The compact drill press is a must have in the home lab. If you are engaged in the design of various kinds of devices, then the acquisition of such a machine becomes a necessity. But you can always make a drilling machine with your own hands, it is much more interesting and cheaper. Moreover, this does not require scarce materials, this task is within the power of each of us. The main thing is to decide for what purposes you will use this device and what power is ultimately needed to operate the machine.
If you are a radio amateur, then it is quite possible to use a small-sized home-made drilling machine of low power to drill holes in printed circuit boards. It consists of an engine with a cartridge, which can be purchased from a specialized store. As a moving part, it is proposed to use the PZF frame. Such devices were designed for macro photography and are now no longer needed. If parts are available, make a small drilling machine of your ownhands will not be difficult and will not take much time. You will also need a small piece of organic glass or textolite.
Begin assembly. First, we cut out organic glass or textolite to size and fasten it to the base of the future machine.
Next, we prepare a hole for mounting the engine and install it. Now we organize the power supply of the electric motor, we assemble the circuit through a small switch. Motors of this power can be powered by DC voltage, which means you need a power supply. That's it, you have assembled a homemade compact drilling machine with your own hands. Before the first start, be sure to check the ohmic resistance of the motor and the integrity of the switch. Motor position adjustable
screw on the right.
If you want to assemble a more powerful do-it-yourself drilling machine, then to implement this idea you will need a powerful electric motor powered by a household mains. The ideal option in this case may be an electric drill, especially since there is no need to search for a drill chuck. The main difficulty will be the design of a mobile base. This problem is solved by using a lift table or vise base. Of course, you can also use a mobile support on which the drill is mounted, but in this case you will have to deal with the vibration that will definitely occur during the operation of the machine.
Fix the drill well on the vertical base withusing mounting brackets. It is best to use two or more mounts. Turn on the drill and at maximum speed under load, check its operation for vibration. Then mount the mobile horizontal base. To make a desktop drilling machine, it will not take much time, the main thing is to carefully assemble all the main parts of the product. Such a device is quite suitable for carpentry work, in addition, it can cope with drilling miniature holes for printed circuit boards or homemade crafts.
