Keyless Drill Chuck

[dannyshamoon]

Does anyone know if the Grizzly 5/8" arbor chuck will work on a shopsmith 500?

For $20 it might be worth it but since you didn't ask about quality just if it would fit.......... from the description it might. The issue being the set screws will/might not align to the flat on the shopsmith quill shaft and could well damage the quill....... if not. I'd say you are risking a lot to save a little.

I bought a keyless chuck I found on Ebay that looks to be the heft of the SS one but definitely is not. It does seem heavy duty and has the grab ring same as the SS one. It is drilled and tapped for a set screw that is NOT a typical SS diameter and 90 degrees.
One of my projects when I am able to get back in to the garage is to drill and tap another hole on the opposite side of the existing set screws which is the correct angle for the shaft and the common diameter used for SS.
You could drill and tap the Grizzly one to match the SS shaft and thereby reduce the possibility of damaging the shaft with a non-SS part.

Be well,

That can certainly be done but I question the absolute necessity of it. The 10ER has the same quill shaft as the MK 5/V. AFAIK all 10ER arbors are drilled at 90°. I have some MK V arbors here that are also drilled at 90°. Also, has anyone ever seen a SS quill shaft damaged from a set screw? I have no idea what hardness of the steel is but it is HARD. I have five 60+ year old 10ER's here and the only ware any of them have is the blackened coating around the set screw area.

John, the saw arbors may be, but the
"rest of the spindle stuff" isn't.

There are a couple of issues here. The pictured item is designed to mount on a motor shaft. We have no idea of the distance it is designed to go on to the shaft. We have no idea where the set screws are located, perhaps one would be close enough to the end to have a good position on the shopsmith quill or well, not. The second set screw, who knows where that would be located, not likely on the flat so do you use it or not??

Now the set screws are likely designed to grip a plain shaft, perhaps a cupped end, or maybe some other thing like a cone point or knurled cup. Not likely to be a nice flat point or oval point. So again another unknown.

Yes you might get lucky and find a single one of the set screws sits on the sweet spot of the shopsmith quill and yes you could replace the set screw(s).

Will a 5/32" allen wrench work in those set screws? It sure is nice to have just one allen wrench to fit all of your accessory. I know the 10 series machines had different sizes allen screws and I don't like that. OK time to put the chuck on, now what did I do with that ?/?? or ? mm wrench....

Now you can ignore the lack of an angles set screw, fine by me I was not the one that did the design work on the shopsmith I'm just the one pointing out that that is how it is now.

Yes one could drill and tap the shaft to get a better situation and that is fine if you have another drill press to do the drilling and own the bit and tap.........

As to the question as to damage to a shaft...... I personally replaced a quill because the previous owner messed it up. Not sure what they had mounted but it wasn't far enough on the quill and looked to be a cup point and it twisted and smeared the shaft. It was damaged enough that I went for a whole new two bearing quill.

New from shopsmith:

If you can't afford the price of a new one from shopsmith then check ebay, I haven't been looking in a while but I now they use to show up pretty regular, shouldn't have too much more then half that price there.
