Wood joints An overview Joining wood together Anyone who wants to make storage shelves for the cellar quickly and easily, usually reaches for the portable electric drill and the appropriate chipboard screws. But what is fine for the cellar, is really unthinkable in the living area.
The dowel joint Field of use of the round dowel The round dowel Wooden boards are most often joined with round dowels. Round dowels are normally produced from beechwood and are available in various diameters and lengths. They are inserted into a predrilled hole and obtain their stability in wood from the addition of wood glue. Therefore, the surface has small longitudinal grooves, also known as fluting, in order to achieve the maximum stability.
What you need for dowelling The dowelling toolkit Dowelling aids and accessories The Dowelmaster is the rapid dowelling tool for almost every work situation. Whether corner, t- or face joint, the precision of the joint is outstanding, and the handling is very simple. The Dowelling Jig is a real multitalent, and can be used not only for dowelling but also for drilling rows of holes. In addition, this aluminium profile is excellently suited for use as a drawing rule or guide for the jig saw.
The basics Tips and tricks Important measurements in dowelling 6 Wood thickness Dowel Ø 12 – 14 mm 6 mm 15 – 18 mm 8 mm 19 – 30 mm 10 mm The dowel diameter should be between 2/5 and 3/5 of the thickness of the wood. The table above shows the appropriate dowel diameters for the most common wood thicknesses. For corner and T-joints, the holes must be drilled no more than 2/3 of the thickness of the wood, at the most.
The Dowelmaster Corner joints The Dowelmaster 6 5 2 1 5 4 3 Wood thicknesses up to 30 mm can be joined using this dowelling aid. The board is clamped between the centring pins (1) while dowelling the face holes, ensuring that the dowel holes are always precisely in the centre of the edge. The drill is inserted into three steel bushings (2) for 6, 8 and 10 mm dowels. 2 4 The centre of the dowel is additionally shown by a mark (3) on the side of the dowelling jig.
The Dowelmaster To adjust the fence of the Dowelmaster to the dowels already drilled, loosen the fastening screw and insert the dowels into the corresponding drill bush of the Dowelmaster. T and face joints Then slide the fence firmly up against the side of the board and secure it with the fastening screw. Now the fence is precisely adjusted to the centre of the dowel and of the board.
The Universal Dowelling Jig Corner joints The Universal Dowelling Jig 5 2 3 1 4 6 The Universal Dowelling Jig consists of a drill guide (1) and a board clamp (2). The drill guide has two rows of drill bushes (3) for 6, 8 and 10 mm dowels. There is a guide groove matching each dowel size (4) in front of the bushes for holding the drilled in dowels. The board clamp does not have drill bushes, and serves only to support or clamp the boards.
The Universal Dowelling Jig T and face joints Making T joints with the Universal Dowelling Jig To make T joints, the first step is to drill face holes into the shelf bottom. Mark out the intervals of the dowels and fasten the shelf bottom to the workbench with the Universal Dowelling Jig. To drill the last dowel hole, the board clamp is again shifted from left to right. In order to be able to transfer the holes to the counter-board, the dowels must first be glued in.
The Dowelling Jig Drilling face holes The Dowelling Jig 2 3 5 1 4 5 The Dowelling Jig consists of a guide rail (1) with catch holes at intervals of 32 mm. A sliding drill head can be engaged in these holes, which is equipped with a 5, 6, 8 or 10 mm drill bush (3). This makes possible rows of dowels and holes at intervals of 32 mm. The distance of the holes from the edge of the board is determined with the angle fences (4) which are inserted under the profile.
The Dowelling Jig Corner and T joints Making corner joints with the Dowelling Jig Lay the Dowelling Jig on the side wall and slide the left side stop against the left board edge. Then fasten the Dowelling Jig to the board with screw clamps. Take care that the sliding drill head ... ... engages in the same holes of the Dowelling Jig as for the drilling of the face holes. The holes are numbered for this purpose.
The Dowelling Jig Drilling a series of holes Making face joints with the Dowelling Jig The Dowelling Jig is particularly well suited for making face joints with a high number of dowel holes. A dowel can be drilled in every 32 mm, making the joint extremely stable. The two boards are drilled one after the other with the same setting, and thus fit together perfectly.
Biscuits Field of use of biscuits Biscuits One of the best inventions in wood-working in the last 60 years is and remains the biscuit jointer. This machine was invented in 1955 by the Swiss master cabinetmaker Hermann Steiner. Biscuits are oval or elliptical 4 mm thick diagonal grain wooden plates which are inserted into a slot which has previously been routed out. In contrast to round dowels, their elliptical shape allows them to be adjusted or aligned in the 4 mm wide slot.
The multi-purpose Wood Jointer Corner joints The Multi-purpose Wood Jointer 6 2 1 5 8 4 7 3 The Multi-purpose Wood Jointer is an attachment for an angle grinder, which, after the clamping nut and wheel flange are removed, can be fastened directly into the screw opening (1). Then the lateral machine brackets (2) are fastened with the screws provided (3) to the two grips of the angle grinder. The motor of the angle grinder drives a 4 mm thick carbide tipped saw blade (4).
The multi-purpose Wood Jointer Position the side walls side-on against the clamped board and cut the biscuit slots. Then lay the top or bottom flat with the outside edge on the workbench, and cut the slot into the face of the board. T joints Side walls and floors are joined together in a moment by this method, and fit together perfectly first time. Making T joints with the Multi-purpose Wood Jointer Align the bottom precisely to the side wall using an angle, and mark the position.
Face and mitre joints The multi-purpose Wood Jointer Making face joints with the Multi-purpose Wood Jointer To join a kitchen work surface with biscuits, first mount the angle bracket supplied. Then lay the angle bracket on the visible side of the work surface and 4 or 5 biscuits are cut into the edge ... ... This makes the junction of the two boards on the upper side always absolutely flat and even.
Undercover jig Principle + fields of use The concealed screw joint The principle of this rapid, exact and highly durable joint is a diagonally drilled blind hole (pocket hole). In order to be able to make this hole precisely and without the drill going astray, a drill guide is used with a stepped drill design. The tip of the drill makes a small guide hole for the screw thread, while the second step of the drill makes a larger hole for sinking the screw head in the wood.
Undercover jig The drill guide The Undercover Jig 1 5 2 4 The Undercover Jig (1) is supplied with everything you need – apart from the power drill and a small screw clamp for clamping the drill guide to the workpiece – to create a concealed screw assembly. The matching step drill bit with depth stop (3) and the extended bit attachment (4) for conveniently screwing the joint are all included.
Undercover jig Corner, t and face joints Making a corner joint 20 Place the Undercover Jig on the board so that it butts onto the edge of the board with the stop. Fasten the board and the Undercover Jig to the workbench with a clamp and drill a diagonal pocket hole or blind hole as far as the depth stop with the stepped drill. During this, keep moving the drill slightly backwards and forwards so that the sawdust can be ejected better.
Undercover jig Mitre and frame joint Making a mitre joint Joining mitring perfectly is an art all by itself, but with the Undercover Jig, even this works first time. It is only necessary to fasten the workpieces on the workbench with a clamp in order to obtain exact and seamless mitre joints. Clamp one of the mitres together with the drill guide on the workbench. For reasons of stability, and so that the mitring does not become distorted, there should always be two holes per mitring.
Undercover jig Repairs Repairs with the Undercover Jig All repair work is done without the front stop, since it is no longer possible to take apart the wood pieces that are to be joined and work them separately. In addition, the stop can be swivelled out of the way by turning it, so that there is no longer a stop edge under the Undercover Jig. Drawers that are coming apart at the corners also do not have to be completely taken apart in order to repair them.
Conical plates Little helper – big effect The conical plates Behind the product name “conical plate” hides a small and unassuming helper that has a big effect. When you want to fill up knotholes or cover up unsightly screw holes, these thin circular plates of pinewood provide a rapid, uncomplicated solution. In addition to this, the conical plates, which can be obtained in the diameters 15, 20, 25, 30, 35 and 40 mm are also very good for numerous other applications.
