I think I have to agree with mangle on this one Trailboss... I think after a couple of runs you will start to risk going right through that thing! www.pinkbike.com/photo/3443288
fair enough i havent seen many wooden ramps so i dont have a clue how there meant to be built. i guess we will find out when we start riding it. how thick should the ply be on the riding surface?
hey dan, i've been admiring your amazing dirt work for quite a while now, and would love to hit those jumps. as for building wooden kickers, we build a fair amount of them here in the rockies, and the first thing i see in regards to the one you built here is a lack of horizantal support through the columns of your kicker. as your columns go from the ground up to the plywood, i would have at least one more set of horizantal braces spanning across them, in truth, i might have designed some diagonal coloumns running from the base into the plywoodof the jump- in an effort to provide strength against the force that the rider will generate as they come into the jump. we never use plywood on our trails- realy we just harvest the wood from the forest- look on my or silent j's photo albums- but hopefully this booter will last as long as your other work does. cheers, obee.
ok thanks for the advice, there is a frame around the bottom of the uprights its just you cant see it because we buried it a bit to stop the ramp moving. maybe we'll put a horizontal brace half way up the uprights. I didn't build the ramp by the way.
yeh i think u should deffinatly put a support on there, like from the shortest horizontal support seen in this pic the one that only shows liek 2 inches, put a piece of wood from there to the middle of the last one, where that other 2x4 is that is the width of the ramp , that would help it out a lot
I think with another layer of ply wood wouldnt go a miss. Just wodnering how come you didnt build the sides out of play like this? www.pinkbike.com/photo/5027855 Also good job, looks like a pretty sick set up.
