O/A cart - something a bit different

[jamscal]

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.

It's nice to hear good things from others.

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 . . . .

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.

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.

[EdZep]

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?

Something with "Murphy" written on it.

[Fishy Jim]

You've never had anything fall on you? Off a shelf, off a truck, off another part you thought was clamped firmly enough...

Murphy is a real ***** when the braking force is explosive (braking as in stopping - not breaking as in broken).

Call me paranoid, but I would put a bar over your tanks to protect the valves from falling objects. Acetylene is no joke.

But, I don't see why it's more likely to have something fall on it there, that rotated around. And, with the gauges way back there, they could hit if the cart was driven right up to a wall. It seems that, any way you look at it, there's some risk to the gauges. And, most importantly, they have to be readable.

[Fishy Jim]

The first pic you posted with the gauges they were both aimed to the left. If you rotate the acetylene to the right 180, then both of them are inboard of the 4 sides. If something fell from above, it would hit your oxygen valve first.

As bad as having a 3000psi tank bust a valve off is, I would rather deal with the rocket than the big BOOM you would incur with the acetylene seeing the same fate.

How very true. An oxygen bottle will go through the roof of your garage and possible your house and be rocketing it's way towrds freedom in under a couple seconds leaving most of the place intact. Acetylene won't be so forgiving. It will level you'r house and destroy everything inside. Out of every tool and machine in a shop that can kill or mame you acetylene is usualy the most dangerous thing you will find.
