Thanks again for all the advice. I decided the slow speed grinder with CBN wheel is the most efficient tool for what I need to do. I did learn a lot from you all on this forum!

General Tormek Questions / Re: Tormek for primary bevels
July 18, 2020, 02:06:56 PM
Thanks for all the advice gentlemen.
Ken, I did not know the packages were available piecemeal. I am going to look into this further. Regarding how long a "long time" is, it took me about 3 or 4 minutes to carefully regrind a plane iron on my friend's CBN wheel, and that was my first time doing so. So I would say anything approaching 10 minutes of actual grinding time is a "long time".
All my planes are Lie Nielsen or Stanley with thick Hock A2 irons. I have a few PMV11 tools also. I do need to regrind them back to 25 fairly regularly, as the 30 microbevel grows too large. Once they are reground to 25, I start over with my 27-30 microbevels.
I completely understand that I would be underutilizing the Tormek with my planned use. I just don't think the Tormek can match the speed or quality of edge I get on waterstones. It takes me less than 60 seconds to put a new edge on a plane iron on my Shapton 16000 stone. And that edge is the sharpest edge I can imagine creating. I have a permanent sharpening setup that is always on the bench. There is no setup, cleanup, etc. However, I don't want it to sound like I'm on a production line and every second counts. That couldn't be further from the truth. I just don't want to be standing at a machine for say 10-15 minutes vs the 3 or 4 minutes I experienced on a CBN wheel.
I was also considering an advantage for the Tormek is sharpening planer and jointer knives. I've read some horror stories about that on this forum and will need to research further. For those, I have a system in place using a Deulen jig, where I get all 3 knives shaving sharp in about 15 minutes. I don't know if the Tormek can help me there, I was just trying to justify adding the Tormek to the shop.
I think after all the research I've done, at this point I've learned that if I chose a Tormek, I would buy it piecemeal and use a CBN wheel on it. I'm hopeful that somebody can tell me how long it takes to do the actual grinding to change the angle on a plane iron with the standard Tormek wheel, because I do see the utility of being able to sharpen other things with the Tormek and would be willing to pay for that if grinding primary bevels is efficient on the standard wheel.
Men, thanks so much for all the advice so far!

General Tormek Questions / Re: Tormek for primary bevels

Thank you for your insight Jeff. It is very helpful.
Yes, it would be the same as sharpening. But I would need to grind quite a bit longer to essentially change the angle of the whole bevel. My main concern is, how long would the actual grinding take to do so?
I would leave the machine set at 25 degrees all the time

General Tormek Questions / Tormek for primary bevels
July 17, 2020, 04:07:37 PM
Howdy folks. Thanks for letting me join the forum.
I'm considering adding a Tormek to my shop. I'm a woodworker. I am looking at the Tormek for regrinding primary bevels on chisels and plane irons. I will not use it for actual honing. I am quite happy and efficient with honing on my waterstones. As you know, after a while, microbevels grow pretty large and the primary bevels needs to be reground. I have been doing this on a diamond plate but it is very slow going, and I don't want to put the wear on my diamond plate.
For this purpose only, primary bevels, I am trying to decide if the Tormek is a better machine than a slow speed grinder with an 80 grit CBN wheel.
After a lot of research I have the following concerns:
Even with the square edge jig, it can be fiddly to get a square edge on the Tormek
Tormek stone needs to be dressed, requiring a $100 tool on top of the kit
Some say the Tormek takes a very long time to regrind a primary bevel, say on a 2 3/8" wide plane iron
It seems like a very expensive overkill for use only to grind primary bevels
I have used a slow grinder with CBN wheel at a friend's shop to do a few primary bevels on plane irons as a test. I found it very easy to get a square edge, quickly, without burning the steel. Obviously some Kentucky windage and a light touch are required. To me it seems the only advantage to the Tormek for me would be that there is no chance of burning the steel.
I am asking for input on this. How long would it take on a Tormek to take a plane iron with a primary bevel ground at 30 and regrind that to 25? Does anybody have any advice for me regarding this decision? Thank you
