Jigsaw machine from the compressor from the refrigerator (with oil bath)



I welcome all fans to craft, I propose to consider instructions for the manufacture of a jigsaw machine do it yourself. As a basis, the author adapted the motor from the compressor of the refrigerator, and in order for the motor to serve for a long time, the author even figured out how to make an oil bath. The machine turned out to be quite productive, the author puts the blade for jigsaw and easily cuts plywood, boards and more. The car turned out to be quiet, durable and quite comfortable. If you are interested in the project, I propose to study it in more detail!

Materials and tools used by the author:

Material List:
- compressor from the refrigerator;
- plexiglass;
- profile pipes;
- Sheet steel;
- long nuts and threaded rod;
- bearings;
- paint;
- car engine oil;
- caps for pipes

Tool List:
- Bulgarian;
- welding machine;
- drill;
- vise;
- files;
- a hacksaw for metal.

Manufacturing process homemade:

Step one. Motor preparation
First of all, we arm ourselves with a grinder and carefully cut the compressor housing. Inside, in an oil bath there is an electric motor with a compressor. Carefully drain the oil so as not to spill. We cut off the extra tubes, and also remove the valve from the compressor, as a result, we will have access to the piston. Note that dirt will reduce the life of the motor, so we try not to litter much when disassembling and assembling.




Step Two Frame
We assemble the frame for the machine, there is nothing complicated, we use profile pipes as the material, and you can install a sheet of steel at the bottom. The essence of the design is that it can then be glued to plexiglass and thereby make an oil bath for the engine. We also install the stand in the form of the letter "G", there will be an emphasis for the cutting blade. All welds must be thoroughly cleaned, the pipes must also not be dirty or in rust.




Step Three Piston Mounts
We need to make fasteners on the piston, in which we wrap a bolt or a threaded rod. As such fasteners, the author came up with a long steel nut to be welded to the piston. It is necessary to cook carefully so as not to damage the cylinder and not litter with slag.

Step Four Plugs and motor mount
We open all ends of profile pipes with plastic plugs. The motor will need to be securely fixed to the base, fasteners are made from pieces of a profile pipe, corner or similar material.



Step Five Emphasis
Under the cutting blade of the jigsaw you need to emphasize, as the basis, the author used a corner. We drill holes and thread the screws. The author used three bearings as stops; we fasten the bearings with screws. The emphasis should be adjustable, we make a slot hole that will allow to move the emphasis.

When everything is ready, the frame and other steel parts can be painted.











Step Six Cloth clip
We make a clip for the canvas, the author took a bolt, cut off the hat, and in the rod made a cut along the hacksaw. The cutting blade for the jigsaw will be inserted into the resulting slot. To tighten the manufactured "cartridge", tighten a long nut, and it compresses the canvas. The result is a simple and sturdy construction. We wrap the other end of the threaded rod in a nut welded to the piston.





Seventh step. Assembly and testing
We assemble the machine, it remains for us to stick plexiglass, the motor should be in an oil bath. It is important to understand that everything must be done hermetically so that the oil does not leak out. Silicone is suitable as a sealant, and you can screw plexiglass with screws. The author used a simpler option and applied hot glue.










Do not forget to remove the cable from the motor, as well as install the capacitor and other parts in a protected place. When everything is ready, pour motor oil for cars into the oil bath. Oil needs to be poured so much that the crankshaft can catch it, it will already scatter oil on the cylinder and other components.






That's it, put the countertop and you can test the machine. Everything works perfectly, the machine easily cuts plywood and a rather thick board. Inside the case, you can see how the motor is lubricated. All that remains is the problem of debris that will fall into the housing and contaminate the oil.
The project is completed on this, I hope you liked the homemade work, and you found useful thoughts for yourself. Good luck and creative inspiration, if you decide to repeat this. Do not forget to share your ideas and homemade things with us!

All dust and shavings will spill into the oil bath

as Kanevsky said ... xaxa
This will be a completely different machine.

I think the knife should not go with your teeth under the countertop and the gaps there should be minimal, even what type of "seal" to put, maybe even a fabric one.
But then the body of the knife without teeth will rise above the countertop and will not cut ... going over the countertop, you need to make a second countertop, which will be cut.
I read the article, watched the video of the original source and realized that the seemingly interesting homemade product was complete bullshit. At first
As such fasteners, the author came up with a long steel nut to be welded to the piston.
But the author did not share his experience on how to weld a steel nut to a cast iron piston. Secondly, sawdust is poured directly into the aquarium with oil, and it doesn’t matter that the direction of the saw’s teeth is upward (which is no longer a gut for such a machine, the video shows how the part rattles and goes “apart” from the table), the sawdust will still In oil. A masterpiece of engineering type
The author used a simpler option and applied hot glue.
It’s not worth commenting at all, although the author claims in the video that the machine was made not one-time.

And part of the sawdust will fall into the oil

Quietly rustling with slate, the roof rides slowly ...
Yeah, confused Dima. Everywhere in the article is a compressor from the refrigerator.
motor from the compressor of the washing machine
In what washing machine and why is there a compressor in it?
