Joerg Hugel
I have enjoyed the email tips and have been able to make use of several of them. I recently looked at my pull-out collars that I use on the lathe and mill and thought maybe your readers would be interested in how I remove tools with tapered shafts from the spindle.
For my lathe and mill, I’ve made two collars from brass, as seen in the photo and drawing. To allow the internal thread to run to full depth, the collar is built up from two parts fit together with Loctite. Finally, the 4.2mm holes were drilled. I am located in Switzerland, but perhaps in other countries nuts are available to fit the Sherline’s spindle nose. This would greatly simplify the construction.
In use, the taper is removed by loosening the drawbar, about one turn, and then no hammer is applied. The collar is turned off from the headstock spindle with the assistance of two tommy bars, also seen in the photo. Adding knurled brass handles to the bars was a tip from a friend. I hope this tip helps someone out!
