Don't have the hang of getting a smooth cut on the inside walls with a
gouge so I use various round scrapers. This gives me some rough areas
where there is end grain. Can't seem to simply sand it out. Do I just
need more practice or is there something I've missed.
Mainly using claro walnut burl, maple and even some pine test pieces -
same result - rough spots on the inner and sometimes outer walls where
there is end grain. I buy the waxed blanks from various places and the
wood is usually from damp to wet, if that makes any difference.
Best bet is to learn to use a gouge more effectively. I know, not much
help, sorry. Scrapers tend to tear out so getting a clean cut is
harder. Try doing a shear scrape rather than a regular scrape, that may
help.
Use a freshly sharpened tool.
Run the lathe as fast as safely possible, and cut very very slowly.
When sanding, wipe the area with tear out with paste wax, then sand.
