So, many minutes describing non T-nut activity and apparently private CNC just mills steps? I sure didn't spend 21 minutes learning T-nut theory; scanned the time line and 30-40 seconds of video. Sorry, Casual Haze didn't win this subscriber.
Why on earth would they be milled jointly; then sawn, and drill/ tap individually? Wouldn't a tapped hole and screw be a spiffy reference stop?
A ton of jokers think CNC is the living end, be-all end all, and yet lack concepts of logical processing.

Proud handle crankers, hands up!

Pitting one against another, and even first 5 minutes here; https://www.homemadetools.net/forum/...857#post198840

CNC means can not count in my book To be sure I have had the displeasure of having to do set up on cnc machines with automatic tool changers. OH sure they are great once you have each and every tool in the changer logged into the brain of the machine and everyone of them zeroed to the ninth decimal place dry run the program through each subsequent tool change preferably doing so on a some very soft sacrificial material, then do a single part run. Inspect it nine ways from Sunday make any fine adjustments to the programing code if needed then . push the button, feed it and fan it until the batch is complete taking into account for tool wear or breakage as it does happen. In a job shop a machining center like I just described will almost never pay for itself unless the owner can come with a nitch product.
DNC is a whole different animal since it is still essentially still a manually controlled machine merely using digital readouts as a means to provide the operator with a constant visual of what is going on, and may even have mechanical stops which can be preset.
I probably wouldn't be able to anymore but back in the day I could take a Warner & Swasey "pattern" turret lathe once I had all of the tooling and stops set crank out part for part of the CNC machines of that time period of course they didn't 100,000 RPM spindle speeds either.

Agreed, CNC is still not ideal in typical job shop environments, while DNC can be. Sooner or later a 2 axis will make it out here, currently stored in CA. It's 3x as stout compared to common Bridgie's, the ram is box ways 14" wide, knee and column proportionally up-sized, a Japanese Shizuoka. She'll interpolate radii, work bolt circles, thread mill, run her linked 5C and rotab indexers, flood coolant, and save lots of repetitive X-Y cranking. Those compensate a real niche product, in less downtime and no monthly payments.....
I know a guy, almost directly south, who might need additional component production......not the incognito one farther yet south, lol.
