Whiteburn's Wanderings

One man's wanderings backpacking around Scotland plus the odd digression

Duomid Pole Jacks

In a reply to a comment on my post MLD Duomid First Steps I mentioned that I had tried an ‘A’ frame set up using my Leki poles & 30cm (12”) pole jacks, thought I’d share how I made up the jacks.

I’d some 16mm diameter * 0.9mm wall aluminium tubing (measuring it up accurately it’s probably 5/8” * 20g) which I was sure was stable enough to take the bending load introduced by the pole angle (~60 deg) the only issue was how to get a snug connection with the Leki’s tapered plastic pole tips.

My initial though was to make up some DIY ‘Sugru’ (Corn starch + silicone sealant) & mould a tube plug that match the pole tip but after finding a silicone sealant  cartridge that hadn’t ‘gone off’ I noticed the screw on nozzle was just about the right size to fit inside the tube to act as a packer.

After digging out the silicone from a couple of old nozzles all that was need to get it to fit was a bit of trimming with a craft knife.

The inside diameter of the nozzle was too tight for the pole tip so now came the technical bit, I gently heated the aluminium tube with a hot air gun until the plastic insert was just pliable and then pushed the tip inside effectively moulding the plastic insert to match the tips shape.

Once cool the tip was a very snug fit into the jack with no discernible wobble.

The bottom cap was whittled down out of a plastic door stop

At the apex of the A frame I just tied the handles together with a figure of 8 lashing, a very light weight (4g) but not very elegant solution.

The result proved very stable & definitely opened up a huge internal space under the Duomid, it did take some faffing about though to get it set up (I’d perhaps improve with practice) & there is a weight penalty, 82g for the jacks + I’d need to have the Leki’s rather than my favoured Fizan poles.  In winter though I’ll often use the Leki’s, opting for their brute strength to guard against a bending a pole amongst hidden rocks buried in the snow so I may give it a try out in earnest sometime.
