Regardless of the fact that nowadays the offer of already prepared painted linen is large and it is, of course, much easier to buy ready-made canvas and immediately throw on painting, there are still painters who are preparing their canvases for their works. To some, this is the introductory ritual in the creative part of the work, but some do not have the confidence in the durability of what they did not do themselves. There are those who need specific dimensions, or their method of painting does not correspond to the properties of the universal coating, they do not correspond to the thickness of the canvas or its structure.
Another reason for the decision to fall on the separate purchase of tie-bars from which the blind frame is connected and the purchase of the canvas in the roll that is placed on such a frame is transport – painters are those who have the opportunity to travel frequently and carry the painting material with them. And if you have a reason and you decided to combine your frames yourself and spin the canvas, it will be good to read the troubleshooting tips that may arise on that occasion.
The problem of selecting the appropriate slats
When you know what dimensions of the frame you need, you will first of all start purchasing the slats. As simple as it sounds, you have to be careful and well plan what and how many slats you need because the stability of the frame depends on them. The insufficiently stable frame carries the risk of being spun when you tilt the cloth onto it, and the image placed on the wall does not look good.
The strips must be distinguished by the fact that they are tensile (for the sides of the frame) or in the middle bars that give the frame firmness. Also, you need to pay attention to which of the middle slats have a tooth with which you will put them in the basics, which of them have a craving in the middle, thanks to which you can cross them and provide exceptionally large formats (gallery), which do not have recesses and additional teeth (standard ). Your frame can be one of the following types:
A ram whose sides are up to 70 cm long
If no side of your shoulder is larger than 70 cm, it will suffice to take only 4 tensile battens. So, if the dimensions of your frame, for example, 70×50 cm, you need two 70 cm slats and two 50 cm laths, and the middle bars are not necessary.
However, if you like, there is a possibility that even a small frame is reinforced with a medium sling. You will calculate its length by removing the width of the shoulder width from the length of the shorter side of the frame from both sides. So if the width of the slats you use is 3.5 cm – then you need to take the central slat 7 cm shorter than the shorter side. So if you have a frame of 50×70 cm, the central slate should be 43 cm in order to fit exactly in the middle of the longer page. Given that the slats less than 71 cm have no tooth with which you will tie them in the frame, their length is usually two millimeters larger in order to be stuck in place between the tension rails for the frame – is not it?
Ram dimension larger than 70 cm
When it comes to frames with one or both sides longer than 70 cm, medium battens are required, which will make the frame more firm and inelastic. For example, all the tilt bars Gallery longer than 70 cm have a side recess in which you will fit the middle slat. And all the Galleries of Medium Medium Slats longer than 70 cm have a tooth that will insert in this recess, so you will be completely clear how this frame connects.
Let’s give you an example to make it clearer. Let’s just want to frame 60×90 cm from Gallery strips that are 4.5 cm wide.
– 2 tensile strips 60 cm in length
– 2 tensioning strips 90 cm long
– 1 medium slat length 51.2 cm [60 cm – 9 cm = 51 cm] due to the width of the tensile strip of 4.5 cm, we must take 2-fold left-handed left shavings from the shoulder width
(it is placed in the middle of the 90 cm slats)
Unusually elongated formats
Where you can find yourself in doubt is the elongated formats. You will probably be wondering which type of middle slats in such cases to choose and folding such a frame is indeed the most complicated business.
Our advice is to use medium-sized battens for elongated frames.
For example, to create a frame that is in the dimensions of 150×50 cm, the width of the slats 4.5 cm, select the following battens:
– 2 tensile strips 150 cm long
– 2 tensile strips 50 cm in length
– 2 classic medium battens of 41.2 cm which you will set at the same intervals. These slats are for a reason longer than 2 mm and for no reason have a tooth with which you can snap them into the recesses. You can place them anywhere else in the frame, but it’s good to put them in symmetric spaces. Depending on the length of the longer page, you may need one middle sling, two, or three in extreme elongated frames.
