Ideas: router milling jig for brass and bronze

Hey all,

Anyone used their router for milling brass and/or bronze? I can get my parts pretty close size/shape-wise with my bandsaw and belt grinder. Would like to build a "simple" jig for machining the last bit... exactly. Ideas/pictures...?

I see the issue as that of speeds: The maximum speed for peripheral miling of brass is AFAIK 350 sfm. You can increase it by 35% if you use Titanium Carbonitride coated end-mills. This would give you about 15,000 rpm for a 1/8" end-mill. Most routers go down to 8,000 rpm, so this is about the largest end-mill one could use and even then it is being pushed to the max.

For me, I do not see the practicality of such approach.
