CAG do it in rubber, and resin

The Crewe area Groups May meeting took place in member Tony Montgomery delectable new home. Subject for the day was a demonstration by guest Adrian Prescott of his resign casting techniques.

Before our very eyes Adrian produced crisply cast resin parts and made the whole process look very simple and straightforward. So to prove it wasn't all smoke and mirrors he then had untrained volunteers successfully producing castings from his preprepared moulds. He gave practicable advice on what was and what was not doable in this medium all of which made a great deal of sense.

At least one member was suitably inspired to wonder if here lies the answer to the production problems related to the long trains of bogie limestone hoppers we don't have running up and down on Knustford East.

Adrian instructed us on both mould production and their use to produce the final castings, but as the rubber moulds take 24 hours to cure, practicals in mould making didn't form part of the show. This months photo (by Ron Dickinson) shows Adrian sitting in front the the minimal amount of equipment he used to so ably demonstrate his craft.

The rest of the meeting was taken up with further discussion of the production of point rodding stools from the Colin Waite etchings parts (anybody with concerns about their eyesight may need to give this one a miss) and whether the was any real practical difference between the chimneys fitted by Gorton to O4s and D9s. Oh happy days.
