cynical Posted February 1, 2008 Report Share Posted February 1, 2008 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, Quote Link to comment Share on other sites More sharing options...
copemech Posted February 2, 2008 Report Share Posted February 2, 2008 (edited) 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!

jimmyl Posted February 2, 2008 Report Share Posted February 2, 2008 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 Quote Link to comment Share on other sites More sharing options...
