    As many may know, I will be casting my own white metal parts as part of my Highlander Models production process. I've just had a brand new mould delivered for class 26 and 27 bogie furniture and the development casts that came with them were ok.

    Two of the parts that are available from the mould are composite suspension parts which ..... whilst they cast fine, due to their rather fragile dimensions, are a little susceptible to breaking. They wont necessarily break as a matter of course but they do have the potential to break if not handled carefully.

    Now .... I thought ...... bother, I can see this being a potential issue further down the line but .... not necessarily as there are various types of white metal with differing composite make ups.

    There are a few elements that go into making up the finished " white metal " the over arching name I am taking as being a generic description. Change the mix ( or compound make up ) and the properties will change with it. Add a bit more of one type of ingredient and it will make the finished product more malible or brittle or harder or softer ........ you get my meaning.

    So ...... as well as the learning curve I have with the production of " kits " per se ........ I need to consider what compounds are best for what application.

    One man's food ...... is another mans poison as they say. Am I glad that I studied properties of materials as part of my university degree. At the time , I could not quite work out why I was having to study the properties of metals, concrete and God knows what else in order to become a commercial quantity surveyor ......... thank God I did. :avatar:

    More on the experimenting with different grades of white metal ingots as it happens.

    Cheers

    You could place some 0.5mm wire in the mould where the break might occure as reinforcement. All white metals will perform the same with that thickness.

    Not necessarily Steve. Their characteristics change and Dan make all the difference even at the given thickness. Maybe not a huge difference but non the less..... you cant change the laws of physics. :avatar:
