Hey Bruce, those cast-iron Jensen #25s are about the most iconic, and indestructible, of the entire Jensen line. Wouldn't be without one, or two, or three, or more!

Really nice work you did cleaning that one up!

Didn't hear the video all that well, so could you describe what you did to fix the cylinder side-wall split?

I didnt describe how I fixed it, but I will now, it's called Cyanoacrylate better known as "crazy glue" red Loctite will also work I'm told, I use the "Temple of steam" instructions, run a boiler full of water steamed through the engine without any oiling on the cylinder anywhere to purge the crack, I then (while hot) carefully apply the crazy glue to the crack, use a piece of silicone tube with one end in my mouth and force the glue into the crack while having the steam valve already closed and retracting the piston to the extended position (lest you glue it in place), all this will encourage the glue into the crack fully. Let dry for a day, I've never had to apply more than twice. A common occurrence is that the crack extends into the rear of the cylinder and occasionally you have to hit that area twice, this was as large a crack as I have seen & only took one application. I currently have 5 of these plants.
