To make a compact drill engraver with your own hands, you will need the most ordinary kitchen hand blender, which you can buy within 500 rubles. Also for this homemade product you will need a small cam cartridge and a key to it. They can be bought at Aliexpress for 300-400 rubles.
A home-made electric engraver, made on the basis of a kitchen blender, is useful in a home workshop for performing small-volume work requiring accuracy and high accuracy. For example, using this hand-held power tool, you can grind a workpiece, drill a hole, cut metal, etc.
The main stages of work
First you need to disassemble the blender body. We remove the factory nozzle, and cut off part of the body. Then we turn on the device, and with the help of a flat file for metal, we grind the motor shaft to the required diameter.
After processing the file of the motor shaft, we assemble the blender body back. Then we fix the nozzle under the cam cartridge for the engraver on the shaft. After that, we install the cartridge itself and fix it with screws.
Please note that the blender motor rotates the shaft to the left side, so the drills should also be “left”. Details on how to make a compact engraver from a kitchen blender with your own hands can be found in the video on our website. What do you think about this homemade product?
