  1. Update on this hammer.

     

    Old Motor fell to dead short last year and was replaced with a modern 7.5 hp in the same location.

     

    During our hammer-in this year we were forging out a large billet of pattern welded material and the anvil worked loose and laid into proper position!

     

    The hammer honesty gets very little use but it is nice to now have it setup correctly.

  2. 4130 will harden to 48 Rc when quenched from critical temperature (around 1500f , right when it becomes non-magnetic)

     

    It will harden considerably.  More importantly it will change in toughness and the ability to hold form/shape. 

     

    Normally 4130 aircraft materials are fully annealed at 32 Rc when purchaced with somewhere around 35,000 psi Yield.  Heat treated they should show around 180,000 PSI Yield.

     

    Stress relieveing is more important then tempering as there is no real need to get below 48 Rc for most applications.  400 deg F for 2 hours post heat treating should be fine. 

     

    We process around 10,000 lbs of 4130 AV grade stock each year in thicknesses from 20 ga to 1/4 inch.

     

    Many people will tell you it is case harden only and cannot be through hardened and they are half right.  It will only harden about 1/8" on each side of the material thickness, so stock up to 1/4 inch will fully harden.

     

    You must get it up to a non magnetic state to harden it. 

  3. I recieved a phone call last night, the machine shop has finally completed the front end work on this hammer.

     

    New cushion plug and bushing, truing of the tup, new guide plates(iron this time!) to match the new bore size with bronze pins, weld up and recutting of the dovetail, completely repaired guide ring with steel mounting flange interferance fit and bolted to the existing ring.

     

    I expect to be picking up the parts on wednesday.

  4. So with the motor mechanics rebuilt and cleaned this beast is finally alive.

    We ran it 2 days during the hammer In with no complications.

    The anvil is still stuck in position with shims on the dies to get then close to flat.

    After the event we tweeked it more and I am actually considering shortening the stroke as it is now hitting very hard.

    Keeping the break tuned in is a bit fiddly only because there was a fair amount of surface rust on the break surface. As it wears in I have had to adjust a fair amount.

    I am looking to getting some time in on it this weekend.

  5. Getting closer!

    The guide ring has been rebuilt and has a new solid steel ring pressed and pinned in place

    The ram has been trued up and has a new cushion plug installed. The dovetails have also been welded up and recut like new.

    The cushion tower has the new cushion bushing installed

    We are only needing new guide plates to replace the tool steel ones and a new ring on the cushion tower

    Hopefully more updates in the next couple of weeks.

  6. On the 4B Nazel Sam is refering to, Yoder removed the dies, the oiler AND THE CUSHION PLUG. The guides were brand new and made from hardened tool steel. They had badly damaged the ram that is now thankfully rebuilt. The guide ring was overheated during a bad repair making the casting extremely brittle. That ring has been rebuilt using a steel ring that will be at least as strong as new.

    This hammer has now had considerable renovation and is close to going together.

    It was painted nice and pretty and sold for $5500 from Yoder on ebay.

    Buyer beware!!!

  7. Sorry for such late notice everyone!

    Please consider joining us for the 2012 Fire and Brimstone Hammer-In and Smelt on March 31st.and April 1st. 2012 in Historic Marriottsville, Maryland

    The event will be at our forge (Baltimore Knife and Sword Co.) and the Church/Studio next door (Fire and Brimstone Studio).
    Having sold the wood lathe you saw last year (Oliver M159) we have installed a 27" Pryibil Spinning lathe. Bigger is better right!?!

    Jesus is hoping to reduce a large bloom on the big Nazel this year and we are chatting about what kind of ore smelt we will be doing.

    The beaudry is recieving a new motor this week to make it more reliable.

    Something you would like to see? Post it here and we will add everything we can.
    We will be limiting attendance to 60. Registration will be $75 for the entire weekend to offset our costs. Vendors and tailgating is encouraged at no additional fee and will have separate parking, trailers allowed.

    Please let us know if you plan to bring anything that will need forklifting and we will have one available.

    Please visit our site http://www.fireandbrimstone.com We will update the event section over this next week. Feel free to use the registration sheet as is incase you get there before us.

    The site will include accommodations, Schedule, and Artists/Demonstrators. We are still rebuilding the site but it is live now and registration is open. I will be talking to the local hotel to see if we can get group rates. Breakfast and lunch are provided, grills are open for anything you wish to bring or share! Camping is encouraged but weather in Maryland is always suspect! The later dates should help us out quite a bit. The first year we had snow, 2nd year it was down right warm and sunny, 3rd well we had a little water, 4th Having a roof makes all the difference!!.... There are bathrooms(spot-a-pots) but no showers.
    We will be updating the site often as we confirm additions to the event.

    Doug Seward and his BBQ have confirmed!!!

  8. The hammers you are buying are certain worth the money he is asking.

    That being said if your worried about the added expence of a phase converter you better start talking to guys with 2B's who know what it costs to rebuild one.

    The current seller has described the running hammmer as in need of a complete rebuild. Get serious about what that means as it is very easy to double the cost of the hammer to get it running. Very easy...

    The second hammer has a broken frame and dont expect any of the parts to be plug and play between the machines.
