On my standard gauge I have used B & B for years. The key to consistent
operation was the replacement of the etched dropper by some soft iron
(florist?) wire. Thus I was interested to see Steve's comment < With
the DG, there is no need to make up the loops as per the instructions,
it is far easier to bend up the loop and dropper as one complete unit,
soft steel wire and a lot easier then to make small adjustments.> This
will also help the action of the magnet. BTW what sort of magnet is
needed and how is it mounted? Used home made electromagnets with the
Peter Whitehead mentioned that he had added a photo(s) to the Photo
section of DG coupling but I can't locate it/them. Slow speed
connection is frustrating and I finally gave up the archival search

- Yes, the buffing plate is 8mm across, the body of the coupling though, is only 4.5mm. Once installed and painted, they are pretty difficult to see, between 2 wagons coupled together, they are almost invisible.
Put them next to a Kadee No5 and it really brings home how small they are.

I see on http://www.modelsignals.com that both 4mm and 7mm couplings
are 8mm wide. Even in On30 that seems a fairly wide coupling - it's
almost half the gauge (indeed, wider than half the prototype's gauge
of 2'). I think I might have to modify my drawings so they have a DG
attached so I can try and visualize their appearance.

>The only difference between the 4mm and 7mm scale versions, is the thickness of the brass they are etched from. I would recommend the 7mm as they are more robust.
>There is no need to form an actual curve on the buffing plate, just a slight bend back on the sides is all that is needed. You would need extremely tight curves to need anything more than that, the loop would come uncoupled long before you got that tight.
