Screwing in the stud bolts for the steam chest, ( valve box ).

Originally I was going to run the engine and prop from a double shafted motor, but I got to thinking that might be too fast for the steam engine so I decided to run it from its own motor at a lower speed, I have plenty of universal couplings but because of the space available I made a simple drive coupling from some scrap brass etc that I had handy, turned a piece of brass for the steam engine part of the coupling.
Shows the part attached after drilling and tapping it for the grub screw and also one of the arms in place, you can also see one of the two oil cups in place on top of the bearings.



231.jpg
View of the finished coupling, the arms still have to be cut down to size.





233.jpg
This is the other part of the coupling that attaches to the electric motor, it has been turned to size
and drilled for the arms and the grub screw.




234.jpg
Shows how the coupling will work when finally located in place, the electric motor will be hidden
inside the dummy boiler.







235.jpg
Close up view, when working it will be more evenly aligned. and the arms trimmed to size.

I decided it would be better to have the electric motor under the floor so I have cut away part of
the deck in readiness for it.


238.jpg
Next up were the bollards, I made pads for these to sit on, pic shows two bollards with pads
attached and a pad on its own.

Bollards and pads after painting.


240.jpg
I drilled a 0.7mm hole in each corner of the bollards and used small cut down pins and super glue
to fix in place, one pin to hammer down.

Thank you for looking,

Stag horn cleats for hanging the lifebelts on, two of the life belts hang on these and the third lies
flat on the aft hatch cover, also the supplied ships wheel after a coat of varnish.

that colour and requested the blue version,

Have started work on the dummy boiler.




252.jpg
I used part of a 90mm plastic storm water pipe for the boiler shell, and a solid brass bowl for the top of the boiler, this shows the bowl upside down, I removed the base later on.




253.jpg
Shows the bowl right way up.


254.jpg
I found the centre of the bowl and drilled a pilot hole, I then enlarged the pilot hole
by cutting it out on my scroll saw.


256.jpg
I then scribed the bowl to the diameter that I took from the outside diameter of the storm pipe,
and cut it to size on the scroll saw, then I desoldered the base and polished up the cut out piece.


257.jpg
The boiler shell cut to size with the top sitting in place, not attached yet, you can see the
reason I used the brass bowl, it has a nice round up to it. The boiler has to be clad with
wood and also have the furnace door and all the other pipes etc added.


258.jpg
Next up was the funnel, and I had decided to use something a little different from the plain funnel I had,
I had previously had a look through my scrap box and come
across this brass flower vase, which with the nicely flared top looked just the job.
So I used this and a piece of Copper tube also out of the scrap box.


259.jpg
Parting off the top piece that I wanted.

Just cleaning up the cut.

Temporarily in place, just to see what it looks like.

any questions or comments welcome,



best regards John.

G'day Guys, thanks for all the nice comments and the likes, I have now started working on the dummy boiler,


265.jpg
I turned up the fixings for attaching the steam pipes from the boiler to the engine,
and also the steam pressure gauge.

266.jpg
Just to show how the pressure gauge will be mounted.

Starting to clad the dummy boiler.

270.jpg
This is where the North west Chopper really came in handy.

271.jpg
One plank to go.

272.jpg
finished, it still needs a good rub down, and also the brass holding bands.

With the boiler top and funnel temporarily in place.


274.jpg
First coat of varnish, will need a little bit of filling before the next coats.



276.jpg
I have not done a lot today, just varnished the boilers wood cladding, cut out the wood supports for the inside of the boiler and soldered the funnel top to the funnel and then the funnel to the boiler top.


277.jpg





278.jpg
Temporarily attached together, the next thing will be to cut out the fire box door and drill holes for the boiler pipe work, thanks for looking in,


best regards John.

I have had to make a few changes, with the motor going under the deck I found that I had to lift the deck area were the boiler and steam engine were going so as not to foul the electric motor and also the smoke generator. This is the top of the raised area, that the boiler and engine will sit on.


280.jpg
Where they will sit

281.jpg
I had to cut more of the deck away to allow for the smoke generator and the electric drive motor.





282.jpg

The raised deck area, I drilled and inserted four brass pins into the upper deck area around the edges, these pins then fit into corresponding holes in the lower deck.
283.jpg
I have decided not to have the electric motor that will drive the engine in the boiler, as the tube for
the smoke generator would be in the way, this pic shows the new location for the motor, but I will
have to cut some of the divider away to allow the motor to connect to the engine flywheel drive.

284.jpg
This is the carcass that will now house the motor I am hoping it will look like a gearbox housing for the drive gears for the prop shaft., the cut out areas will have mess inserted to provide air flow for cooling the electric motor.

285.jpg
This is what I used for the mesh, it is just a desk top pencil holder from the $2 shop,
or perhaps I should say was.

286.jpg
The carcass after the initial planking showing the mesh in place, this will be glued in after the varnish work.

289.jpg
After the paneling has been attached.

These next five pics show the boiler after the furnace doors
have been cut and glued in place, I will hopefully have a
flickering red light inside so as to look like a fire is burning.

drilled and fitted the connector that will hold the Steam Gauge, and also fitted the water Gauge.

Closeup of the steam gauge. Note the bandaged finger, I had a run in with my table saw, the saw won and claimed a slice off the top of my finger,

best regards John.

Steam supply pipe connected to the engine.

301.jpg
I needed a glass rod to go in between the fittings for the water gauge, so this is what I used,
it is the cellophane tube that lengths of brass are sold in, I had several and they were just the right size,
just have to work out how to imitate water in it, I will probably try epoxy glue.

First attempts at the steam whistle, but not so good.

Well I needed some wood for the boiler, I had some small branches that I had picked up months ago
so I thought I would cut them up into logs to look like the wood for the furnace on the launch.


305.jpg
Branches as picked up.

306.jpg
Cut into miniature logs.

307.jpg
Will be stacked in the hull something like this,

thanks for looking,
best regards John.
