Cutting with a power plier: the outer corner

Most often, when installing ceiling plinths, home craftsmen are interested in how to properly formalize the inner corners in the room. Cutting outer corners is made less often, but with a certain wall layout and it is necessary. Let’s look at how to properly make an interior fillet, using a special tool (a chair).

First you will need to buy a plier. This tool is a tray in which the part is fixed, and it is trimmed. In order to measure the length of the desired product, you need to attach it to the ceiling. Next, it is necessary to establish a plinth in a chair. Its positioning should match the position it will occupy on the ceiling.

Chisel

How to properly cut the inner corner of the ceiling plinth. not a simple question, to answer which the corresponding photos help. Experts recommend studying them, and only after that should you start working.

After you make sure that the product is positioned correctly in the tool, you can proceed with the cutting itself. The hacksaw must have a certain angle, namely: 45 degrees. During the work, it is not recommended to put a lot of pressure on the cutting tool, as it is possible to damage the surface of the chair. Then the trimming of the adjacent fillet is performed, which is done in a “mirror” manner.

And how did our ancestors?

In the olden, olden days, when power tools were not yet sold freely in stores, our ancestors also mounted baseboards and all sorts of other decorative details. And they were pretty good at it. To mark a part for an actual angle, you need to take a part of the ceiling plinth, put it to the corner you are going to work. Do this carefully, pressing the ledge against the ceiling and wall. And apply the fishing line along the ceiling and along the wall at the intersection of the piece. Then do the same operation on a perpendicular wall.

On the ceiling you will have two intersecting scythe lines. If you connect the intersection point of the lines and the intersection point of the wall planes, that will be the line by which you want to cut the details. Now it remains to transfer this fishing line to the detail ceiling plinth. Having put the ceiling skirting once again to its intended place, mark on it the point of intersection obtained on the ceiling. At the bottom also mark the point where the wall ends. Connect these two points with a straight line. This is the sawing line on the part. Try to keep the hacksaw perpendicular when sawing to minimize inaccuracy.

What tools can be used?

The appropriateness of certain tools depends on the materials, of which the skirting board will be made.

Table. 1. Types of materials and peculiarities of their use.

Type of material Material properties, requirements Tool

Polyvinyl chloride (PVC)	PVC skirting boards are notorious for being easily damaged when pressed and can no longer recover their former appearance, as they lack elasticity. That is why you should not put pressure on these skirting boards when cutting them.	Use a construction knife or a metal saw. A blade or a sharpened kitchen knife will also do.
Styrofoam	Plastic skirting boards are also not very firm, but they are better than their PVC counterparts. It crumbles easily.	The same tools can be used as for PVC
Wood	Stronger and more aesthetic than its polymeric counterparts, but expensive.	Wood is best cut with a hacksaw, maybe on metal, though you risk clogging the teeth of the blade with wood shavings. A fine toothed wood saw is best.

How to get the right angle

Inside is laid the part in which to make a cut, the saw is inserted into the guide. The part is held in place, cut at the desired angle.

• The slat that will be fastened to the left should be on the side of the jigsaw closest to you, and should lie with the bottom up. The hacksaw should be inserted in the farthest right and the closest left cut;
• The bar which will be fastened to the right, is put in the same way, but the hacksaw should be inserted in the far left and the nearest right cut in the wall of the jigsaw.

If you have inner corners to be refinished, proceed as follows:

• The bar to be glued on the left side must be on the bottom side up and on the side closest to you. The cutting tool is inserted into the far left and the near right of the cut.
• Baguette which will be mounted on the right, is put in the same way, here the hacksaw should be inserted in far right and closest left slots.
