Hi, I put a new wheel on my home built grinder then took it off to check on why it wobbled. when I put it back on the motor would not turn the wheels. I totally loosened the wheels and it works fine, also with out the wheels. I put the new wheel on several days ago and it worked fine. What am I doing wrong. here are some pics of the grinder

Is it possible that when tightening the wheels, the middle section is pinched together, and the wheels cant turn freely?

Take one wheel off, then tighten the other wheel

if it runs, then thats your problem

p.s.-can’t see the assembly real well, can i have a pic with some more light on the wheel area?

In your second pic, it looks like your belt is way out of line. That’s probably not the source of your issue but it’s going to cause some inefficiency in your set up and your going to chew through belts faster than normal.

If the belt’s too tight it can bog your motor down too much for it to spin

Karda, what is the HP rating on the motor? If it’s a 1/4 hp, combined with the belt misalignment, too tight a belt, and those large heavy wheels, it just might be too much for the motor.

I know you stated it wasn’t too tight. What is your guide for achieving proper belt tension?

So you know the belt is out of alignment, what’s your excuse for not fixing it? ...... Jerry (in Tucson)

Well, since it’s a ‘homemade’ grinder, nobody should know more about it than you – unless you weren’t the one who made it. From the description, it sounds like the grinding wheel is contacting the housing – perhaps just missing a spacer or improperly placed stop collar. Would have to have a better picture to give any real advice.

Cheers,
Brad

the belt wasn’t fixed because I new it would be a major undertaking to fix it. I just spent a half hr tring to pull the pully, can’t get it. I don’t even think there is room for a wheel puller. there is some kind of collar behind the pully. I moved the motor but didn’t do much good but I can move the arbor over a little. The wheels turn, I moved the shaft and got the stop collar to tight moved it over works fine now

OK, I took a nap. Yep, I still feel the same. No excuse not to fix things that are not right. They can lead to problems and more costs later. . That’s why you fix them now…..... Jerry (in Tucson)
