The old masters of carpentry there is a very handy versatile tool, which is to remind home to craftsmen working with wood. The device is called Vama. It is an indispensable tool when you need to glue the frame to make a panel of boards, assemble with glue so-called furniture of boards.
Vama itself is extremely simple. This is usually a wooden block or a thick rail with one hand which made a lot of cuts-grooves and over the entire length of the longitudinal guide slot, disappearing under attached to the end of a boss-stop. Is moved along the guide boss slider with the protrusion in the groove and the metal frame of the stirrup rod with a diameter of not less than 3 mm. That’s the whole design. To use it you still need to prepare some wooden wedges. Depending on future work can be done several such devices required sizes (in the drawings they are not shown).
