Self build smoke unit material help.

I’ve been playing around with the standard heng long smoke units and some DIY ones with varies results. My latest idea is to move the heating element actually into the exhaust. See video where I have put a heating element into one of the exhaust of a Tiger 1.

I think the effect works well, even before the addition of a fan. Problem is the element does gets hot and started to melt the plastic after about 10 minutes. So I need to figure out a way of fixing the resistor in place with out touching the plastic which leads me to wanting to know what materials I can use which is heat resistant.

As space is tight, I was thinking drilling two holes and using these to support the resistor legs, but the legs get hot so need something to bond/hold the legs but will protect surrounding plastic.

Hi Tankbear. Thats one sweet looking mod you have going there.
I know my local model shop sells various diameter copper tube.
May this might be what you are looking for. After all you only need that to be copper where the element is, the rest could be your normal tube you use. Just a thought any way.

Good luck with the build.

Caddyshack I had thought about metal tubing but think is would conduct the heat more (reducing the heat at element and less smoke).

I had a look around the stores at work earlier to see if I could find anything suitable. Found an electrical through crimp (not certain if that the right name). Need to see how well it resist heat but if it does I think I can make it work. Will post some pictures if I get chance to work on it this evening, as I know difficult for people to follow otherwise.

Had some sucess with the bits I found. Think the pictures below better explain it.





Only problem is for some reason it doesn't make as much smoke as before even when blowing across it.

Back to the drawing board I think.

How about making using miliput to make ' ceramic ' mounts ? - it takes heat well .
