Thanks Roy! That was much easier than I expected....

Here's how I tackled it.
Took off the sticky label, and cleaned off the sticky stuff. It gets everywhere!

Opened up carefully. Noting the fine thread screw, top left........

The depth probe is held on by a whisker, only........

Removed anything which didn't look like a DRO, and re assembled.......

Two existing M4 tapped holes, took a 40mm wide piece of filing cabinet.
Add a couple of magnets, and it looks/ works ok.........

Another Round Tuit, finally sorted, and put to bed........
