Unfortunately not, but trying to find out. It came through as an email.

Do you reckon the knocking noise would have been very loud?

[rufustr]

Probably only knocked once.:o

Last time I saw that kind of damage was on a reciprocating ethylene oxide compressor. The compressor had a 36" diam. piston attached to the connecting rod with a single nut. (two part connecting rod, the part attached to the piston did not pivot) The nut back off while the compressor was running and eventually dropped off in front of the piston. There want enough room for the nut between the piston and cylinder head at TDC.

As slow these engine runs, roughly around 100 rpm... I didn't think it would knock.. If it did, I guess it would be a one big loud ch-clunk, and that'll be it..
I could imagine it can be felt thoughout the ship, as well heard..

Damn, 36" bore?.. thats a big'un... compared to my air compressor, which it have like 2-1/2" bore..

Ever heard the story of the giant ship engine that failed? The ship's owners tried one expert after another, but none of them could figure but how to fix the engine. Then they brought in an old man who had been fixing ships since he was a youngster. He carried a large bag of tools with him, and when he arrived, he immediately went to work.

He inspected the engine very carefully, top to bottom. Two of the ship's owners were there, watching this man, hoping he would know what to do. After looking things over, the old man reached into his bag and pulled out a small hammer. He gently tapped something. Instantly, the engine lurched into life. He carefully put his hammer away. The engine was fixed!

A week later, the owners received a bill from the old man for ten thousand dollars.

"What?!" the owners exclaimed. "He hardly did anything!"

So they wrote the old man a note saying, "Please send us an itemized bill."

The man sent a bill that read:

Tapping with a hammer ......................... $ 2.00
Knowing where to tap .......................... $ 9998.00

Scary thing about the product being compress is that it doesn't need an external air source to burn, it supports it's own combustion. I was helping with an optical alignment of the compressor the day before it let loose.
