Of all the devices that are dominated by percussion instruments, metallic percussion group that most species other than the only one xylophone ¬ atunya in the percussion group. thus making of gamelan is largely focused on the process of formation of the metal to be used as Gamelan, by way of mencapur some kind of metal in the appropriate dose to obtain a rounded sound and sonority. The word "gamelan" in the language wawa or in other words "gangsa" which means a mixture of copper metal and Rejasa, or also mean mixing formula both of these metals in the ratio of three (3) and Sedasa (10), which bertati 3 to size tin and 10 to measure. Copper. dose ratio between copper and tin should be right once, and the professor's own Gamelan which will examine and measure in order to obtain a pure mixture of the so-called Bronze. entire process of making Gamelan is divided into 5 phases: 1. Membesot: fused mixture2. Menyingi: print 3. Forge: beat by using a form with recov ¬ particular kul. 4. Unfurl: final completion ( finishing ) 5. Melaras: adjusting tones ( tuning ) 1).Membesot At time 4 this clever bride ¬ Gamelan forge glue, then the professor or in the sequence prepared in advance so-called "kowi" is shaped bowl made of clay mixed with rice hulls in the traditional way is still used to this day. It also prepared "Prapen" or where the fireplace is equipped with a "Lamus" or tool to blow the wind in order to obtain a temperature hot enough. kowi that is so then filled with a mixture of the metal and thus Prapen heated above 3000 ° C, so into a kind of porridge iron becomes whitish and Bronze material called " GASA ". material that would perfectly Gasa shiny black and if not so then this material is melted again with former given additional filings and bran that will clean the dirt-dirt ¬ not required. kowi used also vary according to the volume number of the metal to be mixed, so one smelter with a maximum content of a 2000 cc can form one or several blades Gamelan.
Various forms kowi
2). Menyingi
Prints Menyingi or molten metal is the second phase that will shape the blade or round with three print is:
1. Dawan shape or elliptical shapes that will form the blades.
2. Round shape with half the volume of a sphere for the manufacture pencon.
3. Pasinngen form or Cebongan (Rerudu)
From printed forms are then poured molten Gasa processed later to more clearly established.
3). Forge
The process for the formation of Gasa then is to forge a form intended. Farrier in the manufacture gamelan called intelligent (Pande) led by a Clever The master with a total of 4 people with 4 different types of hammers are large.
Hammer that is used with the names, the smallest is the "Hammer Ngajeng" held by Clever named "Wirun" hammer kamudian more big-called "Middle Palu" by "Handaga" bigger hammer was called "Hammer Clamps "held by the largest Kartala and hammer called" Hammer powder "held by Brajanta.
This is done with a metal penggemblengan 4 continuous rhythm until Gasa be thin. This process will stop penggemblengan consecutive starts by Brajanata then the tune of "Three" and until the last stop Kartala just stay Wirun are still galvanize.
Gasa metal that was beginning to form later perfected by The master came to form an occasional Gasa enter into the furnace, which is when it's red to be done forging new again.
Meanwhile artisan "Lamus" assistants who serve the blowing wind will stay up lamus The master signal for wind speed or vice versa.
Various specialized forging equipment for the manufacture of Gamelan
For the manufacture of circular instruments with pencon like Kenong, Gong or Kempul; mobilization was done on printing result, saucer-shaped, forged from the inside out to be a form of inequality.
The process then once it gets to the intended diameter formed on the curved edges with a certain punch and hammer. The shape is still visible traces of blows on Gong and kempul aside part Pencon mashed up shiny.
At time 4 this clever Gamelan forge slab, then the professor or in the sequence is called Flag Sepuh charge of directing the fourth Clever with a long iron bar that holds the hook-shaped end called "Penyukat"; by rotating and moving the slab Gasa in the right position.
The most difficult phase is the time to make Pencon forging and folding the edge of a Gong. By using various hammers specifically for this purpose, Flag Ageng make movements with a hammer like motion so that a fringe memacul, rolling slab Gasa.
As for making Pencon well with all kinds of ways, among which hit the middle of plates Gasa to hammer the end of it round the egg, to obtain the intended design Pencon, and other ways that are not commonly used is to put plates Gasa on the rocks with a hole the size of Pencon and then hit him in the flat which is situated above the gravel pit.
Various forms of hammers, Gauges and heat retaining curtains
At the time of making such blades for when Sharon, the form of printouts for compacted while establishing forged blades intended.
There are a number of cross-section of the bar with the style of each such blades ¬ Mataram or any other form.
Cross-sectional shape of the bar is used for Blade Gender jugs, but on Gender typically use a form of "Kruwengan".
From when the forms ¬ Strip to obtain further propagate the result of a combination of several styles, such as the form of "Jayabaya" form "Siyem" wake up "Mojopahit" and up "put up".
This building forms that are evolving continuously combined with a variation of the original building style Gamelan each maker. Results for forging blades in general have a size set by master masingzmasing Gamelan, but in general these blades have the size:

However, these measures may change depending on the final results after the "barrel" or "tuning", so the comparison does not match with the term thick volume; thus may be filed and the length of the bar is adjusted to the pitch in question.
4). Unfurl
The next phase in the manufacturing sequence is gamelan unfurl or settle the final round or in the foreign language "finishing". In these standard forms of gamelan has so but still with a rough surface. Therefore, in further employment is the solution to hone and refine the surface-surface very carefully, so as not to change the tone too much.
In this hone job dalarn first with coarse rasp, then with fine scotch and last with fine emery paper until the surface becomes shiny.
The blade-blade Sharon, Gender, Slenthem then on Kenong, Tap and Bonang and his group, all the instruments are chopped up surface glow. Only on the Great Gong Gong Agung or polished pengkilat usually only on Penconnya only, whereas in other perrnulaan left with the original color of dark colored ¬.
The process of forming a skewed Gong Gong and refined.
Massage is a way to do the finishing work:
1. Filing with the miserly rough
2. Filing with smooth miser
3. Filing (rubbing) with fine sand.
4. Refine pataran
5. Rubbing with a pumice stone to strip sketch so horribly mean
6. Rubbing the grindstone for so horribly rid outline former pumice
7. Rubbing with coal to manufacture container sketch grindstone
8. Rubbing with brick powder
9. Rub with liniment or polish that at this time many sold
The term for this to work rubbing certain parts that have pencu Gamelan is:
a. Pencunya a glow called Gambang Repetang.
b. Pencu and Rai: Field moon
c. Adera, Rai, Recep till I called Review
d. Entirely glazed called Gilapan.
