I tried Woodcraft for sharpening and was disappointed. Then I tried a very competent shop (Daily Saw) in South Gate that covers two full city blocks sharpens blades for the meat cutting industry. They sharpen everything too for the commercial wood working industry there too. I took Forrest and Freud blades there. All their operations are computer controlled and take 12-20 hours. I spent $20-$30 per blade. New blades are $60. The difference is night and day to me. I need good blades not so so blades because I sell stuff. At $30/year to $60/year the new blades just work for my shop.Any reason you don't have them sharpened rather than buying new?
Yes but you have remember to flip every other board or one side will have gaps.Here's a tip Mark...
There's no need to get the blade to exactly 90 degrees, set up your boards and mark the top on each one, then rip one side face up and one side face down. In fact, if you want more gluing surface you can set the blade at 45 degrees if you want, as long as you rip one side up and one side down the two cuts will equal 90 degrees.
BTW, Freud is the only blade I buy, great performance for relatively little money.
