There's metalwork and woodwork forum areas, what about plasticwork?

Where's the best place to discuss Plastic?

I was hoping for advice on spindle power. For my upcoming 6040 purchase I couldn't decide between 800W and 1500W spindle. Obviously I'd prefer 1500W.

However I've put in an ebay offer for a 800W machine now because the asking price for the 1500W ones are about £250 more. The 800W machine comes with a 1500W inverter, and the 1500W spindles can be had for £85. So it looks cheaper to do the upgrade myself if more power is needed. All I'll have to make is a new spindle clamp. Delrin OK for that ?
