After some discussion with the customer, i decided to try building something using more existing bits and pieces... engine made up from whipper snipper motors and then trying to find some wheels to suit.
Motor came together failry well though not really in prportion. To hide the whipper snipper crankcase I had to fabricate an oversize gear case and heads and barrels size was determined by the whipper snipper barrels. Engine is 190mm high (length of wrist to 'Hawaian happy sign' finger).

Wheels proved to be a major sticking point and as you weill see from the pic, the rear wheel is a bit large and certainly has excess rubber. It could be improved by replacing solid hub with spokes and hub made in the workshop... too time consuming at this stage. Front wheel remained a problem until this morning and I finally made a hub and welded it to a broken pram wheel. About right size and not too bad once the tyre is painted black!
I have done as much of the shiny stuff in stainless or aluminium so the customer can polish his heart out!
All shiny bits and engine unbolt to make painting and polishing easy.
All welding is with the DHC either aluminium welding (still getting the hang of it) brazing or stainless fusion welding.
Left to do now is seat and tank which I will carve out of timber and double headlights for which I have a couple of bicycle bells to give rear curve. Unfortunatley they don't match, but I will put up the sizes I have in the hope someone has one they would like to donate...
Model is 930mm long. Springer works by the way...

On the assembled model you may see that the airlcleaner is no longer a cyclops wheel hub but a Harley petrol cap. It has a whipper snipper carby behind it for effect.

Oil tank is stainless tube with a piece of 2mm plate cut out. Battery box is part of rectangular stainless tube. Pipes are solid half inch stainless round bar so the bends wouldn't flatten or kink with half inch stainless tube for the straight tail pipes. Top pipe is welded to pillion foot rest which is internally threaded and bolted through the frame.

Classic 70's chop... long and lean...


Gearbox is unfortunatelly a bit small for rest of bike, but doesn't look too bad. Has kicker (can you spot the mistake), oil filler and clutch arm

As it has turned out, the bike is still well over expected price, but this being a bit of a special case I'll wear the difference.
