This is probably a simple question, but I've been sanding a table top
for a couple of hours and I keep having to regress on sand paper (that
is, I keep finding scratches the current grit will not take and have
to return to a previous grit). I'm starting around 50 and going from
there. Can someone recommend a sequence that will help to alleviate
this roller coaster sanding job?
Thanks,
Jeb
I'm using both a belt sander and a finishing sander, I can't help but
wonder if a 100 grit on belt sander isn't coarser than a 100 grit on
the finishing sander. Is there any credibility to this thought?
50 seems pretty coarse to start off with on a 'finishing' job?
Any reason?
I usually start with 120 or even 160 depending on the wood and go from
there...

Belt sanders heat and harden the surface of the wood. Also, by their
design, they lay all uncut fibers down in the same direction. Use of a
cabinet scraper or plane is best, though scrapers don't work well on stringy
softer woods, followed by sanding with a Random Orbital Sander or an
orbital.
For now, I would recommend you break the surface hardening by wiping with a
damp rag. Allow to dry, then use your finishing sander.
See what I told you about pressing the uncut fibers down?

I don't know about the rest of you, but I usually try to start with
just inside the station, then move up to the lift/launch, and then
tackle the rest afterward. Only takes a few days on a smaller one, but
up to a week on the really big ones. Slap on a fresh coat of paint,
and the rails are usually good to go for another season.
Oh...wait a minute! This is the woodworking newsgroup, not
rec.roller-coaster! My bad :)

You will keep chasing your tail until hell freezes over.
Find a commercial sander in your area and have them run it thru their 48"
wide sander.
$20-$30 and it will be flat, smooth and ready for finishing.
