Need to find/make a box capable of holding air pressure...
I need to obtain or fabricate an Al or steel box, it needs to be about 6"x6"x4" size(I can work with sizing), drillable sides(at least on tappable), and withstand at least 50psi internal pressure high, with a sustained around 32psi.
Is this even possible, better yet safe? Lol.
It would be trunk mounted.
Don't even try to speculate what its for, you'd be wrong.

Any reason it has to be square?
If you just need the volume, it may be safer and easier to stack a few tubes of 4inch SCH40 PVC pipe tied together. Rated at 100psi, it would be lighter and safer.

tubes could definitely work. I wasnt sure or the PSI rating. Do they come in a say 3" diameter, even though 4 would work. and i assume id just use end caps to seal them off? but would the ends hold the pressure too?
point of the square-ness is for neater packaging. Could always put the pipes in a plastic housing. hmmm

Yea if you get SCH40 or 80, they are rated at 100psi, and with the proper prep and glue, the end caps will hold no prob.
I used it all the time to make air cannons etc.. you can get 3 and 4 inch stuff all over, but if you go to lowes/home depot, make sure you do NOT get the DVW stuff, its thinner and will not hold pressure.

ok, ill def have to look into that. once my idea is complete, ill post up about it.
its something im trying to make to sell eventually, and im thinking cost wise. As of now im already looking at 100-150 for main components, then 10-20 for secondary components, and final cost would be the container. Im trying to stay under 225 total and this may work now...

Is this for a air ride suspension?
What kind of volume does it need to be able to flow at once?

TIG one out of aluminum, then put bungs on it for your pressure fittings. You can probably get a radiator place to do it, and if you get the fittings put in you can have them pressure test it. Or mod something like this:

You may already have one of those- you still have your Vette, right?
Based on these pressures, sounds like an oil application

Would a hand held propane torch tank work? they are about 4"x10" or the mini-grills use tanks about 6"x8". They are probably built stong eough for the pressure you want, if you need more you could probably cut the ends off and weld two together? Can you adapt the propane fitting for what you need?

main issue is i need to insert an object into this container prior to closing it up. cant really do that with a propane tank. cuz most welders aren't skilled enough to make something air tight.
the PVC pipe idea will def work. and it would be a one time fill type of thing, and only add air if need be once every few months, so no fitting connections are needed.

Why not get a 12V air compressor, or mount a compressed air tank?

If your planing to use the original sensors it may not work. The sensors work by centrifugal force. Under 20 MPH the sensors are in stationary mode and will only transmit once every 60 minutes, over 20 MPH they go into drive mode and transmit every 60 seconds. If the computer does not see the sensors go into drive mode your going to set the TPM light.

correct, stabilitrac will not shut off nor will competative mode engage

this is the issue im currently looking into
edit: do you have any specific info on this exact setup and what the ecu requires to see etc.?

You could do something with a magnet, that would hold them in drive mode.

doubt it, i think its in the BCM, hp only gets me into the ecm.
ill look into it.
i wonder if i could find out how to capture the RF id code, and try to clone it into a chip based electronic device that would be programmable... hmmm. time to talk to my tech buddies.

Not that I know of easily, because I tried to do that with my Exploder since my summer wheels/tires don't have sensors and I check my tire pressure once every 2 weeks anyway.

i was pondering... if i can open up the sensors and bypass the inertia circuit with a relay perhaps(from what i read they just "sleep" until movement), it would activate the sensors as soon as you turn on the ignition, and the self contained batteries would hold the info so it wouldn't have to be rest each time. Then car off, would allow them to sleep once again.
