Well.... Another "new" greenie

[mikelst]

Why is it that filing is not considered???? It is much less traumatic to the object being 'fixed'!


The inner one is different!

Actually the belt sander was right next to the press where I was installing the bearings when I noticed the burs... I guess it was just easier to use it than going to find a file. Not a good reason maybe but that is what happened.

I need to look but I don't think there was a way for the gilmer drive assembly to come out from the casting, it had to go in after removing the spiral lock on the inside... Does this seem right???

I need to go look at the casting.

No, it seems bass ackwards.

The 'spiral lock' is a retaining ring that goes around(more than once) a groove in the casting near the external end of the bore.

There is another groove near the inside end of the bore(second through bore) in which a different type retaining ring goes in.

The shaft/bearings/gilmer pulley/clutch are inserted into the bore(s) from the outside until the inner bearing rests against the inner retaining ring.

The 'spiral lock' is then inserted in the 'external' end groove.

The part numbers of the rings are: (501621 - internal end) and (501299 - external end).

These part numbers are the ones in the current Mark V. I do not think they are different for a gilmer drive. Verify that b4 purchasing any.

OK...

This morning before I left for work I pulled out the headstock, Now that it is clean I can see the slot for the outer retaining ring. I think it was so full of c%&# that I couldn't see it before, also there must have been something in the slot that kept me from being able to press the shaft and bearings out that way. Now I need to order the missing retaining ring (and various other screws and such).

Thanks for your help

Micky,
Both my Mark VII and Mark V had spiral retainers for the inner and outer bearing retainers on the gilmer drive/polyv drive. I guess that there could be a snap ring or some other type of retainer used on the inner bore but on both of mine they used spiral type retainers. When I dismantled my Mark V gilmer assy I tapped it out to the inside of the casting after removing the spiral retainers as it was easier than pressing it out from inside the headstock casting as I would have had to use an extra long rod to press with.

Ok, I have taken everything pretty much apart and this is after the cleanup but before polishing. It will take a couple of posts to show everything so please bear with me.

This shows the headstock, quill and gilmer drive assembly. The quill and gilmer drive assembly have been reassembled after the bearings were checked and replaced.

here you can see the tailstock, headrest, tie bar, wheels and saw blades (that were solid rust before)

These are all just bare metal right now.

Here is a shot clearly showing the slot for the retaining ring I was unsure about.

and the inside

not shown but also done are the legs, and the tubes.

I also have quite a bit of shining things up to do.

That is it for tonight but I have a long weekend to work on things.

Those pics look like the same progress I am at right now except most of my polishing is complete. The castings look the same as mine after blasting. I too am looking at a long weekend of priming and painting. Then it will be bearings to order and then reassembly. Good luck looks like you are making good progress.

Outstanding looking work on the Shopsmiths. If any of you gentlemen feels the need to do more headstocks and/or Shopsmiths, I will be happy to pay postage both ways and supply you with headstocks and/or Shopsmith parts to clean and shine to satisfy your every need to do beautiful work. I will even pay for any supplies you may need. Thanks for the pictures.

You DO see the groove on the other end do you not?

I think JPG meant to call your attention to this:



Mine is identical to yours and had 2 spiral retainers inner and outer. The thing I think mine is missing is the screw and washer above the eccentric mounting position. I will have to investigate tomorrow?
