Pulka
« on: 16. 02. 2009, 10:07:12 PM »
I've made at pulka for a wintertrip. I used instructions from another site but made some, as I see, enhancements. I haven't tested it yet but I will do some field testing before the trip.





Here's a link to the pulka:

and the original plans:

The instructions are in Swedish but the pictures should speak for themselves. I will update the post as soon as I have tested the pulka

Then you wonder, what parts on the pulka are from shelby? The buckles of course! ;)

Looks like a good version. The reinforcing tubes attached with cable ties seems to be simple construction.

Here's some other links to pulk projects using cheap childrens pulks:

I've seen those types of pulkas and they seem to be good in the way you can get a low point of gravity and the big volume they have. I bought mine at a local toy store and this was the best suited pulka they had.

I've now done a field test. It works really well on packed snow but when in to deep powder (I tried with 40cm) it pushed snow in front of it instead of climbing up on top of it, though not that much. Could maybe be solved by adding some sort of plate in plastic in the front of the pulka. Just make sure to pack all of the weight long way back in the pulka and it will be fine.

It's quite easy to climb with and takes on the downhill very well. Even with some heavy turns, it just skids a little bit and then continues to go straight. It fits nicely in the ski tracks and doesn't destroy them so sports skiers will be happy. When going in prepared ski tracks, it goes like a train, on rails!

I remembered to bring my camera but the batteries were empty. I was planning on documenting the characteristics of the pulka, but you'll have to take my word instead. The next time I go out skiing with the pulka I will bring the camera and fresh batteries too.

I forgot to reply after the trip was done.

This pulka would be great if you're planning on skipping backpack and pack in a pulka instead. The big problem is that it can't handle weight very well. I would say maximum 15kg. I loaded it with nearly 30kg and it was very hard to control it downhill then. As long as the line wasn't totally stretched it would skid, but instead of continueing to go straight it flips and starts to roll. So I had to focus on keeping the line fully stretched when going downhill. The snow-pushing behaviour also got a lot worse, but it works if you try to put thge heavy stuff as much to the rear as possible.

As long as you keep the weight down it will work fine though.

You had similar experiences from light weight pulka as I and others have. It's good when you're not hauling a lot of gear and/or when you necessarily need the possibility to get all the stuff on to your back.
On longer hauls with heavier loads a stiffer and more robust pulk is needed.

Oerthex makes a nice plastic pulka with a flat bottom.
