Hey Skip, :) post some pics of your setup in this thread please. The whole idea is to give people some ideas on how they can get setup.
If you have 3" of shaft on each side that would be workable but very tight.
Hey Tim :)
My primary use is for sanding razors, not buffing. That requires a speed much slower than 1750. More like 400-800 rpm . I do not expect any problem with wobble at the slower speeds and using small wheels of 1.5" to 3" max.
The reason for ~ 8" is for clearance of the entire blade. Check out Charlies video to see the advantage of clearance. You won't be pushing the tail of the razor into the motor/ bearings/chuck depending on the specific setup.
Randy asked me to post some pictures of my low tech buffer. I bought the pulley driven grinder at a garage sale for $2, the motor was free, and I used about $15 worth of miscellanious to complete the unit. Since buffing wheel are thinner than grinding wheels, I was able to gain some extra space by adding 1/2 copper pipe spacers. This gives me enough room to buff virtually any size knife or razor. Posted FYI.

Yup! :) I have an arbor/shaft almost identical to that. It has an old 1750 RPM 1/4 HP motor that runs like a champ. The downside is that I cannot reduce the speed to 400-800 range nor can I use a 1.75" diameter sanding wheel that will fit into the hollow of a 9/16 blade. If I do mount that size of wheel on that arbor I will most likely be knocking the tang into the arbor ( assuming I get the speed down some way). For me this is all about sanding/grinding to remove pitting. It is not about buffing.
Thanks for posting your pics! They will help some new guys for sure. :)
Hey Tim :)
Yes, in some cases I will be leaving the scales on but even with them taken off the length of the blade is ~6". Then add on my fat fingers and a little bit for slop and 8" is used up kinda fast. Especially if your using the wheel on the right side and trying to sand/buff the face of the blade. I could get around this if I used the same grit wheel on the left side of the shaft but then I have to duplicate wheels.
