teflon jacks

[Eli Zilke]

Last year in corning I watched the Elio Quarisa demo and he used a pair of teflon jacks does anyone know where to get/ how to make them? I know there are health risks that go along with them but they cant be to bad he is in his eightys.

Today's price from my supplier here is $4.80/ft. for the 3/4", and $8.44/ft. for the 1". This is "Virgin" grade, machinable. The last time it had labels on indicating from Italy.
The 3/4" needed to be drilled out to run 1/4" s.s. rods for stiffening. I am getting ready to make another pair, as the teflon has grown flat spots with use after a number of years. Use real good ventilation.
Check your local plastics people, E-bay not always the answer.

You can get them from Roberto Doná and he makes two styles, round and jack blade. They both have a steel rod in them and are very nice.

What Jordan said...

Cancer, organ damage.

[Larry Cazes]

At least educate yourself on the health hazards before going this route. Do an internet search and get an MSDS from the supplier who is selling the material.

steel rod! Jeeeezzzz I made a couple different sizes after seeing them used at gas in Seattle. I shelved them because they deform when hot and just don't push the glass like wood. I guess I missed the part about the insert LOL.

I agree Teflon does off gas and probably isn't worth the risk. I still want to finish mine for that occasional use. Use caution.

Why Teflon? What properties could a plastic possess that would make it more desirable than a wood or graphite? I don't get it?

[Pete VanderLaan]

you know, I have a recipe for Calcedonia that users Mercury sulphide, which I actually have. I Will try lots of things, but I won't do that and I have superb ventilation. Think really hard about why you Have to have Teflon.

zero tool marks. Heats up very fast. Doesnt chill the glass like wet wood or steel.

i saw him at chicago hot glass..wrapped a spare set of jacks with teflon tape for plumbing worked great ....

[Rich Samuel]

Or, simply wrap each wood dowel with a few layers of wet newspaper. I once tried using those tubes from drycleaners' wire hangers shoved onto round-bladed jacks. Came this close to working.

[Rahman Anderson]

Cool trick but WHAT are you making? Is it that important? Maybe? maybe not.

[Rahman Anderson]

I mean teflon. coat hanger tubes ?

[Rich Samuel]

Hanger tubes. Can't think of anything else to call them.

[Victor Chiarizia]

i thought teflon gave off phozgeen gas (sp) like they used in WW1 in the trenches........hey, sometimes it feels like we are in the trenches! go for it! less glassblowers ? cool skin blisters and choking! i may be on to something. lets explore the use of mercury a bit more. vic

[Pete VanderLaan]

I have a genuine interest in the heavy metals. When I make the cad sel red, the outgas from the melt is bad enough but if I go ahead and clean the pot, there is inevitably liquid Selenium, or cadmium ( I think SE) in the pot bottom which really smokes. It changes the color of the water in the clean out bucket. Lead will do that to a degree and silver really does it.

I just find it hard to believe that the risks of Teflon make it worth the breathing of the fumes. It's not like my hood which pulls all the crap outside . It's right in the room, right at your bench. Right where you are leaning over admiring your work. People set up booths for powders and then do stuff like this. Why?

Wet anything will chill the glass twice as fast as teflon. I used to have a pair of teflon jacks, but disposed of them once i learned about how bad for you they were.

[Lawrence Ruskin]

What about Mercury whetted jacks?

Remember when you were a kid you could coat mercury on a penny and try and pass it off as a dime?

Might work.

Wait a minute someone sold parchoffis with the cardboard tube design (didn't they?) I have a pair second hand that came with a box of heavy duty cardboard tubes. Are you telling me crloo doesn't have cardboard tubes for my choffs? They have two large screws on the handles to screw into the tubes. I guess they could be custom but they work so well I thought they must be made by someone for the market. I barely wet them before use and they really work great!

[Pete VanderLaan]

You are right Sky.

[Victor Chiarizia]

the fireworks suppliers for amatures have tubes for rockets. try skylighter.com i think. cool site...but not as free since 9/11. vic

[David Patchen]

Who's gonna man up and screw some roman candles into their parchofi handles?
