OK, folks.....I need some more help. Have just finished my first few pens. They look pretty nice; but I am not satisfied with the finish. Most, but not all, of the blanks have very fine rotational scratches. You can't see them at normal "writing" distance; but they are noticeable in the right light at a couple of inches. Most people probably wouldn't ever notice them; but I do and want a better result. I'm new to woodworking and finishing so I don't know what the problem is(wood or finish) or how to go about solving it.
A few details......
Sanding: I start with 150 grit and go through 600 and then micromesh thru 12000. Sand with the lathe running and then turn it off and sand longitudinally for each grit and dust before going to the next grit. I don't see any scratches on the wood after final sanding; but maybe the finish is bringing them out??
Finish: Nothing fancy. The lathe came with HUT Crystal Coat and that is all I use. Put a drop or two on a paper towel and apply it to the wood with the lathe off. Then turn the lathe on and friction polish. Generally use about 5 coats.
One thing I do wonder about is the sanding grits that I am using. When I bought SP, they did not have 320 grit so my current sanding routine skips from 220 to 400. Is that too big a jump?? Should I look elsewhere for some 320 grit SP??
How do I figure out if the problem is the sanding or the finish??
Another question.....I have seen a couple of suggestions that friction polish doesn't hold up very well in situations where there is a lot of exposure to handling?? I'm making pens to be used and not put in a box for show. Is there a better way to finish them than a friction polish and not terribly lengthy or involved?? And finally, would I get a better result if I used a sealer of some sort??
I know this is sort of a load.......sorry. I've read both Dick Sing's book and the one by Christiansen and haven't been able to solve this for myself. Any help will be greatly appreciated!! Thanks.
