Man that is pretttttyyy! I've got no oil squirting under the cross slide ways. I can snug that up pretty good and still move it evenly across it's range of travel. Can't I just take the lazy way out on this one and buy one? Some days I just get sick of making crap I need. It's a safe assumption this dude is metric and I found something that looks pretty close from grizzly. I'll try calling them tomorrow and see if they have specifics on what I found. Cheap too! 50bucks for the screw and 30bucks for the nut.
