Robert.
Pleased to see my post may be of help.
Regarding, bypassing the existing stop/start switch. As I don’t know the type of start/stop control fitted to your saw, I am unable to give you exact advice on any wiring modification, but if it is a standard type of start/stop, NVR (no volt release) control, just linking across the start button/switch would be all that is necessary.
However it is important that whatever modification you carry out, is to label or cover the start/stop control, as inoperative, I appreciate you may be the only one using the saw, but on the off chance that an -other was to use the saw , they would need to know that the STOP button is not going to work, (ie stop the saw). :shock:
Or as Martin said, you could remove the NVR control and go stright into the motor supply lead. If you do this and the foot switch is only single pole, ensure that the switch is breaking the live wire, if the foot switch is however two pole, no need to be concerned.
Glad to see you enjoyed your holidays in Cornwall.
Take care.
