    Default Welding Tank Cart

    Part One

    The welding table and jig for all my work and the bender I made for bending the tubes I can only bend .875, 1.0 and 1.125 tubing so far.

    Part Two

    I made a welding tank cart for the heavy 4500psi tanks to move around the shop I take the gas and transfer it to the small tanks that are easier to move around.

    Good looking cart! I envy your shop space- looks like you've got a lot of room to move around. I'll have to check out youtube for DIY bender plans.

    Your making really good use of that bender. That tank cart looks great. Almost too good to be hidden behind a tank. What kind of press are you using for that bender?

    That's a great bender. I'm more interested in seeing it in more detail. Looking for a design that doesn't use a die. I guess that'll be hard to find as it works so well with a die. Maybe a DIY die out of schedule 80 or something along those lines.

    I bought a used die set on eBay and made my own dies after you buy them from http://www.mittlerbros.com/index.php...e-benders.html mine works the same but stands up right. I have drawing for the dies I made but I have a CNC mill to make them I think it would be cheaper to buy from Mittler Bros
    The pump is an air over hydraulic eBay $100.00 CA puts out 10,000 psi oil pressure slow but is better then electric pump it is to fast.

    I almost built a bottle cart just like yours (until I came across the storage shelf system that I used for my welding cart).

    I requested some plans online to build a very similar bender to the one you have, but I'm not sure that I want to go through all the work to build it when my neighbor offered to let me use his bender. I think that upright design is a much better arrangement (for saving space) though. It looks like your bender allows you to produce some very nice projects! It's even better than you can produce your own dies. What type of steel did you use to make your homemade dies?

    We have built a lot of tools. But a bender has not been one. The dies always seem to put us off. Yours looks nice, vertical design is great too.

    On the tanks, we have them on the backs of the carts or roll them until they need a refill, then we get a standard dolly, cap them and put them in the truck. They are not light, that is for sure.

    The dies are made of 6061-T651 Aluminum not steel they are not for production work but I have bent 1 inch solid stainless steel once 90 deg. with know problems you will be able to bend a few thousand bends with out damaging the aluminum. The one that http://www.mittlerbros.com/index.php...e-benders.html sell are aluminum.

    I transfer the gas through a booster pump on eBay $500.00 lines and fitting $125.00. Transferring from the 4500psig to the 2400psig tank I leave the system connected to the 4500psig tank to see the pressure going into the smaller tank till it is full. When the transferring from the 4500psig tank get down below 2000psig I use the pump to bring it up in the smaller tank to 2400psig the pump will boost the gas to very high pressure if you leave it running. So that is why I have the out pressure gauge to the smaller tank on the pump and the in pressure gauge to see how much gas is left in the big 4500psig tank I don’t pump it below 50psig it not worth the time unless the tank is empty then I will pump it out it will equalize to about 25psig and pump for a few minutes to empty then use a new tank of 4500psig.
    The transfer lines are 5000psig lines for air only not hydraulic lines they don’t have breathing holes in them and they will bubble the fitting are CGA580 (Argon Helium or mixed gases 3000psig) CGA680 (Argon Helium or mixed gases over 3000psig). The quick connectors are for high pressure water (pressure washers).

    More on

    Gage vs. Absolute vs. Sealed Pressure
    The conventional units for defining pressure are PSI, pounds per square inch. However, in all pressure measuring devices, a reference pressure has to be established and the PSI qualified to indicate the reference datum. The suffixes “G”, “A” and “S” identify the measured pressure as follows:

    PSIG -- Gage Pressure

    PSIA --Absolute Pressure

    PSIS -- Sealed Pressure

    By design, pressure transducers are available to measure gage, absolute or sealed pressure. The most common reference is atmospheric pressure and the units are designated at PSIG. In this case the measuring device is referred to as a Gage Pressure Transducer.

    Gage Pressure Transducer – PSIG
    Measures pressure referenced to local atmospheric pressure and is vented to the atmosphere. When the pressure port is exposed to the atmosphere, the transducer will indicate 0 PSIG. This occurs because the pressure on both sides of the diaphragm is the same and there is no net output.
    Venting is accomplished by means of a small diameter hole located near the transducer’s electrical termination – connector or cable. The vent hole contains a porous, stainless steel disk designed to filter out harmful airborne particles from entering the transducer.
    Depending on accuracy class, PSIG transducers above certain pressure levels may in fact be sealed. This can be done because the possible measurement errors due to sealing will stay within the accuracy specification of the transducer.

    Absolute Pressure Transducer – PSIA
    Measures pressure referenced to an absolute vacuum, hermetically sealed at 0 PSIA. When the pressure port is exposed to the atmosphere, the transducer will indicate atmospheric pressure; approximately 14.7 PSIA. This occurs because there is a vacuum on one side of the diaphragm and atmospheric pressure on the other. The net output represents the difference, which is atmospheric pressure.
    Depending on accuracy class, PSIA transducers above certain pressure levels may not have an absolute vacuum reference. They can be sealed with atmospheric pressure because the possible measurement errors will stay within the accuracy specification of the transducer.

    Sealed Pressure Transducer – PSIS
    Measures pressure referenced to the prevailing atmospheric pressure hermetically sealed within the transducer. When the pressure port is exposed to the atmosphere, the transducer will indicate approximately 0 PSIS. This occurs because there is a fixed atmospheric pressure on one side of the diaphragm and the ambient atmospheric pressure on the other side. If they are the same the net output is 0 PSIS. If they are not the same, then the net output will be a reading other than 0 PSIS.
    Depending on accuracy class, and design considerations, PSIS transducers below certain pressure levels are not available. Internal pressure changes due to temperature will produce measurement errors that will exceed the accuracy specification of the transducer. If a sealed transducer is required at low pressure levels, then the PSIA version should be used.

    Wow, that's good to know! I never would have thought that, but obviously it works well enough for them to sell those dies like crazy! I would have no problem machining my own dies from aluminum, even with my little lathe. Maybe there's hope after all!

    This the die I made and the dim. If you need more PM me or reply.

    Thanks for the dimension detail on your die. I saved it so I have something to go off of if I decide later that I want to build the bender. I'm still thinking of making the dies from steel for bending larger diameters of tubing (like 1.5").

    Buy the dies and then get the bender!!!! I have a set of dies for my got trikes bender. Now I'm just like go ahead and get the pro-tools bender. Got Trikes is a nice bender but it's bear to move around.
