Hi,
Decided to fit the boiler into the hull by using the same system as Bowman did bolts through the bottom of the hull.
The steam dome was then made and fitted which allowed the boiler to be tested. A poker burner was used for this test which just had about enough power but a large ceramic burner will be made and tried.
A very short video as the camera ran out of memory. I will make a longer one on the next test after a suitable burner and safety valve have been made.
Regards Tony.

Hi,
We have just enjoyed a two weeks holiday meeting friends and playing trains on the flat lands of the Netherlands but it is nice to get backto the hills and mountains of Wales.
Polly Wog was taken away with us in the traileralong with the railway layout, the intention being to give her her first sailwhile in the Netherlands. Alas thoughthere was certainly enough water and the weather was fine the high windsprecluded any chance any of Polly Wog taking to the water. We left the Netherlands and spent the lastfew days away travelling through Belgium to the ferry that would take us homefrom France. So it was getting to lookif Polly Wog wasnt going to get her first sailing in mainland Europe just a1000-mile trip in a trailer! We arrivedwith our camper van along with its trailer and camped on the dockside in Calaisready for an early morning crossing to Dover in the next day.
While playing trains in the Netherlands our friendsElinor and Nick who after a holiday of some weeks in the Hartz Mountains ofGermany came to help run our railway on their way home joined us. They were with us camping on the docksidebefore returning home to the UK via the tunnel. While walking on the front in Calais Nick and I passed a childrensamusement park at the top of the beach. The park looked closed for the winter but a large portable pool wasstill full of water!
So Polly Wog was removed from the trailer R/Cbatteries fitted, her engine oiler up, fuel tray filled with Sterno and withwater in her boiler she was taken to the pool. The pool was ideal its high sides protecting the water from very highwinds. First a bit of a problem the gas lighterwas empty! So a Tabac to gets some formof ignition had to be found.
Having fired up the Sterno dispite cold high windsPolly Wog was soon making steam and was placed in the water.
How did she perform? Well she is quite fast giving her shape and weight. Alas the R/C rudder has very littlecontrol. The first very short videoshows her first run in open water. Thelarge propeller torque and a flat bottom turned her with the rudder in linewith the hull, so some time was spent off setting the rudder to compensate forthis. With the rudder off set shetravelled in a straight line but with still not a lot of control. The second short video shows the tuningprocess, retrospectively it might be better to off set the propeller ratherthan the rudder to compensate for the torque of the propeller. The third video shows Nick in control? By now the Sterno is getting low and speedmuch reduced. It was getting cold andtwilight was setting in and a meal and drink was needed so Polly Wog will haveto wait for a larger rudder to be fitted before her next try in water. All in all Im quite happy with Polly Wogs performance possibly not as fast as the 6mph claimed but fast enough.
