The rudder bracket was made and clamped in place to test the movement of the rudder. The rudder moved side to side with ease .The brackets were brazed on to a mounting plate to make hanging the rudder easier. The servo for the rudder will be next.

The rudder bracket installed worked on servo position and building linkage from the rudder to servo. Test of servo rudder went well. Two mini servos set up one for forward and reverse the second for steam shut-off. Pictures show covers for electronics and servos.

Hi Martin With the limited space for the servo and arm I built the pivot arm with threaded rod to be able to connect the rudder through the transom. Looks a bit off as the arm was built from my parts box a one of if you will.

With the servos set up and tested worked on the engine and condenser placement and installation. Built a base for the condenser and epoxied in place. The frame were trimmed down to let the engine base sit at the right level and angle to the prop shaft. Next the frames were trimmed for the boiler to sit lower in the boat. Boiler was lagged in place. All three engine condenser and boiler are set up for easy take out to clean and repair if needed. Rick

Magnificent magic Rick 😮
Can't wait to see her in action with steam up, showing us the REAL meaning of Full Steam Ahead! 😀
As a dumb electronics eng. who only knows 'fuel' as electrons 😁 I take my hat off (if I still had one😂) to all you oil soaked steamers 👍
Cheers, Doug 😎
Servo linkages were installed from engine to servo and shutoff to servo all set up and tested. Paint and water tests yet to come.

I very much hope you take this as constructive, but one thing that concerns me is the proximity of your servos and receiver to things that radiate quite a bit of heat.
Stephen pointed me to a heat problem with the servos close to the boiler. Found a small piece of aluminum cut a pattern to fit into the servo base to shield the servos from the boiler heat.

Hmm! I wonder if a metal 'shield' will help or actually make things worse?
I fear that the metal will heat up and conduct the heat directly to the servos 🤔
Might you not be better off with a a wooden shield (1/4" ply?) which won't absorb and conduct heat so well? Just a thunk Rick😉
Cheers, Doug 😎
I hate to appear picky but unfortunately Aluminium is quite a good conductor of heat.
If there is an air gap between the Aluminium and servos this would be ok ( air doesn't conduct heat well ) or a piece of something that insulates ( wood is not bad at insulating and Balsa is a really good thermal insulator )with a piece of reflective tape applied to it to reflect an amount of the radiant heat back to it's source.
Over here down under heat reflective tape is available at hardware shops either in the plumbing or building section, online or auto shops a roll doesn't cost a lot and will last you a long time.
You could stick some of the tape onto a piece of Balsa with the tape facing the boiler and it might work fairly well.
I will try not to be critical next time.
With Stephen and Doug's advice made a wood cover to protect the servos from heat. Pointed out to me that my aluminum bracket although a good idea was a good conductor of heat suggested a wood cover .Job done.

The best way to insulate a servo from a heat source, is to use High-Temperature 1200*C Ceramic Matting 2mm or 3mm thickness, then wrap that with chrome tape to prevent damage. also ideal for insulating a boiler before fitting the wooden lagging strips. Available from: Polly Model Engineering, or Kennions Model Engineering. Better and more efficient than anything else I can think of and they will both cut it to the size you require, easily cut with scissors and similar to thick felt-like material. I would go for the 3mm thickness around about 1/8" Regards. Gary.
Yesterday turned into a good day able to get a primer coat on the boat. A number of areas need a bit of fill and sand. All in all pleased with the result.

Hi Rick, pleased to hear you are making some progress with your latest project, although I am not sure quite what it is? So with that fact in mind why not share it with a friend and post some photographs. Regards.
