Jesus kid, all of the stickies are explanations on how to build shit, pay a little more attention.
wrong, 3 screws will not hold it good.
for a 10' piece i did about 6 screws. You basically drill a hole in the top of the PVC that is as big as the head and then you stick the screw down that and drill inside the PVC, your skis wont catch on the holes and its the most effective way of holding PVC down to wood
This, He is right, it wont mess up your slide at all I did the same exact thing and I couldnt tell when I went across the holes. Do it, it will work.
im not freakin out brah.
I'm just stating the obvious, sealing down something in more spots is better than fewer spots. If you hit your jib alot 8 screws will hold it together better than 3. I've built both types of rails, my first pvc for rollerblading had about 4 screws and my new one for skating has 9 (1 about every foot or so) the one with 4 screws eventuallly wiggled its way out of the 4x4 and i had to rescrew it elsewhere, the 9 screw one is still going strong.
