How much inert gas do you need?
I have same question as well.
Is Nitrogen the easiest to get hold of (among all the inert gases)? ANd if so, how much Nitrogen do you need to CTB?
There's another thread (https://sanctioned-suicide.net/threads/how-much-nitrogen.4904/) about the Amount of Nitrogen for CTB.
I wish someone continues adding info to this thread or the other, regarding Nitrogen method.
In regards to buying nitrogen issue, i heard about Cyberweld from some thread here on SS (but now i can't seem to locate it; had too many tabs open sometimes and i lost track and just closed all after getting tired from researching stuff).
Anyone willing to share info/experience ordering any inert gas (such as Nitrogen) from Cyberweld, please post some posts on Cyberweld thread (currently there's one here: https://sanctioned-suicide.net/threads/cyberweld.20982/).
*EDIT: finally found it--> where i first heard about Cyberweld: https://sanctioned-suicide.net/threads/in-the-us-does-anyone-know-where-to-buy-pure-nitrogen.3220/)
**2nd EDIT: found another post where Cyberweld is quoted by

Please read my post directly above yours. That'll tell you everything you need to know.
If you need advice about buying a tank of nitrogen do the following:
1) Go to a website called Cyberweld...(D O T)...c o m which has been recommended here on SS before. I can't link directly because of the new forum rule about posting sources.
2) In the search box type in: inert gas cylinder
3) This will bring up a list of inert gas tanks you can buy in various sizes as measured in cubic feet. 20 cubic feet is the minimum size you need for this method. You can also buy a 40- or 60-cubic foot tank that will obviously provide nitrogen for a longer period of time "just to be sure" if you'd like that. ONLY choose a tank listed as "inert gas". DO NOT get one marked "oxygen", "acetylene", etc.
4) Click on the size of tank you're interested in. On the product info page for each tank there's a dropdown menu under the word "options". Use the menu and select "Full Nitrogen". What this means is that Cyberweld will fill the tank for you with N2 then ship it directly to your house.
Also for the tubing you need you can either buy oxygen tubing from Amazon or go to a local hardware store and buy a length of vinyl tubing cut to whatever length you want. I think the recommended length for this method is around 6 feet.
The internal diameter of the oxygen tubing should be a size that will naturally fit the barb outlet on the 02 regulator. If you go with vinyl tubing from a hardware store you'd have to first find out the internal diameter of the oxygen tubing which you could learn from the tubing's product page on Amazon then choose vinyl tubing that has the same or similar internal diameter.
Ready-made oxygen tubing that you buy from Amazon or a medical supply store is usually all of the same internal diameter and designed to already fit on the barb outlet on an oxygen regulator.
Generic vinyl tubing you get from a hardware store comes in several different internal diameters so you need to make sure the tubing you buy fits onto the barb outlet of the 02 regulator. The way to do this is to buy the regulator first then take it to the hardware store and attach different sizes of vinyl tubing to it to see which one fits tightly to the barb outlet.
If you go with generic vinyl tubing go to either a hardware store or an auto parts store and buy a small hose clamp that goes around the end of the tubing attached to the barb outlet on the 02 regulator to make sure it doesn't slip off when you turn the gas on.
