Hello, dear readers and homemade products!
In carpentry, in the manufacture of various frames, platbands and other parts, blanks must be trimmed at an angle of 45 degrees. This operation can be performed both on a miter saw and on a circular saw.
In this article, the author of the YouTube channel “망치 소리 Hammer sound” will tell you how to make a miter carriage for a circular saw adapted to these tasks.
< a href = "https://usamodelkina.ru/uploads/posts/2021-05/1621206874_45k-005.jpg" rel = "prettyPhoto"> This project is not very difficult to manufacture, and can be repeated in a small carpentry workshop.

The first step is to assemble a box to stop the carriage. It consists of two wide strips of plywood, and two narrow ones.
First, a strip is inserted into the groove of the sawing table, and the first wide strip is pressed against it with a parallel stop.
The first narrow strip is pressed against the parallel stop, and is aimed at the bottom strip. So the author gets a flat plane on one of the edges of the box.
A guide will move inside the box, it is also made in the form of a strip.
In order for it to move freely inside it, a strip of masking tape is glued to its edge.
The guide is pressed with a second narrow strip, and the latter is fixed with a nail gun.
To create a gap for the guide in a different plane, masking tape is glued to both narrow strips, wood glue is applied. The last wide strip is pressed down from above, and is also targeted by carnations.
After the glue hardens, the master proceeds to processing the box on a milling machine.
In the upper part of it, you need to prepare a groove for the T-track. Setting the overhang of the straight cutter equal to the profile height, the groove is milled. The cutter diameter must be equal to the profile width.
The following insert with replaceable rings is installed in the milling table.
Now, on a miter saw, one end of the box is cut at an angle of 45 degrees.
On the other hand, the workpiece for the movable block is cut, and at the same time the ends are aligned.
Having cut out the rectangular base of the carriage, the remaining part of the stop is laid out on it parallel to the wide edge. The contours of the stop are transferred to the base, and the center of the hole for the hold-down bolt is marked.
From the upper side of the base, starting from the marking lines, thin through holes are drilled.
The base is turned over, and the resulting holes are countersunk with a wood drill with countersink .
After drilling the through hole, insert the bolt and tighten the nut. Having circled her kennels, and removing the nut, the master makes a hole for it, removing the excess material with a chisel.
The nut is pressed into place.
A counter hole is made in the lower part of the box.
Taking into account the dimensions of the cut block, a square segment is cut out on the base.
The saw blade does not allow cutting to the end, and the author completes this operation with a Japanese saw. The cut part is saved.
Further, the emphasis is pressed against the base with clamps, the structure turns over, and the parts are pulled together with countersunk screws.
After assembly, the master controls the angle of 90 degrees on both sides of the stop at using a checking square.
Now a somewhat complicated operation – you need to cut off the extra corner of the base, exactly maintaining an angle of 45 degrees between the carriage stop and the parallel stop.
Here Svenson's square comes to the rescue. The corner of the carriage rests against the parallel stop.
Thin strips are inserted into the T-shaped groove of the sawing table, and a guide bar is placed on top of them.
Next, the required distance from the parallel stop to the saw blade is calculated and set, taking into account its thickness of 3 mm.
Putting the carriage on the guide, and resting the bar against the parallel stop, stick to the guide two triangular blocks on both sides of the carriage. To avoid displacement, they are fixed with masking tape.
Now you can remove the auxiliary bar and remove the shims from the groove. < br> Pilot holes are made in the guide, and it is screwed both to the corners and to the base.
Finally, you can remove the extra corner.
To control the angle, two right-angled triangles are cut from one board. The 90 degree angle is controlled by a test square .
Auxiliary corners together with excess guide are cut flush with the edge of the carriage base.
The solution is quite simple – to make hooks for the T-shaped groove in the sawing table.
For this, holes for self-tapping screws are drilled and countersinked in enlarged washers.
Using a grinder, you need to grind off the edges of the washer.
< a href = "https://usamodelkina.ru/uploads/posts/2021-05/1621206905_45k-288.jpg" rel = "prettyPhoto"> A pair of these washers are applied to the sole of the guide. With a self-centering drill pilot holes are prepared and washers are fastened with self-tapping screws.
Now the carriage can only move in one plane.
Of course, there are special guides for T-tracks (sliders) .
Aluminum T-tracks are fixed in the grooves of the stop and the block.

The block is screwed to the rail, and the previously cut square from the base is attached to its bottom side.
The excess rail on the other side of the carriage is cut off.
Inside T- track, a T-bolt is inserted.
A movable limiting block is assembled from several parts, at the base of which a cut is made at an angle of 45 degrees.
The position of this block is fixed with a wing nut.
Before gluing the scale, the master cuts out the control sample.
self-adhesive measuring tape .
The second part of the tape is glued to the edge of the guide.
This is how the author obtains a retractable bounding block that allows precise cutting of long workpieces.
Having set the desired position of the limiting block, the guide is clamped with a screw from the underside of the carriage .
It remains to make a control cut and check the accuracy of the carriage.
I thank the author for a master class on making an angular miter carriage for a circular saw.
