SG-200 Expected wear when restoring tools.

[Alexandros]

Hello!
Happy to make my first post here.
I have a T4 for about 7 months.
Mainly I use it for woodworking tools (axes, knives, drawknives, planes and gouges).
Since I had in my possession many old tools I used the T4 to regrind and re-profile many old neglected or damaged tools.
4 axes, 2 drawknives, 3 planes, ~25 gouges, ~10 mora knives plus some more light sharpening of knives during those months.
I realized that the diameter of my SG stone is now 175mm.
Does this wear seem more than expected?
I realize it is a general question but keeps bothering me... Maybe I am putting too much force and wear the wheel more than I should?

Welcome to the forum, Alexandros.

You did not put too much force on your grinding wheel. The amount of wheel wear you have experienced is not unusual. As you say, you have reground and reprofiled many old neglected or damaged tools. This involves considerably more grinding than sharpening tools which are merely dull. You will find that the next time you resharpen these tools, assuming they are just no longer very sharp and being sharpened at the same profile, sharpening will be much quicker and with considerably less wheel wear.

If you do not already have a TT-50 Truing Tool, I recommend that you purchase one, (The current model is much improved.) Take light cuts with it and use it frequently. This actually causes less wheel wear than infrequent, heavy truing.

One of Tormek's expert trainers told me that the learning sharpening causes more wear to the grinding wheel than subsequent sharpening. Not only are the tools generally sharper to begin with, the skills of the person doing the sharpening are more refined. Congratulations, you have put in the hard work. Youshould have smooth sailing ahead.

Keep us posted.

Thank you for your reply Ken!

I realize and have already experienced the next sharpening and was as you say much faster and much easier.
After the regrinding of my old gouges the uneven wear was really obvious, I got a cheap diamond wheel dresser (t-bar style) and to be honest it did a good job (I realize not as perfect and controllable as the TT-50 would do, some day hopefully I get my hands on one).

I do feel like that will be the case, just after the measuring of my wheel I got a bit anxious maybe something was going more wrong than I thought.

Hopefully you are right and I get a smooth sailing!
