Just a guess:
But Elecraft probably does not manufacture the knobs (probably supplied by a vendor and it is they who selected "English" sized Allen screws. This not particularly unique in products I have recently bought (though a little irritating when you are working on them). Case in point: my wife and I decided to purchase some inexpensive ($200) bicycles for a little recreative exercise. The handle bar was out of alignment and required a 5mm Allen wrench while the seat clamp was English sized (Schwinn Bike). Fact of life in the USA, today, is the mix of the two standards. Even ran into this on my "Toy Auto" Tundra pickup ;-) 73, Ed - KL7UW ------------------------------ Message: 32 Date: Sun, 9 May 2010 08:47:38 +0000 From: David Dunn <[hidden email]> Subject: Re: [Elecraft] [K3} Help, hex key for split knob To: "[hidden email]" <[hidden email]> Message-ID: <[hidden email]> Content-Type: text/plain; charset=ISO-8859-1 I cannot imagine it would be hard to buy imperial measure Allen keys in USA ! Even in VK land where "standards" of measure are very dubious.

Now, go in the ironmongers for nuts and bolts and the odds are you will find them with BSW threads, a size now very difficult to get in England where they originated! I wonder why Elecraft used "inch" measure Allen screws?? when all the other threads in the K3 are metric.- Perhaps they had similar problems! 73 to all from David VK3DBD 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-600w, 432-100w, 1296-60w, 3400-fall 2010 DUBUS Magazine USA Rep [hidden email] ====================================== ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

There is a difference between "English size" and "Metric size" standards. In my experience, the K2 main knob uses a 5/32" hex key (a.k.a Allen wrench) with no problems. Didn't have to trot out my Metric tools. > This not particularly unique in products I have recently bought > (though a little irritating when you are working on them). In addition to my "regular" tools I've owned a set of Metric wrenches and sockets ever since I got my first Volkswagen in 1970 No big deal. There's no such thing as a Metric Crescent wrench.... :-) > Case in point: my wife and I decided to purchase some > inexpensive ($200) bicycles for a little recreative exercise.

And the Tundra is a Japanese vehicle regardless of where it's assembled.

Hi,
I don't know what all the fuss is about, you guys over the pond have been metric for years! What about 9 mm ;-) Cheers, Vic G7PYR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Just a note, what you describe as 'English size' is actually officially know as 'Imperial'

If it was an "English size" small screw would it not be in the BA
(British Association) standard thread form? But BA was metrically devised. 73, Bob K2TK > > There is a difference between "English size" and "Metric size" > standards.

It could be, but we mostly use metric now - unless of course you're like me and have drawers full of 0 - 8 BA screws, washers and nuts!

Glad to see you clarified the terminology! I specificaly said Imperial
and someone started talking about "English" BA is actually Metric simply because in spite of it's name it was a thread invented in the 1880's (approx) by Swiss clock makers. a easonably fine thread with steep sides in order to give better strength in thin metal . Think about it - it makes sense. Regreftfully they are very hard to get these days as I have found to my chagrin in my key building hobby. British threads per se were BSF, British Standard fine and Whitworth a course thread ideal for Cast iron or soft metals. With minor differences that has the same thread pitch as UNC except for half inch. But due to a shaping of the top of the apex they are not always reliably intercahngeable. There is more to it but not worth the details on this forum. David VK3DBD/G3SCD.
