Having run the steam plant a number of times on the bench, it was time to install the steam plant in the hull and run it there as part of the final preparations for the maiden voyage. The steam plant fits on two locating pins. As the plant goes into the hull, the splines on the drive shafts from the engine are slid into the ends of the prop shaft. The only connection needed is for the rudder servo to the receiver. Everything else stays connected and is removable from the boat for servicing. The steam plant ran well in the hull with the superstructure on, here is a link to a video of it running without the superstructure. It's running here at 20psi but also runs very nicely at 40psi with the attenuator maintaining the pressure with the engines running.

The next step wass to confirm what is actually required by the Boiler Test Code for under 3 Bar Litres (Orange Book) for this boiler in terms of testing and recording, so that the model can be used on the different lakes that I visit.

Re the message flags, they bring some added visual interest and John did a nice job of printing and installing them, and we have been ask if the flags mean anything? Well yes they do, its actually a personal message from us that says "Thank You NHS John Dave" its not just a COVID message, we both have a lot to be thank the NHS for, so it felt right.

Now THAT is what I call "on a personal note"...

Well done!

Blimey Dave that’s a lot of bits 

I did count them once on the 3rd one I built as I was sanding all the flashing and joint marks and got 1416 white metal and other fittings!.....boy were my fingers sore for days lol.

Neil Building three is a big commitment and a great achievement well done, you are right about the fettling of the fittings, a necessary evil, but the end result is worth the sore fingers

Building Perseverence has been a learning experience for which both John and I learned new skills, one such skill for John was learning about LED lighting. We discussed lighting and wanted the engine bay illuminated so it was easy to see to carry out oiling and checks. We needed navigation lights and also wanted some lights in the cabins. John cleverly hid the wires for the navigation and mast lights running the wires in grooves in the mast and installed the cabin lighting in ducting so it could be replaced easily in the event of a bulb failure, initially supplied with power from a stand alone four cell power pack, later an rc controlled switch will be added. The lighting works and is effective although it has been suggested it's too white and a softer yellow/white would be more realistic. Anyway the point was to learn and we have achieved working LED lights even if a few LED's were popped in the process!

Bonjour David,
Great job indeed  This boat deserves now a night navigation !

[DBS88]

Whilst not quite a night time navigation, here is Perseverance lit up,  at the lake as dusk falls

Very nice work, Dave. Congratulations!
