They are good. They are made in the USA (in Arizona) and come completely equipped with CNC controls and software that will work on any Windows computer. Ball screws, a rotary 4th axis, and a high-torque variable speed spindle motor are available options, as well as an extended Y axis for wider...

If that's the goal, he should look into MOI (Moment of Inspiration). It's a native 3D program that manages to be both simple to use and learn while giving users the ability to create forms based on complex curves (NURBS), not just straight lines. It was written by the original author of...

I'm of the opinion that if it's truly a better product, its beauty will shine forth. I'm not talking about superficial surface treatments, but the object - or theorem or theory's inner logic showing itself for what it is. "Beauty is truth, truth beauty,"--that is all Ye know on earth, and all...

I second the recommendation for the Taig CNC mills. You'd be better off with one of them if metals are what you're mainly wanting to cut. They've got plenty of room in Z (Scott's points are well-taken), and have recently introduced an extended Y option that makes the working space wider. (See...

Greentwin - thanks so much for all this information! It makes iron casting at home seem a lot more feasible than I'd thought. A few questions: Does the ferrosilicon lower the melting point of the iron to make crucible-melting more feasible? Does it change the working qualities of the metal in...

I'm enjoying this thread, and appreciate all the links to informative videos. But without actually watching all of them, it's hard to tell what exactly you all are doing in order to cast good iron engine parts in your back yards. Can you summarize the process for us? I gather this involves...
