Hi Everyone,I decided to go down to the shop for a couple of hours this morning to continue work on the poplar bowl and begin completing one of the art show pieces. Off to work we go:Poplar bowlYoull remember from last time that the surface of the bowl needed more work. Looking at it after the first coat of varnish dried showed that the surface was scratched from sanding and the end grain areas had a lot of pitting and crushed grain fibers. This needed to be corrected before proceeding with the rest of the varnish application so I took it down to the shop and put it back on the lathe.I began sanding the inside with 120 grit sandpaper and 900 rpm. While the bowl is spinning I drag the sandpaper across the surface of the walls of the bowl very slowly and from the inside of the bowl to the edge of the bowl wall. I dont press hard on the sandpaper either, instead I just let the weight of my hand press down on the paper. The point here is to very gently shave the surface of the wood to remove any crushed grain and reduce the pitting on the surface. I went from 120 - 600 grit paper and this produced a smooth, shiny surface that was ready for another application of varnish:Here is the bowl after its been sanded:
And here is the bowl after a coat of varnish. Its hard to see but the surface looks much better:
