My local Woodcraft offers a blade sharpening service. They job it out; a guy comes by every Wednesday and brings back sharp blades the following Wednesday. I had no idea how bad my blades were. They came back with plastic coating across the newly sharpened toofs. I pitched it on the ole Shopsmith and ran a piece of mahogany from the scrap bin through. Seriously, it was like a hot knife through butter. I was amazed at the cut quality. The saw made a completely different sound. Looking back the saw was struggling to push the blunt blade through the lumber.I think it was the first time they had been sharpened. These are quality blades that I got with the machine. I think the previous owner would use a blade until it got kinda dull and bought another one. The oldest looking one, a Systi Matic is the one I put on the saw today. I put the other, an Amana, in storage for later use.
I would encourage anyone that has been struggling with cut quality, or a struggling saw; GET YOUR BLADE SHARPENED.
Cost? A bit over $20 for a 50 tooth blade. Some of the best money I’ve spent in a while.
