Hi, I've been playing around with the attached 4-SF double slip. Initially I thought it was OK. However I think that there is something wrong with the switch blades. Can somebody have a look and tell me what the problem is. Even better I would be very grateful if somebody could fix it for me. Many thanks Charles |

Charles Orr wrote: I've been playing around with the attached 4-SF double slip.Hi Charles, Looks good to me. I notice that you have sensibly opted for switch-diamond K-crossings on a curved 1:7 slip. 2_201325_320000000.png  There was a redundant turnout template in your .box file which I have removed. Also I moved the half-diamonds up to the start of the box list order. This allows the switches to be drawn over the top of them on the printed output, which makes the switch rail edges appear correctly. This is probably the point you were making about the switches? I also removed the track centre-lines from the overlaid templates, as they are unlikely to be needed and simply clutter the print. .box file below. regards, Martin. |

Hi Martin, Thank you very much for that. I should have remembered about the template stacking order but I did remember what you said before about switched K crossings.  Best regards Charles |

Hi Martin, A question about groups. Now that I have got a viable slip, I would like to use it in a layout design. I have successfully added the file to my layout project file. I have grouped all the partial templates in the slip and moved it to where I want to attach it. My question is how do I move the whole slip and peg it onto the notch? I only seem to be able to copy one partial tempate to the control and then peg that on the notch. Many thanks Charles |

Charles Orr wrote:My question is how do I move the whole slip and peg it onto the notch?Hi Charles, First select the entire double slip as a group of templates. Do that first. Then on the template within it where you want to make the join, move the fixing peg to the required position, and put the notch under it, by clicking this: 2_120821_000000000.png  You will then see an option to link the group to subsequent notch moves. You can then shift the group to wherever you want it by putting the notch under the peg at the required destination. i.e. repeat the above on the destination template (which is not a member of the group). If it ends up facing the wrong way, click the group > rotate group 180 degrees menu item. Remember to unlink the group afterwards. More info about all this here: http://templot.com/martweb/gs_geometry.htm#shift_group_notch Sorry that page is 10 years old. Some details may be out of date. Ask again if it's not clear. regards, Martin. |

Hi, Having now built a test double slip, I now need some advice on gapping and rocking cranks. Firstly can anyone point me to a diagram which shows how to correctly gap a double slip built on copper clad timbers? I am using DCC. Secondly, Martin mentioned the use of a rocking crank to drive the switched K crossings. Can anybody point me to a diagram that describes such a rocking crank? I will be using a servo to drive it . Many thanks Charles |

Charles Orr wrote: Hi,In response to your first question, "where to gap" I have on some pages of my web site how to wire up some types of "points" http://www.stciers.me.uk/home/track_wiring/id_slip.htm will take you to the inside slip page. It shows the electrical sections that the formation needs to be split into and how they are then connected dependent on the switch settings. If you have subsequent questions please ask. Cheers for now John from 33820 St Ciers sur Gironde |

Hi Charles, Here is the gapping for copper-clad and rails for a slip. Single and double slips are the same. 2_270617_360000000.png  The switching is exactly the same as a turnout. You just need to know that the polarity of a V-crossing at one end is switched by the movement of the point blades at the opposite end. For a double slip, all the point blades at one end move together. Either physically by being on linked stretcher bars, or by having two separate point motors connected together. Movement of the K-crossing blades does not switch anything, the gapping and wiring is exactly the same for fixed or movable K-crossings. Make sure when centre gapping copper-clad for a slip that the gaps between the blade tips are wide enough that each blade when open does not contact the opposite side of the gap. regards, Martin. |

Hi, I know that this has been asked before on Templot Club but I have not yet found a straightforward answer. I am currently building a double slip and seek advice on the order of build. I have built many turnouts and always start with the common crossing and check rails, building outwards. I have had no problems using this method. Consequently I have started the double slip with the two common crossings and check rails. What should I put in next? My slip has switchable K crossings. Clearly I need to gauge off certain parts . Bearing in mind that I have already done the common crossings, how to proceed to get the best result? Any advice gratefully received. Best regards Charles |

Hi Stephen, Many thanks for that. I was at the East Midlands show yesterday and had the good fortune to chat to Tony Wilkins on the Scalefour stand. There was a double slip on display and we went through the basics of the construction sequence which was much the same as you describe. I attach a picture. This particular slip does not have switchable K crossings but it has given me some other ideas on how to build mine in 4-SF Best regards Charles |

Try attaching it again, or maybe it would be better to upload it to the Image Gallery at: http://85a.co.uk/forum/gallery_upload.php#gallery_top regards, Martin. |
