Tips & Tricks -Upright Canister Stoves in Cold Conditions

Its winter here in Australia and that means sub zero conditions in the Southern Highlands and Snowy Mountains. Cold is the enemy of my Jetboil because as low temperature makes it more difficult for the gas in the canister to evaporate and the pressure is reduced.

So off to the internet to look for solutions. I was initially looking to see if there was an adaptor available to make the canister ‘remote’ in the way my old epigas alpine stove used to be. Instead I sumbled across a much cheaper DIY option that is genius in its simplicity – the Heat Exchange or HX Strip

This info comes from the Backpackinglight forums and the thread I got this info from can be found HERE

The concept is super simple. A copper strip is strapped to the side of the canister so that one end is in the flame. It conducts heat from the flame to the canister.

On the BPL forums it seems to have gained the name the Moulder Strip after the chap who brought it to everyones attention and optimised it. Its also been known as the Alpine Bomb.

The picture above is the best itteration I’ve seen and the one I’m looking to copy. The things to note are:

  • The shape of the strip is super simple (easy to both make and pack!)
  • This will work on any upright canister stove I can think of
  • Its very lightweight, infact an upright canister stove with HX strip will be a lot lighter than a stove with remote canister
  • The HX strip is tightly clamped and shaped to the canister with a good contact patch. This is key for optimal heat transfer
  • The velcro strap is protected by a bit of heat resistant silicon to prevent it melting
  • The system can be easily added or removed from the canister to allow changing and use in variable conditions. (This should only be used in cold conditions)

Copper is the best material to work with for this. Its a very good thermal conductor, it has a high enough melting point and its maleable enough to be easy to work with.

Aluminium can work but needs to be twice as thick because of its reduced thermal conductivity. It is available from Bunnings though, copper is not ­čśŽ

What do you think, let me know in the comments

Forces in White Water Rescue

I participated in an Aquatic Rescue course last week and it had me wondering what the various forces involved are. After a bit of internet research here is a collection of bits of information that I found interesting. I can now apply some of this to optimising the equipment I carry and how I use it on the river.

Warning this is a pretty nerdy and long post. Grab a brew and settle in for while. Continue reading

QR Codes – 5 Uses for Outdoor Instructors & Centres

QR Codes are those square pixelly things you see on a lot of marketing material. With the right software you can scan them using the camera of your phone. You might already use them quite a bit. They used to be a bit faffy to use because you needed to find an app blah blah blah. Now in iOS Apple devices they just work straight out of the camera. In this post I’m going to suggest some ways they can be really useful for outdoor staff and centres.

Try scanning this QR Code with your phones camera

Fat-Skeptic to Fat-Evangilist in just one bike

In May last year (2012) I had a go on the fatbike that Andy had brought to try on the sand. I was very fat-skeptic.

“Of course a bike wont work on the deserts soft sand”, I thought.

Oh how wrong I was. From that brief play on a small dune just outside Arabian Ranches I almost ran home and started googling everything  could about fatbikes. There wasnt much about using them on sand, most of it was about snow biking and the growing interest around the world in riding the 82mm rim / 4 inch tyre combinations on trails.

I came to the conclusion Continue reading

Dear Blog – please accept my apologies

for I have been neglecting you for far to long.

Starting with this post I aim to make it back up to you in some small way by paying you some attention.

My excuse is poor, I was initially distracted by glossy print and then suffered a bit of writers block leading to me not writing or producing images of anything for anyone, not even you dear Blog.

So to make amends I’m going to start a new page detailing my new found enthusiasm for cycling in the desert. I need to tell you all about it, about some big adventures I’ve had and about future plans. I’ve got some plans to use video as well as photos too so we’ll see how that goes.

I intend to spend plenty more time in Oman surfing this summer too. I felt like I missed out last summer with all the visa and passport malarky to start off with and then not being at home much as the summer wore on. I will have a root through some of the photos from last summers travels and share the better less boring holiday snaps with you too, I’ll not to over do it though, most holiday snaps are only interesting for those who were there!

So enough apologies, action speaks louder than words.

Ian
