RO150 questions

[Zee]

Purchased the RO150 sander.  Job was to refinish
drawer faces, flat about 14x30. Started with
Cristal 60 rotary agressive. Took off poly finish
quickly.  Went with Rubin 80-100-120  and then
Brilliant 180.
Problem: I seem to get a few residual "curleys"
on each piece. Most seem to be from the 60
or 80 but a few are from the 120.  This is
prett depressing. Work piece was clamped
down tight, tried different speeds, less and
more pressure, tried handle 90 degrees to
sander direction.
Need suggestions to avoid this. Otherwise
the sander works quickly enough, dust free
too.

Zee I get that too. That is one reason i ordered a 150/3. I use my little PC 5 inch for the last grit or two after using the RO 150. But the speed of the RO150 made it worth it for me. they advertise you will only need the RO, I just do not agree with that. Especially on a project like yours.

I went at it REAL careful after finding the little circles after wiping on
a test coat of stain.  It is GREAT for the initial attack, but unless
I can tune up my technique Im reduced to touching up with
a block by hand.
Oddly, the higher grits don't seem to do it.

I'm a real newbie, but there was recently a similar discussion -- do you meticulously wipe down the surface between each grit? If you're getting a few swirlies, it sounds like a few particles might have come off the coarser sheet, remaining on the face of your material.

I don't usually, unless I am making a final pass before finishing.
