Hm, that's not going to work
|
Unfortunately, I ran into a problem: my original design with two
welded support posts would completely trap the axle. There would
be no way to replace it -- or even replace a shredded tire --
once I welded in the posts. There's not enough room between the
front-to-back rails to twist things out. It's like one of those
stupid puzzles, except I don't think that this one has a solution.
Fortunately, I haven't yet welded anything in place (I wanted to
have the axles built in order to help with the alignment of the
posts). My new plan is to weld the inner post in place, and then
make a kind of bracket for the outer post, to keep it from moving
forward, backward, or inward. The layer of polycarbonate armor
will (knock wood) keep it from moving outward.
I've done some tapping of the holes (note the bolt in the upper
left of the picture). It's very relaxing work. I'm sure I'll
continue to enjoy it until I break a tap.
By the way, the camera I'm using to take these pictures is the
one that is included with Cosmopolitan Virtual Makeover 2.
I bought it on sale a local software store because I thought that
$20 for a digital camera was a pretty good deal. I may use the
software later to show my robot with a new hairstyle.
