Sawstop Bang

[Birdhunter]

I was cutting a dado in a jewelry box side using a tenon jig on my Sawstop. The blade was tilted to 45 degrees.

Almost all the way through the cut and BANG. The safety device had fired. The saw blade had barely touched he steel jig and triggered the cartridge.

I just had not seen the interference at the very back of the jig when setting up the cut. It was a very expensive mistake.

But, on a standard saw, the blade would have made full contact with the jig. I'm not sure how that would have ended. Probably, not well.

I mounted a new cartridge and a new saw blade and checked the alignment of the saw blade fearing the jolt would have knocked everything out of true. All was well.

It was an expensive lesson and one I will not repeat!

Was the original blade toast after the bang? I thought I read somewhere that sometimes the blade is still good.

Sorry to hear about your experience and after using my table saw for 35 years I never felt intimidated by the machine and accidents like yours is the reason I would never have a SawStop.

I did read in Fine Woodworking magazine recently that most times the blade can be saved but, they recommend that you have a knowledgable sharpener look at it and replace any cracked saw teeth.  I think If I can remember they asked the folks at Forrest if one of their blades could be repaired and the response was from the Forrest People.

Thanks, but the contact of the blade against the steel jig damaged the saw blade more than did the Sawstop cartridge.

I'm very thankful I did have the Sawstop. If the contact of the blade with the jig had progressed further, serious damage and mayhem could have occurred.

Welcome to the club....I have done almost the same thing you did and the last time I set off the brake I used my index finger, didn't break the skin.

It's a great saw to have I hate to say this but you have to experience the brake going off to really appreciate what it does

I've owned my Industrial Sawstop for over 2 years and this is the first "bang" I've experienced. Hope there isn't another.

I ordered a replacement cartridge yesterday about 11AM from Amazon. It arrived yesterday evening around 6PM. Free shipping to boot!

I'll order a back-up Forrest Woodworker II blade today.

I always keep a cartridge in stock. Mine was one of the first contractor models and needs  a legacy cartridge which I believe has fewer pins in the interface between it and the saw.  They are not compatible. 

 

[Birdhunter]

I had a back up cartridge and another saw blade so I wasn't out of business for long. I did want to fully check alignment before I fired up the saw again.

Don't forget to stock a spare set of underwear too

Mostly frustration with myself for missing the interference. Better frustration  than amputation.

Missing interference is common, I have a nice "reminder slot" in my sliding table fence ;-(  I also refuse to work with used wood with potential hidden nails (a lesson I learned a long time ago).

Some years back I was cutting a used 2x4 on my tablesaw with a fairly new 12" blade.  I hit some hardened masonry nails and chipped or lost several teeth on the blade.  I still use the blade and even with the slight damage, the cuts are smooth as silk.  When I finally send it in for resharpening, I plan on finding a shop capable of replacing the damages teeth.

I don't know how the SawStop "bang" affects the blade, but if the damage was mostly caused by the interference and is limited to only to a few teeth, maybe it can be easily fixed.  Are you planning on sending your blade in to see if it can be fixed/sharpened?

I also have a sawstop and hope I never have to experience the "bang". For those that don't know how sawstop works, the "bang" is a result from the aluminum block attached to the cartridge slamming into the saw blade while it's running at full speed. The blade is then embedded into the cartridge which is how the blade is stopped so quickly. I don't know about you guys but I'd rather just fork up the $120 for a new WWII blade then try and reuse the old one.

FWIW Mike, Forrest offers complete blade service including sharpening, straightening and tooth insert replacement. [big grin]

My saw blade embedded in the cartridge is going to hang on the wall by my table saw as a reminder to be more careful!

Excellent...that couldn't be a more perfect reminder. [thumbs up]

Thanks for the heads up on that.  It's not a Forrest blade, but I see that they sharpen other brand blades and they don't seem to be too expensive.

I agree that hanging it is a good idea.  Though, I have to say that after experiencing the "bang" at several of the SawStop demos at tool shows, I think that "bang" would be forever etched in my memory if it happened to me when I was sawing!

Thanks, Mike A.

I mounted a new cartridge and a new saw blade and checked the alignment of the saw blade fearing the jolt would have knocked everything out of true. All was well.

While researching my Sawstop purchase, I read where Sawstop has the beefiest arbor in the table saw industry.  The reason being so that it can withstand repeated brake firings.  I found it also makes for buttery smooth cuts.
Glad to hear the technology works, and that you were unharmed!
