Here is my set up, a £10 Lidl pillar drill stand and a small 12v drill. I've got these old style Romford wheels that need drilling to take crank pins. There are just shallow blind holes provided.

On the piece of wood, I have two more of the wheels, the small one is held done with a tiny screw but can still rotate.

So how do I hold it more firmly? Am I just too hopeful about the chances of such a set up drilling the crank pin holes accurately?

What sort of crank pin set up is best for upgrading this old Trinagchassis, drill and tap to fit current Markits screw in pins or will bits of wire do?

 

 

Smooth Vanilla is probably my CB handle.
