Sundays 20th and 27th November 2011, Carriage and Wagon Works, Bury

Sunday November 20th 2011
Attendance: 3

Today Chris, Martin and Alan were on site for an extra planning and working weekend day, the main aim to progress the air pipework further.

Martin and Alan set about completing more 8mm pipe within the brake frame area, from the brake application unit to various timing reservoirs, brake feed cut off and DSD valve. All of the 8mm work is very fiddly and time consuming so this took up the majority of their day.

Chris started on removing the old pipes from the cab manifold to the gauges and set about custom making new ones using reinforced PVC tubing and ear clips. Again this was very fiddly and time consuming work and took up the whole day.

Another batch of fiddly jobs progressing none the less, apologies but no photos from today.

Sunday November 27th 2011
Attendance: 4

Chris, Alan, Martin and Jason were on site today. Martin continued with more control 8mm pipe work in the brake frame area, Jason set about marking out and cutting out a hole in the front desk cover for the emergency valve. Chris made a repair to one of the PVC pipes that had got a nick during installation. Once done he then moved on to the 6mm pipe work under the desk which runs from the train brake E70 'joysticks' down to the brake frame. Alan made 4 new holes through the metal work next to the cab manifold for the new pipework to run through.

Jason removed the emergency valve for final fitting of the 2" pipe work and to make some gaskets for the flanges, one pipe needed drilling for a boss to be welded in so the pipe for the vac gauge could be connected. Once done the assembly was refitted to the cab and secured. Chris then set about cutting 28mm pipe for the air train pipe to run up to the emergency valve. Martin had completed the work in the brake frame area, and was now running four 8mm control pipes down to the new holes next to the cab manifold, he made up some larger 15mm pipe to go trough the holes, then reduced back to 8mm. These will be secured with gromits at a later date.

Chris connected the 6mm pipework to the 8mm control pipe using a compression adapator for each. With this complete, the air supply in the shed was connected and the pressure allowed to build up. There wasnt enough time to braze up the 28mm run of pipe to the emergency valve, so this was temporally blanked off and once the brake feed cut off 'clunked' an attempt was made to create an air train pipe. Although this part of the gauge was not connected, the control indication was, and an air train pipe was created. A buffer beam valve was opened to check, and air duly rushed out.

It was now 7pm so, with this achievement, the team packed up and headed home. This now leaves pipework outstanding for the vac chamber system, 100 PSI feed to the forward/reverse, fill solenoid valves, then on to feed the horns/wipers, 'A' end sanding valve and exhauster speed up choke.
