A good thing about being young is that you can learn from the older people who have the knowledge from trial and error and years of experience under their belt. I would love to see the Plexi car/truck on it first run. If it is cracking while cutting I am sure it would be awesome to see the first run. I imagine it would be like taking an old glass five gallon water jug filling it with screws and bolts and throwing it down the street. I do admire your ambition. I look back at some of the things I tried when I was younger and had no money, and think what was I thinking! I still don’t have any money and still not sure what I am thinking so maybe you never grow out of it.
