  1. Random thoughts...

    • Everyone needs to try to remember when they were ignorant as all of us were at some point on all things.   How best can we help the ignorant?   Ignorance is not bad it is simply where we all start.
    • Yes.   The younger among us do not have the same experiences we did.   This is always true since forever.   The way people learned before and the way people learn now and the skills that young people come to the table with change over time.    Our job is to figure out how to teach in the current reality.
    • We no longer have to spend days doing research in the library.   Many things can be found in seconds by a smart phone search.   This is both good and bad.   It is part of our current reality.  It is unfortunate and awesome!  I do have a library card and I use it.   I think everyone should.   I do have to say that the library these days is not the greatest place to learn much about blacksmithing.   Though I did borrow a great DVD there!  I love a good novel too.   James Clavell is probably my FAVE.
    • Yes.  There are jerks.   There have always been jerks.   Some of us resemble that remark.   Are you one of them... in your own way?  LawnJockey mentioned arrogance.   I see this at times on this site.   In many cases it is deserved.   In other words someone knows their stuff!!!!   But arrogance and condescending to the ignorant does nothing to help anyone and sometimes just fills up space with useless words that help no one.   Why bother typing it?

    Respectfully.   My two cents.

     

  2. I should be ashamed to admit it (but I'm not), that the "humbug" quote from Dickens is my favorite Christmas quote.  I'm obviously not big on the holiday: 

    "HUMBUG!   Would that every fool with "Merry Christmas" on his lips be boiled in his own pudding...with a stake of holly through his heart!"  

     

    What can I say, I'm a Grinch (to mix stories and metaphors)

    "Are there No Prisons?"    "Are there NO Workhouses!!!????"    Repeat as required.   "Humbug" to taste.  <_<

  3. I have a section of 347 that is basically about a 1/2" thick piece of 6 inch pipe.  Started out as a rough cut ring...   So far I have managed to make it straight and have squared it up a bit.   But dang it is a workout!   It will probably take so many heats with my hand hammer that it will probably be something other than what it is by the time I make anything much from it.   I am not sure it is worth the effort!   

  4. Frosty, any IT changes make me nervous.   But I jumped in the Win 10 pool a few days ago and waited for disaster.    At first my monitor was all effed up and icons were huge and distorted and I could not see or do what I needed to fix it.  After a couple reboots all seems well.  it is a bit different but not too different at all so far.   Take the leap, what the heck.   And mine was free with the PC I just upgraded so that made it a bit easier as well. 

  5. I was expecting to see something that implied a swan but didn't. Are you referring to the shape of the hook itself? If so I'd call it a swan or goose Neck, hook.

    When you say "tips" I take it you mean the very end of the hook, what I'd call the "finial" treatment. I don't see a swan but I may not be looking at it right.

    Frosty The Lucky.

    its blurry and probably small.  Just upgraded to windows 10 and have no idea what I am doing.   But to me the "tip" looks like a swan...  That is the Finial ehh?  Looks like snipping tool worked!

  6. Words mean something, they can also be interesting in how we use them.   I am calling this a reverse S hook with swan head tips.   Please provide pics and names as this post leads you.

    Hate to say it but this may be my first pic post with the new format.   Hope it doesn't suck too bad.    

    And the swan head tips are not so evident... maybe..   We'll see how it works.  

    My intent is not to put tradition on it's head.   But rather to unleash folks art in the form of a pic and allow them to express their personal descriptions of that art.   My art is obviously simple and easy.    

    Well I have said enough. I hope we can all get some cool ideas for our art and maybe some cool phraseology to got with it...

  7. Has anyone ever forged sensitized 347 stainless?   If so is this an issue or not?   I think this is primarily a polythionic acid issue but I am not sure...???   And if you are aware it is an issue is there a heat treat that may solve this problem such as a stabilize or solution anneal?   Just looking for someone with practical hands on experience with this material in a sensitized condition...   :)   Maybe it will just crumble if not handled correctly...????   :(    I kinda doubt it but if no one here knows for sure I will be finding out in the coming days/weeks....   Prior to that it would be good to start out with others learning and experience prior to my experimenting.... 

    Before you ask how I know it is sensitized you can either just take it for granted (my preference) or...    

    Because I know it has been in ~1000F service for many years and that we also have metalography of similar service 347 material that shows clear sensitization as determine by a metalurgist.   

    This is potentially a heat treat question depending on the answer?    But it may be a non issue so I placed it in general discussion.

     

  8. I generally get along better with folks that aren't engineers.  

    Engineers can be:

    • Too snooty sometimes.  
    • Other times not very practical.  
    • Sometimes have no experience using a tool or actually doing stuff other than calling on the phone for people to do stuff for them that they complain about not being correct.  
    • Want to talk about safety and call things out without ever actually having done what they wanna throw the safety card at!

    Anyway...   I have a healthy disrespect for my profession.   

  9. So don't think so much about compression on steel as bad.   Steel is strong in compression otherwise hammers would not work very well.   Ehh?

    Think more about buckling.   Steel is fine in compression as long as it does not buckle.   Once it begins to bow now we are in to bending which is buckling.  

    The shape of steel and how the load is applied have a very great deal to do with how well it will handle compression.    A round bar will begin to buckle under compression more easily than the same amount of metal shaped into an I beam shape or even a pipe or square tube.  

    In engineering, which I are one, it is all about buckling.    Diameter and the distance from the centroid of the material and the direction of force applied make all the difference.  

    Cross braces that prevent buckling are a big help!  That is a huge hint into compression and the prevention of buckling!   I am sure people have real life examples of avoiding buckling with cross braces that can be applied here.   Might be a balancing act but...   My two cents...

  10. I work at a refinery.  We have a lot of bolts around that hold flanges together keeping stuff like gasoline, crude oil and a bunch of other stuff from leaking.  Grade 8 bolts are stronger than 5.   We don't specify bolting based on carbon content for blacksmithing tools... ;o).    Bolting is usually more about strength and temperature and also corrosion.   Higher temps usually mean stronger bolts or bolting that is less effected by temperature.   Hot weak bolts that lose tension under application of temperature and pressure will leak at bolted pipe connections.  That is bad.   There is another thread here that talks about 718 material.   We have a piping system that operates at 1000F and 3000 PSI.  It has 718 bolts that have excellent hight temperature strength.   grade 5s would be bad.  grade 8s would be bad but not as bad as 5s.  718 is great!  As for chemistry you can find that online all over the place as already mentioned.   The other piece is that alloy bolts like stainless will elongate more with temperature than some other materials.   Bolts that elongate too much when heated can be a problem.   It is all about keeping the gasket in a flange compressed and holding pressure of the stuff in the pipe.   And yes zinc or cadmium coating can be a problem at high temps due to liquid metal embrittlement.     This is also a consideration in case there is a fire.

  11. To remove the ash and clinker out of the bottom make a counter weighted flip open valve.   Not sure how to describe it but I think that will be better than a screwed pipe cap fro the long haul.    It has a name but it escapes me.   You can use a spike as the counterweight.

    when I first started the 3 lb crosspien would wear me out.   Until someone more experienced told me that they were getting wore out just being next to me while I was hammering.   My teeth were clenched.   My grip was too strong.   My effort was way too much.   This was early on for me fortunately.   I quickly learned that I needed to relax my grip and slow down and simply be accurate with deliberate blows in the right place with good hammer control.   It quickly got to a point where a lighter hammer was simply too much work.   For me a heavier hammer help me do the work vs me having to supply all the energy.   I would be cautious about letting adrenaline fill this need.

     So, starting out I would focus on hammer control using the least amount of effort physically to get the job done.   Let the weight of the hammer do the work while you guide it.  Get the most out of the rebound such that raising it up is the least effort possible.   Raise it high enough to make a deliberate, accurate and effective blow from the weight of the tool.   Avoid short tap tap tap.    My main point is to preserve your body by making sure the tool does as much work as possible and that your body only does what is necessary.    There are all sorts of threads about heavy hammers vs lighter ones.   Main thing.  Let the tool do the job not your body.

    And yeah that cut off hardy made me nervous just looking at it sticking up!

  12. Hey, all.   I loved the tone above.   Just read through it all.   We teach on this forum.    That is what this forum does for so many.  Teach.   

    Teaching is an art.  Tone is important.   Especially on this forum which is all about typed words.   Typed words can be misconstrued in regard to tone.   I think we all need to be cognizant of that.   If someone is doing a dumass dangerous thing our tone needs to be appropriate.   

    I dunno, I guess I am saying that if folks are going to put forth the effort to reply to a question then we need to consider ourselves as a teacher that wants our student to learn and we have to be very thoughtful (and this may take effort on the teachers part) to understand how to help.    For me it is up to the teacher to do that.    On the other hand a teacher needs a willing student.   If the student is unwilling then why waste our time at all?  Don't even reply.
