Construction manual for a clamp clamp made of OSB

Screw clamps are required in every workshop, be it for fixing when machining workpieces or to achieve the required pressing force when gluing individual parts. It is often necessary that they are quickly accessible and located within reach. In drawers or cabinets screw clamps are rather impractical repealed.

If furniture is also built in the workshop, screw clamps reach a length that makes it impossible to place them in tool cabinets. Optimal and usually the only solution is the attachment to the wall. Here, a full-length screw clamp can be lifted and always at hand.

Large screw clamps usually also mean a large weight, which in case of wrong placement involves sources of accident. The construction of a clamp mount is therefore useful and creates order in the workshop.

Required materials and tools

Required tools:

  • Table saw (alternatively hand-held circular saw or jigsaw)
  • jigsaw
  • Bench drill (alternatively cordless screwdriver)
  • Router (alternative milling table)
  • clamps
  • Screws for fastening

Required material:

The construction manual of the clamp clamp refers to 22 mm thick OSB boards, Of course, it is also possible to use a different material. If necessary, dimensions must be adapted according to the material thickness.

The presented Schraubzwingenhalterung takes a total ten screw clamps on, also here may be varied. The sample photos show a holder with 11 seats.

  • 1x base plate 540 x 200 x 22 mm
  • 2x storage boards 540 x 100 x 22 mm
  • 4 x support boards triangle 90 mm x 86 mm x 22 mm
  • 4 x spacers 90 mm x 35 mm x 22 mm
  • wood glue

Step 1 - Check the given dimensions and cut

Since there are different screw clamps, it is important check the size beforehand and adjust the cut if necessary.

Check the distance of the storage boards

To consider it mainly two dimensions - the Strength of the tensioning rail (in the example 10 mm) and the Height of the movable clamping lever (in the example a maximum of 35 mm). For the test material residues can be placed at a predetermined distance of 35 mm and the screw clamp next to it. If necessary, the distance between the two grooves of the base plate, the height of the base plate and also the four intermediate pieces must be adjusted.

The cutting takes place optimally on the table saw, which guarantees straight cuts and squareness. Of course, can be helped with other saws. Since the self-made screw clamp holder contains no moving parts, slight inaccuracies can be compensated at any time by grinding or during later clamping. When using rigid and hard wood, work must be done accordingly.

The four triangular support boards can be made of two rectangles with the Dimensions 90 x 86 mm be sawed. The missing material of the cutting width does not affect the assembly and can be compensated by an edge grinding of the base plate and the lower shelf board. In this case, the different size is even advantageous.

Step 2 - Mark notches on the support board and drill

What looks rather complicated at first glance, however, can be easily implemented. All you need is scribing, a drill (bench drill or cordless screwdriver) and a jigsaw.

Drill after stop

It makes sense to use a Bench drill or a drill stand with stopbecause here only the drilling distances have to be touched. The drilling distance to the edge can be implemented very precisely and above all evenly by means of a stop.

First, determine the Centers of drilling, The distance between all holes to the front or rear is 74 mm or 26 mm. Including the hole (diameter 12 mm / 2) results later a distance of 80 mm forward. The first dimension starting from the left or right is 36 mm (30 mm + radius of the hole) and is extended by 52 mm each. The last hole should again be 36 mm from the edge. In order to avoid measurement errors, it is practical to transmit the dimensions continuously, without shifting the steel measure or the inch rule and constantly re-creating it.

For two identical storage boards, both can be drilled simultaneously, which also makes marking easier. For this, both boards must be braced or the first hole in both storage boards must be fixed by means of another 12 mm drill bit. See image.

Step 3 - Mark and saw the slots in the shelves

Simplify scribing with a drill

Saw out all slots

The holes limit the subsequent slots and can therefore be used for a simplified tear.

The used one is needed Drill bit with a diameter of 12 mm and an angle, If the drill with the shaft inserted into the existing hole, only the angle from both sides against it to be pushed and the required slot can be marked without further measurement. Red marked in the first picture.

The neckline is made with a jigsaw, which is always attached to the inside of the slot. If sawn in the center of the crack or outside, the saw blade will not flush with the hole that has already been drilled. However, small inaccuracies can subsequently be compensated by grinding.

Step 4 - Milling the required grooves

Is it just about small screw clamps with a low weight, a groove of the base plate is not necessary, However, large screw clamps bring a decent weight, which must be kept later.

For glue, especially the positive connection achieved by means of a milled groove achieves a good force transmission. Although screws can be used for bonding when gluing, but alone would not provide sufficient support.

Anyone who has a milling table, has a clear advantage and can easily determine the groove width by means of adjustable stop. Without milling table, a router with rip fence or a guide rail fastened with screw clamps must be used. This method also allows a wider cut without having to adjust the guide rail. For this purpose, the first milling takes place directly on the guide rail and a second by means of inserted spacer. If, for example, a 16 mm diameter milling cutter is used, a 6 mm round rod or an M6 threaded rod can be placed between the router and the guide rail during the second milling pass: 16 mm + 6 mm = 22 mm.

If a wooden strip with a width of 35 mm happens to be in stock or if it is made from a remnant piece, then even the second groove can be milled in the same setting.

Tip: If the four required intermediate pieces are sawn in the first step only as a 35 mm wide strip, this can be used as an intermediate layer during milling. The distance of the grooves corresponds exactly to the later intermediate pieces, which can then be divided to the length of 90 mm.

The width of the grooves should be very accurate, as this results in a better fit. It's better to cut something more closely and then finish with emery cloth. This guarantees a perfect fit and secure fit

Step 5 - Assemble and glue

By making the cuts and cutting all parts, the self-made screw clamp can be completed. Special skills are not necessary in the last step.

1. Glue in the first shelf

  1. In the first step, only one of the storage boards is glued. Which of the two does not matter. When gluing in, attention must be paid to good angularity. If the groove has been milled with a perfect fit, the storage board automatically adjusts itself at right angles. If you want to build a clamp mount, certainly has the now required screw clamps for clamping the two items.
  2. Before the second shelf is inserted, the four intermediate pieces must be placed on the already glued board. It is advisable not to use an express glue. Thus, the opportunity arises first to use the spacers and then to press the second shelf board in the groove, before all parts are clamped together.
  3. Finally, only the support boards have to be attached. Since the triangular boards can be pressed badly on the adhesive surface, in this case from the back through the base plate guided screws are helpful.
