Back to the super secret off-site shop for a project that I have been dying to see completed -- a tall bike! I honestly felt like a kid helping his buddy with his first bike. The anticipation and excitement were overwhelming. But let me calm down and recount the events.
Dave has been talking about doing a tall bike for a long time. There of course is not really a bluprint for a tall bike. There are many example out there. That's kinda the beauty, people get to design and express there creativity. Dave had a unique idea for the steering...we'll get to that in a bit. A welder and experienced metal worker was needed to bring the vision to life, enter Tom.
After much discussion and planning, Tom went to work welding the 2 frames together. In less than 2 weeks, frames were joined, a custom swooping seat stay was added, a fork was cut and bent and chainrings were welded on for steering.
After machining, Dave sanded and painted. With the tall bike ready for parts, he asked me if I wanna come over and help with assembly...HELL YA! Obviously Dave was excited too, as there were already some parts on the bike when I arrived.

Many tall bikes just weld the 2 fork up and have 1 continuous fork running through the 2 frames. Much simpler design. But, in doing so the bike's center is set back further than normal. The rider is situated more over the real wheel causing the bike to be somewhat rear weighted.
Dave's design called for a 4" offset. After assembly, the handlebars ended in almost the same relationship to the wheel and fork as it was when it was only 1 bike. This should create a more stable and predictable ride.

of the bike.
With the front end done, it was time to assemble the rear of the bike. Dave built in a drum brake for the rear wheel. Routing the chain was easy, but the chainline looks crazy!
Here are a couple final pics. We ran out of steam and Sierra Nevada so the brake lines will have to be added later. Obviously, there were many more small details that went into this project, I've merely bored you with the bigger ones.
