    They're used kegs. As long as they hold pressure and I can sanitize them, they aren't garbage.

    once the handles start coming apart they will fall off soon. Once the last handle starts to disbond, you'll have a hell of a time moving around those kegs.

    Never thought of that. Thanks for the insight.

    I was just looking at those. $25 is still pretty cheap nowadays.

    i have one that is starting to come apart. im going to epoxy that thing back on before it tears

    yeah thats a great price. the pictured one is a little beat up, but not too bad. I have two of that style (bought locally) and they work nice. a little harder to manage, you can't set it upside down to drain and you can't stack them at all

    Epoxy or JB weld. Can never go wrong with JB weld. Unless you want to remove it someday.

    never want to remove the rubber handles. im thinking JBWeld would be to rigid. The kegs expand significantly when pressurized. you'd likely disbond pretty quick due to internal stresses from the difference in Young's modulus between the two materials and the stress risers from thickness changes. A flexible epoxy or polyurethane adhesive would likely work better. I'll let you know what I find.

    I generally find slammin deals on Craigslist. They come and go, but there usually is a doozie.

    I bet JB weld would work, simply because I doubt you are getting that much steel expansion due to the geometry of the keg. Flexes a lot in the middle, not so much on the convex ends based on the simple equations for cylindrical and spherical pressure vessels.

    Cylindrical : stress = (pressure)(radius)/(thickness of steel)
    Spherical : stress = (pressure)(radius)/(2 x thickness of steel)

    Of course, the ends of a keg are probably not exactly spherical, but my intuition makes me think that the steel will not flex nearly enough to break the weld. Especially when you consider that we are only loading the keg with 30-40psi max. I think the weight of a full keg when picked up will equal more stress on the epoxied/welded area than when pressurized. Of course, I am also wrong a lot.

    I'll measure the radial expansion as well as the longitudinal expansion from the bend to the top of the keg next time I have a chance. They are far from spherical.

    Cool. I wonder how you would determine the stress factor of an oval or oblong shape as compared to a cylindrical shape. (ie, instead of a .5:1 for sphere:cylinder, a X:1 for a oval:cylinder) This is all very interesting and academic of course.

    I would just model it and run an FEA. :)

    That's actually not a bad idea, but seems like something, someone should be paying me for. Besides, I don't have ANSYS on the home computer.

    I drilled a hole in my fridge and have the gas run in through the back. It allowed me to get a whole 'nother keg in there. the fridge can hold 6 5 gallon ball lock cornies!

    i installed a gas manifold inside the fridge, so it's only one line running in.
