    Screwdriver Materials Advice

    Depending on degree of use and size, O1 (also known in the UK as silver steel) is my preferred choice for beginers and on, It can be purchased in short lengths (12" or 36") in ground finish round bars, Heat treatment is straightforward, and predictable, especially if making item for a client. I have sometimes made them from "mild steel" and case hardened them.
  2. The options are there to discuss with clients who want bespoke/commisioned items , and are things to consider when discussing the clients options. It's part of the service that sets our products apart from store bought items, they are unique and designed to solve the client's problem/requirements whatever they may be.
  3. Nice job Aus, often the part the item has to play dictates the relationship of motif to handle eye, and also the working end alignment, Things to take into consideration are Is it a seperate item, If it is to be suspended how and where, it could be vertical on a wall, part of a companion set, laid down or on andirons, All situations have a bearing on the design being used. To sum up, position is relative to function, make them to suit
  4. Don't understand this social media stuff, but found these little beggars happily "TWEETING" from my workshop website.
  5. No thanks needed, but is appreciated. I cannot claim it as mine, as it is one that used to be in common usage, and has many varients, and is particularly easy to do for newbies to achieve getting an impressive look, with minimum effort. It is a good way to introduce them to the difference between forging and forming, how to take long and short heats, the use of a vise, and a simple bar toform the twist,and how twists can be affected by heat dissipation making them uneven. Enjoy and have fun.

    A question from a young man

    I don't know if this is still relevant, but investigate the tax situation in France with regard to being registered as a "Blacksmith", or an "Artist Blacksmith". Apparently the Blacksmith is liable to more taxation and legislation then the Artist is. This was brought home to me by a student who had gone to France and decided to set up alongside his partners work project as a Blacksmith. When he found out about the Tax situation, he came back and took a crash course in Artistic Blacksmithing, and then rebranded himself back in France.
  7. Agree with JLP The Tipp Ex product is what I sometimes use, I understand thay are made with titanium oxide content, hence the heat resistance. Traditional brass rule used to have steel wear plates rivetted on the ends to reduce the wear and hence inaccuracy over time.
  8. Looks good, Another half twist , or more are other variations, but I find the one and a half turns are comfortable on the hand. Punch marks are the traditional way of marking key points when forging as they are visible when meatal is at forging heat. Tend to disappear at welding heat, so other methods required then if accurate location needed.
  9. Thanks for all the comments, don't get much time to do bits now I am afraid, bit out of practice. Exactly as you describe. You can see the punch marks I use to align the bar when it is bent back on itself. Bar was marked out at 6" from end and another 6" beyond, Tapered the end , bent the bar back onto itselfto form a loop, aligned the marks and then closed loop between the vise jaws. Heated up the portion to be twisted, then chilled the loop in the water bucket to "freeze" it, Then held it in the vise at an appropriate length with the two bars at 90 degrees to the vise jaws as opposed to holding them side by side within the jaws (as this tend to allow slippage between the bars) Slipped a round bar into the loop and quickly gave it one and a half twists. and straightened it. This feels comfy in the hand, you can put more twists in, and another alternative is to then beat it down along the length making the grip diameter smaller and altering the appearance of the twist too.
  10. I would possibly class these as pokers and some details of them for those that like pics Enjoy
  11. Trying to make steel out of Mild steel ? It is already steel, so what you are doing is starting the process of case hardening (carburising) the existing material by adding carbon to its external surface, you then have to rehat and quench to harden the external surface, and that surface then is normally a wearing prevention surface, and does not make the mild steel into a spring steel. To temper items you have to first harden them and that usually requires a carbon steel. If you are going to use a molten bath to uniformly temper that hardened steel, it will depend on the use for the spring. For watch springs historically we use 48 parts lead to 4 parts tin, and for more heavy duty springs you can use boiling Linseed oil. Both of these methods are highly risky and can be downright dangerous, I would suggest using other methods that can be found elsewhere in the forum as Mr Sells has already suggested, or consult your local blacksmith group
  12. I use perimeter plus twice thickness of metal being used for the collar, and find that works successfully

    Discoloured and pitted metal

    Hi Thomas, Like yourself, I hate using the angle grinder with a wire wheel and have found a solution I am a lot more happier with. What I am using looks the same, but in fact is a car bodyshop buffing/polishing machine. The arbor is the same as the angle grinders, but it has a variable speed control between 500 to 3000 rpm. Still have to treat it with great respect, but not so prone to flying wires.

    Thanks, inspiration from somewhere on the net, not sure who, with my own spin on them, the snowflake and curlies were quickly snapped up, much to my surprise,

    Christmas items 2018

    Some from last year, tree ornaments and a wreath hanger. Wreath hanger can also be made with an extended top piece to fit over the door itself The hanging s were made from welding rods that had got past their use by date and the coatings were damaged. Easily made and not a lot of heat required.
