This is my beloved Woody. By far my favourite bike to ride of all my bikes. I dont have any photos of the build so all I can do is show the finished product. The bike was constructed from a bit of 4x2 recycled hardwood and a 5 speed 20' kids bike. The vinyl I used to cover the seat cost $5 and that is the total cost of the bike.
The bike rides really well but it tought me a couple of things about frame geometry. When I ride up curbes slowly my bike tips over backwards. The center of gravity is too far back by about 100mm or so. And I would lik to be able to stretch my legs about 100mm further. I might have to invest in a CAD(http://www.instructables.com/id/Office-Chair-Bike/step1/Design-your-bike-using-a-CAD-system-Cardboard-Aid/) system.
The timber got a coat of sanding sealer and 2 coats of marine varnish.
I also added custom lightning bolts and a scull.

I feel much more comftable riding and stopping is much less scary.
The rear end I cut the original seat stays of just above the seat stay bridge and the chain stays I left about 100mm long. Measured from the dropouts. The seat stay bridge is screwed to the back of the bit of 4x2 and the triangle piece of plywood is screwed over the top.
the higher speeds, and lower center of gravity lets you brake more like a motorcycle, and less like a bicycle.(70% front, 30% rear. give or take)
Although, your design sits pretty high, so maybe a double REAR brake would be better.
Any way you look at it, more braking force is better.
With the same leg power, you'll be traveling faster.
What IS that you've used to affix the headtube into the board?
I don't see a split-and-clamp design...I'm thinking it's JB-weld?
Is the seat the same 2x4, ripped down to 1x4 dimensions? or is it scrap plywood?
