inside threads of Robur adjustment collar

[sutono]

Has anyone ever replaced the INSIDE threads on the adjustment collar on a Robur. Esi says the part does not exist, and that I should use my grinder for parts.

Uh...

HUH?

What do you mean "inside threads?" You mean the threading on the grinder body?

I'm assuming you did some bad cross-threading, and you need new threading?

Ouch.

I just had a look at a Super Jolly, fwiw. If the Robur is constructed similarly, it appears the grind chamber and the burr carrier mounting threads are part of the body casting, and not a separate part.

Shop around for a blowed up Robur with a good housing.

Why could you not try to re-tap it? Could you not repair the damage (assuming you did not strip the whole thing out) by running a tool through it?

That would be one honkin' huge tap.

You are a genius! We ordered the tool today, and are looking forward to creating a new and different $2000 paper weight, with slightly altered threading : ) They have metric!

Niko,

Yup.
