I'd cut a bean can to make a liner and resize the piston on the bench grinder

Thelabstore do all the spare parts for them.
Probably cheaper to buy one with a dead motor for parts though.
Before getting too far in I would want to know what's caused it to do that in the first place in case that's not the only/original problem.
Unless it's a single pot whip the other one apart and see how close that is to destroying itself as well.
You could measure it up and see if you can get a liner/piston for something else that's close enough to fit?

you could probably buy a second hand one for less than the cost of a new piston and barrel I would try to sleeve it or do as @hotponyshoes says.

It would be worth asking them for a price on the parts, just so you can let the rest of us know for a laugh if nothing else!

I think they can get all the parts, if you can find the manual/parts list and email them the part numbers they normally get back to you pretty quickly.

Bean tin it is then!
The other side is fine. This was caused by a faulty NRV apparently...
I've been trying to get parts but no one can get them. Best I've found is around 2.5k +vat for the whole unit. Laugh it up guys!
I've found a liner that I can make fit and I can *probably* cobble a piston together but by the time that's done and I've bought two lots of rings and gaskets, I might as well buy a new unit!

where did all te swarf go....?
not having a go at you, more a general remark, but how can things get to this point without someone questioning things... did it perhaps not sound just a tad rough running prior to eating the cylinder completely??? surely the noise (bag of spanners) would have made the owner question whether all was ok??
in the workshop, I see this regularly, bearings destroyed to the point that the casings / housings were demolished completely... just had a wee Bosh electric mower in on monday, just stopped he said.... ok have a look, bottom bearing nothing left only the inner race on the shaft..., plastic housing melted, shaft tipped over to one side, partially jammed and overheated the motor and that in turn melted top bearing.... nothing worth salvaging, scrap...I always ask the same question, surely you must have heard it, well it was a wee bit louder than normal.... loud !! it must have been screaming for it's life..... shame, really if they brought it in earlier, a 5 quid bearing and all would have been rosy again... now their into it for at least a couple of hundred for a new one... ok I repair stuff so it's work for me, but all the same.

I completely get what you're saying. It's not in my workshop but on site so I rarely see it and the people who are using it wouldn't know what rough running sounded like.
Apparently the only reason it was discovered was because it was running more often than usual - presumably because only one cylinder was working.
@Morrisman - they do look brassy. I didn't think brass liners were a thing and getting info out of Jun-Air is nigh on impossible!
The swarf is sprinkled round the inside of the cabinet. It's really rather attractive.
So complete opposite to my mum . . . spin dryer bearings are squealing, can you take a look?
I can't hear anything to be worried about . . .
I did once advise an apprentice the slight drone from one front wheel bearing would be okay for little while . . I got a lift with him a month later . . . couldn't have a even a shouted conversation over the noise from two extremely bug gered fornt wheel bearings . . .
knowing we all like a photo, nipped out to the scrap pile, and took a few .... A wee bit louder than before he says..... aye right
.. the screeching must have woken the dead, never mind the deaf... given the stink of burnt plastic in side the casing, must have been smoking a fair bit too.... but hey lets just keep going eh...
