Thanks for all the advice! I just wanted to clear a few things up. I`m adapting a straight shaft ER16 collet chuck as a spindle so it already has a hardened ground shaft when purchased. Fergus - I`m not choosing to use hardened steel, it just has a hardened steel shaft. I`m going to go with some bushes for two reasons. The chuck is coming from china and so it`ll take a month or so to arrive. I have purchased already some bushes from a UK supplier which will allow me to get on with making the assembly and then I can just slide in the collet chuck when it arrives. Pete, I would actually just go with cast iron bore as we originally discussed but for the reason of simply getting on with it, I`m going to use the bushes as they will arrive tomorrow. |
