The jump ring I use for my bail in the course demos is listed in the raw materials, but this is a discretionary item depending on what you want to use for stringing material.  Any size jump ring will work (or more tubing!), though I recommend at least a 16g thickness for structural integrity.  

Let's talk TUBING:

You may be wondering why you need two tubings that appear so similar in size, and I totally get it.  The list calls for 3.56mm outer diameter (OD) tubing as well as 3.66mm OD tubing.  Outwardly, these appear almost identical. 

The 3.56mm OD tubing is a standard heavy wall tubing with a 2.54mm inner diameter and a .51mm wall thickness.  This will work for setting your 3mm stone.  I chose this size because it works within the "windows" or holes that most of the coins I have on hand feature, so it seemed a good choice for kits.  There is nothing else magical or mandatory about this specific size, and if you wanted to choose a different size for your tube setting and corresponding stone, by all means do so!

The 3.66mm OD tubing is an EXTRA-HEAVY wall tubing.  It has in interior diameter of only 2.03mm and a wall thickness of .81mm, much thicker than the above version!  This is the tubing we are using for the ends of our swivel frame.  Because our frame has to accommodate spinning pins and risks getting knocked around when worn, possibly enduring torque, tugging, and who knows what else, I wanted a very thick material that would ensure the strength and longevity of the design and your resulting piece.  This is therefore not an aesthetic decision but a functional one.

That being said, if you find it hard to source the 3.66mm OD tubing and want to try a regular heavy wall tubing instead, you certainly can.  The 3.56mm version would work as an acceptable substitute, and hey... two birds with one tube!  Just know this is a more fragile option over time, and you may find it a bit trickier to work with when you get to the soldering steps for the frame assembly.  Bottom line: I always believe there is more than one way to go about doing things, so if you need or want to make substitutions, know you're not really stuck and I'm not really strict.  

Remember you can message me if you have questions about any of this!  Hope this helps and can't wait to see what you create!
