Working copper bilge-pump 1820, 1:64 scale


Recommended Posts

The "working" copper bilge-pump with two valves and removable head in 1:64 scale

 

Important note:

There is no guarantee for historical conformity

 

The pump's sketch was designed based on reseach:

 

«Ships' bilge pumps: a history of their development, 1500-1900» Thomas J. Oertling

Materials:

 

The real implementation forces to change pump proportions for a little: follow up to standard set of copper (and brass) tubes: 3/16'', 5/32'', 1/8'', 3/32'' and 1/16''.

The chosen tube set is giving a great opportunity - the inner diameter of a tube corresponds to the outside diameter of the tube оf next number – the tube move -in and -out into each other as closely as possible.

 

Designed etched details on brass 0.6mm thick were good for nothing – I had no inexperience, and did not add 20% of the thickness to the edges of small parts, so they were eaten to be useless ... Nevertheless head cover and the base bed are ok. But the remaining parts – handle, support and stock - should be done by hands.

 

And yes!!!: a metal wire from the package of bread and brass washer with 1.5 mm inner diameter.

 

Also I have to say: an idea to make the pump “working” came while of assembling: that was happen that I have steel balls with 3/32’’ and 1/16’’ diameters (I bought them to simulate charges for 24’ carronades and 6' guns, respectively)

 

Oops!! One more thing: a 00-90 bolt

And where a photo from the last messages?

 

Wait for it Garward - mir0n has "bookmarked" the pages so all his posts are in order without other's comments. He'll edit them when he's ready, but they won't show as "new" posts so you will have to keep looking for an update.

 

I did the same with my "reconstructed" Build Log of Vulture - I just added posts with titles and added pictures and text when I had the time to do so.

Uri....its great to see how you built the pump.  I held them in my hands at the show and they are a marvel to look at and feel.  The "pump-action"  can be felt when you move the crank.  

 

Thank you so much for posting.  I cant wait to see them on your brig.  You should also start a build log for the entire project.

 

I hope to see you again real soon.

 

Chuck
