Thanks for your kind comments Pete, I must say that I am actually very pleased with this myself even the good lady was impressed.
Here are the drawing for the lubricator and bracket bottom right in the plan photo, take note these are from a very old edition book (see photo) the bracket fixes to the frame using the two bolts that secure the drag beam to the frames.
Sorry about the pic quality, poor lighting in the workshop. Hope this is of use. The rear pipe work is easy its the front ones that caused me problems in getting it right and it looking right.
Haven't got to try the new regulator yet so no news on that tonight, might squeeze sometime in the shop tomorrow.
I meant to say earlier that I think the holes in the sides of the Belpaire firebox are a neat finishing touch. I have seen a few photos of the full-size and some of these have them - definitely a little different from the majority of Projects I think.
Not sure what they are for but they appear on two photos I have, might be for air circulation . But they do make a difference, I put them in after bending the Belpaire to shape it just looked right. Forming the Belpaire was time consuming as you need to make it to fit your splasher and this meant a lot of trial fits, well I had to anyway.
