| With regards to Emmons PP guitars. What is the grub screw size used for collets and bellcranks? i.e. What description should I give to my fastner supplier? |

| I think he means a setscrew. At any rate, I believe they're a 6-32 x 1/8" size. |

| Yep, that's a grub screw. I think it's a British term. Great question, I was wondering the same thing....that's the size for the screws that come loose and cause my bellcranks to slip on the cross-shafts? |

No wonder the British army was defeated here by a bunch of farmers and squirrel hunters! 
(Oh puleeze...it was just a joke.  I've had enough death-threats today.) |

If you can take one with you it would be best.
Sometimes they are 8/32. But I don't have a Emmons to
look at.

That wasn't our REAL army, it was just convicts and undesirables. The plan was to let them loose and get assimilated, it worked.!! |

Things sure can drift off-topic here in a hurry. I've never heard of this term, and I'm a truck mechanic. Always called them setscrews 'cause the screw-tip had a slight dished-out/scalloped area to lock it up as it compressed against a shaft, keypin, or wedge-- leaving a round groove or half-moon mark(s) in the metal it was twisted against.
BTW, isn't the term for John Deere tractors "Johnny Popper"  Guess terms get twisted when they 'cross the pond'. Ya'll know what a 'bonnet' is, right?   |

I think that 'Grub Screw' is the European Standard Description, Click here
As for Poppin' Johnny, I got that colloquialism from a Frankie Miller album track.
:-
SLP-339 - Blackland Farmer - Frankie Miller [1965] Blackland Farmer/Too Hot To Handle/Big Talk Of The Town/Poppin' Johnny/Out Of This World/Little South Of Memphis//Family Man/Fifteen Acres Of Peanut Land/It Took A Lot Of Love (To Let You Go)/Truck Drivin' Buddy/Strictly Nuthin'/Baby Rocked Her Dolly
also a single as :-
Frankie Miller-Starday-457-Poppin' johnny/Family man (45)
Maybe terms get just as twisted when they cross the State Line ? |

| I googled Johnny Popper, & Poppin Johnny--BOTH refer to the distinctive 2 cylinder sound of the tractor's engine (each fires at the same instant instead of alternately--like a BSA or Triumph M/Cycle) Cheers! JON Z |

Thanks folks for the replies. Basil, stop stirring our US buddies up.... no carry on...
My mate Phil who runs a machine shop had a look at one and tells me they are 8-32 x 1/8" long with a W point. How does this sound?
Thanks

Baz,
The Allen Key size that fits the grub screw is 5/64".
That website you referred to earlier lists them as available, but boy are they expensive. If Bobbe Seymour sees that price he'll double his Emmons prices faster than John Davis made it to the whore house.
Cheers

| They undoubtedly are 8-32, because they sure aren't 6-32. Back to the hardware store tomorrow, and I'll confirm this (good thing I still have my receipt). |

I have never figured out why the U.S states fractions like 8/32" or 6/32"
This is the same as 1/4" and 3/16"
I guess I can only be right 16/32 of the time

I think for the same reason that a billion isn't what mathematics term it i.e. 1 million times a million,(one million million; 10^12), but just a mere 1 thousand times a million (one thousand million; 10^9) (It seems paltry by comparison.)That's of course presuming that the "Bi" in billion is meaning that.
Or we COULD go down the road of "Bi" meaning 2 and "Tri" meaning three, then a Trillion would be even less than paltry.
Who decided that a Trillion was a Thousand times a Billion, or is it ?
| Quote: |
Milliard is a French-derived numeral word meaning the number 1,000,000,000 (109; one thousand million; SI prefix giga) and which is used in France, Germany, Italy ("Miliardo"), Russia, the Scandinavian countries (Norway and Denmark) ("Milliard"), (Sweden) ("Miljard"), the Netherlands, Poland and Israel (מיליארד). It is non-standard in American English and is rare in other forms of English. When South Africa adopted the metric system in 1971, "milliard" was recommended by the Metrication Board, but has often been ignored in practice. During the 20th century, the short scale "billion" superseded 'thousand million' to become the normal term in most of the English-speaking world.
"Milliard", or a version thereof, is common to many languages other than American English, where a "billion" often refers to a thousand "milliard" - 1,000,000,000,000.
In financial markets, yard (derived from milliard) is still often used instead of "billion" to avoid ambiguity between "million" and "billion". |
Of course that's not even broaching the subject of "Gold Disks" Here in the UK in the 50's and 60's you had to sell a million records to get a gold disk, 500, 000 for a Silver and 250,000for a Bronze, WHEREAS in the US, just a million dollars worth of sales got you Gold.. a distinctly easier proposition methinks.
