IT'S KICKING!!!!!

I now have 3-axis movements and a spinny spindle - yay!
The problem was the fan motor overloading, causing a breaker trip. I didn't recognise it as a breaker, hence not pressing it sooner.... pressed it, everything started up then clonk, off it went again. Disconnected the fan motor, and then it kicked in and stayed in.
Andrew - It doesn't seem to need an air supply after all. I wonder if it used to be connected to an auto toolchanger, I believe they are air powered?
Dave - Number will be in a PM soon, thanks for the kind offer

So.... next issue - the magnetic spindle brake doesn't work properly... it consists of an electromagnet, a slightly domed metal disk (I assume a magnet enhancer), a clutch which is supposed to go up & down, and a brake disc. The problem is, when assembled as per getting the machine, other than emitting a faint clonk, nothing much happened. I am able to assemble the parts in a configuration which causes the spindle brake to work (albeit weakly), but bass ackwards - i.e. applying power turns the brake on. It should be the other way around...
Can anyone who happens to have a manual

tell me if there's any info about the magnetic spindle brake, e.g. how it goes together? I can at least trial run the machine without the brake, what I'm not sure of is whether it's getting all the volts it should be (~27v) and therefore is a bit on the weak side.
But, hey, IT WORKS! Thank goodness for that!
