Free Mini Halfpipe Plans

Height	2' 8" (will work up to 3' 6.5")
Width	8' (will work from 4' to 16'+)
Length	25' (will work down to 17')

Here you will find free ramp plans on how to build an outdoor mini halfpipe. The halfpipe shown in the pictures is 2'8" high, 8 feet wide with an 8 foot flat bottom and 3 foot platforms. We used treated wood to build this pipe, which protects the ramp from the sun and rain. If you are building your pipe outdoors, you will also want to do this. I realize many people will not be surfacing with skatelite like we did, so you will need to read about your other options here.

Materials required

Quantity	Material	$(1 unit)
42	treated 8' 2x6	$5.97
5	treated 8' 2x4s	$3.69
4	treated 8' 2x8s	$5.99
12	treated 8' 1x6s	$4.97
4	treated 8' 4x4s	$8.97
2	(3/4)" treated plywood (4'x8')	$37.97
12	(3/8)" plywood (8'x4', not treated)	$11.99
2	8 feet long 1.5" diameter metal pipe	$18
1	(Optional) roll tar paper	$10.93
6	(Optional) 4'x8' skatelite	$150
6	(Optional) 4'x8' (1/4)" massonite	$10.99

Total Cost

Using Skatelite for surface	$1550
Using Massonite for surface	$716
Using plywood as surface	$650
Indoor mini halfpipe (see adjustments below)	$450

If you are building this halfpipe indoors, treated wood is not necessary (it protects from sun and rain). 2x4s can be used instead of 2x6s for the support beams, and plywood is sufficient for surface.

These prices are taken from a Home Depot in Minnesota in 2004.

Not included in the price is screws and tools (or tax).

If your materials cost $650 and you split the cost 8 ways, it would cost $81.25 per person (how to divide 650 by 8 with long division).
