Title: Stone!
Post by: LarsHansen on July 13, 2025, 12:20:00 PM
Hi.
Just "inherited" an old SuperGrind 1200 in pretty bad shape.
Reason tells me to trash it, but the challenge was too sweet...
Having crushed the stone, it became clear to me why the stone wobbled quite badly. At the top of the hole in the case, the plastic was melted. I intend to draw and 3D- print a patch including a new, enforced hole.
My main problem is to get the hole size and placement absolutely correct.
Would someone with a SG1200 be so kind as to help me with two measurements?
First one would be the correct diameter of the hole in the stone end of the case.
Secondly I would like to know thickness of the enforced ring around the hole.
Thanks very much.
Your's,
Lars

Lars,

Some of the 1200s had overheating problems which caused the openings to melt. I highly recommend that you email the closeup photo to Tormek support (support@tormek.se).
Please post your reply. We are curious.

The ring is actually the bearing and is made of nylon. There should be another one on the honing side which will be identical to the one on the grinding side. They come with the replacement shaft, which you will need if you repair it. If it were me I would be tempted to make an epoxy repair but a 3D printed part should be fine with 100% infill to make sure it is strong enough.

@ Ken:

But are you sure that they will find the possible shortcomings of an old model interesting?

@ John:
The odd thing is that as far as I can see, the holes on the honing and grinding sides aren't (or rather; haven't been) the same diameter!

Thanks for both your inputs.

Lars
That puzzles me
