Introduction: Do It Yourself Adjustable Trekking Poles (for About $15)

This Instructable describes how to build a set of fairly light weight adjustable trekking poles. The inspiration for this project came from a short trip I took with a friend last year. He was using his REI poles and he had an extra pair that I could use. I had never used them before but i thought, "what could it hurt"? It turns out I loved using them. Especially when going down hill, and while crossing rivers. When we got back I though I would get a pair, that was until I saw the price tag. Poles range from $50(for crap) to more than $150 for nice ones. That was and still is out of my price range, especially in this economy. I did some research and found several plans for the do-it-yourself'ers out there, but I did not find anything that I really liked. I wanted them to be adjustable so they would be comfortable for all situations; up hill, down hill, ect. I tried to come up with a way of doing this for a while and it finally came to me, it has been done before, let's see how the pros do it. This also gives us a chance to recycle!

Step 1: Gather Materials

1. Aluminum Downhill Ski Poles, (Thrift store - $3.99)
2. Fiberglass Cross Country Ski Poles, (Thrift store - $4.99)
3. 18mm replacement "expanders" (Outdoor Equipment store - $4.25)
4. 2x 5" M8 bolts, (Hardware Store - $2.50)
5. Epoxy Putty (I already had this), (Hardware Store - $?)

The replacement "expanders" were the trick, I might still be scratching my head if I had not found these.

Step 2: Cutting the Poles to Size

The measurements in this step will be different for every one, since everyone will use different poles and will likely not all be 6'2" like myself. Thus I am not going to bother with that.

What you want to have is a top section that is able to telescope and collapse over the top section while leaving at minimum 6" between the end of the top section and the adjuster.

When you are on level ground the poles should be at a height so that your forearm is parallel with the ground. From there there should be enough sustainability to give adequate reach when descending typical trails.

The ones I build can be adjusted between 44" to 59". This wide range lets either my wife or I use them in all foreseeable situations.

Step 3: Preping the Bolts

The "expanders" work by having a threaded shaft with a point screw in to them (see pictures). To accomplish this I simply cut off the head of the bolts and ground them to a point.

As the pointed shaft is threaded in to the "expander" it forces the sides outward. When inserted in the upper section of the poles this will bind with the wall and be held in place with a surprising amount of force.

When grinding the point, take care not to damage the threads as the "expanders" are plastic and if the threads are damaged it can wear out the plastic quickly.

Also be sure to make the point quite steep. The steeper the point the more gradual the expansion for easier adjustment.

Step 4: "Gluing" the Bolts

Here I used Epoxy Putty. There is probably a hundred different ways to do this, but I like the stuff and what's more, I already had it in the garage.

If you use Epoxy Putty, just break off about and inch and work it in your hands until it is uniform in color, as this will insure the catalyst is properly integrated. Next, wrap the end of the bold and insert it in to the bottom section of the poles. Work it in as much as you can to take up the space between the bolt and the inside of the fiberglass pole, then smooth out the top and let it harden. I made it so the bolt was exposed by about 1.5"

Don't forget to mark the max length on the poles so they don't bend on you. Have fun!
That's it, you are done.

Step 5: Notes

Here are a couple suggestions I have if you plan on building a pair of these for yourself.

Hand Grips:
Look for hand grips that are comfortable for you. When you can find them look for a set that you can add adjustable wrist straps to. Addition of the wrist straps takes the strain off of your fingers for gripping the poles, after hours on the trail a death grip on poles can really hurt. If you have the wrist strap, all of the strain is transferred to the back of your wrist and a light grip is adequate for great stability.

Upper pole section:
Look for a pole that has plenty of length with none to very little taper near the top. This is for the "expander". There is a limited amount that the "expander" can expand, if there is too much taper in the pole the "expander" may not be able to grip tightly in all positions.

Expanders;
there are several sizes of "expanders" be sure to pick the size that is appropriate for your use. Too small and there will not be enough clamping force, too big and it will not fit in the tube.

Bolts:
this may sound like a big "duh!" but be sure to get the correct size and thread. I almost purchased the wrong thread because I thought the plastic was just tight. The bold should thread in with very little force and bottom out in the "expander"

I think this website is all about repurposing items. Building something is part of our enjoyment. I feel that you have missed the point entirely.

Whilst I also enjoy making things especially if it means I can save some money at the same time I cannot see myself spending time making something that I can buy for less when I can be spending time on other projects that either I could not afford to buy ready made or that is not available ready made I have never met any person who has more time than projects to fill it with. but I accept that there are people out there that may have more time than ideas to fill it with.

At the time this was written, adjustable poles were around $75, and I had very little money. So, I built these and shared the process.

OK Sorry I was just pointing out that they were available at a price that for some people made them not worth making your own I accept for some people they cannot obtain them at such a low price as it depends on where in the world you are, I have removed the original comment now.

I have to say your instructable is one of the better ones on this site with all the main points explained and photos of the whole process with where to buy from and at what price.

Regards Poppy Ann.

Yes, it's true. You did.

nice job, gonna give this a try

I bought a nice hiking stick with adjustable length with a nice grip and adjustable strap for only $15 at Dick's Sporting Goods

What the heck is a 2 x 5" M8 bolt??? I stuck a 3/8" bolt in the expander and it's working just fine!

2x = quantity of 2 5" = the length of the bolt i used M8 = a metric size "M8" (Leki is original a European company) I am not sure how well a 3/8" bolt will work. it may be a close fit, but you will likely ware out the threads in the expander. good luck

I'm in the process of making these for myself. A couple of suggestions- before the epoxy dries, insert the bolt with the expander on it into the top pole so the bolt will be properly aligned and straight, make sure there is no epoxy on the outside of the shaft! Also I found two light aluminum ski poles that slide inside each other, I feel safer without a fiberglass bottom section that could break easier. Great instructable, you just saved me at least $100 that I can put towards my sleeping bag! (Getting into ultralight backpacking at age 58.)

Can you make a hiking pole out of PVC pipe?

it may be possible? but PVC is heavy and very flexible, so the stability would likely suck unless the diameter were large, which in turn would make it heavier.

ski polls are all over thrift stores, they are cheep, and they are designed for a similar purpose. that is why i used them.

good luck

sad but true,. walmarts got ya beat,. 13.88 for a single pole or 20 for a set of 2.

I saw these, as well as the ones available at Fred Meyer. yes they are cheap but: 1 the weight is about twice what mine weigh 2 the Leki clamps in mine hold much more weight, and are replaceable if they ever where out. (try to do that with a wally world brand)

srohwer (author)2009-06-10

I think I've got it, but could you confirm? 1) Cut off fiberglass poles and use the bottoms 2) Install expanders on fiberglass poles 3) Cut off aluminum poles and slide over expander and fiberglass pole. 4) Twist and tighten. Thanks, and nice job. I'm headed to the thrift shop tomorrow!

that's it.

admanrocks (author)2009-06-10

Have you tried them out yet? and how much weight do they hold for you?

I have not taken them on the trail yet, but they can take my full weight. I will likely take them out this weekend. I'll let you know how they do.
