I got a weird surfboard related project I'm working on.
It's a long story but I really just need to cut slots into the rail of a blank that I am working on.
The slots need to be 5/16" wide by about 3" long and go all the way through the blank.
My goal is to add short stringers...
Anyway, I am looking for a router bit that's somewhere in the neighborhood of 5/16" diameter with longer than a 1" cutting depth.
I know they have those ones that look like drillbits that they use in CNC machines for cutting foam.
But, they are expensive!
Anybody have an old one laying around?
Alternatively, would a drill bit work in a trim router if I get a router speed control and turn it WAY down?
Any other ideas?
I *could* use my current bit and just do a double pass...
