I don't plan on doing anything more than just using hose clamps. Based on your experience or knowledge of the products, which would you use. I'm not in a big hurry to do this as I have one that works, I just have an idea on how to improve upon the design. So if I had to order it I don't mind, I just want to order the right one.
I would use 1/2" OD copper tubing - especially if you are planning on a 50' length of copper for the coil. I've built quite a few of them and it can be a fun project.
Here is a LINK
to a story (web page I put up for a friend) on a chiller build that I did. In that case I used a 60' coil of 3/8" plumbing copper (1/2" OD) because I got it dirt cheap at the time ($10 for the coil). I used garden hose fittings from Lowe's for the connections. I just needed to drill out the hose fitting to fit onto the copper and soldered it in place.
I hope this gives you some ideas.
