Spindle is R-8, and I bought a full kit of collets in fractional inch, I'll have to see if one of them fits a 16mm screw. If not, or I can't hold it tight enough, I'll see about the superglue on the pads idea, and an hour or so's heating of the lash adjuster nut with the hot air gun. 800 grit I don't have, but 600 wet-r-dry I have several sheets of. Since the head is off, I could use the spindle if I could figure a way to lock it solidly. The pin Grizzy supplies as a spindle locker does NOT fit the pin hole for spindle locking at all well. Way the heck too small a tip, and too long too. I feel a session on the little mill, making a half circle spanner might be worthwhile. Or even making a copy of their $90 spindle lock, I'll need it anyway. Thanks Christopher, the idea might be just what the Doctor ordered. I'll see w/o the sandpaper first, since if it slips, its the top of the threads that would get marred. If theres room, it just now strikes me that a few wraps of alu foil might be a traction helper. Does _anyone_ have an idea where replacement teflon seals might be sourced? The one it pushed out is pretty well mangled. Thanks all. > N.
