[@Mongo63a]

We had a similar rock that kept destroying lawn mower blades in our side yard back in the 70s. Father decided one weekend to get rid of it. Turned out it was 5 ft in diameter. We reduced that sucker to rubble with a manual star drill and a sledge hammer (free kid labor). As soon as you pointed to the top of that one I knew the story.

I love your videos Bro. I'm 70 yrs now and I grew up on a farm. We fixed our equipment in the field where ever they broke down. We had only the tools on board. You would LAUGH at some of the things we used. But we made it work !! HoooAH ?

[@delasantos]

Mate, absolutely amazing effort fixing the slop in that bucket. Even though we all wish we had a workshop like Cutting Edge Engineering, you did an amazing job with your mill and lathe. Seeing the bit drop in both times was chef kiss perfect, and then working with the imperfection to get the job done ... impressive! Subscribed and liked, please make another video on how you fix up the track. All the best from land down under.

Was just thinking about how this is a job for CEE …if they weren’t on different continents haha

[@ToreDL87]

@@buildingsalvage Continents, and price range. I love CEE (and Homie), as do we all, as we rightly should. But to CEE, KZbin is secondary, they're a business, remember the workshop he has that we wish FarmCraft had? CEE caters to a very very boutique and heavily government subsidized market + there's a material shortage (so costs even more). The time CEE would have spent lineboring, welding, lineboring, freeze-fit, on the pin ears for this Yanmar Stick, for the money it is that you THINK they should be doing it for, he could have spent the same time and effort doing the same exact thing for 5-10 times more because that's how much their customers are willing to pay. CEE and FarmCraft could have practically been neighbors and it wouldn't have made any difference unless they were friends doing favors to one another. Not to put CEE or FarmCraft (who did an excellent repair btw) in negative light or anything of course, and if CEE wants to correct me on anything that I've said, they're free to do just that.

[@billmiller4800]

Suggestion for that rock: use your drill to drill a couple of vertical holes in it that will fill with rain water. If your area ever freezes in the winter (or with some external help, LN/propane/dry ice) the freezing will eventually break the top of the rock.

[@12345NoNamesLeft]

They have a cement mortar that does that. It expands when it cures, sold for rock breaking.

[@74KU]

@@12345NoNamesLeft Its called Expando, or that is one brand anyhow.

[@bobbygetsbanned6049]

Go Egyptian style, hammer in a wood wedge then get it wet, it will break the rock when it expands. Or use the fancy expando stuff or whatever those guys are talking about.

[@ronm3245]

The rock will gradually work its way up so generations of people will have to deal with it a few inches at a time. Or someone can deal with it all at once.

You can weld cups around your grease fittings that are exposed to prevent them from breaking off and getting damaged just a tip.

does not matter if your country sink then grease fitting you looking at build up with dirt in the holes they are not a right or wrong way to do it how any time i had to change out the grease fitting when the damaged by Debra too

​@@jenniferwhite6089 huh?

[@mikeprimm4077]

That's actually a good idea, I did that on my mini, the grease fittings on the end of the stick by the dog bone kept breaking off. Haven't had to replace one since

[@mikejd35d23]

Just as an important note, that quick attach housing is loose because the pin is supposed to be statinary. It is supposed to turn with the pin. There are no bushings in there for a reason. Your pin is supposed to have a hole drilled in it to hold a split pin. That is why one of the bosses had a hole in the casting. If you leave it like that it will wear out again, grease or not. The only part of the pin supposed to move is the bushings in the stick and the thumb.

[@avid6186]

The first side he bored on the mill had a hole which should have had a pin though it and a matching hole (missing?) in the main pin to stop it rotating. The rear pin had an "ear" and a bolt holding the pin in and stopping it turning which will be why it wasn't as worn.

[@robandnell4305]

Most excavator have a pad that is big enough to fit your heal on as well as your toe. Fun watch

[@ToddKing]

At 8:25 it looks like you can see the hole in the pin. Not sure how the hole in the casting and matching hole in the pin didn't set off a light bulb. But I've missed obvious stuff too.

[@heklin]

nice work, just for future reference, you can use your lathe as an impromptu line bore, as long as your bed travel is at least double the width of the part, you need to make a solid bar that you can run between centers with cutters added through the bar in 1 or more locations. takes a bit to set up but once used to it you will get perfect bore alignment every time.

[@albert1991]

In my opinion, the quick coupler hole was worn becouse an incorrect fitting. The pin should stay stationary with the coupler, you can see that from the fact that the coupler had holes for insert a bolt to stop the rotation of the pin. When they installed the finger has removed that feature and now the pin stay stationary with the stick arm and wear the bore. Recentrly, Dirt perfect has installed a new thumb to his new hyundai and he welded a piece to the coupler and the pin has ear to engage in it to avoid that problem. Your video are ansome, truly they are! Better and better!

[@jeffmeyers3837]

Curtis is a pretty good amateur machinist, amazing should be reserved for those in the trade. If he was amazing he would've used a dial indicator on a shaft in the chuck to index the lower bore before boring out the second one at the top, then they would have been concentric. I spotted that mistake before he made it. But as a tech guy for 25 years, I sometimes miss my machining days.

[@davidrice4172]

You are amazing. A jack of all trades. Love watching you work.

[@slipsonic809]

You need to get yourself a set of feather and wedges. You just drill a line of holes a few inches apart, insert the wedges, then hit them in sequence. The rock will crack off pretty much in line with your holes. You could have dug a foot or so down and popped the top right off that rock.

If you only knew how many times I was able to say, "That's what she said." during this video. Haha! Hey great video you are a great machinist. Here's a little tip for you next time you are trying to fit a sleeve into a collar. Putting the sleeve into the freezer that was fine, that's what you should do. However when heating the collar, go to the area on the edge where the collar is thinnest and just heat the metal there. Maybe like an inch wide section with a finer Torch flame. It will actually open the hole more as it is only expanding the metal at that section which pushes outward, almost like putting a hydraulic jack in the opening of a "C". When you heat all the metal all the way around it expands inward also.

Once you bore your first hole on mill. Make a light fitting pin on lathe, with a wide thick flange to clamp to your mill.(maybe drill holes in flange for cap screws into tee slots) Dial indicator pin, to get it inline with mill spindle/quill. Note table position exactly. Move table to side, and mount bored hole over clamped pin and clamp down. Return table to exact same position, and bores will be in line. You have a great channel.

On the Fourth of July, drill a 3/4 inch hole in the top of that rock as deep as you can. Fill it with black powder, put a long fuse in it, pile on a couple of large sand bags and light it at dusk.

[@daverose4789]

great work done there and a fantastic improvement in the bucket. One method you could have used to get the alignment of the second hole is to use a dti to 'clock' the already machined lower hole. You'd need to mount a long shaft say 3/4" diameter in the mill spindle and attach a dti to the bottom end of it just above the lower hole. Adjust the table position to zero the dti and the mill spindle is exactly on the lower hole. Refit the boring head in the spindle again and the second hole will be bang on center to the first. Keep up the good work . Looking forward to the next installment.

[@terencem9962]

That's exactly what i was thinking about in me head! KZbin is so great to see other machinists work and then to see comments from machinists about said work. Much can be learned :)

[@DamLins45594]

I was thinking the same thing as I watched this. Not sure if he has a DRO on his mill, which may have helped him get close enough to use the DTI to zero in on the bottom hole, assuring alignment of the yet to be bored upper one.

[@nathancook5354]

Any excavator I've run that was new enough for foot pedals has them come far enough back so you can step down on them to reverse. I'd guess that the actual pedals are missing and what you have there is just the bracket that the rubber or plastic was supposed to attach to. Still better than my old CAT E70 that you just have to angle your foot against the lever though. Well done on the bushings there, that would have been an expensive replacement or even repair from a machine shop.

[@kd2eat]

I was thinking something similar. Does something fit over those foot petals that allows you to place your entire foot down and tilt forward and back.

[@Sugarkryptonite]

I also have a Yanmar, albeit smaller, a Vio17, and it is the same thing. The pedals are absolutely garbage and the angles are not ergonomic at all. I even had to cut and modify the armrests because they were the same way. I've seen a bunch of them and they're all the same. Don't think anything is missing here.

I thought the .002 interference fit was too much but was impressed with how you did it. After you bored the first hole I would have made a fixture with just a round plug screwed it down through the center of it to the mill bed and then indicated my spindle to it. Then used that to locate the center for the other bushing hole. Also I would not have drilled the zerk fitting holes where you did because of weaking that part. I would have drilled the pin and put the zerk fitting in the end and had a hole come out into the middle of each bushing for grease.

I've very much enjoyed your channel since I discovered it a few months ago. Here are a couple of tips that might make your life easier Welding: Though I'm a trained welder, I've always had a problem of staying oriented after dropping the hood before striking the arc. I tried the electronic hood but the sudden darkness also disoriented. I solved the problem by simply illuminating the work bright enough that I could see it through the filter. I used to use a 1500 watt metal-halide lamp in a parabolic reflector on a stand I made. I have replaced it with a 1500 MH-equivalent LED COB light. It draws 120 actual watts but it produces at least as much and probably more light but without the heat of the MH lamp. Rock Breaking. In the 80s I had a home with a dump truck sized boulder touching the house right where I wanted to build another garage stall. I consulted the local farmer's co-op and they sold me a product named Cold Dynamite. It relies on the large expansion of the hydration of calcium oxide and the reaction with rust and aluminum oxide. I just checked. Apparently this product no longer exists. This is its successor: www.dexpan.com/pages/how-to-use-dexpan-break-concrete-rocks-easily When I broke up that boulder, I drilled the rock with 1.5" holes as recommended by the instructions, mixed up the product with water and poured the slurry into the holes. 24 hours later, the boulder was rubble. It's amazing to see a hard rock slowly develop cracks and fall apart. They apparently sell this stuff at Home Depot.

[@XD3blaze]

Excavator guy here Your track controls should have a bottom foot piece that your heel can push down on to track backwards hooking the top with your foot is definitely not the way to go.

6:15 It more likely could be a BSPT 1/8” -27 thread. That’s what my Kawasaki small engine seems to be. NPT and BSTP are nearly identical with small differences. But they might have used a standard 1/8” not for easy replacements since the grease fittings might get damaged.

[@eformance]

Most mini excavators have a galley in the pin and you grease the whole shebang with the hole in the pin, so they didn't install grease zerks in the moving part. Also, before you welded it up, there were holes for a retaining pin through the bore on the outside, these are to hold the pin in place so the pin rotates in the stick, not the bucket end. Your setup was probably altered when they put the thumb on there and the pin is no longer fixed to the bucket end, so it wore. That's why there were no bushings in the bucket end to begin with, it was designed to be static with relation to the pin.

[@stephenlehr6020]

That was exactly what I was thinking, the rear pin of the coupler as a locking bolt that keeps the pin from rotating in the coupler, so all the rotation is between the pin and rear linkage. The original pin for that coupler was likely similar so no rotation happened between the coupler and pin (no need for grease or zerks then), just the end of the stick and pin. The longer pin for the thumb changed that and the coupler was not designed with replaceable bushings like in the end of the stick, so the cast coupler wore easily against the hardened pin. Hopefully the "new" bushings in the coupler will "wear" better with the grease zerks added. Probably would have been a good idea to machine a shallow grove inside those "bushings" in the coupler that aligned with the new grease zerks to make sure grease gets ALL the way around the pin (not just mostly on one side....) That is the most wearing joint on the whole machine.... Just keep that pin REALLY well greased!! All that said, great job on the repair!! On the foot pedals, just weld some extensions on the rear portion of those pedals that are horizontal (parallel to the floor), so that the heel of your foot can rest on them and push down for reverse. On many machines they are hinged so you can flip them up to lay on the portion of the pedal you already have, so they don't take up extra floor space. But if you are going to use them, they do really need to be flipped up "out-of-the-way"....

It looks like the easiest way to pull those pins out would be pumping grease after removing the snap ring.

[@tutekohe1361]

Good thinking! 👍

[@gorak9000]

Pretty sure that's why they're NPT thread - to thread in grease nipples. Pump grease in, grease pushes the pins out from the back.

[@jjock3239]

Peanut butter or coconut oil, which is solid when cool, both make less messy and less expensive substitutes for grease to do the pushing. I even used bread, made into a mush, for smaller jobs.

[@gorak9000]

@@jjock3239 Do you fill a grease gun with peanut butter or coconut oil? It takes quite a bit of pressure to get those pins out (though maybe less if you remove the set screws!) - I don't see how else you'd get enough pressure on it to actually make it work? I've seen the bread trick before - you need to use some kind of a punch to force the bread in, and I'd think you'd damage the threads on the pins doing it that way in this case.

[@THEBULLETPROOFGARAGE]

Great job on the repair! And I appreciate the stubbornness on the rock! I would have done the same thing! Keep the videos coming! Scott

[@hotflashfoto]

I know this is too late for this repair, but I thought of a way to get that pin centered in the oblong holes. 1. Repair one side with a new bushing, then insert the pin so it sticks out of the second side just a little. 2. Drop the new bushing onto the pin, then mark where it goes. 3. Machine the oblong second hole so you can insert the bushing. It should be lined up quite nicely, even if it's off a tad. But it should be pretty close to dead on. I like your videos because they show me things that interest me, and which I have never or hardly ever attempted. Thank you for sharing! After having watched a number of your videos, I'm subbing on this one.

[@daiseaward4686]

Hey fella…great bit of work. Will offfer an idea for centralising the second hole with the first. Dummy shaft with centre hole (maybe use the new bucket pin) put through first hole after you have bored and drifted the bush in..Use centre hole to centralise the boring tool exactly in line X+Yaxis. Great video thouroghly enjoying it… 🎉

I wish you lived close my farm, I would pay you to fix my sloppy excavator bucket. Great job and very interesting video!

[@DMHRC]

You're doing great with the old Yanmar. One of my best homemade tools is a pair of vice grips with a nut welded on top. I thread a small slide hammer into the nut and pop loose anything I can get the grips on. Works great on oddball projects like this and very simple. I even use it for stubborn cotter pins. Might be something you can use.

[@glenpaul3606]

Great video Jon. You did very well fixing those bad holes with new bushings. Your skills on the mill and lathe are admirable. I just like the way you approach and fix problems and your video/audio is always terrific. Good luck and Godspeed.

[@1978grizz]

When removing those two small pins for the small quick release cylinder, instead of hammering away at it use long bolt like you did, but let it do the work for you by putting a socket that's bigger than the hole you're pulling from and a nut to back the socket. Hold the bold and tighten the nut. It'll pull the pin right out regardless if it's held by setscrews.

[@tutekohe1361]

Larger Excavators have full sized foot ‘plates’ on the travel pedals that makes it comfortable to use forwards or backwards. I can see the video does not show just how much work there was in doing that ‘line-bore’ job, but it’s done now and you must be happy with the results. Great video.

[@CGT80]

The Vio 35, a little smaller than this machine, also has plates that extend backward and up a bit so you can move the tracks backward. On all the machines, up to the 349 cat, my brother and I walk them backwards if we have any distance to go. It is more comfortable to pull the handles or push my feet straight down instead of away from me.

[@megape95]

@@CGT80 well every excavator operator should know your undercarriage is wearing 3x more when travelling backwards. That is because of the top side of the tracks are being put to tention and bushes are turning under tention inside of the sprocket tooth. That is not happening when travelling forward. I think with a rubber track machine it does not make a difference, but with steels it sure does.

[@CGT80]

@@megape95 I will have to ask my brother if he has heard of that, since he is the well seasoned operator. Our company owns the mini ex but sold off their 320 and we rent the others as needed. The mini is what really gets walked a lot while the others don't usually have to go more than a few minutes across a work area. Thanks for the tip!

After you get set up for boring the second hole with the pin indicated, you can run a small indicator on a shaft in the chuck down through the top hole and indicate the bottom hole. Then adjust X and Y with the table so you are on center. Good luck and keep at it.

Really like watching these videos when the guys are really skilled at what they do. I've been a Tool & Die-maker and worked in the Military and aircraft missile industry for 40+ years. Had you done the one side complete then used a tight fitting pin and a V block you could have lined up the other side right on the money. But what you did will hold for anything you will put the machine through and last for years. I'm looking at buying a mini Ex for my small property. Learned a lot about what to look at from your video, Thanks. I also subscribed looking for more to view.

[@OldSneelock]

Great job on the pins and bushings. I am always impressed by you using what you had and making it work. A shop made line borer can be made from a couple flange bearings and 8 bolts to weld onto the item to be bored. Very similar to what Kurtis of CEC uses. Drill a piece of round bar, smaller than the hole to be bored, to hold the cutter and cross drill for a set screw. Slip the bar through the holes to be bored and shim the bar until the bar is centered in the existing hole where you want it. Using bearings the size of the round bar with a nice slip fit in the bearings insert the bolts in the bearing flange and snug up the bolts with double nuts through the flange so the heads are flush against the part to be bored. Weld the heads of the bolts to the part to be bored. Now the bearings will guide the cutter mounted in the bar. You can use whatever you have to drive the cutter. A drill motor, mounted motor, belt, and pulley, even a hand crank if you are really limited. Light cuts are best unless you want to rig up a way to feed the bar in at a controlled rate. That is essentially a home shop version of Kurtis of CEC's boring machine. When I was 20 the engineers at the Midwest Foundry rigged up a similar system to bore out the main bearings on the muller. Three guys sat in the muller, each shift, for three days, holding onto an angle iron handle bar while we bored out the 8" diameter bushing. In later years I realized I could have welded a couple posts onto the top of the plate and let the cutter just guide itself. It was a miserable, hot, dirty job, but it worked. It was much easier than tearing out the muller and sending it out for repair. Small tip for welding in things like the gussets for the thumb. Bevel the gusset and thumb frame to 37 degrees on the inside leaving about 1/8" on the outside edge to register the gusset in place. Tack weld both sides. Weld the inside with stringer beads until the bevel is completely filled. Grind the outside until the bottom of the weld bead in the bevel is exposed. Weld up the outside with stringer beads until filled. That gives you 100% penetration and helps prevent the joint from flexing On the rock try feathers and wedges to split off the top of the rock. The method is used in quarries to cut huge blocks from bedrock. It's tedious to drill the holes but the wedges work great. I had a company remove reinforced concrete air compressor stands at UTC. The guy wanted to try a couple different things and I told him to just make sure they were gone and no damage occurred to the building. They drilled 1" holes in the top about 6 inches apart and the thickness of the stand on both of them. One stand they filled the holes with expanding concrete. On the other they filled the holes with water and inserted a tube with a threaded cap on the end into the hole. They removed the cap and inserted a 12 gauge blank shot gun shell into the tube and screwed the cap back on. The cap had a firing mechanism in it. They fired the shell and the concrete cracked between the tube and the four holes around it. It took about 20 shots to break up the stand. The expanding concrete cured and pulverized the other stand overnight. The shotgun shells were interesting and rather fun to watch. The concrete was quiet, easy to do, and cheaper.

[@benjamincresswell3713]

John, you could've had fun with Dynamite on that rock. My Dad used to drill holes and pack them with Dynamite. He'd blow up rocks and stumps all the time, but he always told ME to drill holes and wait until winter to fill them with water and let nature do the work. Another fun video watching all the machining but I am glad you did the tail end with the rock and stump to give it the final purpose. I always look forward to you videos. ben/ michigan

[@paulj5813]

Look up breaking rocks with feathers and wedges. It's old tech but for the occasion need, it works and it is alot lower cost than a hydraulic breaker. You can order them from Amazon. I would recommend a set of ten in the 5/8" size. My property is largely rock with a little top soil or so it seems. I am enjoying your videos, keep it up.
