Diy Brushless Spindle

[Jonathan]

Well I was thinking of either buying one of these http://www.rdgtools.co.uk/acatalog/PROTRACTORS_ETC.html or drawing the bit in CAD, printing it out and sticking it on and centre punching the holes before drilling on the pillar drill, think I'll go the first way as the second seems a bit crude!!

No need to buy those... as Mark said all you need is dividers. Scribe a circle, or lightly touch the lathe tool to it whilst in the lathe to make a circle then use dividers to divide that circle equally - centre punch then a quick swing on the pillar drill. Equally nothing wrong with printing out a template and sticking it on - printers are pretty accurate.

If you've got access to a milling machine then just put it in the vice, center drill (or spot drill) in mill and mark out the holes with that. Zero the X/Y dials in the center, noting in what direction you zeroed them so you can compensate for the backlash by always turning to that point in the same direction. Move it the correct distance using CAD program or simple trig to find the distances.

There's many more ways to do it sufficiently accurately without buying anything.
