chuck removal ..spindle old

[morrisman]

Advice time :oo:

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.

[morrisman]

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?

Dave

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 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

[jhovel]

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.

[morrisman]

I have to take off 6 thou ... over about a 3/4 length .

Thanks for all the interest . it will turn out OK .

Your immediate job reminded me of the Drummond Lathe you purchased recently.
Has the lathe been put into operation as yet?

Hi Bruce ,

I am planning on buying a new 3" or 4" chuck for the Drummond, it deserves a new one . Nothing brings an old lathe back to life like fitting a new chuck does :2tsup:

Like all of us, I have too many projects on the go . The temptation to take on one more is hard to resist .

I am with you on this.:2tsup:
I am currently negotiating purchase of an old flat belt drive 9" Hercus of WW2 era. Seeing I already I have a lathe, I really dont need another, but this one is so original that I have to "save" it.
Yes, I agree a new chuck can really make a lathe.
I think its good to have a lot on the go, it keeps one thinking & young.
Anyway these are my thoughts :).

Correction Hercus should have read South Bend

Quick update: I managed to repair the spindle OK . I filed and filed the raised area and polished with wet/dry paper til it slid into the column and rotated freely.

Yes it was bent at the point where I had pressed it .. 25 thou runout . In order to repair this , I rotated the spindle around 180 degrees , put it back in the press and pressed on the opposite side to where I had first pressed . After a few adjustments of pressure and measuring it's now down to nil runout . Good enough for a big drill :2tsup:

A lesson learnt though .

MIKE

PS I have one of those morse taper remove gadgets on the way from OMNESTORE ..thanks Dave for the info

[pipeclay]

Nill runout is good for any drill no matter what size,any closer and you might of been getting close.

[Dave J]

Mike,
Good to hear you have it sorted, I am sure everyone (I know I have) has done something like that over the years and wishes you could go back in time. Good save anyway.:2tsup:

With that tool, I found I had to take a little material off the side of the blades on one of mine as it was a little to wide to fit the MT properly. I did this with a flap disk in the hand grinder, it didn't need much at all, but was slightly tight.
It seemed to be made really hard metal.

Pipeclay,
You could be right there, LOL
