How to make a hand chain saw

These saws are very convenient to use during hiking trips - they take up very little space and cut perfectly. Buying a factory-made tool is not always possible, but there is an easy way to make it yourself.

What you need

The saw is made from a chainsaw chain; a piece of polymer sling 60–70 cm long and approximately 3–4 cm wide is used for the handles. The elements are fastened with M6 bolts with washers and nuts. The plastic is glued together with an iron through baking paper, the chain is disassembled using a small grinder and a punch.

Manufacturing process

Place the chain on a flat surface and find the connecting link. Using a cordless angle grinder or grinder, carefully cut off the head of the rivets connecting the chain links.

Place the chain on a vice and remove the axes of the connecting rivets with a punch, the chain will be disconnected.

Prepare two pieces of polymer sling, each about 30 cm long. Bend them in half; the size of the loops should ensure a comfortable hand position while working with the saw. Bend the ends 3-4 cm and fold them together. In this way, a reinforced unit for attaching the chain is prepared.

Place a piece of baking paper on a piece of board, one end of a folded sling on it, and again paper on top.Use an iron to heat the prepared area until the polymer melts and sticks together. Heat carefully, do not allow the plastic to completely melt - some types become brittle; when using a saw, the place where the chain is fixed cracks; the tool will have to be repaired in the field. Using this technology, process all four ends of the pieces of tape.

Using a punch, make holes for the bolts. They should be placed approximately in the middle of the prepared area at a distance of 2–3 cm from the end.

Attach a chain to the handles. First, place a bolt and washer in the hole, put the open chain link on it, then the other end of the handle and tighten the connection with a nut.

The hand chain saw is ready for use. Press down on the branch with your foot and try to cut it. If the chain is sharp, then harvesting firewood of the required length will require a minimum of physical effort and time.

Conclusion

The range of movements is small; for manual work, a chain length of 30–40 cm is sufficient; the handle can be made of a strong rope. This saw is more compact, takes up less space, and the cutting speed is the same. The factory length of the chain is enough for two devices.
