Hello,

With my Tormek T8 I received the standard SG-250 super-grind.
I've already ground three VERITAS PM-V11 chisels by veritas up to 1 inch with success.
Yesterday I've put a new 25 degrees primary bevel on a pm-v11 jack plane
2 1/4 wide and it took me ages. The stone had just been trued up with coarse serrations
but it kept glazing. (Maybe the pm-v11 being a powder metal is the issue). As I was approaching to the very edge it seemed to take forever. I think that for these wide hard blades and full edge restoration I have to true up again the stone halfway

Do you think that the black stone would be quicker? SB-250
I wouldn't try diamonds as my diamond benchstones struggle with pm-v11

Thank you

Hello,

I have a couple of long shipwright and timberframing chisels. Awesome chisels made in Petrograd though.
I'm a bit concerned about if using the original setup or if I have to buy the US-430 Extended Universal Support to move the se-77 jig away from the wheel and balance it better so that the fulcrum would be around 15 or more cm from the wheel. My other concern is of what is the maximum blade thickness that the jig could accomodate. Otherwise could I just lay the back of the chisel directly on the support rod
and slide it freehand? Like I would do on a normal grinder

Anyway these are the chisels. The middle of the blade is a bit rough on the back because it has the hammer textures. But still parallel. I might scratch the rod though. Maybe I can find a little copper pipe to slide on it and stop with the se-77 lateral stop knobs.

First has a blade and overall length of 300mm - 550mm
Second has a blade and overall length of 350mm - 480mm

Hello

In the HB-10 manual and in some videos is explained
that the side of a SG-250 (Tormek T8) could be used
to flatten the face of a chisel or plane blade.

My concern is that if I start to do it as an habit I would eventually affect
the width of the stone that is 2 inches wide out of the factory

Thank you, Haitham Jaber, Rome
