Convenient Hands Free Stand for Heating
I recently obtained a couple of jars of Thompson Enamel that I want to apply to copper. I had some scrap hex steel bar and some left over square bar. I hand bent two equal length hex bar sections into brackets that were welded together to form a square frame with rounded corners. The legs were made from 1/4 inch square steel bars. It stands a little over 9 inches tall. This is a perfect height to put a torch under what ever small metal work that needs to be heated. This stand is ideal for enameling copper, brass and silver or for annealing copper alloys for hammering and shaping.
Here is the metal stand with a scrap piece of hardware cloth. This offers a porous support for heating copper sheet for shaping, fold forming, and copper enameling. Another way to utilize this versatile stand is a trivet. This is a solid metal support. If I need to heat with the oxyacetylene torch, I need something stronger than hardware cloth. That is because the intense heat from the torch can melt through and burn the wires of the hardware cloth too easily. When I need a less intense heat, like for annealing copper, I use MAPP gas torch with the wire cloth. Pictured below is the triangular trivet I made today.
I want a triangular trivet in a tripod format. The tripod shape allowed for both the maximum support and open area so I may have plenty of room to navigate my torch flame around the work to be heated. I started by measuring three triangles from some scrap 16 gauge steel sheet. Each triangle was 1 1/2 inch high and 2 and 3/4″ long.
Once I had all my triangles ready, It was time to weld them in the desired patter. I brought out my heavy duty handmade fixture. The idea was to temporarily tack weld the triangles into position like so.
The third triangle was welded instead at the vertex. Then I used the angle grinder with a cutoff wheel on the first tack weld. I was able to easily pry the newly made trivet off my welding fixture. I proceeded to grind the surface smooth for the next task this fixture will be used.
Above you will see that I added reinforcing welds to both sides to increase the integrity of the trivet fixture.
