Glossary

A long time ago Mychael Jones suggested we add a glossary to the site. Well this is it. If you have any new terms or a better definition please let us know

• 

• Deck

  The top portion of a halfpipe behind the coping that you stand on. Also called platforms

• Flat, Flat Bottom

  The the lowest flat portion of a half pipe. The floor portion between the transitions.

• Radius

  the length of a line segment between the center and circumference of a circle. So for half pipes that circumference is the transition. The longer the radius, the more mellow the transition. [ still don't get it? ask a trig teacher. ]

• pseudo-ellipse

  any curve approximating an elliptical transition that is not actually an ellipse

• CAD

  Computer Aided Drafting. Any of numerous drawing programs that help you make technical drawings showing how to build something. they range from 2d line programs to 3d packages that can render photo realistic images. but all of them are geared toward generating diagrams with measurements.

• CAD Drawings

  Diagrams with measurements, that show the shape of a ramp or part of a ramp. and more importantly the measurements required to build that ramp.

• Transition

  The curved portion of a halfpipe. It transitions you from the flat bottom to the vert.

• Coping

  originally this word is "brick that is laid sideways at the top of a wall" which came to mean the lip of a pool, which then turned into anything used to make the lip of a ramp. Often, metal pipe, or PVC pipe.

• bevel

• Lip

• The point where the transition meets the deck. often where the coping is.
• The point where the transition meets the ground on a quarter pipe or other street ramp.

• Vert

  The vertical portion of a half pipe. (if it goes that high. a ramp generally only has vert if it goes
