Hiking saw from progressive means do it yourself
Good time, comrades!
I offer you your reflections and experiments on the sawing of a tree.
Of all those who have involved in my life in my life, I made a persistent belief - I drank a traveler in the forest (tourist, mushroom, hunter) is not needed. One exception - to Lady.
All other need for a harness of the tree trunk is not relevant. The traveler does not need to perform construction work, the roll of the forest, the harvesting of firewood in commodity volumes. All the work on the arrangement of the parking lot is successfully performed by a knife and an ax (it is an ax, and not those "Hutsul Sokiram", in which many of our comrades turn their tool).
Of course, if the purpose of the hike is to perform tasks that require a specific tool - the tool will have to drag. But now there is a conversation about the very forest pedestrian (tourist / mushroom / hunter), which all luggage drags on himself, and necessarily has matches-knife-ax (IR).
Why can he need to be in the forest saw? According to my observations, the barrel with a diameter of up to 100 mm is easier to cut down (an ax with it according to any), but more than 100 - easier to fill, faster and less energy intensively. This remark refers to places with a predominance of coniferous and soft hardwood. Oak, Beech, Grab and other acacias require a drink right away, but I do not go there.
Peregi, Napnik, not large firewood is easier to extort. From the "large firewood" it seems to me only the pair of login for nodium.
I think the diameter is optimal to 150-200 mm. With a length of 1.5-2 m, one such a log (dry) will weigh ok. 30 kg and heating device will not undermine the fragile health of the traveler. The log of 30cm / 2m will weigh the OK.70 kg - a bit too much.
So, we have teaching on the "firing saw":

- the possibility of a routine crushing with a diameter of 20 cm (max. 30 cm);
- minimum weight (better negative);
- mode of use periodic, rare;
- There is a time to prepare for use (there is no need to sharply snatch and sawing);
- Location in the laying of baggage arbitrary (not a knife and not weapon).
Of those known to me, the types of saws (chain, disk, hacksaw, tapes) I chose a ribbon-in-law, as the most simple.
Frequently used "hacksaw" has a significant weight (thicker and durable knife, massive handle) due to its design. Popular pocket saws are unacceptable to handmade propyl (up to 6 mm) and relatively with ribbon to be larger than weight.
Basic saw requires a saw blade, fastening the canvas and lace. Everything else is in place in 5 minutes.
The length of the saw blade should exceed the diameter of the log (the greater - the better, it will be more convenient to cut) and in our case, the web is a length of 300 mm (similar to the common metal canvas).
Two pieces of mounting punctuate and two M5 screws with nuts, saw blade - and the whole kit for a saw.
Making frame and assembly saws occupied approx. 10 minutes. As a screed used a lace from the wives jackets. Overall sizes saw ok. 30x30 cm, the maximum depth was cutting to 15 cm. In principle, you can also write a log to 30 cm - in a circle.
Sawing the trunk with a diameter of 13-14 cm. Two cuts for 5 minutes each (though one handle saws, had to change). I would finish this matter half an hour exactly, and my forces would have left without a balance.
The saw disassembled, sticks - to the fire, the canvas - in the backpack.
The first experience made changes in TTX tool:

1. The saw should be transverse (tooth shape is an equilateral triangle, double-sided sharpening). Such a saw cannot be cut differently, as the cross - so it is not necessary. In addition, such a saw is both stroke (and there, and back) workers;
2. The length of the saw 300 mm is obviously not sufficient. Maximum amplitude
Drying (comfortable handwheel) is not more than 60 cm. The most convenient I consider the length of the saw 40-45 cm (the lover work with his hands at home can check the height of the toaster on which it scares the plinth, without damaging the parquet). For laying in a backpack 40 cm - itself. So - Length is 400 mm;
3. Divorce of the teeth saw should be sufficient. And the wood is not too dry in the forest, and the trunk strives to clamp in the propylene during the provisions of the trunk. The total divorce (the width of the propyl) should be 2-3 thickness of the canvas. Better more, but it will be harder to cut - a larger volume of wood will have to "unzip";
4. At least one diagonal in the saw frame is necessary. For example, another lace connecting the top of the front handle with a middle (or opposite end) struts. So that it worked for tensile at the main working panel (from myself).
I fought a new saw to the summer fought - I bought the cheapest hacksaw, removed the handle, cut off the saw part of the width of approx 30 mm, brightened at the ends and put it in the laying.
Collection of saws occupied 10-15 minutes, diagonal was added.
The dimensions of the frame OK 45x45 cm, the length of the canvas OK.45 cm, the depth of the cut 20-25 cm. The saw blade from the first experience next to comparison.
Sawed with a diameter of 20-25 cm. One propyl occupied approx. 5 minutes. It is quite convenient to work, the main move - on yourself (get used to fast)

Comments, based on the results of work:
1. The thickness of the sticks used for the frame should be 3-4 cm. And the strength is sufficient, and keep more convenient;
2. The perfolred should be replaced by a wide band (for example, from galvanized) - the canvas twisted on the loop of the narrow punched.
Thus, I can read the fully formed hiking forest toolkit - Topor, MPL (folding), canvas saw.
Folding knife with a tree filling in my forest always with me.
