  1. Very impressive Andrew it looks superb. Robin
  2. To the north of Bristol Barrow Road shed and Lawrence Hill Junction there is an incline on an 1 in 60 gradient to Fishponds Station in the NE of Bristol. The gradient starts at 1 in 89 immediately under Barrow Road Arches, which is the road which bisects the shed yard. The working timetable limits the number of wagons descending this incline to 30. With this in mind I have just finished converting 15 Bachmann 16T minerals to P4 to add to some Parkside wagons to give a rake of 30. Here is a video. I will give details of the conversion later. https://youtu.be/oUMnIFhPAL8 As promised here are details of the conversion using a Bachmann 16T mineral as an example. This photo shows a completed wagon fitted with P4 wheels. It is one in the rake of wagons in the video. The principal tool used for conversion is the Knowle Wagon Works - 2mm Brass Bearing Tool. In this photo the tool is bottom left. First remove the 00 wheel sets followed by the couplings. Then remove the body by unscrewing the two self tappers on the underside. The photo shows the selection of tools and items used for the conversion. Shown are four flangeless bearings, two 26mm pin point axles plus a back to back gauge, file tweezers and a chisel knife. The Brassmasters gauge at the bottom is to ensure the axles are square and level. The first task is to remove the two ribs at the back of the W Iron using the chisel knife. You will also need to remove plastic below the ribs in order to gain width for the replacement P4 wheel sets. Next drill out the holes in the rear of the wagon W irons. This task is done using the Knowle tool. You will need to measure the width and depth of the bearings you are using and set the drill in the tool using the grub screws and the allen key. This photo shows the rear of the W Iron after the plastic has been cut away. It also shows a new bearing fitted after drilling. The Knowle Tool in position for cutting deeper bearing holes in the W Iron. The tool can be turned using fingers, a tweezer or an 8mm spanner. Once all four holes have been drilled out insert the new bearings and hold in position using the two 26mm pin point axles. If you have the depth correct the W Irons should be parallel and vertical. Use the Brassmasters gauge to set the axles ensuring they are square and parallel. Once satisfied use a dab of Butanone to fix the bearings in place. Refix the body to the chassis and fit the P4 wheels after checking the back to back using the gauge. You may need to file some material off the brake shoes to gain clearance.
  3. I hope to model Barfleur and Trafalgar but both are long fire box engines and the later Bachmann Jubilees are of the short firebox version. I will need to do some work on the model to replace the firebox. Robin
  4. Hi Michael, These are the Crankpins I have used obtained from Roxey Mouldings. I consider the crank itself, although rather good looking, to be rather overscale so I have discarded it. However I did use the crankpin itself which I have modified to take the original Bachmann crank. Robin
  5. Thanks Tim. I do have a small problem to resolve - the rivet at the expansion link/eccentric rod joint occasionally catches the connecting rod. It needs a little more clearance. Robin
  6. I have started to convert some of my Bachmann short firebox Jubilees to P4 in order to run them on my layout. This project had been stalled for a while as I pondered on the best way to do this, however a visit by Dave Holt, David Clarke and Steve Ridgeway in September gave me the necessary push to get on with it. My conversion replaces the wheels with an Alan Gibson 3mm axle set of drivers plus bogie and tender wheels. Replacement crankpins are Markits stainless steel products. The only other modification is to use a Dave Franks Stanier chassis kit on the tender. r. Here is a youtube link to a video showing Bengal moving in the shed yard. Sorry but the media link refuses to work. https://youtu.be/IzwQGyGImDw Seasons greetings to all readers of my blog. Robin
  7. Here's another at Bristol Barrow Road taken in 1965.
  8. I have just had a Digital IP replaced by DCC Concepts after it decided to stop in the wrong position - in reverse when my NCE procab was showing normal. I removed the unit and tried to reprogram all to no avail. I think a diode ceased to work preventing the motor from operating in the reverse direction. DCC Concepts have not explained what was wrong with it only that when tested it was 'dead'. The replacement has just arrived. Robin
  9. David, I appreciate your concern but the Midland did not have 'ridge tiles' on the hipped roof angles. The above photo is of the prototype Engine Shed Sidings. Robin
  10. Dave, Neither did I - I'd have called them down pipe brackets! As you say we live and learn. Robin
  11. Engine Shed Sidings signal box is now finished and has taken it's place on the layout. The box is constructed from a Churchward Models etched brass kit I picked up from Ebay, and contains a detailed interior from Springside items with armchair and signalmen from Modelu. The final items, shown in the photos, are the two downpipes which are attached using Modelu cast iron holderbats. Only the two nameboards to make. I visited the Ambis stand on Sunday and purchased a pack of etched LMS letters for the signal box nameboard. A bit of a fiddle to make but I'm pleased with the result. Individual letters were cut off the fret, cleaned up and given a coat of Halfords white primer and the board with red. When dry the letters were attached to the board using PVA.
  12. 30541 has come a long way since I took this photo of it at the back of Bristol barrow Road shed in 1965.
  13. This may be of interest regarding the Tewkesbury Brewery premises. https://www.gsia.org.uk/reprints/1980/gi198007.pdf Robin
  14. Hi John, That was good of her but I'm sure they all enjoyed your talk. Did they ask for a running session? Robin
  15. It has been a while since I did any work on the roundhouse roof so I recently added the smoke hood support wires, 4 to each hood, to the 22 that are inside the shed. The roof is entirely scratchbuilt from brass section and nickel silver wire. The smoke hoods are of two types - 3 older wooden types which are ex Midland/LMS in origin which I scratchbuilt from plasticard and brass angle, and 19 'asbestos/concrete' units which are cast in resin by my Friend Morgan from a 3D printed master. Morgan also produced the etched supports on the lower edge of the units. I have used Markits WD handrail knobs - 4 per unit - as hood anchor points for the nickel silver wire supports. Once finished I sprayed the complete roof with Halfords grey primer.
