Making water cooled shoes need some advice about thin copper tube fittings.
I want to run some thin copper tubing around the shoe which will connect to the some metal fittings that will then connect to my rubber tubing and then to the pump and the radiator.
Now i know about the fittings that are available for the regular copper tubing that runs in houses but this tubing will be around 4mm and im not sure how to connect this tubing to my metal fittings which are about 3/8th of an inch i believe.
I was thinking to just use some epoxy putty or something but im sure there are better ways to do this. so any ideas?
im sure fittings are available but i dont know what they're called i couldn't get anything with a quick google search.
Edit: i didn't realise response here would be so thoughtful and all. I dont want to be able to walk around in these i just want to sit in my room and be comfortable. The heat difference probably wouldn't be too large between my feet and the air for a huge transfer so i also had thought to add a small water bath with a second small radiator init.
The copper tubing doesnt have to be directly under my feet i realise they'd probably be crushed otherwise. but the heat conduction through them must be so much better then the plastic tubing.
