Need some simple castings with a tensile strength near that of cast iron? Need 75 cent bearings to replace $5000 roller bearings? Need an almost free portable electric welder? All of this and much more at Yahoo Group "MultiMachine". For those of you who hate to join groups, The "links" and "files" sections are awesome! Best of all, a 70+ page "How to Build a MultiMachine" book is a totally free download." - Link.

This is super-cool, but usually such machines require great experience of machining, access to other machines and a lot of very specific scrap parts. All this makes them next to impossible to build for anyone who's not a mechanic on a day job. Still a beauty to look at.

The "links" and "files" areas appear to be "members only" indicating that I will have to sign up with yahoo to see them. Am I looking at the wrong page?

According to the article the only machining required that can't be done by the multimachine is to bore the block cylinders to the proper diameters for the overarm and bearings holding the spindle. This is a very common operation for overhauling automobile engines so wherever there are cars there will probably be someone around with a boring tool. Once you get the bearings, a chuck and a power source, with a little ingenuity pretty much everything else can be fabricated using the machine you just built.
In my part of the world I can go to just about any farmer and procure an engine block from their junk pile. You can find precision flat steel plates and bearings inside computer hard drives which might come in handy for building a small table.

hammerthumb: the page is not wrong, you have to join - this is typical for yahoo groups and I'm not sure if it is possible for a group to have files accessible to non-members. Speaking of which, it might get the group out of control if hordes of Make readers will try to join.
Regarding machining required etc.. No arguing everything you said. It's just important to understand the duality of experience and time required to build this machine. Trying to estimate the time using my machining experience.. Hmm, looks like +NaN ;) Kudos to everyone who are going to try though.
