Reciprocating saw from the drill - it is possible!

Imagine that you need to saw off a wooden block, and there are no hacksaws at hand. Favorite jigsaw at another site or even broken, and the workflow does not tolerate delay. The situation is familiar to many, is not it? Most masters know how expensive tools are at the right time. The work is boiling, there is no procrastination, everyone is happy. Worse, when it is not, and there is simply nothing to replace it with.
Home-made, considered today deserves attention, if only because it really helps to solve the problem of cutting with a conventional drill or a screwdriver. It is acceptable to make it at home with your own hands. And this is not some one-time fixture. This is a full-fledged technical tool-nozzle, which expands the possibilities of the main electrical device, intended as it seemed to us earlier, only for drilling and tightening screws. With it, you can actually cut a bar or even a board with a regular blade for a hacksaw for metal and turn an ordinary drill into a saber saw. Let's see how this can be done.

The principle of the saw


In fact, the torque of the drill does not go anywhere. It is only converted by the similarity of friction gears into reciprocating movements due to a crooked bearing. Its body slides between two small bearings, mounted vertically on a small metal square. It is this element that drives the canvas, tightened at its end in a special clip. The nozzle is mounted on the shaft, machined for sufficient diameter chambered drill or screwdriver.

Let's make a reservation right away that such an adaptation is not collected from improvised means. Most of it is quite accurately calibrated in size, machined on turning and milling machines. However, if you doubt the capabilities of your workshop, they can always be made to order.
Before starting work, it is worth making a drawing of this assembly, having calculated the dimensions of each element and align them proportionally. Our device is made entirely of metal, and therefore the vice at this time - a must tool.

We make a shaft with a bearing


This element requires a metal rod.Its cross section should be the same if possible, so it is best if it is pierced on a lathe.

We clamp it in a vice, and approximately in the middle with a file we grind off a slanting groove as in the photo.

We turn over the rod with the opposite side, and make a mirror groove leaving a thickness of only 2-3mm to accommodate the bearing.

We put the bearing on the shaft seat, bored out with a file. We need the most ordinary bearing - ball, single row, open type. The bore hole, as well as the diameter of the outer ring, will have to be selected empirically.

To fix the bearing on the shaft will help special clips. We make them from the pieces of the tube, densely pushed onto the shaft. Cut these segments need exactly the angle of the bearing. For clamping on the shaft, these tubes must be equipped with a hole with a screw for a small hexagon of the type of stop for drills.

Fix these clamps closely pressing them the bearing housing so that the walls touch only the inner ring of the bearing.

We take four washers of a suitable diameter, and we set them on a pair of each side of the shaft.This will help reduce the friction of the shaft clips against the side supports of our nozzle during operation. Shaft bearing ready!

We equip the case of our device


Surely everyone understands that the shaft itself will not work separately. He needs stops on which he will hold and relative to which he will move. They should be the same as in the photo - two squares with holes for free running of the shaft from the side of the planes, and mounting holes with threaded bolts from the side of the ribs. This construction is going to like this (photo).

A small plate with four through holes at the edges covers the structure, and fasten it to the bolts. This will be the first case cover.

At this stage, our nozzle should look like this (photo)

On the opposite side we place two squares with mounting holes for the bolts. They must be of such a size that the third square, which will be placed between them, can move freely relative to them.

The middle square needs to be prepared. On it we place two small bearings on the screws. They will slide along the main large bearing mounted on the shaft.

Cover the squares with a cover similar to the first one and pull it onto the screws. The nozzle is almost ready. It is possible to trace how the shaft with the bearing moves, pulling the middle square back and forth.

We make a tip for saber saw


In order to fasten the hacksaw blade, an adapter-clamp is needed. The tip proposed by the author has an end groove of square section. From the side of the planes are placed clamping bolts for the allen key. With a tight clamp, they are flush with the plane of the tip.

The nozzle - "saber saw" for a drill is ready. It is convenient and safe to hold in your hands, and it takes up very little space. Such a tool is really worth making for your workshop,Because he can help out at the right time with sawing wood. It remains only to try it in action and make sure of the wide possibilities of your instrument!
