I am fairly new to woodworking, I have done carpenter type work as a
hobby for a while. I got a new plunge router for Xmas and have been
having fun with it. Today I needed to cut 3 disks out of 1.5 inch
thick lumber. I used a 2 inch straight cut bit with the Jasper circle
cutting jig. I made 3 passes and had my 5 inch disk but I also had
smoldering wood. I had it hooked to my vacuum cleaner rather than my
dust collector so I wasn't too worried. I have been wanting to build
a router table but now am worried about hooking up to my dust
collector.

What did I do wrong. Router too fast? Wrong bit?? Needed four or
five passes?

Thanks Steve


In a blind cut situation, I have found the following:


1/2" Spiral (upcut) bit...sharp... 1/2" depth per cut.
What's likely burning now is the waste from the cut that can't get out
of the way.
A single flute 1/2" straight bit will throw chips out rather well unless
the wood is gummy..like pine and such. Those bits really start vibrating
after a few sharpenings. Hard on the main bearing.
