Locking the Main Spindle

[Skizzity]

I wanted to keep my piece on the lathe and drill my entry and perch holes for my miniature birdhouse ornament.

This is my quick and easy solution to lock the main spindle from rotating. The auxiliary spindles aren't moving and the main spindle has a tad amount of rotational play but good enough.

Nice

I have a tapered shaft I put into the tail stock and put the chuck on it , but that works.

I could have done the same, unlocked the headstock, slid it back and gone through the process of switching the chuck over to the tailstock, drilling the holes and then switching the chuck back over to the main spindle and re-setup. I would argue the clamps and retracting the quill a little is quicker.

Locking the drive shafts as shown does prevent rotation but the play between the spindled shaft and the plastic coupling will not be eliminated. That movement can be dealt with only at the spindle end.

I don't have one of these right now but I soon will. It is my idea for eliminating the unintentional rotation of the spindle when performing tasks such as was described in this thread. I have something similar that serves as a facing on my 510 rip fence. The magnets secure a steel ruler embedded in the fence.

This won't work in your specific application because you don't have the blade mounted but it might give you an idea worth pursuing. This jig resting on the main table top and attached magnetically to a blade or alignment plate mounted on the spindle prevents rotation of the spindle. It is not absolute because the magnetic field is not that strong but it does resist accidental rotation. Just a thought.

"quick and easy" was the OP qualifier.

Well, I guess you can't get much quicker or much easier than applying a clamp.

Two clamps.
