I agree about the personal satisfaction in making one’s own tooling, and even better, using it. As a bonus, because it was for personal use, its often been made more accurately by far than some of the professional stuff. (In our circumstances wear and tear is not a major problem)
So I made all sorts of dividing heads, a complete mill, boring heads, vices, mods to the lathe, rotary tables, interchangeable mandrel sets and more yet which was indispensable (on the day!).
The problem comes when a visitor comes and looks at this well appointed workshop, and says “When are you going to make something then?”
So tooling has a fascination all of its own, but it gets you left out in the cold.
A Stuart 10 which you can knock off in 3 or 4 longish evenings and bits only have to fit where they touch and it will still go OK, has them drooling as it runs on air.
So where are the priorities?
