Got the braces glued on, gave the titebond III an hour to get a grip and finished the Grizzly 7/8 R8 so its usable, but when I switched it out for the first of the Korean ones it sounded different when the tool touched. Went ahead and drove the machine with what should have cut a 7mm wide "key", but when testing for fit, the screw head was half a mm bigger than the cut. Stopped the spindle, and the leading edge of the flutes of a 3 flute, very high twist SC mill I had sourced from ebay a few months back as part of a 2-4-6-8mm kit for about a $20 bill, were all shattered away for about a mm back from the edge. I can finish the cut with a dremel, but these things are HARDENED. And I only have US sourced 1/4" 4 fluter's left. I'll go waste one of those. Or finish it with the die grinder, then try one of my 1/4" 4 fluter's on #3. Which just proves that nothing is ever as simple as it appears... EDM maybe? I can do that too, on the little mill. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
