  1. Looks nice Dave.  Regarding Lentz or Reidinger valve gear.  If the cardan shaft universal joints have shrouds then it is Lentz.  If joints are exposed then it is Reidinger.  All the Crabs fitted with rotary valve gear (42818, 42822, 42824, 42825 and 42829) were converted to Reidinger in 1953.  I still haven't finished my model of 42825. It stalled as I wanted to make better looking UJs for the Reidinger valve gear.  The Comet UJ castings are very overscale.

  2. Perhaps John but I didn't really think so. It is something that you would walk / stand on. Maybe I should have said "foot plate" rather than "footplate".  I hope Ivan isn't still scratching his head with a dismantled 9F in front of him.

     

    Anyway, it is all academic now as Dave has guessed correctly. It is a master for one of the Barrow Road turntable kerb castings.  There are 24 of these that, as Dave rightly points out, go in the 4 foot.  There are two further kerb masters to make. One goes in 20 locations in the narrow gap between roundhouse roads and the other, the largest of the three, goes between the roads that have a roof support column.

     

    I'll draft a new blog posting when I get more time to explain how I made them and how I intend to make the replicas.

  3. Hi Andrew,

    This seems to be progressing very well. With respect to your crank throw problem would a bit of work with an escapement file at each inside end of the slidebar solve the problem? By the looks of it only an extra 0.5mm or so would be needed at both ends. You might also be able to cheat a bit off the front and back of the crosshead with a file.

    Cheers....Morgan
