General Tormek Questions / T4 200mm honing wheel
September 11, 2022, 09:32:24 PM
Hello.
I simply cannot get good results using the supplied honing wheel.
I have made a wooden wheel with leather surface 200mm diameter and 40mm wide.
It has a great deal of promise as I keep the knives in the jig, change to this wheel and hone.
It is very much better than using the original wheel.
But!
I very much would like to purchase a 200mm fully circular wobble free leather or felt or whatever wheel, but cannot find anything.
It would be excellent if Tormek would produce a 200mm honing wheel, but in the meantime, has anyone any ideas?
Apologies!
I should have said a 200mm wheel to fit in place of the supplied one (at that end of the machine)

Hand Tool Woodworking / CBN WHEEL & story
September 30, 2021, 04:20:51 PM
Hello everyone, I would be very interested in your comments on this:-
I had an old 8" bench grinder, it needed a new stone & I ended up buying a 180 GRIT CBN.
Mainly my research was by watching YouTube's, Stumpy Nubs & Rob Cosman etc
After turning bushes for it & mounting it on the 2880 rpm grinder, two things rapidly occurred to me.
1, my grinder shaft was probably not straight
And
2  it took 11 minutes 17 seconds to stop.
I stripped it down & renewed the bearings, tried it again, re-mounted my original grind stone & gave the machine away.
This left me with an 8" CBN wheel.
I tried to buy a 1440 rpm bench grinder, but these days in the UK, after Brexit and COVID, there are none to be had.
So.
I bought a Tormek T4
And am very very pleased with it.
I find the Tormek wet wheel very nice indeed for exactly what's it is supposed to be for, and when my CBN is mounted, that one is extremely good at much faster material removal than the Tormek wheel.
The CBN also is superb at sharpening metal working lathe tools both HSS and tungsten carbide. (I made a quite crude tool rest for grinding the lathe tools)
I know Tormek do not advise the use of CBN, preferring diamond, but as you see, I was painted into a corner and found a pretty decent solution I think?
Anyway, does anyone have any advice on this?
I use Hone Rite gold in the water for all grinding & am hoping that won't destroy the beautiful Tormek stone.
I could also mention I always hone finish my cutting tools on 8000 grit whetstones by hand, I can't for the life of me get any feeling for the honing wheel on the T4!
Regards
Peter
