A little artwork while I was thinkin'
I first contemplated using 4' round tube but, it seems like it would be easier to attach to flat surfaces
IDK it also just seems like round tube would twist more
Then, I was leaning toward 4" x 4" x 1/8" square tube (~6.5 lbs. per ft.)
But, the 12V 12AH batteries, being 4" wide, would not fit inside a 4" square tube (~3 3/4" ID.)
So, now I'm thinkin' 2" x 6" x 1/8" rectangular tube
...it's also ~6.5 lbs. per ft. (same as 4" x 4" square tube)
...but, I can cut out 4" (for the batteries) of the 6" wide tube & still have ~1" of steel wrap around to help maintain the "rigidity" of the backbone
Front Axle, could be made of 1" x 3" x 1/8" steel, ~18" wide
...proportionally reduced from the backbone dimensions (2" x 6" to 1" x 3")
I am thinkin' of leaving the axle as (1) piece, cutting 1" x 3" slots on each side of the backbone & running it right thru
...the left side axle stub would be 6", the backbone is 6" wide & the right side axle stub is 6" also (kinda of a 1:1:1 ratio)
Rear Axle Housing, could be made of 2" x 1/8" round tube ~14" wide
...it could cap off the rear end of the backbone
I am thinkin' of running the 1" axle thru it (like a true backbone chassis) & just having the bearings mounted right on the ends
...the left side axle housing would be 4", the backbone is (of course) 6" wide & the right side axle housing would be 4"
...the sprocket could be mounted between the bearing & the wheel, on one side
...& the brake rotor/drum on the other side
May do a mono-shock type suspension in the back
Still thinkin' on that one
