I made a grinding rest for my bench grinder,a somewhat different design,because I tend to use the side of the wheel rather than the front [which has more hops in it than a pint of bitter ] I can tilt the rest to suit both sides of the wheel and by fitting a simple guide I can grind compound angles. I can also use the front of the wheel,if need be and also have vertical movement of the rest. It,s nothing fancy,but it works !
One of these days I must get around to making a proper rest,something that looks the part,anyway,but for now ———————-Twill do !
Not sure about the vise stop,can you explain its purpose ?
