My son is looking for chuck for his lathe (or an adapter). It has a 2.5 millimetre pitch and the bolt which the chuck would fit onto is
18 millimetres ................. any ideas ? Sorry if this makes little sense but I have no knowledge of this and have not seen the item as my lad lives in the States. The brand is Cummins which is just a label so no spares back-up. It is a budget item so when it goes wrong you buy a new one but a chuck would be very useful. I though that as it is metric, there might be something available over here.TIA Phian
