Narrow gauge locos don't often have buffers outside of Talylln land. Mostly there is some sort of chunky centre coupling. The Barclay kit comes with some brass fold-up buffers and these look suitably industrial, so I decided to use them.
Except that in real life I suspect they would be made of wood rather than solid metal.
Not a problem, in the material stash there is some strips of hardwood. I removed the buffer sides and stuck the faces to the wood. Once dry, this was sawn and sanded to match.
For extra industrial appearance, I added bolt heads using fine brass pins. These are fitted into holes drilled in the face and wooden bloc but not through the buffer beam. Doing what I did cost me 3 drill bits which is plenty thank you.
To be honest, I'm not sure about the bolts. Surely they would stop the buffer faces sliding? However, I found real locos fitted with them and the metal faces would have to be held in place some how. It's not likely that they'd have used a big pot of epoxy glue!
