Have been playing a bit on a new job. Ex Sydney harbour river cat in for some tlc. Have to remove the props, shafts and couplings. Got the props off, split the couplings and, where's the coupling spanner, no one knows. Measure up the coupling nut with 4 holes, back to the workshop and presto new coupling spanner.
New spanner body from 25mm plate, holes drilled for 10mm pin punches.
Also vessel engineer managed to damage three bolts for the couplings, so it was decided that they would be replaced. Got three bolts from a bolt shop and measured the original bolts only to find they are fitted bolts. So material arranged, delivered that night for machining to be started the next day
30mm hex bar cut to length.
Relief and machined along with center hole.
Shank and threaded section machined
What we must achieve minus the damage.
Three are damaged so I thought that a spare would be advantageous in this case.
Managed to get them all done and not stuff anything up, so ended up with 6. Ah i didn't notice my safety shoes in the foreground
