Hello all
Need some advice about recently build grinder.
The belt is jumping from side to side, I don't think it is normal, what can be the reason, maybe somebody had the same problem and can point how to remedy it.
here is a short video

About the grinder. It is essentially a No Weld Grinder, built based on the drawings bought from BossDog, except that it is actually welded. The instrument arm is a swivel arm with 200 mm (8") bottom wheel and 70 mm (2 3/4") upper idler wheel and flat platen between them. The motor is 1,5 kW 1450 rpm (it is 4 pole motor but because we use here in Ukraine 50Hz it is closer to 1500 rpm not 1700 as in US with 60Hz), it is three phase but hooked to 220 V one phase through VFD.
