Yep, approved testing tool only...

Sacrilege.

As above, make sure the pointer is in the right place first,or you are shooting in the dark. Easiest way to do this is with a piston stop, it has been covered on here, do a search. Then, most V8s will tolerate 9 deg btdc on modern fuel.

Which compressor?

Looks cracking Ralph, very nice indeed

How are you running the engine? First steps would be to confirm the pointer is in the right place, they often aren't.

Very nice work

RAVE is all over the place, e.g. http://www.myrangerover.co.uk/rave-workshop-manual/ http://www.d-lander.com/manuals/ https://discoii.wordpress.com/resources/ Just the first few links.

Immoral, in what way? It is a 2a, yes With 2A chassis, engine, gearbox, axles...?

If it is just low current stuff, a cheap 24-12V dropper will sort you out.

You don't need to get the corners spot in, anything that can help with a hole saw will be good, but.... If you don't have one, just cut it at 45 degrees across the corner, you will find there isn't much material to remove afterwards. I think you may be over thinking this, and underestimating your skill and achievable accuracy of an angle grinder held in two hands, with your thumb guiding the blade on the guard. watch some the Binky stuff to get an idea

90% of steel bolts are already BZP, or Bright Zinc Plated, and most LR original stuff is either that or a thinner yellow passivated zinc coating on things like stead belt bolts.

Making a tablet play through speakers is just a case of fitting a small (2x25W in a SWB defender) car audio amp behind the dashboard somewhere and plugging it into the headphone jack port on the tablet.

I'd go in with a 4.5" grinder and slitting disc, roughing out the rounded corners, and finish with a file/finger sander/flap disc. You have much more control with a grinder than you'd think. BOM suggested rubbing a bar of soap on a grinding disc to help lubricate when cutting ali, I've not tried it yet, but does sound like a good thing to do.
