Home for Misfit Tool (or) Rebirth of a Tinsmith Burring Machine


Recently I’ve gained an interested in the tinsmithing trade. This opened up a whole new area in tool collecting for me so I have been diligently searching tools sites and EBay for finds. During my searches I’ve come to realize that tinsmithing tools are expensive and relatively hard to find. When one does happen upon a find there’s generally a lot of competition for the tool driving up its cost. This has caused me to aim for the low hanging fruit like the rusted nugget of a burring machine pictured here.

Roughly speaking (I am no expert) a burring machine forms a small 90 degree lip on the edge of a piece of tin. This tool is especially useful when forming a lip on a circle such as on the bottom of a cup. (See picture of tin bottom)

This machine was horribly rusted and I suspect it spent a lot of time in water. After soaking in rust remover I wired brushed the metal and painted the areas black that were once coated in black japanning. The original wooden handle was shot so I turned a new one on the lathe shined up the brass and put it back together. The forming heads are pitted from rust so they tend to transfer the roughness to the tin but other than that it seem to work. Pretty good for a tool around a 150 years old.

From all I’ve read and watched on videos this is not an easy tool to use. I will need a lot of practice. But overall I am happy with the finished results.
