  1. You are using too big of a hammer for you!  Hammering too fast and not hitting with power.  Your hammer shape seems poor.  Your placement of strikes is not good.  You would do better with a two pound hammer.  A straight peen or cross peen should do most of your work.  You also need to develop skill at using the edges of your hammer.  

    You have lots to learn... some coaching would help.  Try to watch lots of videos and to watch skilled smith’s in person when you can.  I like a two or two and a half pound hammer for most work.  I’m built a little stouter than you.  Choking up on your hammer is poor form when you are trying to move metal quickly.  Figure out where you want to make a strike... then BRING IT! Your doing the typical beginners whackity whack.  Skilled smiths have rhythms more like thumpa thump WHOOMP, thumpa WHOOMP WHOOMP!  

  2. A type of belt that I would really love to source is a good ceramic grit in about 220 or 280.  I can get the 220 from one source but it is on a very flexible backer and doesn’t work very well for the precision sharpening that I want to use it for!  I need it on a stiffer backer!  It seems not to be offered anywhere (I’ve searched a lot)!  I bet there are lots who would use it if someone would make it!

  3. Following up on the bootlaces: my cats have inspired me to develop expertise in repairing the tips!  They are obsessed with chewing them off for me!  I have acquired a kit of various diameters of clear heat shrink tubing.  I can easily retip my laces or make replacements from 550 paracord!  
    BTW I’ve learned that those very long laces on military style boots are pretty handy because you can loosen them without pulling any through the eyes.  Never having to relace  them saves lots of time!  I use an extra tuck on the bow knots and then tye another bow with the doubled bow ends.  That uses up all that extra lace and stays tied all day!  

  4. You guys are the GREATEST!  Storm Crow… that’s him!  
    Velegski, I have some 1090. Yes it’s a good steel for me.  I once made a carving knife from an old hollow ground circular saw blade that was stunningly durable!  Not forged just ground but I did heat treat it.  I tempered it with a tiny flame on a propane torch and incredible PATIENCE!  I got a blue temper at the spine and straw at the edge!  That blade would cut for days before needing sharpened!  
    Thank you Irondragon! 
    What a crew!

  5. Wow!  I guess I piqued some interest!  Thanks to all for thinking and discussing this topic!  We used to have a smith on here that made a lot of large chopping blades and sold quite a few to military operators.  He noted the double quench if my memory is correct.  He used 5160 for most of his blades.  I can’t quite remember his name though.  I asked about it at the time and was explained that it apparently converted more carbon to austenite.  Or… something like that.  I expect that I’ll probably get good results by single quenching and tempering, though.  I want to make a form of hook knife known as a mocotaugan and to use it carve some pretty hard woods!  I might also make some shallow curved hook knives designed primarily for finishing cuts on carved spoons.  
     

    velegski: I am mostly interested in getting a good hardness with an eye to edge retention.  I expect that 5160 will be inherently tough enough for my uses… carving hard woods.  What worries me a little is that I might not get my blades to be as durably sharp as I would prefer.  It is time consuming to produce a razor sharp polished edge on a shape like a hook knife that cannot be fully worked with power equipment!  I mean I insist on extreme sharpness and I disdain softer woods… so I guess that makes me one of those fussy old curmudgeons?

  6. Thank you Irondragon!  I actually have that on my iPad.  I just looked at it though and it doesn’t seem to address my interest in the double quench treatment.  
    Obviously I am using this steel outside of its normal commercial parameters.  The hardness values look good for my purposes though!  Perhaps I will just skip the double quenching?  Around 60 Rockwell seems pretty good for carving woods.

  7. Yes Frazer!  I quench in oil.  I have usually just quenched once and tempered once.  I know that some smiths do a double heat and quench.  I understand the concept of double tempering too.  I’m just wondering about whether to redo the whole quench and temper cycle twice or to skip the temper cycle between the double quenches?  I’ll look for a heat treatment guide… but info from a practical smith working often with the material… seems more useful to me.

  8. I understand that double hardening can increase the hardening for 5160.  My question is: do you then also do two rounds of tempering?  Or just two hardening steps and then temper?  
    What I am really after is optimal sequencing for 5160 steel.  I am making mocotaugans.  Is there any 5160 fans out there with advice for me?

  9. Yellow ochre, pencil lead, powdered graphite... these are common jewelers solutions.  You can use yellow ochre acrylic artist’s paint.  Maybe use a coating or dip and then also put a barrier line of soft pencil lead to help keep the solder from flowing into the clamps?  I’ve had pretty good luck applying a slurry of powdered yellow ochre, it’s kind of an anti flux.

  10. I like your splitting axe!  I just am impressed by the power of a true wedge shape driven by weight and momentum!  Yours looks just about right too.  I do find that the axes in my collection are rarely used for splitting though.  For firewood a maul is better and when I had a bad arm on one side I actually split quite a bit with a heavy duty froe and hand maul.  For more delicate splits... like spoon blanks or tool handle blanks... I generally use a mid size froe.  The small froe is also just the thing for splitting chunks of hickory or pecan for the smoker/bbq.

  11. I quite like the looks of that Ozark hoe!  Personally I’d prefer to make the langets by using solid rod and making a u-shape, like a big staple.  I guess the downside would be that you couldn’t tighten it after the original installation.  If the ends were pointed and bent inward... you could hammer them into the handle and then use wire wrap to secure them!

  12. One wood that no one has mentioned yet is hackberry.  Elms in general are probably good.  The interlocked grain patterns of elms resist splitting and make for strong handles!  Hackberry is particularly flexible and springily compressible... making for good hammer handles that tend to stay tight... I have some that are proven in use!  Hackberry root was a traditional favorite for froe mauls.  

  13. Railroad track is considerably more difficult to bend than 1.25” rebar!  During the civil war saboteurs heated railroad tracks in bonfires and bent them around trees... so that they couldn’t be reused!  It would certainly be possible to make the type of bends you want by using a trench fire.  I suspect that you could coax such bends at black heats far short of red hot!  You might even try cold bending them!  To cold bend use a sledge and lots of strikes... similar to re-arching leaf springs.  A sort of giant bending fork setup on your steel table could also work for cold bending if you use long pieces so that you have good leverage... make lots of small bends... don’t try to get the whole arch at one go.

  14. It’s true that Missouri jungles do not grow padouk.  We do have pecan, hickory, Osage orange, persimmon and many understory shrubbery woods that all make good tool and knife handles.  The persimmon is related to ebonies and commonly used as carving knife handles by some of the local makers here in the Branson area. Redbud, rhododendron and many other small bushy trees are also useful!  Our local jungles are truly RICH in excellent wood sources!

  15. Locust is incredibly hard wood!  I haven’t used it for handles... but I’d say it’s a pretty good bet!  Mulberry is tough and flexible... likely to be good for many types of handles!  I don’t know much about olive, but I would think it has good potential!

  16. Air dried wood is generally prettier and easier to work than kiln dried Thomas.  Still IMO starting green and working the woods right through the drying process is an unmatchable pleasure!  My spoons are carved fairly thin and dry enough to finish in a couple days or so.  For tool handles I commonly use branch and sapling woods that use the natural rounded and sometimes curved shapes.  I no longer worry about drying splits!  If I get some, epoxy or cyanoacrylate (for the very thin cracks) is an attractive fix!  I now subscribe to the Japanese tradition that holds broken and repaired to be superior to unblemished originals!  I will often refurbish old handles on antique, sometimes abused tools... when I might have replaced them more quickly... but they would be less interesting!

  17. Magnificent!  A joy to my eyes!  I am a woodworker myself.  These days I mostly harvest my own from my property.  I only have 1.67 acres here... mostly grass.  Still the shrubs and trees produce more wood than I could possibly use!  Lately I’ve cut some small trees that are too close to the house.  One small trunk of black poplar has been split into eight blanks that have produced six spoons so far!  It is very satisfying to work with froe, axe, knife then crooked knife!  I also enjoy working with a shaving horse and drawknife!  So much more enjoyable than working with power tools!  I am spiritually enriched by your dedication to work in ethical ways that respect the Earth and her bounties!  

  18. WD40 works pretty good for me.  I have some larger plastic ammo can type boxes that have rust inhibitor molded into the plastic.  I have been using them to store carving tools and files. I think the brand is Zerust... boxes by Flambeau.  Similar products may be available too.

  19. For your next one... walnut is a poor choice but ash is fine.  Any hickory is very good including pecan!  I actually prefer green wood for most tool handles.  It’s best to dry it after shaping but before final fitting.  Short tool handles are easily dried in a microwave oven.  Baking in the sun for a few days works well too.  In summer my pickup’s dashboard is a handy drying oven!  Once you’ve worked a lot of green wood... it’s not scary anymore.  The finished products are much superior!  Air dried woods are prettier, stronger, more flexible... basically better in every way!  If I happen to have a handle that splits when dried... I just fill it with epoxy or super glue. The cyanoacrylate (super glue) is for very thin splits that I can’t get epoxy into.  
    Yard trimmings like lilac, holly, dogwood, oak, redbud, persimmon and many others can be good handle materials!  

  20. I have a Pheer  grinder.  I remember the day that I first set it up!  Within twenty minutes I had sharpened every dull blade I could find!  I had to shut it off!  What a feeling!  Have you got some belts?  I had used all sorts of cheap and common grinders for many years... the difference STUNNED me!  You are likely to be a very happy guy!
