All about the jig for the "oblique screw" connection

Having found out everything about the jig for the "oblique screw" connection, you can use it as efficiently as possible. In addition to the principle of working with a conductor on a "oblique screw", it is necessary to find out the general characteristics of the joints and fixtures of Kreg and other models. It is also worth dealing with the drills to get the best results.

It should be said right away that such a device as the "oblique screw" conductor is used only in working with wood. Sometimes it turns out to be more effective than dowels, screws, and dowels. This is a situation where it is necessary to connect flat parts that are too thin for the use of studded structures. At the same time, it is impossible to resort to external fasteners, mainly for aesthetic reasons. The connection of the "oblique screw" type is not new in the joinery and carpentry business for a long time, but nothing better has been invented for this task yet.

Many craftsmen make conductors with their own hands. Whether to do the same or buy a finished product - you have to decide on your own. Both options cope well with practical tasks.

Has a fairly high popularity Model Trend Mini Pocket Hole Jig... It is suitable for a wide variety of secret screw pockets. There are 11 types of joints.

Other parameters:

• the thickness of the workpieces is not less than 1.6 and not more than 3.8 cm;

• the largest width of the clamped product - up to 3.8 cm;

• permissible distance between drilling points - 1.8-5.4 cm;

• the recommended drill section is 0.95 cm;

• application with a square bit of the 2nd number;

• calculation for screws number 7x30;

• precise clamping adjustment;

• production at a British enterprise.

The delivery set includes:

• lengthened and shortened clamping platforms;

• drill 0.95 cm with a stop;

• 15 cm square bat;

• 50 screws with a square slot;

• a pair of hex keys - 0.25 and 0.4 cm.

It is worth paying attention to KMA3220 by Kreg. Main characteristics:

• calculation for perpendicular drilling;

• 6 guide elements, 0.5 cm each;

• clamp;

• limiting device included in the delivery set.

Good results are also obtained by using Kreg K5MS-EUR... The delivery set of such a conductor includes a three-inch pliers, as well as a base for a mobile conductor. The drill stop can be removed if necessary. In the working position, in spite of this, it is firmly fixed with a stopper.

Other features:

• comfortable thought-out mechanism for cleaning dust;

• the ability to adjust the ratchets manually;

• adjustment of the stop of parts;

• 3 guiding elements;

• work with materials from 1.2 to 3.8 cm;

• drilling intervals - 1.4, 2.2 and 3.6 cm;

• embedding the clamp into the fixture itself.

The delivery set includes:

• restriction ring;

• adapter swiveling for a vacuum cleaner;

• conductor extension;

• hex key;

• wooden plugs (5 pieces);

• a portable conductor base (and a few more items, including an English-language instruction).

The jig K5-EUR is supplied under the same brand. Large support "wings" (that is, expanders) are of great benefit. The product is delivered immediately assembled. This jig has 9 fixed positions.The drill is supplied with a step drill with a hex shank.

The 2-channel oblique screw jig is, first of all, AL SKRAB 33351... Although this device is made in China, it is an exact counterpart to Kreg's products. The dimensions (thickness) of the parts to be joined are from 1 to 4.5 cm. The delivery set includes a screwdriver bit made of chrome vanadium alloy. There is also 1 wood plug.

The jig assembly can also be used to connect plywood, not just solid wood boards. First, you need to carefully measure the thickness of the structures. It is not necessary to use an accurate meter - in practice, the readings of a simple school ruler are quite enough. The dimensions are set on the jig. Then you need to immediately clamp it with a latch to exclude an arbitrary change in this parameter.

The next step is to insert a suitable drill into the jig. Then the depth gauge is precisely set. The conductor itself and the workpiece to be processed are fixed with a clamp. After that, you can already drill according to the template. That's enough to create a pair of excellent screw or self-tapping mounting holes.

The workpieces need to be connected. The most common hardware can be inserted into the holes. The fact that you need some kind of special fasteners is nothing more than a myth promoted by manufacturers. In any case, skillful work allows you to achieve a solid and neat joint. You need to plan your work very carefully.

It is imperative to take into account the course of the fibers. Holes in the parts to be joined should be laid so that the hardware is screwed across the fiber. Otherwise, the strength and reliability of the connection cannot be guaranteed. The strength also depends on the position of the retaining ring. It is tuned strictly according to the manufacturer's recommendations.

There is no need to strive to make the deepest hole possible. It is necessary to check whether the specified depth is not excessive every time before drilling. It is even better if this is done when setting up the "conductor" itself. Important: Drill correctly at the highest possible speed - increasing the number of revolutions improves the quality of the holes.

There are also such recommendations:

• spray dry lubricant to facilitate the passage of the channel;

• remove chips from the channel more often;

• choose screws for the conductor according to the hardness of the material to be joined.
