Re:

Can the rings be removed from the crank?

Measure / find the bolt centre diameter and go shopping. Just about any ring will work but narrow-wide should help stop the chain falling off.

Or just leave it as it is? Any harm in hauling around a few grams of chainring that you don't use?

Like Rick says if they unbolt you should be set. Have a look at snail rings on eBay, I fitted one on my fsa cranks. They seem well made and they don’t cost much. Make sure you get the bolts too as the current set will probably be too long.

If youre putting the ring in the middle position, why not take an old outer, grind off the teeth, then run that as a sort of guard, plus means you dont need to buy any more bolts, ie shorter for a single ring.

Donkeys ago(about 97, i built a lightweight all alloy runabout, with a 1x8 set up. Did as above and used a ground down outer. All worked fine.

I think using the middle position helps run through more of the gears with a lesser chain angle than if placed on the outer position. Less chance if it picking up and chucking the chain off the ring.

Re:

I think I’ve got a few cranksets in the spares box you are welcome to a set for postage? Let me check what I have tomorrow and let you know.

Re:

Ok I will enquire about postage, never sent anything outside the uk but apart from cost I cannot see why it would be any different.

Yeah, drilling out the spotwelds will free the granny from the middle. At a guess the big ring is held to the middle with that ring of 5 single spots.

Only thing i can think off that might leave you unstuck is that your middle ring is ramped, so it may drop the chain more often/quite easily unless you are very careful with chain length.

Re:

Order a snail chain ring off eBay for £7 delivered, mount in place of the middle ring. It is a thick/thin tooth design to prevent dropping the chain.

I ran one for a year with no noticeable wear on a 1x9.
