Usign a 2-1/2 bore, 24" stroke pneumatic cylinder.

[BotDesigner]

Hi all,

For scaling we are planning on using a single pneumatic cylinder to lift our bumpers above the low goal. We need a 24" stroke, but I am not sure what size bore to use. Assuming that we have the necessary air tank storage space, would a 2-1/2" bore be faster than a 2" bore? I have read on this thread ,http://www.chiefdelphi.com/forums/sh...light=cylinder, that increasing the bore size of the pneumatic, although it increases the strength, makes it slower because of the extra volume that must be filled by air traveling in 1/4" tubing. Does anyone here have experience with large pneumatic bore sizes?
