Topic tags/keywords: question drill press

I have a Craftsman 2/3HP drill press. Lately the Chuck has been coming off a lot. I take a rubber mallet and get it back on. It feels secure, but shortly after use it comes off again. Obviously this is annoying. Does anyone have any suggestions?

Thanks,
Jeff

How about cleaning the taper fitting and hole with some very fine emery cloth or steel wool and then wipe down both with a solvent like mineral spirits.

Is there not a screw in the end of the shaft to hold the chuck onto the shaft?

I am having a similar problem with a (believe it or not) Toro drill press. I inherited it from my grandfather, and I am guessing the vintage is early fifties.

Clean both like lew suggested. To seat it properly I always just put a block of wood on the DP table and press it on by lowering the spindle.

EDIT: Make sure the chuck is all the way open when reseating.

If it just wont grab, check the spindle taper for flaws. one or the other might need some reaming to clean up the taper.

Great idea! Better than mashing it with a mallet.

some people put a little very thin tissue paper on the chuck before refitting it it may work watch it does not produce run out though try first seeing what the problem ios is the chuch taper clean and burr free and the corresponing mating surface in the spindle shaft if so try what I said.don’t wallop it with a hammer or mallet Alistair
