What an idea! This might be something we all could use! Think about it...
Aluminum axles! Stronger than the plastic and just as light. Maybe an alloy
would work better. Of course, we're talking _precision_ machining here, but
it's possible...
What about aluminum gears, too? Someone has _got to_ look into this! I'll
take a look at Toys r us metal jewelry making kits, see what they can do...
Wow! Paradigm shift for me!

| (...) Look at something other than aluminium. Try the simple expedient of getting a piece of rod the same diameter as a Lego axle, you will find that aluminium is _very_ soft stuff, and will bend (and remain bent) far easier than the plastic axles.

| The thing to do would be to extrude the axles out of an aluminum alloy like 6061-T6. They would be about 20 times stiffer and weigh twice as much. If they were stainless steel, they would be 50 times stiffer and weigh six times as much. Regards, (...) (25 years ago, 9-Jan-00, to lugnet.robotics)

| After the good suggestions from folks (see the Balancing Bots thread) I did some experiments with using 2 motors to drive one axle (to double the power to the axle) and thought the results might be of interest to others. I first tried having the (...) (25 years ago, 7-Jan-00, to lugnet.robotics)
