I need a drilling jig made up from 5mm or greater steel, to bolt to my hubs and make redrilling them from 4x100 to 5x100 nice and foolproof on a decent pillar drill.
I've drawn up the template I need on autocad:
and when overlaid roughly over a picture of my hub shows no two holes interact too closely IMHO:
I can use polo disks on the front, and can swap VR6 rear stub axles and disk brakes over to convert the back, but I've not been able to find a compatible hub (late polo hubs have a larger driveshaft spline and different bearing setup) so it seems drilling the fronts is my only option (I don't have room for adapters with 17x7.5s!)
I'm also very open to any ideas on another way to get then drilled accurately using a pillar drill - I was thinking of bolting one of the wheels on and sharpening a wheel bolt into a centre punch and using that to locate the centre of the hole, but I'm worried it wouldn't be quite accurate enough.
