    Default Spindle taper I.D. ?

    Hi ,

    Looking at this spindle . The chap is not sure and all he says it is a quick change chuck. What type of spindle taper would it be ? MT maybe. It's a SIMA vertical milling machine from the 1950's or 60's. Thanks Mike

    That looks like a key less drill chuck, be hard to say what the taper is. A machine I had years ago had a chuck like that and it was threaded on similar to portable drill.
    BTW Thanks for the valves, I will put them to good use.

    You are going to have real trouble identifying it without seeing the tooling, jig borers have used some strange stuff
