Jetboil – what is the absolute lightest Jetboil configuration?

My Sol Ti with sleeve (handle cut off) and a plastic lid from a can of nuts and the stove weigh in at 8 oz. I could remove that "stupid orange thing" from around the stove an lose around another oz, but it made my stove quite a bit unstable, so I put it back.

While I am not completely sure, I believe that using the Sol Ti will get you the lowest weight of any of the Jetboils, but then there are obviously still little hacks/changes that can be made to drop the weight even more.

Are you considering hacked JBs?

Sol Ti, SnowPeak GigaPower, Ti Wind Sleeve, and Ti heat reflector above the canister. I slotted the Sol Ti to accept the pot supports of the GigaPower. It all fits in the Sol Ti, and is contained with a snap-on lid.

A tad under 15 ounces, with the canister. And you could lose 1.5 ounces by going to a Monatauk Gnat burner. (Is there a lighter burner out there?)

That BRS burner is 25 grams.

I use just the bare Sol Ti cup and the Ti burner for a total of 7.32 oz. I don't think there are any JB parts lighter than the Sol Ti.

Any lighter than that with JB parts requires some mods. That stupid orange piece is something like an ounce but is structural. The piezo on mine has been convenient and reliable, so I guess it is ok.

Unstable… does not mean unusable… or unsafe… or even unstable enough to not be usable.

ps: the Sol Ti w/o lid, w/o stupid orange thing (tm, roger), w/o sleeve, and w/o base stand, is the lightest JB that you can have – unless you decide to get silly and resize your JB pot.

John, your video shows a best-case by using the massive canister – a lighter, narrower 100g canister on rocky ground would certainly not be as stable. Not saying it couldn't still work, just sayin'.

I pulled my Sol Ti burner apart to see what could be done, and the slop could be taken up by shimming between the pot ring and the retaining ring to take up the ~.015" gap between them. A triple wave washer would be ideal here, but I couldn't find one thinner than .020", which would be too thick. Here are some options for shims:

98126A541 (.015" thick stainless)
91124A058 (not stainless)
90902A228 (peel away in .002" increments)

Or if you really want to dial in the shim thickness to the last .0005",
3088A934

Those are all McMaster-Carr PNs, but of course you all recognized their part number format anyway, right?

What I wrote above would help with the largest part of the play in the burner assembly, but there would still be significant slop between the valve body and the air intake pipe (sorry for my lack of proper terminology) where they are held together by the spring pin. This play could be eliminated with some JB Weld between the two, or something less permanent if think you might want to separate the pieces in the future.

If you're talking about an "out of the box" solution, the Jetboil Sol Ti is as light as it gets. Mixing and matching from other Jetboils won't get you any lighter. Leaving the canister stand, cup, and cozy will of course save some weight without any major mods or impact on performance or function.

Swaping out the lid for something else is the most obvious "mod" and you don't lose much there. Why is it that Jetboil can't seem to make a half decent lid. I mean their lids just absolutely suck.

Beyond that, you have to really start carving up the pot or burner or swapping out the burner like Greg did.

Nice mod, Greg, BTW.

Greg,

How does the windscreen attach (or sit) around the burner?

It is a slotted Ti band that is a force fit over the pot support legs on the stove. It goes around the cup, then I slide it down. It is not easy to get the cup back on, but I manage. I just boil water, so usually it is not an issue.

I can only claim credit for the wind band. search BPL for the originating jetboil hack threads.
