As my "DOT" project is only moving at snail pace at the moment and I have no other steam related stuff ,I thought some of you might like these pictures of my own model making.Its a bit different from model engineering but uses most of the techniques. I apologise for the quality of some of the photos , but they looked fine on the camera ! Abby. die  banjo  die2  heads  bulldog  geofsdog  fish  dogs  |

Beautiful work Abby, can you satisfy my curiosity?
What is the green core material in the banjo die? - the steel cores I think I recognise.
The set up in the picture titled die2 is interesting, can you explain the materials and usage, is the main cavity open backed?
I cast often mainly lost wax but some delft clay, primarily in silver and gold - always fascinated in new (to me) techniques especially from fields other than jewellery where we tend to be a bit stuck in our ways, besides, got to do something with all this brass and bronze swarf!
Cheers
Andy

Andrew the green stuff is soft silicone rubber, after injecting the wax the steel pieces come apart and the rubber pulls easily from inside the wax pattern thus saving on machining.
die2 is made from "chemical metal" in brass backing pieces , in practice the wax patterns release easily from the die and are very accurate in size and quick to produce.
Both dies were produced more as experiments than anything else as I tend to pour most of my waxes.
Abby.

Lovely to see your models and description of the materials used, this is a great site for sharing experiences, which could never be done through the model mags.
The almost instant photo taking, down loading, and description writing, taking up little of our presious time, compaired with months of wait to see if an article has been accepted and eventually published.
Well done.
David.
