It's a variation on the WW2 Parker type beading tool, there are current copies by ATS and Graham Tool. The current versions are four tools (a clamping tool and 3 bead tools), yours handles the different bead profiles by the changeable outer dies, all use the interchangeable inner dies. The new versions are around $500-$600.
Lol, I was referring to Land Rovers work as British car tolerances and yours as the Japanese tolerances, as opposed to your work improving...... hmm that sounds like a slight on you too ..... I think I should stop now
Blimey, we've moved from British car tolerances to Japanese tolerances!
Out of curiosity will the chassis flex enough to cause the steering shaft to contact the suspension mount?
Could you add an extra UJ into the mix to get you around the obstacle? You'd need another bearing mount too, but we now don't bat an eyelid when we expect you to do hours of machining off the back of a throw away comment
BTW I'm amazed how well it's turned out, I was expecting it to stretch and distort a lot, but it looks like it's only had a little stretching in the big panel.
