He seems like a cool guy, I've just had this kicking around for a long while now. I guarantee it's the reason there is only one running completed setup right now. Machining, welding, or fabricating a linkage system is beyond the realm of DIY for most, including myself. If this level of difficultly was known, I wouldn't have dived into this project. I guess I was just mistaken, figured this was the type of DIY where as long as you found and bought the correct pieces it could be put together. What gets me is I myself almost backed out, then got a bug up my ass and ordered it and had the plenum made. I'd of just sold it like many others have tried, but even on the used market these aren't really selling because of the linkage issue. The plenum would be hard to unload too.
Back to waiting... Ugh.
I'm sure it's not even Ken that lags, but T3. I guess that's the life dealing with small popular shops.
