David Andrews Princess Royal – test fitting the boiler and smokebox

New
Since my last post I haven’t had much time to spend on modelling but having tacked the cab on I did get to drilling and fitting the firebox to the foot plat with self tappers so that I have a datum to work from for seating the boiler.

I am not sure how others have managed it but I am having real difficulty with the size of it seeing what’s level and what isn’t so I have resorted to nibble a little bit, fasten the foot plate to the chassis add the boiler/smoke box and then take a photo that I can study without trying to juggle to loco in my hands while squinting at it.

By taking a photo of each side and comparing them, I can immediately see that I need to take a little more off the left side middle splasher. This is because it’s not seating down flush with the front of the firebox at that side, but it is at the other. This means that it’s being pushed over to one side slightly, this is backed up by it appearing to seat on the secondary saddle at the right side but not at the left. And of course, looking at it from the front.

Useful things photos, and it is a slight pain assembling it and disassembling to take a bit more off but I can’t think of a better way of achieving what I need.
