re: Workbench/ Outfeed continued

I have used tempered Masonite on splines that pass all the way down the length of boards many times. It’s as thick as a regular pass with a non thinned kerf table saw blade then allows just enough glue. My passes are 3/4" deep then I use a 1-1/2" wide piece of Masonite. The strength is amazing, more important is the top aligns perfectly. As Jeff has noted, it’s a good idea to stagger the joints. I have even used this way of board lamination on guitars, with great results. I did however use instrument glue so as not to affect the sound quality. Then when dry and shaping it still allowed me to tune the wood to the desired note.
