Reciprocating saw blade

Sawing machine with reciprocating blade motion Greetings to all DIY lovers and those who just looked at the site in search of interesting ideas. Today I will present to your attention an option for making a saw machine. Perhaps, something similar is already on the Samodelka website. The author got the idea to make this machine when he came across an old rear hub from a VAZ 2109 car. In addition, a front brake disc was required. And then it all started. What happened in the end is worthy of attention, an excellent option that will come in handy in a workshop or in the country. The machine is designed for a standard blade, which means that it can always be replaced in the event of a breakdown. With all this, the design has a small size, which is also very important when installing in small rooms. The author selected all sizes for himself and thought over during the manufacturing process, but this does not mean that you cannot repeat. The design is not complicated, this can be seen from the photo, the author also gives some sizes of materials and parts, and demonstrates this in key moments. Home-made, of course, is laborious with many stages of work, therefore, the author omits some simple and understandable moments in order to save our time with you. In general, if you are interested in the idea, sit down more comfortably, study the article or watch the video (it is below), whoever is more comfortable, let's go !!!

Materials:

* rear hub from VAZ 2109 ,
* front brake disc, also VAZ,
* motor either from a washing machine, or an analogue,
* shaped tube 80×40 mm,
* shaped tube 60×40 mm,
* shaped tube 25×50,
* square 12×12 mm,
* bolts, washers, nuts,
* bearings,
* sheet (from the author on metal),
* paint for metal,
* sheet metal with a thickness of 2-2.5 mm.
* a piece of metal corner (for a stop).

Tools:

* marking tool ( square, ruler, marker, core),
* welding machine,
* grinder,
* vice,
* drill or screwdriver,
* file,
* magnetic squares for welding .

Step 1.

The author begins his work with the preparation of all the necessary details. The disc and the hub are cleaned of rust. Then he cuts the pipes and squares into the required dimensions. I will not list the sizes, they are all shown in the photo.

Step 2.

At this stage, the author takes a workpiece from a pipe 80×40 mm, 47 cm long, marks the opening on a wide wall in the middle. Then he clamps the part in a vice and with a grinder cuts a window under the lower part of the hub. Installs the hub without flange and disc, puts marks with a marker, as shown in the photo.

With these bolts, it fixes the hub inside the pipe and fixes the flange and disc to it. The first machine node is ready.

Step 3.

7 cm, marks them as shown in the photo.
First, it is drilled according to the marks, then it cuts out the excess with a grinder. The edges are processed with a file. The result is this detail. Bearings (8 pcs.), Washers, bolts, nuts and threaded rods are additionally selected for it.

To what happened, the author welds a piece of pipe 25×50 mm. Here's what he gets in the end. Just the same, the author omitted this moment, but I think everything is clear from the photo, and even more so from the video. Similarly, the author has collected another such detail. These are guides.

Step 4.

At this stage, the author goes to the square. The author arranges the blanks in the form of a rectangle, one by one. Then, to the long sides, in the middle, he puts pipe segments 50×25. After fitting, everything is welded using magnetic squares to maintain a perfectly even angle. After welding, all seams are processed with a grinder with a grinding wheel.

Step 5.

At this point, the author returns to the previously prepared node. Installs guides on it. The cruciform part made in the previous step is installed in them. It adjusts everything to the desired level. Then the guides are welded.

Step 6.

Then the author takes the bearing, installs it in an opening on the disk, puts a marker with a marker and drills a hole along it. Then he cuts a thread in this hole. Takes a bolt, four bearings and a washer. Gathers it all up and screw it into the threaded hole. This is the pendulum (reciprocating mechanism).

Step 7.

And so the mechanism is ready, now you need to make a rack for it. To do this, the author takes an axis, from which it is not known, maybe someone will guess, or you can pick up something similar. The author clamps this axis in a vice and cuts off a part of the desired length with a thread at the end. Then he picks up a large, narrow nut and welds to the cut. It turns out such a screw.

The length is selected experimentally, unfortunately, the author also omitted this point, but I think you can determine this value. Then the pipe is welded to the roller.

Step 8.

At this stage, the author welds the previously assembled mechanism to the rack. Everything is simple and clear here, I think no additional explanations are required.

Step 9.

And so, most of the machine is already assembled, but what kind of machine without a base. It was his manufacture that the author was engaged in at this stage. The author welded the frame from scraps of pipes, apparently those that remained after cutting the main parts. The size of the base is selected relative to the already finished, previously assembled unit.

Step 10.

As you already understood from the main photo at the beginning, the machine (or rather the working part) will be driven by a motor through a belt. The motor is there, but it needs to be fixed. To do this, the author cut out from sheet metal, about 6-8 mm thick, just such a detail, welded on it guides from a 10×10 mm bar.

I connected it with a belt with a disk, and in order to tighten it, you just need the grooves on the mounting plate through which it is bolted to the base.

Step 11.

Then the author made a handle, also from pipe scraps. I cut out such openings in her body.
Through a nut-insert I fixed the handle on the beam with a bolt.

Step 12.

By the size of the frame, the author cut out a plate from sheet metal with an allowance of about 1.5 cm on three sides. The author welded this plate to the frame from below.

Step 13.

Now it remains to prepare the fastening of the canvas itself, but where can we go without it. For this, the author made two such racks. Under one of them there is a movable clamp for tensioning.

Additionally, on the base, on the thumbscrews, the author fixed the stop from the corner. To make it easier to raise/lower the beam, I installed a shock absorber.

I connected a cord with a toggle switch to the engine. Then he tested the machine in action. He cuts wood with a bang, not surprisingly, the canvas is for metal. But the machine coped with the channel perfectly, the cut turned out to be perfectly flat.
