After blowing out my first tall hollow form I had to give it a second try. I used my homemade hollowing tools and am very happy with them. I have found that I need to hone the edges occasionally to get better cuts. This HF is 7" tall and 4" in diameter. The hole is 1" diameter and the walls are fairly uniform at 3/16-1/4". I "sanded" the inside with broken tempered glass turning it on the lathe at about 50 rpm. Seemed to work pretty well. I've sanded the outside to 400, then applied a coat of shellac, sanded it back with 300 then wet sanded with BLO and 400 grit wet/dry. I have a flood coat of WOP on and think I will do a high gloss finish, although I'm open to suggestions. Comments and criticism appreciated.
