Wall thickness .
« on: March 27, 2008, 01:11:48 am »
 What difference would it make if you used a .065wall inner tube with a .049wall outer ?

Also what is the optimum wall thickness?

From what I've read, the thickness of the inner tube isn't important. It's been referred to as a tube and a rod. The only thing with the outer tube is going to be your gap. The ideal gap mentioned was 1mm. Depending on the outer diameter of your inner tube, using a thinner outer tube would increase the gap.

Then again I'm new and could be wrong, or just partially right. Maybe someone else has a better explaination.

I used 0.065" on both inner and outer on this cell

and it has not been run yet.

I have some 1/8" solid rod and 1/2" thinwall tubing I want to put together; I will eventually.

Things go slow around here.

.065" seems a bit bulky. I decided to use .049...its cheaper and increases the gap with a thinner outer tube.

my  $.02 on the matter is that anything thinner than .049" is brittle and dents easy.
Best to use .049" IMHO

Some people use a solid innertube.
It should be related to some kind of Mass thing.
For me that part is stil undiscoverd.
Some persons are using an innertube and outertube with exact the same Mass.....
Meaning a thicker inner and a thinnen outertube, so the should resonate on the same frequency

I have seen that too thin is not practicle....

I have tried a slightly thinner outside tube as you said and had normal gas production ....

A thin wall should electrically spoken be a better thing to do, but mechanical it can be tricky..
