Notes

Ramp built in June 2008, 8ft wide, 24ft long, 7ft radius, 39 inches high. Using 2x4 and 2x6 lumber, 3/8" and 3/4" plywood. Joist hangers were used to support 2x6 on cross rails, plywood floor under each end deck for storage. Leveled on blocks, sections bolted together with 5/16"x4" bolts. All material painted or sealed underneath for weather protection and dry rot. Used treated 2x4's where material is in close contact with the ground. Sealed with waterproof sealer, two coats. If this doesn't work, will coat with several coats of spar varnish or skatepaint. Utah has hot dry summers and cold wet winters. Total cost for ramp was $700.00 dollars give or take a few. Have enough material left over to fabricate a launch ramp and a grind box.
