Well it's been real cold so I've only spent a couple hours every other day in the heated garage working on the 2 wd delta. Both drivelines are on the trike and all brake, shifter and electrical cables are installed. The pedal side is using a 5 speed and a short cage derailleur. I just picked up a 1/2" and 3/4" conduit benders and some conduit to make a seat frame. There is a learning curve to that for sure but I'm starting to get it. Probably be another week before I can try welding it up and setting it up on the trike. A friend gave me the seat fabric from one of those gravity chairs and that's what I'll be using.
