Tighting saw blades

[ike]

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 ?

the Ex21 and DW788 have the same handle.  I made the DW788 oblong one and have used it for two or three years - above and below table.

Watch out using a wrench to tighten the blades on the Dewalt.  The blade holders are just cast metal, and you can split them or at minimum bend them so the blade holding set screws do not sit flush on the blade anymore, and you will not be able to hold a blade.
