teflon jacks

[Rahman Anderson]

I will do the roman candle parchoff's. How 'bout every one just touches it less? I a'int perfect but I think that is the goal. I don't care what your tool is made of the less you have to do the better. Touch less. 15 years in and still all about goals! Right heat, right touch. It is glass.

I have jacks that I bought second hand that are coated in Teflon. They were made by Robert Toensing. By the time I got them the coating was worn off the blades but it is still on the handle. I have occasionally used the heel of the jacks to shape color and other hot applications and now I am thinking that is a very bad idea. Anyone know of a way to remove that Teflon coating without burning it off, which also sounds like a bad idea. I suppose I could go at them with some steel wool and see if that does the trick.

The best tradeoff is graphite parchoffis.

Back in the eighties some of my stock car racing compadres heard about using mercury in the chassis tubes to shift the weight around to where it would do the most good in cornering.

Further research discovered that a few drops of mercury spilled on a hot manifold in a wreck could easily kill a grandstand full of people.

How about that for performance art?

[Ben Solwitz]

Why would that help you corner? The tires on the inside of the turn are the ones that have less weight on them for traction, and the mercury certainly isn't going to move to the inside, it's just going to add even more weight to the outside.

I heard that the mercury would be placed in the frame tubes that run parallel to the wheels. More weight in the front when braking to improve traction and more weight over the rear to improve traction during acceleration. But then again I used to roadrace motorcycles where there is a lot more braking for tight corners as opposed to oval track racing. We also knew how to turn right.

Racing bikes back around 1920 had no brakes at all. The attitude was "Why would you want to stop?"

[Ben Solwitz]

The mercury is going to shift the same way as the rest of the weight in the car. If you're braking around a turn you have to worry about the traction on your back tires, not the front. I may or may not have done a 180 on a turnpike exit ramp a few years ago...

[Drew Jaeger]

But on a bike most of your braking is done prior to turning, you should be on the gas through the turn. Never done 180 on a turnpike but wide open through turn 1 at Brainerd International Raceway at about 150.

Now that would be a rush! That's at the end of the long straight away isn't it? Trust the force Luke! Trust the bike... look where you want to go and relax! Yeah sure! I'd have a racing stripe in my shorts for sure! Way to go!

[Drew Jaeger]

Yep, mile long straight and wide open on most bikes. Raced up there for about 10 years but have not been on the track in just as long. Got too expensive so I took up dirt bikes. Half the rush at a fraction of the cost.

[Patrick Casanova]

I ride a Dual Sport today for the same reason. I can experience just as much fear at 25 on a logging road as I did on my BMW K bike in the twisties at three times the speed. And with out the speeding tickets.

How about parchoffi rods made of boro?

More than once I've wondered how a 3/4" thick slab of boro would work as a marver.

[Dan Ellis]

If it didn't break it would probably stick. Boro is still subject to thermal shock.

And expansion... it's a 33 as opposed to a 96.
