| Ramp Plans Continued |
| Okay....you now have all of your sidepieces cut out and are ready to put in the 2x4 ribs. These cross braces are essential for supporting the skate surface and giving your ramp stability. First determine how wide you want your ramp to be. Next subtract how many sidepieces you will have in your ramp from the lenght of each rib. If you build a quarterpipe section with two sidepieces you will have to subtract 1 1/2 inches from the length of your ribs. Example: You want a 6' wide quarterpipe. If you cut your 2x4's down to 6' you would still have your 3/4" sidepieces hanging off each side. POINTS TO KEEP IN MIND: Always space your 2x4 ribs 8" apart AT MOST!!! If you spread them out more than that you run the risk of breaking holes in the skating surface or having sections sag. Never put your 3/4" sidepiece more than 6' apart. You might be able to spread them 8' apart with 2x6's, but you need lots of support under you skating surface if you want it to last a long time. Another good thing about keeping your sections no more than 6' wide is that they are much easier to work with and transport if you have to ever move your ramp. |

| Well....now you know how long to cut your 2x4 ribs so go ahead and cut them. Next prop up two of your sidepieces with a couple of chairs and secure a 2x4 rib in each of the 3 corners of the structure that now somewhat resembles a quarterpipe. This will make the assemblage somewhat stable while you attach the rest of the ribs 8" apart all along the curve. You now have one quarterpipe's structure complete. It is probably 4-6' wide and you probably have a few more to build so just keep repeating this step. NEXT you need to build the flatbottom. |
