sharpening a new bevel on a hand plane blade takes forever

Hello,

new on the forum and I have a question. My hand plane blades are sharpened at 25 degrees. In the workshop I give it a micro bevel of 30 degrees (by hand, not with the Tormek). After a while I need to put a new bevel on it (25 degrees). I do this with my Tormek T8 (normal stone).

A small Lee Nielson block plane blade took me more then 1,5 hours tonight. I tried everything; grinding the stone again (taking a bit of the stone with the jig), and making it coarse again and again with the grinding stone.

Really frustrating. So I could use some useful tips on this issue.

Thanks a lot in advance.
Rob

What wheel are you using? These use A2 cryo steels. If you are using the SG then they will glaze your wheel in no time and you will have to continually re-dress your wheel. If you are using diamond or CBN then you should require less time, but honestly you probably need to start of on about 80G. In any case the SG is Aluminium Oxide and too soft for the steel.
