|The frame, coming together. At this point I hadn't yet drilled holes to attach the angled braces, so they aren't pictured.|
|The frame, plus DAT WHEEL. You know, for scale.|
I've got some pictures of mechanisms that I like a lot: first, unconventional 80/20 attachments, for unconventional 80/20 angles.
For the large angled 80/20, I drilled hole at a 20 degree angle into the metal, and then milled out a larger hole for the head of the screw to go through. The bottom of the bar is connect (as you can see in the second picture) with an 80/20 T-nut, and (as you can kind of see, in the whole frame picture), the top of the bar is connected by tapping the end of the 80/20 cross-piece bar, and screwing into that.
Second, I really like the kingpin steering mechanicism.
These milled-out aluminum blocks (right) will be the mounts for the front wheels. They will fit between the two steering plates and the bolt (left) will allow rotation about its bearings. The steering wheel, and rider control of the steering, will link to the blocks' bottom plate.
There will be pictures when this happens, and those will be a better explanation.
Next up: attaching wheels, both front and giant back, along with steering!
