Skankweasel went out for a little trip to Martin's shop yesterday to get a little bit of TIG action going on the rear mudguard mounts. Had these bits water jet cut, nice finish, cleaner than Laser but worth the extra? I'm not so sure.
The brackets were cut with a 10 degree angle to allow for the curve of the guard. The tabs were welded on to the bracket after being bolted to the guard, to get the angle.
The bottom mount bolts to two 3/4" long bosses welded to the frame cross member. Not a thing I'm normally down with, but this rear section has had so much abuse over the years that it's not really heresy to weld extras to it.
The top mount is the same bracketry but picks up on the standard rear guard tapped holes.
There's still the rear loop/stay to sort out, and as it's aluminium a bit of rubber mounting will help.
