Yes indeed

The drain cock sourced from German eBay is fitted.

The cast metal base has been in my new sandblaster and given an etch primer coat.

So two coats of etch primer, and three coats of enamel paint and the base is done.

The same treatment to the flywheel. An unusual type made from a cast lead alloy, with a brass hub and brass outer casing.

Two enamel paint jobs on the flywheel. The reverse face matches the base whilst the outer face is red. The drive shaft polished up bright on the myford and reunited with the flywheel.

As the previous post will show. The boiler has been mounted back on it's base and secured with 5Ba cheese head slotted screws.
The steampipe is a complex affair as it loops out from the steam valve, drops vertically and enters into the firebox via a vent hole and to the steam inlet on the rear of the slide valve engine.
A slide over spring coil pipe bender earns it's money on this.
