rotisserie

i am going to build one and i was wondering if anybody has any ideas about it most people on here know about my smoker build and the tank will be only a little bit shorter i want to have a love joy coupling so i can take the motor off the mount so it wont get wet when i store it outside i plan on starting this in the next couple weeks i am getting a air compressor tank and a motor for free from the same guy who gave me my tank for my smoker so give me any ideas

thanks

the tank i am guessing 100 gallons and racks what do i need those for it is just a rotisserie not a smoker its just going to have a spit i already have a great smoker
