Probably between 100 to 200 dollars depends in where you get the wood
itll take some money but just make a down ramp on s medium angle and a then a quarter pipe
there are 3 big pieces that u need to hold together using the rods in the kit {u clip them into the bottom.}
You could sell a nice quarter pipe on ebay for 100 or 150 dollars. The person you are selling it to should be close enough so they can pick it up themselves.
90 ( 1/4 of 360 )
It equals 3/4" in length.
type it in on google and find out.
the cheapest is around 400 bucks
Every time! lol Seriously a 10-inch pipe is 5/4 of an 8-inch pipe
If you had been advised why ask again?
3/4 inch steel pipe if making a strong double layer frame.
For proper fall. Pipe should slope 1" for every 8'.
