This is still an unsolved question in OSE project and deciding for one of these options will have consequences for the outcome of the GVCS and the complete OSE idea.
1. Going for bootstrapping from scratch makes for a very long lasting process, and the final result will be open in useability and quality. Maybe a very few people will be able to produce their shop tools with acceptable quality, but this requires time, patience and especially high technical skills. Because of the lack of skills most people will produce shop tools with poor performance and quality.
This will influence the design and quality of the GVCS machines built. OSE specifications call for high performance and industrial efficiency, but with the poor tools homebuilt these goals are out of reach. GVCS machines under this strategy will be poor built low performing machines without any operator comfort.
Gingery books are interesting, but there are 2 drawbacks. I have never heard of someone who did some precision measurements on his machines to compare them with industry standards for machine tools ie lathes, mills.I doubt if they meet these standards. Another issue is these machines are pretty small. Too small for many of the GVCS designs. And it would be much more difficult to do a homebuilt of these machines with double or trifold sizes.
2. Making the GVCS a real replacement for industrial built machines requires higher capabilities, skills and shops with equipment of sufficient performance , precision and quality. With these conditions met, there's hope for GVCS machines being really of high performance and industrial efficiency.
For the short-run, the "cheaper open source machine shop" will just be a dream. OSE is still far away from designing quality machine shop tools. As long as they are talking about a CNC multimachine, I don't take FeFs attempts to build machine tools serious. Most multimachine tools perform poor, a the few ones that are fair performers are highly complicated machines. Not suited to DIY !
Conclusion: Either we build the shops from scratch or we have to rely on industrial built tools for the next couple of years.
Building from scratch will slow down the spreading of GVCS and GVCS machines will be cheap low-quality. They may be of some value still for poor countries where people for example find it a big progress to have a tractor, even if it has low perfomance, breakes often (but simply to repair) and has low standards of safety and operator comfort. In the industrial world such a GVCS won't be a success story, I am sure about that.
So to make GVCS successful in the industrialized world, it must be competive with commercial products, not only cheaper but poor. This calls for the shop from market. Even if OSE once has developed quality shop tools, someone without a shop will have to buy them first - without machine shop You don't produce good machines !

I suppose we'd have to put a number on "acceptable" quality.
It would be interesting to figure out how much of the bootstrapping process could be pre-defined vs how much of it would require a knowledgable operator to be there at the right time.
Maybe the bootstrapping process could be empowered by a cheap internet connection. When you get to a spot where you don't personally have the knowledge required to be successful, you log on and get help from an expert. That way the experts would maximize their time by only "showing up" when they're needed, and they would be able to impart most of the relevant knowledge by teaching the operator how to get past that step.
"...he must have the comfort of knowing that whenever a component breaks, he can buy that component from OSE (or from others) at the decent price for it, and he won't have to buy another CEB Press. Only the commitment of the OSE community to supply the parts to the people who need it, only the availability of components will change the world."
> The way I understand it, OSE machines are built out of stock materials with as few machining steps as possible. That means the vast majority of the components are commodities that already have robust, competitive markets. For example, the optional control circuitry for the CEB press uses components you can walk into Radio Shack and buy, or order online for pennies. That way OSE doesn't have to become a supplier.
"...just to make sure others won't be tempted to play dirty (not supplying parts or selling them too expensive)."
> The idea is to keep the machines so simple suppliers will always compete with each other on price. When that's not possible, make the specifications freely available so that anyone with the right tools can become a supplier.
"When OSE will supply the machines AND THE PARTS, at decent price - and will stay committed to it - then the poor people will finally have the opportunity to buy them and to repair them."\
> You mean like a charity? Do you mean give the machines away for no or next-to-no cost? I don't think that's OSE's charter. Also, there is no need for OSE to take on that function. All the information necessary to make the machines is freely available and OSE will provide training if required. So, if someone wants to start a charity to donate machines, they have no barriers to entry. All they have to do is start making the machines.
"Clothes are not basic things? Machines that make and wash clothes are somewhat ridiculous or what? What's wrong with them?"
> We've been around on this subject before. The GVCS can make appliances. Appliances cannot make the GVCS. Things that can make things are more necessary than labor-saving devices. Appliances will be made AFTER things like machine shops, houses, and plumbing. Or not. There's nothing stopping you from starting an open source appliance project.
"The availability (supplying parts) is the key to change the world."
> Agreed. That's why the infrastructure that turns raw materials into parts is more important than the parts themselves.
"...the project should start with making at least 3-5 of the most desired and easy to make machines: Home appliances. That will help generate a lot of sales"
> OSE isn't a for-profit organization.
I think the key to answering the OP's question is to determine what open source design can create the most value for DIY'ers per hour invested. I haven't done any calculations, but my intuition says tools for growing food and building housing would be very effective. Thus the Lifetrac and CEB press.
Once the concept is proven, it would be great to open source the entire economy. However, we have to start somewhere.
"I thought the specifications will be freely anyway, not only in case that the supplies don't compete each other on price."
> It would be clearer if I rephrased that as, "keep non-stock parts simple enough that they can be produced on machines and by people who are part of robust, competitive markets."
"when nobody wants to create parts, then the OSE should make them (for a profit, but at decent price"
> If OSE can turn a profit making them then why wouldn't someone else do it?
"It's common sense to assume that by saying that, OSE means it will take care that the people can buy the parts they need."
> No it's not. OSE is merely promising to do the science and engieering to produce functional designs. No additional relationship is stated or implied.
"Because forcing the farmer to buy another 10 machines just to make parts for his OSE tractor isn't exactly "cheap" for him."
> The cheapness comes from the increase in options. Just like a machinist isn't going to harvest grain, a farmer isn't going to make splined shafting. OSE is working on open sourcing a complex and integrated system of infrastructure, OSE is not working on eliminating the concept of specialization of labor. You don't build a village out of one farmer. The guy who owns the machine shop down the street makes the parts for the farmer who makes the food. I didn't think it was that hard to understand.
"Can you imagine a naked self-sufficient community?"
> Yeah...actually I can. Humans were self-sufficient and naked for most of their history. There's no mechanical reason why clothes are necessary to operate digital watches. We could go back to being naked if the culture wanted to.
"Why to refuse to make more money?"
> Because it would replace the work OSE has already promised its supporters it would do. If it's such a great idea, why are you refusing to make money with it?
"Clothes are not basic things? Machines that make and wash clothes are somewhat ridiculous or what? What's wrong with them?"

One problem is, the GVCS50 is a mixture of machines. Without following one approach consequently.
There are things for consumer items. And there are investment items. And there are machines to produce machines. Thats 3 different categories. But all are mixed up in the GVCS50.
A CEB press doesn't produce machines. But it produces investment items, ok, has to be qestioned if you build a house. But if You build a factory with those bricks, its an productive investment. From the GVCS 50, there are many machines that don't produce other machines. Tractors, bulldozers, trucks, though these are productive items. Therefore its wrong to say the GVCS contains goods that produce machines, that's only true for more or less a dozen of the GVCS50. Okay, maybe two dozen if I count machines that produce raw materials for machines (steel roller, aluminium extractor...)
Also there are a few items for consumers in the GVCS. The bakery oven doesn't produce anything productive, "just" bread and pizza. The car is more a consumer item than a productive item as most cars today are for personal use. I don't think we should integrate a washing machine in the GVCS, but to be consequent, the bakery oven has to be removed from the GVCS set too as it not a bit more productive than a washing machine.

For the short-run, the "cheaper open source machine shop" will just be a dream.
That's totally false. The open source machines are much cheaper as you can replace parts at dirt cheap.
>
Well, currently there are no 'open source machine tools' available. And, according to all information in the forums and the wiki, there will be none in the next years, that are competitive to commcial machine tools in performance and quality of work.
'Simpler'? A simpler machine means most often a machine with lower overall value. Industrial research has over years explored most ways to reduce production costs of machines. And its a myth You can produce a machine with comparable value much simpler. To ensure same quality, You need the same quality and materials and the same precision in manufacturing. This is valid as long as OSE specifications call for "high performance", "industrial efficiency" and 'livelong quality". If we give up these standards, OSE machines will be simpler and cheaper. But IMO than it has become a third-world GVCS.

I suppose we'd have to put a number on "acceptable" quality.
It might be difficult to rate every feature of a tool with a number. But there are aspects where "numbers" are known for decades in mechanical engineering. Numbers for power, precision, stiffness, positional errors for CNCs.
There are a lot of books that give data for required precision of common machine parts. And there are a lot of printed standards from ISO, DIN, GOST and others for required precision of machine tools like drills, lathes, mills, grinders, planers. These are minimum requirements, machines from good manufacturers with reputation usually have much lower errors. But I would agree that a machine that meets just the standards is "acceptable". A really good machine has to be better, also because machines become less precise through wear over time.
Machine tools with significantly less precision than given in the standards aren't acceptable - it's simple, Matt !
There's a tendency by many supporters of OSE to say, we don't need precision, its OSE, it should be simple. Thats a dead road.
The datas for precision in the literature and from component manufacturers are based on experience from 2 centuries mechanical engineering. Regarding them as a joke is ignorance, but its often found among people who deal with OSE projects. Sadly its also found at FeF.
Take a ball bearing as example. Its no secret how to design the shaft and bearing for, You'll find it everywhere, permissible tolerances included.
And a ball bearing doesn't care that it's part of an OSE machine. It demands its proper "living conditions". Or else it will work poor, create noise and quit its service soon. Thats the truth about keeping it "simple", where simple in OSE designs means we do it primitive and coarse. Thats what the term simple really stands for in OSE.

Sorry, I can't give You links to good literature in English.
Lifetrac, well, my last information by MikeA is that FeF doesn't use the Lifetracs anymore. They are developing a Lifecat skid-steer loader roughly based on the Lifetrac.
Maybe some people at FeF have realized that the Lifetrac design doesn't have the potential to become a good agricultural tractor.
Obviously, Marcin favores now outsourcing the development of machines to commercial companies, so I wouldn't be surprised if a new tractor design is developed by a commercial machine shop.
Personally, I am not sure whether we should be happy or sad about this outsourcing policy ???
:-S
Mike
"Can you imagine a naked self-sufficient community?"
>:-((
Therefore I don't think FeF should start a worldwide spare express service, spares should and will be produced by the manufacturers of that specific machine type. Only if FeF itself sells a machine, its their duty to deliver needed parts. Not because its an OSE machine, but because it is FeFs client.
Mike
@Matt_Maier
You are simplifying the task of producing of producing machine parts, Matt
To be able to produce most parts, You need an assortment of different machines, most of them aren't in the GVCS set. Besides this, there is also a size problem in manufacturing. You can't machine parts that are larger than Your machines work area. You can produce parts that are smaller, but even this has limitations. Tiny parts on very large machine tools also don't work.
Every machine shop will be able to produce spare parts for a washing machine, but not every shop has large enough tools for all parts of a tractor,truck, bulldozer. I have seen a lot of shops and there were some, not shops but real large machine factories with hundreds of workers and machines, but You won't find a mill large enough for eg. a truck engine block
=((
Even if OSE publish designs for large machine tools, most shops won't build one. Large machines need a lot of shop space and building them consumes a thousand or more man hours.And You have to buy the raw material. A 30 ton milling machine consist of 29.9 tons of steel and iron - just the material will account for more or less 100,000 bucks. So no shop buys or builds a large one except they continously need one.
Local shops won't be competive in price, too. For them these items are single builts and they need a lot of time to make them. A manufacturer in a market with competition can produce them cheaper because he produces them in larger production runs.

"When the people using OSE machines will be successful, then the OSE project will surely be successful."
> Success is in the eye of the beholder. A cutting edge, brand new, paradigm shattering technology project has unusual metrics for judging success. I will say OSE is successful when it inspires and supports businesses to provide and support the GVCS. I don't think it makes sense for OSE to take on the role of a business.
