Hi,
I am trying to finish my 2x72 belt sander project, but still fighting a few issues.
I have just about got all the belt wobble out of the system, which varies a bit between belts - I suppose part of it is the junk belts I have bought so far, not sure yet entirely.
At any rate there is still some side-side belt wobble you can see in this video;
Along with that, I have noticed running it at high speed for a while (> 2 minutes) the wheel shafts/axles (1/2" grade 8 bolts) get pretty warm to the touch. not so hot you can't touch them, but it makes me suspect the wobble has something to do with it ?
The rollers/wheels spin freely by hand and do not seems to be loose either - meaning no obvious excessive play.
The fit of the bearings to the shaft/bolts is fairly good? not a press fit and not loose/wobbly.
I bought the wheels and D-backing plate from OregonBladeMaker. they are the nylon ones.
Also, the bearings are on the smooth shaft of the bolts, not riding on any threaded portion.
I only have smaller woodworking belt sanders aside from this one which are very different - so I am not sure how "normal" this is.
But the heat to me means friction, and friction means wear, so I am assuming something "ain't right"
Any shared experience much appreciated !
