Solar.

It's fingernail polish remover, which is acetone.

Yes, indeed, though it could be ethylacetate, too. I didn't want to say the word "acetone" in order to avoid that some brothers get a nervous breakdown again. ...ooh yes, now I now,what you mean...I wrote "nail polisher" :lol: yes, I meant fingernail polish remover, thanks GSP!

I had thought to myself, before I posted on here, these boards MAY have a collector value, however after researching for 6+ hours on a few of these boards.. I have turned up no info as far as similar boards to even being able to place a value on them.. so I knew I would not getting pushed around for any reason (not everyone are honest people) . Knowing it wasnt easy to find info on them, I figured I had some rare pieces here. So I said forget it.. I originally got this equipment to experiment and educate myself on the whole refining process..from start to finish. I am going to stick with my guns and completely strip every last part on these things and start educating myself and possibly my kids too. Once I feel I have a good grasp on the whole process from start to finish.

I have seen a lack of our more experienced refiners refer you to any materials for education or safety, but being in the military the saying is “Safety is everyone’s responsibility”. So I will say that you need to read about the processes that can be found in the tutorials section. You REALLY need to read the safety section, and it might be good to leave the kids out of the refining hobby. I’m pretty sure I have read from forum members post that he quit refining for a while because a neighbors kid got into his chemical closet, spilt HNO3 on his skin, and lost a lot of it (his skin). Maybe this was Geo’s story?

Refining is a fun hobby, but can be dangerous. Read a lot before you try anything and after you have absorbed all the knowledge try small experiments, because undoubtedly you will be the next “I have a mess, how do I recover my valuables?”

I do not say this to be mean, I have been reading for nearly a year and still have not tried any processing. (Not easy when you are in Afghanistan)

Thanks, I too am a a veteran. I have tons of time on my hands (unable to work) I am referring to children that are much older than rug rats running around, ect. Safety is a priority to me as well.. I am by no means planning on purchasing chemicals until I have a better understanding about everything. I understand this is not an overnight process.. Its going to take me weeks alone to break these machines down to the boards, Let alone anything further.. In my down time I will continue reading and educating myself.

hedrick,

Welcome to the forum, and thank you for your service. I'll give you some links that may help you in your new adventure.

Read EVERYTHING in the Safety section of the forum, especially the Dealing with Waste topic. No amount of precious metal is worth jeopardizing your health or the health of those around you.

Follow the Guided Tour created by LazerSteve. It will provide an introduction to the forum and numerous valuable links including the General Reactions List. Be sure to follow the link to his web site as he has many outstanding videos, a collection of great reference documents, and he sells a lot of the supplies needed to get started including detailed instructional DVDs. Samuel-a also has a lot of videos, guides and tutorials at his web site Gold-N-Scrap.

Download C. M. Hoke's book. You'll find links to both screen readable and printer friendly versions in my signature line below. You'll see her book mentioned repeatedly here on the forum for good reason. It is probably the best book ever written for the beginner who wants to learn refining. It is written in layman's terms and will provide a solid foundation that will help you understand everything you read here on the forum. You'll also find a tremendous amount of information in the two Forum Handbooks compiled by aflacglobal, Forum Handbook Vol 1 and Forum Handbook Vol 2.

That should get you off to a good start while you tear all that stuff apart.

Dave

A message that hits home hard with me. This was something I was going to get into with my father also but regretably he passed away a few months ago when I was in Fort Hood.
Well being no longer rugrats then they would be a fool not too try to learn this and spend the time with you, good luck and have fun. :|

 

[solar_plasma]

Perfect introduction, Dave!

This one should be showed automaticly each time someone new is joining, - I would have appreciated it, when I came here :lol:

Maybe there should be a link to Testing Precious Metals, too?

 

[moose7802]

That should get you started and of course always practice proper safety

I had said in my first post to practice proper safety and that means if you do not know it you should probably read about it.

My thread was not posted at any particular person moose, but saying "and of course always practice proper safety" is a lot different than how Dave put it in a nice to read post with hyperlinks to all sections.

Dave I agree with Solar completely.

That's a great intro post.

As do I. Dave has a way of doing that and making people feel comfortable here. I know he did for me when I first came here

I want to thank everyone for their input!

I am sure I will be speaking to each of you again soon...

I already have MANY questions going through my head when looking at all of these boards & components. However; I am going to attempt to do my due diligence & try to research my own questions I keep asking myself before I bother any one of you... As I am sure I will learn more along the way doing it this way. :mrgreen:

 

[hedrick84]

I keep looking at these boards I've acquired (pictures in previous post on this thread). As I have been reading through reference material including the forums, videos, & various websites. A problem I have noticed that I am running into from these in the last few days during my research is..Most of references speak and show only the modern circuit boards and components recovery on these boards & electronics. (which is great to know too!)

As you can see in the pictures I posted, These boards are considered vintage. On the white in color boards, gold is on the one side.. what is that silvery shinny stuff on the other side of the circuit boards???

The same colors appears to be in & on several of the IC chips too on other boards in this batch. The appearance is just a very very shiny silver/chrome in color. Not dull like aluminum or tin, again these things are very old.. after this many years.. tin or aluminum would start to dull even if it was polished at one point in the beginning of its lifetime..

Does anyone know of reference material in regards to older type circuit boards, including the older components attached to various boards? As I am sure, the components are called the same names. However; they completely look different.

If I am posting these types of questions in the wrong section.. please let me know. I figured it would be easier to just go ahead and ask here means the pictures are already uploaded on this thread.

Thanks in advance again guys!

That is plain lead-tin solder. If kept in a dry protected environment solder doesn't tarnish noticeable. Just take a look at the solder points around the pins of the components and you see it.
