Hi All
The photo below shows a cradle I original made to machine the various holes needed on the boiler and to machine the side horn plate mounting bushes. But this has also doubled up as an aid to spray paint the boiler. It normally has two clamp rings but as the boiler is masked off these were not needed to clamp the boiler for painting. I know there are a few model makers among the HMT community and hope this will be of interest to you and also those that are not model makers.

This is the link to the wheel spraying jig I have made for the same model.
