Looks good, any specific reason for the negative headstock/reversed fork?

Well, on on normal bike, when you are stationary and let go of the handlebars, they tend to turn fully to one side. If you make the rake the 'wrong ' way round, with say 4 cm trail, it straightens the steering to point forward. This helps stabilize the bike. When you are riding along and the bike leans to one side, it tends to steer the way you are leaning, which makes the bike sit up again. It makes it more stable than it should be for quite a long, low bike, with little wheels. So when the rake is in the opposite direction, it helps the bike balance better. If you don't believe me look at this

My homemade skateboard uses the same principle.

shorter than my tadpole recumbents , they use almost 3 standard chains joined together .

guide pulleys with a chain retainer over the top ,
The advantage of using a multi chainwheel system is the front mech doubles as a chain guide

What kind of tadpole do you have? mine uses two standard chains and you have to take some links off.

Brilliant. I admire people with these fabrication skills. I'm brilliant with a spanner and will do any job on a car without compunction, but the art of welding always eluded me. Just couldn't dig it.

Looks good Bob.
The reversed fork concept clever. The way to visualize this is to consider an offset castor, say on your furniture. Push the furniture the castor will always be in a trailing position.
