Just back from buying some 3/4" quarter-round (well, 95/128" or
whatever) . It isn't a quarter circle profile, though. The right
angle part (the middle of the circle) has been machined off. Didn't
check every species in the yard, but the pine, maple and faux-mahogany
were all like this. Checked a piece of 1/2" and it was a full 1/4
circle profile.

Not a big deal except at doorways. I usually just do a little angle
cut, but if you don't do a proper return with this stuff, you can see
a little notch at the end of the run.

Any idea why the corner gets trimmed off? Seems like an extra step in
the production process.

Thanks.
