Phase 1

I thought this would be enough for my needs I have now added an Induction Furnace, this little baby is still good to melt aluminium and is making good work of melting the can's from the local pub into usable stock.

 

The Furnace

First I rolled a large steel cylinder, then  cast the first liner using insulation material.

I then cast the main fire compartment with supports for the crucible which holds 10 litres of molten metal!

Another steel ring was made and cast with refractory and insulation material to make the lid. This lid has a large hole in the top which allows access to the crucible for filling. I then cast a reducer plug to reduce oxidation.

The Rig is mounted by bearing blocks on a steel frame, and a 40/1 reduction gearbox is used to control tilt.

An adapted oil-fired central heating burner provides the heat.

 

The Mulling Machine

This machine has been constructed to mix the sand and clay to a fine breadcrumb consistency.

The first casting went well the aluminium melted quickly but there are issues with the dampness of the sand and the positioning of the sand box.  Needless to say the sand box is going to be constructed from steel and be on wheels for easy manoeuvrability.

Pictures of the Second-ish Casting

This is the fourth casting. After the first, I did some experimentation with wax casts formed from a rubber/latex moulds. My reason for this is I plan on casting each item more than once so a rubber mould will enable me to do multiple copies.

The aim of this particular casting was to form a cylinder of aluminium which then be turned to form the back wheels of an electric train I am currently making for my two train mad sons.

The aluminium cylinder is almost exclusively beer cans!
