"It's got me now thinking of a remote "mini" stove. I'm thinking something like the F1 or a Pocket Rocket or Snow Peak, but with the ability to attach to a PowerMax fuel canister.
There are the obvious advantages of a windscreen, but I'm thinking more of total system weight. The PowerMax canisters are much lighter. I'm going by memory here, but I believe the 6 oz. PowerMax canister weighs right around 3 oz. (maybe even lighter??) while my lightest regular canister is a hair over 3 oz., but only holds about 3 oz. of fuel. Particularly for longer trips, that's half the canister weight.
I know the Pocket Rocket is only 1.6 oz. with just the valve and burner assembly. I imagine the F1 is similar or even lighter. Sooooooo.....
How difficult would it be to turn a Pocket Rocket or F1 into a mini remote canister stove that could run on the PowerMax?? It seems you've figured out about every combination. Couldn't this be done for under 3 oz.??? I figure it could come pretty close.
Actually, now that I look closely at your picture, it looks like that's kind of what you've already done. Is that an F1 head? Also, you mentioned you figured out a way to attach normal valves to the PowerMax canisters. How? Finally, if you weren't going for cold weather performance, couldn't you leave the heater tube off? I'm thinking just a "normal" canister stove, but instead of sitting on top of the canister, it's remote. Am I missing some important piece here?
Hi Curt, One of the nice things about the Coleman F1 Ultralight (2.7oz) is that the burner head is smaller than most (lighter) but still a good burner. It will also come apart so the top part of the burner could be used like I have. You do need to make and adapter tube to mate it to some other stove parts. This required figuring out the thread size on the burner head and the thread size where you want to use it. Finding the thread size is not rocket science and stores that sell tap and die for making thread can do that for you. I email a lot with our new stove editor Roger Caffin and he helped identify some of the thread sizes for me and shared a lot of other good information with me.
Making an adapter for a really light canister stove such as the pocket rocket, the F1 and a few others seemed to me something that would be easy to do. Not, I got fooled, but not stopped. The key which I somehow missed is the valve body or gas control On/Off thing. That is what screws onto the canister and most are built into the bottom of the stove. To remote the stove you need to be able to disconnect the on/off control valve so it stays on the canister. That means you need a fitting or something on top of the control valve that has a piece of the correct type of gas line and that line goes to the bottom of you stove.
Most little stoves only come apart so you can do this by breaking them. Bad. It was an interesting moment when that light came on in my head. I don't know what stoves will come apart so you could do this. I have 2 little stoves like these and I haven't been able to take them that far apart.
This is doable but it may take a home made fitting or connector to make it work. At least two people are working on this.
Connecting the PowerMax canister to any remote stove can be done with a couple of fittings to mate the Coleman Mag Casting (how you connect the PowerMax Canister) Control Assembly/Hose line complete. You have to have all this because the PowerMax Canister does not have a threaded connector like all the other canisters being sold. You then need a pre-heat line or loop as on the Xtreme. For really cold temp's you need the pre-heat. The small canister stoves do not have a pre-heat system or I haven't seen one that does. By milling away a lot of the casting on the Xtreme I have the casting, gas line, control valve etc down to 3.67oz. I have to say that this 3.67oz set of parts is a one-of item.
I am starting to think that by the time you go to all the trouble to turn your little canister stove into a remote you could just make a 4oz remote stove like this one I just finished. I also think I can get the weight of this stove down a little more.
I think we need to have two stoves, one very light little sit-on canister stove for warmer weather at 2 to 3oz max or a remote stove like the one I made at about 4oz max. Then for cold weather the SUL standard changes and we add an ounce or 2 and go with the PowerMax system mated to the lightest stove/pot stand we can come up with. This might be the summer stove or another stove.
When I mate the PowerMax stuff to my 4oz stove I lose that gas line (about 2oz +/- a bit) but pickup the extra stuff necessary to use the PowerMax - add 3.67oz and the fitting necessary to mate the two. This weight should be should be somewhere around 6oz. I will not know for sure till I have the fittings.
