Plan A, I cast up the moulds but the castings produced broke into several pieces.
A classic sample test of misfortune,that I thought might happen, but after shoving the results into the waste bin, plan B came into play.
Duly entered in the Log.
Never mind BB. Ride on ,ride on to the end of the rainbow.... sang out the cowboy who always sleeps in his boots.
yes the sun will rise upon another much better English, slap dash dawn.
Said the little Button who never speaks in capital letters.
Cheap Styrene Sheet was glued into place on the top and bottom and scribed out using a cheap black pen. Hopefully these will look quite old upon the first colourwash dipping?
This double sided re-configuration is now very tough indeed.
There is a gap showing at the bottom so...…..
….. a spacer card was inserted into the box to make it the right size for the pattern to be slid into place.
The box was turned over this makes it easier to smooth over flat with the hand. Everything is brushed with baby oil including the moulding box.
The box was filled with my rubber mixture and the pattern pushed into the soft stuff up to its halfway point then smoothed over. Guidance pin holes were made with a brush handle.
More bricks added built up the moulding box.
After 20 minutes everything was oiled up, and the top half of the mould was filled.
Stuff left over was not waisted but used to mould ancient Greek & Roman stone columns.
When the rubber had cured the whole thing was simply pushed through and out of the box.
The two part mould which is wide open on two sides needs the flash cut off, and washed in soapy water. Then it will be ready for the first sample casting to be poured.
And so it happened to be the case on the following day,`Bank Holiday Monday', that both the ancient stone columns and the main mould were filled. Pouring it into the rubber block mould assisted by height and natural gravity sent the plaster of Paris into the middle of the mould forcing the air to escape as it rose up the two side cavities.
A thick elastic band around backing boards is just tight enough but not to tight. With this type of rubber band around the block mould, I like to be able to flex away both parts of the mould with my thumbs and upon release see it spring back into place. So tight enough to stand up to the pressure involved with the pouring of this tiny item.
A flat faced styrene card was also pinned onto the bottom which can be seen in the photograph. The dress makers pins were pushed in at differing angles making this seal very strong indeed.
These were slipped in here as all were cast up on the same day.
Percy who happens to be HO OO railway scale takes a stroll along the window sill. He`s looking for his cottage but it seems someone or something has half inched it.
Ad it away, Pinched it.
As they dry out after colourwash dipping,
i they certainly do look very medieval monastic old.
there will also be a plan c conversion later.
Yes a little later. BB
