I can smell "retired NASA engineer has too much time on his hand".

You would have to be pretty good at steering it or it would be scratched and dented to **** real fast!

Steering is performed by dual linear actuators and spindles use timken tapered roller bearings for amazing strenth

That's the highest quality Craigslist add I've ever come across.The toolbox is cool too!

I've been thinking about doing that to my HF box for a while. We build one in college for our track box. It was hard wired like an electric pallet truck, but it certainly made moving the 1000lb box and two 120cf bottles a lot easier.
He has a really nice setup, but all that extruded aluminum is expensive. The solar cells are also about useless. How often are you really going to leave your box sitting around in the sun. I think you could replicate it as good or better for about 2k. I'm also concerned about how far you would get with only one battery. 100 amp hours at 12 volts is not a lot of energy. My motorcycle weighs about the same and it doesn't go very far with 120 amp hour batteries running a 52 volts.

I like it
if you have a race trailer it would make it easier to get it in and out

as far as cost, way too much

I'm grading on a curve:

Originality:10 points
Workmanship10 points
Design10 points
Is it cool enough to get me some tail-10 points:spit:

That's great and all but isn't this why they make service carts?

Hell no it's not ridiculous. That box is as cool as it gets. They did an awesome job of building that cart. I don't think a better job could be done. No detail was sacrificed, and the craftsmanship is second to none.

Nice job. Engineers build things like that because they can. The only down side that I can see is the Bosch tubing frame they just don't hold up to rough use.

I'm glad you posted that link, I am very interested in that "Bosch Rexroth aluminum profiles" used to make the base for that tool box to make a base for my tool boxes, I was just talking about it today with another member here how I'm not a big fan of welded aluminum but I want light weight, this looks like it might be of interest. If anyone knows about this stuff or a similar product, where to get it and how expensive it is I'd be interested in hearing, I'll probably start a new thread on it in the fabrication section.

I didn't see your post before I posted mine. Are you familiar with the Bosch stuff?

Yes, I am familiar with the Bosch tubing. It is not welded together but is assembled with a system of screws and brackets that are only available from Bosch. These tend to loosen in rough service. It is also expensive. It's big selling point is that almost anyone can assemble it and it does not require painting. It is good for engineering prototypes but in my experience it does not hold up well in the real world. As an aside, in my experience TIG welded aluminum with proper joint design can be quite strong.

An alternate reality in a parallel universe.
I digs it a lot. Mighty cool, would be great for an aviation tech or industrial tech who has to push their tool box a 1/2 mile to work on something. I do wonder that once you add 2,500 pounds of tools and put it through a bunch of racking if that frame will hold up, but you could always TIG it together for additional strength.

That thing is awesome. :bowdown:
Incredible workmanship....and complete overkill.
I would love to know the background on that thing.
Did you notice he is selling the Mac and keeping the Snap On . :lol_hitti

I just wrote him and sent a link to this thread.
I asked him to tell us about it, hopefully he will .

I saved the pics, I'll shrink them a bit and post them.

That's too bad I thought I found something that would be perfect. I wonder if Loctite would help with screws loosening. My experience with aluminum has been bolted holds up better than welded especially when the item will be racked like a toolbox going over cracks and bumps on a floor, but it was with a much heavier gauge. I've also had really good luck with heli-coiled aluminum. I'll try and see if I can find a local place where I can get a look at the stuff but if it's light duty with light fasteners it's most likely not what I seek.

2"x2"x.125 wall aluminum tube weighs 1.12 #ft. 2"x2"x .125 steel tube weighs 3.06 #ft. If you used 20ft the weight difference would be about 40 #. The cost would be about 3X. Only you can decide what's the best way to go.

Hey everyone,

Thank you for taking an interest in my project. Bart Simpson wanted to know a little about the projects conception.

Not NASA or MIT. I'm just a guy with an imagination and a machine shop in my back yard. It may be rediculous to some but for me it was a 100% practical application for the work I do.

Whats rediculous is the motorized bar stool. "Lets get drunk and go 90mph".

I am a Facilities Engineer for a semiconductor company in Tempe, AZ. I work in several differnent facilities so I am always dragging my tools around. I bought the long Mac box so I would also have some work space on top. Now if you have ever rolled a mechanics box on asphalt you know its horrible. Its hard on the box and your tools end up everywhere. So, originally I was going to build a cart with pneumatic tires and a pull handle to give me a smoother ride. Then I thought about the weight I would be pulling and how difficult this would be on a grade. That idea evolved into the idea of adding a motor and making it similar to an electric pallet jack. Then that idea evolved into adding the remote. There you have the results. Someone suggested to me that I should add voice command which is not that difficult with todays selection of devices but I had to draw the line somewhere.

Now as one poster commented on the Bosch material and how it would rattle loose over time. I have worked with this material for several years and I have never had an issue with it. With proper design and the correct use of connectors you should never have an issue. I designed the frame with only 4 load bearing rails that do all the work. The rest of the frame is mostly cosmetic. and as far durability goes I think this is a non issue unless somone is going to run the BAJA 1000 with it.

Now, I spent 10 years as an aerospace machinist and 8 as a design engineer so overkill is usually a given with any of my projects.

I spent 8 months on the build and during the process I realized that it was turning out way too nice to take to work. So now I am looking for a new home for it.

Someone spoke of the solar panel. Although it is completely functional, it was more of a novelty add-on. And you are right, no one is going to park it in the sun to charge it but the nice thing about monocrystaline panels is that they will charge from artificial light also. My panel still produces 11-12 watts from fluorescent or high bay lighting. Plus, its a lot greener this way.

Someone was asking about access the the bosch framing. You may have a local supplier or it can be ordered directly online from Bosch Rexroth. My local distributer in Phoenix is Pacific Integrated Handling. Be warned this material is sold by the millimeter. the cost for my frame with all hardware was over $1100. But the best feature over welding is that it can be easily be altered and thats a blessing when building a prototype.

Ok, this is getting long. I have enjoyed sharing. if you have anymore questions feel free to email me. I am currently working on a you tube video which is about 75% complete. I am waiting to install the side panels before I shoot the rest of the video. Everyone will be able to see it in action.

Planet J, i have to applaud your craftsmanship- the chassis looks incredible, well though of, and obviously expensive to build. I do feel the box is worth what you are selling for, there will be someone who will jump at the chance and say "exactly what i need!"

My box gets moved to clean under it approximately once every six months, other than that it sits in once place. So this is not for me. But i can definately see a person who works in a very large shop, and is constantly wheeling their box around, jump at the chance.

good luck selling!
