Why is it that no matter how careful i am measuring and marking out i allways end up having to oval a slack hand full of holes, each time i start a new project i think " this is it now, im on it, iv learned by my mistakes and THIS time its all gona work like a bobby dazzler"...........Bollocks!!! there must be a tare in the space time continuum cause im buggard if its me! :)

anyway, its starting to look like my drawing now, i drilled all the holes using my larger diy spindle and my Y axis up-ended as a sort of pillar drill (didnt want to be swinging around with a hand held)

im pretty sure ill have to oval a couple more holes when it comes to trueing it up but iv got a sh*t load to do before its finished and i dont want to think about it :)

(anyone thinking of useing helli mode on a RC speed controller, dont bother, it dosnt seem to hold revs any better than standard and it has a slow wind up to speed so every time you jam your drill you have to pause for it to catch up)
