I was reading about some of the home made grinders that have been built by members here. I came up with this idea. Keep in mind this was at 2 am(knee surgery has my sleep scedule all screwed up) my I dea is to use rollers off of a treadmill as I can get them for free. And run two or three belts on them at the same time so I could have diffrent grits. Sometime between then and now I had the thought that unless my belts are exactly the same length it won't work. So my question is how precice are the belts made? Is this a feasible idea? Or pain killer and lack of sleep induced nonsense
 
I'd say it won't work for a few reasons. Belts are not precise, and having three in a line would limit your lateral space.
 
I wasn't too conserned about space the treadmill rollers are like 2 feet long that would give me a good 10 inches oin either side. But if the belts are not made to precisly the same lenght it would only drive the smallest one
 
I for one would not want to feed my hand in a direction of a live belt while focusing my attention elsewhere. 5" blade + 5" Handle = 10" overall knife knife.

Just my 2 cents though.
 
How would you change belts? Such a long pulley would have to be attached at both ends, making changing belts very time consuming.
 
its just the meds man. been there ;) heavily medicated Ideas are rarely good lol
