David Andrews Princess Royal – More Pipe Fittings

The Princess continues to challenge.

The replacement for the live steam injector pipe took much tweaking and test fitting before it fit snugly with the chassis in place.

Once I got my head around how the pipes ran, the two front oilers didn’t present too much of an issue although I had to look at a good number of photos before I worked out where said pipes ran.

Next I removed the pin rom the bottom of the steam pipe castings and drilled and tapped them 10 BA so that I could screw them to the footplate through the mounting holes

As can be seen from the snips below there is quite a gap between the boiler and the steampipe flange. At the moment I am not sure where the problem lies, whether it’s in the placement of the mounting holes, in the dimensions of the castings or something else. Initially I tried turning down some washers to fill the gap but I don’t think that’s the answer.
