The rails and screws that came on these machines are amazingly accurate (for what it is), but the open-back column is a noodle.

And I suspect the base where the column mounts may also be flexing a bit locally where the bolt holes are. We'll see once I fill it up and box it in.
Can you give me as much info as you can about your BT30 spindle upgrade and PDB please? I've been cutting a lot lately and my R8 spindle get blazing hot now, like too hot to touch for more than a second or so. When I turn it by hand it's starting to feel rough. Probably going to have to replace that too soon.

Thanks!
