Introduction: 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

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.  
So.
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.  

Sincerely
Krešimir Pregernik

Step 9: 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.

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

    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:(

    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.

    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?

    It took me a while but I found it again: www.themule.com .

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

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

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

    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?

    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

    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.

    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.
