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 (https://www.amazon.com/Tormek-BGM100-Bench-Grinder-Sharpening/dp/B002O4A2NU/ref=cm_cr_arp_d_product_top?ie=UTF8)) 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 (https://www.amazon.com/Tormek-TOR-SE77-Advanced-Square-Edge/dp/B01GJXDG4I/ref=asc_df_B01GJXDG4I/?tag=hyprod-20&linkCode=df0&hvadid=309811990469&hvpos=1o1&hvnetw=g&hvrand=8529543395939913516&hvpone=&hvptwo=&hvqmt=&hvdev=t&hvdvcmdl=&hvlocint=&hvlocphy=9027821&hvtargid=pla-522060058926&psc=1))
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 (https://www.amazon.com/Sharpening-Tormek-WM-200-Master-Systems/dp/B00149L55K/ref=asc_df_B00149L55K/?tag=hyprod-20&linkCode=df0&hvadid=309807921328&hvpos=1o1&hvnetw=g&hvrand=4197111698943052277&hvpone=&hvptwo=&hvqmt=&hvdev=t&hvdvcmdl=&hvlocint=&hvlocphy=9027821&hvtargid=pla-381950188220&psc=1)) 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.
