Half a page is hardly long-winded and entirely what these forums are missing. Nearly everything else in this thread is pointless.
What we have here -- and what we often see on CD -- are pretty pictures with nothing substantive to offer. This thread is, so far, much of the same.
We see a bit of the criteria used in driving this design -- a desire to minimize machining time and to use COTS components. That's a great start. What's missing, though, are other goals and constraints -- speed, weight, cost, etc. Without first establishing those constraints, there's very little "process" going on and so, in my mind, there's not too much to discuss.
The next step is to fill in some of the broadly sketched strokes that take you from ideation to design. The wheels use purchased pillow blocks -- from what supplier? What do they look like? How are they fixed to the chassis?
How is the chain tensioned? How do you run chain to the outer wheelsets?
These things don't happen magically. This is where real design happens most of the time, it's the most interesting thing to discuss and it's the thing we see least here on CD these days.
Sorry to be Ms. Cranky Pants, but I've been waiting for awhile to see someone take the next step and offer real information describing how their pretty pictures came to be.
