Usually, you’re right. But having the actual machine is only half the problem.

Last place I was at we had this big beautiful ride along mill that was just magnificent. Between the attachments and tooling we had, it was capable of producing any part of itself down to the last nuts and bolts. With the right know how and materials, it was capable of self replication.

We torched it for scrap. Not me, as a dumb dumb welder, but the business. There was nobody we could find with any combination of a) space to put it, b) ability to pay for it, and c) know how to run it. Best we ever managed was two of the three, and since there was no money in it for the business, they elected to cut it down for scrap value. Got one of the best t-tables I’ve ever had to weld on out of the deal, but it was still a travesty.

So yes, while the machines work fine, it’s hard to find people with the skills to run them effectively, the space to actually house the machine, and the spare cash required buy and maintain it.
