Rippa Gauges/Fisheries research officer

Eventful morning. Research officer using plastic vernier gauges to measure crays, lools up and states one is undersize, grabs my rippa gauge to prove it..... research officer didnt realise i had previously checked my gauge before using it. Gauge was .87mm oversize. I only use it for opening the fuel cap on boat. He walks back to car to get his so called fancy verniers. Comes back. Measures cray and what do you know its 76.46mm i then produce my trusty BCF gauge and told him thats what i use to measure crays with. We check the rest of the crays as i wright down the measurements he is calling out for his research paper. Then research officer states that his plastic verniers are .5mm out. Anyway he went on his merry way happy with his work. I lost 20 minutes of my life 


just a reminder to everyone to check these gauges. I used moore & wright verniers. Dont use shit plastic ones

 As long as they are over size its fine! Youll kust be chucking back sized crays. .2mm-.3mm over is fine but not .8mm-.9mm not for a $20.00 gauge!

Yep still got my mitutoyo and my M&W measuring gear

I've still got my precision measuring tools from my apprenticeship as a fitter machinist.

However be aware that under the legislation the gauge that the fisheries officer uses is the only gauge that can be referenced to in a court.
If they choose to use a bloody gauge made out of plywood they can (I have actually seen them measure crays with a plywood gauge) admitably it was a long long time ago.

I nearly choked when I read that the gauge they use is to be regarded as the master gauge, talk about making sure that what size they say your catch is that is going to be it.

Plastic verniers indeed, no self respecting person would be caught dead using a plastic tool for precision measurement, however they don't have to worry about arguing their case about what the correct measurement is, the legislation supports their decision on the size.

I guess you just have to hope that when he gets really serious after flashing his plastic badge and using his placcy guestimating device to prove how naughty you are you just have to hope he throws you in his pink plastic cuffs, the ones with the fluro fluffy bits............

 I've had fisheries offer to use my gauge before. 


Does anyone know where the love of god goes, when the waves turn the minutes to hours?

The whole subject of verniers is a bit vexed.

Thu, 2017-01-12 06:09

 From my previous experience in the industry, we started using verniers for the "furries", the ones that were just...either way. You can handle a lot of these in a day, sometimes, it can add up. At the time, fisheries could simply use whatever they were using, and ignore what your good quality verniers said. I actually have a piece of 16mm stainless bar, exactly 76mm long, which was supplied by a machine shop-Mansom Engineering in Geraldton were doing them for the industry as a gauge checker. I still use this to check my laser-cut gauge, wouldn't use those stamped ones which were industry standard for too long.

 Id be more inclined to use a stamped one. Once checked. I was just shocked at the poor quality of rippa gauge

I don't know what a Rippa gauge is.

 We all used the old stamped s/s ones for a long time, industry standard. Only objection to them was that they were a bit light in gauge, and not necessarily accurate--it really was very easy to bend them. And, if bent would tighten up, potential for a big bust. The laser cut ones, can't remember the brand , and I'm away at work,  were of thicker material, laser cut and accurate straight out of the box. You'd have to put it in a vice to bend it. The old stamped ones are OK if you keep an eye on them, just don't even consider using anythng plastic.

And I still have 77mm gauges of both types lying around, glad that crap is over with.

 Heavy duty stainless gauge

Thu, 2017-01-12 09:08

 Heavy duty stainless gauge laser cut to 76mm has flash stubby opener on it. They are no good for measuring crays but ok for opening beer and fuel caps on boat. Made from 3mm stainless.

Research can't prosecute

Thu, 2017-01-12 09:29

Research can't prosecute anyway, even if it was undersize...

Oh yes, absolutely absurd but true!

Typical fisheries...i would have thought all their gear would need to be calibrated. May as well have used his dick to measure.

Im sure the kind officer would have had the same attitude if you had made a mistake Bryce.
