Nice spindle design!
Thanks for posting!

I have been searching for a design like this for some time. This could be adapted for use as a milling spindle for a small lathe. I have been using a Unimat cartridge spindle but it is limited in vertical travel to about 1”. I want to at least double that to allow for deeper drilling.

Thanks for the comments! This spindle gives me a vertical travel of aprox. 50mm (2").

Steve,
What machine do you use it with?

Steve,
What machine do you use it with?

I did put it in a 350W benchdrill from the brand Ferm. Combined with a selfmade milling table it will allow me to do light-duty milling work. I am going to do some small adjustments to make it work with a 500W motor.

Nice work Steve.
I too have very basic bench drill (RECORD) which I inherited, I have made a few mods for milling non ferrous metals with an old XY table. The main limitations were the Jacobs taper chuck mounting and the flimsy tubular column. I replaced the column with a solid one and after removing the chuck drilled and reamed the end to take ¼ end mills. The next problem was being able to lower the head down to the table for rigidity, easily fixed by cutting away part of the belt guard and fitting a stop collar to the column. Then a fine feed was made for the quill together with a quill lock.
I mainly use it for coordinate drilling but a decent quill as your design would improve matters and thanks for the drawings.
