I built this snow luge yesterday, because I could not stand waiting for summer to come around again. I have not tried it yet, as I am planning to do that today. I build it mainly off of the design of my "Street Luge" that is shown in a couple of other instructables. On the last step, I say what other modifications I have done to my origional Street Luge.
Step 1: The Materials Needed
To build this, you need
-scraps of 2x4
-a skateboard deck
-a cheap "snow play board thingie"
-a bunch of screws
-a small bit of pvc
Step 2: The Main Base
To start, lay down the 2x4 and cut it down so it is slightly taller than you are. Find out where you are most comfortable sitting on it. You can look back at my other instructable (Street Luge #2) if you need more clarification. Then cut the plywood to size, and screw it onto the 2x4. I used some plywood, and the middle part of the snow toy thingie.
Step 3: The Back Rest
Screw the scraps of 2x4 to the main piece on the shorter side of the 2x4, (divided by seat.) I used 2 pieces, but it can vary depending on how steep you want the backrest to be. Lay a piece of plywood against the scraps, and screw it down once you feel comfortable leaning on it while sitting on the seat.
Step 4: The Foot Peg
I forgot to take pictures for this step, but it is self explainitory. Take a scrap of 2x4 and screw it on to the main one near the front. Sit on the seat and outstretch your legs to detirmine where to put it.
Step 5: Handholds
I used a small piece of pvc pipe right before the plywood seat, but you can use anything.
Step 6: The Back Sliders
Take the cheap "snow toy thingie" and cut it in half. Attatch both parts to a scrap piece of 2x4 (about 2.5 feet long) and then screw the 2x4 to the bottom of the main 2x4.
