[/url][/quote]I'm in the process of doing 12 of these, much smaller than yours, for Locomotion, by similar methods. Yours is much better finished than mine are, at present anyway. I've had to resort to hand stamping the parts of each assembly, because each one is individually fitted. The slot that is 1 3/4" long on yours is only 3/4" long on mine.
The first one was interesting, but I admit that 12 is becoming tedious.
Just to show that I'm not entirely of the Fred Flintstone generation, if I'd had access to EDM equipment I'd have happily used it for the slots, rather than drill, mill, slot the ends square and finish file

The slotted holes are the biggest part. I toyed with ways of fabricating metal around the hole which I didn't end up doing. Cut from solid. However that may still be an option for a smaller joint? Silver solder two parts together leaving the hole open? 12 off sounds quite daunting but rest assured they tighten up really well.[/quote]
I'd never thought of fabrication, but it doesn't really appeal somehow. Anyway, I've already slotted the U shaped component, and am about to slot the rod end. I haved made a couple in the past, and yes, they do tighten up well. Some full size ones I've seen have a set screw through one side of the rod end, bearing on the cotter, which is supposed to discourage the cotter from slipping out, but that isn't on the full size Locomotion, so I'll probably settle for drilling the cotter and fitting a 1/32" split pin.
