After some months of silence here a new report from the DSSG. There are some projects we are working on and that are making progress.
A small project was the rebuilt of a finescale GWR 0-6-0 saddle tank to the S7 standards. The kit was not designed for S7 standards so we had to change the measurement of the splashers on the footplate. We turned wheels into the S7 standard and replaced the first and third axle with a S7 axle and modified the power pickups. The middle axle with the inside motion was reused and we used Slaters’ filler rings to get the correct S7 back to back measurement. After this rebuild the engine was converted to DCC with a Lenz DCC decoder. A challenge was to make the CPL GWR loco lights working. With a small SMD led fitted into the small brass CPL casting we got a working loco light. For this fine work you need to work with a magnifier to solder the small thin wires on to the 1mm x 1,2mm x 2mm SMD led. The CPL loco lights are relatively simple to convert into a working light.

In the GWR 0-6-0 Dean Goods Cor installed an ESU sound decoder with ESU power pack and speakers. After an experiment to find out what the best place will be for the location of the speakers we came to the conclusion that the best place is one speaker in the smoke box and one speaker between the frame plates. Important is a open chimney so you can hear the exhaust sound through the chimney. There is no speaker in the tender. In the tender we mounted the sound decoder and the power pack. The connection to the engine is made with an small 22 pins connector so the tender and engine can be separated very easily. For the synchronisation of the movement from the inside motion with the exhaust sound we will place 4 very small magnets in the big tooth wheel which is mounted on the axle in the ABC gearbox. An electronic Hall censor will pick up the change of the magnetic field and give synchronisation signals to the ESU sound decoder. For the sound we chose the SWD Pannier sound. There is no sound for a GWR 0-6-0 Dean Goods available. At the GOG 2012 Summer show in
Halifax and Cor spoke to an expert in DCC sounds and he told us the Pannier sound is the most nearby and so suitable as a Dean Goods sound. Arnold
