BUT... dont use plywood for the surface of the drop in. the friction will be much larger causing you to go much slower than if you put down 2x4s perpendicular to the riding direction (look in the cult for better directions). and just go to home depot or lowes for that shit, back in the carpet section you will find a bunch of different types of turf. just get the cheapest one, mine was something like $0.45 sqft.
ok so um i bought a sheet of plywood and i think i am going to return it but the problem is that i am working on it in the school and i'm afraid my teacher will get mad if i return this so got any excuses on what to say to him that will convince him to let me or not get mad?
Did you even read my post, or anyone elses? Using plywood is dumb, i think anyone above a 6th grade education knows that less surface area = less friction. There's a 10+ page thread that is stickied in the cult dedicated to posting a pic of your drop in, im sure you can eyeball something from that.
