- A common problem with late model Case and John Deere tractors in the front casting getting wobbled out. This repair will give this tractor more service life. Simple line bore and bush will cure this problem.
Brian Block does this repair often. Check out his channel @bcbloc02 He does some really cool stuff.

Josh, I'm sure others have told you that your threaded rod supports were waggling like a fish out of water.
If you haven't already done so I strongly suggest that you watch "Cutting Edge Engineering" out of Brisbane area, Australia. The guys name is Kurt, his wife, Karen. He does the work and she the video. They're bloody good at what they do. He does a lot of line boring and while I'm not suggesting you invest in his SIR machine some of the attachments he uses and makes for himself would cure your rigidity problems. He posts on Friday mornings usually and it's well worth your time.
Regards from Canada's banana belt. 👍🍌🇨🇦🕊️🇺🇦🤞

Look at all that free top soil!
Threaded rod was not nearly rigid enough to support the pillow blocks, you can see them shaking.
not only shaking, they were wobbling probably 30 to 40 thou.and no doubt causing egg-shaped holes
Only on the roughing passes, steady on the finish light passes. Works for me!
The quality of your video on my screen is perfectly fine. The content of what you produce it the most important.
My wife is an RN as well, so I appreciated your comment and agree.
I think lateral support for the bearing blocks would knock down the amount of weeble wobble, but is seems that taking final light passes does the trick as well. I can appreciate the hesitancy of taking a lot of time to build specially support (tooling) for a job you might not see again as opposed to getting the same kind of parts to work on continuously making the time investment worth while.
Compliments! Your workshop is very clean and organized. This inspires me to make my workshop cleaner.
Great video.
I took a junkyard engine block thru the car wash prior to dropping it off at the machine shop. They built engines for the truck series in Bakersfield where truck racing began.
The owner asked my why I bothered to clean it since they hot tanked them as a standard practice.
I told him it was too embarrassing as dirty as it was & that I take pride in my work.
When I picked up the block, it was nicely sealed and he told me I'm sure you are going to clean the block prior to assembly but I want you to know this block is VERY, VERY clean. I thanked him and off I went.
He was true to his word, there wasn't a drop of oil or grit.
I agree, clean the part prior to dropping them off, have some pride in your work, it's a reflection on you!
Great video, thanks.👍👍👍
Not sure I would have bored out so much material for the steel bushes. It has taken a lot of strength out of the area, which I would think has a high loading in operation.
Tall angle plates with vertical slots to accommodate the boring bar and bolts would be better. Then switch to flange bearings instead of pillow blocks. Reminiscent of a boring mill tailstock, just miniature. This would allow you to just slide the bearing up and down to align it.
Wait for next week's video. 😉
Gday Josh, nothing worse then having to spend hours cleaning components up that should have been done before drop off, I’m now using Hangsterfers 5030 cutting oil in my Cincinnati mill, I’m really happy with and I use a GoPro Hero 7 black with no external mic, it was a bit expensive to buy initially but it has been bullet proof, I don’t get complaints about audio, it’s been dropped, kicked across the floor more times then I can remember and it still works as good as the day I got it, I’m my opinion it’s was worth the extra outlay, great job mate, Cheers
Hi Josh Nice repair of the tractor part. Trying a new setup and making improvements as we go is just part of it. Thanks
Great job. Using the all thread opens my mind to even more set up options. Thanks and stay warm
Nicely done Josh, thanks for sharing buddy
Spot on, Ref having to clean parts before machining , same with service work.
Nice set-up Josh, maybe it needs to be more rigid?, pretty healthy cut there.
Thanks for sharing.
It did need more rigidity. I address that next week
Nice work. Always liked the boring mill. Also appreciate your manual expertise. Once I had identical jobs to do vs a fancy CNC mill, and I got it done in less time with 33% of the manpower.
I'm fairly sensitive to cutting fluids myself. It's only been about 6 months, but I've been using boelube and I'm really happy with it. No rashes, and it kind of smells good even when burning!
Good one Josh . I use Castrol Hysol MB50 . No issues & use it neat for tapping etc . 👍
G’day Josh. Great seeing your channel steadily growing. Love watching that horizontal borer of yours in action. Cheers Aaron 🍻
Thanks Aaron. It's been fun. Lots of ups and downs. But I am having fun with the editing and camera work.
Cool stuff. When you did the line boring setup I immediately thought of the outboard brace like those on the K&T or Cincinnati horizontal mills. If you could find a heavy rectangular chunk of plate and plasma cut a large slot for the bar, then two small slots in it and weld on a flange to bolt to the table.
Stay tuned for this week's video. It's another line boring job with upgraded support
Always entertaining Josh and a nice job
Very nice job.
The HBM is a good machine, versatile!
Great content Josh.
Thank you, EM.
Muy buenos trabajos amigo buen profesional
nice work Josh .
Another good job. Must take some time to set up those self-aligning bearings to the correct height.
Good job. I’d wondered why you broached those holes 4 inches apart and now I know. Anytime I can learn something new it’s always worth watching.
Just found your channel. I'm sorta binge watching. Liking the vids and I subbed too.
Try some pieces of I-beam for your bearing blocks, they stabilize the boaring bars great, great video Josh, keep'um coming..
I subscribed to your Channel because I'm from Wisconsin to Lake Michigan is a about one block from me and of course You're A Gifted Machinist
amen on the cleaning and low quality supplied parts
I don't know anything about modern AV equipment, but I do watch a lot of low budget channels and channels filmed in the third world. I'm convinced that the best balance between audio and video quality is using iPhones believe it or not. Many of these channels attempt upgrades and inevitably end up with worse audio. Then they need a stand alone Mike. Then the timing has to match up just right and creators complain about the upload times. I've seen this also with well-established channels that had a sudden camera mishap. The quality of these videos is really quite watchable. I think in many cases, people are buying older units from eBay that may not even have cellular capabilities anymore. I don't have any reason to plug Apple over Android, I use on Android myself. But the few channels I've seen this on have happened to mention they were using iPhones. I think if you need one or two capable of nothing other than shooting video and uploading, you could probably get a very affordable model
Nice Lucas we have a no41 probably from the 40s lol. We get the same problem everything just soaked in grease and oil and its 110 an hour to clean it up
You got her done, that's the main thing.
Rigidity is everything in machining..
That is as well as measurement,
Planning,
Tooling,
Machinery,
Paying for it all,
Getting paid for it ALL!
Get down off that box, old feller, before you hurt yourself!
Pity the tail stock, support thingy didn't come with that HBM.
You are going to make one.
Good video
🇬🇧😐
YES, tell 'em... Just like in our auto shop, car comes in empty on gas... "Oh, just go to the gas station, no big deal", YUP, $195 an hour :)
Hey, my wife is also studying to be an RN! Hopes to graduate in May!
Yes Josh sure will
Josh under your pillar block bearing stack old pieces or shaft with holes drilled in them to keep the shaft from running out
noticed a side to side movement of the far pillow block support seems like a more solid support would be needed than just two allthread rods
I used Prolong super lube in a drilling operation I drilled 48 3\4 holes without a pilot and the drill bit showed no sign of wear. Idont know about lathe inserts but it would be interesting to see The oil is mixed with water and does not leave an oily film.
Great job. That did look like a fun job except for the cleaning
If I might suggest sheer support for the bearings. tube on each side and web in between. Maybe multiple heights, 2, 1, 1/2 and so on. Mix and match as needed. even if you still have an inch or tow of all thread sticking out of the sheer support so you don't have to shim the support exactly so.
Stay tuned for next week's video. I made some new supports after this job. Every time I do one of these jobs, I come up with ideas on how to do it better.
@@TopperMachineLLC Coming up with new ideas is what I love about machining and fabrication. Problem solving. Fills a particular niche in my personality. Look forward to seeing your solution.
lots of support block movement
👍🏻
Good job. Yes, RN's are precious people and they do work hard. But, underpaid? No chance!
i like the split views
Im guessing you just wanted to try out the new line shaft bar. But I would have thought you could have done all the same with a rigid boring bar adapted to boring head. Have the job roughly centralised on table then dialled in with the aid of a parrallel bar through both holes. Then just use the turn table and vernier scale on cross way to align. Feed out head to obtain required bore dia. Ive done all that with a Kearns & Richards hori/borer before.
I would have liked to see how aligned they turned out. I assume the machine has one long pin to go thru both holes? Or two short pins in two short pivots. Otherwise nice to see a boring mill in action. Metal Raymundo is a master at the boring mill. I subbed and rang the bell anyway. I like your methods.
The customer got it back together without issue. But I would have liked to seen the finished assembly also. Thanks for subscribing.
Oh boy, nice snow storm there. Where are you located if I can ask? Snow is a plague that looks pretty but is a pain.
I've done a job or two that are similar. But, I bored out the holes enough to get a good bore and then made oversized bronze bushings. Or, bought bushings with the right ID and a thicker wall and bored the holes to fit. I'm just wondering why you bushed to original size but at the cost of having two parts there, not one?
I'm also curious about grease. Those bushings showed some grease holes in the bushing. But, the casting has no provision for a grease fitting. Are they greased through the pin, or is no grease after assembly why they wear out?
Contact your Castrol distributor. Use Hysol MB 50
Nice work - did you lose any internal diameter when fitting those outer bushes?
No,. They were bored to fit exactly. The bushings I made were heavy enough not to crush.
I'm a year late, buy OLYMPUS Tough cameras are quite good. I use a TG5.
Have you found a suitable coolant? I'd be interested to know if you found one that is good to the skin and the machine.
I believe the tractor part you are working on is known as a “bolster”. Looks like its off a CIH Magnum.
It is. I think he said a 2390 or sometime like that.
I have a question (for my own learning, not being critical). How did you decide the size of the bushings you made, specifically, OD? It seems like smaller would have thinned the cast support less and left it stronger? just curious. Thanks for your videos. Always enjoyable and informative.
It's really just a matter of personal preference. I wanted it thick enough on the wall as not to squeeze tighter when installed. There is enough cast there to not be an issue,and now it doesn't have slop to cause hammering. This making it stronger.
How do you get your boring bar to be true.( straight or leveled)
What was the size difference between the cast bore and the steel sleeve?
Can you send me a link concerning your new lath including all features including prices and options
Where do l find any response from you here on my iPad?
I was happy to see you mention Kurt from ceea
The blue bearings needed side support to stabilize them.
That lion looks nice...I've never ran a brand new lathe...what's it feel like??
Pure heaven. Lol. It's amazing how much better it is.
i now use Canon REBEL T06i, but started out with go-pros. I think Mr. Pete uses something from the VHS tape days and it looks ok. Abom uses GO Pros I think. I'm sure Canon has superseded my T06i by now but I am very happy. Don't need ultra small like Go Pro, but I DO like to be able to use different lenses. You can buy a NICE camera set up for just a few hundred bucks. BTW: I like RODE wireless mikes too, although they've become pretty ubiquitous. What editing software do you use?
I was using my Nikon for a while, but it is too cumbersome for the shots I'm doing. I loved the video quality of it but the setup was awful time consuming. GoPro was a waste of money. I now use DJI action cameras and love them.
It would be nice to have a tailstock.
I worked in the maintenance department in a large truck factory , a dirty part taken to the machine shop was not touched !
I think I work with that guy that forgot to turn on the microphone sometimes too. Had me nervous with that baller cut on the line bore.
Hmm... I'm surprised you didn't choose a more rigid option to lock the bearings in place, especially since that threaded rod allowed so much deflection and wobbling which would invariably throw any accuracy out of the window
you mention dirty stuff in for work i used to repair surfboards and people would bring them in with wax. and sand on them so i would have to clean it all off. To fix i would have to remove the wax and sand so i started charging for the cleaning
I was wrong. Google says that PN was used on the CIH prior to the Magnums. ;-)
so when you bored the tractor part did you cut the first hole to an arbitrary size and match te second bore or did you cut them both to an arbitrary size and match the sleaves seperately, only asking as i didn't see you measure really.
I just opened them up and then made the bushing to fit.
@@TopperMachineLLC that's what I was wondering did you make them both different diameters, or both the same?
So when you're doing a line boring job, if it's a rather long shaft it has a tendency to whip in the middle. Obviously you're using bearing pillow blocks to lesson this oscillation. How does one calculate how much bearing support and how far apart they need to be to maintain a set degree of deflection? I'm sure there's a formula in machinery's handbook, but do you have like a rule of thumb?
The rule I use, and this is for stick out, not span between bearing points, is 6-7 times solid shaft diameter. So if I am using a boring bar of 1” diameter, stick out had best not exceed 6”. For span between bearing points, maybe it is possible to almost double that? Otherwise deflection becomes a serious issue.
How much bigger is the bushing you made than the bore to enable the use of Hot/Cold to fit thanks
This one was about .003-.004 larger. I honestly don't remember, just based on size you go .002/inch of diameter
@@TopperMachineLLC Thankyou very much for answer
Was there a reason other than cosmetics that you did not choose to crest a weld on temporary brace to hold your boring bar more rigid than the all thread rods were doing you can see several thousandths in deflect as the cutter head engages the metal surface?
part being machined was cast iron, not easily welded to.
Anyone who hasn't done any precision machining doesn't realize how dirt will affect the quality of the overall product.
Did you take metal shop in high school? Always wonder how a guy gets his start.
Yes and worked in a punch press shop. Learned tool & die.
Josh the threaded rod fixtures have way too much flex. Blocks could be a better solution.
Shrink fit instead of Dutch? What does Dutch refer to in this context?
Set screws in the face. drilled and tapped on the split line between the bushing and casting. Usually 3 equally spaced
If you have the materials and the products available, use liquid nitrogen to shrink the fitted part 1st before insertion....machine it to 1-.002 over the bore...will generally shrink .004-.006 , but when it warms back up and expands, it will be so damn tight almost like its welded in......just saying
I am in a desolate area. Almost nothing is readily available to me. So we make due with what we have. I have used dry ice when it's super critical. But again, not easy to get here.
@@TopperMachineLLC I totally understand that, I also live in the sticks....I have air-gas my local supplier refill my cryo insulated bottle 1x a month during my sched O2/Argon/Acty/delivery,
cost is comparable to a argon refill and can last all month
I have some camera equipment 2 canon eos rebel t6i dslr camera and a cheap gopro clone. Might be able to make a trade for some boring work no my south bend headstock let me know I'm in Wisconsin
I just bought a Nikon D5300 and love it. But, I'd be interested in helping you out with your project. Give me a call or email. Let's talk.
@@TopperMachineLLC cool thank. I will I'm over by menomonie so not to far away
Great content Josh, I really enjoy watching your work and repairs. A couple viewer comments. I know you had a problem with your gas supplier, other shops etc., but to continue bashing them is very unprofessional. It's not worth your time to continue including that in your videos. When machining a part to close tolerances it is very hard to watch someone beat in a metal part with a ball pein hammer. Very poor practice. Using the long al-thread for your bearing supports on the boring bar application with nothing to give rigidity to your pillow block bearings is not quality work. Yes, it worked but you could see in the video the movement. That is not giving you a good fit. You should add some mass to the bearing supports to correct this problem. I hope you consider these observations as constructive criticism to help your business continue to grow and get more viewers of your channel.
Thanks for sharing.
I know a lot of locals watch me and I am just sharing my experience with these local vendors, in the hope it will save someone from the same problems I had. Watch the next line boring video, as it solved the movement problems you saw.
I always tell customers they can clean it cheaper than I can.
Nice work, My sarcastic, devilish side thinks I would put all the dirt back in a bag and send it back to the farm, But then again that's why I don't own my own business.
Почему качество видео плохое? Нужно видеокамеру получше купить.
well straight off if a job came in and needed cleaning like that one did it would have went back out the door with the customer i have better things for my mine than clean a part which should have been cleaned to start with any way we all do what we wish to when it comes to jobs
I agree, but if they want to pay shop rate to clean their stuff, I'm not going to argue.
@@TopperMachineLLC well i say your right i hope they did pay you my experience what some say they do not necessary mean i have been burned before so now back out with them no matter if i get the job or not i am in different situation where i don't have over heads or a shop to so just do the work i know i can and no over loading still do some got to have it jobs but is nice to work at your own pace thanks for the videos there great i am playing catch up with them all weighting on the log saw Cheers
@@wallbawden5511 unfortunately, in my region, you have to take everything you can get to survive. But, he did pay. I wasn't happy about it, but work is work. What is so hard about going to the car wash with $5 and just clean it? In this case, it cost him good money. I'm hoping to have the big log up on Tuesday. But, had a good friend pass the other day and I'm not handling it well, so we will see.
@@TopperMachineLLC are Mate not good hurts like nothing else i feel for you and any others as people say to me time will heal they just did not say how much time any way stay safe and healthy Cheers the video will get done when it gets done no rush all best
Well when your the director producer camera man sound man and actor s--t happens.
If it's too dirty, turn the job down. If the customer is willing to pay you $100 an hour to clean it, then clean it.
He was turned down by 3 other shops. Mostly because nobody could do it. He didn't argue with the bill and said there would be more.
Yes, you should not have to do cleaning. That's for lesser hands to do. Seems a bit disrepectful of the customer to do so.
When it comes to really nasty stuff like that I take to the car wash, put on a rain suit and go to town.
Been there, done that. Usually when I buy a used machine, I pick a car wash a few towns away and get it good and clean. But with the temps we have been seeing, I didn't want to do that.
I would charge the customer whatever environmental disposal fee is associated with getting rid of that pile of dried grease. Or just box up the dried grease and give it back to them. Seriously. ----Doozer
Clean your stuff first!
Yes, I hate filthy jobs. A simple repair can ruin your day.
Nice job sir ! I've been planning on building a line boring system for the two boring mills at work and this helps with a few questions i had. And that new lathe must be real nice to operate. It looks like a solid machine. I know what you mean on the coolant issue. The shop i work at is an ISO 9000 and 14001 company, that means they only buy this "environmentally friendly" cutting and tapping fluid at $65 per jug and over time it eats away at anything plastic or rubber and it also becomes like tar if its left to sit on the table or ways. And yea it peels paint. We just cant get through to the higher-ups about these issues so we just live with it. Enough of my rant.....thanks for another great vid.
Cheers and stay safe.
