I’m tidying up the pipework on a Simplex, most of which is 3/16”. What SWG should I use / is there a minimum recommended? The supplier I’m intending using lists 16, 20 & 22 SWG.

I use 22 swg straight lengths by 12 inches as supplied by Maccmodelsfor my models 3/16 and 1/8, bends nicely.

Thanks Jason. I tried searching SWG and a couple of other terms, but obvoiusly not the correct ones.

Just following up on this, is there any reason not to use annealed copper pipe- it is cheaper than the straight lengths and comes in a coil so longer single lengths?

It's easier to use straight lengths, and bend them, rather than trying to get the coiled tube straight, curves where it should be straight look awful, you would find out about pipe work if you modeled an NZR locomotive, all the pipe work exposed all over the boiler.

I've got a load of brand new copper pipe I'm trying to sell on behalf of a model engineer who has had to give up due to ill health. It will be a lot cheaper than retail. If you're interested, send me your email address by pm and I will send you a list
