I am not new at scrolling just using modern saws. Last year I got a new saw My 20 Year Craftman was past its use fullness . I looked on the internet for a saw and The Porter Cable was the best saw for under $200, so I bought it, after about 6 month it began giving me problems, the Light and the air blower quit, So I hooked up an old fishing aerator and it worked fine, Well till about 2 month ago and it simply fell apart, I don't know if Porter Cable could fix it but I didn't want any thing to do with that piece of Junk. I Then bought a DE Walt 788. Which is working out fine , A bet My only problem with it .is At Age 74 I don't have enough strength in my fingers to tighten the Blades. I now use a wrench to tighten the Bottom The T one I can get without any problems.Is there any body out there that can give a old man any ?
