Gazzar Posted June 19, 2015 Share Posted June 19, 2015 Well, it looks like this is within the reach of a serious hobby fixer, after all! If you get a steel spot welder and sandwich the alu panels with steel strips a basic steel spot welder will do the job. Youtube it. G.

JeffR Posted June 19, 2015 Share Posted June 19, 2015 Here's a linky: now tha's a clever and potentially useful little trick, all I need is a spot welder.... Quote Link to comment Share on other sites More sharing options...
De Ranged Posted June 20, 2015 Share Posted June 20, 2015 Now that is something I'm going to have to play with..... I've always done tig spot welds by drill one sheet with around a 3.5mm hole then tig weld a spot, catch is for what they are the pre-flow and post-flow on the argon is huge Quote Link to comment Share on other sites More sharing options...
missingsid Posted June 20, 2015 Share Posted June 20, 2015 It would be very interesting to hear if this will work with LR alloy as this is going to help restorers? Quote Link to comment Share on other sites More sharing options...
De Ranged Posted June 20, 2015 Share Posted June 20, 2015 I'll have a go at when I get to the body I've got plans for a few extra pannels to tie to the outer skins on the front guards and replace the rear sides This is still 6 months off at the speed i'm moving (and I'll have to modify a welder to increase the reach...)

maxandgrinch Posted June 25, 2015 Share Posted June 25, 2015 It would be very interesting to hear if this will work with LR alloy as this is going to help restorers? I've used that technique on both vintage LR brimabright and whatever the modern LR alloy is. I use a standard light duty 2.5kVA Miller unit and would probably work with a 1.5kVA model, by increasing the time. Couple of tricks: try it on scraps first, so you don't end up with holes or ultra brittle points which will break at the first bit of stress. A small drop of clean oil on the spot welder tips will reduce the amount the insulators stick to the tongs/prongs of the spot welder. Try stainless steel between the tongs/prongs and the brimabright. Don't forget to document the settings for next time. Quote Link to comment Share on other sites More sharing options...
