Solder

10 posts in this topic

metal repairs require strength here are a few things that will be a good thing to have on hand.

 

these will also solder together dissimilar metals like brass and cast iron steel and brass etc.

 

some example would be a broken front pistol or rifle sight broken triggers that would need hi tensile strength solder.

broken handle of a cast iron pot

 

permanent connection of electronic or electric wires or spliced steel cable {making eyes on a wire cable}

or making it longer by splicing 2 short pieces together.

 

80 pa Homogenized solder can be found at brownells.com

 

First this solder is LOW TEMP Homogenized sloder 16,000 psi bond taking a mere 425 degrees to bond.

 

as far as I can see this is perfect to repair broken metal parts

 

Hi force 44 solder takes more practice to use and you need to use COMET flux.

Homogenized solder has the flux premixed.

 

TIX solder it is a great loer temp solder operating at 275 degrees but it only has 4,000 PSI  use TIX flux with it.

Other components that may be very helpful would be heat control past

 

Metals need to both be the melting point of the solder or you wont get a bond small parts are easier to get to temp.

 

using a pencil and scribing a line around the area you do not want solder to creep to also heat control paste

the area needs to be clean use trichloroethane or  alcohol to remove oils hand or machine oil.

A hot piece of metal formed into a IRON to transfer heat there are also miniature propane torches I would use a 

or have a pencil torch they use cigarette lighter propane and are refillable.

 

a simple disposable bottle type torch using propane can be used as a room heater its heat can be enhanced by

heating a piece of steel plate stand the torch and move the plate to the flame you can use bricks to hold the plate.

 

remember heat rises so it takes more heat to solder the top of a barrel pipe etc.

 

this can also be used to solder handles on tools like a cross handle on a shovel you need of course to notch

them to a perfect fit as possible so as not to waste solder and the joint will be stronger.

 

with a few tools re-purposing electronic scrap many solar cells for yard lights are low Ma. output as well as low voltage 

figuring to recharge a dry cell or rechargeable battery you need to charge at a rate < 10% of it's rated Ma. and equal to the voltage a blocking diode prevents reverse discharge when the sun is not powering the solar cell.

 

Right now is the time to invest time in research do some home projects with the kids or learn something different

cruising the net for garbage will not serve you in times of trouble keep a notebook I like to use the bound composition

type.

 

it is hard to remember all of the information that can be used in survival and prepping canning cooking etc.

 

I have these note books in different colors and have rewritten and transcribed duplicate information if it is useful

in another topic.

 

Today science make a case that people need to exercise their brain but instead of using an app on a phone

that are worthless new hobbies completely different than your used to start small do not try to build a shortwave 

radio before you have practiced soldering a switch leg circuit on a very simple LED project.

 

And you can thieve solder from PCB boards and soldered wire it ain't easy but survival never is.

 

These are the things you need to be researching using the Internet not looking at PoRn

Here are some survival projects

 

I would ask people to remember that carbon monoxide is deadly if you use this a a heater for a room you need to heat a tube 

that FRESH air is blown through so the heated air is isolated from the actual fire / flame and exhaust like how your home gas central unit

works if you use this in a shop have good ventilation and vent.

For all you bow people you can make arrow heads by cold forging {hammer & anvil} from rebar also consider using spoons and make those into 

arrow heads if they are all the same brand / model they will be about the same weight

 

here is where solder can be a benefit for a broadhead splicing 2 flattened spoons and Wala you solder and sharpen it and you got a broadhead.

 

lead is easily melted easy to work and wheel weights  strong enough to make blunts or target points

 

when making a mold remember sand has air vents by nature if you make a mold thin lines must be radius out from the item about the depth of

a thick razor blade and not qite as deep or else your mold will not fill out look at fishing weight molds to get an idea also these molds can be

used as is like the bullet point can be drilled out etc etc..

Simple Spring steel method

 

you need a pan fill with oil and depending on the shape a grate to hold it  heat the STEEL in a fire get it red to just orange hot now

 

drop it in the oil making sure it is covered with oil it will catch fire allow it to burn itself out you have now tempered the exterior layer of steel

 

through trial and error if you need a coil or small leaf spring it can be made this way is it as good as factory well maybe not but it is fairly good

 

and will last as long as you broke one why not make a couple at once saves time if you ever need another.

a radio that needs no batteries EVER type in Crystal radio on youtube and look at something other than cute have naked women mud wrestling.

 

also can be found under foxhole radio oatmeal box radio and by the way soldering has an application here also.

the fracture resistance of the hardened sample and what is the ultimate strength achieved is important

all metals will harden under specific methods but will they be useful for a knife gun or tool steel

So there is a lot of sweat equity to find a steel is of poor or no use.

Metallurgy is a science and it takes equipment and knowledge / experience Sanmai chromium stainless high carbon and many others can be made dead soft by an exorbitant amount of heat can be formed and heat treated again. 

 

Buying or collecting steel pipe and bar for your purposes before needed is the best anyone can do I have enough to suffice for blades and other uses.

    • have a great time fishing snake...you almost convinced me to switch to linux though cause i am really tired of virus's...
    • I think I am a bit over technologically involved I just noticed I have 4 notebooks and a desktop and mobile phone within 5 foot 2 printers over a dozen flash drives SD micro SD cards external drives 2.5 and 3.5 etc etc etc.... then add in 2 monitors on my desktop a flat panel tv DVD player modem router and I can't count the burned CD\ DVD's  about a 20 gallon tote full as it got beyond me I decided to use old CD\DVD spindles to store my collections of software video and music then security system and my old school radio is tuned to a oldies country station pumping out a old Cajun favorite Jolie Blon by Doug Kershaw and I still haver books and tech journals. Of the computers one each one runs a different operating system and because certain jobs can only work easily with Windows I have one loaded for that purpose. Found I do not care for tablets and I relegate touch screens for my mobile. I plan on going for a few days fishing I think I need a break from connectivity conversation and routine although I really do not have routines varying is the key to keeping the carpet looking fresh  and tires from getting wear patterns, and ever degrading verbal and social skills from interaction with the same people much like child rearing when your best friend and only companion is 4 years old your one tick away from the nut hut. I am glad I don't have to raise children. I would like to have others try a "live" version of Linux boots from your CD | DVD drive and unless you allow it to create a save file once your computer is turned off all is gone no history or much of a foot print for anyone to dig in. this keeps hackers at bay because it is not a system that can be written to or altered a virus could only be placed in memory and as soon as you switch off that has no effect and will not infect your system. One step further I have one unit that has no Hard drive I keep a flash drive handy if there is something I want to save. Live versions can be Remastered or you can add or remove software and create your own version with software you need burn it and run it as a Live version with your specific "profile" for network login etc.  Breaking out learning new skills being annoyed and frustrated with some new medium  I tried oils and clay I tried to create a copy of Rodin's Thinker in miniature  ended up looking like a cow turd the door I painted looked great ! thats the limit of my oils and clay period LOL...I am great with latex though.        
    • honesty   Yup, some people can’t handle the truth!   My Favorite Animal 
      Our teacher asked what my favorite animal was, and I said, "Fried chicken." 
      She said I wasn't funny, but she couldn't have been right, because everyone else laughed. 
      My parents told me to always tell the truth. I did. Fried chicken is my favorite animal. 
      I told my dad what happened and he said my teacher was probably a member of PETA He said they love animals very much.   I do, too. Especially chicken, pork and beef.   Anyway, my teacher sent me to the principal's office. 
      I told him what happened, and he laughed, too. Then he told me not to do it again. 
      The next day in class my teacher asked me what my favorite live animal was. 
      I told her it was chicken. She asked me why, so I told her it was because you could make them into fried chicken. 
      She sent me back to the principal's office. 
      He laughed, and told me not to do it again. 
      I don't understand. My parents taught me to be honest, but my teacher doesn’t like it when I am. 
      Today, my teacher asked me to tell her what famous military person I admired most. 
      I told her, "Colonel Sanders." 
      Guess where the heck I am now…
    • One I have been playing with is called Peach OSI  try either 64 bit the works or 32 bit the works Linuxlite Here is one that has worked on most all notebooks desktops and does it well   32 or 64 bit on this page older notebooks / laptops can use one of the many versions of Puppy Linux it is a matter of trial and error find the one that functions all your hardware and most likely t will be a trial to get wireless working but hard wired is not usually a problem. one area of new Puppy linux versions              another link  
    • I agree it is always good to collect all the information and then try to understand the text.  Many times when reading a technical text or treatise I have to look up the specific definitions so I can gather some understanding beyond my education. and some is not well written so you have to find other texts that may give you a glimmer of direction, I noticed in researching radiological  I became very aware that we are being paper screwed a lot of words and no real parameters as for ranges for micorsieverts Roentgens and a host of other technical jargon but I finally found that 2 sieverts are BAD more is worse !  Strange I could follow William F. Buckley just fine he had a starting and end with a point most of the drivel I read today is worse than my own writing and that is deplorable my sentences are runalong barley can say I use punctuation properly but I do not think in that fashion I type like I think but not near as fast that is why I have read some of my posts and find I lost a sentence ---- makes me have to go back and edit it a few times. As for the Bible no matter how much I read I can always see some other term Idea or relevance to another text in another book of the bible one sentence harbors worlds unseen and unknown and skipped over Genesis 4 WOW the first few chapters hold the history of the world and then you get a copy of the book of Enoch and you find there is another dimension we cannot see filled with beings from heaven and hell duking it out on our behalf truly fascinating and there is way more we live in a very mysterious world and realms beyond.
