Regarding hot tent stovepipes - Ti disappointed.

[Ascobis]

(I couldn't find a similar thread. I couldn't find a better topic under which to post. Thanks for your patience.)

I mostly camp with a tarp. I got a bonus and spent it on a hot tent, stove, and cot. The tent is meant for a hammock, but works with a cot if there are no suitable trees. The stove is titanium, as is the stovepipe. The stovepipe is the present topic.

I ruined the Ti foil that came with the (very good) stove. I searched the web and found the secret method of doing a foil stove pipe right the first time. (Talcum powder and patience).

Great, now I have an unwrinkled 3m x 6mm stovepipe, loaded with two stovepipes' allocation of rings. Let's play in the cold. Winds were 40kph, gusting to 55kph, changing from W to NW through the night. Problems: The provided guylines made a large angle to the ground, /|\, so the force applied to the guy was mostly directed to the vertical component. (Non-maths geeks: Tautness of the guy pulled the stack downward against the stove and didn't resist the wind well) The rolled foil had a straight bit that stuck out and caught the wind. The wind-induced oscillation caused the stovepipe to touch the edges of the stove jack hole. One rigid end, one oscillating end, and an intermittent force applied transverse to the pipe. The pipe made a very loud, sharp, "Crack!" and collapsed about 5cm of pipe into a 2cm length, right at the stove jack. That'll never roll up again.

I suggest that titanium foil stovepipes are not fit for purpose. In total calm, with long guylines at 30 degrees or so from the ground, Ti foil might be ok. In the bush, no.

I've got 0.5mm thick stainless steel pipe in my Jungle River cart. I've added a section that has tie-out rings to the order, to place about halfway up the stack.

This isn't a whinge, it's a learning experience.

Cheers,

Not something I've messed about with yet but good to know for reference. I've final got a stove jack for my tarp.

I am fairly hesitant with anything Titanium if it’s 1) thin and 2) going to be exposed to high temperatures.

My Titanium bushbox has warped. I just don’t think it’s made for these applications, as tempting as the weight savings are.

I've looked enviously at expensive ti stoves, as I like to keep my kit as light as I can, but I've never been convinced that those rolled up stovepipes were any good. A nightmare to get rolled up, and just too lightweight to hold up to any strong wind. I do like my little outbacker, and my anvay, both very robust, never warp, stack is robust and rigid enough for high winds not to affect it, as long as its guyed properly.
Only drawback is weight, but then to my mind that's what makes it safe and burn much more effectively offering better heat retention, and radiation of warmth from the stove for longer.
I guess you have to decide what is more important, reliability in bad weather, (and if you have a stove, that is more than likely, ) or weight saving, and possible failure in high winds.
I'll stick with my outbacker. Cheap and cheerful, solidly built, and, if it lasts as long as the anvay, worth every penny.

3 metres at only 6cm is very long for a small diameter.
for comparison, my Seek Outside medium stove has a pipe cut for their Cimarron 2m tall tent at only 2m tall. Their chart suggests a 3m pipe is 25cm longer than what they use for an 8 person tipi.
I agree that what you wanted to do was not suited to a roll up chimney, but concluding that titanium roll up chimneys are universally unsuited for the bush is too much. The two companies I know that sell such chimneys (Seek Outside and Kifaru) have hard won reputation for bush proven gear. They don’t market to fair weather campers. Their market is hunters, particularly mountain hunters, who use their tipis and stoves in some pretty remote and windy places in autumn and winter.

There is lots of outdoor gear that is used successfully which will fail if used in the wrong manner….especially light weight gear.

If anyone wants a titanium stove with a tube chimney, check Four Dogs.

The lid on my titanium tent stove is warped, but it pulls flat enough when bolted together. So what, I don’t need perfect flat, and I am not convinced that a similarly thin stainless steel stove would not warp. Generally, from an engineering perspective, titanium is very good at high temperatures, losing little strength and no corrosion resistance.

I simply don't guy out my rolled Titanium flues, I use the silicone roof boot to secure the top of the flue. I think you have to treat rolled flues as a replacement maintenance item. Tip from an American site is to roll the foil over a length of PVC plumbing pipe the first time and fire it up immediately. I may have to try that next time I need a new flue but I haven't burnt out my first one yet as the tiny stove actually gets very little use

No problems with mine, took my time guiding and folding in for its first burn and it does exactly what it should do, rolling up and down. I avoid the edges carefully and use rubber gloves which offer protection and can be disposed of when covered in soot. Come to think of it the best option would be some leather gloves with rubber over the top. I might try that next time.

I don't guy mine out but have it held by the tent stove jack which has always pretty solid. The chimney length is 2.35M which is shorter than yours and would be less of a lever.

Winds gusting to 35MPH is o pretty high in any circumstances and I would have been thoughtful on erecting it and it does raise the point that once set up and the wind picks up how easy is it to kill the stove and bring the chimney down?

I value space and the ability to create a full length stove pipe out of a tiny package still amazes me.

Was looking for something else and found this. That is a rolled titanium chimney, at the correct height for the size of tent. No extra guy lines.

The tipi in that video really did need all the guys fitted and taut and it wouldn't have moved so much. But putting the flue as close to the pole as possible makes so much sense in a single pole tent
