Your gear train looks great, Michael!   :ThumbsUp: :popcorn:

I assume the clamps on the mill are to keep the spindle from turning during the broaching operation?  Interesting use of a mill!

Yes i was a liitle lazy and did it the Quick and dirty way. Some day i will build a clamp for the spindle, ...maybe ;D

Always great to see and feel it all go round and round, up and down as it should  :praise2:   :cheers:

I haven't seen broaching done on a Mill before - but as some here are doing the similar thing with Drill-Presses and Lathes - why not the Mill  ;D  and the result speaks for itself  :ThumbsUp:

Hi
did the rockers yesterday. The body is milled from an round stock of steel. The round part with the thread is silversoldered to the main part.

I decided to go this way instead of the adjustable pushrod.
The bore will get a brass/bronce bushing.

Still have to clean them.

Regards Michael
