SawStop #2 exhibited odd behavior. It would turn off (not explosively) about 10 seconds into my cut of a treated 2x6. I looked for a steward to get the bypass key in case it was related to the wood moisture. I cut the 2x6 into short pieces (my eventual need was 5.5x1.75 pieces) so I cut the 2x6 into 5.5" pieces. Then returned to the saw stop and they cut fine for the first 20 cuts then the SawStop fired. I red-tagged the saw, then went to WoodCraft and got a new cartridge and blade. They did not have an exact match on the blade. I got a Freud 50-tooth combination blade with a 1/8" kerf. I installed them and removed the red tag.
I’m curious about the initial behavior when trying to rip it down to 1.75" sticks …
Don’t think there is anything that needs to be done. Figured I should let you know.
the sensor for the brake mechanism would never just turn off the saw. if it senses while the blade is turning, it fires the brake if in normal mode. if not turning or in bypass mode, it flashes the red led on the box without firing the brake
the red paddle switch may be going out and intermittent on registering the “run” paddle being pulled out.
it’s not the first time. the controller box may look really though and industrial, but inside it’s just a lever that pushes on a pcb mounted micro switch, albeit pretty large for a microswitch
FYI: Clay I hate that you went off to woodcraft and spent so much money, but i am glad you did not get hurt. Just a quick question, did you take woodshop safety and if so with who? Reason i am asking is cause in that class they always go over do’s and don’ts for SawStop and by chance you do trip it you can go to Asmbly store to purchase both blade and cartridge for $160 as well as touch on how to override with the shop facility coordinator. Talk to Robert or Jason about those concerns.
@clayD pressure treated lumber is NOT allowed to be cut, drilled, planed, jointed, routed, or manipulated with any power tool. This too is explicitly covered in the wood shop safety class.
Actually, Michael, what I’ve been teaching in Woodshop Safety nowadays is that treated wood is not explicitly forbidden but very strongly discouraged at Asmbly. If the policy was updated to explicitly ban treated wood, that information was never passed along to me as an instructor.
I’m pretty strong in my discouragement though. The dust treated lumber generates is particularly nasty due to the chemicals infused in it during the treatment (though apparently it no longer contains arsenic). And I always bring that point up when discussing the saw stops, because I warn them that the moisture that treated lumber retains always puts it at the threshold of triggering the saw stop. I can’t explain the saw’s initial behavior, but it would probably explain the trip later.
Clay is a long time, very experienced member who probably took woodshop safety with Charlie many years ago. This illustrates the challenges we have getting updated policy and information out to long time members.
It has been a long time ago I took the class. First class I took so check my membership and that’s a good idea when I took it. Long before it was asembly.
I knew going in that it was a risk, though in my opinion experience a small risk. Not my first rodeo. I tried to get the bypass key but no one was available to get it for me.
It’s all resolved now.
I posted in the woodshop thread asking about the policies. If you’d like to discuss that further let’s do it in that more widely read forum.
