Just finished building this using:
1 Very adjustable Radial saw
1 Table Saw
1 Jig Saw
1 Skil saw
2 Drills
approx 2 8'' X 12'' X 12' Pieces of treated lumber (got it really cheap)
Other various lumber scraps approx 3.5'' X 3.5'' X 4'
1 Honda Del Sol passenger seat
Various Nuts/bolts/washers and a box of 3'' Wood screws.
Took me about 16-20 hours to create using trial and error and only a rudimentary understanding of carpentry.
I ended up having to lower the pedals a bit to where they are now because they were higher than my heart before and it made my feet go numb-like after 30 to 45 mins of racing.
