Well, I decided to make another ti stove, this time resembling the TiGoat WiFi stove. I wasn't going to go this route because there are a number of things that gave me a bad feeling about that design like... 1st - using foil was kind of scary right from the start. Whether for a stove pipe, or the stove, it just seemed too flimsy. I have since found that when used with caution, it does seem safe enough. Certainly nothing like 16 gauge steel, but safe enough. 2nd - the door(?) and draft allowed no control over the fire. A piece of ti foil hanging over the door opening didn't reassure me. So, I changed some things to my liking. I was going to use the 'pot hole' method and just use a stainless steel lid as a pot hole cover... then decided to just go with a slide open door on top. For the draft I chose to add a couple folds in the foil body and include a sliding draft door, this way the foil stove body will still roll up for packing as long as the draft door is removed. I chose to make a sloped (30*) stove pipe nipple so I wouldn't need to carry an adjustable elbow. I stayed with their 5" from the ground measurement, but added Tee nuts to the bottom of the legs as well to keep them from sinking. Lastly, I made a foil liner for the bottom of the fire box to keep the stove bottom from warping. I was happy that the stove top door did not leak smoke as I thought it might, but any time I wanted to crank up the heat the stove would start huffing. I've burned wood long enough to know that there are a number of things that can cause this. In this case I blame it on the 3" stove pipe and the fact that it is thin metal that cannot hold heat. A hot stove pipe means an easy draft. I'm going to research items that I can use as an insulator... like alum foil, reflectix etc.

I really admire what you're doing with this. What kind of time commitment do you have in this stove? I assume it fairly high.

Thanks.
Well, if you include the time waiting for ti to get here from Canada I'm looking at several weeks. If I had all the mat'l in front of me it'd be a few hours of puttsing in the shop. Most all edges are de-burred to keep from cutting one's self or other gear. Threading aluminum (legs) takes time because it wants to gum up. There are angle clips inside on all four sides of top and bottom to keep the sides from caving in. A lot of it is hand cutting so... it can get a little tedious.
It's a great project for a retired person.

Are you going to apply the same iron leg technique that ended up on your other ti stove? As I recall the aluminum didn't fit the bill.

This one was patterned off the WiFi and has aluminum rod for legs. Aluminum works on this stove because the legs are far enough (I hope) from the biggest share of the heat. If they fail to hold up, then steel rod may be in order.
This is a stove that I would be willing to take on most any trip that might be cold and wet. It's that light and the bulk is minimal. I plan to carry it in my Ruck sack. I will try posting better pic's at some point.

Wow, impressive. My sewing machine can't make anything that cool - or would it be, that hot? Anyway - great stove!

There's a special attachment for making titanium stoves, kevlar canoes, carbon paddles etc. Leave it to the Swedes! ;-)

Portagekeeper: I was wondering if you could tell me what thickness of titanium you used on your stoves. I was looking on the McMaster Carr web site and they have it in sheets that are in increments of 1/16. Also, what thickness shim stock did you use for your stove pipe? Thank you!!!!!!

This stoves top and bottom are made from .020" thickness ti and the wrap around sides and ends along with the stovepipe are of .005" ti. Ti Goat now has some .008" foil for stove bodies. They are the only place that I've found this foil and I'm really interested in using it for my next stove - although it all costs $$$.

have you considered skipping the legs and just using rocks/small logs to keep the stove elevated?

Well, the legs are what hold the stove together so I don't see an advantage to that. I have made other designs since this one and now use ti rod for the legs - always trying to make a better mouse trap.

got it - the 'legs' are a part of the frame structure - thanks!

btw - I like the 'feet' on your build, which the WIFI seems to lack - nice!
