Mine isn't hardened then, files nice & clean. Didn't even hurt the chinese 14" mill bastard. >I repaired the 6 >foot bed of my Sheldon >15" lathe Nice machine! >by hand techniques.

This worked but >was VERY slow. > Yeah. slow... I went to see about mine and the first thing I did was semi- mangle the first 1/2" of threads on the compound feed screw cuz it was so stiff. So I pull it off in small pieces and polished it here and there, on an oiled sheet of 600 wet-r-dry on my surface plate, finally got it to where I could move it by hand, then spent about 2 hours trying to rescue the threads. It's working much better now. I also 'scraped' it here and there with one of those 1.5" diamond wheels in a dremel turning about 5 grand, then used a 14 volt drill to run the screw end to end about 50 times, pulling it and wiping it off, till that was hand turn-able again, then found the bushing behind the calibration dial had to have its screw holes bored out to the next bigger American drill size for additional wiggle room cuz the screw wasn't pointed right at it when screwed all the way in. You get what you pay for, and I only paid $300 for this one cuz it was missing parts. They sent them gratis after I'd taken inventory to see what was missing though. Taint great, but its better than none at all. Just barely... :) -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
