Jumbled Drafting Pics
Okay before you judge too bad, you have to understand that when a mechanical engineer and an architectural engineer brainstorm... you get some crazy napkin sketches. I will number these so they can be explained.
Okay so 1, this was a sketch of the bracing design for the tire, it shows how we were showing 2 tires are sometimes attached. The circle around the left part of the bumper shows where I cut it off and how the latch wouldn't be on that part so the welds didn't need to be great. This sketch is probably the one that will be closest to the final even though it is very jumbled. Number two is very hard to see but to the lower left of it shows the length of a jerry can and how I will be making a square on both sides of the swing arm to attach the AT jerry can mounts to so the cans will be directly over the swing arm to give the most support. Number 3 shows the jerry can holder... its really bad so don't try and decipher it. HAHA wow these are cluttered! Its amazing I can recall what they are! :Wow1:

This one is pretty easy. Nothing is to scale but all the measurments are accurate. This was to see how to mount the jerry cans. Found out that there is no way to mount the cans on their sides (this lead to making the square on both sides of the swing arm to support the cans) The final design will be 2 Adventure Trailers can mounts right next to each other close to the latch.

Number one is what I had originally thought for how I wanted it. The tire far to the right was just to explain something. Number two is how the arms would have to be to make more since and easier cuts since the design from number one was over complicated and had too many gussets. Number 3 was me trying to explain to my dad how the jerry can mount looks. Number four is how the plate the tire bolts to needs to be made. I was thinking the right, but that wouldn't be as strong as how my dad showed (the left) so we are going with that. Number five was what I thought would be perfect. Big strong arms for the tire. The gussets for the arms would also serve to bolt the can mounts to and everything would be great. The problem is to fit that with the jerry cans.... the tire would be over the roof line haha.

The reason I am posting this is to show anyone who wants to fabricate something themselves, that the design will change about a thousand times. Every piece has changed on this thing except the side of the vehicle I wanted the hinge and the hitch sleeve. There is a lot involved with a rear bumper but after the building today and the new idea to use the linch pin and stud to secure it, I think we are finally at a final version. I don't have 32" tires to mount up so I will have to use cardboard to space things out and just remember to give 10" of clearance from the tires mounting plate to the rest of the swing arm. But I learned that with this, taking things one at a time and being willing to change is a GOOD thing. Im hoping to have the wings done tomorrow and the rest will have to wait for about 2 weeks :/
Sorry im long winded.
Cheers!
