DIY adjustable angle carriage for circular saw

Hello, dear readers and DIY!
When working with a circular saw, two conditions must be observed – safety and convenience. This is especially true when you need to make a cut at an angle, or cut a small part.
In this article, the author of the YouTube channel “Gonzalo Ré” will tell you how to make a carriage for corner cuts with workpiece clamps.
Adjustable angle carriage for circular saw do it yourself This is a very simple project, and it can be easily repeated in a small carpentry workshop.
Materials required for DIY.
– Cam clamps
– Bakelite wing nuts
– Furniture wing nuts
– Sheet plywood, board
– Bolts, wood screws with countersunk head
– Titebond wood glue, sandpaper.
Tools used by the author.
– Hand router, wood cutters
– Wood cutter dovetail
– Screwdriver
– Wood drills with countersink
– Circular saw
– Svenson square, malk
– F-clamps
– Tape measure, combined square, pencil .
Manufacturing process.
The first step is to cut a rectangular carriage base from 12mm plywood. In Spain, plywood is made not from birch, but eucalyptus.
Two strips are also cut out for a movable guide. Their length is the same as at the base.

This technique cannot be called convenient, and it is inapplicable if it is necessary to preserve the entire front surface of the product. In this case, it is much easier to put some coarse salt on the glue.

Adjustable angle carriage for circular saw hands From the narrow edge of the guide the author steps back 70 mm, and marks the line with combined square . From the ends of the resulting line, you need to retreat 30 mm and put marks. The same marking is done on the second edge of the base.

Adjustable angle carriage for circular saw hands Installing an 8-mm straight cutter for wood , and by adjusting the position of the parallel stop, the slot in the base is milled. One of the holes just serves as the entrance for the cutter.

Adjustable angle carriage for circular saw hands  Adjustable angle carriage for circular saw do-it-yourself Without changing the position of the parallel stop, the master installs a larger diameter cutter and sets its overhang at 4 mm. This is how the undersides of the base are milled. The result is two T-shaped grooves.

A wide groove 10 mm deep is cut along the center line of the guide.

This is how the master processes both edges of the groove, obtaining a trapezoidal section.

Adjustable angle carriage for circular saw do-it-yourself Adjustable angle carriage for circular saw hands Two counter holes are drilled in the guide for clamping screws. The distance between them is the same as between the grooves in the base.
Adjustable angle carriage for circular saw hands Having inserted the cutter into the hole, the master mills the groove in both directions (30 mm from the hole ) along the centerline.
This will allow you to change the angle of the guide relative to the base.

This will provide additional rigidity of the movable joint, as well as increase the maximum clamping height.
During gluing, the parts are clamped in clamps .

Pilot holes are drilled for them using wood drills with countersink .

 Adjustable angle carriage for a circular saw with your own hands Adjustable angle carriage for circular saw hands Thanks to such clamps, you can fix both large and very small parts on the carriage. < br> The height of the clamp can be adjusted with the clamping screw or with shims.

The workpiece is laid out on the carriage, the desired cutting angle is set, and the guide is fixed with clamping nuts.

There are also special sliders for T-tracks , which ensure smooth running and no backlash.
With this carriage, you can cut even at a very sharp angle.
