any ideas for this...foil pipe?

[steveo3002]

need something that looks like this , about 8mm or so diameter


the real part is foil /metal tube used for heating ducting etc

[Red Firecracker]

You could wrap a 6 or 7mm tube with fuse wire and then wrap that with ptfe tape. I've seen that done to produce brake ducting/air ducting before.

why ptfe tape? can it be painted?

spose i could it with foil tape over it

PTFE tape will conform to the wire and give you the effect you are after and yes, it can be painted. I would imagine if you use foil tape you'll get creases.

Here's a link with the PTFE technique used;

any other ideas folks?

ive done the ptfe job for some bigger ones on the model , i need some around 3-4mm and its not looking accurate enough

If there aren't too many bends in it, how about the appropriately sized tension spring?

[zollburgers]

A slinky spring looks almost identical to that, job done.

[steveo3002]

they need to be bent alot , theyd not work that great

[zollburgers]

Ah, so something that performs similar to that rather than just looks like it. Can't you just buy some? I'm being serious, I thought they sell stuff like this cheap at any hardware shop?

8mm diameter?

[zollburgers]

Ah, I read it as 80mm. I can now confirm a slinky spring will not be suitable.

I thought it was 8mm you wanted?

[steveo3002]

yeh i did want 8mm...i used the wire and ptfe tape method that was posted for that

i tried to make some 3-4mm ish and its not looking so good

someone else has mentioned use a fine thread bold and bend it , or fine wire around a suitable elec cable

Ah yes I could see that at that size it owuld be aproblem.

I know some people use guitar (bass i think) strings to create flexible tubing, not sure if it goes up to 8mm though.

[steveo3002]

think ive sussed it...got some normal car wiring at the right diameter , then wind fine wire around it tightly and super glue in place , then paint to taste

Now that is a good idea, any wound guitar string would be suitable in various diameters. I expect the bottom string on a double bass is quite thick!

It's not thick enough. I used guitar string for all the oil and fuel pipes on my Bf109 engine.
