Sand casting boxes, or containers rather I guess, made from strips of sheet aluminium and packing tape. It is a very flexible system. The stuff on the left in the last picture is a staircase to reach the top of the box for pouring.

Molten aluminium eats steel, so steel crucibles have a rather limited lifespan and eventually leak. Luckily there was not very much material in there at the time. Aluminium incident 1 was a lot more spectacular but no photography survived the event.

Take any sheet of metal. Place it on pretty much any table. Aluminium is nice outdoors as it doesn't rust.

Regular MIG welding gas such as argon or argon-CO2 mixture is rather expensive. You have to buy or rent a bottle and the gas itself isn't exactly cheap. CO2 fire extinguishers however can be had for next to nothing at a junk yard. Just make sure there's still some in it. You will now be MAG welding which works fine for regular steels, but not for aluminium. You will need to make some slight

7018 are really nice welding electrodes. They can however be a bit difficult to ignite. That is until you understand what's happening. As a lit electrode goes out there forms around the tip a ball of non-conductive flux. All you need to do is remove this with a file and you're good to go. I can't claim to have invented this method but I'll include it for anyone learning to stick weld 7018.

The upper unit is for use in a system where slow burning over a long time is preferred. The idea is to put it in the lower part of a furnace where it allows embers to pile up allowing one to add some wood every now and then without restarting the fire. The lower image shows an ash removal device.

High frequency welding is used for joining PVC foils. Two or more foils are placed on the welders table and an electrode is fitted in the machine. Adjustments are made to apply pressure evenly over the electrode and finally a current is fed through the pressurized electrode. I used this method in a number of sculpture projects and became quite comfortable with it. While working with the HF welder

For melting around 6 liters of tin, lead or aluminium. The part wrapped in aluminium foil is also lightweight concrete blocks. The inner walls are thin sheet steel, I think 0,7 mm. This furnace heats up pretty quick. The blocks are supposed to last longer if you keep them dry, I guess especially during the winter. If you're melting aluminium, make sure pieces that go in are absolutely dry and

Instructions: Reverse one of the exhale membranes and fit it with a 1" vacuum cleaner hose, preferably one that's not previously been used for vacuum cleaning. Block the original port for entering air with a suitable plug.

Cheap tools like these angle grinders often come with short stiff plastic cables which are okay as long as they're indoors, warm and close to a socket. Replacing them with longer flexible rubber cables is quite easy and really nice.

I was working with some sculptures with a graphic representation of a type of wicker known as danish cord. An early small scale attempt involved flexo printing and an ink filled roller device. The final solution was much more simple, a stencil mounted in a frame. Screen printing ink was then applied with a roller.
