Art,
I've been a fan of your designs for quite a while. They are always clean, organized, and very well thought out. Keep up the good work!

Some questions about this chassis in particular:

How much ground clearance is there?

If the game calls for an open front, do you have a plan for joining the frame members mid way?

Would it be possible to hex broach the Colson wheels directly instead of machining knurled inserts?

For the mounting hole pattern on the frame, I'm wondering if you could make them all 1/4" holes. This would allow you to choose either 1/4-20 fasteners, or #10-24, since 1/4" is the drill size required for #10-24 PEM nuts. So if you have a spot where you want to use # 10 screws, just put in a PEM nut.

I like the way you have designed in a series of holes to allow repositioning of the standoffs to serve double duty as chain tensioners. This is much more reliable than using slots to reposition a tensioner. Do you know how much excess chain length would be taken up for each position of the standoff?
