Don't know if anyone wrote about this and haven't seen any messages about this but this has helped me cut with a sharper blade. At the first sign of my blade getting dull, I secure a 1/4 piece of plywood on my table and thread the blade through the hole that I cut out and then do my work on the plywood. The 1/4 inch thickeness seems to help by making use of the part of the blade that never touched the project before. Don't know if anyone else has tried this but this has helped me.
This will work fine unless you are using reverse tooth blades, raising the table you would not be utilizing the reverse teeth. To bad they couldn't incorporate a table that raised like a drill press table. I usually cut with reverse tooth blades and just toss them when dull. Will have to try the crown toothed blades.
