Hi Peter,
Many thanks for your prompt reply. Closer reading of the works MZ manual calls for the bush in first, then references a tapered mandrel, to gradually open the bush up tp the diameter of the sleeve.mounted to it, which makes sense for those with a lathe or the will to pay for one to be made up. In the meantime I’ll persevere and give your method a go. I have a small lever press which should help.
Fingers crossed….
