its a shame that someone feels the need to take someone elses goodwill and then steals the idea to try to make money from it by passing it off as thier own.
I actually dont have a problem with him trying to do that...within reason. At the very least he should have contacted simul8r and asked permission. If given, then game on. If not, he should have attempted to develop his own pvc idea for sale and not take/use someone elses original idea. Putting wood over a 95% exact copy of an idea does not constitute any sort of original idea and at least as far as I'm concerned is stealing.
Ultimately, this is why there are so few options for plan ideas for building your own cockpit. When I started researching this idea so I could build one of my own, I was petrified of this exact thing....I'd see tons of ideas, but NO reference material or explanation on how to do it because people were more worried about how to line their pockets. Fortunately that only proved partially true, and not completely. I'm extremely grateful that Sim put his plans up so others could try it and when I posted questions and eventually pictures of mine completed, I gave him and Eddy complete credit and my thanks.
