Jamboree Rack Design

Great Job!
My observations, as architect:
1. your are creating in some way a path to direct all the weight going down (as static structures should be) but remember, all the weight is "failing" on the four bolts, and there is a lot of different forces compression, extension and torque, every time that you brake, press gas, gravity, overweight, different distribution of weight, etc. my humble opinion is that for your door life, you should put over the less weight as possible in this ingenious rack, and use rather of that the roof rack for heavy weights. Orr builds inside the door a multi-forces-receiver stainless steel bar mesh.
2. At the end is not bad at all over calculate the structure in this case because who cares about 3 pounds more in a hummer, but I?m really sure that right now you can stand up three 200 pounds guys on that rack (if you are using stainless steel as I can see, maybe is aluminum and I?m wrong.
So, now you know, in the next engineering project: less metal and better forces study
Anyway looks practical and ingenious.
Keep inventing solutions, not everybody put dreams in real life, you need ba.. to do it. I love to see guys like you bringing solutions to real life

Thanks for the comments, I had a chance to use the rack at full load over the weekend with two jerry cans and full cooler. Wheeled on Drummond Island ORV trails and I can tell you that if it was goin' to fail it would of then. I have a little experience in load calculation, rotational forces, modulus, static load, etc. This proto type is over designed and I have revised plans that shave about 10# off the rack itself. I'm pleased with everything so far, we will have to see what time brings.

Well after almost a year rack and rear gate are both doing fine. I certainly used the rack as expected this past year with close to 6 weeks on the road/trail. I've had several inquires about having some made for other members, not gonna happen but I will send link to plans and instruction for a nominal donation to cover R&D. These are high quality plans and instruction that any competent fab shop would be able to build from.

If you interested just send me a PM....

After getting these plans, all I can say is WOW! Very detailed, very professional! Great work!!
Can't wait to get this put together and on my rig! Thanks Paul!
