Final solution for my Yam rear brake

yves norton seeley · Jan 17, 2017

What I did before:
Welding two SS gusset on the swingarm to fit the anchor bar, but a friend, who is a top welder in the nuclear industrie says: don't trust the welding, stainless steel and Reynolds 531 tube don't match for welding, soon or late you will have problems!
So I cut the two gusset and I make the drawing from what you see on the pics now.
Starting from one bloc of billet aluminium and 8 hours of milling we have the result.
OK, I know, it looks as comming from the ware house of a Panzer Divizion, but I prefer to have it strong, I don't wish to finis in the Emergensy Division
Stiil not tested, to mutch salt on the roads.
Tomorow the Seeley is going to the Tank Shop here in Belgium for a new thank, and this tank will be amazing
Keep you posted

Full floating backing plate. Beautiful work Yves.

Fully floating should be attached to the chassis not the swing arm, but this is very well executed and looks great.

Just to clarify the two comments above Yves torque arm was originally connected to the frame but was with out a floating brake plate,he then welded a lug for the torque arm on to the swing arm but with the possibility of the weld breaking he removed it and made the clamp on lug that you now see

+1 .....beautiful work for sure Yves. Just out of curiosity though, couldn't the gussets have been made out of something other than SS, so that there would be no dissimilar metal issues with the weld at the swing Arm?

531 frames are typically bronze welded, which is the best solution so as to not add stress to the frame parts from the welding process itself. So there is more to it I think than just the dissimilar metals.

There is nothing floating on the whole system, the backing plate is clamped between the two arms of the swinging arm and the piece of aluminium is also clamped

yes of course, normal steel will do the job, but after welding you have to re-chrome the swinging arm and I don't wish to do that at the moment, I must save some money for my new gas thank

You right, but I don't wish to use a acetylene torch wih the engine in the frame, to dangerous for fire

Yes, my error, nothing floating about it; I was fooled by the Heim joints, and yes, it would have to be attached to the chassis, not the swing arm, to float. It is still beautiful though.
