You need a centre finder. Around £10 on eBayBack to making more pins I need to drill 8mm holes through the dimeter of 25mm EN24T pins. I am trying to get the holes dead centre but only have a pillar drill has anyone made a Jig or have any tips on how to do it as I have 4 to start with.
Just tack 2 bits of box onto a plate together, with a gap in between to suit the pin.Thanks for the help I will have to order a pair of V blocks and clamps.
