Here is a complete recipe on how to make sodium cyanide. (Educational)
First, 100 g of sodium hydroxide is mixed with 43g of cyanuric acid and 12g of carbon. This is heated to 600 Celsius with occasional stirring for at least an hour. If the bubbling goes out of control, turn down the temperature and let it come back under control before raising it again.
After the mixture is cooled, it is broken up and dissolved in methanol. After all the large chunks are converted to a powder, 100g of sodium bicarbonate is added to convert the excess sodium hydroxide into sodium carbonate. The solution is allowed to stir for 30 minutes and then filtered.
The filtrate maybe tested for cyanide by reacting a few drops with a solution of ferrous sulfate. A deep blue color of Prussian blue indicates cyanide ions are present.
The filtrate is then dried to obtain crude sodium cyanide. Approximate yield 19g.
