Can you explain why as i dont think the OP hasHe SPECIFICALLY in bold, doesn't want to use PTFE tape?

If 1000 people did this job 999.9 of them would use ptfe tape/liquid sealant and be done having a brew with their feet up after about an hour. I really don’t see why it’s being made out to be so difficult, other than the OP is maybe expecting absolute angular perfection from things which just aren’t going to be that way. When I’ve done stuff like this then there’s always an element of knowing when to stop tightening/tighten a bit more - it sometimes takes a few attempts but as said above it’s not rocket science.
If ptfe/sealant isn’t acceptable then I’d be questioning if the parts that are available for the job are the right ones. There are other ways of getting some air from one place to another if you are dead set against screw in fittings...
Seemed odd one has to grind the elbow, until the pan y dropped lol; as grinding the nipple does nothing to the angle. I.e. cut off half a male thread, then the female doesn't engage for that half a thread.The mating face on that elbow will always be in the same place relative to the male thread however much you cut it down. if you need to move the fitting 180° then measure the thread pitch and grind it down by half of that.
The bushes were just to get from 3/8” in the tank to the 1/4” pipe work going to the auto drain and direct drain.with all due respect I believe you are overthinking this. I have never heard of anyone grinding down threads to adjust the angle of fittings like that. It’s usually just a case of deciding whether to try for another turn! I would balance the effort against the risk a little more. If it leaks it’s a tiny bit of air. Where do the various bushes come in?
I have the hose its connecting with only 10 mm of ground clearance thats the issue.I didn't read it all....but you are relocating the drain point?
Go to a hydraulics place and get a flexible hose made up.
Install hose.

Hmm wish I had thought of the banjo idea.Is that a BSPP nipple going into the compressor? or BSPT?
If you're that pushed, a BSP Banjo would have saved a lot of room...and easily adjustable.
Or even a swivel elbow.
Thanks rejected that as 3/8” is 2mm thick. Clearance is 5mm with the handle lifted, so reducing it to 3mm ....If space is a bit tight try a bonded washer between the elbow and the bottom of the tank.
This is my chosen option ... to maximise ground clearance. Plus ordered a reducing elbow 3/8 to 1/4” hoping its a little shallower.grinding back the face of the elbow will make the fitting turn further round. you will just loose a bit of thread
I have had the benefit of doing an apprenticeship but don’t recall doing much in the way of formal learning with airline pipe fittings/ptfe - it’s just something you pick up I guess? I do remember doing it for the first time and it being “awkward” - but a few goes of trial and error and even I managed to have it weighed off.I'm guessing its a first time caller, sorry, user - when you first used tape, fittings etc, where you working with someone who gave you an initial steer on what to do? If you were presented with tape, fittings and told to install it with no previous knowledge or experience, you'd probably be a bit less than robust with it.
And I still see fitters winding the damn tape on the wrong way - and it annoys me!
Fit bigger wheels or put the existing wheels on a bit of woodI have the hose its connecting with only 10 mm of ground clearance thats the issue.
