Since it is mother day, and I have oft been called a mother...... I treated myself to some shop time. Many moons back I bought this tool post grinder used and left for dead. The fella that owned it said that it went through a spell when it would shock him every time he used it and then it quit completely. It is an ID grinder set to run at 12K rippums. I didn't want an ID grinder that shocked me but for $100 I thought it might be worth the excitement. Heaven knows I need a good shock every now and again anyway. Found a wire just inside the case that was loose and the culprit of the previous fellas annxed. Once fixed, I didn't want an ID grinder, I wanted an OD grinder. Sticking the bigger grinding wheels on the shaft and spinning it at 12K is how you can put an eye out. Here is the hack. I reversed the two pulleys. By putting the biggun where the littlun goes and verse visa, now it spins at around 3K I ciphered. Then I made an arbor for a 3/8" ID wheels.
The fella threw in a couple of belts, a pulley and a couple of ID wheels but I needed a cover. TheMac wanted $165 for there stamped metal cover. I finally got around to buying a couple pieces of 3.5" 6061 AL and made my own.
Slides over the existing bearing housing just like the fancy one does, but only set me back $25.
I still need to knurl a set screw to keep it on the motor but that shouldn't give me too much of a fight.
