The "R.P.D.O. mini II"
These aren't yet the final mini halfpipe plans, but for many of you it may be all you need. We don't have or know how to use any CAD programs. So our guy fess used Adobe Illustrator to draw up a series of diagrams. [ No small task. ]
- 4 3/4" 4'x8' sheets of plywood
- 42 12' 2x4s
- 15 1/2" 4'x8' sheets of plywood
- 8 ~1/4 or 3/8" 4'x8' sheets of surface material. (plywood, polyboard,...)
- 1000 screws.
- 2 12'x 2 3/8" o.d. pipe (galvanized or black pipe)
At some point, we'll be working on maybe a few more diagrams and then writing step by step instructions to go with them. we're hoping to post as the whole set of instructions and diagrams as a PDF file so you can just print it out all nice and neat. ( Rick Dahlen clearly beat us by a mile on that with his awesome plans in the from the web section. )
so.. we're working. and all you little grommits who keep whining at us for being slackers. Do something with your life. Learn a CAD program. if you all ready know CAD. Design a ramp. Send in the plans.
when Don B, who had just finished building his new mini with a 66" radius, warned us that, with a 64" radius, our ramp may be too tight for most folks. We went ahead and knocked out a quarter pipe at that radius and while it's not that bad it's pretty steep so you might want to adjust the plans for perhaps a 72" radius. just to make it more generally tolerable. Eventually we'll make both versions available. We also are going to adjust the plans a little bit to make the plywood surface line up with less scrap.
every time you pester us we get a little more motivated. and we'll get these done soon. enjoy the preliminary plans.
