Leverage

At first glance this doesn't appear like a significant update, but look closely and you'll see there is a brake lever appeared on the bogie of the MOD flat.

This is quite a nifty bit of casting, if I say so myself.

It started out as a master piece which was taken from an offcut of an old brass fret in my rubbish pile (I'm dreadful for never throwing anything out) and then carefully shaped with a file to include the 90 degree bend at the end.

This was then used to cast a prototype piece and recast twice to make a production master, with the addition of a small piece of styrene at each end to represent the pivot bolt and to beef up the small handle and make it more reliable to cast.

In an ideal world this would be best done as an etched brass fret, but 2020 is very far from an ideal world and I think there would a very long lead time on procuring a part like that, so hopefully a resin casting will satisfy most modellers.

If not there's nothing to stop you scratch building your own levers.
