What is required for the manufacture

Reciprocating saw from grinder

To make an electric saw you will need:

wood saw
a small piece of pipe 1.5 inches
bearing – inner diameter approx. 22 mm
metal sheet 2 mm
nut M8
bolts and nuts M6
reinforced washers M14

Saw elements

You will also need:

welding inverter
Bulgarian
vise
drilling machine or drill

Making an electric saw

Homemade electric hacksaw from a grinder

When working with a grinder, torque is used. We need progressive movements for a hacksaw. We will transform the rotation with the help of an eccentric.

Step number 1 - making an eccentric

Making an eccentric

This step will not cause problems.

We install a reinforced washer on the grinder spindle and put a bearing on top of it.

The center of rotation of the bearing will be displaced with a bolt. We note the excess.

Having sawed off the bolt, we place its shortened rod inside the bearing.

We lay a second reinforced washer on top and tighten it with an M8 nut;

The eccentric is ready. You can move on to the next step.

Step number 2 - we make a blank for attaching the nozzle

Fastening preparation

We will make it from a steel pipe.

We end the edge of the pipe on sandpaper.

We measure the distance to the lower level of the bearing.

Draw with a caliper.

Duplicate the markup with a marker.

We cut off according to the markings with a grinder.

Don't forget about personal protective equipment.

Step number 3 - make the mount

Nozzle holder

At this stage, the workpiece from the pipe will need to be cut in half.

We measure the length of the seat for attaching the nozzle.

Using a compass, draw a transverse marking.

We circle it with a marker and make markings for the cut, which is needed to fix the mount on the grinder.

We make a cut on the markup, incl. transverse.

We weld two bolts on the fixing propylene ring to fix the mount.

We clean up the weld.

We put the mount on the grinder, and fix it.

Step number 4 - making a body for a hacksaw

Hull preparation

The body will consist of 2 steel plates. Their dimensions are arbitrary, but should not be less than 2 diameters of the bearing used.

Cut off the plates.

We find their center and mark it.

We specify the outer diameter of the bearing and divide it in half on the caliper.

From the center of the plates we make control points with the help of a rod, apply the bearing and outline it.

We drill holes on a drilling machine.

Holes in the plates can be cut out. To do this, use a drill with small drills and a chisel. The geometry is adjusted with a round file.

Step number 5 - preparing the hacksaw blade

Preparing the woodwork

The markup is carried out in arbitrary sizes.

We remove the handle from the saw for wood.

We determine the place of contact of the hacksaw blade with the bearing. We mark the center.

Using a compass, we make the primary marking for the bearing - 3-4 points from the center.

We attach the bearing and circle it with a marker.

We form a hole according to the markup.

The resulting hole must be flared along the vertical level of the saw blade.

The hole must be formed into an oval. The dimensions of its diameters are approximately 1 to 1.3. To accurately determine the shape of the hole, you need to try on the canvas in place.

Step number 6 - assembly of the saw body

We form a bolted connection on the nozzle body

At this stage, you need to weld the cuff (fastening) to one of the metal plates and form holes for fasteners.

We fix the workpiece in a vice, apply fasteners and weld it to the plate. The bolts welded to the ring must be at the top.

We mark 4 holes for bolting in each plate.

We drill.

Let's move on to the next step.

Step number 7 - install the hacksaw blade

Installing a canvas on wood

According to the body plates, we make markings in the hacksaw blade.

Drilling.

For sawing, you need a hacksaw blade move, so the holes need to be bored along the saw by 1-1.5 cm, this must be done observing symmetry.

Periodically check the sufficiency of the holes for the stroke by scrolling the eccentric.

Step 8 - final assembly

final assembly

After you have made sure that the rotation of the eccentric is stable, you can finally assemble the attachment for the grinder. Do this with two nuts for each hole.

For appearance, the product can be painted. Before assembly, the inner parts of the plate must be thickly greased with lithol.

Testing an electric saw from a grinder

Nozzle works

The tests were successful. This saw is surprisingly good at sawing small logs in a couple of minutes.
