Addressing the issue of the axle rocking in the drop out. As is evident from this picture of the washer side, closest to the drop out.

Looking at this, as well as with the wheel installed, its clear that I needed to tweek the drop outs into alignment. When I bought the bike I made sure that the drop out was 135mm as required.
But my 7 speed freewheel widened the manditory space, spreading out the seat and chain stays. There by causing the drop outs to get out of alignment. Corrected the alignment, and a bit of twist on one side. Also spread the stays out to meet the needed room without having to fight it. Much better!
Was using just one universal torque arm on the non-freewheel side. Being held in place on the side of the support by a worm gear clamp.

I suspect either the play in the universal torque arm (geared insert). Play in the worm gear clamp. Or lack of lock washers in the assembly. And of course, the misalignment...
So decided to make my own torque arm. Started with cutting out from a pattern.

Finished off...

Fit...

And Installed...


Seems very tight and secure. Now to make the other side, and decide how many, and where to put the Belleville spring lock washers. Torque Specification for the axle nuts...anyone?
