Instructions for using Bendalloy
1. Clean tubing to eliminate dust, dirt, swarf etc.,
2. Anneal tubing
3. Plug or crimp one end of tubing.
4. Insert in hot water tank with open end above water.
5. Fill with MINERAL oil not vegetable etc.,
6. Empty oil from tube.
7. Hold tube at an angle say 30 Deg. And slowly pour in molten alloy. Always melt the alloy suspended in hot water using a ladle or similar.
8. Place filled tube in cold water. Allow 15 to 30 mins for cooling depending on dia. Of tube.
9. Remove tube from cold water and stand until room temp is reached.
10. Perform bending operation smoothly and slowly.
11. Insert tube in hot water and drain out alloy.
12. Take empty tube and plunge into cold water.
13. Use a “pull through” to remove droplets.
14. Clean tube to remove oil film.

BENDALLOY
Also known as cerrobend and pewtalloy. Can be used for casting or inlay work. It is a low temp melt allow, the melting point being around the temperature of boiling water, 70 degs C.
POWDERED METALS
Aluminium, brass, bronze, copper, iron and old silver are powders that are available. They can be mixed with any two part cold cast resin/hardener. When hardened they can be cut back with wire wool and polished with metal polish. When finished it looks just like the real metal. In some instances, brackets etc., can be cast from these metals.
DYES
Opaque and translucent dyes in various colours are available for cold casting as above, also inlay work. When using black for example the figures that are said to be “made from coal” can be cast. Also used for inlay work by turners and carvers.
