Hi Steve
Thanks for the comment and the question.
With regards to the solebars:-

Do they have separate overlays?
If so what thickness do you use for the overlays?
Is the river detail etched or punched from behind?
If punched from behind may I ask what tool do you use to get such consistency?


Here is a picture of the underframe etch. It shows that the solebar is a fold up with a half etched insert so that the rivets are uniform in height and width.

It's etched in 12 thou nickel silver so that the half etch is 6 thou.
The solebar steps when folded up need the rivets pushing through from the back, I use a GW Models riveter but have since made new tools to fit it with different points and angles to the 45 degree pin point supplied and use the Limiter to keep the same depth.
I must admit that depending where the rivets are I sometimes just push them out with a scriber.

Looking forward to the point when one can order this just like the Iron Mink.

Any thoughts on likely pricing yet for the underframe kit complete with castings etc for the powered bogie?

Sorry Not as yet. Not finished the Castings still need to make the Bogie axlebox and springs.

Although things are getting closer, I have been re looking at the mounting bars and trying to get more rotation. This I have done by drawing up an etch which folds up into the two bars connected together with a central pivot then that can be screwed to a plate on the chassis giving the impression of fitted to the chassis mounts.
First test etch showing 3 units OO EM and S4 spacing.

Plate fitted to the underneath of the chassis by the four screws as if mounted to the beams. A shouldered 8ba nut soldered through the central hole. The beam unit also slots over the nut so that the screw can be done up tight while still giving free rotation.

Chassis fitted to the underframe the screw can be just seen between the beams.

Hello Jeremy.

I may already have asked you this, but in case I haven't, would you put me down for one of these please when it is available?

It looks very good.

Thanks - John

Exquisite work, Sir!

Bang me down for a pair. (for the future, when I can solder at the subatomic level!)

Regards,
Bernie
