If you were committed to wanting a small lathe and CNC, I’d just put linear rails on some of the larger 8020 profiles and rig a spindle from a cartridge spindle. Honestly, though, an 8x16 lathe is kinda bare minimum for steel parts unless you are working VERY slowly. The 7x14 I had worked, but at that scale, I’d be working hard to implement a clough42 ELS conversion so that threading didn’t suck so bad.
If this is genuinely something you want advice/help with, feel free to email me.
I think there is plenty of room for innovation in hobby machines, but IME, hobbiest value work envelope maybe even more than pros.
The other end of the spectrum is tools like the Langmuir bed mill/router or the avid benchtop routers with available 4 pole spindles.
There’s a lot of options, closed loop steppers are sub $100, servos from DMM or teknic are readily available and awesome.
Sherline has a product set that just felt like a compromise on everything.
In the last decade, I’ve built 3 routers, rebuilt a bed mill, converted a Bridgeport, and am currently building an automated beam saw. All the options in the market are drastically better than they were 15 years ago.
It’s sad to see a fixture of the community going out of business, but it also a reflection that the business is different now. Given the many different kits and options available, it just doesn’t make sense to buy small work envelope machines for most people.
In other words, "doneness" is the metric of quality for most of this stuff.
They have a structural advantage in cash flow and stability of funding, but stability is also a handicap when disruption is the objective.
My crepe recipe - cook on medium heat pan:
Blend on low: 4 eggs- 3/4 cup whole milk, 1/2 stick of melted butter, and 1/4cup to 1/2 cup plain flower, 1 heaped tbsp of baking powder, 1/2 tsp salt, vanilla optional and to taste
To me, AI changes the inflection points of build vs buy a bit for app platforms, but not as much for the other two. Ultimately, AI becomes a huge consumer of the data coming from impromptu databases, and becomes useful when it connects to other platforms (I think this is why there is so much excitement around n8n, but also why Salesforce bought informatica).
Maybe low-code as a category dies, but just because it is easier for LLMs to produce working code, doesn't make me any more willing to set up a runtime, environment, or other details of actually getting that code to run. I think there's still a big opportunity to make running the code nice and easy, and that opportunity gets bigger if the barriers to writing code come down.
You lay it out perfectly in your answer, and I'll add that the entire non-tech world generally feels that if tech jobs lose their shine due to AI, its actually a welcome reversion to the mean. Software has likely depressed wage growth in many other jobs.
The challenge with the example is that “success” is personal preference. With plenty of examples, the success criteria are external.
Am I wrong about this?
