Topic tags/keywords: saw stop humor

I am working on a special project for a friend of mine. It requires that I cut deep slots through four pieces of maple.

Cutting the slots gave me an opportunity to finally use the Grizzly tenoning jig that I bought a while back. I couldn’t actually see the blade, but I sort of pushed the jig across the table saw and noticed that the clamp looked high enough to clear the blade. I wanted to make a few test cuts so I put a little piece of particle board in and gave it a whirl. Unfortunately, the blade was too high and it hit the clamp on the tenoning jig. So, not only was this the first time I actually used the tenoning jig, it is also the first time I activated the brake on my saw stop.

The blade and the brake fused together made it rather difficult to remove them. Anyway, I think I am done working in the shop for today. I’m going sit in the living room and pass out candy and deal with the saw tomorrow.

Without showing my ignorance, why such a deep cut? And did you try the cut on a single pass? My alarms would have been screaming at me.

My previous cut on the saw was through 3” thick maple. The actual slots that I need to cut are about 2-1/4” deep. The purpose of the test cut was to see the quality of the cut on a board that was clamped on to the tenoning jig so the blade was set kind of high. I would have no real concerns about a 2” cut on a board that was securely clamped to a cast iron tenoning jig, well except for the blade hitting the clamp!

Charlie,

I guess Murphy went to your shop after he took the cover off my concrete so they could become blocks from our recent downpours.

Trick not treat? :<)

Ouch!

Wow! That must have been a shock. Costly too, with a new blade, brake cartridge, and fresh underwear.

Thanks for posting about your incident. It prompted me to go down to the shop to check my gear. I have a Delta tenoning jig, and a 3 Hp SawStop. I can confirm for others that at full elevation the blade will contact the swivel end of the clamp just as you found for your Grizzly jig.

As was mentioned, I am not certain when I would ever have the blade that high with the jig, but it is good to have a reminder to check for non-obvious issues when setting up for a cut.

Would the blade and brake have fused if the clamp was wrapped in bacon?

From experience, unfortunately, I can tell you when the blade brake is activated – it’s very, very loud and fast. It’s enough to make you stop for the day. And yes, it’s expensive.

Maybe just me but I would have serious concerns with a single 2” cut, tenon jig or not. The jig itself should let you make repetitive cuts in small bites (allowing you to clear the saw dust that I find tends to eat blades) and the time factor would not be an issue for me. But I only use an older Delta contractor saw and it would “balk” at the thought…maybe that’s not a bad thing. But you still haven’t explained why you need that deep of a cut!

The cabinet saw does pretty well with deep cuts, but you are absolutely correct,, if I still had a contractor saw then I would have to make multiple cuts. I would love to let you know more about the project I am working on, but I can’t get into too many specifics just yet. I will tell you more about it soon.

I think the board moved a bit when I set in on the bench and that’s why in the first photo that I posted it looks like the cut stopped before the blade got to the clamp, but it certainly did hit the clamp.

I had to look very closely at the clamp to see where “I think” the blade contacted it. The spot is so small that I couldn’t get a photo with my phone. Even with my Canon SLR it was hard to get a picture of it, but if you look closely you can see two very small dents in the clamp:

Sorry about that…I have had it happen hitting my miter gauge.

With a Forrest blade, I would pull it out and send to Forrest and see if it can be saved. I did it with a Freud rip blade and not worth the cost to have checked.

I mounted my blade with cartridge on a plaque right near my saw as a reminder to my lack of attention.

Good Luck

Thanks Redoak,

I like the idea of mounting it on a plaque! But I will probably go with your first suggestion and send it in to Forrest.

You know, I have had the saw for about 10 years and this is the first time this has happened. I even cut aluminum with it once. I guess one brake and one blade repair in 10 years isn’t too bad.

All I can say is, WOW! At least you’ve got a photo to frame. I can only imagine how high and far you jumped when it slammed to a stop.

If I were not so lazy and didn’t have to respond to trick or treaters I would take a picture of my Forest WW II with the Sawstop brake attached to it ( which is mounted right over my sled to remind me to pay attention) An aluminum nail activated my brake. Good idea Redoak49, think I will talk to the Forest people and see if they have any experience. (Maybe I could talk them into developing expertise in this obviously growing field.)

Looking forward to seeing what you are up to! For awhile I intended to upgrade my meager collection of power tools (like an 8” jointer to replace my trusty Delta 6” and a cabinet saw to replace my trusty Delta contractor saw and a stationary planer to replace my equally trusty 13” Delta “lunchbox”). For some reason I seem to have tired of the hobby and decided to make do with what I have.
