I need a piece of 1/75" steel tube in 18 SWG about 450mm long. My usual place for bits and pieces now only stocks 10 or 16 SWG and the other place in town only sells whole lengths. eBay isn't offering anything either. Do you have a piece lying around or do you know where I can get a short length through the post? Ta!

ive got thicker, 1/8" i think so at least 3mm and a damn sight thicker than 18g

Its the thin stuff I'm after. I'd take 20SWG if I could find it but that really is a hens tooth.
