Inveresk Saturday 17th September 2016.
The left hand valve chest cover was removed to see whether we could remove the valve buckle and D slide valve. We believed the tail rod may have screwed into the buckle but this is not the case. We noted that the tail rod had been cut and re welded close to the buckle. Further investigation noted there could be a bronze bush in the end of the valve gland. We are making a split piece to go around the tail rod shaft to try and push this bush out.
The left hand one to one rocking lever outer and inner brackets were removed and the rocker passed through locomotive frame.
Some needle gunning of the frame has begun.
The left and right expansion link blocks were cleaned on the wire brush. These are another interesting design from Dubs, the blocks are in two halves split on the vertical axis and are held tightly together in the link by the tension on the tapered bolt.
The left and right valve levers were cleaned, one has a slight bend which will be straightened.
Sunday 18th September,
The components I have had de-rusting in molasses were removed, pressure cleaned and placed in phosphoric acid solution to when removed leaves a protective coating on the surfaces. The last drain cock lever was so treated. These components have been prime coated.
The one to one rocker shaft was cleaned using a plastic type stripping wheel which removes rust paint and dirt, There is some pitting on the inner bearing surface but not enough to be turned in a lathe.
The rocker bronze bearings were cleaned, these were found to be in very good condition.
The sand dome actuating levers were cleaned and primed, new clevis pins fitted.
Now to find a way to embed a slide show again now blogger no longer supports the previous method of insertion.

More progress with the removal of the left and right expansion links from the rocking levers by using a jacking screw and a little heat. The expansion links at first look appear to be in very good condition.
The sander valves and actuating rods were removed from the cast iron sand dome. After all these years of working in sand numerals which look like part numbers for the casting are still visible on the valves.
On the locomotive frame all we have left to remove are the trailing wheel set, the left and right D slide valves and buckles and four spring hanger pins.
We are unsure how to remove the D slide valves from the buckles as there is not enough clearance to lift the buckle and slide the valve out.
The tail rod in front of the buckle is part of the casting. It might be that the rear rod screws into the casting however most people with years of steam experience do not think this is likely. The valves must come out some how.
Parts of the old running boards and the cab footplate has been removed and will be replaced with new metal.
