Part Two: Excavator boom repair

so [Music] [Music] [Music] uh [Music] problem [Music] [Music] so [Music] [Music] [Music] so hmm so so [Music] so [Music] [Music] all right so none of this uh plate that i cut off is really important being this how i'm going to replace this whole bottom piece but i figured if i could cut it off really nice or close to flush there's less grinding for when i install this piece here now these cuts aren't the straightest in the world no but they'll work right especially if i have a a root opening or to say a backer plate so i'll straighten out this little curve here and um put the backer plate put that piece there and that'll be stitched up for now and so at that point i'll be able to focus on cutting the bottom piece off i think i'm going to go about four inches or so past this weld joint before i or so i can cut this other piece and then go straight across same thing over here and that way there's not too much weld uh joints in one spot offset it about that far unfortunately this top one is offset by over a foot which is good and so at least the bottom will have the same not so much stress is built up in just one area all right it's looking good [Music] as you can tell in the cut here this half the tip was dirty i stopped the cut there something got it in the tip and it got dirty right in there so now we got to bevel this side and the opposite side [Music] [Laughter] three nothing a grinder can't fix [Music] close enough that's a 37.8 degree angle right there i calculated it i'm kidding by the way it's good cool heck of a gap in there but i'm going to be putting back in place so it'll be a really good uh got about that looks to be about maybe 5 16 or more uh which is fine i guess it's enough well little hole all right let me get those uh back in place i guess that's why they call it stick welding sticks [Music] okay so while the gap is a little inconsistent it's not that big of a deal uh i can grind that as i'm straightening that out and be fine same thing here that looks good that's about as close as i'm sorry as far that way as i could do it that's kind of a pain and this one was a little bit better off so about 5 16 yeah so it is what it is and it will work here what i'm going to do is i'm going to be torching straight down and i will be cutting into the bottom plate here and i will i will angle the torch in just a little bit so that i can see that i have to see the separation line between this plate and that plate and then i will make a cut towards the center i measured from the bore edge to a specified mark over there same on the opposite side i checked these to the center borders where the lift cylinders are and they're very square so i can trust that that's close enough i mean even at that it's going to have a backing plate so you can adjust a little bit here and there so that's pretty close so i'll make that cut kind of angle that torch cut in so i could see it from the inside and then i'll make the cut across to the other side [Music] so [Music] you see here look real closely you can see the separation line kind of hold the camera and get my pliers at the same time [Music] right in there there's a separation line which would be nice very similar to that separation line so now i would run the torch underneath make it to the inside mark a line cut across [Music] so [Music] all right so now i'm at the point of um cutting this piece out right here right there and one of the things i like to consider is the grain structure of the plate and i really don't know if it makes a difference but you know on when you try and bend a flat bar in one direction that works great but on the other direction it tends to crack or tear so i have similar thoughts on that with plate material so as i laid this out i put arrows here to show the direction of what i think the grain is running so hopefully it'll be a little bit stronger that way than if they were running this way so that's just a little tidbit of information there not sure how scientific it is but that's just what runs for my mind because i think a flat bar and a very similar process with plate all right time to cut this thing [Music] okay so this plate is going on okay got a little bit of a gap there which is good right here looks pretty good got a little bit of a gap get right in there no problem squeeze that down had more gap on this side looks like this plate was a little bit warped and looking at that plate over there you can tell it is a little bit bowed it was boiled from the beginning but either way no biggie you can't just squeeze that down a little bit make it touch it's got about a a strong eight but other than that it's okay looking good uh here with these angles or diagonals right here i like to cut those last that way it matches up perfectly there's no mess around or fighting trying to shove it here and there and try to get exactly right so just come up here four or five inches i forget exactly what it is maybe about three inches and then continue that line this way and so whatever this line uh says here at this point run a straight edge along it and just continue that they're swinging and cut that cut that in look factory factory as derek says um westbrook garage by the way anyway so things are looking good i will go ahead and tack this in place and i can mention i think i mentioned before i usually like doing the bottom first but in this case i won't be able to so i'll tackle this i might weld it up but i actually need to start on this piece now and that'll actually probably be a different video so it'll be a combined you'll see this one not completed as i'm working on that one because once i get that done then i can break free the little tacks that are holding it in place here and then roll this on its side to weld all the things from the underneath side so i like to do it overhead and i'd like to show off doing it overhead right all processes are all positions right but when there's something important like this if you can turn it around it's best to turn it around so i will uh okay looking good a couple tech techs and keep moving [Music] as i mentioned in the last video that i'd been finishing or working on this section here before i completed the the tail end of it so that i could roll this whole unit as one at one time you know if i need to turn it around and finish out welding it so here i am starting on this guy this guy's had some pretty serious cracks right in here and pretty nasty wells i don't know what they were trying to do but i mean hey they're trying to keep it going so it is what it is uh right in this area there's a baffle an internal baffle that's in there i'm not sure you can see it but there's some distortion right in here right in here that you can see where the welds are on the inside of the baffle and so my thoughts are to cut this section out and restart or remake the whole new side plate customer provided material so that'll be fine uh this up here will have a little radius to it i should be able to bend it on my little press break just little little steps at a time either that or just clamp it down really good i'm sorry about that plane going by oh it's way up there and uh so that'll be next i'll be cutting these sides uh off this up this side here yeah it looks like they didn't even try to grind into it or nothing um and from the looks of it here this surface looks like it bulged out like it's not flat uh it's not uh right okay so i guess we'll get started and see how much we can tear apart so i just burned the paint off in this area where i'm going to be cutting it's kind of a big patch and one of the things that i mentioned earlier was that the you can feel from the weld on the inside that this is where the interior baffle is and so i'm going to make just a cut right along these areas nothing nothing precise nothing critical because i'm going to make a a patch or a pattern to lay over it again and i'll mark the lines but at least i'll be able to or mark new lines actually and then at least i'll be able to get an idea of what's in there what's going on and i've got some poster board i'll lay the poster board up top hammer against this edge you know uh like a hammer fit and it'll cut that poster board same thing along the bottom and then i'll be able to push it up against it just so long as it overlaps the cut area and i can just mark a new line and then trim it up a little bit more precisely that way so now i am going to cut this and it's not gonna be pretty cause you know there's an awful lot of weld in this area here and it's probably gonna have a lot of cracks a lot of stops and starts because you know torches don't like uh cracked areas and it's hard to keep going and then getting around this this baffle piece so it won't it most likely won't fall out so i'll probably have to cut this section out then this section out and then trim off the the excess weld and things off of that after i do the top so lots to do still again i still haven't finished this but it's getting there and you know nothing to about to do it so here we go [Music] so [Music] look what i found from the factory you can't really see it uh maybe so well but they put in a small piece because this plate right here was short almost like if they did this in there so that caused this stress crack along this stress riser right there in that corner and cracked all the way up and it comes through on this side that is crazy yeah so stress riser right there from that corner straight up cause it to crack up here incredible as i mentioned before uh rain's coming this piece oh there it goes look at that this piece was broken in there all right okay i gotta go range coming so uh anyway i'll cut the other side later i put a damper on thing oh man my little rain gutter didn't work well all right well i guess we're going to pause on that all right see you guys after a while
