As a followup to my previous post, the height from compound to cutter tip on this toolpost is a whopping 1.62" if using 1/2" HSS bits or indexing toolholders (0.560" from compound to underside of turret, 0.560" for lower turret land, and 0.500" for the tool itself). Way too high for my 10R, which according to the documentation is supposed to be 1.03125" from compound to center (and by my measure isn't far off). I thought briefly of modifying it, taking the base down to 0.125" stickout and milling another 0.125" off the tool channels to bring the tool tip down to my height, but I can't in good conscience ruin what could be a perfect toolpost for someone else.
I'm going to clean this up and take some pics with measurements and post them here. If I don't get any bites after a week, I'll put it back on ebay.
