Unforch Les, that would be a hand job as I've lost my touch at getting the correct heel height by eyeball (and ATM they are way out of calibration from cataract surgery) and Drill Doctors don't go that steep. If I can find a narrower clamp so I could drill on both sides of it to prevent the flex from allowing it to dig thru by grabbing the panel. I'll investigate it in scraps of this material. Someday I'll build me a sharpener out of the A table, which would make it easy to set the angles. A table, a steady rest for this piece of crap table I have, and a dremel spinning a diamond disk could probably be a better sharpener than a Drill Doctor, and spend a week sharpening the whole box of drills. I must have 5+ kilo's of semi-dull ones now. :) Thanks & Merry Christmas, Les. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
