I can run 22" through mine with no problem. Like you said, it depends
on how much you take off.

Here's mine, FWIW, that I built about 18 months ago

Interesting way to do the paper, but you might want to check into
converting it to velcro backed. If you do this you can make sure the
drum is parallel to the table by putting the sand paper on a board, and
run it through sand paper UP, in effect sanding the drum as it turns.
It will be perfectly parallel to the table in the end.

My first thought was how did y ou measure to know it got 99% of the
dust?

Then checked your site. The pictures look good. But when it came
to reading the text, with the white letters, and that background, I
didn't even try.

If it can't kill you, it ain't a sport.

I measured the amount of time I spent cleaning up after, which was
zero. I figure nothing is perfect though. If I say 99.3 or something
then you can give me a hard time.

Yeah, black (almost) and white is a real strange combination... unless
your browser is doing something weird. There's a background at the
top that fades out, the only text over which should be the title.

You've got twice as much hp as I do, but yeah. For the type of stuff
I mainly do I've just got more width to not have to change the paper
as often, or run multiple grits at once. Though I tried putting 150
on it and still had to go over it with 100 on the ROS to get out all
the scratches, so I don't know if I'll bother doing that.

They all kind of look the same, don't they? :) You didn't have any
problems with the table rocking? Mine was pretty bad until I added
the locking knob on the side, but you doubled up your table. I see
that same design everywhere so I don't know if it's just me or what.

You made yours stationary which I highly recommend for two reasons.
First it's just a darn useful thing, mine's only been operational a
short while but when it's not on the bench I keep finding myself
wishing I could run one little board through for something. And
second that sucker is heavy. I was aiming for 50 lbs and really tried
to keep things as light as possible it ended up about 60 lbs. Which
is still in the realm of portable, but not real fun, especially with
it being an awkward size.

I saw the wedge clamping method on the Byrnes sander I link to on the
page. I figured being able to use regular paper was great. It's a
bit of a pain messing with the screws, but then I don't have to spiral
wrap the paper so I figure it's a wash. Bit of a learning curve to
it, had it come loose at one end once and scratch the hell out of the
lexan. Had a screw on the opposite side that was under the paper that
I failed to tighten all the way come loose and put a big line down a
board. But I think I have the hang of it now. I figured worst case
scenario I fill in the grooves and spiral wrap over it.

Yep, second to last picture shows this in progress.

How many hours did it take to make?

It went together over a period of two weeks, but I was building it as
parts were coming in and figuring things out as I went along. If you
don't get fancy with the frame there isn't really that much to it. I
was a bit nervous messing around with bearings as I really didn't know
anything about that, but don't let that deter you.
