Can anyone put me in the way of an old oxygen concentrator?

I've been doing lampworked glass on a propane torch, but if I could lay my hands on a concentrator I could get a bigger, hotter torch and make bigger beads, faster! You can buy recon concentrators for this, but they're pricey...

I need a supply minimum 5 lpm, 10 would be a bonus.

If you want to see what I've been doing, here's a link to my Etsy shop:

Any help much appreciated.

Thanks,
Moira

I have been on the look out for one too for the very same reason. They are very scarce and pricey but good luck

Thanks!

You're not another obsessive glass melter are you?

My wife went to a taster session at a local beadmaker and has been back for a few of their open evening when they let people use thei equipment. Now she wants her own kit.
I am in to stained glass and slumping glass in a kiln.
So no I am not a melter - unless things go wrong.
