  1. Pics are as follow, first is the rear guides at BDC approx .085 play. Next is front guides approx .030 play. Final is rear guides at TDC .050 play. Its hard to see but on the left side of the tup it is visibly worn. Front looks good. Im not sure shimming less would help in the back unless I shimed in between the frame and the guide as well to angle it in. Let me know what yoy think. 

  2. Start with Pounding Out The Profits and after that Google patent search is your friend.  

    Detail photos of worn parts would help with diagnosis.  Ram guides often have shims or smaller contact area on the face plate (the removable part on the front of the hammer, not part of the main frame casting) that can be skimmed to tighten up the fit.  I wasn't suggesting replacing the tup, just machining a few or 10 thousandths off the slides.  YMMV

    Judson, removing existing material is not a option im in favor of. There are shims between the front and back guides on the frame. Due to how the guide is mounted to the frame i fear I have taken all the slack out I can with the shims. I know with the front shims I shimed until it stopped binding. The back are the loosest ones at I'm going tk approximate at .075 with my measurements. I was under the impression with the tensioner on the shackles of the spring is how I tightened the belt. I may have to re wrap with the eyebolt nuts as loose as they go but unless I have concrete instructions that say compress the leafs im warry about doing so. Im not sure if the patent number is on the machine. I will try to post a pic of the badge and see whay yall think. Thanks for all the advice so far!!

  4. Slides need to be straight and parallel to each other every way possible for best performance.  That means front to back, side to side, guides AND ram.  Sliding fits may be found in the Machinery Handbook,  mechanical power hammers are probably ok if anywhere near the loose end of the engineering spectrum.  Crappy guides can be used (and often are) for short term gain but the looser and wackier the more diamond shaped your forging will be and the faster the hammer will wear out for good. 

    Tups are easier to machine than frames.

    As to the strap, they had those clamps on there for a reason.  Put them back and find a way to keep them from scrubbing.  Try higher tension on the strap.  WAG here.

     

     

    I am afraid to have the tup repaired since it is cast. It would have to be built up with weldment and machined back down. On the left side of the rear slide on the tup it is visibly worn down. How much play am I allowed to have? 

  5. Black frog, I moved the clamps out to stop them from rubbing against the ram. It was causing a lot of ware on the head. Also do you know how much play I'm allow in the ram guides? Either I'm holding my steel wrong or my ram is floping enough to cause my steel to diamond. I've eliminated as much play as possible,  my only other option is to pull the ram and have the slides built back up and machined down. Unless yall have another idea. 

  6. Well I finally got the scranton up and running and boy does she run good. I'm still in the tuning phase and had a couple questions for yall. This is the first mechanical hammer I have ran and am wondering if kinetic feed back in the treadle is normal? Another thing I'm running into is my belt that runs threw the ram is sliding to the right. Now this wouldn't be a problem but for the fact my belt clamp is lightly smacking the side of the guide. Any tips on fixing that? 

    Here is a pic that kinda shows the belt running to the right. Otherwise shes a beauty and I love her. Thanks all.

  7. Andrew, the crack is in the back of the hammer near the hole for the top u bolt that holds the hammer. Its a vertical crack that extends towards the hole at about a 45 degree angle towards the hole. I wire wheeled all around it and it does not seem to reach into the hole. Aprox 2 in in length. I plan on going nuts with a wire wheel anywhere there is a stress point. Might just do the whole dang thing to make sure. Ive already contacted a local welder who has experience in welding cast iron to come look at it. If it was cast steel I would be set because I weld cast steel on a daily basis. Unfortunately i have no cast iron welding experience. I will keep you all posted and will try to post pics. 

  8. Hey all. Here's the scranton and co hammer I got. It was actually a lot easier to move than I had thought. As you can see she is standing in the shop and is in need of a foundation. I think I've got a good handled on that. However I have a few questions on making sure she is up and running right. 

    First I'd really like to know how much play I'm allowed to have in the shaft bearings and the head guides. The bearing caps seem to be able to be tightened to take out play. Same with the head guide mounts. 

    What oil should I use for the bearings and what grease should be used on the head guides. The electric motor also has oil ports, is there a special oil for the motor? 

    The hammer head looks like its twisted and i know it needs new belts but am not sure how to fix those. There is also a weld on ends of the springs. The appear to be broke so I'm not sure as to there intent.  

    There is 4 holes in the frame for the electric motor to mount. One is striped and really close to the frame and it concerns me. If it's fine where its at, can I helicoil the hole?

    If there are any other things you can tell me or give me advice on, I'm all ears.

  9. Hi all, I'm going to be getting a Scranton and co power hammer this weekend and am wondering how I'm going to move it. I should be good with the pick up, we plan on laying it down on a trailer. I know it's not the best plan but really the only option. When I get it home getting in the shop is a problem. The guy says its 800 lbs, I'm sketchy on that. I have a couple pallets i could set it on and possibly get skid steer to get inside laying down (as the hammers 8ft and my door is 7ft) standing it up will be an issue. Could I, with out messing anything up, basically dissasemble it and put it in that way? Any advice would be great as I don't have long to figure this out! Thank yall

  10. Hi all, just got in my Mizzou castable refractory, and am waiting on my ITC100. I have a couple questions on applying the stuff since ive  read so many different ways to do it. What im working with is a 12 dia × 18 long forge that im going to wrap with 2 layers of 2 in kaowool, bringing my interior down to roughly 4" diameter. Heres my ?

    I have 20lbs how much do I need to mix up?

    Should i let it dry a day or two before pouring the floor? 

    I've been told mix it to yogart consistentcy and paste it in the forge,  good idea? 

    Should I fire the Mizzou before applying ITC? 

    Also I've had some issues with my old lining falling down after getting really hot! How do I avoid this with the expensive stuff!

  11. What about using gas hose line? We have 1/4 high pressure hose at work and all the fittings. Under 100 psi they don't leak and unless they get red hot steel on em they don't melt and even then only a little. A gent I work with told me I wont have much play in the way of moving the tube around. I  want to go tubing style but I don't have a fixed point for the end of the fittings so the changing of tanks/tuning of burners will make them move a lot. 

  12. Hey all, working on a new burner set up for my forge and am having some issues with the propane plumbing. I used 1/4 inch copper tube and compression fittings to hook it all together to the valve leading to the gas hose. Its all leaking like a sive. What options do I have as to hooking up two burners to the same line? Am I using the wrong fittings? Is there a manifold I can buy that will allow me to have a little play in the placement?  Thanks in advance.

  13. I'm sorry all, I'm trying hard to grasp the concept of natural Draft but it is a challenge for me to try to learn technical knowledge on the Internet. I think I might do what you say Jim and add a cover of sorts to help out but I'm going to need something permanent in the future. The opening of the hood it probably 9x9. I'll try to get a pic up.

  14. Hi all, I need some advice, I get to much smoke in my shop and need a solution. I have a photo of my idea, it consists of a 2 ft shop fan with a funnel and piping of some sort, blowing air at an upwards angle hopefully adding suction to the chimney. Let me know what you all think.

Thank you all for the advice and your time. Keep calm and hammer on yall.
