Alternative attachment of skateboard trucks, boa technology

Step 3 The foldable skateboard step, yet to be finished...

so thats the instructable on that part, its nice if you like to carry your skateboard in stores and stuff and dont want it sticking out a bunch, so you can take the trucks off real quick throw them in your backpack and then the deck can slide in your backpack and just hang out a bit. the foldable part is the hard part, and i think it would be the best part and make this project so much sweeeter. i was trying to use the BOA system to connect the board after making cuts in it...not the easiest thing to accomplish, check out the mess i made. let me know if you have any ideas on how to do this...
