Hello
Again, thank you for your comments. Just to be clear about that: I always do some finishing work to the soldered joints after soldering. That Is why all these joints look that nice.
But it is true, I seem to be a little talented with silver-soldering. (Or do I just have the right equipment?
)
It was/is also fun for me building that boiler. And I myself really am into these details that make the boiler look like id does (wooden handles, ...)
I found a picture from the main steam valve, though the picture is a little blurry. I then started building the doors of the reversing chamber. You can see my idea of how to do it on my scribbles that I made.
The doors are bent from 1mm brass sheet. Unfortunately I cant remember how I did this.
(well - its six years over since then) But i must have used some kind of round thing to form the radius. What I do remember is how I made that step into one door: I clamped the door in a vise and then made a square bend. Then I clamped it on the other end (while that was still beeing a little longer). To bend it back, I used kind of a wedge shaped tool.
The static part of the door hinge was made again with my soldering technique (basically a flat piece and two u-shaped pieces).
Oh and in case you need to deburr some holes that you cant reach witch a "standard" deburring tool, you can use these spherical dremel-cutters. They work pretty well as long as the angle doesnt get too big.
The part of the hinge that is going to be on the door will have a tee cross-section. Again it is going to be silver soldered from several elements. But I first had to bend the web for the t-profile. Then I solderd together the web and the flange and in another step added a piece of tube.
After that, I drilled holes into the flange, 4 per hinge. I want to rivet the hinges to the doors. And there are the completed doors (well - almost - I will have to make some kind of a latch)
That is how far I was, when I finished continuing with this boiler six years ago. Well, three weeks ago, I restarted work on it and that also is the reason for this Topic here. I wanted wo write that I was going to continue but couldn't find any topic about my cochran.
Cheers Florian
