  1. I used to wonder what they are for but over the years I have found mine quite usefull. Mine has a dish in it and I have in the past made 1000"s of candle sconses, I use the V and large half round swages for sorge welding sword tips into . and closing bird mouth welsa. The other half rounds are great for supporting round stock that needs forge welding or cleaning up. I have modified the edges of some of the half round swages to use for turning the swaged handles of little blacksmiths knives I make. I have mine mounted high it makes it much easier to work.
  2. I have gad good results grinding surfaces clean at 36 grit then applying wd40 and immediately welding around the billet (MIG). then soaking at welding head and heavy forging under press and power hammer , the important thing is to increase the weld surface area a lot at least double it. i forge strait to finished knife thickness as thick billets will tend to crack the core. Ive also used argon and oil and weld is easier.
  3. This is not a practice I have ever seen a profesional smith working with carbon steel do? or heard of one doing in the modern world...I have come across it in old machenery manuals but assume it is redundant apart from very specific instances (complex crosssectional changes come to mind.)
  4. really goods to see especialy the pedal stop. I really dont like the progression of clamp then light blow - heavy blow on these hammers and thats a simple solution. I also like the oil trap nice work. I will be bringing my 1/2 hundredweight back into the shop this year and may well make those changes.
  5. I built mine from a hydraulic reduction box for elevating a naval gun not sure on torque but more than Ric"s as I remember emailing him (na na na na) ! previous incarnations were a lift reduction box and an altered pipe threader (hand twisting) which would easily do 2" square carbon steel hot ,easy work out that is.. they don't have to be that big and motors are not ott if you have enough reduction. but need to have a stiff frame or your machine becomes a pretzel.
  6. I asked Salem Straub...Who does some amazing patternwelding. In modern terms, it was coined by Rodrigo Sfreddo, who has used it extensively in his work. It’s basically a stack of fine layers/thick layers/fine layers, then twisted... as seen in some migration era pattern welding (and perhaps a specific Merovingian sword that Rodrigo saw?) it’s quite striking.
  7. so its definatly possible to melt copper with propane. I have cast a copper Tueiron plate for my smelting furnace with a blown burner (7 or 8 lb of scrap sheet copper)...one thing that may effect a ventury burner is the small gap between the crucible and firnace wall. this will creat a lot of back pressure. I would scale everything down smaller crucible less copper . pop a bit of charcoal in the crucible to help reduce the copper oxide if you get molten copper then add some more charcoal as oxidisation is a problem with copper melting. one thing to keep in mind is that the temp needed to actually get metals liquid is quite a bit above thier theoretical melting temp.
  8. there is absolutly no problem in tempering in oil or low temp salts from a technical POV. there is no reason that oil would over temper a blade at a gvien temperature and one of the reasons to use oil or salts is that they do circulate thus regulating the temperature. I have done over a hundred swords this way. you will need a thermocouple of some kind though. If somthing is going wrong I would look at your overall HT. also check for decarb that can lead to soft outsides on the blade causing a file to bite into the skin and a blade to take a set rather than springing back a little post HT grinding can remedy this. the currents causing warpage in tempering ??? never heard of that but sword blades do move whenever heated or cooled. A word of warning though. hot oil or salts are potentialy dangerous and I have had a couple of tubes of 250C oil boil up out of the tube because of moisture in emulsified oil on a blade and cool oil on a blade going into hot oil....I no longer use this technique for that reason. so be carefull and do your research.
  9. Back to the origional post...what is"Merovingian pattern" is it a modern American thing? I have seen the term come up a few times but cant place it exactly it looks like a variation of stacked multybar swists certainly not historical or Merovingian in any way as far as I can tell. what defines Merovingian pattern in its modern context?
  10. Well I would say go for it! but the truth of the matter is that if it is rite for you you will have no choice.... so there you go. I feel incredibly lucky to have found Job that gives me so much satisfaction...so many people do not get that chance. Is blacksmithing rite for you ...I don't know . but I would recommend trying it. see if you can make it work...or if it works for you. I have had a 25 year long relationship with my craft (23 years as a pro) and its been the making of me...ups and downs for sure and hard work most of the time . but interesting always .. anyhow Im off out to the forge to teach a knifemaking class...have a good day!
  11. welcome to the craft , lots to learn and do. have fun!
  12. If it is a well controlled hammer then yes but it may well not be as efficient as a smaller faster hitting hammer.....I use my 110lb air hammers a lot more than my 225lb one they are better scaled for the work I do.
  13. Thanks for that Tim. It looks like you are running your burner rich (at least mine would be with that choke setting) ... So there is definitely a difference in sound...hard to tell what that means in real world. I will go out and take a reading of my burners to get an idea of what 6 or 7 db really means. I am going to experiment with bigger burners and multiple ones turned down as well and but a 1 1/4 and a 1 1/2 burner (I have a 2"!) . My quest is for a quieter forge, I teach with 4 gas forges running and find that I am starting to lose my voice over a few days! I run my burners at between 14 and 28psi (one and two bar). I do wonder if somthing as simple as a metal box around the burner port would make a big diference...
  14. Tinkertim , is the burner quieter than a standard burner arrangement with the Amal?
