Lybster HR53 Recent Progress

Lybster HR53 ready for a run at the CD0GG Running Day

The sheet-metal work of the superstructure is nearly complete now though it's been a case of one step forward and two steps back recently as the shape of the cab cut-out is still not right and needs to be carefully re-shaped to capture the character of the prototype. Before I took the engine to Carlisle to the club running day today I cleaned the wheels, which were starting to show signs of rust, due I'm sure to fumes from the flux I'm using, I'm tempted to return to "Fluxite" though the greasy nature of this is in turn a cause for concern, it being difficult to eliminate entirely .

Lybster's previous outing on the club layout revealed a problem which hadn't showed up at home on my test track. Each time the engine passed a particular place on the layout she faltered slightly, or at slow speeds stopped entirely! Opinion leaned towards a short caused by the bogie wheels coming into contact with the splashers and indeed it proved that this was indeed the case when I experimented back at home...too much play on the wheels. A simple slim washer remedied the situation. Today on the club layout she ran smoothly past the place which had so recently proved her nemesis and, despite carrying little weight as yet, she made light work of a dozen chunky wagons.  

Lybster HR53 superstructure progressing well though the shape of the cab opening remains to be refined.  

One of the benefits of being a member of a club is the expertise among the members that can be called on to help a project along; both chimney and dome in this case were turned for me by club members with more engineering skill than myself. I drilled the dome for the safety valves which are mounted on top, these are short lengths of tube to which washers will be soldered to form the upper rim. It is my intention to use rivets from the "Archer Surface Detail" range of relief transfers to represent the circle of rivets on the rear of the smokebox and indeed in several other locations around the engine including the long row of rivets along the tank tops that hold the outer casing that bridges the boiler in place. I've done a little experimenting with Archer's relief transfers and I think they're robust enough for the job as well as looking the part.
The brake cylinder is in place beneath the cab and so is the transverse brake cross shaft, there's a good deal more detail to make in this area.
I'm working on a master pattern for the tank top water-fillers as there is no commercial casting available. I'll make a Silicone Rubber mould from the pattern and cast them in white metal though the upright closing handle will have to be made from brass due to its vulnerability.
