How to Glue Metal Casting to Brass
Joining or repairing metal objects can be problematic, especially when the metals are dissimilar. If the objects being joined won't be subjected to much stress, glue can be used. This method will work especially well if the point of adhesion is hidden or can be covered in some manner, so that enough glue can be employed to do the job. The key to successfully glue a metal casting to brass is using the right glue in the correct manner.

1
Take the objects being joined to a well-ventilated area. Put on a pair of disposable rubber gloves. Clean the joining surfaces of both objects thoroughly with acetone and a natural bristle brush.

2
Place the objects on a protected work surface. Allow the acetone to evaporate completely.

Examine the objects. Ensure that you know how you want them to fit together. Experiment with clamps or rubber bands to determine the best method of keeping the objects together as the epoxy sets, which will vary based on the specific size and shape of the objects.

Consult the product label of a two-part epoxy for the proper ratio of resin to hardener. Dispense the recommended portions onto a piece of cardboard or other disposable mixing tray. Mix the epoxy thoroughly with a disposable plastic applicator. Mix until the resin and hardener are completely blended and for the recommended amount of time.

Apply the epoxy to both surfaces to be joined, or as recommended by the manufacturer. Assemble the pieces. Put on the clamps or rubber bands -- or both, as needed. Employ the plastic applicator to smooth the epoxy at the joint, if necessary. Allow the object to dry completely before subjecting the joint to stress.

Tips & Warnings
Acetone is extremely flammable. Exercise caution and use only in a well-ventilated area.
Wear rubber gloves when working with epoxy compounds. Uncured epoxy can cause allergic reaction on exposed skin.
Never use acetone to clean epoxy off of your skin.
