Trouble Attaching to Spindle of 10ER

Hello;

I hope I am posting this to the proper forum. I have been restoring my grandfathers Shopsmith 10ER (Serial #9717). I had to purchase a new chuck from Shopsmith as that item was missing (item# 505633, Shopsmith Drill Chuck and Key). The issue I am having is getting the chuck on to the spindle shaft. I certainly cannot push the chuck onto the spindle by hand. I have tried to tap it on with a rubber mallet but I did not want to use too much force, as I am worried about damaging the new bearings, or getting the chuck off afterwards.

The other original attachments (sander wheel, lathe attachment, and saw blade attachment) have the same problem, so I am thinking it must be something with the spindle. I don't see any visual dents or damage to the spindle and it does have a small chamfer. When I measure the diameter of the spindle with a digital caliper, it comes out as 0.625" as does the holes for the attachments.


Do I whale on it with the hammer, or file the spindle a little? I wanted to check with the experts before I do something stupid.

Thanks very much.

Joe

You DO NOT want to whale on it with the hammer. Everything should be a very easy slip fit. If you had said the original attachments had problems, I would think dirty bores in them. Since you say a new SS chuck has the same problem I think there is a problem with the spindle. The spindle is very hard material and very hard to damage. Some pictures of your spindle will help.

This link will help you with posting pictures on the forum.

Something does not look right. I looks like there is some kind of collar on the shaft that should not be there. That should not keep an adapter from being installed but something is not right. The main thing is the spindle/shaft needs to be cleaned. It looks OK but very dirty. That is probably your problem.

I suspect the collar should be there, but farther in along the spindle, I think it is there to retain the inner race of the bearing on the spindle, but it should barely protrude from the from the stop rod collar,.

note, the quill may not have the groove for the setscrew.

My question is does the Drill Chuck or other attachments not go on at all or just not all the way?

As John said in his first reply,
The spindle is very hard material and very hard to damage.
That is correct but it is possible to "damage" the Spindle end. If the attachments do not go on at all it may have a slight "mushroom" end possibly caused during improperly changing the bearings or other "work/use." I have had one with that problem and had to carefully remove a little material from the end. It is hard to see for sure from the picture (Closeup with flat facing away from camera) but there looks like some slight burrs on the end of the spindle. Clean it up as previously suggested and work from there. If it has burrs remove them carefully. It is important that the attachments slide on and off easily but have a tight fit.

Both John and Ron have commented on the collar being out to far on the spindle end. How does it look with the Stop Rod Collar removed as compared to the first two pictures in Ron's post? Is it up against the Bearing? If so the Bearing is not correctly installed. Is there a gap between it and the Bearing? If so move the Collar against the bearing. It should then look like the pictures Ron posted.

Just an FYI,

You said in your first post that it is a
Shopsmith 10ER (Serial #9717)
S/N 9717 should be a Shopsmith Model 10E not a 10ER.

So I removed the spindle and front collar,. The front bearing was not pushed down enough. Correcting that fixed the issue Ron and John identified.

When I loosened the front collar, I noticed I could not completely take the collar off the spindle. It would get stuck right at the end of the spindle shaft, where the chamfer begins. So I re-assembled everything and cleaned up the spindle as suggested, which helped a little but not completely. I then took a small file and lightly filed the area right around the chamfer, with the spindle running on the lowest speed. After a few iterations I can get the chuck on with just my hand.

Thanks all with the great suggestions! I am sure I will have more questions in the near future. I have a lot of parts that I don't know what they are. After going through the google doc's area I will post pictures of anything I can't figure out.

Thanks Again,
Joe

For the serial number. We removed the shopsmith plate when we painted the body. During removal, the drill slipped and damaged a bit of the plate. There could be a digit before the 9717 but I cannot tell what it would be. I went out with a pretty powerful magnifying glass and the spot where the number would be is ground away.

There should be an additional number removed by the drilling. That would explain the 4 digits of the serial number not matching a 10ER. Also your Logo/Serial Number Plate does not match the 10E Plates. The missing digit could be any from 1 to 5. A picture of the entire Logo/Serial Number Plate side of the Headstock could help identify it better by showing which Headstock version it is. From your previous picture of the back side of your 10ER it looks like Headstock version 6. Does it have single wedge Quill and Way Tube Locks? Is there a hole behind the Logo/Serial Number Plate? If it is Headstock version 6 your serial number would be most likely 49717 or less likely 59717.
