I was afraid of that. But I'll have to cobble up the press, probably from a 3 legged gear puller. Getting a pulley I already have, bored concentric is part of the problem since I don't have chuck jaws that can grip it on the pulley, but on the flanges. None of the flanges I have checked are concentric with the shaft bores because thats actually a 3 piece assembly pressed together. Resting on the flange, the bores aren't even perpendicular. Chuck jaws grab both flanges, tipping it, and I wind up taking a stroke or 7 with a file before a dial says I'm good. A pima. But you knew all that. ;-) I'll sort something out. But I'll have to fix my bandsaw first. I have a 111 inch metal cutting blade for it on order, and then I have to make a new table insert. One that will sit exactly flush with the table. The OEM insert was some sort of fiberous polycarb, but sat too low, allowing a small block of alu to tip forward into the blade, locking the blade and wrecking a 3 tpi woodslicer blade and smashing the plastic insert. The next one will sit flush but its a bastard measurement, about .198 or .199 thick and I might have to fit setscrews to level it. But now I have some 7075-T6 to make it from. Even for wood, that OEM insert is dangerous because it sits 30 %#&@$! thou below the table. > Dave Caroline Thanks Dave.
