I've been trying to find the perfect tool to cup my popper mouths and am starting to get frustrated.
I tried using a router cove bit but that blasted thing tends to run off the plug on me and mar it all up.
Then I tried a spade bit, drilling that first then shaping it with a dremel. Very time comsuming.
Next, I tried to round out that spade bit but in the process, found by doing so, I removed the cutting surface. Now it just "Burns" its way through.
Anyone have a better solution? Maybe cutting down a "Step Drill"??? Maybe a better solution to rounding a spade bit??
I'm at a loss here!
Thanks!
