  • O/A cart - something a bit different

    OK, here's my first project post. This Oxy-Acetylene cart is my 4th project with my MM180. I'm particularly pleased with the unique design and fairly decent execution.

    Made for 80 and 75 cf tanks, this cart is fairly overbuilt, with 1 1/2 x 3 x 1/8 rectangular tubing, 3 x 3 x 1/8 square tubing, and 1/4 plate as primary components. Most steel came from the scrapyard for around $20. The wheels were slightly more expensive. I had originally run the axle inside the frame, but didn't like the balance. So, I welded on external ears and foot bars.

    There's a haze of loose red overspray on the floor, even though I did the spray painting on a canvas dropcloth at the other end of the shop; it was bloody cold outside!

      A well designed and constructed O/A cart, among the best if not the the
      best I've seen.

          Thanks guys...

          I appreciate the kind words.

          Headnut, I had to look up Villa Rica on the map. Looks like you could make a quick run into Atlanta, if needbe. Heh, I so try to avoid that! I'm down in Columbus, and get my stuff from Jones, also good guys. I have been to Carrolton a few times, having bought my Kawasaki cruiser at CycleWorks, still more good guys.

            Nice looking cart, most people(myself included) throw something together to get by with. Having the intention of doing something better later.
            Good to see you did it right to start with.

              Very nice professional job. I would rather overbuild than underbuild then you won't have to rebuild (hopefully).

                    No chance . . .

                    No chance you would have dimensioned drawings, plans or more pictures . . .
                    I would really like to build one . . . It looks well balanced and sturdy.

                    I considered building one similar with the addition of a third point to the rear with a a small "dullie" wheel so it could be rolled without HAVING to support the weight. Like a small "wheelie" bar with a small dual wheel on it . . .

                    Not sure if making the "dullie" pivot out on it's own when ever the cart is leaned back in preparation for moving . . . Suggestions appreciated . .

                    Again, that is a very impressive looking cart . . . .

                      Great design, I really like it.

                      I esp. like the pins for holding the bottle caps. Neat idea.

                      You need a place to keep your spare tips. attachments, and striker, though.

                      I have two of the Harper carts for my tanks. They're too expensive new, but I got them used. They're downright cheap looking and feeling compared to yours.

                      Now, go get it dirty.

                        Many thanks

                        It's nice to hear good things from others.

                        I have no drawings, Steve. But, I sort of wish I'd kept the 3-inch Post-It with my original sketch. It would be kind of funny to scan and post.

                        I first decided how big the foot-plate would be. Then, how high up the 3x3 cross tubes would be for good support. After that, it was a lot of test-fitting as I progressed.

                        The wheelie bar idea is interesting. On a small cart like this, it might get in the way, since the hanging hose is fairly low. I suppose it would need a vertical arm with pivot attached maybe 16 inches up the center support, and hinged braces from near the wheels, with some sort of slide/lock that would allow them to prop the arm/wheel in place.

                        Yes, there should be some sort of accessory trays. I had originally planned to open up the top 3x3 tubes to have built-in space. But, after cutting one open, I didn't really like it, and feared the loss of strength. I'm planning to scrounge, buy or build a couple of trays to pop-rivet in place on those arms. I'm annoyed that I threw away a cheap toolbox that came with some cheap sockets -- red metal with hinged lid, just the right size -- after it got uglied up with brake fluid.

                          Wow! That is much more than decent execution, IMHO.

                          That that is is that that is not is not.

                            Do yourself a favor and rotate your acetylene tank 180 degrees to get the regulator out of the path of danger. You don't want that valve subject to anything falling on it, and right now you've added a lever.

                              (yes, it's a new setup)

                              Jim, I have since moved it 25 degrees or so to the front, having nearly clipped it at the side, while moving the cart. Being able to read the gauges from just the back side is an issue. Unlike the side clip, I can't imagine what would be falling on it. What do you have in mind?
