David Andrews Princess Royal – Boiler Fitting

This weekend has been about working out how to fix the firebox and boiler together and to the footplate. I put a couple of 12ba screws through the bottom of the firebox utilising the two holes etched in the footplate. The ultimate intention is to use adhesive but also to use the hole to dd a mechanical element to the fixing so the screws are temporary to allow me to get everything in place. I would also like to get all the soldering done around where the firebox and the lower sections will sit since resin is susceptible to heat damage if I am not careful. Picking up a tip from John Dale I elected to screw the front end of the boiler in place and I was rather reluctant to use just a nut on an internal curve as I didn’t want it to come adrift sometime in the future. A rummage in my useful bits of brass recycling box yielded a former frame spacer from a set of frames that I had replaced with new ones. As a bonus it was already tapped 8BA. I filed the ends to help it seat in the curve and after marking and drilling a hole in the front saddle casting and transferring that through to the bottom of the smokebox I soldered it in.

A dry fit of the boiler and firebox and all of a sudden it starts to look like a loco.
