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. 👍🍌🇨🇦🕊️🇺🇦🤞

Threaded rod was not nearly rigid enough to support the pillow blocks, you can see them shaking.

[@Ujeb08]

not only shaking, they were wobbling probably 30 to 40 thou.and no doubt causing egg-shaped holes

[@CothranMike]

Only on the roughing passes, steady on the finish light passes. Works for me!

[@bcbloc02]

Look at all that free top soil!

[@fredflintstone8048]

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.

[@dikvandersar6267]

Compliments! Your workshop is very clean and organized. This inspires me to make my workshop cleaner.

[@donanything6816]

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.👍👍👍

[@TgWags69]

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.

[@TopperMachineLLC]

Wait for next week's video. 😉

[@billdoodson4232]

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.

[@bostedtap8399]

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

[@dermotkelly2971]

Another good job. Must take some time to set up those self-aligning bearings to the correct height.

[@mabmachine]

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.

[@TopperMachineLLC]

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.

[@jpsimon206]

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

[@jackdawg4579]

Nice work - did you lose any internal diameter when fitting those outer bushes?

[@TopperMachineLLC]

No,. They were bored to fit exactly. The bushings I made were heavy enough not to crush.

[@repalmore]

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.

[@TopperMachineLLC]

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.

[@martinnorbeck4657]

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.

[@TopperMachineLLC]

The customer got it back together without issue. But I would have liked to seen the finished assembly also. Thanks for subscribing.

[@MotosAndMachines]

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.

[@TopperMachineLLC]

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.

[@life.is.to.short1414]

How do you get your boring bar to be true.( straight or leveled)

[@powerhungrytoo]

What was the size difference between the cast bore and the steel sleeve?

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?

[@TopperMachineLLC]

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.

[@nschelling6420]

I believe the tractor part you are working on is known as a “bolster”. Looks like its off a CIH Magnum.

[@TopperMachineLLC]

It is. I think he said a 2390 or sometime like that.

[@MegaRiffraff]

👍🏻

[@docokd7oco443]

Good job. Yes, RN's are precious people and they do work hard. But, underpaid? No chance!

[@robjaimiehickford4559]

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.

[@hobtink]

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?

[@TopperMachineLLC]

part being machined was cast iron, not easily welded to.

[@araofmadisoncasey4247]

i like the split views

[@grosom31]

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.

[@TopperMachineLLC]

I just opened them up and then made the bushing to fit.

[@grosom31]

@@TopperMachineLLC that's what I was wondering did you make them both different diameters, or both the same?

[@lostvikinga]

How much bigger is the bushing you made than the bore to enable the use of Hot/Cold to fit thanks

[@TopperMachineLLC]

This one was about .003-.004 larger. I honestly don't remember, just based on size you go .002/inch of diameter

I worked in the maintenance department in a large truck factory , a dirty part taken to the machine shop was not touched !

[@paul5683]

Anyone who hasn't done any precision machining doesn't realize how dirt will affect the quality of the overall product.

[@GaisaSanktejo]

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

[@billryland6199]

The blue bearings needed side support to stabilize them.

[@georgeescaped6035]

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

[@jpsimon206]

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?

[@nschelling6420]

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.

[@johndebrular979]

It would be nice to have a tailstock.

[@joewhitney4097]

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.

[@TopperMachineLLC]

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.

[@donteeple6124]

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

[@TopperMachineLLC]

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.
