  1. Looks like it has been a month since this has seen any action. A couple thoughts. The farther the grip is from the rivet the more universal the tong can be, also the less powerful the grip. Since it appears you may be new at making tongs I would think you might be better off copying simple tongs to build your skills then going into making a new design.
  2. I think maybe Jay copied the tongs from Champion.
  3. I know a guy who makes a lot of knives from old saw blades. They are quick and not a lot of time in fit and finish, however he seems to be making a good living making them. He does not heat treat them, he is just careful not to get them hot while making them. he uses both logging saws and carpentry saws. He told me that the logging saws were more problematic as they were often bent around a pack horse load to get then into the mountains. He also stated that sometimes when cutting out the blade shape they would fracture and that was the end of that blade, I think when he had a problem he moved on rather than waste time on a lost cause, anyhow they work for him.
  4. Thomas's Idea to use a drop while you wait for that really low priced anvil sounds really good.
  5. I think buying tools at really low prices is great when you can but maybe $6 per pound is not that bad, when you are producing nice Damascus I would like to get some I will pay up to $8.00 per pound. Just a random thought, don't delay too much waiting for a tool at 1960 prices. Your time is really what is valuable.
  6. Ben I am rooting for you, if that power hammer works it will change your production in an unbelievable way. Also your elbows might last.
  7. I buy my rivets as much as possible. If I understand your question I think you would be better off to drill a hole the length rivet you want then upset the head that is not enclosed by the hole you could make a heading tool to make your upset domed if that is your desire, however if you are going to the trouble to make your own rivets I would think you should make them more special than the cheap ones you could buy. That heading tool should have a custom design that is yours......if you keep the heading process while the rivet is hot it should drop out after it cools, much like making a hardy tool.
  8. Snuffy I am using my forging hammer for striking tools, I expect my tools to be soft enough that this should not cause a problem. My hammers are mostly either 4140 or truck axles tempered somewhere between straw and light bronze. Just getting to nonmagnetic is not hot enough to be hardening with an air quench on H13. If you go from just finished forging to heat treat with out cooling you likely will end up with a tool too hard on the struck end. My soft hammers are more for helping people with poor hammer skills learn to forge. As far as making a mandrel from H13 for say axe eyes it might make sense if you are planning on lots of axes if you are only going to make half a dozen or something I would not bother. I made quite a few tools from H13 before I ever used a power hammer, the steel is hard forging but the end product holds up well, you should be able to forge it by hand. I would be sure I knew what I wanted my mandrel to look like before I made one from a high alloy steel.
  9. It will need to be hotter than the steel for welding. Just something to keep in mind.
  10. I would recommend you make it to the meeting on the 27th.
  11. My rivet heading tools have the spring on the bottom so they sit well in the vice. I made them with one tool for each size, less options more tools. I really like having the shoulders on my rivet heading tools. I also have tendon tools I have not used them interchangeably.
  12. Is there a planned demonstration? If there is what is the plan, and who will be executing it?
  13. I just saw this I will be praying for you and her and her family.
  14. I have been using H13 for around 30 years. It is my favorite steel for making tools I expect to abuse by getting too hot. The method described by Frank Turley has worked for me for long tools that I do not need to get the whole tool hot in making. (though the struck end may work harden and will need to be dressed from time to time.) For a handled tool like a hammer eye punch you will need to get the back of the tool back down to not too hard or you might be joining some of Gerald's friends down at the ER. Here is how I harden my tools I know this is not as good as it could be but it has worked for me. I use a tempil stick to gauge my heat, after forging my tool I set ti aside, it will be hard all over when cool, I use a gas forge, so you may need to make some adjustments but I take my tool back to harden without anealing, (I know this is not correct, just trying to keep it simple) I put the end I want to harden into the fire, with the back taking a lesser heat, the end I want hard needs to get to 1825F I want the back end to get to nonmagnetic. I will let air cool, I think the optinum temp for hardening quench is 60f in still air I go with whatever the temp is in the shop. We rarely get to 75f here. I expect these tools to get too hot that is why I make them from H13 so I normally do not temper them. (I also know this is not correct, but this steel has been pretty forgiving in this area for me.) after the tool is cool I test with protective gear on to see if I met my goals for hardness and a softer striking end, setting the punch or hot cut to cut a A36 plate and checking to make sure my hammer dented the stuck end. No doubt this can be done better, but it has worked for me, since you already have the steel you might want to try this with a small piece to see if you think it will work for you. The most common problem I see other people have with this steel is after forging their tool they let it air cool and do not know how to get the back end down to soft enough to be safe. At nonmagnetic an air quench does not harden H13 it needs to be more like the 1825F.
  15. When the add is for small quantities and about service, I would expect to see a larger price so might be a really good deal for odd stuff, might be for larger quantities also, we will just have to see, but might be not as good for the regular items.
  16. I really like 4140 it will get brittle if water cooled when to hot. I think Grant made his from a steel that would need care not to harden I have talked to 2 names you would know who were making farrier tongs who both changed from good steel to mild steel as their customers were careless, the new comers will be your problem customers, and it is human nature to blame someone else, we have been doing it since Adam and Eve. If I were making tongs for a regular market I would send a card with them warning the customer and I would make them from nice steel. the tongs you made that I looked at here look very nice, I hope you do well in this. I guess that I should say I think the reason the 2 guys went to mild steel is you do get a bad wrap when you get blamed for the careless and the mild will cost less to use.
  17. you might just have a decarb problem from being up to heat while forging. since it appears you are starting out you might be using more time to finish forging than someone with more experence. I think if I were in your place I would try taking one of the knives I had hardened and file some of the bevel to see if it might be harder after I got past the surface.
  18. I use soft hammers for people who are learning like Thomas said also for hitting my hardened hammers if I need a different set hammer for some reason. I normally just do not heat treat them, normalizing would be better. It should end up harder than brass.
  19. I have used fire extinguishers 4 times, glad I had them for each time. the first time a friend and I were shoeing in a community away from home one of the locals comes running in "the house down the road is on fire," we were able to slow the fire down until the vol. fire dept.was able to get there. We were not able to actually access the source so the fire would flare back up after we knocked it down. The next time was a car wreck really could not get the hood open so the car eventually burned but I was able to salvage some of the items in the car for the owner. The next one was a truck parked next to a fuel tanker I was driving by very late one night and noticed there was fire dropping down from the engine compartment onto the ground, called 911 they had me wait until the police showed up then he and I went over the fence and were able to put the fire out, not sure I would do that again as I learned they drain those trucks at night so seems like a bomb to me. The last one was right in front of our house, we were in the yard and heard a big boom ran out to see a head on had taken place with the one car on fire 2 people trapped in it, ran back to the house got the extinguisher, got it out, ran back for another in case it flared back up but it stayed out. When the fire dept. got here they worked for a couple hours getting the one girl out of the car the driver was killed by the impact. Only the fuel co. ever replaced the extinguisher, I think they only did it because I was shoeing for the wife of one of their drivers and i mentioned to her that I thought they should.
  20. Latticino the 1045 that quench cracked did it happen right at the time of the quench or later if not right at the quench how long after? could you have tempered before the crack? I guess I am hijacking, really curious I have had 4140 crack and some that was fine after water quenches. MillwakeeJon very nice hammers for the first 3.
  21. I guess you are covering the wooden sheath with leather to make your completed sheath. I am unaware of this method, but it seems safer than just leather. I should try a few birch bark handles. They look pretty nice. Thanks for sharing.
  22. If the rivet that you are going to upset into a head is about 1 1/2- 2 times longer than the diameter that will work out ok. most times. Too short not enough head weak to long trouble with bending rather than upsetting.
  23. I am a big fan of doing the same project many repeations. The hooks described by Vaughn is a good illistration and start, this is the kind of work that would be expected of an apprentice. I guess that really does not answer the question of how long a session should last, but if they are really short you are not going to really get much done. A lot depends on how you are set up is your shop constantly set for work or do you need to roll out all the equipment from storage to start......I would think you should plan to have an hour if you are trying to get anything of value done.
