I might suggest that your competence level is fine, after all you successfully installed said wind vane, looks pretty sturdy and rather importantly appears to be straight. It would have functioned fine. It's your eye for detail that loses you marks. But seeing as you also own two rather impressive cars, I suspect you aren't going to miss those marks overly much. Without wishing to deprecate Nick in any way, men admit mistakes whereas fools pretend they didn't happen (usually causing a large workload surge for everyone else). Brings to mind a certain numpty of a 3/E I had the displeasure of sailing with a couple of years back, who thought that pressing the centre indicator on a 440V 3-phase contactor was how you test the overload trip on a very large motor.............

But non of that merry band of illustrious folk can go as fast as the greased weasel 

I think you guys forget that I, amongst Doctors, engineers, computer geniuses, plane flying, carbon fibre artists etc, am here to bring the competency average WAY down.  🤣 sad but true. 

My cat jumps on the windowsill to look outside, to see if it's raining.  THEN, it will sit looking through the cat flap until it stops.    Huh, dogs! 

Next time come up with a decent excuse . 

No sure I’d have confessed to that one 

Hope you got down off the ladder before you stepped back to admire your handy work

Not a bad attempt , 😄

We received a weather vane for Xmas and this weekend I found time to put it all together.    stood back to admire my handiwork  Doh !!   now fixed  

Hello All               I also found a bit on the bottom that had been rubbing on the screw head that holds the oil cooler in so I soldered over that as well(Belt and Braces!!) Will be changed to Counter sunk head ones now! Roger
