avalibility of thin ti rod - 01/26/17 04:45 PM

I'm doing a bit of day dreaming about a wind screen for my stove set-pocket rocket & 750ml Ti pot. In the past I've used a premade heavy aluminum foil wind screen....as of last outing it's worked fine. But, it surrounds both, the burner as well as the butane tank. So I normally prop up the screen so that fresh/cool makeup air is drawn into the area of the canister. It's worked OK...but this approch seems way too precarious to leave un attended. ( and then the top of the screen is needlessly way too high to do anything) So I'm thinking that in addition to cutting down the existing screen and elevate it using Ti. rod. The rod from most all supply places seem needlessly expensive and way too big in dia. It occurred to me that perhaps flux coated electric welding rods might be an reasonable approch, after I crush/clean the flux off. Has anyone bought them from their local welding supply house?..thinking I'll need three rods approx. .063 dia(1/16").. Finished length, about 8"

I don't think that Titanium welding rod is available flux coated and, even then, you would probably have to buy a half pound or more. 1/16" Grade 2 Titanium rod is available by the foot at McMaster-Carr Supply.

A two foot piece is $3.05, but you would probably have to pad the order out to keep from getting killed on shipping. Grade 2 Titanium is soft and can be bent. Grade 5 is harder, but isn't available in 1/16" dia. I've used 1/16" Stainless steel TIG welding rod to make little skewers and stakes before. It's heavier than Titanium, but easier to find. If you know of a welding shop somewhere, they might have some stainless TIG rod. I doubt that you will find many shops that weld Titanium unless you are in an area that has aerospace industries. I find McMaster to be a handy source for small quantities of difficult to find materials like Stainless Welded Wire Mesh:

I have used the 2 X 2 mesh to make a pot support for an alcohol stove. It can be cut with tin snips and rolled into a cylinder.

I use a tent stake or two--multiple use. Of course it won't work if there's a big storm threatening to blow the tent down, but in that case, I probably won't be trying to cook anyway. More like battening down the hatches, crawling inside, and waiting until the storm is over.

My windscreen goes only 3/4 of the way around the stove, which is sufficient opening to keep the fuel canister from getting overheated, a big danger when using a windscreen with a canister stove (an exploding canister can ruin your day!). I do feel the canister frequently, just to be sure. This setup works well for me. Obviously, the opening is on the downwind side.

I presume you're not leaving the stove unattended while it's on!

I wasn't in tune with the differences between types 2 & 5. My intentions are that the rod is to be pushed into the soil about 1 to 3 inches. Along with some bending. I do have some gas welding fill rod in stainless and 4130 steel both are 1/16". I'll probably try using one of those, and make do. And revisit this project next year. Thanks all! P.s. " un attended " is one if those words that can mean a lot of things.....I do divert my attention from time to time...I'm pretty sure we all do this

Even though McMaster lists the Grade 2 Titanium as soft, I don't know how soft it really is. I might get some just to see. I've made windscreens from aluminum flashing for alcohol stoves and used stainless skewers for pot supports. I'd like to see how the Titanium rod compares to stainless.

You might consider using aluminum welding rod. It weighs half as much as titanium and is plenty strong for your needs. All welding supply stores and likely Home Depot in the welding dept.

I guess I don't understand your "heavy aluminum" design. Mine is narrow enough at the bottom so it doesn't slip down over the canister. I leave one side (downwind side) open so i can reach the control and plenty of air gets in so the tank doesn't over heat and there is plenty of make up O-2 for the flame. The foil fits around the pot loosely so the hot air escapes around the pot.

Probably a poor choice of words. the last few years I've been using a premade wind screen....it's not heavy- more thick to withstand the daily folding up and unfolding. About 6years ago i bought them online...it was a twofer deal. (after four years, the second shield is still unused). currently it sits on the ground and is long enough to shield the burner assembly and extend almost to the top of the pot. if I were to cut off about three or four inches from the bottom and use the 3rods to elevate the shield so that it shields from about the "turn" of the fuel canister up to the top of the pot. the ideal imho. this would shield the burner/pot as before but also allow more cooling air to flow over/around the fuel canister. currently I leave the overlap open to allow air for this. with that seam closed I think a fair amount of fuel could be saved. The weight of both setups are probably a wash. this year I didn't get around to making the change...but this sort of thing is perfect for winter indoor activities, and has been added to the list.
