  1. Yes!. Pre-grouping railways used loose heel switches and there is a visible kink in the open switch/closure rail. I drill a hole in the end of the blade then make a fishplate from a length of wire bent double and soldered to both sides of the closure rail. I file a flat on one side of the wire so that it sits further under the head of the rail to clear the passing flanges. Regards Roger

    Which side of the slip is only half there. It would seem that you need a double slip. One slip is for access to the sidings from the head shunt and the other for the run round. Regards Roger
  3. Do you mean caustic soda which is sodium hydroxide or do you mean washing soda which is sodium carbonate? Sodium hydroxide reacts with metals such as aluminium, zinc, tin and lead (and copper when hot) producing hydrogen. It also corrodes skin and turns the skin oils into soap. Regards Roger
  4. It looks to be in photographic grey so I wonder if it ever went into service looking like that. If it was just a works photograph why have they used it as a billboard even for GNR posters? Regards Roger
  5. What do you use for chemical blackening and do you have any tips on how to use whatever it is? Regards Roger
  6. Hi Tom, Can you tell me what size the bricks are and hat the item number is for Flemish bond? Regards Roger
  7. The Great Eastern where using 30ft rails with 11 sleepers per length. In about 1904 the number of sleepers to a rail was increased to 13 because of the heavier Clauds coming into service. There is a thread on templot which gives much more information. http://www:85a.co.uk/forum/view_topic.php?id=965&forum_id=1 Regards Roger
  8. Would it be possible to design and store a bell crank to use with the under baseboard tie-bar (item 1-100). Ideally it would need a firm pivot which could be screwed down and be adjustable and able to reduce the from 10mm or more to approx 1.5mm. I think the materials used for the tie-bar (1-100) might be ideal but I have no experience of this sort of design. Regards Roger
  9. Thanks Jerry ~ just what I wanted to know! I wonder if Edward Sissling stocks them. Roger
  10. How does the "bench plate" fix to the bench? Does it need to have a recess cut in the bench or is it a clamp on device. I need one to fix to the kitchen table without upsetting anyone.
  11. You could use a crank with unequal arms. Mount the magnet on the long arm and drive the shorter arm. Alternately a lever pivoted at one end, the magnet at the other and driven say 25% of the distance from pivot to magnet. This would increase the movement fourfold but with a loss of force to move the magnet. Roger
  12. Thanks for the offer Don but I have a lifetime supply of new lead offcuts from some roof repairs. However I asked about copper tungsten as I am struggling to add enough weight. Regards Roger
  13. Thank you for the suggestion. Unfortunately the product they sell is some form of cloth presumably loaded with tungsten powder. I measured the density and it was about 5.3 gm/cc about half that of lead and about 3/8ths of pure tungsten. Regards Roger
  14. Does anyone know of a supplier or other source of copper tungsten sheet for adding wieght to a loco? Roger
