Drill press chuck problem

**Oldblock** · 8th November 2003, 12:28 PM

Now and again the chuck in my drill press drops out.
Most of the time I am able to put it back with a sharp shove and it stays there, or I give it a little tap with a lump of wood.

Now if I were a machinist I would probably know all about morse tapers and how to humour them but I am not and I dont. So can anyone give me the lowdown on care and maintenance?

You could try some soft chaulk on the taper and then tap it back in

Thats the one! . . . providing there is no oil or grease on the taper.

If it has some lubricant of any sort, clean it with some turps, petrol thinner or the like, let it dry and apply chalk . . .dont forget to clean and dry the chuck's tapered hole too!

I've never heard it called that before.

Oh I get it. Would that be before or after application?

It takes a decent whack to get it in to stay.

I was using a 4x2 but I felt the spin was wobbling.

I then stacked hard wood and tried to press it in.

Then I had a flash and used the superjaws on it.

Haven't had a problem with it since.

Barry,
Are we talking about the same thing?

This is what I'm talkin about:

Although, I did use the chalk on my hands to make sure the 4x2 didn't slip out of my hands.

If that arbor of the chuck keeps coming out there is something wrong with either the morse taper of the arbor or the morse taper of the drill press. Try a mates arbor in your press, if it stays in, you know the chuck arbor is at fault and u can return it to the supplier.

I agree that it is an unusual problem, and that there could be a fault, as for Barry's whack with hardwood or superjaws . . . hum no idea. . . .actualy why not a one kilo mallet?

I can imagine Barry holding up the superjaws over his head to press the chuck in place on the drill press . . . .imagine the shape of the pulley cover or the pulley after such treatement . . . .he he

Opened the cover

packed the top with hardwood

clamped with jaws and exerted pressure with foot

Just checked - every so slight wobble

just curious - has anyone else had a good look while the drill press is running ?

do you get a slight wobble as well ?

Oh right, the wobble I've been addressing is the wobble I get when the dp is running. This might have been misleading. appologies.
