Put your summertime boredom to good use.
I wanna build a rail this summer and need your advice. I plan on putting interchangable legs on it, 12-18 inches for skating in the summer, 2-3 feet for jibbin' in the winter. Have a few ideas about how to build the legs.
The thing I need help with is the length. I want to make it in 2 sections so it's more easily transportable. I'm thinking 2 8-foot sections, but am having trouble with the seam.
For skateboarding, the seam doesn't have to be perfect. But seems like a ski or snowboard edge could snag pretty easily on something, so wanna get it right.
Ideally it'd be a double-barrel, but using 2 piece of tubing side-by-side may make it more difficult, so I can see myself going to square.
Anyone have any thoughts about how to make 2 tubes that can be joined and separated w/out making much of a seam?
Thanks,
J-

Putting a rail into two sections is going to be a pain for snow. It will totally grab at your edges, which is 0 fun. What you might have to do is grind the seam each time you weld it together again - lots of camps do that to their rails every summer, which can be a drag.

Make a male and female joint with a connector underneath.

make it a kink rail (although you may not want it for skating) and then you can just have the seam at the bend. I don't know if it would work, but thats what I'd do.

couldnt you just make the rail a little uneven but make sure the higher end is the first part, you would barely feel the drop if it was only like half a centimeter down and your edges wouldnt catch.

for no welding and no drop, i have an idea. i'll post a pic in Misc and it can show it. Just put another piece of tubing with outside diameter equal to the inside diameter of the rail tubing inside one end of the rail (it has to fit really snug to the inside of the bigger tube). somehow weld this in place from inside the tube (not the visible connection). Then all you would have to do is slide the other section of rail on to this 'peg' once it is on, make them as close together as you can, and then file the seam. this should create a pretty flush fit, if the 'pegs' are long, and snug enough.

why make your own rail when One twelv rail deisngs can do all the work for you ?..... www.1twelv.cjb.net

the dr has got it, my rails are 10 foot tower sections that can be easily join and disconnected adn you can't really feel the bump when you cross a section.

Yeah, I like the Dr's idea. I think for this round I'll just make it 15 feet solid with interchangeable legs. Turns out you can put something that size on top of a car.
I like the idea of building connectors so that you can make kinks at the connection.
Thanks,

The 40' rainbow rail used in the Rossignol Air Tour, dissasembles into several pieces small enough to fit into a 10' trailer. This is how it is done:
the legs connect to the top part by sliding into a post that is welded on, and then held in place by a spring-loaded pin. The top of the rail slides together in several pieces with male-female ends, (with smaller posts welded on to connect them). one piece is just slightly smaller diameter than the previous one buy a millimeter or two, the two pieces can be connected by two tabs that hang down beneath the rail and are temporarily bolted together.
now go jib. I hope that was easy to understand.
You should belive everything you read on the internet, it's all true.
