  1. I’m ready for serious casting?

    Sold one of the 16lbs melting furnaces on CL and started to build a bigger furnace ‘New style 3.0’ -hope to use them with 2 burners and a A12 or A16 crucible in it. Will build them from thin hard stone refractory tails as direct flame face on the bottom and soft bricks higher up. The backup and insolation will be a 1in Superwool layer. Cheers, Hans
  2. Crucible Shattered

    Hi Mr.Read, I very gentle pre-heat all my crucibles before first melting action. That means put then empty in your furnace and bring the slowly up to yellow-red heat temperature. After that stop your burner and leave it in the furnace to slowly cool down to room temperature. If you start melting ‘full power’ with a brand new crucible I will be an expensive hobby to by new ones over and over again. Another tip for future melting on other materials, please buy a separate crucible for every different material you intent to cast. Reg Hans

    Seen again a lot of precious ‘bounty’ passing by in this post (cranes, presses, anvils, materials). But are the most jealous of the also shown pickup trucks hauling it. Missing my Chevy C1500 Silverado I used in the past for the professional shop very much. However nice to see all the trucks and will suggest to Glenn a new topic ‘Show me your transport appliance’ if it’s not already discussed in some treat from the past. Chopped the bronze pump rotators in to pieces and used the 9in angle grinder after all -and was the whole afternoon busy with ‘ingot mass production’ still 44lbs to go.
  4. Missing part

    Hi, made de little fellow complete, totally forgot my friendly neighbour and his big lathe in his big cellar. He found a chunk of bronze and turned the washer according to the earlier mentioned drawing within an hour. I think he was even happy as I, to use his lathe with a purpose and supply me with the missing part. Will make a nice crafted fire poker for him to say thank you.
  5. Too late for any feint, they have us. How about the forge welding on your forge, also a point that’s still on my agenda. Meanwhile, I have had good contact with a Belgian welding institute that has read an forge welding on a macro etching and electron microscope of one of my forge brother in West Flanders. Want to share the pictures as soon as possible. According to them they not compatible with any conventional welding and his mechanical requirements. Very curious

    Das, in our days it's exist as well, but the pull us through off it (survival of the fittest). In this days, they screen and analyse every think and put you in a drawer of patrons. Lock at our brother Charles. Nice to know that even famous people like an Elon Musk and Albert Einstein and many others suffers on dyslexia and dyscalculic and become genius. Thanks, for the tips gents (Glenn, JHCC) will create a ‘Sollbruchstelle’ (fancy German description) and use the sack and some beams below it.
  7. Is epoxy really needed

    As long as the epoxy is hidden and not visible I will use it. Have problems with my heel axes to attach them to the wooden knot handles (shrinking). As long as I’m not able to extract (get) birch resin.

    Very nice to hear Das, I wish she have an even prosperous future as Lisa (15), my daughter and precious eye apple. Lisa went to secondary art school after school holidays. After discovering ‘dyscalculic’ (like here father) she goes for arts and crafts. So she will never become a smart calculating business-woman but hopefully a creative soul with here foots on the ground (wish she mets jlp some day). Regards, ‘Der’ Hans

    Will try to create a sack from thick towels (asking Diana to sewing one - ..............she hate it) Btw everything as desired with your heir and beautiful daughter?

    Unfortunately also a chronic shortcoming of detached neighborhood children. Only neighbors of old age who sometimes themselves are too weak to push their rollator. LOL Have to do the job by my one and use Iron woodrows sledge hammer or toes
  11. It followed me home

    Unfortunately I don’t play any other ‘instrument’ except the angle grinder. First intention was to cover the pump blades with an old towel resting on an steel/stone plate and beat on it.

    If got bronze, bronze, bronze –about 110lbs. Exchange it for 60lbs pure lead and a delicious crat of Belgium beer. No idea how to get it in my A5 /16lbs crucible!? (smashing with the sledge hammer/cutting in suitable pieces with the grinder?? –with all the loss of grinding dust) Help ………………..

  14. What did you do in the shop today?

    Hi Al, thanks for your feedback, did wat you suggest end let them cool down slowly and will use the coal forge to harden the C45 tool steel they use normally for jackhammer chisels here. After my humble experience only air hardening is not enough. So after heating / forging on the modern gas forge and air hammer I will use the conventional manor again on the coal forge to harden the stuff. So modernism is not everything. See also (if you’re interested) a short article I wrote in the past to convince the local contractors to offer there worn out chisels to my old professional shop. For the rest of the audience please feel free to add or fill in. “In order to extend / improve the lifetime, function and stand times of expensive industrial chisels with a length of ≥ 400 mm, it is possible to re-forge them professionally. That is to say, once the points or chisel-point/cutting edge have worn off, these will be forged back into their original form. After this, the work surfaces (points or cutting) are again hardened and re-grinded. Hardening and grinding are essential as the chisel base material is tough and soft to absorb the blows and vibrations of the (jack) hammer. However, if the chisel were hardened thorough, it would break like a piece of glass. The multiple application of only the grinding of a new point on the soft front is only a solution of short duration once the hardened points or work-cutting are worn out! How does it work? The worn chisel front is brought to a temperature of 900 - 1000 ° C (yellow-red) by means of a blacksmith fire (gas forge) to forge it back into its original shape. The chisel (and only the front -after cool down to room temperature) is then brought to a hardening temperature of 810 ° C (cherry red) to obtain a hardness of use of approx. 55 HRC at the point or cut surface by (short) quenching (in water or oil) and using the rest heat to ‘travel’ to the chisel point (blue running colour) and final quenching to room temperature. With the subsequent grinding / sharpening of the point or cutting edge, the chisel is again suitable for long-term use. The preservation of a chisel is possible several times with only the result that it becomes slightly shorter after a few treatments. TABR provides local contractors and contractors with their preserved and reliable chisels for less than 35% of the new price of a better branded chisel. So contractors, contractors, artists do not hesitate, collect your finished / worn chisels and offer them to the local blacksmith or contact the author of this concise article.”
