I recently purchased a boiler from e-bay which turned out not to be suitable for the locomotive I wanted it for. So I duly advertised it and sold it on. It turns out the buyer has informed me it has no blowdown valve on the backhead. I thought this was a fairly easy fix? I suggested that a hole could be start drilled and finished with a flat nosed "drill" and then sa bush soldered in. Anybody care to comment? Or make altertavive suggestionS would be greatly appreciated. Many thanks in advance. Very worrying!!
We had a Maid of Kent boiler that someone just soft soldered a bush into for a blowdown. Not a good solution. When it came loose. , a fellow club member made a new threaded bush, tapped the hole and, after screwing it into the boiler, caulked it with soft solder. You need mechanical strength so can't just rely on soft solder alone.
Silver soldering a bush into a finished boiler can lead to more leaks than you can cure.
