I learned a lesson yesterday.
A while back, I posted about putting a new blade on my 12" DeWalt 7790 RAS. The old one was a DeWalt which lasted me a long time, but was getting dull. I had previously bought a new Onsrud (German) blade off E-bay at a ridiculous ($23) price, lotsa teeth, -5 degree rake, etc., so I put that on the saw. Since it was thin kerf, I used my 6" Forest stiffener that I had used with the old blade.
It was a screamer, it made so much noise I had to use ear muffs. After a couple of weeks I took it off the saw, even though the cuts were great. I put a different blade on and went on with life.
Yesterday, I was doing some routine maintenance, and decided to try the Onsrud again. Before putting it on, I noticed that the stiffener plate had covered about a third of the squiggle slots, meant to silence the blade. Hmm...could it be? Yup, it could. After installing the screamer blade WITHOUT the Forest stiffener plate, it was quiet as can be.
Lesson learned.
