I've tryed huge magnifiers only to get eye strain.then i found 650 power glasses on e-bay for $16.00.I'm very happy with them .I wear 250 power glasses for everything else.
I just tore into my 10th dw788 and found the wrist pin on the connecting rod off the motor had no grease.I replaced it with one i took a motor from and i'm good to go now.
