I'd like to add a 22.5 degree chamfer to thick (1.5"+) material. In the past I've done small chamfers on a router table with a chamfer bit. Unfortunately I can't seem to find any chamfer bits that are big enough to cut 1.5". What's a good way to go about this. I suppose it doesn't have to be exactly 22.5 degrees (for aesthetic purposes only), but I do want it repeatable and uniform (e.g. 20 degrees along the entire edge is fine). Is there a way to use a shorter router bit that I'm not seeing? Are there other tools for the job? Should I start with a short chamfer and start planing the material down?
The work piece is a 1.5" tall cylinder with outer diameter of 10" and inner diameter of 6" (e.g. 2" wall thickness). I'd like to chamfer both the inside and outside edges.
I decided to "cheat". A friend has a CNC router so I just ran it on that. Took forever and had a few gcode errors, but came out well enough.
