Wait! There's a Bypass mode? Operator controllable? Uhoh! Suit City here we come, I reckon.

"Should I run my sawstop in bypass mode?" will replace "should I have a blade guard installed?" ?

In a working situation, is there any _record/log_ kept of each incident, and the state of the Saw Stop?

[J. Clarke]

Not really, bypass mode is specifically for metals and green wood that would trigger the Sawstop otherwise.

Old Nick,

I have no idea how diy came up with that address for me. I didn't type it anywhere when signing up. It's just designstrategies.net.

You've got a good hunch there. They had to include a bypass mode, and I wouldn't be surprised if the first person who gets bitten while using that mode sues SawStop claiming that they weren't running in bypass.

I have discussed the technology and the resulting saw's engineering at length with Steve Gass, as part of deciding whether or not to get one so early, but didn't get around to asking if the cartridge holds a record of operating patterns. It tells you if contact is sensed while in Bypass...would be trivial for it to record that info.

Most of the saw's smarts are in the cartridge. That make upgrades easier. If you happen to have endured reading my review you might have noticed that my saw received such an upgrade after I noticed an operational irregularity. At some point someone's got to try hacking the cartridge.

Regards,

Dave

It doesn't detect flesh per se, it's looking for a change in electric potential. Have you ever been in a building that has a door with a crash bar that youhave to touch with your bare hand in order to release a magnet that holds the door closed ?

[dwright]

Oh yea - Bypass Mode is a little irritating to engage. They did that to discourage its regular use. You have to hold a key turned for at least a second while starting the saw.

But does it work if you throw a sausage at it?

But it will be done...

Seriously, I am surprised they included it. Even after readin your other post.

Well it sounds as if somebody cares about your bum for you. Anti-spam addresses on the newsgroup are very common, to stop....well...spammers . Hence my little request to remove ns when replying by email.

I remain neutral about SawStop. Which to say against, really, as I have not bought one . But this one seems to be for _their_ protection.

[J. Clarke]

If they didn't then a lot of people would need two saws, one with Sawstop and one without.

[dwright]

Ha! It may not work. The switch is a momentary contact keyswitch and it would have been easy for SawStop to program the routine so that it must start open, be held closed for 1 to 2 seconds, and go back open or else the saw won't run. I don't know that they did that though. I might give it a try for the heck of it next time I'm out in the shop.

[J. Clarke]

But does the key also have to be released in order to engage it?

Oh I can see the need! I just feel it will _legally_ negate the whole thing somewhere down the track, unless they cover their arses very carefully.

Kind'a like buying a "chip" to gain 30HP on your car, I suppose.

[dwright]

J.,

The Bypass Mode routine is to hold the key turned while pulling out the on/off paddle. Hold that key position for at least a second while the motor spools up. Then release the key. It's worked every time I tried it. I haven't tried subtle timing variations to explore the engagement algorithm.

You do know that that is how performance mods are legitimately done these days, right?

[Edwin Pawlowski]

What? My water injector and the little fans in the carb venturii are outdated?

[Dave Hinz]

Well, water injection is also a legitimate technique - reduces combustion chamber temperature, and increases effective compression. A two-for-one effect in engines which can take advantage of it (turbo or super-charged, with engine management that can sense knock and adjust timing accordingly). Not sure about fans in the carb venturi, that sounds like a "magnets on the fuel line" kind of thing?

[George]

Sure augmented thrust on our old turbojets when the water kicked in.
