also, if you read the instructions ( I know, real men don't read instructions), they warn you specifically to never extend the knife out past the point of the snap-line where the next blade begins. I mean if you look at it's design it's designed to break at multiple points, why would ever extend it out past the point where it's going to snapo ff and stab you

Recommend to not smoke during this!

I might suggest that regularly having many vats of gasoline and tubes in a location may be more dangerous than just cutting them out. I don't want to blow up or burn down myself or my warehouse. Also, sometimes you need it done now, not a week or two from now.
I use turpentine for Marquee and NEC tubes sometimes when I have time to spare, but it's really not that hard to cut a Barco tube out of a housing. I've done it 100 times without any injury. It takes about 4 minutes to cut a tube out of a G90 housing.

Ahhhhh you worry to much. If you only knew how many things you handle on a daily basis that could blow you up you probably would refuse to get out of bed in the morning. Now I'll really scare the $hit out of you. Do you pump your own gas??? What happens on a cold dry day when you slide out of the seat of your car and then touch something metal???
What if that metal was the cars body while you are taking the gas cap off and hear the pressure escape??? 
Something for you to think about next time you fuel up. I'll bet you'll never look at that cap the same way again

Isn't turpentine simply aged gasoline?

Nope. Turpentine is a distillate from tree sap. You're probably thinking of mineral spirits, which is like turpentine, but a petroleum distillate.
The whole vapor thing isn't a big deal. Just do it in a Home Depot or drywall bucket, and throw some Saran Wrap over the top with a rubber band. Do it in a ventilated space like a garage, and not next to an open flame (like furnace or hot water heater), and it's fine.
Like Chip said, most of us handle flammable vapor every day when we pump gas into our fuel tanks. The only major difference is you're usually pumping gas in open air. Where people get themselves in trouble with flammable vapor is in confined spaces with no ventilation. Flammable vapors are often heavier than air, so they "creep" on the floor. Bad combo when somebody is doing it in their basement 10 feet from water heater.

Yeah, but would you agree that soaking might be a preferable approach for someone who's never done it before, and can afford a few days (or a week, whatever it takes). And may never do it again, so isn't practicing to develop long term skills?

When I was still changing tubes I was a cutter. When I made up my mind that it was time to retube, it had to be done quick because I couldn't live without my projector. If you look back far enough it was me who originally suggested soaking in gasoline. I discovered how silicone reacts to gasoline when I was a auto mechanic long before some of you guys were born
Note: although not as effective as gasoline, patrolium based motor oil will eventually soften silicone.

Yeah, probably if you are a normal person doing this only a couple times than really using some sort of solvent (gas works) would be the only way I would suggest doing it.
I can't do it at my place because of the continued risk. Anyone could walk by with a cigaret, toss the but, it rolls near or under the door, and...

9" tubes stick way out and above of 5 gallon buckets... I tried that in the past. That's one of the reason if I use solvent I use turpentine. That way it all doesn't evaporate before the silicone is broken down.

I remember when you came up with the gas soaking idea. It has come in handy for me because there doesn't seem to e any way to take apart an NEC 8" tube without some solvent soaking.

Guys I soaked a marquee tube for 24 hours and it was still a pain to remove
I was wondering should I have soaked it longer or with the fill screw removed????
I need to know as I have two more tubes to do and want to get as much of that crap out before I go to remove the tubes from the cooling chambers
