Sleeper constructed railway buffers for coal yard

A laser cut OO scale model of a sleeper built buffer stop to hold coal. For use in the small coal yard on my layout.
It was cut from 3mm birch ply. The files include a supprt to glue inside the sides (cut two) these will hold the 'table' to glue the coal onto.

The blue layer in the dxf files was etched at 100mm/s and 20% on the 50W laser. This gives a separation between the timbers and I added some old bolt holes. Post gluing I have started a little distressing for the edges and joins before
