1st You Get a ruler. then get 8 little squares of cardboard and tape 4 of them together and cut a little slit in them. Then do the other 4. Then put the ruler in the slits and theres your rail. Or............. You can just use some normal sized Skateboard trucks and take the wheels off
get carboard rap it around a pencil and tape it drill a hole in the pencinl so it will stand up
You can buy skate parks or make pieces out of household things. you can make a pretty good rail out of a pencil atop 2 Popsicle sticks, or you can carve things out of wood.
You can find a standard height of a deck rail here at see below link.
The standard height for deck ailing is 3' to 3,6"
36"
the railing on the forecastle overlooking the main deck
You can edit the deck plans that you are using to make the deck look different. For example, you could build a different hand rail that looks better with your home. It is important not to change them structurally, however. You do not want to make a small change that causes the deck to be unstable. This is especially true for decks that are suspended in the air on tall posts or on pillars.
My skateboard is on the rail.
The standard height of a hand rail is thirty-three inches, with an acceptable range of three inches in either direction. The acceptable height for a balcony or deck rail might be different.
It may be different for a balcony or deck hand rail and a stair rail but for stairs, the ideal height is 33" with an acceptable range of 3". In other words it can be anywhere between 30" and 36" above the nose of the tread to the top of the rail. But if you want to be sure and be "legal" in your area, check with the local building inspector.
You can't craft a rail. Because there isn't any rail in Minecraft classic.
