Cheers, slow progress but progress none the less!

I'm a bit worried that my bearings in the spindle are on the way out, which is a bummer as its not that old. Can't feel any play but just towards the end of the second piece it makes some very unpleasant noises when cutting until you tweak the rpm out of what I assume is a resonance band. Wasn't doing it before.... I might have to delay the purchase of more materials next month to put the money into a new spindle instead and I had just spent hours getting the tram perfect!

Looking at this combo on ebay at the moment, I guess I could do with a new VFD either for the new machine or to sell with the old one. http://www.ebay.co.uk/itm/260626018545

I bought my spindle from the same seller. Note that the spindle earth is not connected, at least in mine it was not. Also, I went for a quality VFD instead of buying that Hy. I am using Modbus and the Hy, while they call it Modbus, does not talk Modbus. If I were you, I'd buy the motor, but would get a different VFD, something of a real brand.

Here is a bunch of 2.2kW VFD sold by the same shop I bought mine from.
