Yeah, copper is cake and I have no issue with .035 stainless either.
Bobby_M said:I have a similar bender and I get buckling with .028, nevermind .020. It's a 3" radius mandrel. What's your secret?
If it's not the bender you're using it could be the tubing manufacturer.
so just to be clear though, you have actually used the bender on the 304 .020 stainless tubing from grainger that people have been buying (referenced through out the thread). Sounds like Bobby is saying he has tried it with little success (albeit with a different bender and different tubing).
That's correct. I would bend a piece if I had one in stock but it's not as common and more expensive because of that. .035 is standard. It also depends if you're bending straight or coiled tubing (beverage line) which is typically softer for bending applications without kinking. A picture below shows the most prone spot that I can imagine where the kink might occur. A small indent in the tube is common but has never been as far as kinking or collapsing. After that circled spot, there really is no room for the tube to do anything other than stretch because of the dies. This is all just from experience with what I've had.
Thanks for the info. You say the .035 is more common and less expensive - I haven't seen roles of .035 for less than .020. I of course am referring to coiled tubing.

That looks great do you sell those?
Stainless if I order a 25 ft at 12inches in diameter how long will it take to ship out?
Fair warning, stainless steel loses its stainless properties if it gets too hot. I know this is an issue when welding, but I don't know at what temperature it becomes a problem. I'd guess, though, that any heat high enough to anneal it would likely be hot enough to ruin it.
Hello,
I am following the guide V-Twin created and made myself a jig to coil my stainless steel. So far I have had moderate success. I have coiled down the diameter 2-3 inches so far, but I can't get it smaller.
The issue is I can't seem to find the right balance between too tight (where I can't move the coil through) or too loose (coil moves through without going tighter).
I have noticed that the nylon locknut grates against the middle pulley when I have everything tightened down, anyone have any suggestions on how to prevent that?
My only other thought is that my pulleys are maybe too deep? They are the 1/2" rope pulleys suggested in the guide. I have spent a couple of nights thinking about this, it has become an obsession. So far the coil is in good shape so I haven't totally effed it up yet.
Thanks for any assistance.

I have done this with a v twin inspired coiler i made. I wish stainless brewing was around before i put everything together. spend the few extra bucks and save yourself a ton of hassle. that said i have done done any business with stainless brewing yet.
