I got this for $3...
5/32 - 1/2 (1 -13mm) Rohm Prima l.
It is mechanicälly sound (moves freely and keys tighten/loosen fine), the clamps are pristine, and it has about 0.08mm runout (3 to 4 thou) at 5mm past the clamps, which is basically just my lathe spindle runout amplifîed by length.
It had a heap of rust all over, so much I couldn't read the brand name until I wire brushed it. Otherwise I washed & wd40'd it to get some of the crud out. It is on some weird waisted/flatted straight extension with a 5/8“-16 thread... almost looks like it is a piece of the drill press it fell out of. These chucks cost $200nzd... Apparently. I wouldn't pay close to that for a f..king drill chuck. But still, seems like it is worth taking some amount of care with.
Wondering if I should attempt to get the arbor out, and if anyone has any thoughts about further cleaning/lubing.
I was thinking I would just brush/sand the outsides, blue the knurled bit and maybe the, uh, spinny round key hole bit, spindle oil the gear and gap behind the gear, then turn a sleeve to hold it in my tailstock.
