« Part 2: The Yellow Screw, Oh That Yellow Screw Part 3 of Sawstop Tips From the User's Perspective series no next part

So I was milling a shallow groove in a custom hardwood fence for a t-track. I already had a t-track installed on the opposite side of the fence. My Infinity dado blade hit the tip of a screw in the fence and fired the brake.

I was sending the workpiece through the saw with a push paddle, but I must have brushed the t-track with my trailing hand. In totally unceremonious fashion, the blade immediately dropped below the table and munched the dado brake.

Getting the blades and brake off was a chore. Surprisingly the blades don’t look damaged, but I probably won’t use it again just to be safe.

My big worry was that I’d bent my arbor on the saw. I tested it with a Snapcheck digital gauge, and to my surprise each tooth was within .001”. I think I got lucky, but I’ll switch to a recommended blade for sure.

Bottom line, the Sawstop did its job. Lesson learned!

Oh well:) Looking at the at end of my Kreg mitre gauge I guess that would of been at least 3 brakes? (If I had a S.S.)

Yep, a $300 mistake for me. Happened before I got anything done in the shop today.

To be fair, it was 100% my fault. The Sawstop worked perfectly. First brake activation since I bought my PCS 5 years ago.

Live and learn.

It’s a good thing to know, though I’d much rather you’d sacrificed a hotdog instead!

When you say “recommended blade,” do you mean a dado blade that doesn’t have the safety or anti kickback protrusions after each tooth? I don’t use my dado in my sawstop, but am thinking about setting up for it…but want to get the correct, and good quality dado blade. What are you looking at as a replacement?

Have a 3hp.PCS…purchased after I really needed it. Another story…not my most shining moment, but I can still count to ten without using my toes so all OK. I also had an activation. I’d been ripping some KDT treated with the safety bypassed. Even with the treated the conductivity warning light never came on, but was just being careful. Finished ripping and cleared the tabletop of debris. Next time I turned it on, I heard a thump, then nothing. Looking under the table insert, the paul had been activated and I noted a small shave of treated laying across the riving knife portion of the saw guard touching the blade. My assumption is that as soon as the blade moved, it caused the shave to shift into that position, because the saw shouldn’t have started if it sensed a continuity. Happened fast…the blade barely scored the paul. Was a bit gun shy for awhile, thinking it could have been a false activation, but have had no problems since.

Lesson learned! After cutting treated, I blow out around the blade!

As far as dado blades, you need a set without anti-kickback teeth, and one without full blade chippers (because of weight).

You’ll be looking at Ridge Carbide Dado Master, Dewalt 7670, and Forrest Dado King. None of the current Freud dado offerings meet Sawstop recommendations. Ideally, get a set with 24 teeth and 4 blade chippers.

Thanks for the tip on the treated wood. Sage advice.

Yes, I was on the sawstop facebook group the other day and learned of the antikickback features on some blades. I have set aside a couple of nice frued blades that I really like and reorded a blade without the feature. Should have known though. It’s in the manual. I hated to do it but I figure if it compromises the reason I purchased the saw for in the first place….

Well, I’d love to get a Forester of course but I opted for the same level as the frued I had and picked up an Amana combination. I might grab a dedictated rip blade at some point when I make something where a lot of ripping might be needed. I love the frued I’m hoping the Amana is okay.
