case of a business the customer pays for tooling anyway. If you're doing something for yourself it's
a very different scenario...

When it is for myself, I always try to figure out is it worth the
time and expense. Sometimes I get it right...

Same applies if you're running a business. I've done jobs where a nice little fixture will make it much easier.
Looked at it and said: "Yeah, we'll definitely be able to use that again." Ten years later the damn thing is still
sitting on the shelf collecting dust.

On the other hand I had a customer bring in a drawing for a part he needed; looked at it and decided: "We'll
never do this again." So we cobbled the thing together with a bunch of clamps and chunks of steel
welded to the bench--a real plumber's nightmare but it got the job done. Wouldn't you know it but the guy was
back for another one within a month. A nice solid fixture would have made the second job so easy...

:-) For me the "fun" is figuring out how to build the "Fixture" . :-)

Yeah, when I'm doing machine work I probably spend twice as much time on the lathe as on the milling machine but I generally prefer to run the mill over the lathe. Doing mill setups and fixturing is usually more challenging and interesting than just turning parts on the lathe...

Yesterday I spent many hours doing a small job for a friend. (making a hex on the end of a 3/8" socket wrench extension so it could be held in a drill chuck)
The kludge set up took hours to get it done. If I had designed and built a real fixture to hold and index it would have been a ten minute job. And a lot more "fun". Of Course if I was still able to use the high school shop like for the last 20 years it would would have been even faster. With a Spindex no "design and build" would have been necessary. I sure miss access to that shop. Curses on Covid !!!

In my experience the cheapest and easiest way to machine flats or hexes on small
shafts is to use a 5C collet block and the appropriate 5C collet. For anything up to
1" diameter this is all I've ever used--in fact, I don't even own a spin indexer...
