you may use any cylinder on the form. all bimba's cylinders are custom and normal stock items. any cy;linder not on the list will be rejected on inspection. you may not use any others than the list. some teams in the past have used 1" bore and 3/8" bore and have passed inspection because the inspecters are looking mostly for safety issues. it is up to each team to learn the rulesand follow them so as to live up to the spirit of FIRST. no one that i know of has intentionally used any illegal parts. some teams have been called to the carpet for the wrong cylinders and were not allowed to use them in competition which nreally hampered the function of the design.

isuggest that you really redesign now and get your design to work with the specified cylinders.

any q's e-mail me and i hope this helps
