Ribs Clamp

Ribs Clamp

Or how I verleime places in Gitarrenkorpussen to which I do not hinkomme hand

Those like me who has glove size 11, white how difficult it is to get through a sound hole in the inside of the guitar and then to perform work there. A special delicacy are cracks in massive frames. If the crack must be repaired with a little glue and a few lateral clamps, one does not have in the interior. If you want to the defect but in the long run strengthen, wood must be resolved from within. This may create some wood veneer being which is glued with strong magnet across the gap, or individual pieces of wood (called "cleats") transversely to Zargenfaser. And now the fun begins. In order for a piece of wood defines the verify press while ensuring the flatness of the frame, you can use so-called Zargenzwingen. The trick is that a thin steel string (eg 0,09'er electric guitar string) is drawn through a small hole in the scribing area. On the carcass inside the piece of wood is pressed like pearls on a necklace strung with steel strings against the plan. The power comes here by winding the string on the outside of the frame. The exemplary service I have described in the repair area. Here I show the preparation of the Force.

Take all 3-5cm on the plan a ferrule. So with 3-4 forcing one is well served. The body consists of a block of hardwood (5x4x4cm) and a center-mounted mechanism. Depending on the available mechanism results in the width of the groove. This shall be so designed that the shaft has some space to the groove bottom; the width results from the wavelength (shaft end is approximately 4mm deep stuck in the wood).

Finished Zargenzwinge

Cleverly it, a timber with the cross section 4x4cm auszuhobeln to incorporate the groove eg with the router and stop and afterwards cut to length, the pieces only is. After drilling the shaft an opening for the steel string yet to be drilled. Depending on your taste, the location offers just below the shaft hole or just next to (besides giving a greater scope for the Saitenaufziehen and you can also string the first place several times around the shaft).

Seitenansich Plexiglas enclosure

The inner piece of wood is pressed evenly by means of a piece of plastic. Here is, for example, Plexiglas or Teflon, which ca 1,5x1,5cm measures and centrally has a 2mm hole. Use a file to almost two opposing sides. This has the sense that the piece of wood is placed in front of the bead, eg with a small strip of double-sided tape on the plastic insert parallel to the timber direction. One checks during Leimvorgangs inside the guitar body wood grain, you need only after the chamfers to keys and orient the wood accordingly.

Application principle Application principle II

Before assembling the piece of wood is sanded with sandpaper, I have the whole thing with linseed yet admitted. The underside of the clamping wood can be rubbed with a candle stub from paraffin or another type of wax, which prevents excess glue on the stick.
