same here on my rapidorWe used Eclipse blades in our workshop saw, it seemed to chew through anything we threw at it.
i think the rapidor takes 14 inch blades , mine are 14 tpi or 10 tpiWhat size do you need? I've got a couple of boxes of decent Starrett blades I'd be keen to rid myself of
but cheap on blades got all of mine for no more than 4 quid a blade . press on the bow when running if you want it to cut fasterCan’t remember what’s in mine but I think they’re Eclipse.
Had to do quite a lot of cuts in a length of railway track to make some book ends, timed a cut out of interest and it was around the 15minute mark.
They are slow compared ‘modern’ cutting methods.
