More progress on the Gemini. I tried using pipe clamps for hinges that would snap over the front bar/lifting handle but felt they wouldn’t be strong enough so removed them. I came up with an idea that would enable me to lift the barrow attachment onto the bar but remain secure whilst carrying a load. I cut a section out of a pair of eyebolts, just enough to allow them to slip over the bar, and fixed them to a length of steel angle, which also provides some support and rigidity to the bucket.
i then used some steel angle bolted to the rear lower edge of the bucket and cut a slot down one side to engage with the bottom of the tipping lever. It looks a bit rough and ready at the moment but it does work really well. Some more tidying up later before painting.
