Yeah diameter, about 2m length. I've been to the local plumbing trade places but it's all push fit plastic now.
can i ask what its for and what gauge ? My old mans a copper smith and may sell you a bit but it ain`t gonna be cheap !
Does it have to be copper? Prices have shot up in the last few years, we get 1000's of pounds back each year just from weighing in our copper swarf at the scrappy. Could stainless be an alternative?
Stainless works, but, you need copper in the system to remove the 'bad' odours and chemicals also I can't weld stainless. Lol. Traditionally all pot stills and reflux stills use copper. It's just a pain the price of copper is so high.
Jewsons next door to us @ work sell copper tubing, we bought some the other week, was only a few bob for a 2m length of 1" bore pipe
I want to try some whiskey/bourbon (corn liquor or sour mash) and rum. I've got a pot still for the rum but it's not right for the whiskey. Also making neutral (vodka basically) you need to distill the ferment numerous times to remove all the flavour. Hence vodka is 'triple distilled', that's what a reflux still does. Multiple distillations in one run.
