Wow, that quoin took me back to the days when I ran a letter press. Nice job on setting up the part for machining the features. I eagerly wait on the other videos so I can continue to live vicariously as you complete the build.
How come with all the focus on precision, they can’t make a centered slitting saw. Never have I seen one cut evenly, so they rub every time once those twenty teeth are worn down and work harden the thing we are trying to cut.
I think the challenge is with the manufactures having to make the hole with enough tolerance that users can use a variety of arbors. Thermal expansion may also come into effect since the production shops I have seen are anything but carefully temperature controlled.
I made a 'set tru' arbor for my small slitting saws. Works like the 'set tru' adjustment for lathe chucks. I first tried an expanding arbor, but it turns out the center holes on the cheap saws I had weren't well centered to start with. It is a real pain to indicate though. If I used them more often, I'd probably make a batch of them and leave the saws on them, like grinding wheel adapters for my surface grinder.

looking good, Greg.
I liked the use of the Quoins to hold the part square👍At 21:20 a HSS center drill would have helped😉
Nice video. Thanks.
Will you plz tell me all the mechanism of gear hobber
