The donor bikes were KP-18's, junior versions of the venerable 'Kingpin'.
These came from recent purchase of a stash of 7 'cycles, 4 of which are Raleigh 'Twenties', the pick of the crop is a 'mint' 1978 'Shopper', which is the one I was after but the vendor wouldn't split the bundle. The other 'Twenties' are BSA and Triumph versions.
The fourth one is a later U-framed version.
Not one folder among them.
Instant collector LOL.
The towing 'cycle is connected via the black end, the round thing at the at the other end is of course the rear.
Still waiting for some hemi joints which will be attached to the 'cycle drop outs, in turn attached via the pneumatic fittings to the forward ends of the prongs of the black member, and provide a quick release of the entire thing.
That will give vertical pivot for the whole shebang.
The b/b joint allows horizontal movement,
The 'spine' is waiting for 2 cross members which will have the bottom of a plastic bread basket as a bed for the 'box' element fitted to and finishing assembly.
These first detail allow me to assess the levels, from which progress can continue.
I've walked it around the garden and it does work.
Additional length is about 2/3rds of the cycle its self.
I'm delighted to say, I'm on target with 'PLAN A'
Thanks for your interest.
