Model number five in my series of free machine shop instructions is this big cylindrical grinder. It has a movable guard and posable indicator arm. There’s just one fiddly steering wheel to prise apart on this one, plus two of the larger wheels.
This was actually the third model I designed but it was stuck at the back of my engine shed and I nearly forgot about it! As always, there’s a gallery of images below or you can download a full PDF and parts list.
