As a individual engineer your (hard earned) skill is second to none but as a species the ingenuity of humans never ceases to amaze me !

I have to say i have zero desire to ever weld or repair heavy machinery but the professionalism and level of skill in these videos is absolutely top notch been watching for years and its been said many times but you SIR are a cut above the rest

I enjoy your line boring and bore welding videos immensely! I hope you include all of these jobs in your videos. Thanks! Oh, and by the way, Australians pronounce that as Haych link!

Morning 4 am , Coffees on!! Cheers!;-)!

You make line boring look easy but I know just enough about machining to know this is a lot harder then it looks. Great job!

Make sure all the welding is done first before you do your final cut. because after you touched up the side of the faces it drew the bore out of round. set the bore welder to 17 volts. Anything more than that is just heat and spatter. Run the bore welder in the other direction, because when the nozzle spatters up and sticks to the bore inside, the darn thing will unscrew itself as it's turning around. If you put about a .006" crush fit on them bearings you don't need loctite. Also, if your chips are blue you are still running too fast. That's why you're getting a little bit of chatter across your bore. The cutter tip can't handle the heat and it erodes down. Not sure if you're using high speed steel or carbide but you need to use carbide. With a sharp point on the bit. Must sharpen tool bit after every time it goes across the bore. That weld gets hard

On the previous video of this seriers. You ask if there was a better way to cut the angles on the face wearing plates. 🤔🤔Imagine a reversed lathe chuck. 👀👀A 2" deep pan disk ?DIA? trepanning tool that bolts over the line boring bar holes. The tool would have two or four angle insert bars or HS steel cutters that can be adjusted in and out. Cutters will rest against a gusset and side bars inside for support or in slots cut out of a thicker wall resting aganst the back plate. This will cut strait on and would give you more leverage and force.

👍 хорошая работа, но я применяю жидкий азот для установки втулок.

I don't know what hurts my brain more -- watching you do this, or wondering how in the hell someone invented a line bore. I know one could say that about anything... I just find it all so fascinating. I just weld for fun on projects for my cars.

As always great job very professional ! 👍👍 I worked in printing right out of high school for 21 yrs we had older presses and customers preferred our work because of tge quality we could put out they said it was true craftsmanship because of the work was a bit harder to do to achieve good quality and they knew we didn't cut corners to get the quality ! I see this in your work and the craftsmanship and the extra time you take to make sure it's right !

3 👍's up on fire welding thank you for sharing 😎😊

That chamfer tool is neat.

Very impressive the old freezer trick is cool knowledge

hi Greg....thanks for making my Sunday morning......Paul in Florida

Whether you keep that bushing that closed up so tightly is your business, but I'm glad you have it on film.

You got a interesting job ,

Greg I enjoy all videos and your professionalism is top notch there is nothing like having a bowl of ice cream and watching your videos😊

On the hydraulic press, I use spacers that are notched (as with an arbor press) so I don’t have to keep removing / rethreading the nut. Helps a bit with shorter throw rams 👍🏻

Nice job, if you get one of the 6" wide luggage wraps and you can wrap and seal ends of repaired items easily which provides excellent protection and only takes seconds to apply. Ray Stormont

Bon Boulo j' aime,😆😆👍👍

Excellent work 👍👍👍 . Thank you for sharing. Take care of yourself 🇨🇦

Very skilled to do that job.Thanks for the great video.

Wow! You make it look so easy! Nice job! Greg! 😊thanks for sharing! 👌👍

Flapper wheels are awesome, do a nice polish

I find on these big newer cat equipment (349/374) if you only do 1 pass of bore welding it gets hard af…. Its gotta be something in the material.

You say the material was hard, but wasn't it your line bore weld that you were cutting? Great channel, love it!

Awesome,thank you for sharing, i learn a lot , always a pleasure watch your project 👍👍👍👍

sangat profesional❤

I appreciate the video. Good filming and interesting work. Thanks

That is so cool, A lot of prep and work, but it's great work 😊

Great job

gotta love those 3M Cubitron II discs...... so much faster and better than a hard wheel or a flap disc......

Nice work sir you should show us one these days how line up a egged out bore with the bearings. Unless I missed that one . Thanks

Flap Wheels I believe......love them, especially the ones with sandpaper and Scotchbrite in the same wheel

Acompanhando seus trabalhos amigo perfeito!!!

You're fun to watch.

I noticed something, you were welding in short sleeves, my dad would do that once in a while oh the sunburn, then he wouldn’t do that again for a long time. I’m allergic to sunlight so I’ve worn long sleeves for 60 years.

I had some steel once that was really hard like that, and made those same color magenta/purple chips in the lathe.... I have no idea what it was, came from a surplus place......the chips were amazing and the color was unusual.....high manganese maybe? anyway, I was making rollers for a ring roller......looking good Buddy.....Paul

You do amazing work, thank you.

Those bores are terrific!

Excellent shop work, strong skill set!

👍👍

Cool 😎

Hello from TEXAS!

easy money! good job as always

عمل متقن ورائع 👍🏻👍🏻

I babysat Cat scraper spreads for over 30 years and I can’t even count how many H links and cushion hitches I’ve had to bore and weld up . A little different from an excavator H link but almost the the same . 😊 what brand of inserts are you using? Thanks for sharing. Those are called flap wheels on your Milwaukee. The red Loctite works good but if you want to really securthem use the Loctite 720 green color and those seals will never pop out . 😎

If you ever run into Hitachi H-links, don't bother welding them, they're cast iron otherwise it'll be really hard weld to machine haha

I call that sanding wheel a flapper wheel

I was just thinking you really weren't cutting the steel on the part . You were cutting the weld you did so you were cutting your wire you laid down.

Seems like it would be a better design if new bush had an exterior shoulder to bring it all back to spec

Weld a couple beads around the inside and the bushings will shrink and come right out.

It is hard as the mig wire is higher grade wire and has reacted with the parent material. Seen welding angle iron Years ago and it made hard spots.

This might be a stupid question but I'm known for stupid questions lol... Once you make your pass with the line bore and it's concentric, why not just order or make a bushing with a larger OD? I would think it would provide longer wear life and you can avoid all that time consuming line bore welding

Where do you get your measurements from? Like how do you know when to face and how much to face to and things like that? Does SIS have info like this or what? Thanks, nice work as usual

What do you use on the far end of your enerpac? The end far from the ram itself. Because you’re washer/spacer behind the nut just gave me a good idea for my set up on my rig.

👌🏼🤘🏼🤘🏼

This time have you made the small lip on the inside in order to fix better the bushing ? (Like you did in other videos).

How much of a interference fit do you use when cutting your bore to its final dimension do you use one too one and a half thousand of an inch for every one inch dimension of the bearing or do you use something else just wondering on your professional opinion thanks

Can you tell what are those inserts?I use hss or brazed carbide and sometimes material hardens and breaks them

Are you trying the bearing retainer as an alternative to cutting a step/bearing stop in the bore? No opinions, just curious if this was an attempt to shave a little time off the project.

maybe someone had built it once before using a much higher tensile strength rod? Also, do you always run inline bores dry?

i wondering how much price this boring machine 🙄

Why were these bushings so dark colored.? Usually they are pristine clean.

How much can someone make on line boring. Do you rent the CLIMAX LINE BORING MACHINE

Did you ever try to put the bushings in liquid nitrogen ?

I’ve been at this for roughly a year, love it to death, just wondering what kind of bits those are and if you have a link to where I can get some for myself

What are your settings for welding the bore?

I’m wondering who is that boy with you?

Greg, I cant seem to find that air tool for chamfering on your Amazon site????

I've seen people weld on bushing an let cool they knocked it out

How many thousandths do you allow for a crush fit on such a long bore?

Cutter recommendation?

Whenever you are installing new bearings, there is always that fear that they will stick half way in.

What filler metal and brand? 70S6?

your cutting insert isn't wearing out is it?

I'm just passing through getting well educated

608 bearing retainer ?

Вітання вам

5:08 did you notice the jump when it was line boring?

Its surprising of all your toys you have you don't run a plasma table for making parts, they're so inexpensive now, relatively speaking.

It appears unpleasantries have occurred.

Looks like your last line bore was not parallel. I didn’t see you correct for that which means the bushing disintegration will likely reoccur.

ขอบคุณสิ่งที่หน้ารู้ครับ🇺🇲🌏🤝🇹🇭🛠️🚜♥️☕🍺🙏🍻🪕🪘🐖🐐🐓🦆

You might of been cutting to much on that hot pass.

to me is the wrong grease you Americans are using there should be Canadian grease and oil never have any more blown engines or worn-out holes better dancers bone we have here the Indian and cowboy bones you have lol

Hey Greg! your workshop cooling fan! If you put it on full power would it fly around your shop enjoying your content sir keep this sh1t up outstanding 💯👍🏻🫵🏻
