The wood slicer blade is awesome as long as you are only wanting to slice, it has little or no set and is very thin so any free hand sawing can shorten it's life. The other blades mentioned are good all around general purpose blades.
Blade drift is found by taking a piece of ply wood at least 16" long and 6-8" wide -SQUARED UP!, draw a line down the center of the length, and mark the 8" point or center. cut fre hand on this line up to the 8" mark, and HOLD FIRM the ply wood as you turn off the saw and let it STOP. now measure from the edge of the ply wood to the miter slot or the edge of the table at the front AND rear of the table. this measurement will let you know what the off-set will be,I also mark the edge of the ply wood so I do not lose my reference points Then you can use any straight and square board as a fence to rip any thickness. as stated above, just keep it parallel to the reference line.
To keep rust at bay you can use steel wool and a liquid rubbing compound to clean the surface.then spray with a product called Dri-Coat
also from Highland. This will keep you top rust free and slick as a whistle.
it is all easy when you do it once or twice.
good luck, Chuck
