I have a "Performance" brand compound mitre saw from B&Q.
Label is missing so no model number. I need a new LEFT HAND CUT helical spindle gear with 32 teeth. Outside diameter of 43mm. Inner hole diameter of 12mm with a 4mm keyway slot in the inner hole. Total thickness of 12mm. I have searched EVERYWHERE with no luck.
WHY IS THERE NO CATEGORY FOR MITRE SAWS??

You could try Solent Tools (search) but I doubt the pile 'em high and sell 'em cheap stuff has any significant support, if anything. B&Q might be able to help but I doubt it.
