modifying sprockets
 

The rules are unclear as to whether the sprockets may be modified to add holes for mounting. May we do this? RB 5 does not specifically mention the word sprockets.

Please clarify.
Thanks.

Sprocket Modification
 

Yes, you can modify sprockets. Just remember that, in OCCRA, the tools you use are restricted: consult the "legal" tool list in the rules. You may not use a mill, welder, lathe...etc., or any other machine not sanctioned.

Our big sprockets have holes drilled all around them in a swiss cheese look. It both looks cool, and reduces weight

Yeah, we won the "Beautiful Bot Award" in 2000 for those sprockets. They're nice.
