Hi
Iv'e been chatting to John Bogstandard and he suggested 2 further things to do to complete the setup. Firstly a steam/oil separator. This does what it says on the tin and separates the steam oil from the steam. They look pretty neat and I think one would look good. Secondly, pipe the exhaust steam back into the funnel where it is re heated and will give a nice effect.
Hopefully tommorrow.
Cheers

Hi
I made the steam/oil separator today. The idea is that the exhaust and steam oil mix enters the separator and is deflected down and towards the cooler side wall. The oil drops to the bottom while the steam exits through a larger pipe and is then piped to the funnel where it is re heated and (hopefully) comes out the top of the funnel as a nice plume. My thanks again to John Bogstandard for his help and guidance.
The chamber is made from a piece of 22mm copper pipe. Turn a piece of brass to suit the internal dia of the 22mm pipe. I used a round profile cutter to give a bit of shape as well.
Test fit a piece of the pipe.
Drill and tap the centre 3/16 x 40. I intend to mount the boiler, engine, separator and lubrcator on a plate of some sort so the stud will be used to mount it.
Contersink slightly to give somewhere for the silver solder to run.
Part off.
The finished base.
The lid is made a nice fit in the tube, nothing else holds it in so give it a bit of weight. This can be any shape you like. Lightly drill the centre.
Use a parting tool to turne to the internal dia of the 22mm tube then part off.
Fill the small recess with flux and a ring of silver solder wire.
Balance a stainless steel ball on top and heat with the torch to solder in place.
The tube and base.
Thread a length of brass 3/16 x 40 to make a stud.
And screw into the base. Apply flux and a ring of silver solder wire in the recess.
A ring of silver solder wire inside the tube.
Flux the base and place the tube on the base. All ready to solder the tube to the base and the stud all in one operation.
After soldering.
The tube is drilled through 3/32 then one side opened out to 1/8. A straight length of 1/8 copper tube is placed in one side and a piec of 3/32 copper tube in the othe. Note how the 3/32 is angled down and towards the wall. Flux and siver solder wire are placed on the inside of the chamber.
After soldering
Brass tubes, one threaded 1/4 x 40 and the other 3/16 x 40 are made and soldered in place similar to the displacement lubricator.
It needs a further pickle and then a polish but this is how it looks so far.

This is fascinating. Thanks for all the pics.
Newbie question...drilled through 3/32 and one side 'opened' to 1/8...
Does 'opened' mean you simply used a 1/8 bit to make the hole larger?
Thanks.

Rich,
Nice work. I am new to all this machining and am quite impressed.
Question,
Where do you obtain your silver-solder?
Here in Germany around the local DIY stores there's only hard silver-solder sold in single sticks.
I am looking for some hard silver solder that is sold in a roll, similar to electonic's soft solder.
Looking forward to getting my mill soon, to be a compainion to my lathe.
Thanks

If you can't get any Silversolder wire locally then CUP alloys in the UK do worldwide delivery. This thickness is good for winding around small items.

Blackgates in the UK sell the easyflo 0.5mm wire for around £1 per metre.

Hi
The silver solder question has been answered George, most model engineering suppliers stock it. I pick it up at one of the exhibitions I attend. Its very economical to use, only the ring of solder placed around the item to be soldered. I have some 1.5mm sticks but find them harder to use and it tends to go where you don't want it.
Jim, I'll empty it with a syringe. It should hold at least twice maybe three times the capacity of the lubricator so will only need emptying every second or third steam up. I'm going to hard plumb it as I intend to feed the outlet back up the funnel.
Cheers

Ha, I've always used the term "Embiggen". I wonder which is correct. ;Dfirebird said:
Excellent oil seperator, I'm (really) posting here so I can find this thread in the near future.
AAAAAAAAAAAAAAAARRRRRRRRRRRGGGGHHHHHHHHHHH!!!!!!!!!!!!!!!
Took it out of the pickle tonight and decided to give it a buff up. I don't know how but the buffing wheel snatched it out of my hands and slammed it into the bench giving it a nice dent and a bent and damaged pipe. :'( :'( :'( :'( :'( :'( :'( :'(. After half an hour of trying to recover it a few choice words were uttered and the separator went in the bin. I'll make another one but not today.
