[Elecraft] K2 Miscellaneous Build Questions
I just started building a K2 and I have a couple of questions: 1. On the Control Board, when I installed capacitor C4 (0.47 microF, monolithic cap 474), it somewhat overhangs and touches diode D1 (1N4148). C4 is a rather thick (fat) capacitor and there doesn't seem to be any way to install it without it overhanging and touching D1. Is this okay? 2. After getting through pg. 14 and most of the capacitors on pg. 15, I noticed that my new diagonal cutters (bought from Radio Shack) are slightly magnetic -- that is, they attract and pick up the clipped leads. I have of course gotten rid of them -- but do you think that using those cutters could have damaged anything? Fortunately, I had not gotten to any of the ICs or transistors when I discovered this. 3. Why is it after getting all the way through pages 14, 15, and 16, it appears that there are more components than ever remaining to be installed?? Do they procreate at night when I'm not looking?

The bodies of the components can touch without any problems. They are very well insulated! 2.

Magnetism is *not* a problem. What is a problem is electrostatic charges such as are caused by walking on a rug, petting a cat, or just existing. This is why you should use an antistatic wrist-strap and mat. But magnetic tools will not hurt anything in a K2. 3.

RE: [Elecraft] K2 Miscellaneous Build Questions
Hello Jon: Regarding question 2; magnetic tools will *not* hurt your K2. Indeed, it's useful to have some magnetized tools for installing/screws from some of the hard-to-reach places. A magnetized screwdriver will hold both a screw with a lock washer while they're being positioned and threaded into a hole. Perhaps you (like me) once worked on a lot of devices using magnetic tape (or, today, disk drives). In those situations magnetized tools are 'deadly' to performance and can destroy data, but they're FB in an Elecraft rig. I'd be very surprised if the cap touching the diode was any problem but I'll leave the definitive answer to question 1 to Don or someone who has built a K2 recently. It sounds like there have been some changes in parts in recent years.

3. Why is it after getting all the way through pages 14, 15, and 16, it appears that there are more components than ever remaining to be installed?? Do they procreate at night when I'm not looking? Yes they do procreate. When I built my K2 I woke up about 3 AM, went down to the shack and found various components doing unspeakable things to each other. Several were already finished and smoking cigarettes. Took forever to get that rig built. -- View this message in context: http://n2.nabble.com/K2-Miscellaneous-Build-Questions-tp684098p684168.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 Miscellaneous Build Questions
Jon, It is OK for the component bodies to touch - yes that capacitor is large. Magnetized tools are not a problem - it is electrostatic charges that can cause problems. I do not like magnetized tools on my workbench since they do tend to collect things such as cutoff leads which I find annoying - it would especially annoy me in the case of cutters. When my screwdrivers get close to things like a speaker magnet, I need to spend a bit of time de-magnetizing them. If you have an old Weller soldering gun, it can be used as an effective de-magnetizer. Just insert the tool into the loop between the two arms that hold the tip and turn it on - wave the tool back and forth for a bit and then slowly remove it at least 2 feet away from the gun - you can then remove power from the soldering gun and you will find the tool has been de-magnetized. You must have a tip (or a loop of wire) mounted in the soldering gun to make a continuous current for this to work, you will feel the 'buzz' in the tool you are demagnetizing. Have faith, the parts do not actually multiply (it just seems so). As you progress, you will see the number of loose parts slowly decrease. 73, Don W3FPR Jon Perelstein wrote: I just started building a K2 and I have a couple of questions: 1.

Re: [Elecraft] K2 Miscellaneous Build Questions
Jon, You will be happy to hear that the Gang at Elecraft have solved component procreation issue with the release of the K3. However, they seem to have created a new time dimension that causes delivery of the K3 to take light years!
