Those are good, if you have an easy access to them and you can plan them. Andrew here has some locations at the in accesible end of the panel.

Industrial Velcro. No... seriously... that stuff is insanely grippy. To the point where, usually, an attempt to disconnect two parts results in the glue giving up & the velcro still stuck together! It should be OK on a big flat metal sheet though, especially if you supplement the sticky back with some superglue or something similarly grippy. A couple of self tappers maybe...

And. . It tightens with vibration too!
They make metal velcro too. Some washing machines were assembled with it. Limited number of uses, though.

You clearly just needed special service tool part number X542984-45-92-VW
Available on special order, only £852.05
(plus tax)...
I recall an early high speed laser printer, special tools included a Philips screwdriver, only $50, plus a box of 12 toner plastic catch bottles only $120..(forget the printer model but the controller was type HP3000)

So carrying on the 'Mrs Mop' cleaning theme I decided to attack the rusty swarf guards. I've wanted to do this for a while but realising that a wire brush on an electric drill was the only realistic way, and also realising that the brushes that I had were far too coarse, I had to wait for finer ones to arrive.
Firstly I needed to remove the tools from the Baruffaldi turret. Now I hadn't expected to be able to remove the ones round the back - normally you would rotate the tool to be removed to the forward position, and unscrew it's locking rack, but I can't yet rotate the turret. However, unlike the Sauter turret on the Traub lathe on this one there is actually just room to the rear to access the hex socket with an allen key - OK tools all removed.
Then extremely gentle and careful application of a wire brush, desperately trying to avoid the lips of the wipers, followed by 220 grit silicon carbide paper with WD40 and lots of elbow grease gave quite a decent result. I'm not sure if the WD40 or my perspiration gave a better result :clap:
I might just point out that most of this activity entailed me clambering inside the lathe :bugeye: While in there I noticed that behind and above the tool turret was packed with PTFE swarf - a good half bucket full !
Then the chuck - well I certainly don't want to force any abrasives into it but it needed something doing. I used the same method as the guards but with even more caution. When the hydraulics are all commissioned I will be able to remove the chuck for a proper strip down and clean, but in the mean time at least the brown rust is no more.
