You older eggers might remember my constant recommendation of "double nutting"...

RRP · September 30

Over the years I have always suggested "double nutting" your band bolts. It is an old mechanics' trick of tightening the first nut and then running a second nut up behind the first. That procedure will keep your first nuts tight!

This past week I watched a crew from a power line company erect 3 new 225 foot tall electrical power towers:

Trust me ... their precision and teamwork was IMPRESSIVE!

So anyway those huge, heavy towers were secured by merely 8 nuts using compressed air guns with built in torque sensors on their 4 foot square base! And then guess what? Those 8 nuts were each further secured with 8 more nuts! I talked with the worker doing the nuts and he began to explain the term "double nutting" and I laughed and told him I KNEW Exactly what it means!

And BTW these towers are the"tiny poles" as the large directional pole took 200 cubic yards of cement as a
"mere" minimum of 25 cement trucks today & tonight completing a constant pour into the circular steel re-enforced "cage" which will be the topped with a pre-casted piece which has the protruding bolts to which'''"(I bet you know what I'm going to say) 8 +8 more nuts just like the smaller poles!!!

just one nut talking to another ...

Always make sure your partner is OK with it and you have a safe word before you double nut.

Ron it’s probably a good thing the bolts on that tower are not deformed like the ones on egg bands!!!

This article says the practice goes back 150 years.

THANK YOU!

I prefer flange nuts but double nuts will work in a pinch

hondabbq · September 30

Im not that young anymore but I used to be able to do that.

DoubleEgger · September 30

I remember @CTMike talking about torquing bolts/nuts on a reactor to a million pounds. It was impressive.

In aircraft the second nut is called a "jam" nut. Alternate methods of securing ("safetying" in aircraft) are safety wire or cotter pins or, less commonly, special but-locking brackets.

Is this overkill? Will it help? Tired of maintaining the bicycle chain tension.

@Canugghead - I would think in would.

BTW on a different subject - I understand the Canadian postal employees are on strike. Any word on how close they are to settling? My post mistress told me mail is still trickling thru somehow but VERY slowly.

Canugghead · September 30

Sorry Ron, the strike started today, I haven't been paying much attention, yet.

zaphod · September 30

strike started Thursday man

all the carriers were told to turn around and return their satchels to the depot. Nothing is going through. I still have a few bills that come on paper (including one I can't stop even though it also comes in email).

I am not sure anyone will notice. I'm more concerned about the liquor stores and the VSO (Vancouver Symphony).

Canugghead · September 30

Haha you just proved how much attention or lack thereof I'm paying.

zaphod · October 1

like I said, I really don't know if anyone will notice. I'm old enough to remember the days before Canada Post when it was a Crown corporation. Every November/December saw a strike. I lived in Ottawa in those days. It was a national holiday tradition and everyone suffered. Now - not really an issue.

The nylon locking element in the jam nut is overkill. Doesn't hurt a thing except for carrying around a few grams, just unnecessary.

Good eye! Not carrying anything, it's the garage door opener

This is flying over my head. Where, on a bicycle, is the chain bolted down to a bracket (dubble-nutted or not)??

alaskanassasin · October 1

I think he is referring to the size of the chain @Botch

alaskanassasin · October 1

That is belt and suspenders @Canugghead

Canugghead · October 1

@botch, sorry to confuse, it's an overhead garage door opener driven by bicycle-type chain. It literally flies over my head all the time too

I worked maintenance in a commercial food plant for 40 years. Any fasteners over a potential contamination area had to be torqued and a nylok secondary nut was torqued on top of the first. We also used the same procedure in high vibration applications. So no, it is not overkill.

Thank you for popping back in here! It's been a while since you and your friend made it over to the Peoria Eggfest! much less seeing you posting here (unless I have missed them!)

Thanks, good to know. I guess that counts as triple nutting? Right in the same league as three cheeses and triple indirect

Triple nutting? Now you’re just showing off…

Good plan! No one wants to unknowingly swallow a nut!

I wonder if there are videos online showing you how to triple nut.

Be sure to use a Duke University computer when you google that

Relax guys, this is what I meant by triple nutting
