Doest anyone know what nut I need to buy to replace the plastic nut on the T4

[jbaker]

Hi,
I have a T4 and a few different stone grits which mean I change the stone several times each time I sharpen anything.
The plastic nut is not holding up too well and I soon I will need to find a new one.

I could buy a whole shaft which as I only need a nut is an expensive nut.

Does anyone know exactly what nut  I need to find in a local engineering supplier ?

I know is a left thread. I guessed its an m12. That nearly fits but not quite.

Thank you if you can help.
Best Wishes
JB

Welcome to the forum,Jess.

This is the part you need:

Any authorized Tormek dealer should be able to order it for you; however, Advanced Machinery will have it in stock. I remove my grinding wheels frequently, and swapped the plastic nut for the steel nut which comes with the T8. The left hand thread is the same.
While you are ordering, I would also order the locking knob for the honing wheel. (This is also standard with the T8, but is the same thread.) This was originally called the "quick connect". Hereis a link:

I have happily used these two upgrades with my T4 for many years. It's a great machine, and better with these two upgrades.
