  1. Heat Treating a Frizzen

    Your idea to use 1095 will work. Some guys take and forge weld a piece of high carbon onto wrought for the frizzen. I would check out the american longrifle forums as I know there are a few topics on this subject. Cranky much Steve?
  2. Hello From Delaware

    Hey Two Ravens, Good to see another Delawarian on here, I am in Townsend "below the canal". We have a pretty awesome community in our area. I don't have a lot of time to post right now (3 month old little one myself) but I'll try to PM some info your way tomorrow about local people, groups, events, places to find materials ect.. if you're interested. -Morgan
  3. Tuyere size question

    lol steve. Not everyone is going to run MC on their forge. McCartney, a place to start would be to figure out what CFM your current blower is, which would give you a idea on how much air you need.
  4. cello bending iron

    How about we ask the OP to clarify, since he has only responded once to the original post. Do you have any previous casting experience? What exactly is the refractory being used ie - the brand name. Standard concrete mixes trap moisture inside and when heated evaporate the moisture which then cannot escape, causing it to spall or explode. If you post your location in your profile someone might be able to give you some local sources or places to get help or instruction on a project like this. Casting seems to be a taboo subject on IFI because the danger is real and high, to life and property. Searching and reading the past casting threads is helpful. Also there are casting specific forums on the web that might give you additional knowledge on the subject.
  5. Navy Hammer sell off

    I have seen Matt Harris's Niles Bement-Pond 750 run, and it has been converted to air. He uses 1,000 gallon propane tanks for the cushion tank and a large engine driven compressor, like 750 CFM. He acquired a large 3 phase rotary screw compressor in the 40 HP range and plans to convert over to it. These hammers work hard, and it comes down to how many points of maintenance and failure you want to deal with. While a boiler is great, and can double for steaming crabs and clams, it's a whole other bag of worms. If your boiler goes down in the middle of the job you've got issues. If your compressor goes out you call a equipment rental company and have them drop one off.
  6. Having stuff inside helps a ton, but I am a strong proponent of anything that makes you look harder to burgle. Cameras, exterior lighting, and a real alarm system where someone calls the police. You want to try to convince them not to do it in the first place. A lot of people forget in the trades that once someone does get into your shop, all the tools are there to defeat whatever low tech "security" you have in place. How many folks have a grinder, cutting torch, or bolt cutters in plain sight in their shop? At that point, if an alarm company isn't calling the cops, or you are not recording them, they have all the time in the world. Also, make sure there are no "tools" easily accessible outside to help a would-be burglar. Whenever you talk about theft, I think of the flip side which is insurance. With the rise of the home hobby blacksmith and the parallel increase in anvil and tool value, I wonder how many home smiths have spoken with their homeowners insurance people about a rider to cover the theft of those items. Most of the time I see posts to the contrary about people afraid to call them in the case they're told a forge is a no-go under their policy.
  7. Maximum stroke length

    1. The cylinder doesn't have to fully retract each time you want to stop applying power. It's really dependent on how you plumb the system. 2. The simplest way to plumb it so it won't have to retract all the way is to use a regular hydraulic valve. You pull the lever, it comes down (or up if the cylinders on the bottom), squish, and then pull the lever till it's backed off enough to move the part and then repeat. There are other ways with limit switches ect.. to set the retraction height as well but that gets into more money. 3. Having a longer cylinder is a advantage over many presses, not a disadvantage. You can keep more of the rod inside the cylinder which makes the rod less likely to bend or flex during side loading, which can occur depending on your press design or where on the dies you are pressing. I think my cylinders are 24" long, and I plan on making my "press zone" about half of that, so half of the rod will always remain in the cylinder. 4. Consider that you want your work at a comfortable height, and design the press to accommodate it. Check out Randy McDaniels Press on youtube, and if you can get your hands on his book it goes over a lot of the basics. Also, look at a bunch of presses and find a good interchangeable die system you can fabricate.
  8. About to start my smiting adventure

    Since I am in DE, I've never been to one, but hear it's a good time. The shop is fully equipped. Bring what ever tools you prefer and your project, but there are tongs and hammers and tools there to use. I think there's 5? coal forges in there. Each station has a anvil and a post vise. If it's something your interested in go on their website and reach out to the President, Ted McNett and he can point you in the right direction. The cost of dues is paltry compared to the experience earned and cool people you will meet. They usually have blacksmith coal for sale at meetings but check with Ted on that.
  9. About to start my smiting adventure

    Blacksmith Guild of Central MD. There based out of the Carrol County Farm Museum. I am a member, and their Blacksmith Days in May is a excellent event. Even if you prefer the school of hard knocks, just having some people to call or come over when you get in a jam helps. The tailgating at events is a plus too. They also have open forge nights. For small batch charcoal the easiest is just get a fire pit near your forge and build a fire. When you have a nice bed of coals transfer it to the forge and add more wood to the fire.

    Hey Beaumont, welcome to the forums. There are a bunch of good blacksmithing groups in MD. Where in MD are you?
  11. How do I keep a fuller straight?

    I don't know of anywhere to buy one off hand. Most are in-house made and a lot of the ones I have seen use a carbide tipped lathe bit for the cutter, profiled to what kind of fuller your looking for.
  12. How do I keep a fuller straight?

    A lot of folks use a tool like that to set the initial fuller and scrape the fuller cold with a fixture to the final dimensions. Google fuller scraper and you should find some pictures.
  13. Tooling up for twists

    There are factory machines out there that do twists and ones people have made. Most of them are on the large side for doing architectural and pattern welded work. You said pendants so I would think your working on the smaller side. I would look at pictures of these machines and see if you couldn't make something similar but on a smaller scale. Most of the ones I have seen have a chuck and a motor to drive one side and the other side just has to hold the stock so there are many different types of solutions. The "dead" side is on a sliding track for different lengths of stock.
  14. The downside is it doesn't use the standard thermocouple probe jack with the two flat terminals, so if you got a good thermocouple in the future you would have to rewire it. I bought a K type dual illuminated readout from amazon that takes two standard thermocouple connectors for 20$ off amazon a while back, and compared it to my Omega Engineering readout and it was within tolerance. Now the Omega is back in my toolbox where the likelihood of it being melted is low lol.
  15. I love my 33. It hits hard, and the new heavy series hammers have a longer stroke for better use of tooling. I haven't had any real issues with it. When I first got it the tup wasn't retracting all the way so I switched to ISO 32 oil (10wt) and haven't had a issue since. James is also top notch for support if you need it.
