Using the charango as a reference, copy the form on a sheet of plywood of 3 mm. increasing 1 cm. more taking into account to maintain an inner lining and proceed to build a template. With a band saw or keyhole, short as close to the score line and ended up with a good sanding, removing any irregularities.
With this average template proceed to make mold will consist of two separate and symmetrical that will join the final by a metal badges and some screws. The mold must be perfectamernte symmetrical and the best way is to use a hand with a shaper cutter as seen in the photos.
I used a plywood board 15 mm. thick to draw the first piece that will become a template for the rest.
The first piece of short-bound, as much as possible to the line marked in pencil through the template. Each piece (10 in total) have a width of 6 cm. This first part must be sanded thoroughly and seek to remove irregularities in the cut with the alabaster or similar tool if necessary, as it is the teacher guide the entire mold.
Once completed, under the board with this template 9 pieces, but cut to 5-6 mm. line marked with this second template.
then white carpenter glue, stick to the piece that served as template, two pieces (one for each side) so that not move after giving a hand of white glue with a brush, the one with two thin nails or nail tips without completely (once glued need to be removed). The pieces on each side of the piece must excel template that goes in the center. Then tighten adequately with 5 or 6 or Paperclip sergeants and allowed to dry 5-6 hours.
Once dressed, we proceed with the Tupi, first on one side and then the other to eliminate leftovers. Be noted that the three pieces are perfectly aligned and adjusted to the piece that made template. Finish with a good sanding.
The next step is gluing the two pieces repeating the process. With 5 pieces get stuck an approximate height of 75 mm. to be sufficient for the work you intended to do. We have become one of the sides of pan.
To the other, with 4 or 5 spikes or nails (not glue) we set another piece to the mold half already done, to make the Tupi in the template on the other side.
mechanized Once the piece is removed with a screwdriver and started to glue the pieces as we did at first.
molds When we built, joined by a metal insert on both sides with a couple of screws in each. Be made by each side a recess so that they are embedded and not disruptive.
