Pan Handle Clamp

Original frying pan

One day, my daughter informed me that she wanted to throw a frying pan away because she did not want to use it. The pan itself was made of aluminium alloy and the handle was made of plastic.

That started me thinking. What could I do with it? It seemed such a waste to throw it away.

Well, I had wanted a spade for my gardening, particularly to scoop up materials from my compost heap. As it was, the frying pan would not be a very good spade. I needed to do some modification on it because a spade had to be attached to a long handle in order for me to carry the scooped earth materials with my two hands.

The way the pan was constructed made it not strong enough to carry the weight of a full scoop of earth or compost material. What I needed was to attach the pan to the long handle.

I opted for functionality rather than for visual correctness. I decided to just drill two holes on the pan face for a U-bolt and then tighten it up against a long wooden handle. In this way, the pan was strongly attached to the wooden handle and could take any load as a spade. To make the shape of the pan more like a spade, I hammered the front of the pan against some sandy earth to flatten it as smoothly as I could, much like what a blacksmith would do on his anvil, except this was done at normal temperatures. Anyway it was soft aluminium alloy and not steel.

Next came the handle. I had a perfect modification plan for it. Because of its naturally curved shape, I wanted to convert it into a clamp bar for my diy movable gantry cnc machine. Currently, I had been constantly replacing some of the clamps that I had made before.

The initial ones made of hardwood had already been broken off one by one and were no more in use. Now, I had some made of phenolic pieces, but I found that these too had also gradually been broken off one by one.

This pan handle seemed to be perfect. It was stiff but at the same time tough and slightly flexible. It seemed to be made of some sort of thermoplastic material, maybe HDPE. I will see how it performs.

Welding Machine Stand from Video Boom

Previously, I had made a video camera boom stand using the base of a stand fan. It could be moved around easily at my workshop because I had fitted castor wheels on it. Now, I had a need to use my welding machine in my workshop, so I decided to make use of the same stand for this purpose. This was modeled after another version that I had made in my previous house, of which I was not able to bring along with me to my new house.

I had to fabricate a piece of plywood for supporting the welding machine. The plywood was fitted with a means to secure it to the vertical spindle of the stand. The height adjusting mechanism was already a built-in feature when it was functioning as a stand fan.

The reason for me to use the welding machine stand was because the welding machine came with quite short lengths of welding cables. These cables were the electrode holder cable and the earth cable. They were thick cables so that they could carry high currents during the welding process. Probably to keep the price low, the manufacturer had opted to supply the machine with short lengths of these thick cables. The welding machine itself was powered by a mains 230 Volt 13 Ampere wired plug.

So, if there was any welding to be done at site, the welding machine could be brought into position near to the work piece by using a normal mains extension wire. However, because of the short welding cables, the welding machine itself had to be brought near to the work piece. This was when the height-adjustable stand became useful. This was especially so if the work piece was higher than ground level. The stand enabled it to reach higher. For my workbench, it was ideal for welding. Because the welding machine was placed on a stand which was separated from the workbench, more space was available for the actual welding work.

The video shows the setting up of the welding machine stand.
