Dammit, catch something on fire again! Haha, I swear you and I C Weld are the best at this big equipment stuff, and I like how you both do it differently.
Don't waste your time listening to all the negative comments. You're a great welder. If they think they can do it better then they can get their own RU-vid channel. Keep up the great work, I love it.
Hey that lunette job was great. That's real life and you crushed it. I'm hear to learn and watch skill at work. Your apprentice is lucky to have a good mentor.
For the mismatched profile, I would ask the customer to push on it with a dozer or something like that. I've done that with a blade skin that was bent more than it should. Welded the heck of top edge than had the dozer push on a ripper of another. had to move a few times to get it all pretty but turned out really well. Customer was happy because he got his dozer back that day instead of waiting another day or two to get the skin rebent.
Four our rental fleet we replace those 3/8" wear plates and weld on about five 1" X 2" bars going across spaced 2" apart. Its a bit of welding, but the fit up is easy. Don't have to deal with inconsistent castings.
Great video. Looked like the plate fit fairly well. I mean its not a grand piano. Nice that your helper can work independently. Really speeds things up. Thanks for the dialog. look forward to the next one
Hey Paul, at the 7 min mark, you spoke about removing the remaining weld. I have recently been a convert to using flat carbons. I run a Pro Arc torch and they have an accessory button that replaces the original. I’d imagine that red arc have the same. It’s a game changer, try it, you’ll like it.
Hey Brother I always love watching you wield the Gas-Axe. It takes some practice to have the level of expertise you have. I agree that replacing that relatively thin piece of steel with anything thicker gives greater shear resistance and will counter the ETF (engineered to fail) part that Cat used. I found a 50 gallon 5 horsepower compressor along the side of the road and I thought it must be someone's that fell off a truck. I came back six hours later and it was still there so I threw it on the truck and am converting it to a gas compressor. Now I have a suitable compressor for Arc Gouging. My Harrible Freight 30 gallon was too anemic to do the job. I did not realize just what has to be done converting a compressor over to gas but I believe it is worth it.
Store your "rattle cans" up-side-down. That prevents the "solids" in the paint from collecting where the opening to the pick-up tube is. You still want to shake it up really well. Works well for me.
Dude thats a great idea to fill that gap. I dont see anything wrong with it. Its just a consumable wear plate. Now I with that I went and helped inspected a blast room built to AWS D1.1 specs. We caught them slugging some double bevel flare groove welds with rebar. We made them cut it out. But for this I see no problem but I also dont have the experience like you to make the judgment call. Rad stuff as usual. Also the video of the one handed overhead weld. Thats like a beer poster right there dude.😅🤣🤣🤣🥲
i subbed up.. enjoy your vids, i am down sick and i am going to watch every vid you have on this channel in it's entirety , thanks for the quality entertainment .
They make them 3/8 thick so they’re have to be replaced often at 500 bucks a pop ! If they made things that lasted forever they would make any money selling replacement parts And I bet those price of those plates have gone way up now hell I’m paying almost $500 for a 4 x 8 sheet of quarter inch mild steel Here in New York Question have you ever tried the flat carbons they’re perfect for Knocking off those old welds you could even get a nice bevel on a piece of plate if you had to with those I use them all the time And another great video
When my youngest son used to be in school and help me on Saturdays, he would whine and complain about having to grind. My reply, “Who do you think does it the other 5 work days of the week”?
Man if your wisdoms gave you as much grief as mine it's a wonder you weren't chewing that wear plate! Over here in the U.K. dentists went through a bit of a "who's going to sue me" panic - or their insurance Co did so my regular guy had to refer me to a specialist unit to do extractions and organising that is a pain so I kept putting it off and suffered needless agony. Mind you, my teeth were so impacted I reckon they used a gouge to dig'em out. You did well putting in shift while yours were nagging!
Awesome ! I myself also use 3/4 but I put on corner plates also especially on 51s 57s because sometimes they get pushed around a sweeping corner in the cut and with 9L and 10N even with cushion push dozers they can tear the corners up fast on a stinger especially pushing with a ripper cat with a conventional dozer blade. You have to hook it in the corner to keep from popping the tire with a corner bit.
What if instead of a solid plate, you ran horizontal strips about 4” wide. Then you wouldn’t need to template or get anything bent. I would think it would wear just fine, a bit more welding but a lot of time saved in fit up. Might be worth a shot on the next one
You have to know that an MBA was involved in the design process to guarantee future sales of replacements for a poor design. That’s what happens when you incentivize cost reductions over reliability. As a retired design engineer in several industries, replacement parts was always factored into new designs and revisions to existing designs. You always want the customer to be spending money with you…happy or not! That’s one of the reasons I left manufacturing and became self employed for my last 20 working years. I could take care of my customers like I wanted to be cared for.
Next time heavy tack the top of the plate and then run that machine up against a dozer blade, tack the middle, at least the top and middle will be solid. Then fill in the bottom how ever you'd like. As it is now your welds could pop when the plate flexes, cool video, nice welds!!!
I often put spray paint on top of defroster to heat up on way to job. It sprays much better but shaking it up more is necessary too. Another thing, if your can runs empty, invert it and clear then save tip. Nice job brother.
Hard to get that curve to match just right. Like plating a dozer blade. I did one once with 9 inch wide plates run horizontal. Pre curving like you did is the way to go. I used one half inch on the dozer. It was pushing single engine allis Chalmers scrapers. They were cool old units
Chrysler invented this made to break tac tic back in the early 60's with the plastic timing gear in their engines. And every U.S. company since has adopted this to their products. It's even been adopted by Japanese companies. So a machine that cost someone $200 thousand really cost them another $200 thousand just to maintain and fix for life of the machine. From cheap low grade materials and short cuts during weld assembly. 😣👍Thanks Alot Chrysler!
Mike k the plastic coated gears were to reduce noise and also as the chain stretches it won't dig into the plastic like it will with steel. At 100 000 miles or so the chain will begin bitting into a steel gear and stuff off small flakes of steel. Eventually the flakes are everywhere in the motor embedded in every bearing. Had this happen is how I learned it. The plastic can usually go 150 000 with no effect to the gear. The upgrade is a true double roller problem solved. Cost more but the alternative is to run standard iron replacement and replace at 70 000 or so.
Ya just gotta love jet arc! I know I do. I describe it to people as being like plasma cutting but being able to control the depth. I have never gouged with a plasma unit, and I'm really not too interested, Anyway, great video. Looks like it was hard to find that perfect position when doing that overhead. Looked like it was just the right amount of too high to be comfortable.LOL Be safe!
they use them to keep you in service....or the dealer I use to burn 5/8 rod all the time. i loved it but you gotta have the fresh air hood. we used 3M boxes for breathable air when I was working in powerhouses and confined spaces as a pipe fitter. i miss that.
Always think back to what my buddy the welder said. He worked at a trailer/ dump box manufacturer up here in BC Canada. The air arc or as they affectionately called it the unwelder. When ever the crew heard it every helmet in the place lifted to see who screwed up
Also if you were that company's full-time welder you could have welded the top and most of the sides and let a few days' running massage the bottom into shape then weld it. Either way it isn't going to fall off, and even if it does it isn't safety-critical.
Why do you suppose Cat put a layer of grease under the wear plates? Nice camera angles in this video. I especially liked the 1st person view as you welded up the left side of the plate. Would be fun to get an angle from beneath a plate when you’re using the plasma cutter. 27:28 strike a pose! 😂
I would guess the thinner and smaller dimension replacement wear plates were like that due to the problem of matching the face profile. By using the smaller, thinner plates you could do something exactly like Robert Palmore indicates to shape the material, as needed, in the field. Every impact area will be different depending upon the shape of the surface that contacts it, causing it to wear attempting to replicate the shape contacting it. The smaller, thinner material can be shaped on sight, whereas, the thicker, larger dimension material needs to be back filled like you are doing, leaving open space between the parent material and the new wear surface. As the plate gets thinner there is a point at which it will begin to flex, due to the open space between the two surfaces, resulting in cracking and possible earlier failure. Just a thought, regarding reasons behind Cat selling the thinner and smaller dimensioned material.
That is a good point but even those 3/8” plates are very difficult to manipulate into shape and will still have a gap under them. Either way it’s a pain.
@@OFW I wouldn't have thought of that until I saw Robert Palmor's post, where he indicates he has done something similar when applying blade skin. Right off it seems logical to apply a thicker wear material, lasts longer, should be stronger, etc.. I began to consider the thinner smaller size may be a factor when faced with application in field conditions. Considering at a very small instant in time while the dozer blades and the wear facing are in contact, nearly all of the force can be applied to an extremely small area, thus unthought of stress my be applied in ways we do not anticipate and metal oil canning might occur. This extreme stress might be applied time and time again throughout a work shift. I didn't mean to suggest your approach is wrong, but after Robert's post I began to consider why the heck would a company like Caterpillar sell the smaller, thinner replacements. Repairs such as this are often best done by old timers that have found things out via the school of hard knocks over many years that defy a persons thinking. I am 80 years old and have discovered ways of accomplishing things I probably would have never considered at age 30 or even 60. You do good work and I enjoy viewing your content immensely. My proposal was submitted for you to consider as a possible explanation as to why Cat might be selling the plates they are. Nick
I have a guess that they use 3/8 plates because it’s easier to bend to get the right radius. Also you talk about porosity is that when you get air pockets in your weld. If so how does it get there.
You mentioned going to AR400 steel for the west plate and the longevity of the AR400. What kind of wear/increased wear results on its mating wear surface as that too is a factor especially if the other wear surface were not configured for field replacements
Cat is made cheap but costs dearly. A thicker plate costs more. Cat make more on parts than on equipment sales. A cat sales representative once said: we sell at a great price, get customers hooked, then burn them on parts.
@@jeremyhanna3852 check your polarity, should be using DCEP (reverse polarity) I’d be BSing you if I said I’d never forgotten to set them up correctly.
What would you rather have. A customer pay you $1 a hundred times or a customer pay you $50 one time? That’s the mentality now days..you can guess which one they prefer.
I would guess the softer metal might take the initial shock better, like pushing on a pillow on a couch when you sit down. I said it was. A guess! Don’t laugh so hard😂
How is your apprentice working out? How Mandy years is the apprenticeship? I learned to weld in my electrical apprenticeship. Thanks for having an apprentice, the trades need more ojt training.
Hi one of the best welding videos around bye far what wire and gas are you using and is that spray mode your using all the best mate Hoo Roo from Paul from Australia 🇦🇺🍻
Like your work. New to the trade, afe you mig or flux welding that plate on? I ask because I can hear the wind. As why not stick weld it? Thanks for the insight.
@@OFWHmmm i thought about bending cardboard but i couldn't figure out how you'd keep the angle once bent and removed (wouldn't it bounce back a bit?). Did you tape it up?
well there you are you have answered your own question. they sell you the plats so that why it so thin Turnover & income son. now the math how much a plat multiplied by the Number of of cats required replacement & lenth of survive That your answer 6 million quid. extra earnings. Les England . As del boy would say A nice little earner . Rodney LOL .
It simple. Just like auto or electronic manufacturers they intentionally use substandard parts knowing they will be a hi failure items to try and force you to use dealer maintenance and parts. In cars Manufacturers charge the dealers more for this. And dealers make it all back in parts and labor. Now with equipment and electronics being sold and fixed buy the same companies it allows them to double dip and void your warranty when you have someone else fix it.
Grade 90 armor plating it'll stop at 223 to stop mosin degant an AK-47 Is my guess it's really hard it's not brittle it'll take an impact good stuff Maynard very expensive
