The old saying "Cheap is Cheerful ", comes to mind.
My aim was to produce casting between 3mm to 5mm thickness but large light strong things,and not slabs of heavy soldid stuff.
The first casting required 3 Yogurt Pot fills.
Two full measures from the small section filled with water were tipped into the larger section.
Then three Heaped Table Spoonfuls of Plaster of Parish was added into the water. Once all three were heaped up into the water it was then the time to mix it with a large brush. Always add the Plaster to the water, because this avoids lumps that go instantly hard.
Each of the three layers was brushed on with a large cheap brush and not poured. Poured on it would flatten the crumpled up Cooking Foil I used as a Pattern. There was plenty of time to cover the foil and so I was in no frantic rush. Each layer was left to harden then the next was applied in the same way.
One must not over crimp the foil tight ,because the result would be spending time picking the shiny stuff out like the Old 49`ers did. Work it lightly into the shape required.
Please notice the edges of the metal foil was bent up slightly and odd things slipped underneath for added support while the work took place. in using this brush on method a thin shell casting was produced.
Casting No 1 is just over a foot long by 9 inches,and was produced from the three small Yogurt Pot measurements described.
It will dry out hard and very light and it cost a few Penny`s to produce.
I will re-use the Foil again but intend a better shape. One must learn as one travils the pathway of scratch building, and with confidence move forward to a better end.
Casting No 2
Made in the exact same way.
Turned over when hard and the foil required no great effort to remove it.
It turned out well.___

Always the object is to try and show easy ways to save time, effort and money on projects.
These simple to make castings only took 30 minutes to make including the drying hard time.
" BB`s aim was spot on this time. They being all 3mm thick."
