I can't get the DHL site to work for me, but UPS charges were (gulp) ~$440-$530.
I have a theory called, "The Tree Fort Syndrome" in which a group of little neighborhood boys decide to build a tree fort together. There is lots of excitement and chatter as they gather materials and plan for construction, but after a few days interest is lost. In the end there is no tree fort and one unfortunate father is left to pull nails out of a tree trunk in his back yard, clean up scraps of lumber and search for tools left strewn about and rusting in the morning dew. Meanwhile, the boys gather at another father's house and excitedly plan to build a go-kart...
I don't mean to sound discouraging, but there are lots of M42 stroker "tree fort" stories on the internet. By "recipe" what I really meant was a stoker build thread that was actually completed and running without an inordinate amount of expense and exotic fuel/engine management.
