Hornguide Machining Day 14

  Highslide JS
  Hornguide machining continues at a steady pace. Today, Luke from CTL Seal and Geoff discuss the machining of a small radius on the edge of the hornguides. Luke has the cutter in his right hand.
   
Exhaust Port Machining
09/10/2020
  Highslide JS
  Hornguide maching is now complete so the frames have been turned through 90 degrees so that they are upside down. The final job on the machine is to clean up the area where the exhaust steam manifold meets the frame so that there is a smooth transition in this area. Photo by Tom Wade
   
Hornguide Machining Day 18
12/10/2020
  Highslide JS
  The machining of the hornguides on the frames is nearly complete. We expect that the frames will be back in the machine shop on Wednesday. Today we finished cleaning up the exhaust ports on one side so Luke lifted the frames and turned them through 180 degrees so that he could get to the other side. This is half way round
   
Pony Truck Wheels cast!
15/10/2020
  Another step forward in the building of 72010, Hengist. Sam Edwards from Boro Foundry in Stourbridge, West Midlands has reported that both pony truck (or trailing truck) wheels were cast on Monday 12 October. They are left in the mould overnight before they are knocked out and then left to cool down. You can see a short video of the casting by clicking on this link.
   
Bogie Pipework Fittings
18/10/2020
  Highslide JS
  Ian (not your web site manager!) is one of our members and has a home workshop. He's kindly volunteered to manufacture the pipework fittings we need for the bogie. The original pipework design used a flared pipe end similar to that you would see on a car brake pipe. These were prone to breaking so, in the late 1950s, this was changed to a turned, coned pipe fitting secured by a nut. Here is one of the nuts being turned in Ian's lathe.
