The Ultimate Indian Motocycle Hybrid, the marriage of a vintage Scout frame with a Chief engine!
The Alchemist
The essence of motocycle, picture a rigid framed vintage roadracer, leaf sprung fork, single pan saddle, hand gearchange, foot clutch, left hand throttle and the biggest production Indian engine of the time shoehorned into the best handling Indian frame of All time! A true hotrod, the looks of a stripped down wall bike on steroids!

Progress
A bit of time in the engine room on the lathe today and the cross brace is ready to be welded in place
With the right gusset I beleive it is possible to make the frame twice as strong if you would accept a tank in two parts. I have used this method in two (not Mc)projects and was surprised of the results and made the cages much stronger and lighter. http://autospeed.com/cms/title_Zero-Cost-Modelling-of-SpaceFrames/A_111095/article.html
Thanks for the link Charlie, I will be using a two piece tank, repop junior scout ones. I will be adding a drilled flat plate gusset running through a central slot milled into the crosstube, this will pick up the head steady bar between the cylinders and run up to meet the curved top tube of the frame it will stop the crossbar/bridge trying to twist around the bolted fixings and add triangulated strength to the whole front frame. the flat bar will be welded in position to the crossbar and bolted to a tab which will be welded to the top tube so that the whole crossbar assembly can be removed when access to the cylinders is needed. Today I made up revised plugs that fit into the cut back frame ends, the new ones are counterbored to save weight and the outer diameter is the same 1.125" as the original crossbar so that once the tanks are in place the crossbar looks like a standard 101 frame.
