Richarson drill press spindle
Hi,
I have about 0.01" (0.27mm) run out in the spindle of my Richardson drill.
I've given the chuck a good clean.
I want to inspect the taper of the chuck and spindle.
I assume the nut presses down on the chuck releasing it from the taper.
How do you lock the spindle?
thanks
Andrew

I was given a bench model import drill a few years back that was identical to that set up. No way would the chuck come off with the nut, so I added a bit of heat to loosen it, otherwise it was never coming off. You can put a chuck key in to stop it rotating, or make up a spanner to grip it there..
It must have had a hit on the chuck in transport somewhere as there was a lot of run out. I put it in the lathe and recut the taper to true it up and now it runs true,
being careful I never went up to high.

I've always had success removing these sort of chucks using the following method.
Get as much pressure as you can on the nut, then make sure the jaws of the chuck are retracted into the body full so they don't protrude. Make sure the spindle(quill) is retracted fully up against the stop collar (make sure the stop collar is tight on the quill as well)
Swing the table off to one side and then hold a bit of good hard wood, end grain on, up against the face of the chuck and give the other end of the wood a good whack with a decent hammer. You have to be careful to hit directly on the end as you don't want to hit it on the side. The idea is the nut is putting pressure on the taper and the quick, hard hit, just jar's it enough for the taper to let go.
Using your other pair of hands catch the chuck before it hits the floor. ( or maybe use some duck tape to stop the chuck falling)
This has always worked for me.

Unfortunately the persuader didn't work ..... or maybe I just woosed out.
I did a bit more research and it appears the reason I can't lock the spindle is because its not supposed to lock.
I should be using Jacobs wedges to release the taper. The nut provides an adjustable platform for the wedges to work against.
It's lovely and quiet. Me likes.

what about a ball joint or tie rod removing tool? the sort that has a tapered fork on the end and a big long handle? I've never tried one to remopve a chuck but might be worth considering.
The Richardson is a nice old machine. I've had mine since the mid 1970's and it was old when I got it. It originally had a 3 ph motor with a 3 speed flat belt drive and a flat non swivelling table.
I put a 2 speed washing machine motor on it and ran it like that for about 15 years. Eventually in the early to mid 1990's I gave it a refurb. I fabricated a circular, swivelling table for it and converted it to four speed V belt pulleys. They are only "M" section belt pulleys but they were free at the time. The smaller section belt has never been a problem. When I refurbished it I had access to a well set up machine shop so I made a new pinion for the quill down feed as the old one had lost a tooth at some point and had quite a lot of wear.
I have another 4 step pulley which is on the "to do" list to use to make it a compound drive. Whether or not I ever get around to that is another question.

You might be right Bollie. My glee at the thought of simple tapers might have been premature. The thread is about 1" which is about double the bunnings type gear. In some threads they talk of an arbor rather than a taper. Although how it could be pressed on I'm not sure.
Do you have a picture of your table?

Hello Andrew,
I have a pair of Jacobs No.2 wedges. They measure 15.5mm across the "throat". If you think they might be of use I'll post them to you and you can post them back. Easy enough to knock up a pair -

Thanks for the offer Bob. If I go down the wedge path I'll need to make up some with a 1" throat.

Drill press table pics. The table itself started life as a flywheel on a small Perkins diesel engine. Everything else was fabricated. Not sure exactly when I did this but would have been around 92-93. I've been meaning to make handles to replace the socket head screws but haven't gotten around to do that yet.
