Fear of heat- not an issue

Bill Tindall, E.Tn.
It seems that the main reason some are willing to spend hundreds of dollars to be able to hollow grind a tool, and not very hollow on a 10" wheel, is to avoid heating the tool excessively. For those that don't have a several hundred dollar grinder budget there is an alternative.

Yesterday I was getting a #2 plane ready for sale. The blade was out of square and not hollow ground. The fastest way to correct that problem and establish a hollow was on the grinder. 3600 rpm, 120 grit wheel of the proper specification. 7- 1 second passes passes across the crowned wheel and DONE. Less than a minute elapsed time. ( a more resistant blade like V11 would have taken 2-3 times as many 1 second passes.)

I have modest hand too skills. Yet, I can grind anything with this set up. I have taught numerous people in the club to grind on this set up and they were all successfully grinding Stanley blades in short order. Ditto for Smith posting above.

Anyone not successful has not followed directions- crowned soft bond wheel(ideally pink), sweeping light passes. The "white" wheel that came on your grinder is not soft enough. Norton 3X wheels are not soft enough. The LV white wheel is barely soft enough. You will need to order the proper wheel from a tool supply place- Travers, MSC, etc. But for 1/20 the price you will be successful.

The problem I used to have and I think many others have is the plane or chisel is thrust straight into a flat wheel, thereby heating the 3/4" of bevel all at once. The proper technique is to use sweeping passes on a crowed wheel. 1/2" wheel is wide enough.

My friend's Tormek, that otherwise now sits unused, was exceptional for sharpening sheep shears.

These things come with a silicon carbide wheel?! Why? It is well known that silicon carbide crushes easily to a finer particle size. It is therefore not a good abrasive for hard tool steels like we are grinding.
