I'm having a brain cramp, which forces me to post a dumb question. I'm
building a wine storage cabinet (it's from the September issue of
"Wood"), and most of it is plywood. It tells me to "sand to 220 grit."
Great, I can do that...but, what grit do I start with?
If this wasn't plywood I wouldn't worry, but my fear is if I start too
low, then sand and sand and sand and sand, then I may go through the
veneer...or am I worried about nothing?
If it has dings and dents in it, like every pice of wood I handle,
you can wet those spots and wiat until they are dry before
sanding. That will expand them out. Otherwise you may
not be able to remove them without sanding through the
I even dampen scratches on the assumption that there are
probably some compressed fibers underneath the torn ones.
Thats an open ended question.
How thick is the vaneer and how much would do you think you need to remove?
Are there scratches? Start with an 80, 150, 220. Heck you can do it all with
220 if you have a few weeks to spare.
It's standard plywood, so whatever the veneer is on it. There aren't
any scratches to speak of...the more that I think about this, I
probably need to just wet it down and run over it with 80 (or maybe
even 150) to knock down the grain, then finish with 220. Only 2
sandings...I like that idea. ;-D

What sort of plywood? if this is furniture grade stuff, it's already sanded
at the factory to 120 or 150 grit. I'd actually either not sand it at all,
or start at 180 or 220, depending on the finish you plan to use.

Nope. Face veneer on plywood is at best 1/42nd of an inch, and some is now
1/100 of an inch. That's about as thick as a sheet of xerox paper.

It is absolutely a valid worry. For most of the furniture grade
plywood I have used, starting & finishing with 220 has been adequate.
The face layer of veneer on most ply is eally thin, I wouldn't want to
even get near it with anything coarser than 180.
If you're not sure it's best to sand a scrap and test with the finish
you plan to use.
No dumb questions, just dumb answers.

Given that my project are small yep, as a matter of fact I have a load
of walnut scraps about the right size for pen blanks. Problem is
investing in a pen making setup might be injurious to my health.
