I have a 1/2" and 1/4" collet for my PRT96 with Porter Cable router. I want to start doing some small 3D work and have some 1/8" diameter ball nose cutters but where can I get a 1/8" collet? I have looked on ShopBot WEB and looked on EBay and even a Google search but find nothing. I could make an adaptor to fit into my 1/4" collet but I would rather have a true running 1/8" collet.
