still
can't seem to remove all the swirl marks. I haven't used walnut before so
I may
have to drop back and try the sanding process again from 120 grit or
lower. Is
walnut that hard that it may require a lower sanding grit to start from. I
have
paper from 80 for my sander. I'm using a festool 150/3 sander. I was
going to use Pore-O-Pac paste wood grain filler first then use a tung
oil.
Is there another way I should consider for a natural grain glass smooth
finish.
I haven't used a wood grain filler before so this is all new.
Thanks again.


Get the Bob Flexner book -- say from Lee Valley -- and have a look at
his sanding chapter...

Keep varsol or mineral spirits handy to clean the wood and look at a low
angle for scratches.

Sounds like you are not sanding for enough time at each grade. Spend
most of your effort at 120 grade and then move up only after the finish
is flat and consistent in appearance. imo

I usually use the ROS sander for the initial sanding and finish with a
regular sander and 180 or 220 grit paper . In my case with a Rockwell 1/2
sheet sander .
