Naturally, blades joined in this manner won't worn on NWWM :-) The JK Woodcraft jig shown is a prototype from 1987. The newer ones are galvanized and don't rust up as easily.
How you grind the scarf joint is up to your using what faculties you have. I like this rig better than any other I've tried because it keeps that thorny snake of a bandsaw blade off my shoulders and more at my feet.
Not shown is what to do if there's ticking as the blade runs through the guides from a high spot. Color the blade with a felt tipped marker, roll the blade through a few revolutions, observe where the color has worn away and get out the dremel and grind down those spots.
