Whiteburn's Wanderings

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

MLD Duomid A Frame

In a previous post, Duomid Pole Jacks, I’d been experimenting with an ‘A’ frame setup for the MLD Duomid using 12” jacks & lashing the handles together; it worked fairly well & produced a very stable setup for blowy conditions but I wasn’t totally happy with it as it was a bit too fiddly.

The inspiration for a ‘new & improved’ version came from a bit of internet trawling, including Robin’s MYOG ‘A’ Frame.  Well I’m all for keeping it simple so I added some plastic tube to join the original pole jacks & form the apex & then bent it at the appropriate point.

Tried it out yesterday for the first time, the result was better than anticipated, even in a blustery 25mph wind without the side guys the Duomid was rock solid.

As well as significantly improving stability the A frame opens up a lot of space.

With my BD poles, which extend to 140cm, I found that the Mark #1 was a bit longer than necessary. I found the effective pole length needed (apex to handle) was 165cm  (65”), so cut the aluminium tubes down a little, the final weight was 82g.

The aluminium tubing I used is 15.9mm dia * 0.9mm wall tubing (5/8” * 20g) ~18cm long (7”), the pole tip fits 3 – 4cm into the same plastic inserts (silicone cartridge nozzles) I used for the jacks.

The plastic pipe is 20mm HDPE water pipe, 20cm (8”) long, the wall thickness is a little over 2mm so it needs softening with a hot air gun to get it to fit over the aluminium tube (when cooled it’s a very firm fit), I pushed over about 5cm (2”).  When bent the pipe does flatten/ kink but the resultant ‘point’ is still nicely rounded.

& it fits neatly into the apex.

The BD poles also come with a nice little clip that neatly holds the ends together for packing.

I can’t see me using this set up much in the summer or on long trips where I’m pruning weight as at 82g it’s a whole 60g heavier than my simple pole joiner but it’ll definitely see use in the wilder months.

    Hi Paul – really interesting idea, would an A-frame / inverted V work with a Trailstar? I love the interior space of the TS but would like to make it more livable when with my partner, as we sometimes use a double quilt which doesn’t really work with the central pole.
    Thanks!

      Should be no problems with the TS though you’d need to experiment with the pole length.
