Here are several pics of my new PM 2x72 belt grinder. Well, at least it is the correct colors, & uses the motor from my PM 1236 lathe.
Anyway, it was a lot of fun to construct, & it still needs some tweaking; but it runs and cuts great. (Video at the end of the post.)
Some info on the parts used:
1. The front end, consisting of the large piece with the 2 rollers, the platen, & the black tracking roller were purchased from OregonBladeMakers on EBay.
2. The Blue pieces were scrap 2 inch box tubing.
3. The White pieces & the shiny pieces were Stainless from the local metal yard. Side note: The small tubing only required small amounts of grinding (milling) to fit inside the larger pieces. There is NO seam inside the tubing.
4. The switch box & switch was purchased at my local Ace.
5. The large pulley on the motor was also purchased at the local metal yard. It is 7.5 inches in diameter. With the placarded RPM (1410) of the motor, that results in approximately 2700 SFM on the belts. (A bit less than desired.)
6. The motor was "re-purposed" from my PM 1236 lathe.
All the welding was done with TIG.
Here is a link that provided the inspiration and basis for this grinder.

I have not tallied up the cost; however, I can estimate that the purchased items came to the ballpark of $250 (not counting belts).
OK, enough yammering. Here are the pics & video.
