Conversion under way. The headstock to buffer face is around 29 mm, so just under two feet for both 16mm and 15 mm to the foot. I have decided to remove the black from the face of the buffer on Kestrel (shown below). Looking at photos of full-size choppers, mostly they show a steel colour. The buffer head is too big as well, so I suspect Mr Dremel will be in use shortly to reduce the diameter, at least on the front buffer. I am not sure if this will affect the working but Kestrel rarely runs bunker first anyway. The EMR has a very efficient loco-turning mechanism ;). Views on this and other coupling matters very welcome.

The four bolts which come with a pack of two Accucraft couplers have a head which the Accucraft user will imagine are M2. Not so. I don't know what the thread size is but the heads certainly do not fit into a 3.0mm nut runner. Not even nearly. They do, however, fit into a 3.2 mm nut runner. Just thought I would mention it
