“Sir Rodney” is a wheeled trebuchet with a fixed counterweight. He has been built to the same specs as Tiny – my swinging counterweight trebuchet – so that we can do some practical field testing. Sir Rodney has 26kgs of lead bolted to his throwing arm and seems very enthusiastic about this whole “throwing stuff” concept based on dry firing tests.
My co-defendants and I will be taking Tiny and Sir Rodney out for a full field test this evening when it cools off. There may be pictures… they may be on the news or in the papers, who can say.
Sir Rodney was designed the week that Jonny Hart died and is named after the goofy looking knight in Jonny’s Wizard of Id cartoons. I’ve always found wheeled trebuchets to look pretty goofy so hes stuck with it. No plan for a Gwendolen yet although there may be a Bride of Chucky in the new year.
UPDATE: Heres a couple of pictures I grabbed last night after we finished getting ready for todays school visit… the one I left the camera at home for.
But for those of you playing at home with a ballistic inclination here are some numbers for you to plot.
I’m not sure why a wheeled trebuchet would “more accurate” given that it has more movement for a start, but what it does have is more range due to a more efficient action with the counterweight falling as near as straight down as possible without wasting energy swinging around the axle. I haven’t plotted exactely how much more range yet but after one of our friends “fixed” him the day before I’ve had to do some retrograde work to get him back to what I like to call “functional”.
