Is that without a pilot hole? i.e. removing a 10mm diameter cylinder? If so that requires roughly 310W (at 'reccomended' rpm). What rpm did you use?
haha! no chance! im using an old pc power supply at the moment thats probably only putting out 300w on 12v, besides that i cant get the levarage to drill 10mm in one go... im using one of my linear slides up-ended with a live centre attached just to guid me in straight :)

if i push the motor hard the pc power supply trips out... iv got a 12v 30a supply and two 12v 45a power supplies but iv not got around to sorting them out and as im getting by with the one im using iv percivered with it... the large motor dosnt get warm at all... the ESP worries me now and again, its a turnigy 85a so im thinking the heat is normal

Yeah, I bought it to put on my bike, but that's not happened. I'm thinking of replacing the pathetic motor on my sieg C3 lathe with it. I still think it'd be good on my router for aluminium
im thinking of buying another of the larger motors i have to run my cowels 90 lathe, it knocking on a bit now and the motor bearings are a tad noisy

Some nice research there Jonathan!!!!!!!! im going to have to pick your brain when iv absorbed what you have up to now... sounds like your nearly there, it would be a winner if it can be sorted... im still on the mechanical side of things at the moment but another week or so and i should be mounting my steppers and wiring the whole thing up

iv built a low profile pc out of my scrap box that im fitting into the base, im just hoping the hard drive can handle a bit of vibration
