SpudFiles

Edit: For the thread/buildup with these items..clicky...



Well today we were cleaning up around the house, and while we were at the tip dropping stuff off I had a look around and here's what I found:

A large coffee machine, a few parts were broken but it had a large, easy to read guage and a massive heavy duty stainless steel tank. I smashed up a few microwaves and ripped out HV cables, crimp connectors, the circuits etc.. And an old antenna (stainless steel) for pengun production.

The guage is a bit limited in pressure, so I probably wont use it on a pneumatic, but more likely for fuel metering or hybrid metering. The range isn't very huge and judging by the application, it would be extremely accurate.

The large tank will probably be used as the stand(and also fat tank/pressure tank or even a water tank for my up and coming w rocket launcher to overcome the flow of limited air lines. Either that or a portable gas cylinder for a cannon (far too heavy for a chamber, unless you mount it!)

There were a lot of fridges, and I would have got myself a compressor if I had the tools...Next time..

And some pictures....






Apologies for the flash..

That said, don't ignore the tip. But do remember, the things are there for a reason. Anyone else had a good haul like this before?

3" and 2" sprinkler valves for 3$ ish (cant mem) 3" was free aswell as tonnes of stuff non spud related

And another lucky <...> found awesome stuff in the dumpster!

The only thing I ever found was a fridge dumped in the bushes. Freon lines were already open. In less then 15 minutes I brought some tools and took it home
Some people have found amazing stuff for free. That coffee tank looks awesome.

usually high pressure stuff or any other stuff interesting for spudders (like big bore fittings) is expensive and/or difficult to get so it's logical that junkyards are great places for spudders

if you can get the compressors and if they work I suggest taking all of them...

Does that tank have a pressure rating on it? Looks like it could have potential as a fridge compressor reservoir.

In picture two it looks like theirs some numbers on the tank. If there's not you could call up the manufacturer and ask them.

Nice haul, did they just give that to you or did you have to pay for it?

The tip manager is a friend of ours, so we got it all for free.. The tank is pressure rated far beyond what you would need for this application (the walls are nearing 1cm thick, stainless). Asides from the markings, it's for holding the water as it boils, which generates pressure so it would have to be rated quite highly anyway. Wouldn't want employees covered in boiling water..





On an unrelated subject, the local mechanic (retired) finally got me a large whippersnipper (or weed wacker..) for my 1/10 scale rc project...It will be a monster.

1 cm thick walls????

That would easily hold whatever a fridge compressor can put out!

How heavy is that thing?

according to the DOT specs, steel scuba tanks rated at 3000(!) psi must have a minimum wall thickness of .164 (0.42 cm)at manufacture, but tend to run thicker, say, .180(0.46 cm) or so.

so i wouldn't worry about a fridge compressor


these are both aluminium tanks, wich range from 0.465 – 0.608 (1.18 – 1.55 mm), with a few oddballs having thinner walls.

You can't ignore overall diameter in talking about pressure capabilities.

It might have thicker walls than a Scuba tank, but it also has a larger diameter. However, I wouldn't be fussed by the 500-600 psi from a fridge compressor.

i know that
but i figured in this case it wouldn't make a difference of 2500 psi

and BTW most scuba tanks have a bursting pressure 2.5 times higher then the operating pressure

How did you measure that? I would look for a pressure rating if I were you.

It could be done the same way I calculated the average thickness of the walls of the copper pipe I use...

I weighed it, divided by density, then worked from there based on the outer dimensions of the tube.

You could also determine difference between the volume the whole tank takes up and the inside volume.
