thanks Bruce, good point about the leverage on it. The tube section on the chute attachment in reality is probably going to be 3" long and the stepped (solid) sleeve inside will most likely go the full length. The piece on the chassis is about 2" and will also double as a push bar mount for cackle events (I say cackle, we're on alky, but a fat pill and retarded ignition should put some flame in the pipes...)
