there are forums and sites dedicates just to this topic.
I was just about to make one but i change my priority list.

There are open source blueprints in CAD - but usually u need another cnc to make it.

It is not that difficult.

Default Google CNC Kits....

...and this one came up

This is "talking outta my butt" territory but, is MDF ridgid enough to make repeatable, accurate cuts? It looks pretty well braced though. I guess my prejudices are showing here.

I guess as long as it is braced properly it would do for a while.

I dunno. It's a big project, and you should already have a shop if you're serious about it. IMO, if your time is worth a nickel an hour, you should just go and buy one of the various mini-CNC machines that are sprouting up all over. I'd have a look at the Tormach (Google is your friend) because it looks like a serious machine you could do a lot with for way under $10k. The very similar Smithy is also worth a look. If you just stick to smaller parts, you can outfit the Sherline machines with NC control. Ten years ago I thought about a diy NC, but it makes a lot less sense today.

Exactly my idea.
The Tormach you mentioned looks like a nice mill if you need to work with steel. Would be great for making field coil drivers

For working with wood, brass, aluminum and such the CNC-Step looks very attractive (starting at 2250 euros).
