Choices for machining sawn wood
Let’s understand how to choose a quarter in the board with our own hands. We buy 2nd grade board and process it in a convenient way. How you can do such a job:
After acquiring the required amount of lumber, the easiest way to select a quarter in the board is to use a circular saw or electric planer. It remains only to give a neat shape to the edges of the product.
READ Let’s saw a board with a circular saw
First you need to make a cut at the end of the board, to a depth of half the height, and then. in the center of the end. Then we set the working width of the board and saw another piece. Here, the depth should be 1.5 times more than half the height to make it easier to remove the sawn-off part. So you can form a finished product with your own hands, twice the price of the original.
In spite of the production with the second type of raw material, the quarter is characterized by excellent characteristics:
It is possible to use this material for exterior cladding.
The Best Router Bits For Beginners
Such saw, involved in the processing of the board, can simplify the process and reduce its duration. If the equipment is powerful and reliable with sharp blades, it is not difficult to set the required parameters.
Working scheme is not fundamentally different from the previous ones, the only difference is that the wood is processed with a circular saw.
Creativity without limits
Milling equipment is indispensable for woodworking. With its help, you can turn a wooden workpiece into an elegant decorative product. This equipment is most often used by professionals, but amateurs with experience can also master it. Using mechanisms is not an easy task, so before you start working with them, you need to ensure comfort and safety. The organization of the workplace is very important. The home craftsman must remember that during the work there is a possibility of damage not only to the cutter or mechanical device, but also to health.
Woodworking. it is not only the work at the machine, but also the preparation of the workplace, planning the sequence of work performed. Before you start milling, you need to find the right type of router for the job, taking into account its shape and size. You should choose the speed of the machine and the depth of cut, and do not forget that the material to be treated must be securely attached to the table.
Depending on the specific type of milling device, the rules for their use differ in many aspects. Vertical milling machines, in which the spindles are located above the work table, are commonly used today. They have proven themselves in such operations as wood milling in the processing of the edges of shelves and round table tops, making grooves, making joints of wooden parts. When processing round structures, an indispensable addition is a special compass with a support plate, which ensures the accuracy of machining.
Working with the router, you must learn to lead it calmly, smooth movements. Correct and safe movement of the material to be machined is key. Do not do it too slowly, because the wood can be stained from the burns, which can lead to damage to the material.
Chips appear when milling wood against the direction of the wood fibers. In one pass must perform milling to a depth of 8 mm, some models allow you to adjust to an accuracy of 0.1 mm. Deep grooves and quarters must be milled in several passes.
Methods of making a quarter
Select the quarter can be several methods with different tools. For example:
The last method. the choice of the quarter with a circular saw. is the most convenient and productive. That’s what we will look at.
If you need planed boards, it is more convenient to plan the boards first and only then proceed to the production of the quarter.
Board with groove: varieties, making a groove with a circular saw, drill and hacksaw
Type of connection, based on the occurrence of the stud in the groove, appeared in Europe almost simultaneously with the floorboards and battens. Finishing material is simple and convenient to install and has many advantages. True, it is more expensive than ordinary boards and slats, but the joints are much neater, and the service life is much higher.
Slotted joints increase the strength of the covering.
What causes drying
A typical case: you have made in your country house shed for storage of household goods and other needs. Made for yourself, so we carefully joined the boards that make up the walls, without the slightest gap. Two or three months pass; the boards dry out and the entire wall glows with cracks. In winter snow blows through them, in summer the wind blows dust inside the barn.
Drying is up to 10-13% of the linear size. That is a board width of 100 mm after drying out reduced to 88 mm.
To prevent this from happening, boards with a quarter joint should be used for sheathing. A wall paneled with these boards will never have a through gap. Neighbouring boards overlap each other with their quarters and no more cracks appear when they dry out.
Unfortunately lumber is very seldom sold with already finished quarter. Therefore, the amateur craftsman should know the ways in which boards are refinished when necessary.
What tools do you use??
Methods of making grooves, tongue and groove differ depending on the arsenal of tools you have, as well as whether or not the finished connection will be in view after the final assembly of the project. (See the chart below for a comparison of the advantages and disadvantages of these methods.) Remember that some joints can be hidden behind the facade frames, and a more or less even groove can be made even better with special milling cutters (see. groove cutters will take away sawing errors).
Although they have much in common, these grooves differ depending on their position in the wood. A groove forms an L-shaped depression along an edge or face. The groove has two shoulders (walls) and is located across the direction of the fibers. A tongue and groove also has two walls, but it is arranged along the grain.
FIVE WAYS OF GROOVING, TONGUE AND GROOVE
|TOOL||RESULT EVALUATION||PRICE||OTHER APPLICATIONS|
|Recessed groove plate||Advantages: cuts cleaner than most conventional discs; fine thickness adjustment with spacers||Disadvantages: Leaves triangular grooves in the corners of the outcrop; when working crosswise, a backing board is needed to prevent chips||80-250||Forming cleats, box joints, half-tree joints, etc.|
|Adjustable groove disc||Advantages: quick and easy set-up; affordable price||Disadvantages: Uneven tapping bottom; cross grain work requires a backing board to prevent splintering||50-80||Forming cleats, half-tree joints, etc. п., but with low quality requirements|
|Combination saw blade with 40 or 50 teeth||Advantages: eliminates the need for a saw blade; makes clean joints when working crosswise||Disadvantages: the need to make several passes, which is time-consuming and often leads to errors; traces of teeth require brushing; when working across the fibers to prevent chipping, a retaining board is required||10-80||Longitudinal and crosscutting sawing in conventional sawing operations|
|Straight mill||Advantages: Makes clean, rectangular recesses; excellent precision when cutter diameter matches slot or groove width||Drawback: deep cuts are made in several passes; when working crosswise, a backing board is needed to prevent splintering||5-20 per burr or 30-100 per set of 6 to 9 burrs||Nesting, milling along a template, smoothing over rough surfaces|
|Reamer cutter||Advantages: Makes clean grooves when hand milling and on a router table; setting up is faster and easier than with a straight router||Disadvantages: deep rebates are made in several passes; when working across the grain, a backing board is required to prevent chipping; may tear veneer edges from veneered surfaces||10-40 per cutter or 20-60 per set with multiple bearings||Not intended for other operations|
Special milling cutters
For decorative patterns, for example, ornaments, fonts, V-type (conical) engraving cutters are used. In this case the milling machine is moved by hand freely along the marking. Thrust milling cutters with stop center and undercutters are used for drilling and tapping holes. Holes for dowels are drilled with routers 06, 08 and 012 mm. Use router bits 015-35 mm for furniture fittings. When using larger diameter milling cutters, the milling machine should be switched to lower rpm.
Some cutters can be used to form two mutually matching profiles, one of which is a reciprocal. It can be a set of two separate milling cutters that complement each other (“counterbore”), or it can be a single cutter that creates its own counterbore when the workpiece is turned to the other side.

A milling machine is a device that can be used to machine materials such as steel, metal, wood, plastic and stone. Cutters can be used on different surfaces, both flat and even curved.
The machine has the ability to make splines and serrations, as well as threading, drilling, and even boring parts.
over, with the help of milling cutters the craftsman can make a beautiful ornament or even an inscription on the surface of the part, and still be able to perform a number of other works.
How to choose
When it comes to buying a brand-name device, you first need to estimate how much guidance you need in your home arsenal. If it is to be used all the time, it is advisable to read the manual with the richest configuration with all bolts, clamps, conveyor and ruler. For occasional use, you can buy basic equipment with a minimal set of functions.
When choosing, it is also necessary to evaluate the characteristics of the circular saw. Saw diameter, motor power, platform size, and functionality. From a practical point of view it is necessary to evaluate the possibility of circular work with different materials. Wooden boards, planks, furniture panels. It is important to choose the right length and width of the guide, so that it is longer than the workpiece by 2 lengths of the sole.
