I put on a good set of straps on my old TheMightyHobie18 some years ago. I started by making a trip to a car junk yard and pulling a good lenght of seatbelt strap off a wreck. Cost me $2. Using a hand awl tool with medium sized threading, I stitched a reinforced area on each end of each strap by folding the ends back on to the strap for about 3-4 inches, then stitching around the periphery of the overlapped part and then on the two diagonals acorss the overlap. I put a brass grommet throught this reinforced area, put a bit of line through the grommet and around the front beam, back up and ties to itself. At a suitable distance aft from the front beam, a couple of grommets were put in the tramp and a loop of line used to position the middle of the hiking strap. Some folks like to add a 2-3 inch lenght of 2 inch diameter tygon plastic tubing over these grommets with the line loop coming up vertically through the tubing, then around the hiking strap. This helps hold the strap off the tramp making it easy to get your feet under.This is how it's setup on my Tornado. The rear end of the hiking strap had the same reinforcing/grommet theme going as at the front end...tied off to the rear beam. Works great, is easy to adjust the tension to where you want it and can be easily swapped out later.
