Rudder carnage





Hey, this raises a question I've been pondering:
At some point I may break a rudder housing. I hope not. I never have before. But if an when the day comes, I'm kinda screwed. Not too many P-Cat housings lying around.
But I work in a machine shop. Structurally, it seems like a win to make a new housing out of two side plates and a central "spine" where the rudder pin goes. It could be a weldment or a bolt-together. Either way would work. This would also open up a lot of choice in materials. Even staying inside the aluminum family, using something like 7075 or 6061 that's been lightweighted on the mill would make for a light housing that's unlikely to crack like that.
Aside from class rules issues (which I don't really run into with a cat this old) are there any unseen problems doing this?
Thanks,
Tom

if you got da skills, time and gear... it is a win for sure.
i was at dinner last night with a friend who was a spar builder/welder. He is currently borrowing one of my spare upper castings because his blew out just like Headhunter's did.
He wants to build a jig and make some but he doesn't have the time.. and if he did you are still talking a 6 - 10 hours to get the prototype out of the jig.... He would have to make / sell many sets to justify the time needed... and he isn't in the rudder business (anymore)
