I missed that in the earlier post, could have helped you out with a TIG inverter if we were a bit closer, bit bulky even for the Trophy.

I'll be there if I'm in the UK, can't be sure where I'll be yet hence the reason I've been silent on the subject.

Yeah, its the Argon cyl that would be a pain to bungee on  :icon_wink:
Hope you can make it, otherwise I will have to scratch my itch to head northward, I keep feeling an urge to make an excursion across the border - never been before, well I did deliver a drum of degreaser to some place just over the border near Berwick-upon-Tweed in 1982

Given that small lugs underneath would be just to stop slipping could you not combine two of the ideas?  ie make two small lugs for the underneath but hold them in place using countersunk bolts and rivnuts in the underside of the swinging arm??  In this way the rivnut  s could be quite small so as to not compromise the swing arm strength.

Thats another Idea, thanks BB, I'm getting there

That's some lateral thinking there BB

  It's all about keeping loads away from fixings and avoiding loads putting anything under tension or shear - that way you don't have to start making complicated calculations .....
