How To Repair A Worn Hay Baler Part: Manual Machining Explained

[@TopperMachineLLC]

[@Invinciblemoam]

It’s always best to heat the whole part in a something like an oven rather than localised heating. When heating with a torch the expanded material close the centre has nowhere to go since the outside of the part is still relatively cool this can sometimes make the bore smaller!. In this case it was the underside that must have had a heat induced taper. I love your videos and never see you make a mistake without explaining your reasons for/against afterwards. I work for a UK based engineering company with 14 years tool based experience, just passing on some knowledge an old timer kindly/angrily gave to me

[@DouglasRees-c6j]

True. Judgement is used as to how best heat it. Cracking on cool down is a big issue with localized heating of hubs with spokes. (Not applicable to this repair) Really old flywheels had curved spokes to address the cool down issue before they figured out how to make the straight spoke castings cool after casting without cracking a spoke. I have lost a few spoked pulleys by only heating the hub. They make a loud bang when they crack a spoke during cooling.

[@july8xx]

We have an older Ken more self cleaning wall oven. On really difficult pieces we can leave it in over night and freeze the pin the next morning. Press it in and put it back in the turned off oven and let it cool down in there.

[@150flyer4]

The method I normally use is to get frozen to the pin, get burned by the casting, jamb up the press, and then knock the whole setup on the floor. Good finish on yours!!

[@TopperMachineLLC]

Lol, fun fun.

[@kd5byb]

HAHAHAHA that sounds like my method too! 😝

[@RobbyRutherford]

If you're not hurt or bleeding are you really fixing anything?

[@july8xx]

Been there done that.

Watching shrink fits gives me the hives. That moment when it suddenly won't budge any further and I fall off my chair. Glad it worked well, Josh. Good repair, as always.

[@TopperMachineLLC]

Always scary.

In my shop we have a freezer that is -100°. It's made for the medical field. I also found out when press fitting you cool or heat one side not both. It tends to fight each other when heat and cool.

As someone who owns an old baler, I liked this one.

[@TopperMachineLLC]

Check your grease lines. Common problem on these.

[@jacquespoirier9071]

be able to bring back in service an obsolete piece of machinery is priceless. excellent job 3 thou interference on a such small diameter is in fact a tight shrink fit so it needs a dry ice cooled pin in a 500 degree F bore, I had to a very similar assembly and to my experience, it is a good idea to increase as much as possible the bore temperature to gain a bit of lattitude in the assembly process. excellent video

[@noimagination99]

Hi Josh, Twin Sticks renovates old American trucks, I referenced him because of the beer comment you made, Kurtis however is a very good Aussie machinist and well worth a watch.

[@TopperMachineLLC]

I had to quit watching Kurtis. Between the theatrics and sloppy workmanship I was seeing, I just can't respect him anymore. I'm happy for his success, but he is not as good as everyone thinks. If you want great Australian machinists, max Grant of the Swan Valley Machine Shop, and Matty's Workshop are both highly skilled and do amazing work. No theatrics, no sloppy work, just real good machinists.

[@alanm3438]

Thanks for the video. I know it takes extra effort to make the video while working. I am not a machinist, so watching your videos is like the first day of school for me. I know that there are different kinds and grades of steel but I do not know how to determine what it is unless it has a tag. I am glad that the shrink fit worked out. I sure do admire your skill. I am glad that you were able to help this guy and save him some money. It is always good to see you. I hope Rocky is doing good.

[@TopperMachineLLC]

Thanks. The customer was super happy.

[@BrucePierson]

It's always good to be able to repair expensive parts and save customers a fortune as opposed to them buying a new part. It also works when the part is no longer available, as it saves an old machine so they don't have to spend an even bigger fortune to replace an expensive machine.

[@StuartsShed]

That went great actually. I thought 3 thou was a pretty heavy interference when you were talking through the parts - but the beauty is that it isn’t ever coming out of there. Handy to have the press close by. ✌️👍 We did a similar one at work and unfortunately got stuck half way. The bastage wasn’t going in or out, so we had to start over and machine the pin out. Bummer.

[@TopperMachineLLC]

Ive had that happen before. Makes for a terrible day.

[@acmemachining]

Great job keeping the farmers farming. It is a shame how quickly parts become obsolete, but a win for us. Thanks for sharing. I use my co-axial indicator the same way. manually turning speed, just nice not to be jumping behind the mill to read regular indicators.

[@scpvrr]

Well done Josh. Every machinist that I watch has a “Whew!” moment when the interference fit is done. Good to see your preparation and urgency for the s*** moment. Good job bringing us along in the moment.

[@TopperMachineLLC]

Thanks for watching

[@terryfromsouthcarolina4601]

At the plant i worked at we did a LOT of shrink fit repairs. They were all nail biters. Some went wrong. That sucked because production was down on that machine. I have had a pin like that upon cooling crack the bore. That sucked. It was a big repair. I dont drink but i almost started that day. I was the shop supervisor and ALL eyes were on me. I'm glad I'm retired.....LOL! Cheers Terry

[@DarkWolf958]

nice unintentional wave effect with combined rolling shutter and vibration.

[@TopperMachineLLC]

I've never had one do that before. Actually aggravating when I saw it.

[@richtes]

What technically caused that? Was it the frequency of the vibration with the slitting saw?

[@dalebailey1844]

I love the fact that you could put your hands anywhere you want and not worry about getting cut by fillings. IE you keep it clean there.

[@greglaroche1753]

Being able to make your own dry ice is nifty. Thanks for the video.

[@johnsullivan7633]

Well, from this video, I learnt to be prepared for the worst when doing a shrink fit. When I have my next one to do, I think I’ll set it up in the press, just in case. Thanks for the lesson.

[@TopperMachineLLC]

This one was exceptionally tight. Usually no more than 0.002/inch of diameter. I was just over that. Never want it to move.

[@ellieprice363]

I’ve had that same problem with press and shrink fits. Often the problem is not enough heat. I’ve almost switched completely to Loctite retaining compound now. Glad you got that sucker in there.

[@e.scottdaugherty8291]

Yeah, good idea.

[@orangetruckman]

I learned to have a chaser after a press fit job 🍻

[@jlippencott1]

Those coax indicators are a pain to use. I always use the good old edge finder to find center. It works better and easier. Most people don’t know this, but it will find the edges of holes and pins just as accurately as it does linear edges. I use it all the time to find center by zeroing one side of the circular feature and the distance to the opposite side, then splitting the difference. It’s much easier if you have a DRO.

[@Dogfather66227]

I enjoyed watching this repair. My best experience with a precision shrink fit was on the cutter head for an asphalt milling machine. It was 3-15/16 dia. And about 5” long. The interference was 5-1/2 thou so I specified dry ice and heat to 300 deg. F. Because of the bore length we set the parts up in a 30-ton press just in case, which turned out to be good thinking. There was definitely a bit of pucker factor as temperatures try to equalize quickly. Those dry ice fits sometimes make interesting sounds when seating. Thanks for sharing this one.

[@TopperMachineLLC]

I used to do some similar sized ones. Since LN2 is not readily available here,dry ice is the best bet. We always went to 400° for safety. Needed the press one time.

[@carlzwanzig5372]

Big thing about using dry ice vs LN2 is -109 degree F vs -320 degree F, you only get about one-third of the shrink; gotta keep that in mind. With LN2, the part probably would have dropped right in (at the expense of 2 hours driving to get the stuff). Anyway, nice job there, it's always interesting to see how people approach a problem and get it done.

[@TopperMachineLLC]

It would have been 2 hours of driving for dry ice, that is why I make it. LN2 would be 3-4 hours of drive time, making that unacceptable. I can't bill for time and materials to get supplies for a simple job. I wish I could get LN2, it just can't happen here, too depressed of a region.

[@holdilocks]

I would start by setting the boring head on a piece of sacrificial material before setting up the part to machine, it may need a little tweaking per the tool pressure vs different material, but it can save a little chatter or taper.

[@rexmyers991]

Just a note about sawing off the pin with a slitting saw, slitting saws are pricey but my favorite alternative nowadays is the 8 inch carbide tip blades they sell for metal cutting skilsaw type saws. They are cheap like 40 bucks and less kerf, I have one on an R8 arbor I use all the time for cutting down pieces too short to hold in the bandsaw, slotting, or even have used it in the angle head for cutting plate clamped down to the table. Works great and in 4 years now I am still on the first saw blade of the 2 pack I bought!

[@LLAHTI1]

One beer?? For that save, at least a six pack!! lol

[@rupunzel6299]

That was a high stress moment... averted.. Better to set up the press-shrink fit in the press with the press ready to press before heating the part while the stud is cooling off in dry ice. If the stud is even a tiny bit off axis even with a few thousands of clearance the stud will likely get stuck on the way down the hole. More often than not, the press I needed to avert a Oooops and not fun at ll re-do.. There is a tendency for metal to stick when they are close together, this is why clearance alone is not enough. Some means of mechanical aid (force) is often needed to over come this tendency for separate metal parts to wanna cling together.

[@warrenjones744]

Regardless, that design of boring/facing head is pretty cool. I has to be more rigid than the typical R-8 style head being clamped to the quill like that. Probably an indicator to move the tool out on the final cuts would make it pretty accurate. I don't recall ever seeing one like that used on a bridgey. Cool. Nice ice maker! And great repair....Beer is good! cheers 🍻

Reminded me of my school days when I was a teenager in the 1960s - we made dry ice that way in physics lessons.

[@neffk]

"Let's see if we can do it in one shot" Wouldn't the balanced-cut method be less risky? Split the difference and take it in 2 cuts, about half. Tweak the 2nd cut based on the results from the 1st cut. It would take some of the uncertainty out of the process, whether from the boring/facing head, deflection, or shop gremlins. Same for the shaft, when you had 0.008 to go. Instead of taking 7 and 1, cut 3.5 and re-measure. If you're off by 2 10ths, correcting the final cut from 3.5 to 3.3 thou is much more likely to work because deflection and other factors are almost constant. Anyway, thanks for the video.

[@TopperMachineLLC]

In my experience it never works that way. Depending on size and material, I know roughly what to plan for cuts. Generally, anything under 0.020 is not accurate due to tool pressure. Also, shallow cuts leave bad surface finishes

[@richardsurber8226]

I enjoyed watching you work thru some problems

[@davewilson9924]

Wow! great work, but it's still just a danged old baler. On our farm we would have welded up the worn shaft with 7018, take the hand grinder to smooth it up, measure as you go then take the file to touch it up and bolt the stupid thing together!

[@ccrider5398]

I'm always amazed at how much replacement parts cost. I did some work for a shop that made replacement parts for diesel engines and the owner said "if you had to build a new engine with all genuine replacement parts you could pay off the national debt." I appreciate you sharing the prices of OEM parts and it shows how important what you do is to the small business man (aka farmer).

I never had a use for the coaxial indicators as I can do it faster with an indicol and interapid. But when I bought a cnc lathe they do work great for aligning drills. Also the slitting saw I wouldn't have thought of. I would have just used a couple drills to remove that. But that saw was fast.

[@badger305]

I would have beveled the pin on the back side and welded it also. It's because of the continual forces on the side of the pin that sticks out with the crank arm.

[@thatsthewayitgoes9]

I would’ve centered original pin. Drilled hole through. Take piece to big vise and hacksaw old pin off. Then setup using centered hole, drill & bore / ream or whatever you want to do. The new pin I’d make , I’d highly consider designing it to be Silver Bazed on. Or weld, not sure , I’m not there and not attuned to application of that crank wheel.

An old trick when installing a shrink fitted shaft is to put a lite coating of high temperature grease on the shaft. It slows down the heat transfer and buys you more time.
