Drill Press Setup P2: Arbor & Runout Adjustments

[@michaelrobinson9643]

The only way to alter deflection with the set screw is to remove the quill because it has a square head that fits in the keyway. You can tighten it a half turn which will push it against the quill firmly and reduce L-R quill movement. Grinding the head round like a pin that is perfectly fit to the keyway is actually FAR better for offering an adjustable control for quill wobble while still being an anti-rotation key.

Now do the nod on the table- mine droops front to back.. I was taught when installing the Morse taper to lightly heat the quill to expand it before tapping it home and then do the same to the chuck.

Finally found youre video about that problem.. Same problem

[@hawkenman.549]

I ran into the same problem with the drill press I have. It’s one from Harbor Freight. I removed the plastic housing on the front of the machine that has the on/off switch. The case is actually split and there are ears that have large adjusting bolts. You can tighten them to take up the slack on the quill. Hope this helps someone. Not sure if other brands are made this way.

It's so interesting and useful for me. Thank you!

[@twalsh1490]

Thanks! Just picked up a 20 year old drill press which turns out to have a noticeable runout problem. Looking forward to following your method.

So what was the actual problem that was fixed

[@michaelklaman7394]

What is the name of the solvent you used to remove the corrison from the arbor of the drill press?

[@jeremykemp3782]

I would have liked to see if there would be any total run-out with the press extended out fully.

[@WayneCook306]

That is NOT the correct way to set that adjusting screw, It has a flat spot and you need to remove the quill to adjust it..

[@chrisrschroeder]

Can you describe the correct way to remove the quill and make the adjustment or provide a link?

[@markkoons7488]

Bought a 20" Taiwanese drill press third hand. As with other used drill presses, dirt, loose fasteners, and rotted rubber were behind 95% of the problems. It would be nice to know how to clean, lube and adjust chucks, too, wouldn't it?

[@jimgresham5529]

Yeah right, if you don't fix it a bolt won't fit in the holes.

[@altimmons]

I’ve been trying to fix mine for a while. Mine is not new. And it’s second hand. But it’s what I’ve got for now. It used to have a little wobble. Now it has a ton. I cannot figure out where it’s coming from.

[@jeremykemp3782]

very good video

[@jimgresham5529]

Just how precise does a round hole gotta be ? Your building a nuclear reactor right ?

[@michaell7877]

Where did you get that stand (dial indicator) for the gauge?

[@deanmiller9039]

Ahhh, am I missing something here? Started out with 9 thou runout, then cleaned it all up and ended up with 9 thou runout which you were happy with. Thus the runout procedure accomplished nothing?

[@grooooved]

Yes, you're missing something.

[@valuedcustomer9614]

Watch it again. He said run-out improved from 9.0 to 0.5 one-thousandths/inch.

[@Hoaxer51]

I think what you really want to show is .009, nine thousandths and .005, five thousandths. What you’re showing is 9.0= 9 inches and .5 is a half an inch. Edit: After rewatching the video, he said he had it to one half a thousandths witch is .0005.
