id be tempted to run it for a while, maybe the noisy bearing is a bit of crap thats snook into one during the trauma of the surgery you have done on it

It's alive!
Heated the angular contact bearing in oven, cooled the shaft and it dropped straight on.
Bit of a fiddle to get the rest together, but it went ok.
I've run it up to 3100rpm (24v) and it sounds fine. Slight noise from the bearing but I don't think that's significant.
I also measured the runout and it's less than 0.01mm.
Will post some more pics in a minute.

That makes two of us.
Make a walnut what?! But yeah, running it off two 12v 92Ah batteries for the moment. Not got a power supply which would supply anything like enough for this. Idling at 3100rpm it consumes 94w. 45w ish at 1500 rpm... that implies almost 200w just to spin the thing at full speed let alone cutting!

walnut whip ! .... shit joke.... sorry :)
94w
im getting on fine using 350w 12v on my 1700w motor, i dont think you will need to throw 6000w at yours if your using it on your routerLast edited by blackburn mark; 20-01-2011 at 08:28 PM.

I did the mount today, not the neatest of things I've made with the rotary table but it works:
Spinning...nice effect:
I ran the motor in for about 5 mins on 12v, soon got bored of that (I'll leave it running properly tomorrow). So I tried carefully grasping the motor body with some kitchen roll to protect my fingers - couldn't stall it, not even close . It merely drew 550w and about 53 amps. I'll have to think of a safer way of testing the power at higher voltages.
I think I'll stick with the batteries for now unless anyone can point me to a 50v PSU that can deliver a LOT of current. Maybe a few of those switching PSUs people have been using for steppers on eBay...Last edited by Jonathan; 22-01-2011 at 04:30 PM.
