Spent years watching small machine shops get burned selling equipment the wrong way, so here's the breakdown:

When a shop lists a used CNC mill or lathe on a general auction platform (the big industrial liquidation sites), they're competing against a flood of unrelated inventory, paying 10-15% buyer/seller premiums, and waiting weeks for the right buyer to even see it.

Meanwhile Facebook Marketplace and Craigslist have zero vetting — you're fielding lowball offers from people who don't know what a 4th axis rotary table is worth, and there's no protection if a buyer ghosts after 'reserving' a machine.

The equipment that sells fastest and closest to fair value moves through networks of people who actually understand the gear — other machine shop owners who know a Haas VF-2 from a Fadal, who can evaluate tooling and spindle hours in one look, and who move fast because they need the machine for a job already on the books.

That's the whole thesis behind IronList — a marketplace built specifically for small manufacturers trading CNC machines, fab equipment, and shop tools with other shops who get it. No premium stacking, no anonymous lowballers, just shop owners dealing directly.

If you've got equipment sitting idle or you're hunting for a specific machine, worth checking out.
