Just supposing it were possible ;)
If I wanted to fit an auto-tool-changer to my mini mill, what would be used for the spindle?
That seems to be the only stumbling block really, the rest is just building and macro stuff. There seem to be a few variations - carousel, straight bank etc but all need a spindle that can be released automatically.
Are ATC's for the rich boys only??

OR for those that can justify £1500 for automation because it will pay for itself! Few on Aliexpress starting around $2000

Bum, would have gone £5-600 just for the luxury but that's just too much ;)

Haven't seen any cheap DIY worth looking into I think this is about closest but not for me.

The spindle is the hard part.
Quite a few people use the Tormach system (TTS), which I think is essentially a modified R8 spindle/collet setup.
You could go for a conventional ISO/BT spindle with a drawbar, and attach an airgun for loosening/tightening the drawbar.
Best option is some form of ISO/BT gripper spindle, but they are expensive. I'm sure I've seen ISO30 ATC spindles for around £800, however you need to add a motor to that.
I still have a DaleCNC ISO15 spindle cartridge sat in the workshop doing nothing if you're interested. It cost me about $1200, but I'm open to sensible offers as I've currently got no plans to use it on anything.Avoiding the rubbish customer service from AluminiumWarehouse since July '13.

its not too bad at the low speed end but my spindle is a 24,000rpm water cooled job, my machine was built for aluminium really so it needs the speed. Looking at £1600-£2300 on Aliexpress :(
