I've got the pics on my computer now, and I'll send them to anyone
who'd like them. Maybe this weekend I'll get set up with a real
newsreader so I can post them to the binaries group. Now that I think
of it though, my last free feed didn't maintain any binaries groups.
(It was the (some) german server, I think.)
IAE, I did some experimenting with different woods today and wanted to
follow up. The biggest frustration I had with using a router was chip-
out at the very beginning of the cut. I was initially using reclaimed
douglas fir, which can be brutal for splintering. I was able to
eliminate the tear-out itself by climb-cutting, but the little chips
at the initial plunge were going to be a big issue, I could tell from
just a couple test cuts. I'm not sure if this problem could be
eliminated by using a new or newly sharpened chamfer bit or not. My
guess is that it would help, but not totally eliminate the issue. So
I built a sanding jig.
This jig solved the tear-out/chip out issue entirely. I had zero
instances of either. As for burning though, I did have some very
slight darkening at either the beginning or the end of the cut on a
few occasions. It was so slight though, that I didn't even bother to
try and remove it; it was just a slight browning of the darker
(harder) growth ring. And once I got the hang of getting the piece in
and moving smoothly, I didn't have any trouble at all. If you let the
wood sit in one spot, it *will* burn. I would lick my fingertips to
get a good grip on the wood, until I was devoid of saliva. Then I put
on some rubber gloves. Much better, the latter.
As you'll notice from the pictures, the chamfer I was making was quite
small - roughly 1/4" across the flat. And this in a relatively soft
wood. Today I ran some cherry, oak and maple and the results were
somewhat less heartening. I was able to make clean passes the
majority of the time, but there were enough instances of burning to
make me really not want to do it in one pass. What I ended up doing
was taking the bulk of it in the first pass, then bumping the jig
forward a smidgen and cleaning it up with a second run through.
Technique was vital, even on the second pass. Cleaning the belt with
crepe helped. An oscillating edge sander might help even more.
At the end of the day, using a sander for chamfers isn't a panacea,
but it's definitely a very nice trick to have in my quiver.

I don't ever check the jaypique addy anymore.
