Shaky Legs

One of the problems that I ran into during my test outing Tuesday was that the legs had worked loose and would fold forward during acceleration causing the wheels to slip or the front casters to bind up.

I tried to tighten the bolts by hand to no avail. I took advice given and put a hex like tip in a ratchet, which I quickly broke (leaving about 1.5" of broken tool down in the leg).

I found myself wishing I had an aluminum plate to make some sort of bracket, but since that wasn't an option, I resorted to more creative means.

I reached for the trusty cutting board used for the foot wedges and created inserts for the inside of the frame where the 2-3-2 motion would be (pictured below).













With the cutting board inserts in place, there is very little play in the legs and now R2 does a little wheely when he accelerates fast.
