Making a shaft with a collar... question
If you were in my shoes.. what would you do?
A shaft is needed for a machine, 1.5" dia, but with a collar at the middle of it. The collar needs to be about 3" od and about 1/2" thick. Access to machining equipment is limited. No mill, and an abused lathe that is too old with only basic basic tooling. Budget being the eternal issue, I am planning on machining the collar out of mild steel and carefully TIG welding it into the shaft, and then re turning it to cut away excess weld and to make sure it's not crooked as hell. Has anyone tried this and failed because the shaft warped excessively? suggestions please... I would attempt to machine the shaft from larger stock, except it would be a first lesson on super close tolerances on the 1.5" as well as the nice finish. overall length of shaft is perhaps 12". Thanks for the advice - Loren |
