Wachuko's Boyar-Schultz Six-Twelve Surface Grinder

[wachuko]

Those screw holes on the side of your chuck are for mounting a backstop rail onto the chuck. Everyone Ive ever seen is located on the column side of the grinder hence “backstop”. There is usually a side stop also which is located on the left side of chuck which is used to stop parts from getting flung off the chuck.
Both of the rails/stops should be ground in place on the grinder so they are in perfect alignment with both axis.

Thank you for the reminder. Those were attached to the vise. I just forgot to install them back. You can see them in the photos from when I got the machine. Here, take a look:

I will install them back in a little bit.

The point of Cadillac's comment is that the photo in reply #28 shows the operating rod on the right (correct), but the magnetic grid (top) plate is 180° out. The tapped holes for the end and back stops should be on the opposite edges. I see, in earlier photos, that both front and back edges are tapped.

Also, I think it's common practice to nearly fill the chuck interior with an oil. I would probably use mineral oil.

Yeah! Yeah! Olio... Fill the bungholio...

Both sides are tapped, correct.

If it needs to be filled with oil, I will take it apart again and use Loctite 574 to seal it. But there is no way to seal the lock/unlock mechanism area. Oil will leak out through there if filled beyond that level…

Then it may not be an oil filled magnet. I'm not sure what the oil actually does on a permanent magnet mechanism, anyway. Might serve as an insulator to constrain the field. The ones meant to be oil filled have bungs and seals.

I want to replace all the wiring...

All the tools were there... I could not find the manual for it... pretty sure it was in the garage as well, but it was a challenge moving around and reaching the cabinets/shelves on the wall...

You scored dude. In fact, you suck

That is why I do not think is an oiler... Can't find what it would lubricate. There is nothing underneath it. Here is the photo of where the table sits... you can see the center is open... unless it is just a pin that serves as a maximum/hard stop mechanism if you forget to set the stops on the front...

That might just be what it is for... if that is the case, then it should be something that I can make and replace... fingers crossed...

Interesting. The ways show wear at the ends which is typical. If you find a source for replacements let us know.
That's a sweet set up.

Besides lifetime lubrication of the moving parts, I think of the oil fill as a way to assuage the effects of any accumulation of flood coolant, commonly used on surface grinders.
If there isn't an O-ring or lip seal in the housing (at the operating screw) I would cut a groove and install an O-ring in the screw head where it passes through. YMMV

There was no indication this was ever used with coolant.

I will take better photos of that assembly… doubt I will be able to seal it.

So rather than doing more with this one… what would you guys recommend for a new magnetic chuck?? Budget friendly!!!

Ordered a 6"x16" cheap magnetic chuck for now... will research which one to buy later... I can always find use for this around the shop if it does not workout well for the surface grinder. Why this size? It is exactly the same footprint as the one on there right now. Figured I would install something with the same footprint, even if the surface grinder is only a 6"x12"
