I am about to fit a new anchor swivel. Which of the many types of Loctite should I use to lock the screws?
 
A blue Loctite will be more than adequate. Most Loctites will set underwater.

Why do you want to install a swivel? Vyv has some lovely horror stories on his website, unless you are investing in an Ultra or Kong swivel and a Mantus swivel, being so large, will reduce the ability of your anchor to set.

this does not test the impact of swivels on anchor performance but their are analogies - it tests for different sizes of rode.

There are other articles on swivels - but they are subscriber only :( and none of them are really encouraging (unless its a Kong or Ultra swivel)

My uncle ran a machine shop and used to tell Loctite grades by tasting it from a bit on his fingertip; he's not with us any more, strange that.

From memory on aircraft grade 221 was ' temporary can be overcome with a spanner ' while 290 was ' there forever '.

Of course anything remotely important was wirelocked as well.

290 isn't actually billed as particularly high-strength. Its speciality is the ability to wick. Like most, if not all, of the 2** series, fasteners on which it's used it can be released by heating. (Typically to 250 to 300ºC.) Granted, pointing blow-torches indiscrimately at bits of aircraft may not be a great idea.

Probably not, as when an aircraft had fuel or vapour in it they were worried about my powerful flashgun, and in the paint shop we had to get the sensors temporarily off before I could take pics there - these photo's weren't a whim, Design dept, PR or somebody asked for them.

I asked Metz if their flashguns were ' explosion safe ' - naturally the response was " we'll get back to you " click, brrrrr

Absolutely not

I suggested the milder grades because they are more generally useful than Studlock. The fundamental part of the battle of stopping things from coming undone is preventing vibration, any grade will do that.

I suppose thread drift's inevitable in a thread about locking compounds. Perhaps Loctite have a product to fix it?

Anyway, a more recent hazard from flash is that some hospital equipment (controlled drips, for example) relies on optical sensors. Flash photography really screws it up. Don't ask how I know. (Sorry to have messed up your treatment, James, but you seemed to enjoy that pretty nurse scuttling back and forth to fix it.)
 
Well I'm asking how flashguns knobble hospital kit ?

Why does a controlled drip have an optical sensor ? the ones I've been on were lucky if they just dripped.

I don't imagine it's for frantic waving from the casualty to CCTV or even pretty nurses; ring flashguns seem to be standard in medical photography.
 
Yes I already mentioned those but what are they for and how come ring flash is OK ( hopefully not just post mortem ).

I bet Nikon don't gurantee those safe in an explosive vapour environment either.
 
The optical sensor counts the drips as they go past and feeds the data back to the system. Never heard that flash guns cause them problems, but they may do. It may be a bit like mobile phones in hospitals cause problems with live saving kit, they don't; but it does stop people using their phones in inappropriate places.

I imagine that if a hospital has commissioned pix of live patients on drips, it can arrange to have the things re-set when their alarm goes off. Having random smudgers wandering around hospitals taking snaps is perhaps a little more inconvenient.
 
I can understand ' inappropriate ' - one time at Dunsfold a fireman's wife crashed into a Hawk being towed ( a re-enactment proved it was our, Hawker / BAe's fault, it was nowhere near as visible as we'd thought ) and a supervisor told me to photograph her unconscious over the wheel with crying baby in the back safe but crying.

I told him to foxtrot oscar ' these are my friends ' ! So waited until she and the baby were safely removed by our excellent nurses ( one had been personal nurse to Princess Diana ) then took pics of the engineering aspects of a car - completely written off same as recently at Wittering - hitting a combat aircraft wing...

No doubt a photographer for the Sun or similar would have been all over it.
