The tool being used in the first part of this video (link below) is an Acme Post Grinder. It seems a DIY version of this could be made. However, I am not exactly sure how one would do it. Bench grinder stripped and just mount the wheels?

I know someone here must have an idea or has already done something like this. Would love to know how or see some pictures.

Wow! Looks like a very expensive and industrial strength machine to me. Not only that, but the wheel itself looks very expensive and tailored to sharpening. The gentleman with 25-30 years of experience makes something almost impossible look easy.

I don't think you will be able to match any of those things on the cheap.
 
Well I would not need it to be that heavy duty. Just something to rotate the wheels. I even though a Skil Saw stripped of everything but the motor may work.
 
That was addicting.... I watched all the videos. It's amazing how simple that they make it look.

Maybe it would help if we knew what it is you are trying to accomplish. What are you sharpening? I've never heard the term "post grinder" before. What is a post grinder, and how is it normally used?

I would like to do what he is doing. It looks like a fun tool to have and learn different sharpening techniques. However a used Acme post is $1500 plus. I just think for my "playing" one could be made more inexpensively.

I do not really have a specific task in mind.
 
I don't know about that. It seems like a pretty silly and dangerous operation, IMHO. I seriously doubt that the shaft on a $1500 industrial machine will match the 5/8" arbor of a circular saw. You could just use a $5 abrasive metal cutting blade on an overtuned saw, but I've worked with power equipment almost my whole life, and I'm telling you, that's not a good idea. There is a very good reason the real tool is that expensive, big, and heavy.
