Dunno if anyone remembers a couple weeks ago-- someone came up with the
challenge of building a working bicycle from Lego bricks (working gear shift w/
chain, derailler, coasting ability, etc), but I think I've determined that no
actual prefab Lego wheel is big enough to look proportionally accurate. Hence,
I'm playing around with making a bicycle wheel....
For the moment, my wheel consists of 2 8x8 octagons (2 plates thick) that
sandwich in a bunch of small technic connectors. On each of the connectors (20
in all), a 12-stud axle protrudes, forming the spokes of the bicycle wheel.
Hence, from spoke tip to spoke tip, it's about 32 studs across.
My question is: What's the best way to make the tire supported by the spoke
tips? I'd like it to be 2 studs wide (or maybe as much as 3) around the edge of
the tire, and I'd prefer a flat outside (studs facing in/plates/slopes/other)
My inclination is to put 1 stud long technic bushings on the end of each spoke
and attach 2x4 plates with holes to them along the perimeter of the wheel and
connect those (the plates) using some sort of joint en masse. On the plus side,
that'd be nicely stable, have studs facing out for a flat outer surface, and
'look' complete. However, I have a serious lack of 2x4 technic plates w/holes
and joints which could connect them all together (maybe not SW joints, but
those aren't quite well suited to the job). I spose I could just use regular
2x4's (not quite as stable), or short change the amount of connecting joints
used by only actually attaching it to the spokes at fewer points (the remaining
spokes being mainly 'decorative') but that's also less sturdy... Any cool
suggestions?

| I tried to make a derailer transmission a few years ago, but pushing the chain off of the gears just wasn't working. Since you brought it up, I had a new idea. I don't think this would work for anything much smaller than a 2:1 scale bicycle, but it (...) (24 years ago, 26-Sep-00, to lugnet.technic)
