If you are here you probably already know what IndyMill is! If not check out this video:
The steel plates kit is composed of 11 custom-cut steel plates. Z-axis rail supports are 8mm thick and everything else is 6mm thick. All parts are powder coated with RAL5015 and tapped.
I decided to tap those parts on my own even though it takes a lot of time. It’s quite easy to break the tap and destroy the plate that way (broken taps are really hard to remove). That way you also get ready to assemble kit that you can easily use to build your IndyMill!
