I've been very busy about the project. I've made a couple more drawings and made all major decisions regarding dimensions, geometry and material. Mild steel tubing through out it will be.
I've also finally made up my mind about building some sort of jig. I got a lot of inspiration from many home builders who post their acomplishments everywhere on the net, plus one very informative article on jigs for motorcycle frames. My jig has a little from all. Let's see if it can really do some good to the alignement of my coming Bakfiets.
I've been reading, learning and practising lots of stuff on metal working. Mostly from Atomic Zombie (tutorials, blog and forum). Incredibly rich source of highly usefull info. Frame chopping for parts recycling, tubing preparation (fish mouth cutting and the like). I even bought some plans for future projects.

Tube notching can get a lot easier with this (among ohters) online software for calculating and printing a paper template for cutting fish mouth in every conceivable diameter/angle/off set combination. Great stuff.

I'll up load pictures whenever I have time - for that.
