I’m calling on the fount of collective knowledge here with a technical question. I’m refurbishing an sp-15, and as I was cleaning up the underside of the cylinder carriage I noticed that a rocking lever arm (what is I assume part of the trip mechanism) was sprung with a flat spring on one side – the operator side – but not on the other side. Closer inspection revealed that the spring on the far side had snapped off at some point. My question is – it appears a very complicated operation to replace the spring, is it essential for the press operation?
with thanks and best wishes
