Very rough, std 2pi is around 1.8ft3 / 50 L, tower 4.5 ft3 / 128 L
And Matts I like the trojan horse plan. We slip the tower in there as a gateway drug and once the monkey is on his back I'm all set! Problem is, his gatekeeper kaboshed it getting in the door. Good thinking, though. Gotta scheme more...maybe I build the towers to spec and lug them somewhere so he can hear them and then it's his problem to get them in his door.
And it's not like I'm any philanthropist--I broke my leg and couldn't drive (clutch foot) and he bummed me an auto-trans truck so I owe him.
