Why did my router bit smoke?

I am building a cabinet and screwed up. I forgot to rout the recess for the
backpanel before assembling it. I normally do that with a straight bit on a
router table; but I guess I was too eager to see it assembled.

Okay, no big deal; I used the rabbet bit off my rail and stile cutter. It
happens to be exactly the right size. If it wasn't for having to chisel out
the corners and around the shelves, it might even be a better solution than
a straight bit on a router table. Or so I thought.

I set it for 1/8" deep (3/8" wide) and did it. It smoked so badly I had to
take it outside. I did the other 1/8" in 3 passes, and even then it smoked
a little.

I don't understand why. I have cut many rabbets with it as part of the rail
and stile cutter without any smoking (sometimes in one pass); why now? The
only difference is that before the router was mounted in a table and now was
by hand, but I can't see why that would matter. I went real
slowwwlllllyyyyy, but it didn't help. (all red oak)

Okay, it is an old 1hp router, but it does the r&s just fine.

Any ideas would be appreciated, for future reference.

For sure you don't want to do the slowwwllllllyyyyyy thing. It is the
chips that carry away the heat so keep things moving. The bit is
still sharp?

Wade, check the direction of the cutter that routes the rabbet. I
went through the very same thing with one of the reversible rail/stile
bits. Created quite a bit of smoke routing some pine. After a bit of
time trying to figure out what the hell was going on, it wasn't until
I broke the bit down to clean it that I realized that I flipped the
rabbet cutter so it was trying to cut in the wrong direction. I was
surprised it cut at all and didn't explode on me. Seems I forgot what
the rotation of the bit should have been.

Is there any possibility at all that you mounted the cutter upside down?

Probably not. But clean it first before you use it again. Washing soda in warm
water does a great job of removing pitch build-up.

Rabbeting bits generally are meant to cut with their
sides, not their tops. You want a proper mortising
bit for cutting slots.

My guess is you went too slow. Even with the sharpest bit, there's
friction between the bit & the wood. If the bit stays on the same
part of the wood too long, then there's smoke.

Try again, and try to move the router along at about the same
speed as you would feed stock on the router table.

Mine still works. Cleaned off the gunk from using it backwards and put it
on the right way.

Always check your setup on a scrap piece of the same wood/thickness
etc before jumping right in on your good piece. You probably know
that, but in your eagerness you passed on this step. You were lucky
this time.

What's smoking? The wood or the bit? Is the bearing seized up?

Pathetically enough, yes, that is it.
If anyone else had done it, I would have said they were a moron. Maybe
there is lesson in there somewhere.

The cutter looks okay, presumably I haven't done any actual damage to it?

Thanks.
