Machining a double D

[mekanik]

Hi Dean
It might be possible to use a wobble/rotary broach to do this but the only type i have seen leave a symetrical hole ie hexagon internal spline ect but the holders l can be self made but you would have to get the tool made as the the usual silver steel tool(hobyist aproach) would probably not fair to well with Titanium.
Just a thought but if you are running batches of 100 you need to get tooled up and a wobble broach setup can be done in the lathe or mill.
Regards
Mike

Cheers Mike I have seen this been done just but not seen or found any double D's clearly can be made to order, also not sure on what depth these allow. But is another option to consider and has you say if tooled up then this would make is post in doing it all myself and all on the mill.
