Caterpillar 235 Bore welding and Line Boring continues

Progression of the Cat 235 project

[@copperheadmarine]

Its very organized and interesting to say the least. This man has a great personality and is great about explaining what he is doing.

[@caseman7896]

I highly respect your welder. He is highly disciplined and ambitious.

[@bert26a]

Love seeing the new videos Charlie and how it's all done, not something you get to see every day.

[@blacksmoke5009]

Great video thanks for sharing! That’s long hard work and it takes a skilled craftsmen to salvage that worn out junk !

[@patdexter9188]

For best results i have found to run the beads length wise in the bore. When welding by hand. Overlap about halfway everytime. Been doing that for years. Looks good tho. Everyone has there own way.

[@michaelwarlow4398]

It takes one to know one where I come from great video outstanding skills thank you :-)

[@merlepatterson]

Gotta love those custom stand-offs he made for the line boring machine. Make them as ugly as possible but also work beautifully.

[@kamboy71]

Good to see you uploading more videos. Always interested in what my former fellow Northern Ontario friend is up to.

[@lawrencehp1]

Great stuff as always

[@copperheadmarine]

I have looked at line boring riggs several times but they are expensive! All this work will be less than $2500. I had even thought about doing something like what you have done. I hiered this fella because I just don't have enough time to get it all done and he has a great reputation for quality!

Willco Jak what! If you read the comments here he's the stupidest person that ever put on pants! And I'm right behind him for hiring him! But! This machine has dug 20 acres at my pit 16 feet deep and it's still as tight as the day we put it together....but I'm looking for it to fall apart any day now...it has to! Just read the comments!!

[@spudpud-T67]

@@copperheadmarine Been welding for 80 years / 25 hours a day and this guy is welding all wrong. I'd do it just right and much cheaper and ... mummy's just bought in my coco.

[@nitrostreet-]

I used to hand weld the bores like that in the early 90's for the CAT dealer I work for - lot's of work, we've got 3 Climax borewelders and boring bars now. On something like the center stick hole you show there you can set the Climax boring bar up and have the bore welded up in about 30 minutes, then put the boring bar back in and start boring 5 minutes after that, they've got a pretty good boreweld/boring bar interchange system with those.

[@brisson182]

[@TechniPat1958]

very nice work

[@I_leave_mean_comments]

nice setup that guy has.

[@I_leave_mean_comments]

Its funny to see so many people in the comments talking about how "his welds will never hold". Seems like they don't understand exactly whats going on here. He's bore welding. He's adding metal in the hole just so he can bore it out to the right size.

[@duylcttunglm7304]

Zeet .

[@214mannygarza]

Zeet sorry I was thinking that as well that those welds look well not so good but your just adding material.

[@alexkoenig4893]

The thing with virtual an down welding in a bore is that you don't get enough heat into your pass which makes for areally hard cut.

[@beast7018]

Zeet they "think" they know what they're talking about.......I'm pretty confident this probably isn't the first time they were wrong

Wow, that is a big job. It will be like New when done.

[@Graveltrucking]

Looks like that guy has a fully self contained shop on wheels.

[@dadsvespa]

This guy is a master welder. And old man, who was a welder during WW2 taught me this same technique . You build up the area to be bored back to stock size...or whatever size you need. Usually done because boring into the worn steel, to install an oversized pin...would actually weaken the joint. Sometimes as in an engine with severe wear or damage, you bore out the block or part and install a cylinder with the stock inner cyl. diameter restoring the bore to stock size. I'm rambling...matt. .

[@wonhuanglowsoverylow5000]

A master welder. You are clueless.

[@lindsaythomas2283]

[@jhonyfordchannel8747]

Nice job bro

[@Travisfromoregon]

I love air/arcing. !!!!

[@copperheadmarine]

He pressed the bushings in with 50 tons of force. He said to weld them would distort the bushings and bore? He is very precise. The air arc never left a mark on any of the bores that I could see. I have learned a lot from him in a short time. I did ask him about the sleeve retainer and he just smiled. He said that's for factory bores that require 1 to 3 tons of force to press in. But if he had not insisted on not needing it I would have locktited it and welded it so we think alike.

[@astro1218]

Thanks for the video :)

[@ryanlewis9599]

I sure would like to have a full setup like he does. I'm working towards having a small repair shop. Got an everlast welder and plasma cutter, bunch of grinders and tools. Need a generator to take it mobile.

Wow you are soooo smart ,

[@zoggrog8823]

Thank you for a nice video. There is ALWAYS more than one method. The methods demonstrated seem sound to me. Never-mind the moronic trolls and KZbin "experts" in the comments. I do admire your tongue in cheek passive aggressive reply comments. It is VERY easy to see the ignorance of these people, simply by their comments.

[@gangesexcavating]

I notice you have the upgraded H-Link. Cat originally had a Manganese alloy one-piece cast H-link. All good until it cracks. Ours did. We didn't know it was this special alloy. I welded it, pre, post heated it, and slow cooled it in a tub of floor dry, wrapped in asbestos blanket. Still cracked 10 hours later. Found out it was this wierd alloy. Local shop wanted $1700 to weld it because of the wierd alloy and special wire needed. Upgrade is a mild steel aftermarket H-Link. Found one for $400.

[@gangesexcavating]

Our boring bar has a 3/4" hex head machined on the end. Now this can accept a 3/4" x 1/2" impact wobble socket. You need two universals to work correctly. So we put a 1/2" x 1/2" impact universal on top of that in tandem. We sacrificed a 8" x 1/2" impact extension and had it hex machined to accept to the mag drill chuck. The sockets were tack welded together. Now with the 2 universals, the mag drill turns the bar perfectly, full torque.

[@gangesexcavating]

The next time through we are going to go with a fabricated 1 1/2" boring bar however. The bar is still too thin to take all the vibrations out, we found, when used in any more than a 14" span between the spherical bearings. We found the the steel had become work hardened in the oval areas,this was significantly harder of a material to cut. We went through quite a few fly cutters, but patience paid off, and we brought lots of cutters. Your bar had to be broached. Round cutters vibrate out of set.

[@meandthemrs7403]

You oughta hear one of those air arcs inside a shop.

[@garthhaynes6848]

Genious!

[@markfryer9880]

Well, it would seem that this guy has all the bells and whistles you could want on a service unit. A crane on the back deck, a shelter to keep the weather and sun off, a generator, lights, welder[s], air arc, tool boxes, tool tubs for hand tools and one or more microwaves for keeping the operator fuelled and working hard. Did I miss anything? About the only things I didnt see were a fridge, a lathe and some sort of mill, but you cant have everything or can you?

i realize it's pretty off topic but does anybody know of a good site to watch new movies online?

[@ChrisJB84]

Awesome. I used to do this kind of work my self. I just built the bores up, ,and another guy bored em out. I like his rig, do you think you could get a tour of it the next time he is out?

[@gangesexcavating]

I don't know how much force we used to press ours in. We used 7/8" high alloy, fine thread ready rod, and ran them in with a 3/4" air impact. We ran 2000ths" undersize for an interference fit on the bore. We were additionally concerned about the welds cracking from use over time.Maybe we were being overly cautious, we don't exactly do it every day, you know. so we drilled, tapped and threaded a 3/8" bolt 90 degrees to the bushing, zip cut it off and plug welded it. Worried about bushing walking.

[@michaeldemar856]

To all the critics ,get your ass out in the field ,and get a piece of equipment back in service ,it ain't easy and it ain't fun ,just plain hard work .

[@pvtimberfaller]

Yup.

[@BoogieButts]

No shit bud, we had a link belt 1100 with tracks, get buried on a power line right way due to liquefaction, we had 3 cat d8's pulling it out in the process the mud and tree roots ended up getting under the turn table and busting one of the track hoses. Talk about a work out, we had to dig down and back and up inside the housing. Because the cab was basicly ground level.

[@el-nicko53]

What is it about welders that makes 'em want to constantly piss on each-others chips?

[@3dsman]

They must be related to guitar players. Same shxx happens there.

[@gangesexcavating]

We have built our own line boring kit. We use a reversable Milwaukee magnetic dill, with infinite speed control, 9" travel. It seems to be the only one on market with these options. Our boring bar is 1" 4140 stock, that was drilled and broached to accept 1/2" fly cutters with 1/8" allen set screws. Chinese cutters are junk...use USA made ones. The biggest killer in a great cut is elimination of harmonic vibrations. Travel speed, cutter speed control, and depth of cut are massive variables.

[@copperheadmarine]

I almost opted for the updated pin which is 4" diameter instead of the 3.5" pin it came with. It has an oversized pin, oversized bushings and seals . You then bored to fit but it was over twice the cost of the original pin, and I thought it worked since 1984? It would work for the rest of her days?

[@gangesexcavating]

We built our kit for under $1000. I think it cost around $750 or something. We used greaseable 1" Timken spherical bearings with 4-bolt mounts, on 5/8" square plates. The boring bar we made on our lathe at the shop, but had the allen screw holes and cutter holes accurately done at a local machine shop. After trial and error, we found we needed to 1/2" broach the cutter holes, so we bought a broach and did the job in our 50ton press easily. We rent the mag drill locally. Its big money to buy.

[@petermoale2116]

Ganges Excavating, Did you try drilling and reaming the holes for the cutting bit first (With a set screw to hold the tool bit) ? I would like to know how that turned out ? Is broaching a square hole better for rigidity ? Thank you if you read this.

[@copperheadmarine]

I'm hoping I wont have to worry with slop as long as we keep her greased!

[@gangesexcavating]

Did you use any Loctite on the bushings before pressing them in? We used Loctite Cylinder sleeve formula, and then pressed them in with a fabricated high alloy ready-rod press. We opted to weld the bushings in after. Figured we would fly cut them out afterwards if they needed replacing. Don't know if this is done by the pros, but we did it for security. Does he have issue with shattered fly cutters from the airarc scars? We seemed to have a bad issue with this.

[@nikolai502]

[@tylercunningham3275]

[@crm3480]

Could an insert be machined then either shrunk in or welded. Then line bore? Also, How do you align the boring apparatus exactly square to arm or parallel to all the other bores?

[@Clunk49]

Couldn't they bore it, drive in a cold sleeve, weld the ends of the sleeve to the piece then bore it out to size?

[@copperheadmarine]

You welded by hand as well?

[@forrestgumpv9049]

Why not use an Aluminum/Bronze bushing/sleeve and just replace it and the shaft. I don't know if it can take the pressure, just asking. I'm not being a smart ass. I am a machinist who worked at CPMT for 2 years, who made those line boring machines. Are the welded holes soft after machining ? or are you case hardening them ?

[@MarceltheParcel]

Why didnt he start from the centre and weld his way towards the outside

[@Apollo1van]

Where are you located I live southeast Mo.

[@30timson]

2 года отдал такой работе

[@MyMIXmedia]

Why bore weld when you can sleeve the bores???? It would be instant fix.

[@FlushtheSystem]

I understand he basically weld facing to build up to bore out. But his welds may not have good root penetration and only weaken the base metal and make bore very short lived. The new "hole" may very well have a shorter lifespan.

[@lancewinters1761]

Haha, your an idiot.

[@copperheadmarine]

By the hr. He will quote a job but it will always cost you more that way.

[@JAMESMANHUNT9]

i work 12-14 hours a week and do some other things after hours

[@gangesexcavating]

Hiring someone to do the job just simply wasn't an option. Our 235C is located 14 hours north of Prince George BC in camp. its 10 hours in on logging roads to get into camp where it is. The travel costs would have put the job well into the $7000-8000 area. So it was either pull the stick and go to town or do the job on the spot. We didn't have to bore weld, we just cut out the interfering material, and fit up the bushings accordingly - one shot deal. Pretty serious getting down to final cuts.

[@pvtimberfaller]

I never had much luck doing it that way, if the bushings aren't completely supported they will crumble in a short time. Esp the hard steel type.

[@alexkoenig4893]

Can someone explain how this guy finds center of the bore without having any kind of adjustments for his boring bat?

[@desertfox4921]

I don’t know shit about this but why they don’t use liner or sleeve so it can be replaced at any time

[@lancewinters1761]

They do, but when you don't grease the machine it wears through the bushing and eats into the boss, all this guys doing is building the bore back up to a accept a factory bushing. If you stay on top your maintenance you should really never have to have this done.

[@welderteach]
