How to make a 3D miter box – “manual” analogue of a miter saw

Hello dear readers and homemade products!
How to make a 3D miter saw & mdash; < a href = "https://usamodelkina.ru/uploads/posts/2021-03/1615326408_to-001.jpg" rel = "prettyPhoto">How to make a 3D miter box & mdash; Many of you have experience in cutting beams, boards, and other wooden materials. It is practically impossible to cut off the end face by hand without special devices.
To solve these problems, modern workshops are equipped with a miter saw. However, not everyone can afford to purchase such a machine, and it is difficult to use it at home.
Of course, there is also a classic joinery called wort. Often they are made of wood or plastic – for this reason, its service life is not very long.
In this article, Viktor Nikitin, the author of the YouTube channel “RotorCore”, will tell you how he made his own kind of miter box that tightly controls the saw blade and the cutting plane. In contrast to the classical version, in this device the inclination of the web can be adjusted in two planes at once, and very complex trimming operations can be performed.
This project is quite simple to manufacture. Despite the welding used in this case, you can do without it.
Materials necessary for home-made.
– Steel angle 63 × 63 × 5 mm
– Elongated nut, washers, stud m8
– Circle cut-off, flap stripping
– Welding wire.
Tools used by the author.
– Bulgarian
– Drilling machine
– Welding machine, magnetic corners
– Multifunctional guide for drill
– Protractor
– Ratchet tap holder, tap, semi-automatic core
– Caliper, square, marker, vise, file .
Manufacturing process.
A piece of steel angle 63 × 63 mm, rib thickness 5 mm, will serve as the base of the miter box.
