My first attempt at building a close replica of a top fuel drag engine. I used balsa wood, bondo , household and shop items to simulate pulleys,nozzles and such. It took me 4 months and 6 hours a day to take it to where it is today. I intend to scan it to a cad file, then produce 3-d parts. Once perfected, I will then look for a plastic ejection company to make plastic models for distribution.
