Greetings all, I just used a router sled to "flatten" my old maple bowling alley workbench top and the next is do I finish or not? Also, the bowling alley had grooves between some of the glue lines of the laminated boards. Should I fill these in before putting a finish on? I was thinking of taking some of the maple sawdust and mixing with glue and making my own paste to put in the grooves and then sand it all flat. Any thoughts on whether to finish or not? Or my wood filler idea? Thanks in advance!
