Work Holding with Sacrificial Nut and Bolt

[editor@glue-it.com]

Very simple work holding with a sacrificial nut and bolt. When silver soldering you don’t want your best engineers clamps in the path of a blow torch. Also, you don’t want the thermal mass of a large clamp.

I often have this problem and resort to a piece of wire that wraps around and is twisted tight. Or I try to balance a fire brick on top to hold it all together. The other option is to use a mechanical joint as well such as a rivet. However, sometimes these are not great options for other reasons.



Even after heating this to 650°C the bolts came apart very easily



I know this is a bit mundane, but sometimes we all need a prod to get us thinking outside of the box.
