TO BE FRAME PERFECT

Any frame — big or small — design “strict”: makes serious demands on the butto-ness of angles and their careful execution and connection. To simplify the manufacture and to get a quality frame with less effort, the French magazine “System D” offers two simple and convenient devices, which you can do yourself: a tablet for cutting sticks or baguette and a press for bonding of the workpieces.

The corner – not to the eye

When you run the workpieces frame the most difficult to cut them at a 45° angle. At l’om and is intended to help the tablet, which will be a good addition to a small circular saw or jigsaw and will replace the traditional fixture is a mitre box that is used when working with a hand saw.

The tablet consists of a small wooden shield – base and two thrust rods, installed strictly at an angle of 90° relative to each other. The base of the tablet — Board of hard wood of 25 mm thickness and approximately the size of 400×250 mm. Instead it can be used and furniture SIG or chipboard.

On one side of the base is a small propyl — gap, which will be held the saw disk or blade of the jigsaw. On both sides of the cut with a space in it the width of the attached two resistant bar counter with the ends sawn off strictly at an angle of 45°. That’s all the device tablet. It is convenient to use on the saw table, which for this purpose are milled two parallel groove, and two return rails they are mounted on the bottom of the tablet. Thanks to them, the tablet can slide with slight friction on the guide grooves, strictly maintaining the direction of its submission.

Raspilovochnyj tablet:

1 — base; 2 — guides; 3 – propyl; 4 – resistant bruski; 5 — screws
 

Install the retainer:

1 — connector with holes; 2 — square-latch; 3 — protecting strip

Pictured shows how installed tablet with a billet frame and how it is fed into the sawing at the movement of the tablet guide grooves in the side of the saw.

To cut a baguette on one side of the frame, it is necessary to lay out its internal dimensions with a pencil. Then a pressed baguette (outside) to the corresponding thrust bar so that the mark length came against the slot. Now, when moving the tablet toward the saw blade baguette sawn at a 45° angle automatically. In the same way cut the ends of all other rails forming the frame.

Press for bonding

However, to prepare frame parts — even half the battle. The next task is to securely glue together. Here to help out a very simple press to assemble them. It consists of four tie-rods — wooden slats from solid wood with a section of 30×30 mm, with drilled holes in them with a diameter of 4 mm. Ties are pairwise connected by a hinge — connecting bar sizes 100x30x30 mm bolts and nuts (wpoty). In addition to the four ties are made of a square-lock. They are cut from wooden bars of solid rock with a thickness of 30 mm. Each of the clamps has a bottom spike is screwed in a screw with a diameter of 4 mm with cut head.

Press for gluing the frame:

1 — ties (perforated slats); 2 — connecting loop; 3 — elbows-clamps; 4 — clamp

A set of tools for bonding the frame in the working position

In order to actuate the press, the screed is laid on a flat surface (table) in the form of the letter X. depending on the size of the frame in the corresponding holes of the couplers is inserted into the clamps. It remains to apply glue to the joints of the framing strips, to be connection “on a mustache”, and put them in the clamps. Now you need one single strubtsinku. With her help, pulled together by the connecting bars of the screeds, and means — and baguette-tips in place, ensuring a tight connection and holding in position until the glue sets.
