I hope that all of you had a fine Thanksgiving; we all have so much to be thankful for. I did spend a little time in the basement this week end, pondering how I might improve my machine for next summer. I would like to have it ready to drive in the 4th of July parade in 2012, in fact I have promised my grandchildren that they could ride in it. That is the way that I inspire myself to get something done, make promises that I feel obligated to keep. I have been toying with various ideas in my head for the last several months but now I need to get something on paper and then cut out of actual materials that will do the job. While last year the entire vehicle was made mostly from wood, to improve the performance of the vehicle for next year I will have to have a few parts fabricated from steel. Here is a quick sketch that I made of some parts that I need to lay out in CAD. I will make complete working drawings this year and post them on line for anyone who is interested in how to build their own rubber band powered car.
