In a previous thread on saw sharpening the discussion turned to using circular blades and some comments about not sharpening them as it wasn't cost effective. And this leads to my question.
I'm a hobbyist WW with a contractor saw. Awhile back I bought a 40 tooth Oldham blade for it. It worked well for me so I got another for $40 as a backup assuming I would be sending the original out for sharpening. Well I put the new one on the saw and the first cut trimmed off my wooden miter fence. Runout one the new blade was
0.020 inches (about ten times what the old one is).. So that one went back. I then got a WWII. On my saw runout is virtually the same with the WWII and the old Oldham. To recondition the Olham (one new tooth, postage, etc) at Forrest will cost $40. At this point I have only made a few cuts with the WWII. The Oldham is twice as loud but I was happy the smoothness of cuts. Is it worth sending the Oldham out? On one hand why would I spend $40 to recondition a $40 blade? On the other hand can I get a blade as flat as my WWII for $40?So is there value of a flat blade?
TIA, Bob
