Here's my latest submission: a full size model of the STAR WARS Speeder Bike based on the AMT/Ertl 1/6th scale model. I took all the plastic parts and scanned them into my computer and then with a program called Apple Works scaled them up to full size. Apple Works allows you to print them as an adjoining patchwork of prints that I taped together to use as patterns. Most of the thin flat shapes   were cut from MDF (medium density fiberboard), most of the tube shapes were made from PVC pipe, structural tubes were steel and the larger round shapes were sheet metal. The body and side pods were sculpted in urethane foam and coated in fiberglass resin. The seat is the only thing I had to have made by an outside source.

Once I had the parts scanned I built the model to use for reference - comparing it here to my progress last fall. I originally had planned to use an old child's bicycle with a lawnmower motor to power it, but for a number of reasons that became an impractical solution in trying to motorize it. Later, I adapted a 'power chair' for a tractor drive (not shown) and works very well, but its large bulk does detract from the aesthetics

I haven't totaled the hours, or the cost of material, but let's just say it's the most expensive model I've ever built. Movie available on YouTube.
