Overpass question. [HELP]

[Jon Stratis]

Take a look at the 2008 Game Specific Drawings from FIRST, available here:
http://www.usfirst.org/community/frc...t.aspx?id=7684

Specifically, you want to know the dimensions of pieces 06 and 07, which is the end piece that supports the overpass, and is described in diagrams W5 and W6.

W6 specifies a height of 76 3/8" from the bottom of the overpass connector to the bottom of the piece. This translates into 6' 4 3/8".

W5 describes the footing for the piece, which (if i'm reading it right) says the thickness of the floorplate is 1/8".

And as you've said, the pipe is 1 1/2" OD.

Add all those together, and you get 6 1/2' from the floor to the very top of the pipe that supports the ball. I would allow for some slight variation in your design, however - maybe give or take an inch.
