The moulds were semi dried in the sun for a few hour, then the moulded shoe could be removed from the mould to be pressed. Note the upturned car jack to do this job.

‘A big double press for pressing the rubber in moulds and slabs was manufactured out of two car jacks and some heavy timber.’

‘On 31st December 1942, Captain Albert Symonds was sent back to Changi …. where he was appointed to be in charge of the camp workshops.
In a community the size of Changi, as a need arose, someone was found with the knowledge or ability to produce what was required … rubber sandals, rope, nails, the list was endless and it included making coffins.
He continued to run the workshops for the duration of his captivity, at the heart of an enterprise which saw prisoners employing remarkable ingenuity to fashion everyday but, nonetheless, vital objects from the most basic materials.
We acquired barrack room lockers … which we cut, shaped and welded into dixies, mugs, baking trays, buckets and pails. We produced toothbrushes and brooms using the same palm fronds that we used for attap. Clogs were mad from motor tyres and from soft rubber wood, and with the latex from the rubber trees we repaired boots and shoes.
When in 1944, the Japanese gave the order that all prisoners were to move to the confines of Changi jail, the workshops were quickly dismantled and relocated and continued to produce a steady stream of much needed equipment, those in the workshops providing much of the labour and ingenuity which went into making the jail more habitable.’
