Hi Andy,
In your opening post, you say: ' I’ll have loads of questions to ask about the mill '.
If the digital version of the MEW magazine works, I would strongly suggest that you subscribe to it.
Once subscribed, you can look at the back issues of the magazine, starting from issue MEW 261.
Issue 261 starts off a 'Milling for beginners' series based on the SX2.7, written by Jason, who is one of the moderators on this forum.
The series continues in alternate issues of the magazine, 15 parts, which ends in issue 289. Jason has a thread on the forum based on the series. See link .
In the absence of a 'hands on' coarse, I would suggest that most of the questions you have about the mill, along withe the associated tooling will probably be answered in the series.
