Re: source needed - steel router bit v-groove

That is a very interesting approach. I realized that I have this old Craftsman (sorry for the spelling) moulding head that holds three blades/knives. It would work, in theory -- it is would cut deep enough, unlike a standard setup on a bench shaper. Maybe I could have knives made for it rather than altering the router bit. Do I look for "Tool Grinders" in the Yellow Pages? Or, does anyone know of an on-line or mail order source for such a thing? I have detailed CAD/dxf drawings of profile.

Thanks.

No luck in the Yellw Pages but having some luck at Thomas Register. I think. Not

100% sure if the companies I am finding are right, but I'll check on Monday. Thanks.

BTW, I also found a company that makes "roughers" and burrs, or some such.

to rough-up surfaces, and they have 60 deg bits, so I could use the standard router bit and then the rougher. That is now Plan B.

How would a molding head work for making a v-groove with lines it? If the groove is just stepped, that would work. But if you want a v-groove with raised lines (or even cut in lines), a molding head won't be able to do that since it doesn't move in the same direction as the material.

the standard

Of course, you are correct. But my original idea -- not actually stated here -- was to approximate many steps. A rough surface would be good enough for the prototype, and a $14 router bit seemed a good way to go. Anyway, I sort of backed into a solution. Thanks.
