UN-stuck Drive (1236)

Mark Mandell - Gone Round In Jersey

>Thanks for the suggestions and advice.

Went with the Split Nut Method,to which I added a 3/4"id washer with a slot cut.

Pegged the spindle and snugged up the nut, leaned on the wrench . . *boink* out she came. Friend is getting another 1x8 nut to which I'll weld a 3/4"id heavy washer and, from now on, that little appliance will now go on the spindle BEFORE the spur drive gets inserted.

Strange (but fortunately) there was not a mark on the taper surfaces; no gauling, nuthin'.

Thanks again Group.

Mark

>Good job Mark

The reason why ? I assume that the tail stock was tightened more than you did normally, with the added strain the bearings and than the shaft got warmer than normal, leading the taper to seat in deeper, and as soon as the lathe stops and cools down your taper gets squeezed tighter and the rest is history, just musing as Arch would say.

Have fun and take care

>Don't think so, Leo. The kid was turning a candlestick, so we drilled the socket end, and put just enough pressure to have the live center hold, but not split the piece.

But also, I noted that the spindle was warm, although slightly. It was a 3+ hour session and the lathe hadn't even been spun for almost 2 years (friend bought it from me when I got my Stubby). Possible the spindle and bearings got a bit warm on their own. Puppy was TIGHT.

You'r probably right Mark

>It is likely the temperature that I also thought was the culprit, only the reason of how it got higher is not how I thought it did, It is very possible that the bearings have gotten some oxidation in them after sitting without use, might shorten their life possible too.
