Hi All,
A while ago I picked up a Porter Cable Circular Saw, Model 447 Type 2. The blade bolt was broken off and the previous owner had tried to chase it with a drill, which broke also. I got it removed, but now I'm not sure of the thread, I know M8 x 1.25 & 5/16"-18 are very very similar threads, and both seem to engage for a few threads, but I don't want to ruin taps by trying the wrong one. Does anyone have a similar or the same saw that they can check the blade bolt thread for me?
Thanks, Ivan
