I don't suppose any of you metallurgist types have an eight and a half inch section of c12mm brass tube going spare? So far I've ordered from amazon only for it to be 'lost in post' and from the bay which, after nearly three months has now been declared 'lost in post'.

Yes, I was on their site earlier, £18 they wanted! I'd want it in solid gold for that, not just gold coloured!

Have you got any model shops nearby? They always carry a good selection of brass rods and tubes for the steam engine people.

Thinner, but it depends what you want if for.
That might do it

I need some brass from metals4u, so if you can't get any sorted before the end of the weekend let me know. It is not far from me, so I could collect mine and chuck yours in the post. I would expect that it will be the end of next week for them to get the order together though and a couple of days to you.

You know, much as I love living here, it's dreaadful for buying anything that's supposedly commonplace elsewhere. Unless it's horse-related!

its an interesting thought, but I dont think that you are alone. I have a short list of things that I have been looking for and really struggling, eg some western red cedar or larch but I can't find anywhere local that I can collect from under normal circumstances (I only want a small quantity of longish lengths), one of these famous small places that sells metal offcuts and will weld for a couple of beers...

If your bio is correct and you live in Lincoln, thats farm country, there will be steam enthusiasts all over the place. Time to start meeting people at the pub (from 2 metres away of course) :lol:

Is that the same place you picked up the iron pipes for me? Thanks for the offer, the link Phil sent looks like it fits the bill; I've just fired off an email to confirm the inner diameter.

Yes, there's a model enginners club not far from here; the mention of model shops reminded me I spoke to them a few years ago about something or other. Their website soen't appear to have been updated since.

Hi Lonsdale73.

Yes, I have "a" length of 12.7 mm brass tube approx 12 inches long. The wall thickness is 0.25 mm, so if that's too thin for your job, I have another length exactly the same which is a tight sliding fit into the 1st piece. That also has a wall thickness of 0.25 mm also (so making a 0.5 mm wall - obviously!) and if that's not enough I have a 3rd length of 0.25 mm, ditto sliding fit into the 2nd, to bring total wall thickness to 0.75 mm (+ whatever slight extra thickness sweating it/them together with solder would make - I've done that trick several times and it does work OK, and - surprisingly - it does cause the OD of the finished tube to swell very slightly).

Where did I get it? As 2 posters have already suggested above, from the local model aero shop, and not hugely expensive I seem to remember.

You can have the 3 lengths (if needed) for nothing, BUT there's a rub (always is, isn't there?)!

You would need to repay the postage and while I've seen several gripes on here about the cost of UK postage charges recently, you lot ain't seen nothing until you've seen Swiss postal charges! I haven't checked, but at a guess (and I do have some past - bitter - experience) I'd say you'd be looking at at least the equivalent of 20 quid if not more, for tracked air mail.

Up to you, the offer is open, but at a guess I'd suggest you try local model aero shops yourself - some do mail order, and should be cheaper than Swiss Post.

If you don't know any local shops, try mags like "Radio Control Models" and/or "Flying Scale Models" for lists of shops all over the country (used to be "free for a gander" every month on the shelves at WH Smith, etc).

I would expect the Beaufort stuff to have a similar wall thickness. No pen kit maker is going to have mill runs of bespoke tube made. I know it is thin walled, .25mm feels about right.

Yeah, agreed.

I don't know anything about pen kits, but model shop stuff is always (nearly always?) thin wall stuff. When I needed thicker wall stuff (back in my aeromodelling days) it was always a hassle - usually had to find metal stock holders willing to sell "little bits".

Same with copper and ali tube too - but the model specialists sell (sold?) tube in "nesting sizes, so you could build up wall thickness that way. OK for models (usually), but maybe not if the job's more "heavy duty"?

That's about right marcros, I've just checked the tube on a pen kit, not quite 12mm but thickness is no more than 025mm.

If it's suitable then Phil at Beaufort provides a very good service and would get it out quickly, might be worth the OP giving him a bell
