The stretcher serves as the basis for stretching the canvas. To date, a stretcher with a modular connection is the most suitable for this purpose, since the canvas can sag during work and storage. Modular design allows using wedges to align and stretch the canvas as much as needed. Subframes come in different configurations: there is a subframe with a side, and there is a trapezoidal one. In the manufacture of a modular connection on a subframe with a side, the hassle is much less than with a trapezoid, since it has two planes from which you can push off for milling a groove and a tenon, which cannot be said about a trapezoid. The latter has only one base plane and you can only start from it.
The machine for manufacturing a modular subframe MP-02 allows you to tune in to any type of subframe. Having two MP-02 machines available, you will be able to set the first one for groove milling, and the second one for tenon milling, thereby making the setting very easy and convenient and this will speed up the production process by at least 4 times.
There is a discount for buying two machines.

Aluminum subframe
Made from light anodized metal. The cost of such a high quality stretcher is comparable to the price wooden product. Among the advantages, users indicate:
- ease of construction;
- durability;
- moisture resistance.
A significant drawback that aluminum canvas stretchers have is the presence of sharp corners and edges. Products require a certain skill, otherwise you can easily damage the canvas.
plastic stretcher
PVC products are characterized by low price and versatility. A high-quality plastic stretcher can be as functional as a wooden one, but finding such a product is quite problematic. Mainly on Russian market presented cheap plastic products made in China, which quickly become unusable. Professional artists and art lovers are extremely negative about plastic stretchers and note many shortcomings:
- the difficulty of stretching the canvas;
- low strength;
- the occurrence of deformations;
- sharp corners and notches.
Plastic accessories can only be used for very small paintings.
Wooden stretcher
Wooden stretchers for attaching the canvas are made of solid wood (beech, oak, pine and birch). The material must have a moisture content of no more than 20%. No knots or defects larger than 0.2 mm are allowed. The surface of the wood should be uniform, without blue. good producers and craftsmen who make products to order must treat wood with a special compound that increases the resistance of the finished accessory to humidity and temperature extremes. A quality wood product can last more than 25 years without losing its performance properties.
Our company produces classic solid pine subframes. In the manufacturing process, only high quality wood is used, which contains a minimum of moisture (up to 10%) and does not have any defects (cracks, resin sinuses, knots).
Classic subframes
As a rule, the stretcher rail can be from 3 to 6 cm wide, depending on the size of the canvas. Also, large, overall, subframes are equipped with a special cross or crossbar with a base to strengthen the frame, preventing sagging.
Conclusion
The quality of the used stretcher depends on the safety of the canvas, paintings. When choosing this indispensable accessory, it is necessary to give preference to well-known manufacturers who use only high-quality and eco-friendly materials. The product must be neat appearance, certificate and packing for transportation. Companies selling and manufacturing canvas stretchers that value their reputation in the world visual arts, will never offer the buyer a product of dubious quality.

Hello dear DIYers, as well as artists and restorers.
In this article, we will learn how to make a modular stretcher for a picture, and in the following we will give it an ancient look and stretch a canvas over it.
Purpose and functions of the modular subframe
A feature of the modular stretcher is floating corner joints, which allow stretching the canvas of the picture with the help of wedges, like a drum membrane.
This is especially true on canvases of medium and large sizes, approximately 40 x 50 cm.
When stretching the canvas on a stretcher of this size, and then priming it, irregularities appear on the canvas after exposure to gelatin.
For example, the canvas before the primer, after it and after pulling up with wedges.
Waviness can also appear after further priming with acrylic, and later with too temperamental exposure with a brush or spatula, in any case, on a modular stretcher, you can always tighten the canvas with special wedges, for which special nests are provided in the corners.
How to make a modular stretcher
We have to make such a structure
The minimum thickness and width of the bar, at which the connection will be reliable, is 20 x 40 mm, and such dimensions are relevant for frames with a side length of up to 50 cm.
With dimensions of more than 50 cm, a more powerful bar is needed. Otherwise gusset will not provide the necessary rigidity when tightening with wedges, and the strips will begin to move towards the tightening, forming a screw along the plane.
The corner may even break and all the work will go down the drain.
The connection should be pretty tight, because. loosening again will allow the slats to change position when stretched, which will lead to the general plane of the web.
As you can see, the requirements are quite strict, which means that to make a quality connection hand tool it will be very difficult.
Buy special equipment it’s expensive, it’s easier to buy the stretcher itself, but to make it on a simple woodworking machine (popularly a circular), it’s quite possible, you just need to make a rigid ruler for it.
I also used a miter saw, but a regular miter box can replace it.
We will make the first frame 40 x 50 cm in size from a bar 20 x 45 mm.
We choose bars preferably without, or with small knots. Large knots are completely unacceptable, and even small ones should remain in the middle part of the plank, as far as possible from the ends, since it is in the knot area that a crack and even a chip can occur.
We make 4 blanks exactly matching in length in pairs.
Since the thickness of the bar is 20 mm., And we have to make one groove, one comb and two samples, that is, only 4 elements, then each element will have 5 mm.
To make a clear groove 5 mm wide. would need Circular Saw with a cutting width of 4.5 mm. Taking into account the natural microbe, the cut will be 5 mm in the red.
If it is possible to buy a disk of the required thickness, then there are no questions. I did not find this, so I paired two discs with a cutting width of 2.5 mm. each. The result is the required 4.5 mm.
We set the support frame at a distance of 5 mm. from the disk, and the distance is measured on both sides of the disk from the bar to the tooth. The overhang of the disk (cut height) is set along the width of the bar, in our case 45 mm, after which we make the same cuts from all ends of the workpieces (in the picture of the workpiece into two frames).
For now, let's leave the groove in this form and deal with oblique selections.
In order not to be mistaken, let's lay out the frame on a flat plane so that the groove in the corners coincides with the future crest, i.e. the thin part above the groove fits the thick part of the adjacent plank, and note the direction of the sampling angles.
Then we set the miter saw to a cutting depth of 5 mm. minus and cut off at an angle of 45 ° the thin part of the connection and make a cut in the thick one. The angle of inclination of both cuts must be opposite.
As a result, all the ends of the blanks should look like this
Now you can return to the groove while the reference ruler is set to 5 mm. from the disk and we already know exactly what surface of the workpieces will be internal, from which the wedges will be installed.
If, in the resulting state, bring the workpieces to each other in the way that they will then be connected in the frame, then there is no place in the groove for the wedge, so you need to make it, and make it with a slope.
To do this, we introduce the workpiece with a groove on the disk until it stops, and then at a distance of about a centimeter from the end of the workpiece, we put the stopper.
Now you can remove the workpiece, turn on the machine, and cut the grooves for the wedges, first on one side, then in exactly the same way on the other. In this case, the grooves turn out to be beveled.
For comparison and better understanding - one blank with a groove, the other without.
It remains to make the last oblique selection and at the same time the ridge.
To do this, we bring the ruler close to the disk and make selections from one side and the other, bringing the workpiece, respectively, to opposite sides of the disk. We clean the remains with a knife or chisel.
Now the connection is ready, but that's not all. There is one more nuance. The artist will not like it very much if the canvas touches the frame, and it is 45 mm wide, so on the front part you need to make a side that will provide a gap between the frame and the canvas.
To make such a side, first we assemble the frame, it must be assembled very tightly, with effort, and we will admire the clarity of the joints and the absence, or almost the absence of any cracks, and then mark the front plane.
We remove the second disk from the machine, and bring the ruler even closer to the first one, it is even possible so that it bites into the ruler a little, about a millimeter, so that it can choose one and a half millimeters, no more, we raise the table to reduce the overhang of the disk to 40 mm, and skip all the blanks on the front side.
After that, you can assemble the frame, and once again admire the finished product.
A small modular stretcher is ready. Stretcher big size is done similarly from more powerful rails.
If the size of the stretcher reaches a meter or more, then it is made cross bars or crosses.
Allowed amount from 10 rubles. up to 15,000 rubles
The stretcher is a frame made of wood, on top of which the canvas is stretched. The safety of the canvas depends on the quality of the specified element. Therefore, in order for the subframe to serve in good faith for many years, it must be manufactured in accordance with certain rules:
1. The size of the stretcher must match the dimensions of the painting itself.
2. Only dry wood must be used in the production process.
3. The product must be strong enough.
4. In the manufacture of this device, it is necessary to provide for the presence of special bevels on the rails.
The canvas itself is stretched over wooden stretcher in such a way as to ensure that the direction of the threads of the fabric is clearly aligned with the direction of the rails of the subframe. This operation can be carried out in two different ways:
1. Standard stretch. By means of it, usually, hand-written paintings, some reproductions, as well as photographs are drawn up. The canvas, at the same time, is fixed on the side ends of the subframe with the help of brackets, after which it is inserted into the frame.
2. Gallery stretch. In this case, the edges of the canvas are wrapped around the edges of the stretcher and attached to it. back side. This is the case when the canvas is to be used without a frame.
Quite often, modular stretchers are used for an hour of stretching the canvases. This happens when the size of the picture is very large. In such cases, additions such as a cross or a transverse jumper are used.
Modular subframes, unlike simple ones, take much less space. In addition, the presence of side wedges in them allows you to significantly strengthen the tension of the canvas so that it does not sag.
Framing workshop Artland is engaged in the manufacture of stretchers (simple and modular), as well as standard and gallery stretching of canvases. Along with this, professional craftsmen will perform more complex operations to order:
- duplication of the canvas;
- summing up the edge;
It should be noted that the duplication of the canvas is a rather useful manipulation, since it helps to weaken the vibrations of the canvas during an hour of transportation or exposure.
Vibration provokes loosening of the particles of materials through which this or that picture is made. An event such as duplicating the canvas will reduce unwanted loosening and ensure better preservation of the painting.
As for the summing of the edges, the indicated actions are performed in such cases:
- it is impossible to make a constriction of the picture;
- it is impossible to stretch the canvas on a stretcher;
Leading the edges will allow you to carry out the above manipulations and preserve the appearance of the canvas.
It is important to note that the Artland framing workshop offers its services at very affordable prices, guaranteeing customers a high quality result.
