chuck removal ..spindle old

[morrisman]

Advice time

WHat would be the ideal way to remove this #2 chuck from the drill press spindle . At a guess, its been on there for 50+ years .

[Bryan]

With a wedge and a hammer, in time-honoured fashion.

Ok I got it out ..but a little damage occured in the process .

turns out its a #3 adapter and a #2 chuck in there .. it was bloody well stuck and needed some heat , I used the small shop press .

As I pressed down the round wedge , it splayed out the oblong hole in the spindle ..now it wont fit into the column ..needs turning in a lathe , but my lathe bed isn't long enough

Otherwise I can carefully grind down the raised area ?

Hi Mike,
I hope you havent bent it?
Could you hold the chuck end of the spindle in a four jaw and support the other end with a fixed steady? (you might have to remove the tailstock completely.)

You need a proper wedge.

Is it possible to get in into the lathe chuck to run a bit of emery on it?

Don't you have a proper MT wedge, Mike? If not, you need to make one (or buy one). It needs to be rounded on one edge and square on the other.
Using a drift as a wedge was clearly not a good idea. Gently file the damaged raised area until the spindel fits again, then polish with some fine emery paper.

YEAH Stuart , a fixed steady would do it , but I don't have one for the Sheraton

Yep I hope it isnt bent too , if it is I am stuffed , but it was very stuck and what else could I do ? .

I didn't want to wack it with a big hammer and really stuff it up.

As joe said , I think a file and emery will be fine .

Mike

PS: its a simple spindle and easily made .. but I would have to use TAFE lathe to do it . Mike

Hi Mike,
The job is done now so these are not much use to you now, but for next time or anyone else these can be bought or made up at home.

These are the wedges Stuart was talking about above, they just have a slot and are tapered from the open end.


And are used like this

... and I was talking about these:

[Dave J]

I have used those for years but you need 3 hands to get something out of the drill press, with holding the quill down, placing the drift in, holding the hammer and catching it before it hits the table when it comes out..
A few years back I bought a few of these below and will never go back to the others.
They where only $10 then and they shot up to $20 odd dollars, but notice now they have come back down to $20 with free postage.
It makes getting a MT out of a extension in your hand so much easier as well.
They work by moving the handle toward the 90deg, the top tapered piece has a gear rack cut into it at the rear, and the handle has a gear on the end, which pulls the tapered piece back.

I also forgot to mention, there is no hammering with the tool above, which will be gentler your spindle bearings.

Ok All

The tips and advice ..great

I tried filing it , but it has bulged out right around the circumference , worse than I thought. The only neat fix is to use a lathe . It files easily , so it's not a hard steel .

Looks like I will have to buy a fixed steady to do this job . Oh well, every lathe needs one and it was a matter of time before the need for one arose .

Nuisance it is !

Hi Mike,
Sorry I had to post and run.
freezing spray works wonders! But with a wedge like Joes(or Daves automatic one)
I guess my lathe is a little far, but if you need it.

Stuart

Mike,
have you measured how much it has bulged? I still think filing may be faster than settin it up accurately in a lathe and turning it parallel. Just checking: you do know what draw filing is? (the careful and accurate way to file a very small amount in line with it's surroundings - in case you don't).
In fact if we are talking a couple of thou, it may even be riskier in the lathe (accidental undercut or excenter).

Hi Morrisman,
Tell me I'm wrong please, but that looks like a No.1 going into a No. 2.

I was thinking the other way, was to upend it & put some CRC or better, & leave it for awhile. But it is out, & that was the main thing.
