Hi Daniel,
That may be the best running Ruby I've ever seen, and what an awesome plume it was pumping out!
It would be nice to say that it didn't need a lot of work to run like that, but it did. It was a big disappointment for the young lad that bought, it wasn't that it is a poor design, it isn't, and it look as if it had been put together using a knife and fork, the cylinders were loose, screws had been snapped on assembly and not replaced, there were other issues which I forget.
Take care Tony.
