two new outboard form pin holders are shown as well.

Slick..
A local guy just called me asking If I knew of a DiAcro #3 for sale. When you put a price on it let me know, or I'll just give you his number...

Whatever you are, be a good one.
