Progress is made!

There were several things we found out today.  First of all, I picked up a used electric lawnmower the other day, and we've taken it down to just the battery and the motor.  It's a 12V, and since it doesn't have stats on it, we're assuming its about a 12A draw, and probably near 3500rpm?  Today I tested it on a known good lead-acid battery, and it works!  We were getting some lame torque and rpm out of it with the battery in the mower, hence the test.  Also we found a place that we're getting the square tubing from for only $.75 a foot.  Most of it's going to be 1" by 1" at 1/16th thickness, but we're also getting some 1/2" by 1/2".  The only reason I didn't get it today is because they only accept cash or check, which I didn't have.  So I know for a car this size, the frame is most likely overkill, but it allows for more messing around and upgrading later on.  Anyways, I'll get up some pictures of the tubing, when we get it, and the motor.
