Turning your own out of solid stock is doable, but takes some skill and tooling. You would be best to cut the spindle thread, mount the stock and then proceed to cut the collet taper and ER nut thread which is metric. You also need someway to hold the chuck when unding the ER nut, I machine sume wrench flats into my ER40 chuck that I made. Alternatively you could get a back plate, mount it and then machine a registration step so you can use a set-tru mount ER chuck similar to what Alan did on his PM-1340GT.
