Once the springs and hangers were added to my class 08’s I started looking at other things that could be improved in the frames area. 
The obvious thing missing from the Bachmann model is the speedo drive but its dead easy to add from a few bits of evergreen strip. There are also some holes in the frames that Bachmann missed so these were drilled using photos as a guide.
On the other side the missing holes were added as well as a drain cock – this was simply made from a brass pin with the head filed down, a bit of fine tube and a bit of brass rod. Fiddly but a nice quick improvement project.
A well timed post this Jim. I’ve got the springs to add but some other bits have turned up too… but I need to fabricate the etches first … hopefully they’ll improve the 4 corners a little … I’ll share more once I’ve convinced myself I can put them together 😉 Currently having a break from all this and doing some pencil work instead – I’ve been neglecting my deltic drawing of late! All looks good and I’ll be back.
best wishes…. Jon
