Having been constantly frustrated by the rotor jumping just as you get the timing marks aligned after setting the points, I was thinking of making up some form of stopper mounted to the frame for the spanner to rest at the correct mark.
Various contraptions were tried and binned. So the scissor jack system came to light. The jack is roughly set at a height so that when the vice grips are turned towards the timing mark the lower end of the grips rests on the jack.
Provided the grips are holding the rotor just before the timing mark the jack can be wound down with almost vernier accuracy to the timing mark. Then timing up is easy without the rotor wanting to jump
