Drill spindle for boring bar holder

[T. J.]

I am in need of a tool post drill spindle for an upcoming project. I decided to build one that could be held in my boring bar holder, since I could easily build it with just my lathe (my mill is not yet operational). I had the small Jacobs drill chuck on hand. The bronze bearings were what I could get at Tractor Supply.





Incidentally, this was my first successful attempt at single point thread cutting


When it was mostly done, I used it to drill the set screw hole for the locking collar. It worked well!

Nice job! now I have to add that to the list of things to do.

Did you add a oil hole for the bearings ? Even sintered bronze bearings need oil.

No I didn't. That's a good idea though. I did oil it prior to assembly.

I should make one of them too. I have a small chuck and spindle that aren't being used for anything.
Thanks for the idea.
