Thank you so much for the lovely comment,

Continuing with the lanthorns the three of them have scrolls each side of the connecting rod, I have not seen these on other Period ships, the only thing I can think is that they are a platform for the sailors to stand on when lighting or maintaining the lanthorns.


First attempts,



I should have soldered these on before attaching the actual lanthorns themselves, but now I jusst CA glued them in place and bound them with some very fine copper wire,



close up view, still have to tidy up the binding copper wire,


My supply of copper wire,



view from above,



and from under,



and on the Period model,


best regards John.

Its been awhile since I last posted so this is a bit of a catch up,


I drilled and fixed eye bolts to the lanthorns and also the transom, this pic shows the measuring for the attaching wires,



After attaching the wires,



and several views of the attached lanthorns,








thanks for looking in,
best regards John,

the molds for the anchors dusted with talcum powder,



and the anchors after casting, they need a bit of a clean up,



after a bit of filing and also with the rings attached,

best regards John.

Whilst I was casting the anchors I decided to also cast the Dolphins for the stand at the same time, this is the open mold for the Dolphins,



And after casting, I have already removed the clamps from the mold,



and the open mold with the cast Dolphin,



Still have to cut off the sprue and clean them up a bit,



This is how it will sit, only it will be on the cradle that supports the ship,



and the four Dolphins in front of one part of the cradle,

best regards John.

That mold work is very impressive John, particularly those dolphins.

 

[Kurt Konrath]

Making molds is not hard if you have a wax master to use, old jewelry process called lost wax casting.

Fun part is coming up with the design to make the wax originals for use. If you had a plastic original you could use it to make a mold for making the wax casting.

Very nice work.

very impressive work!!

Hi John,
Lovely work, I do like the casting.

Cheers,

That would make a terrific thread on "how to" in the Tricks of the Trade" subject here at SoS. LOVE the dolphins!

 

[DARIVS ARCHITECTVS]

The dolphins are awesome!

Thanks guys for the comments and the likes,

After making and shaping the stocks,


Holes drilled out for the shaft to go through, then I squared the holes with a small file,



checking for fit, they need to be pretty tight,



and after adding the reinforcing bands,



all four done,


best regards John.

G'day Kurt, have you done any lost wax castings, I checked up on it and decided to go with the RTV Silicone rubber, from what I could find it appears that with the Lost Wax Casting method you have to make a master out of wax for every part that you want to cast and then encase it in some sand or plaster and then when you pour your hot metal into the mold it melts the wax and the metal sets in place of it, and then you have to break open the sand or plaster mold to get the part out, so if you want to cast 50 cannon then you have to make 50 wax cannon etc, whereas with the RTV Silicone you only have to make one master to make the mold from and then you can keep on using the same mold over and over again, is this right or have I got it all wrong, just wondering,

best regards John.

I think your right on the method, I have done one or two items via wax casting, and it was "one off" example of how to make jewerly rings. Not the best for repeated operations.

 

[Roger Pellett]

Maybe I’m out of date, but my understanding is that the mold is first cured by baking it in an oven. This also melts the wax master. The hot metal is then poured into the EMPTY mold.

Hot metal and moisture is a very dangerous combination resulting in the metal being violently ejected from the mold. Pouring hot metal onto wax might also cause a similar reaction.

[dockattner]

Roger has it right. The pattern has to be melted out before molten metal can be poured (or cast if introduced via centrifugal force).
