Working copper bilge-pump 1820, 1:64 scale

[mir0n]

Many people asked me to share how i build it.

So i have no excuses do not do it....

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

Since I haven't made that mistake yet I have to sit and wait with you for the answer. Since I know that will happen to me for sure.

Very cool pump, amazing at that scale!

 

Now you need to create an animatronic crewman to work the pump in a diorama display, possibly scale figure jointed at the waist with arms attached to pump handle.

Cool!!! It works!!!

The head:

 

 

0.3 mm brass piece: bending, drilling, grinding out a support of handle (have no photo, but looks like everything is clear from the sketch)

 

 

Soldering the 3/16'' tube (with bore for 00-90 thread) to the head cover.

 

 

Inserting the 5/32'' tube into

 

 

Fluting and cutting the threads for the locking bolt

 

 

First fitting

 

 

Soldering the support of a handler

 

 

Chopping, grinding out, trying on

The locking bolt:
 

grinding out the extra thread from 00-90 bolt

 

 

Cutting off, folding for perfection

The “pipe”:

 

On copper tube 1/8'' (main pipe): grinding out a little groove for the locking bolt

 

Cutting off to the size (see the sketch below...)

 

On other side of the 1/8'' main pipe drilling a 2.8mm bore; that would be a place for a ball of lower valve

 

Copper tube 3/32 ""(overflow pipe): Grinding down the desired area up to 1.9mm (see sketch below...)

 

In the 1/8’’ main pipe: drilling a 1.8 mm bore for the overflow pipe

 

Another piece of 3/32" tube and all 3 parts for pump pipe are ready

 

Soldering all together using simple conductor

 

Reseating the soldering of lower and upper pipes with help of 3/32" diamond sphere

The rocker arm ( The handle)
 

Brass 0.6mm: cutting out and forming of the rocker’s sly form

 

Brass 0.3 mm: drilling three 0.5mm holes with 1.4mm step

 

Bending stock holder, whetting the rocker tip up to 0.5 mm

 

Soldering

 

Grinding off excess

 

Handle assembled!!!

 

In handle support: boring a required spot for rocker movements

 

Fitting

 The stock

 

In the strip of 0.6mm brass: drilling 0.5mm holes

 

Primitive: in a vice with help of file

 

Done!!!

The piston

 

Brass 3/32" tube: Boring to 2.0mm

Well, yes! First there was a hole for 0.5mm axle – no photo left

 

Boring the edge a little for the stock move

 

Solder the washer, so that the valve ball is not thrown out of the piston.
Reseating the ball bed with 1/16" sphere inside

And where a photo from the last messages? The pomp and without them looks good, but it would be desirable to look...

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.

That is all

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.

Thank you Chuck

Thanks, Danny, I understood, I will wait. The pomp turned out excellent!

Hi Mirün,

 

I must have overlooked that lovely bilge pump you made last year. It Looks fantastic and is so inspiring that a am thinking about alike....

Well done !

Mir0n, that is a lovely piece of workmanship.
