February 1, 200818 yr Was also trying to find a solution for damaged bottom frame tubes on my (soon to be renovated) '82 Mont 200. I remember back in the '70's, Rob Edwards did a cut frame tubes out and install Aluminum bash plate on my Mont 247, it looked and worked a treat. Does anyone know of a suitable AL bash plate that could be used (with some plate welding) for a Mont 200 ? Sorry this isnt a solution for you 125 Gold, but some of the answers or suggestions may be similarly useful ! Cheers,
February 2, 200818 yr 7075 T-6 alloy is the stuff, about .186(3/16) thick! You cannot really form this stuff in it's hardened state, the formed ones are heat treated after forming. U cannot weld it either! You may be able to do some cold forming on it with a proper press setup, but the bend radius is very limited. To get the strength out of a more forgiving alloy like 6061, you would need to go to at least .250 thick ! Even though it is much more flexable and weldable, you better be set up to do it!

February 2, 200818 yr I have made a new plate for my 4rt, 6mm thick but can't remember what spec. Will have a look when I get back to work on Monday or have a chat to a local metal supplier in Yellow pages or see what some of the after market suppliers are specifying. (if in doubt copy) Approx

February 7, 200818 yr I have used 5052 in 3/16" and 1/4" thickness. From McMastercarr Forming and Working Also known as workability or bendability. It's the extent to which a material won't crack when bent without applying heat. Excellent 1100 Good 3003, 5005, 5052, 5086, 6063 Fair 2011, 2017, 2024, 6060, 6061 Poor 2007, 852.0, 4032, 6013, 6020, 7068, 7075, MIC 6, QC-10
