New spindle idea for my machine - DC 1HP

[John S]

Robin,


Swapped the bearings in the spindle last night which made an improvement but still got a vibration/resonance problem which looks like is coming from the toothed belt, tried different belt tensions which altered when the vibration came in. After a couple of phone calls I think it could be to do with the small amount of 'wrap' i have on the smaller pulley, will be making up an idler pulley to run against the back of the belt to push the belt further round the small pulley.

Should have used a Polyvee belt

I know your right and you know you are right.....

Still got the tool to make them and the 2 sample pulleys that I borrowed from you! Where did you say to get the belts from?...... smart arse.
