Introduction: KP Solowheel

Picture of KP Solowheel

Hellou, all! 
as a hiker, I found that my backpack, as day passed, become heavier and heavier. And also another point - i like to spend not only one day on top, I want to overnight and wait sunset as well  Summary, I have to carry about 15 to 20 kg, and well, it is difficult.
Then come to me a spark!
Hey, what if I take a wheel and split weight?
I collect all info about such idea and made a triangle from bamboo sticks,(natural material) insert a wheel and start to test.
It was perfect regarding weight, maneuverability, dissembling, perfect strong for 15 kg weight and extreme cheap. But. 

On rocks he bounced. When you come in rhythmical walk, weight start to bounce. Bamboo was to lissome/willowy. 

Back to paper and  here follows the construction of my KP solowheel II carriage, for hiking purposes. 

Step 1: KP Solowheel II

Picture of KP Solowheel II

Idea was to not carry a normal backpack (cca 2kg empty) on such carriage ... KP solowheel carriage has to be backpack itself as well. It has to be made from wood and in a form which I like. Volume about 50 liters net, upgrade to 80 l.  
First i took a cheap construction board, and cut this to make a mold. I want to have a box made from linear glued beech veneer. Veneer shall be 1.5- 2 mm thick  in tapes 130 x 1000 mm in three layers, unidirectional rings to get proper strength. So I made a mold for bending veneer. To make sides of my boxes.

Step 2: KP Solowheel II

I insert in mold a iron tubes to accommodate fasteners better. PVC glue is applied on each side of veneer. I use pick tape to temporally set veneer in a three layers, watching to turn  veneer side opposite to each other because of bending. Then using a wood board as a base, start to pres veneer, bending it in form.

Step 3: KP Solowheel II

I also needed straight elements for sides and connection elements, so I took three veneers and glued them together. Sanding after gluing was also necessary.  Then I cut out joints using electric small saw and old fashion tinny hand saw. Gluing parts together was successful. 

Step 4: KP Solowheel II

On joints I use as reinforcement tooth sticks and barbecue sticks custom made from bamboo as wooden nails. Each was pressed in drilled hole filled with glue.  Also on long joints i made a wooden wedge diagonally. Of course, also glued. To determine form of bottom on upper and lower part, simply  put glued sides on a plywood  and draw the lines with over +/-5 mm.

Step 5: KP Solowheel II

As time go, i start to assemble my idea. Holes for wheel and how it shall look like. Wooden nails made from bamboo barbecue sticks. Bottom cut out and glued on sides and nailed with wooden nails.  Parts together and then I use piano hinge to connect upper and lower part-box together, which allow carriage to be fold  to have possibility for chair  function as well. Folded completely allow me to carry this solo wheel carrier on a back as a normal backpack, --- only in extreme situations. Which shall never occur. I hope. Then I reinforce the hands ... and  voila.  KP solowheel was merged up.

Step 6: KP Solowheel II

I found later on,  that some reinforcements has to be made , specially on the curved wedges of lower box, so I ad two strip veneer on each side. On the end I add a seat for chair when KP solowheel shell be folded on half. Also reinforcement are made on the wheel fork -- for every case. 

Step 7: KP Solowheel II

I put a rope with gum around the sides on bottom part to serve as hook points and also the same hooks on the gum-rope to fasten all things under KP  solowheel cover.  Then I take a pictures of a KP solowheel carriage with rain cover on.

Step 8: KP Solowheel II

Plenty, after testing and trying and use in different situations, remakes-rectifying adjustments are made. Not shown on this pictures.
Now I use a plastic, air-tube  14" wheel, made for children bicycle. It is good to reduce bouncing and climb up and down over bigger rocks.
I have a strong belt over my hips, and on each side he have a simple hinge, to accommodate both KP solowheel hands, It is easy to clip it in and out this hands and free yourself from carriage. You can invent your way to do this. 
Well. I have now my solowhell and I took him on my few days hiking days. I can put about 60 liters of equipment. It can easy carry 10 liter of water.  For 6 days trip all load was about 26 kg.  60-70% on wheel. It make difference.

This suit for me.

Step 9: Hiking Pole

Picture of Hiking Pole

I took a bamboo stick about 25mm dia and scrap all outside enamel layer and rounded knots.  Then took a burner and made carbon mosaic on stick.  After I put on parquet lack in red color.  Top was made from walnut, - under I add a sponge to protect hand from constant bouncing/hitting.  A walnut handle is made from two pcs glued around bamboo stick  and filed to convenient  form. On bottom is adequate aluminium tube, with inserted steel pin. Enclosed *.pdf  is a sketch about dimensions of my pole (which is also a central pole in my KP tent)

GOOD work man! I must say I've been combing thru forums and websites etc. just knowing that someone also had the idea to make one of these. I myself will be delving into a creation much like yours. The idea of lighter cheaper construction materials is intriguing yet I'm hoping to build one to handle at least 100-150 lb's. My concept demands a bit more weight so I best continue my research. Hey once again Nice job.

Bravo! KresimirPregernik I now have more ideas of my own to think about thanks to your instructable many many thanks.

mkslocomb (author)2014-10-01

I love your work. Very beautiful. Would you please provide me some info about your tent? It looks cool, too.

Please do contact me on kresimir,

i hope i can find some place having so many trees there

What a great idea. Unfortunate that a wheeled device is not allowed in US Forests unless you are disabled:(

Johenix (author)2013-08-11

Do a Google on M.U.L.E. Someone has already pattented it and the U.S. military is looking at it as a way Special Forces (especially medics) can carry more. One man used such a device to carry his water supply for a hike across Death Valley, California.

ldmorgan (author)Johenix2013-08-16

Couldn't find M.U.L.E on Google--or rather, found 32,300,000 hits, and no way to narrow them down. Any additional info on that?

Sorry to leave you hanging like that. I broke it by Google-ing "Death Valley Mule Backpack.

AMDHamm (author)2013-08-13

Nice indeed. Practical and useful. Any chance on an Instructable for that hiking staff?

Please, take a look in step 9.

Now i understand. Yes i made this hiking stuff myself from a bamboo stick. I shall post some pictures about it.

Please, explain your question?

kouker (author)KresimirPregernik2013-08-27

That's about your intriguing looking hiking staff (visible on several photos). I think you are using it as a tent pole too. Did you make it yourself? AMDHamm is asking for a chance of another Instructable how to make one? I'm joining him in that: could you?

AMDHamm (author)2013-08-28

Indeed I mean the hiking staff (red pole). It is very interesting and I wondered if you made it yourself. If so, could you explain how in an instructable? Good hiking staves are difficult to find.

Very nice craftsmanship great job enjoy your hiking

jboseman (author)2013-08-14

This was very interesting to read, I have been on many trips long backpacking trips with people from 11-60 over various terrains(blue ridge mountains SC,NC,TN) and have seen people struggle with heavy packs and I think your really on to something that could allow those who can't carry the weight required for long trips. I only worry about the ability for it to withstand the trips, as in the terrain, and weather, the terrain being the most concerning, I pictured some steep and rough paths I have faced and thought how I would go though those situations with these and find it hard to pass though. I do however believe this could allow many to extend their travel range and comfort level while outdoors, also you showed amazing craftsmen ship with this build and it's a great product congrats

Over rough paths, steep rocks, you can still menage that ... put all as backpack when is folded on back... if is to heavy, split package into two parts an backpack it over such part of your trail in few passages... Klondike,,, gold fiber ... people carry over one ton own equipment in sequences of one mile 80 kg backpack.. and return for new backpack and so on... Jack London wrote.

I did the Camino de Santiago using a suitcase that turns into cart.

wobbler (author)2013-08-15

Excellent design! As I get older my packs get heavier despite them getting lighter! I like the potential of this idea but I like the idea of taking the load even further back over the wheel to lower the weight on the hips even more. I'm thinking of making something similar but using a normal plastic storage box as the container, both for ease of building and waterproofness.

Great food for thought though. Thanks.

Tracy_Marie (author)2013-08-13

This looks great in the end result, but much too complicated for little old me to make. (No woodshop either.Tiny appartment.) Oh well, little too ill to go hiking any more now days. Understood most of it though. Good job.

there are many commercial products available, of course buying something useful is not nearly the thrill of building something useful. But, that not withstanding perhaps the dixon roller bag would be your ticket:

Hey! Thanks!

Eh Lie Us! (author)2013-08-14

Good God, man. This is great!

DennisTheBald (author)2013-08-14

Awesome. The project, the instructable, the camping it gets used for... I salute you.

treii28 (author)2013-08-14

My dad used to use something like this as a deer cart. His design actually used two large bicycle wheels on a metal ladder frame that tapered in the back and the two wheels were angled where they were mounted on the back so they came together at their base just a few inches apart and worked kind of like a single wheel. That thing was great for hauling large weights over any number of obstacles such as logs or rocks.

boston7513 (author)2013-08-14

love this idea! construction is like violin or guitar. I have been thikn' about this type of Travoy for some time now, happy for you that you have made one!

jhuston1 (author)2013-08-13

genius and dedication in large doses...grats.

rof (author)2013-08-13

I read this through with interest until I got to the point of seeing how much this weighed - 6 kgs. I'm in the UK so I'm familiar with kgs, but also flip to pounds on occasions - that's 13.2lbs. I reckon on getting under that for the pack for a 2 night hike with tent, food, stove, sleeping bag and mat. There might be cases where this would work for me but not at that weight - and then what about river crossings, unpathed terrain and the likes ?

I like the instructions and might use the procedure for something else.

KresimirPregernik (author)rof2013-08-13

It is correct. Weight count. So go on and web just write ... mono wheel carriage.., and look on thousand ideas/performances. There are also You tube movies about river crossing...rough terrain...Ideas shall pop up for your version. It is always possible to put all this on back (or in parts) and carry on over difficult terrain. . ..

roofermann (author)2013-08-13

Very nice work, might make one myself with aluminum tube frame. Good job with the english too. From you name I'd guess eastern europe?

Thank you. State of origin Hrvatska, HR. (Croatia) EU. Capitol city Zagreb.

yopauly (author)2013-08-13

Reminds me of a Native American Travois, Modernized with a wheel and belt. Very nicely done! Gave me some ideas for a equipment hauler.

fixmystuff (author)2013-08-13

I love your solowheel. Add it on my list of "must make one" for next summer.

mnmama (author)2013-08-12

Good woodworking skills, and beautiful form. It looks like you could build a guitar. I like very much that you used wood fasteners except the hinge, it should keep the weight down, and looks nice. A couple of questions, have you been through heavy rains? I ask because I wonder if the joints stay solid when soaked. And lastly, how much does it weigh?

KresimirPregernik (author)mnmama2013-08-13

Well. All is protected with parquet varnish. Strong and durable. Glue is PVC waterproof. I think you can use this as boat for several days.. joke! I Think it can without problems withstand heavy rain and moisture, For such situation I use a tarp over..Total weight now with all improvemenst. seat. new wheel 14"...,is about 6 kg ...please you can use wood fasteners as you prefer... Sincerely

onemoroni1 (author)2013-08-13

I admire your ingenuity and creativity to improve the ease of camping. Basically you are towing a little trailer increasing capacity, reducing human work, increasing safety, and extending your range. A child's version would be effective too.

Kinnishian (author)2013-08-13

Wonderful! Thank you for the effort in sharing

simonbuysellit (author)2013-08-11

I know its totally against the grain of Instructables but I am wondering how many hours this took to build; it looks liked quite a few. Great work though.

I did not count hours ... it took me few month but if your have everything prepared and ready you can finish this in one week or two... depend of your skill and organisation. .

I didn't count hours but if you have everything prepared, in one wekk or evt.two it can be done. Depend of your organisations and skills.

One concern, especially on rocky terrain - is there a quick-release in case of an emergency (bear, etc)?

On the step 8 I add 5 pictures how it is hanged. Up or dawn in few seconds....

really nice work

dsgreene71 (author)2013-08-11

I commend you on the artisan craftsmanship, simply outstanding.
