I apologize for my bad English, but I would really like to share my home-made.
During the construction of the frame house I had to do a lot of sawing at 90 degrees. It was necessary to do this quickly and efficiently.
Ready-made saws from the store for this purpose are not suitable because they are too heavy and have a high base which is very inconvenient when working with a heavy board 6 meters long.
Therefore, I made a simple fixture for precise cutting of wood at an angle of 90 degrees using a hand-held circular saw.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: The Foundation
As a base, I made a box with a side height of 50 mm. Box length 60cm
Step 2: Base for Saw
The saw is mounted on a base made of a piece of laminated flooring. A bar and a furniture hinge for lifting the saw are nailed to it.
Step 3: Guide Rail
For precise cutting, small bars were installed along the base cuts and the saw was cut to the maximum depth using a saw.
In this case, the main thing is to observe the cutting angle of 90 degrees, the quality of further work will depend on the accuracy of this cut.
Step 4: Check
Now you can check the accuracy of the drink
Step 5: Painting
Для красоты я зачистил все приспособление спомощью шлифовальной машины и покрасил специальной краской для древесины
Step 6: Finish
The fixture is ready. You can use.
The design turned out to be very light and comfortable and allows you to very quickly saw off boards up to 50mm thick and up to 200mm wide.
Now this is my favorite device at the construction site.
