How to make a pantograph for a frezer with your own hands

When milling used copiers, ie, pantographs with high cost. You can assemble a pantograph for the router with your own hands.

Milling on a special copying device.

Manufacturing pantograph

The milling cutter, equipped with a pantograph, allows in the process to perform the repetition of parallel lines of the workpiece. This procedure facilitates the manufacture of shaped parts, various ornaments and patterns. In addition, using a pantograph, you can perform various inscriptions on metal and wooden plates.

A homemade pantograph is not difficult to do, for this you only need 4 levers. Three such levers should be long and one short. In addition, they will need to make a few holes to mount the axles.

Milling on the copier.

The axles will be used to install the mechanism and mount the rod. The axial mechanism is a pin, at the end of which there is a cap. The copy part should resemble the compass element in which the slate is attached. Such a core part can be made from the tip of a plastic needle. Such a tip will gently slide in the process of work and will not spoil the original part.

You will also need an axis on which the entire mechanical part of the device will be supported. It should be fitted with a heel that serves as a stop. The last or extreme guide will serve as fasteners for the whole structure with the help of a special boss.

Such a boss should be made of aluminum cylinder. In its lower part you need to fasten 3 stingers, which can be made from small furniture nails. With the help of such studs, the base will be fixed on the treated plate.

Completion of work

The next step is to build a copier for the router. To do this, prepare the following components:

• 4 lines;
• 8 brass bushings.

Rulers should be made of plexiglass or plastic, their thickness - 4-5 mm. Plexiglass can also be used as a material for making rulers. Next, we mark these linear parts. This process should be approached very carefully, since the slightest error in size can lead to a malfunctioning of the pantograph.

Holes are drilled on the applied markings. At the same time their coaxiality should be observed. To achieve this, you need to add all the lines together and at the same time drill holes in them.

Then you need to insert brass bushings into the prepared holes. When installing them, a small amount of tightness should be observed: this will help the sleeves to stick more tightly in the rulers. In order to fix the axial parts in the sleeves, you need to make special clips. They can be made of steel hardened wire, the diameter of which should be 1-1.5 mm.

Then build the boss. In its lower part, blind holes are made that can be pierced with a core. Nails must be installed so that they protrude from the body of the boss 2-3 mm.

Having prepared all the necessary parts of the pantograph, they are assembled.

During this process, you need to ensure that all moving parts have a smooth and easy course.

In this case, all prepared holes should be marked. According to this marking, you can scale the produced copy of the part.
