I'm in the final steps of sanding a project and have noticed some sanding swirl
marks. I have been very careful to step up the sanding grades from
120-150-180-220. I have even tried handing sanding this test board. I 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.

The current issue of WOOD magazine has a really good write-up on finishing various woods. It should help.

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

Actually Black and or American Walnut is pretty soft compared to Oak. I
never go past 180 on Walnut or any other wood and usually start with 150.

As Leon said, I start with 160-180 and move up from there. However, I
prefer a scraper for finishing walnut.
Secondly, swirl marks seem to show up only if I allow the sander to stop or
start while in contact with the wood.

What type of sander are you using that caused the swirl marks?

swirl marks show up if you move the ROS too fast, also.

LOL... Probably the smartest response.. Especially if a Non -Random
orbital sander is being used.

It's a random orbital 6" sander festool 150/3

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 .

What brand of paper are you using? Not all are created equal with
respect to quality control of grit sizes. I now only use Mirka brand and
have had excellent results over the more inexpensive Porter-Cable-type
branded home/hardware store selections.
