So I started down the slope of pen turning. I’ve done about 15 so far. I have been using the CA glue and BLO finish with some good success as of late. The problem I am having is that on darker woods especially, I get shiny spots that appear to be under the finish. I sand 220 320 400 1000 then apply BLO. 1000 again then wipe with acetone. When the acetone has evaped, I micro mesh from 1500 to 12000. Then I apply the finish. I apply 4-6 coats at about 900 rpm. Using thick CA I put a puddle on a paper towel and apply then put one drop of BLO on the same spot and work it back and forth till I feel the CA is cured. I then sand 1000 again and wipe with Denatured Alcohol. I then apply 2-4 coats starting at 900 rpm when the glue goes on (using a smaller amount) and when I go to BLO I up the speed to about 2300 rpm. I then micro mesh from 1500 to 12000 again. I take the mandrel off the lathe and go to the stiff flanel buffing wheel with rouge. Then to the soft flanel buffing wheel with white diamond rouge. I get a nice deep luster and high shine that seems to last well with handleing, but sometimes I get the shiney spots. It almost looks as if there is BLO trapped between layers, but I don’t know how. I would post some pics but I don’t know if a camera could even pic up what I am talking about. Has anyone else ran into this problem.
