start ramp build
I started on building a start ramp (good to have for the occasional outlaw and practice as well). So far, the process is going well. The sides are 3/4 ply with 2x4 bracing. The bottom braces are on 10" centers and the "S" braces are on 6" centers; 2.5" exterior grade screws holding everything together. I had read of smaller "S" bracing being perfectly fine but, for my piece of mind 2x4's wouldn't hurt. I did have to make some size compromises so it could fit in my car. The width is 32", length is 5' with a height of 31". I'm pretty happy with the transitions. They are drawn out due to the height vs. length so (I'm hoping) there isn't a noticible bump at the bottom.
I decided on using 2 sheets of 1/8 slick board (I'm sure there's another name for the stuff). My question is: What would be the best method to attach it to the frame. I was thinking of galvanized roofing nails because of the flat head but, would screws be better?
