Ahead of the Wigan Show in December we applied steel loads to one of our rakes of bogie bolsters. Nothing too complicated, simply lengths of Evergreen H section plastic cut to fit, sprayed initially with Halfords acrylic grey primer and then treated with the usual palette of Humbrol matt black, leather and white via an Iwata airbrush to capture that very slight weathering that new steel quickly sports when it is open to the elements. No further finishing required other than a spot of glue to secure them to the wagon cross beams. Plastic strip such as this can be fairly greasy so give it a rub down with a brush and soapy water before applying the primer. This will avoid a bubbly finish! And don't forget to trim and file down the girder ends if you have used hand cutters or a file to cut the lengths.
The end result was a business like rake of 8 bolsters for our down line freight services. A quick project but very effective.
