THIS WAS BAD - HAD TO PULL THE RAM

ladies and gentlemen welcome back to the workshop it is fantastic to have you here today's episode is sponsored by nordvpn and you can get started with a two-year plan for 68 off at nordvpn.com forward slash forge and they'll get an extra month for free using code forge at checkout let's jump in we've got a bit of an issue folks matt over here he was running the chambersburg he turned it off and the ram didn't come down see under there that's a ram that should be on the bottom die the ram will not go down it is stuck up there come have a look at this right on the tip of this oil gun there is a big score line a big scratch that means that the most likely culprit of this is the key that holds the die in place slipped out then the ram went up and now the key is jammed against the inside of the cylinder it's really good for the hammer it's really not good for the hammer so if i turn on the power hammer it's doing this moving ever so slightly see it right there the key is sticking out setting the machine in clamp mode but it still does not push the ram down i've tried using the treadle to forge nothing happened if the amount of force that the air is able to put into it to lift it up and down isn't enough to push it down the thing is well and truly very badly stuck i think we need to lift it out of the top and lifting it out of the top is now a big operation because we've got to get the forklift in there we're going to get rid of the gantry and then get the fork lift over top of it oh my goodness this is now a cover project we found the problem thank you will for spotting that one of the bolts that holds the guides in place has come out and it's completely trapped the ram so as you saw the problem isn't that the key is wedged against it the problem is there is a bolt sticking out that bolt holds the guides that help all of this run true and the only way we're gonna be able to fix this is by removing the gantry removing our cylinder cover and lifting the ram almost entirely out let's go get the forklift oh you see that yeah we got a uh storage container let's roll the clip [Music] more space [Applause] [Music] [Applause] [Music] [Applause] [Music] all right we've got the head off which means that now you're looking at the ram but of course you folks are subscribed so you know that's the ram because you've seen our fixing the chambersburg power hammer series and if you haven't you should check it out because that'll help help you learn a little bit more about how these things work well anyway we've got two bolts in the ram what we're gonna do is get a piece of steel strapping we'll then get a sling a round sling in the strapping lift it up with forks again [Applause] [Music] oh there we go that is the problem bolt no the bolt has sheared and that's how it came out that means that we've got to use a screw extractor inside of the bore of this cylinder goodness gracious that's not good we are going to have a problem that is the ceiling you got to change something up because this is not going to get up what i'm going to do is i'm going to put some blocking under this we're going to pull down the sling shorten it up and then we'll lift it [Applause] [Music] all right we've got the ram pull that is 300 pounds of heavy forging goodness check this out though have a look this is where they did a dutchman repair there was a flaw in this from manufacturing from chambersburg this was a war era hammer and you can imagine how it was in the second world war these factories had to produce so much more volume than they were used to producing the stuff probably slipped through the cracks a little bit and this is one of them this ram had a floor in it from the factory and so a repair was done to it i know five or six years ago and there's a dutchman put in that means they cut out the crack area then they put something in and weld it all around it with a spec pre and post heat so they did a you know a spec preheat spec post heat on the world it was all done up to the specifications set out by chambersburg but that's pretty cool i mean it's a huge repair like that's a massive repair and uh yeah i mean it's held up fine over the last last you know six years since that repair was done so that's not the issue we're going to wrap this in cellophane put it on a pallet out there and then have a look at the snapped bolt and see how we can get that out [Music] [Applause] well this is a rambler's power hammer this right here is what that screw is meant to look like and up here you will see that screw is no longer there but you knew that because i've already shown you that screw snapped off so somehow we need to remove the remaining stud from that hole it honestly feels like a practical joke because that screw is about this far up the cylinder we're gonna be getting dirty this again for reference is what fell out and jammed up our power hammer who knows how much of this is still in there those screws are from this assembly right here this can lower down and it can't come out i don't know if i want to do that though you can see where that stuffing box fits into everything if we take it out we're going to have a lot easier access that is for sure see if i can stick my finger in it oh it's stuck it's not it's a good one if i put a pick in there maybe i can feel what's happening like a dentist oh that's weird on the other side there's a hex bolt and then on this side that's very strange oh i don't want to do that but we got to do it we're going to pull this mystery contraption off stuffing box whatever it is it's got bolts the whole way around the underside when we loosen those it's going to want to drop off i think hopefully it doesn't fall and break a foot on the bright side we get to use the forklift again you know every day i go home and i make sure to show mrs steele my forklift certification card because frankly it's the thing i'm most proud of every certified forklift driver knows it's a big deal am i right isaiah you're forklift certified big deal right yeah it's a huge deal huge deal big flex big flex are you forklift certified oh it's so cool that's so cool that is our problem that is one sheared bolt and i think i know the problem it's my most hated thing in the entire world spring washers okay i do know the spring washer has nothing to do with this but anyway this is the snapped bolt or the rest of [Music] it so this beast of an assembly as you saw it sits up here and it houses the ram guides come up this here is a removable piece of material that can be refaced when things get worn and it can be adjusted to provide just exactly what you're after and that's the ram guide there is a slippery material right here it feels like a graphite embedded wear pad or something so this is quite slippery it also gives you some sealing as it conforms to the ram there is also this very chunky rubber seal that is working kind of probably similar to how an o-ring works but it's just a loop of orange rubbery sealing material these guides need to be held on and you can see the damage that's been caused this bolt holds that guide in place it slipped out it jammed up the ram and then was stuck like this so we had to pull that ram out and so it's a beautiful old flathead screw probably made when the machine was made that screw then comes into this nut and interestingly they've tried to lock it so it would never back out by using two center punch marks so once they tightened this they put these center punch marks in that swells out the material from the bolt into the nut locking it in place which is all fine and dandy but this eventually broke i don't exactly know why it would have broken a locked in place over here it really doesn't make sense as to how that broke but just the vibrations over you know 70 plus years almost 80 years of use means that it did break what's interesting is it looks like on this side similar things happened either a bolt broke or they lost it and there's a hex head bolt in there which could be a problem because as you see our original screw has this tapered head to fit inside the countersunk holes that are in there so we might not only need to make this one screw but need to make a second one to replace that repair and replacement okay this is actually really cool whoever did that replacement they put the correct countersink taper on the bottom of the bolt so this bolt is completely fine so i can put this back in no problem we'll tighten it up and that doesn't need any adjustments it has an added benefit of teaching us a potential way that we can make this part way easier if i find the right size of nut and bolt it's as easy as throwing that bolt in the lathe and then simply putting a little taper on the underside of the head and then it's going to fit in there we don't need to make a brand new screw from scratch [Music] my problem our half inch bolt doesn't fit in here and gets stuck 486 thousand 486 thousandths should be the same and it should fit maybe there's a little burr in there we can get didn't work at all let's try this oh there we go didn't take much there's just a few burrs in there there's an undersized drill and the bolt fits the whole way in so that's incredible have a look at this side the bolt head also doesn't stick out past the guide and that is exactly what we want with that bolt fitting next thing is we're going to take the guide plate fully out so that we can fix this little bur that was formed when the snapped bolt got jammed okay the guide is loose check that out there's some cool sealing material to pull out oh it fell goodness this is so cool that's the guide oh look at that and it has a shim in it a 12 thousandths of an inch shim and it has a copper shim that is our guide here's something super cool look at these holes in the casting well these holes go all the way down into this groove that groove runs the whole way around the inside of this casting behind that little ceiling fabric that gasket material that the ram slides upon clearly helping lubricate the back side of it honestly this feels like leather feels like leather but that oil comes around and helps keep this soaked in oil so that it slips really well but also presumably so that it helps seal really well by having all that oil in there but it's amazing all these old machines they really had to plan very carefully how they were going to flow oil to all of the critical parts and so there's holes the whole way around a little oil groove in there it's amazing i love this stuff we're gonna take a pause on serious work for some fun work without anything in here i think it would be really interesting to just get a feel for how much airflow there is when it's working so we're going to turn the machine on without the ram in place [Laughter] that is so cool to see that is so loud oh it's so loud okay so if we're putting this back together we have a little bit of a conundrum which is this when we pulled it out of the machine there was no gasket gasket is used to take up all the inconsistencies in the machined surface and form a seal and so your gasket is a slightly soft material like this that will do that well there was no gasket we're gonna make a gasket real fast [Music] [Music] okay that's in place next up we've got to get the ram back in the power hammer now i've had a whole weekend to forget how difficult this is likely to be so frankly i think it's going to be a doddle easy peasy lemon squeezy [Music] have a look at the orientation of the bottom die in comparison to where the top die is yeah baby yes that's good [Applause] [Music] okay [Music] and look at that we started off two days ago with a perfectly functioning power hammer and here we are with a perfectly functioning well we should try it out first see if it is functioning there we go it runs perfectly so much so that when we turn it off the ram actually falls to the bottom so it's no longer jam what an adventure that was you know despite the fact that that was a two-day interruption i've just had a smile on my face the whole time you know does it get better you get to play with all these 14 000 pounds of cast iron you get to get oily greasy you get to have a whole lot of fun fixing machines is awesome well we've really got to do some more machine fixing i just wish we had something that we can work on that would be both machine restoration and power hammer related well you know i think we're probably gonna find a solution for it so make sure that you subscribe if you haven't so that you can see what we end up finding to restore and fix because maybe it's something a little closer to home maybe there's something in here that we can restore and fix anyway before we finish this video though we should have a little final thank of today's sponsor today's episode has been sponsored by nordvpn they're a virtual private network what that means is they act as an
