I use a larger diameter spring that fits over the boss on the pressure plate. Being larger in diameter it has a lower spring rate and is less sensitive to adjust.

The outer end has a stepped "washer" that locates on the thread and inside the spring. Mine is brass but it could be aluminium. I have also thought about threading the "washer" and making it a larger dia, so that I could just have a plain locknut to hold it in place. That way, when it gets hot it doesn't soften the nyloc; which results in the slipper setting backing off, making it slip even more and then get even hotter!!!!


PS If you are going to over-stress the spring by taking it to a point where it is coil bound, please wear safety goggles. If it escapes from the jaws of the pliers it will be travelling a quite a rate!
