[NTLK] :Re: Plan for Performing eMate 300 Hinge Repair

Hello Forrest and Newton Friends,

At this point I am in my getting ready phase.  I have been researching and reading what has been shared about performing the eMate 300 hinge repair here and on what other Newton/eMate enthusiests have published on their websites.

Now I'm looking for the tools that I will need.  If you are like me, and do not have an electrical or soldering experience, use these information and resources that Frorest and Allen have shared.  I feel encouraged that I now have enough information about soldering to attempt the eMate repair on my own.  I agree, if I was doing more detailed soldering work, more information and practice would be required.

I will let everyone know how I make out when I attempt the repair next weekend.

    I would not stand in the way of gaining more knowledge—certainly, Allen’s suggestion that Mr. Grassia watch the linked YouTube instructional video is an excellent one—it is superb, both entertaining and instructional. Each of us no matter how skilled could possibly learn something new—I know I did.

    But regarding the soldering required for the hinge fix on the eMate—I am not being overly simplistic when I say that just touching the hot tip of the iron to the connection will quickly melt the solder and release the wires. And, reconnecting the wires will, as I said before, likely require NO extra solder. Hold the wire(s) against the connector, touch with the tip, and it’s done. My experience was that there was enough solder remaining to easily reconnect.

    It is true that two of the most difficult things to learn in soldering is how long to keep the tip on the connection, then how much solder to apply to make a good union. I don’t believe either of these skills are required for this project.

    Alan is being very brave and I admire him for that. He is taking on a project that for many of us seems trivial, but not if you’re inexperienced. He has identified what he requires for it and I’m certain he will do well. My hope would be that he takes all this advice for what it is and doesn’t overthink it or “psych himself out” over the possibility he will do something wrong.

    > Forrest's instructions are good, but soldering does take practice.  I recommend youtube to see how it's done.  It's easy to use too much solder and make a mess, usually because the solder is hot, but the wires are not hot enough for the solder to flow.  Practice on something that's not an Emate.

    >> Hi Alan:
    >> Yes that one will do nicely.
    >> Hotter is not necessarily better. I have a soldering gun that if I recall is something like 100 watts or more. That will obliterate most simple soldering jobs.
    >> You will find the soldering work to be remarkably easy, and I?m not just saying that because I have experience. Follow the instructions?plug in the iron and allow it to >become hot. It?s a good idea to ?tin? the tip of the iron the first time you use it. This ?tinning? is nothing more than applying solder to the tip and allowing it to melt?of >course, once it becomes hot?then wiping off the excess with a rag. I like to tin the tip a couple of times. A properly tinned tip will conduct heat better and will therefore be >more useful.

Re->soldering is much the same, except you are now holding the wire to the terminal you want to connect with, and touching the hot iron to that joint. In most cases you will >not need any additional solder to make that union.
