I asked once before and broaching was suggested but that is no good for wood or plastic.
Looking at the vast array of power tools I was expecting to see a reciprocating file but I have yet to see one.
Any thoughts on how to fabricate a tool that would provide a solution to this need.

Broaching does work for plastic's particularly types like Delrin (Acetal) it broaches with a simple tool - would post details if you need piccys - I suggest you start a thread somewhere, However having said that it can be very fiddly to program - you'd basicly have to hand-code the broaching cycles - it's much easier to broach right through the material - to broach an internal 'blind' courner' is real tricky!!
I'm not much of a 'wood-man' but you've got the grain to contend with and so - very difficult.
you'll have to post details of what you propose to broach - how thick - what material - are there small details...
