this instructable is about how to make a fast sled with simple items and in only 10 steps. this is great if you broke yours and all stores are out. I made this after my sleds couldn't handle my ramp after about 100 times and broke.
Step 1: Materials
1 black garbage bag
1 thick box
colored duct tape (optional)
Step 2: Open Up Your Box
If your box is closed on one side then open it up. it should look like the picture above ( you don't need to cut it round, i started with it that way).
Step 3: Fold the Box
take your exact-o knife and cut the sides of the box (shorter sides) about half way through and of as close as the middle as possible. cut off the flaps on the sides with the scissors or exact-o knife. shove in on the sides that you have cut and push down on it.
Step 4: Tape It Together
1. pick which side will be the front
2. fold up the top flap in the front and tape it down
3. take the bottom flap in the front and pull it up to a 45 degree angle and tape it down so it will stay that way ( it needs to be able to handle a big hit).
4. tape the sides down tight
Step 5: Cut the Bag
Lay the bag on the ground and cut the sides and it should look like the picture above
Step 6: Fold the Bag Over the Back
put the sled on the bag (the middle of the bag should come right up to the tip of the sled). Fold the bag over the back of the sled and tape it down.
Step 7: Fold the Bag in the Sides
stuff the bag in the pockets and tape it down.
Step 8: Fold the Bag Over the Sled
fold the bag over the sled and tape it to the sides. You can cut the skirt or keep it on (i cut mine off)
Step 9: Tighten Up the Bottom
stretch out the bag on the bottom and tape it so it will stay (i did a bad job).
Step 10: Finalize
use the colored duct tape and decorate (optional). test out your sled and HAVE FUN!
