Garhauer's making my new traveler as we speak (OK maybe not actually making it, but it's in the works.) I'm getting great support from them.
This "simple" project turned out to be a lot more involved than expected, since I had to make a new teak traveler bridge. Because there are four mounting bolts for the bridge that run through the deck, a standard 4" spacing for the track screws won't exactly fit. No problem -- I sent Garhauer a diagram of the bridge, and they are going to drill the track holes exactly were I need them. And they are going to curve the track to match exactly the curve of the bridge.
One thing to consider -- Guido (he's the Garhauer traveler guru) said they're running about four weeks from order to delivery. Not sure if that applies for a non-special orders, though.
Once it all arrives and I get the whole thing done I'll post pics.
