Elevator for a router: several DIY options. Do-it-yourself milling elevator Milling elevator lift eccentric rocker arm

Milling elevator, which Victor Traveller uses in his, as I understand it, end table. So to speak, the newest model. The milling cutter uses the same long-suffering interskol FM32.

The most interesting aspect of this lift is the ability to adjust the position of the router without bending over or crawling under the table. This is done with an imbus key directly from the countertop.

The entire block together with the router can be easily dismantled and replaced with a circular saw. Let's take a closer look at the structure of this lift.

The lift itself consists of two U-shaped halves that move relative to each other. One is fixedly fixed relative to the base of the router, the other is movable (it pushes the head of the router up)

They are connected to each other (that is, a bolt with a hexagon head and a pin of the appropriate diameter) using a pair of nuts (main and locking). In this case, the hexagon bolt remains on top, flush with the table surface. By means of a wide nut, rotation is transmitted to the pin, from which, respectively, onto the mortise nut in the lower half of the slide, which, due to rotation, is pulled up.

A lift for a router, which can be purchased in a serial version or made by hand, is a device that allows you to improve both the quality and accuracy of processing performed with hand-held power tools. The results of the latter strongly depend on how accurately and confidently the user manipulates such a device. In order to minimize the influence of the human factor on the results of processing performed with a manual milling cutter, special devices were developed.

Homemade elevator for a manual router, made of plywood and timber

One of them is a mechanized lifting device for milling power tools, which, in full accordance with its functionality, is called an elevator. As mentioned above, such a device can be purchased in a serial version, but it will not be cheap, so many home craftsmen successfully make it with their own hands.

Why is such a device needed?

A lift for a router, which ensures precise movement of a hand-held power tool mounted on it in a vertical plane, is necessary in many situations. Situations in which the quality and precision of processing of wood products are of no small importance include decorative finishing of furniture panels, making technological grooves and lugs on elements furniture designs. The quality of processing in such cases will not depend on the experience of the master performing it and the firmness of his hands, but only on the accuracy of the device settings and the degree of its stability.

Even a person with good physical fitness gets tired when working with a hand router, the weight of which can be 5 kg or even more. This directly affects the accuracy and quality of work. In addition, the precision of processing that a manual milling machine mounted on an elevator can provide cannot be achieved when manipulating a power tool manually.

The need to invent such a useful device as a lift for a router was led by the fact that the variety of types decorative finishing The production of wood products has expanded significantly, technological methods for processing this material have become more complex, and the requirements for the accuracy of its implementation have also increased. All of the above factors require that manual milling electrical equipment combine high mobility of its working body, as well as the accuracy of the movements it makes. It is these requirements that are fully met by a lift for a router, with the help of which the power tool in use quickly rises and lowers to the required height above the workbench, and is also held at a given level for the required amount of time.

The convenience of using a milling elevator also lies in the fact that it is not necessary to install a power tool on such a device each time. This contributes to both simplification production process, and increase its productivity.

On what principle does the lift for a router work?

In order to raise or lower a manual router using a router lift, you can use a crank, lever or any other lifting mechanism suitable design. Such functionality, which the lift for the router has, is ensured by:

quick and accurate setting of the dimensions of grooves and other relief elements cut out on the surface wooden blank;
Possibility of quickly replacing tools in the milling cutter chuck.

To summarize the options design the most used models of milling elevators, then the principle of operation of such a device can be described as follows:

A support plate for the router, which is made of a sheet of metal or textolite, is mounted on a work table or workbench.
Two racks arranged in parallel are fixed to the support plate.
The manual router itself is mounted on a special carriage, which has the ability to move freely up and down along the racks installed on the support plate.
The carriage with the milling power tool installed on it and the entire elevator move to the required distance due to the fact that they are acted upon by a special pushing device.

Let's consider the basic requirements that should be followed when planning to upgrade the router with your own hands using a lift.

The frame for placing the router and all other structural elements of such a device must have high rigidity. Compliance with this requirement will not only improve processing accuracy, but also make the user’s work safer.
The lifting system with which such a device is equipped must be designed in such a way that it can ensure not only quick removal and installation of the router used, but also prompt replacement milling heads on it.
The working stroke of the milling elevator should not be made too large; it is quite enough if the working head of the power tool moves within 50 mm. This is quite enough for high-quality execution most technological operations.
When developing drawings, it should be ensured that the working head of the power tool used can be rigidly fixed in a given spatial position.

What is needed to make a milling elevator

In order to make your own milling lift, you must prepare the following kit consumables, tools and technical devices:

directly the manual router itself, from which it is necessary to remove the handles;
electric drill;
standard car jack (if lifting mechanism the device will be of the jack type);
sheet of metal or textolite;
wooden blocks square section;
aluminum profile;
sheets of plywood and chipboard;
guides made of metal;
threaded rod;
screwdriver set various types and size, wrenches and pliers;
drills of various diameters;
bolts, screws, nuts and washers of various sizes;
epoxy glue;
square, ruler, measuring tape.

Possible design options for the device

Today, home craftsmen have developed many designs of milling elevators, but the most popular and, accordingly, worthy of attention are two options for manufacturing such a device:

a lift for a hand router, driven by a car jack;
device, structural elements which consists of a support disk, a threaded rod and a flywheel disk.

Option one. Elevator from a jack

The operating principle of a jack milling elevator is based on the fact that the working head of a manual router mounted on a support plate is raised and lowered by controlling the jack built into the structure.

A do-it-yourself jacking router is made as follows:

A box made of 15 mm plywood or chipboard is attached to the bottom of the desktop, which will simultaneously serve as a support device and protective casing for the entire device.
In the inner part of such a box, the dimensions of which should be pre-calculated, both a jack and a hand router connected to its moving part are placed. The jack, when placed in the box, is screwed with its sole to the underside of the support casing, and a manual router is connected through a special metal sole with its top part With inner surface workbench table tops. At the same time, in the tabletop it is carried out through hole, through which the working head of the milling cutter with the tool fixed in it should freely pass.
A sheet of textolite or metal of the appropriate size is used as a support plate for installing the router, which, under the influence of force from the jack, moves in the vertical direction along two fixed racks.

Option two. Threaded rod lift

The manufacturing diagram of the device using a support disk, a threaded rod and a flywheel is as follows:

A circle is cut out of a board 18–20 mm thick, which will act as a support platform for a hand router.
A hole with a diameter of 10 mm is drilled in the central part of the support disk, into which a threaded rod of the same diameter is inserted. The length of the pin, which is connected to the support platform using two nuts and washers, must be selected in such a way as to provide the router with a working stroke of at least 50 mm.
The lower part of the pin, passed through the plywood bottom, fixed between the legs of the work table, is connected to the disc flywheel. Keep in mind that the hole in the bottom through which the bottom of the stud will pass must have a flange nut built into it. It will ensure the operation of the lifting mechanism.

Using milling elevators in conjunction with mechanisms that will additionally provide lateral movement of power tools, you can make an even more functional device that will turn your hand-held equipment into a full-fledged 3D milling machine.

Option three. Chain drive elevator

Making this milling elevator will take much more time, but as a result you will get a clearly working system for raising and lowering the tool.

Every craftsman who works with wood knows how inconvenient it is and how many unnecessary actions have to be performed to set the desired cutter height when working with a hand router, or to replace one cutter with another. To do this, you even have to remove the router from the table.

In order to significantly facilitate this task, it was invented long ago special device, called a milling elevator, which is, in fact, the “third hand of the master”, which helps regulate this process.

Currently, there are a large number of different models of milling elevators on sale. The best elevators are made in the USA and are quite expensive.

Not long ago, in one of the woodworking magazines, the design of a homemade elevator designed for a hand router was shown. This design will allow you to quite accurately adjust the height of the cutter, and make it yourself for good master will not be difficult. Besides there is detailed photo With detailed description the entire process of producing such a model.

First of all, you need to make a disk 18 mm thick, on which the router will be attached. Now, using a Forstner drill with a diameter of 20 mm, we drill a recess with a depth of 13 mm in the center of the disk, then a through hole with a diameter of 10 mm.

We install an M10 threaded rod into the hole we drilled and secure it with two nuts and washers. Select the length of the stud so that the vertical stroke of the router is about 5 cm. Just above the middle of the stud we install a flywheel for adjustment; for fastening we use a nut with a washer and a flange nut. We will attach the flange nut to the stud using epoxy glue.

Finally, install the plywood bottom into the table, positioning it about 75mm from the bottom ends of the legs, insert the flange nut into it and screw the bottom end of the stud into it. Now, when the flywheel rotates, the entire structure will rise or fall relative to the flange nut fixed in the bottom. If you use a standard M10 stud with a thread pitch of 1.5 mm, when turning the wheel one turn, the amount of movement of the router will be 1.5 mm, half a turn - 0.75 mm, etc.

Residential complex Podkova

The Podkova residential complex is located in the Vsevolozhsk district. Its developer is “Russian Fairy Tale” together with “Arsenal-Real Estate” and “Polis Group”. Construction of this facility began in 2012. The complex will be built on the picturesque shore of the lake, just a couple of minutes walk from the Ocher River.

Accessories for hand routers

Lift for a router made from a clamp

If you regularly use a router mounted on a router table, you know how difficult it is to adjust and adjust the height of the bit in the router. There are milling elevators for lifting the router, but they are usually quite expensive. So I created a simple homemade router lift from available materials. This lift saves a ton of time and I find that all adjustments with a router are much easier to make effortlessly using a lift mounted under the router table.

To make the elevator I took steel pipe 3/4 in diameter? (nipple length will depend on the size of your router) then made a miter coupler and a second 3/4 nipple? connected to a flange (nipple length will also depend on the size of your router table) as shown in the drawing below.

Then I did wooden base to support the router. I drilled a 3/4? hole in the base. This hole allows the base to slide smoothly over the nipple. The clamp is screwed to the base and serves as an adjustment mechanism. I then installed the router lift under the router table (see photo).

To get maximum adjustment, be sure to set the router lift to its lowest position. The curved handle of the clamp makes it easy to adjust the router and move up and down the steel nipple. This makes it easy to adjust the router to any position you need.

Lift for a router from a spark plug key

The lift for the router is extremely important and useful device. It's fast and convenient way adjust the cutting height of the cutter.

Do-it-yourself elevator for a milling table: design and assembly

Correctly setting the cutting depth will not only create cutting accuracy, but will also simplify the adjustment of product joints.

I made the lift for the router from a regular spark plug wrench for a car and a nut of a suitable size. The nut must match the external size of the spark plug wrench, and the internal diameter of the nut must correspond to the size of the bolt used.

Using nylon or other soft material, drive the nut into bottom part key Handle on back side I made a spark plug wrench for ease of adjustment. A nylon retaining ring between the nut and the base of the router will help prevent spontaneous free rotation during operation.

This router lift can be used on various hand routers such as Hitachi, Festos, Mafells, Dewalt, as well as small Bosch models.

An essential requirement is that you need to consider the location of the bolt on the base of the hand router, its length and easy access during operation.

Note: The easiest way is to use a nut with a nylon insert inside the key.

Make a lift for the router yourself, or buy a ready-made one? Let's answer this question.

When using a manual router installed in a stationary table, two questions arise:

How to adjust the depth of immersion (extension) of a cutter.
How to quickly change replacement tips.

Unscrewing the tool from the plate every time is too troublesome. In addition, a statically mounted router works in the workpiece only at a fixed depth.

This problem is solved by installing a height-adjustable suspension on the router. And once you were able to make a full-fledged milling table, installing an elevator of your own design is not difficult at all. In addition, a self-made device is developed taking into account all the requirements of the master, even those that are not provided for by the factory device.

Why do you need a lift on the milling table, and is it possible to do without it?

This useful device is called the third hand of the master. Those who have tried a milling cutter with a microlift are finding new applications for it:

Maintaining a power tool is not difficult, as is quickly changing cutters.
You can change the cutter reach height in a matter of seconds, and most importantly – safely.
You can change the immersion depth “dynamically”, simultaneously with the movement of the workpiece on the table. This expands creativity.
Due to the fact that you no longer regularly dismantle the tool for maintenance, the plate and its fasteners are subject to less wear.

Buy or make it yourself?

There is a wide choice of offers on the power tool market. Industrial microlifts look good and work without failures, but their cost is the same as that of a new router. True, the device is quite well equipped. The kit includes rings for the copy sleeves, and a very high quality mounting plate.

All that remains is to electrify the device - and you can get a CNC machine. There is only one drawback, but it outweighs all the advantages - the price itself. Therefore, for periodic home use this is an unaffordable luxury. So our Kulibins make whatever they can. However, there is a lot to learn from them.

There are quite primitive lever-type designs

Homemade elevator design with a lever mechanism

This technique even allows the use of a “foot” drive. It is not suitable for precise reach settings, but with the help of a similar mechanism you can raise the router in one motion working position, and it’s just as easy to lower it for changing attachments or servicing. This elevator has a fairly long stroke; it does not allow for adjustable milling. Materials for production are literally lying underfoot, the cost tends to zero.

Using a Screw Adjuster

Another example of a homemade elevator for a router

The design is more advanced and allows relatively precise adjustment of the reach. However, using such a microlift is inconvenient; to rotate the handle, you need to crawl under the table, and then make a control measurement of the height of the cutter. But the reliability is high, and production does not require expensive materials. Such an elevator can be made “by eye” without using drawings.

The following flywheel design not only makes it possible to precisely adjust the reach in small increments within 50 mm, but is also quite convenient.

Lifting design with flywheel

It will take more time to make, but the result is worth it. The flywheel allows you to adjust the height of the cutter while simultaneously visually controlling it work surface. In principle, it is already possible to dynamically change the cutter offset.

The main advantage is still low cost components for manufacturing, with increased functionality. Instead of a flywheel, you can install a gear and a motor with a gearbox. But this will require additional costs.

Option with car jack

Quite expensive, since at a minimum you need to purchase a jack.

Diamond-shaped designs are ideal.

Application screw jack as a lift for a router, also possible

This microlift lift is reliable, and thanks to the handle located parallel to the tabletop, it is convenient and quite accurate.

Positioning the mount is quite simple. It is enough to install a strong shelf parallel to the tabletop.
An electric drive option is available.

Then, in general, you can install a foot pedal and free both hands. And if you add a programmer to all this, here you have it. homemade router with CNC.
However, this goes beyond the concept of an economy class device.

Option from an advanced master

Since the possibilities of a craftsman are limitless, you can come across completely unexpected designs. This microlift is made using the very milling cutter for which it is intended.

Original elevator design made by hand

The design involves not only precise adjustment of the reach, but also changing the angle of inclination of the router axis. With this potential, you can significantly expand your woodworking tasks.
The drive of the worm gear of the stud – the height regulator – was originally designed.

Gears (gears) are made using the tenon method " dovetail" This allows the gears to be moved outside the mechanism, eliminating the need for lubrication, and making adjustment smooth.
Material used – moisture resistant plywood 20-25 mm thick. The microlift is executed with such high quality - that I would like to suggest that the author organize industrial production.
Of course, such a design requires a preliminary drawing.

Assembly drawing in 3D for a microlift

Moreover, it was made using a three-dimensional modeling program. Making such a device is painstaking work. But financial side question - the cost of a sheet of plywood and a screw stud. When performing custom work, this design will quickly pay for itself.

The verdict on this topic is as follows: when using a homemade milling table, you cannot do without a microlift. Other designs, such as a quick-release plate for a router or a hinged table cover, are only suitable for servicing power tools. And for precise positioning of the cutter above the table, you need a microlift.

Everyone who has a manual router sooner or later comes up with the idea of making a table for it in order to turn it into a full-fledged stationary machine, with the help of which you can implement all the functions inherent in it. I too once had this thought. I will not dwell on the details of making the table; there is plenty of information on this topic on the Internet for every taste and budget. I would like to bring to your attention my version of a lift for raising and lowering the router relative to the table surface. The design is as low-cost as possible, you don’t need to buy anything, everything you need for manufacturing is available in every home workshop.

So, what do we need:
- wooden slats capable of supporting the weight of the router
-bolt with a diameter of 10-12 mm
Metal rod with a diameter of 5-7mm and a length of 100-120mm
-any kind of hinge (door hinge) according to the size of the slats
- old hand drill

The tools you will need are a tap, a die, an angle grinder, a screwdriver, self-tapping screws, drills, etc.
First we will make a nut. Let's cut off the part from the bolt that doesn't have threads, and make the length to match the width of the rail. In the middle of this workpiece, on the side surface, we drill a hole slightly smaller in diameter than the size of the rod (taking into account the subsequent cutting of threads on the rod and in the hole).

We cut a thread along the entire length of the rod, and make a corresponding thread in the body of the workpiece cut off from the bolt. As a result, we got a homemade guide screw pair.

After this, we drill a hole in the rail for our homemade nut (the nut should move freely in the hole, but not dangle in it). Perpendicular to this hole, we drill another one, along the diameter of the rod (a little more is possible). At the other end of the rail we attach a suitable loop (hinge).

Now we insert our nut into the rail, screw a threaded rod into it, clamp the rod into the drill chuck, and fix the drill in the lower part of the table on the front side. We fix the other end of the rail with a hinge on the opposite side. As a result of all manipulations, a structure should be obtained that moves the router vertically when the drill handle is rotated. I don’t indicate any sizes, because... all this is attached, as they say, “in the right place, as you ask for it”

As illustrations, I provide photographs of how I did this. The dimensions can be any, I want to believe, the design principle is clear.

Thank you for your attention.
