Hello all, This KMG-style grinder, with the tracking wheel in the normal position on top, was no good trying to run in reverse. The belt just wouldn't track right. So I took off the tracking arm, drilled a new hole down low, put the thing down flipped it and reversed it, and viola! Works like a charm. :] When grinding a large titanium alloy blade, it's hard to avoid launching very hot sparks, and igniting combustible titanium dust into a miniature magnesium inferno. If you want to grind lengthwise, then the dust comes right at you. It's a bad idea to be getting covered in ti dust and launching the sparks on yourself. Wet grinding helps, but can lull you into a false sense of security. Hence, I run my grinder backwards, which is one of the reasons I used a two-wheel grinder for so long. This new setup, with VFD, should make for a nice improvement in grinding quality over the old two-wheeler! A titanium sword grinding machine.
