Right,so starting torque is over-loading it,and your fuse has saved you from real-time balance testing that blade,at max rpm x 2
I know the set up,as i spent many hours on a Lister table saw,and then converted it to a 540 tractor PTO drive...obviously,skipping the many current covenants,regarding HSE.
You will have the blade cover off? and probably even the riving knife...so,take care,fella.
Thanks!! Think it’s going to be a case of a second hand saw. Same price as a new motor!
Point taken & understood about max rpm x 2!
