Chain drive .... blowers?

at the time thats what there was and how they were first able to make such things work,,in time and with knowledge they refined it to more efficent and safer ,,They were bicycle and motorcycle chain,,no more dangerous than an open motorcycle chain really,,

so I don't see how you can make that comment..unless you are reffering to it being used in this day and age ,,and even now with proper safegaurds it an be safely used


in theory long as it has a proper cover its no different than a timing chain
