Steam Department

Oh well, we are into March.  You would not have guessed it at Union yesterday as we gingerly picked our way across thickly ice encrusted roads to get between the shop and the amenity block.  The day was then somewhat shortened by the development of a steady snow storm as darkness fell.  However, there was a reasonable turn out and steady progress continued.

On 1630 it was very much “more of the same”, which is exactly what we need at this point.

Painting continued on the frames and running gear.  Christian joined the team for the first time and, by afternoon, was fitted in between the frames and top coating the cylinder casting and adjacent areas.  There is a lot of variety in the steam shop.  As a new volunteer, you cannot be sure if you will be handling a paint brush or a 20 pound hammer!.

Meanwhile Jerry worked between the frames ahead of the firebox.  So most of the lower areas of the locomotive have now received top coat and attention moved to the tender.  Jim and Jerry painted most of the tender frames during the day.  (The positioning of the bucket is unfortunate.  Honest, we are not painting it with driveway sealer!!).

There are a few more weeks of work on the lower areas of locomotive and tender that will not be obvious unless you are standing next to the locomotive.  A number of pipes and the under sides of the walkways need to be cleaned, primed and painted.  In addition there is a major review and touch up exercise.  Whenever you shine lights and look from different angles you spot areas that are not fully covered.  So there will be a significant exercise of inspection, with a brush in hand, to touch up these spots and finish the job.

Dennis had welded some areas of the cab last week and identified further areas on the fireman’s side that needed grinding out and clamping so that he could weld.  I cleaned these up so they are now ready for welding.

This weekend Dennis was cutting the new mesh sections for the smokebox spark arrestor.

Jason located another steam heat gauge, very similar to the existing one.  He was able to exchange the face of this one with the damaged face of the existing gauge so we now have a good looking gauge to fit.

Rick removed the sander discharge pipes as these would be in the way of spraying the cladding sheets of the boiler. He then wire brushed these ready for painting.

On 428:

Ed worked on the sander manifolds.  He showed me an interesting feature.  The inspection plugs of the sand channels are filled with lead.  Apparently this wears better under the force of steam driven sand than does iron or steel.  One of the plugs needs a new lead filling.

Dennis and Phil worked on one of the brake rods.

In other areas, a major milestone was reached last week on the planer.  I understand that, after much investigation and adjustment it is now effectively operational.  Critically, it was adjusted so that it now moves on the cutting stroke at an adjustable speed and then returns for the next cut at a surprising speed for such a large machine.  In addition, features that were not previously understood are now seen to operate.  For example, a small hydraulic cylinder actually lifts the cutting head at the end of the cutting stroke so that it is positively lifted above the work as the table returns.

All of this is second hand from the team as the machine was not operating this weekend.  A number of leaks were identified in operation so a couple of seals will be replaced and some connections remade to bring it to readiness for routine.

So a week of steady progress.  Now what we need is the Spring!.
