  1. Frosty, thanks for loving the Trilobites. At this moment I mostly busy to replicate the existing models by giving workshops (Cast In’s ) to friends how went home after finishing, with their own piece of bronze sculpture or device. The models already known like the heel axe, the Venus types, the ammonites, the masks, knuckle bones, fibulas, anvil types etc.. Also busy to build up a stock of ingots made from worn out molten bronze pump impellors to get a good source of pure material. Funny to realise that the impellors pump the excrement’s of thousands of people during their duty in the sewage treatment plant. After finishing my actual scrap sculpture a steampunk shark submarine, I will go on with bronze casting of a face cast of my daughter Lisa.
  2. That’s how I switch from one bottle to the other. Made a T-split from one 66 lbs (because of freezing) to another 66 lbs cylinder especially while running the foundry. Every cylinder got his own pressure regulator, own no return valve, own hose rapture protection and comes out to one flame arrestor behind the burner(s) line. This made me able to change the sources quickly if one of the cylinders is empty without to change connections and tool time (and chilling the ladle). If I see, one of the cylinders are empty, I close the main valve and open the one of the full (new) cylinder, the inner heat of the forge/foundry takes care of immediately ignition of the ‘new’ fuel source.
  3. According to the source, -the blades belong to the compressor side and are more valuable than the ones at the turbine side. Thanks for H&S tips, ones I grind and cut the stuff I will wear at least a FFP3 mask. For me it’s important to keep the sharpness of the blade as long as possible.
  4. Didn’t follow me home, but brought to me by a very good friend of my, - a whole bunch of titanium turbine blades of an Airbus airplane and F-16 Jet fighter. In this stage there already able to grind/cut out some decent letter opener or small daggers but I like to forge them in to more body to make a serious hunting knife or kitchen knife of it. Any suggestions about quenching, hardening, sharpening or OHSAS-issues are more than welcome.
  5. Welcome to IFI, Art Student, Thomas is right and the melting temperature is not also the pouring temperature. That means in my case the melting temperature at 1053°C didn’t mean the super heat pouring temperature at 1150°C. Regarding the soft fire bricks K23 there are strong enough to resist the temperature without physic contact. Remember the bricks are worn able when distressed by contact (in a forge) but quite durable in a foundry we talk about. Have a look and inspiration at the pictures of our foundry. I use the soft fire bricks (1inch) as a flame face with the backup of 2inch 23K ridgediced Superwool insulation. However read the advice and tips in the ‘casting section’ of IFI to be prepared of any other Health and safety item. There are many more items to take care about, because melting and casting of bronze are no ‘Monkey business’.
  6. To return to your original question, to this explanation about the possible use of otoplastics. These hearing protectors are custom molded plastics from your ear canal that are equipped with special filters that allow communication but attenuate the dangerous sound frequencies. I use these plastics in my workshop but also with other filters when riding a motorcycle. The great thing about these plastics is that they filter out the harmful sound, but make communication and perception of the ambient sound possible. To the fact that I have forged and grind 25 years plus without hearing protection, I am now partially deaf. In order not to aggravate this situation anymore, I have been wearing this PPE consistently since the last decades. In Belgium and Holland, the production of these customized plastics costs on average between 70 and 100 euros. But it allows you to continue to communicate and protect yourself. With regard to the source control, I will certainly also use it, fully agreeing with the 'Rubber', 'Silicone' and 'Chain' method, but there are slight doubts about the 'Magnet' solution. If the average noise level in your workplace is higher than 85 dBa, it is recommended to wear hearing protection anyway. There are currently lots of free Apps for your smartphone to download, so check out Play Store for an application, I compared these outcomes with a calibrated dBa meter and found that these apps are fairly similar.
  7. Will framed this in the shop and looking up to them. Wise words. Thanks for your replay and encouragement.
  8. DearJHCC, to take away some worries and a short explanation. As you can see on the pictures, it is about busbars from a discarded control cabinet. These are usually made from low-alloyed or pure copper. Here there are only traces of some alloying elements such as nickel, cobalt aluminum and sometimes Beryllium (0.4%). With real Berilyum copper there is> / = 3% Beryllium which is used in spark-free tools, is very expensive and actually very dangerous for your health when machining or forging. See the Wiki link. At the start of my foundry activities I myself made my own bronze of 9 parts of busbar and 1 part of tin. https://en.wikipedia.org/wiki/Beryllium_copper 2.1285 Becopper.pdf
  9. Use this on all my anvils works fine. But allready shown in the post Marc mentioned. Good luck.
  10. Hi George, I m glad that in addition to the pieces of forged ironwork (flemish poppies) you have found something else in the work that interests you too. I also collect (and as a German) a collection of old paper money and coins from that time. That is also the courancy and the chance to trade these artevacts. You are right, the bell itself is a discarded oxygen cylinder and not a projectile. This is another metaphor to recall the green + cross poison gas atects that were conducted during the battles at Paschendaele (Ypres) in this days. Glad to hear that you have served your country as an LC, respect, I myself have never had to serve with a broken neck (diving in shallow water when I was 17). This was the reason that I now have to earn my money with an office job instead of staying in a workshop every day. Cheers, Hans
  11. Thanks for your feedback, that means a lot to me. The comments show how well and deeply the images are viewed. Aric - in fact, special locations, for example, the ant was shown in the tiled basement of an out of duty slaughterhouse. Here still the traces of the activities (withdrawn blood on walls and ceiling) present. It was like a scene from the movie Saw. George -you have very good eyesight it is a German 77mm obus that is part of my bell sculpture Ypres 17/18 together with a gun barrel of a Mauser rifle. As you can see on the photo, it was fragmented and completely empty. Unbelievable how the Flemish clay has preserved the details, so you can still read the time scale and 'Reichspatent Doppelzunder' on the igniter itself after more than 100 years. The origin and intention of the sculpture is described in my blog of the website of Forge Furnace Tumulus.
  12. Below some atmospheric impressions of the demos, exhibitions, events and vernissages in which "F&F Tumulus" participated in 2019. Highlights include, for example, the Demo-forging in Tongeren under the feet of Ambiorix, a three-day event in a castle transformed into an art oasis, and an underground event in the heart of Liège in the catacombs next to the river Maas. The result for the necessary use of "blood, sweat and tears" was a lot of attention, many positive reactions and above all a lot of interaction with the audience present . A number of interesting leads, invitations for 2020, and a broadening of our network resulted from this. Portfolios of the various collections (Steampunk Lamps and Animal Collection) have been prepared. Wish you a lot of entertainment when viewing the photos. Cheers, Hans
  13. That looks very good to me, a nice blue print to deserve. Searching the schema for hose brake protection and flame arrestor (despite of the discussion if there are necessary for Propene or not, -in the EU they are still common practice and I use them on my gassers and furnaces) Good luck and Cheers, Hans
  14. After my humble opinion, the best tongs to hold a work piece while forging -are still the blacksmiths hands. Please have mercy with my simple mind. If I start forging happens this always with a save overlengthen of the work piece in question to handle the stuff as easy as possible. But first in the end and after cutting in to size my tongs will be used.
  15. Tube is welded to the scarify plate (incl. Inconel grill bars in air supply <1/2 inch gaps), plate and tube stomp is threated with 4 bolts to the brake drum. Increase the length of the air intake from the 2 inch tube (feed by hair dryer) up to 20 inches because of the crawling up heat. Regulate ember nest and air flow by blow switch position of the hair dryer and an open ash dump + soft extinguishing the borders of a to big fire by water soaked rag fronds you already know from my fire keeper set. A stable clinker poker take care of the rest. Regarding the legs of the forge stand, I simple use some bended leftovers of vertical balcony fence bars I use ones for another project.
