I've posted a couple times lately with questions, so I thought it time to share where I've gotten to on installing the Tormek BGM100 (LINK) on my Rikon slow speed grinder. This rig is intended for Turners, but when I saw Derek Cohen was using it for flat tools too, I was encouraged to try the same. I want to stress that while this is a workable prototype so far, I plan to work with it a while before I finalize the design (and pretty it up).
1. I preferred to leave the guard on the wheel based on answers I got to questions here. But in the stock position, the guard interfered with the SE77 Square Edge Jig (LINK)
2. So I drilled 3 new holes in the guard to let me rotate it about 60* and devised a crude mount ro let me work from the top, sort of like a "real" Tormek without the water. The mount shown is crude right now - I'll pretty it up after I've used it long enough to be sure I haven't missed something. But Ixm hopeful because I have ground various lengths of chisels and plane irons, ranging from 15* to 35* and so far it has handled all cases. (You cant see it in the pics, but under the knobs I have slotted the wood so I have another degree of freedom to adjust the guide.)
3. The Tormek Anglemaster (LINK) was giving me fits, as you saw from last night's post. That thing just isn't very accurate at low bevel angles. For future reference, here's the corrections I have to use with my 200mm CBN wheel:
* To get a 15* bevel, set the WM200 to 11*
* To get a 20 bevel, set the WM200 to 16*
* To get a 25* bevel, set the WM200 to 25*
* To get a 30* bevel, set the WM200 to 30*
* To get a 35* bevel, set the WM200 to 35*
Here are a couple pics to give you ideas.
