gadget Posted October 14, 2019 Share Posted October 14, 2019 A friend of my wife has a casting of jesus on a cross that was broken into three pieces. I believe this is an heirloom. Here are some photos. I'm hoping to get some advice of the best process from putting it back together. I'd hate to just epoxy it. It isn't ferrous (not magnetic). I imagine the melting temp is pretty low. Should I try to braze or solder it? What flux or type of prep work would be the best? Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted October 14, 2019 Share Posted October 14, 2019 I would be afraid of using any heat on it not knowing what metal it is cast from. If you do a low temp solder may work. Quote Link to comment Share on other sites More sharing options...
SLAG Posted October 14, 2019 Share Posted October 14, 2019 If epoxy resin is not advisable. Have you considered crazy-glue? (cyano acrylic acid) SLAG. The corpus on crucifixes are frequently made from pot metal. And many of such castings are made from metal that has a very low melting point. Please be careful with that religious item. SLAG.

Glenn Posted October 14, 2019 Share Posted October 14, 2019 You may want to make a casting mold of the object before you start. Call it plan B. As others suggest glue would be preferred to heat on an unknown material. Quote Link to comment Share on other sites More sharing options...
BIGGUNDOCTOR Posted October 14, 2019 Share Posted October 14, 2019 If it is a colored pot metal (looks brass colored on my monitor) any heat will affect the color. If it is a zinc based alloy , there are some low temp aluminum brazing rods that will work with a propane torch. Brownell's gunsmithing supplies has a low temp solder called Force 44 that melts in the 400F range. If it was me, I would consider epoxy with a wire inset as a reinforcement. Keep it simple.

gadget Posted October 15, 2019 Author Share Posted October 15, 2019 wow, all great ideas...thank you! I really wanted to stay away from glues (it kinda of seems like cheating) but as you all mention, not know the metal composition makes using any heat pretty risky. Glenn, I think you're right. Making a mold will be my first step. Doing it right might take a lot more time but at least I'll be working over a "safety net". I agree that epoxy is probably the best route...I'm pretty sure it was broken by a child so I doubt it will be allowed to happen again.
