OK' so lets play spot the missing rivet

Had a request from the yard for a supply of the smaller cross bollards for the mooring ropes . Thought it would be easier to make them out of boxwood rather than brass like the original bigger one. Prototype seems OK , just need 5 more

Onwards and Upwards.

The cross bitts can be had from Cornwall Model Boats, made in plastic and in various sizes, cheap as well.

OK for cross bits but if anyone knows a retailer who does a fire monitor of the type fitted to Cervia I would like to know, otherwise it's back to scratch building .

OK scratch building it was, not exactly correct in every respect but acceptable if you do not look too hard. And yes I need to buy a tin of red paint next time I am near a model shop.

Hang on where the heck has the green attachment icon gone ?

have i found a workaround

Need to rub a bit of the red paint off the snozzle

Make a start on the towing hooks , thought for quite a while what to make these of , ended up with styrene and brass.

Very nice Baldrick 👍👍👍

Thanks tugmad.
coming back cold and looking at the photo I suppose the fill covers on the oil tanks would have had a turnbuckle or latch to hold ihem tight

that tow hook in styrene looks the dogs doo dahs.

I don't know why, when scratch building, people shy away from the stuff...….a great medium open to many uses.

Thanks Neil.
Have to agree that Styrene is nice stuff to work with . Previously always been a wood guy but since using styrene find it so clean and precise that it allows you to incorporate greater detail. You can bend it , cut it , etch it for doorways etc glue it taking care not to get the solvent fumes too much. Paint takes to it like a dream. you can carve it and imitate wood by rough sanding and woodstain. Only thing it won't do is go through the mini bench saw.

Stonking great big chufferoony. I thought first of all that I had got my dimensions wrong, particularly as she is ( was ) an oil burner but that is the correct size . It appears that she was built so that at anytime she could be converted to coal burning which doubtless accounts for the size of the stack.

Hi Baldrick, that odd shaped plate on top of the funnel is only a cover plate ,put on to stop rain getting down there .put on by thr chaps that are restoring her.

JimG · « **Reply #67 on:** **Yesterday** at 07:30:31 PM »

Havn't you got it backwards? Funnels normally tilt to the rear not the front.

Hi tugmad.

Confess to having got into a dilemma here. The drawings (can't bring name of draughtsman to mind

) show a profile plate or shroud to the top of the stack. It shows on the plan projecting forwards of the front edge of the stack , the inner line is the line of the inside of the flue when projected upwards. This however does not show up on the elevation. What I took to be this on photo's must be the cover plate you mention . If it is not correct I will zip it off before painting . cheers

A couple of pictures of Cervia,s funnel one with Watkins colours which were from the bottom 1/2 funnel height black with the top half split 50/50 red and black.
The other in ship towage colours with the added blue band and thecElliot flag attached in the red section.
The separating bands around the funnel were only 3” half round bar with no vertical strips on the outside at all,
The funnel size on the drawing is the complete outer shape shown as the funnel top it is quite a large oval.

derekwarner_decoy · « **Reply #71 on:** **Yesterday** at 10:31:50 PM »

Baldrick.....I have a slightly different take on your Plan set

The oval shape superimposed AFT of the engine roof level oval simply represents the shear or angle of the chimney toward the AFT end of the vessel. The blackened area is simply the only overlapping profile between the two and is of no consequence in any build

The yellow lined oval is the actual inter funnel casing, the green lined oval is the outer shell casing of the funnel. The is an air space between the two was also used for modest heat exchangers or water heaters

If weight was not an issue, an internal oval formed pasti-card representation [sprayed flat black on both sides] would be scale like

You mention that Cervia was oil fired, but was capable of a relatively simple modification to be coal fired. So the designers included a coal fired chimney

Naturally a hand fed coal fired boiler required a larger volume of air draw & hence the larger surfaced area [and taller] chimneys over a pressurized oil fired boilers etc

Hello, I've only just stumbled across this thread, looks like a very interesting build - I'll have to have a good read through
