Huh, hadn't thought of using my orbital sander. Seemed unruly, but doesn't mean I can't start with it and finish by hand. I usually just use my grinder for the cutting wheel, but I will look for videos on grinding a bevel.
That bubble jig looks cool. Unfortunately, his site says he can't get materials right now. And is out of stock.
I figured that was the answer. I do use a 4x36, but it's a cheapo machine. I use it a lot out of necessity, but I have to be patient with it to avoid stalling the motor.
Great advice all around.
