West Country Conversion to P4 part 2

Not much progress in the last couple of weeks due to work commitments, but I have managed to complete the bogie and get the wheels quartered.

 

The wheels trial fitted in the chassis block. I used a mixture top hat bearings and ordinary 1/8" washers to suit. The wheels were quartered using my NWSL quartering jig, which I find easier for RTR conversions than the GW Models one. I'm wondering whether to fit cosmetic sides from plasticard. I might make some up with slots than can be put in later on.

I'm also having a think about the keeper plates and am inclined to squeeze the brake gear out rather than cut and shut.

The original bogie is cut down the middle and a new stretcher was made from 15 thou nickel silver. The whole thing was epoxied together. I didn't bother with the cut out as per the EMGS manual as the material's so small I don't think it will be noticeable. The swing link pin was fitted using a 2mm top hat bearing for the sleeve and fixed with a 10BA nut & screw.

Lastly, the cylinders have had some plasticard added to fill the void. I'm planning on shaving off the 3/4 cylinder head cover and fitting a new one. Thinking about fitting a bush to take the piston rod

Looks good.

With regard to my comments on your last entry. The first picture really shows how far inboard the bearings are.

 

On my conversion I filled in the gap between the bogie halves with some liquid lead held in with araldite. It adds sufficent weight to keep it on the rails. The original (that featured in the photos on the worksheet) is as yours and does derail at slightest fault on the trackwork.

 

I shall follow progress with interest.

There are a couple of West Countries on St Merryn that have been converted in much the same way. Jeremy Good did them so if you want me to ask any questions I can do so.

Hmm, I wonder if it's possible to incorporate some form of load bearing springs to act on the top of the bogie? Wouldn't need much and a simple wiper could act on the top of the nickel silver. I did wonder whether the top of the screw could be used in some way shape or form in this purpose...

The interesting thing is that the chassis block appears close to the real thing's spacer width of 3'2". You could put some plasticard overlays (5 thou?) to simulate the frame detail / hornblock guides.

 

I can't remember whether the bogie width is the same or wider.

Porthchullin Tatty is right that there are a couple of converted West Countries on St Merryn but despite his suggestion I didn't do the conversions. I have one in my started but not finished box which involved using Comet frames as cosmetic overlays to try and deal with the brake gear problem mentioned but I can't comment on how successful that will be as I've not finished! The St Merryn WC's, from memory, follow a similar route to ullypug's.

Just looked it up: the bogie width was wider, so you were correct to widen yours.

That's reassuring! I've got the Irwell Press book on the WC/BB's and it looked wide in there though I confess I didn't actually see a dimension anywhere.

The bogie stretcher came out as being 4' 1" wide (unless I've misread the information), in effect conventional spacer width, so you've got nothing to worry about there.
