Can it still be saved?
Michael S.:
Hello everyone,
At an exhibition, this cylinder was in a box with other junk. I bought it because the small valves were interesting to me. The cylinder with the two covers is actually complete junk.
But maybe it's better not to throw it away.
I first sealed all the holes and then smoothed the surfaces.
The bore is 25 mm and I think it belongs to a Stuart 7.
Then I searched through my collection of blueprints and found this blueprint. From France or Switzerland?
I think it might work!?

Looks like it had been butchered pretty badly, but still saveable!
Michael S.:
I imagine the glued screws will also hold up under steam.

You certainly like a challenge Michael and yes, it would be great to see it used rather than scrapped!

To add to this: When you look to save a piece it is important that the "plugs" used to fill any problems are made of the same material as the item being repaired. So when you do any further machining both the plug and the casting material is of the same hardness. So for a Iron casting you should use Cast Iron.
Then we need some means to secure the repair piece in the original piece and it must be suitable for what ever it is going to be subjected to once completed. Some of the Loctites are good for the temperatures that a steam cylinder operates under steam at, but check you have a suitable one. Brazing Cast Iron needs a bit of practise :paranoia: but can be done. JB Weld does not have the same strength as some of the loctites but can cover a multitude of sins.
Bronze castings are much easier as you can just silver solder on another bit, but years later you get a dirty black line from the silver :-X
