After a longer gap than  would have liked attention had returned to my Duchess build.Starting with the lower firebox and damper operating rod.

Next up the brakes. As can be seen clearance is kind of on the minimal side.  Theres no springs fitted yet either so the chassis will sit a little higher than is seen here.

The motion brackets. Again theres not a lot of clearance between the bracket and the leading driving wheel.

The chassis so far.

Moving on the next stage is the footplate Seen here in its assembly jig.
