Making Replacement Shaft and Coupling for an Obsolete Skid Steer Loader - Manual Machining

[@bernardwill7196]

Your customer get a better coupling than before. Nice to see a pro handle that. Greetings from Germany.

[@TalRohan]

This appears to be why the majority of people that do it, get into machining...specifically so they can make new bits for old machinery. Good stuff Josh thanks for sharing

[@walteraddie7925]

Love how the part turned out. I seen tons of woodruff keys used to hold hubs on to gear boxes. Worked great but rust was always an issue getting apart. The manufacturer's refused to put a dab of grease on before assembly which super annoyed me.

[@guyfranks4354]

Josh, have you considered a silicone wedding band? Several of the other machinist and mechanic channels that I watch wear them. You always have great contenr. Keep up the great work!

[@carlthor91]

Josh, new skid-steers are $100k+ these days, thankfully there are good machinists, like you around to help. Good non-obsolete ones are damned expensive as well. Best wishes from the far North.

[@ronfrance4041]

Love this content. My dream is to build a shop and have a lathe and mill some day.

[@stephenmeeks684]

Job shops are a good way to keep old equipment running. Good work on the parts.

[@MrFHLH]

Interesting job, excellent work Josh as always, I'm sure the customer will be delighted with.

[@LaLaLand.Germany]

Yes, we can´t save ´em all but we shure can try. I just love it when machinists take some pity and re make something so the old chunk of steel can get a second life. I´m shure the owner WILL take good care of the machine, thanks to You. -Another German

[@mikep1085]

Great job! Its always interesting to see the sequence of how you are going to machine something.

[@alfredsamperi9776]

Nice job, Josh! Regarding “touching off”, I can understand that the cutter has to be spinning so that the measuring system can accurately zero the cutter. But wouldn’t the spinning cutter inadvertently cut into the workpiece, resulting in a false zero?

[@kentuckytrapper780]

Great video Josh, I worked in a coal mines for 30 years and got into the machine shop biss so I got my wedding ring tattooed on,lol much safer..

[@geoffflato2094]

Great work as usual. Also can't emphasize enough how dangerous long stringy chips are. Probably 3-4 years ago I cut my middle finger most of the way off with one or those chips on 4140ht. A moment of not thinking was all it took. Got it pieced back together at the hospital and have use of it, but have no feeling at all beyond the cut line.

[@passenger6735]

Sounded like someone shot the previous repairer at 3:20.

[@KW-ei3pi]

Beautiful parts, Josh. They are no doubt the nicest parts on the old Skid Steer!

[@bostedtap8399]

Ouch, the original bodge up looked painful 😢. Great design and Improvement Josh. Thanks for sharing

[@bcbloc02]

The ones that welded it up and just clamped it obviously thought the machine was heading for scrap or at least I hope that was their excuse!

[@TopperMachineLLC]

My guess is they "fixed" it just to sell it. Let someone else deal with it.

[@cezao93]

Nice video. Pure machining, direct to the point.

[@kkoch666]

I dont know anything about this stuff, but why did that first milling pass sound so bad? Or is that normal?

[@The_DuMont_Network]

You mean you haven't yet machined a quick release for your ring? . Always great to see another Topper video. Hint: It's time for another railroad themed article...

[@TopperMachineLLC]

Unfortunately, there will be almost no more railroad videos. I was threatened by the FRA with fines for that they saw in the videos. It's not worth a $10K fine.

[@PioneerRifleCompany]

You have a good example, here, of when to be precise and when tight tolerances are not so important. Great job!

To get your ring off wrapping the finger with dental floss works.

i ran into a similar issue and kept breaking (cheap) slitting saws. i ended up using a cutting disc on a custom mandrel! it worked though and was pretty damned accurate.

[@PLUSHAIRPLANECARPET]

you're doing a great job showing the versatility of a lathe and bridgeport combo.. good job

[@MrKotBonifacy]

The safest design for a swarf hook is "foil sword like" fashion - a large wooden handle (like one used for big files) which gives you a good, safe and secure (and comfortable) grip and there's no way you could put a finger "into it", neither unintentionally/ by accident nor on purpose - and when it gets accidentally yanked forcefully from your hand there are no narrow edges to do much harm to your skin and bones. Then there's a "hemispheric" steel hand guard (doesn't have to be a full hemisphere) followed by a not too long "blade" (obviously), ending in a poker-like hook - which allows you to both pull the swarf and push it away if needed.

[@robrobitaille4235]

As usual, I learned a lot. Thank you for the great content. As a hobby machinist, I enjoy learning techniques from the experts.

[@bobhudson6659]

Well done. Re wobble never had any luck running slitting saw perfectly concentric despite the best of set up. Also seen same issue with Keith Fenner and Adam Booth who know a good bit more than me.

[@theessexhunter1305]

Top Darts Josh, I like the re-work on the lugs very neat.

[@fredhoyt6900]

For a Machine Repair Machinist that apprenticed starting in 1974, watching you work is a pleasure. My question is since the two pieces of the coupling locate on the shaft when installed, how could the bore be egg shaped , physics and all?

[@TopperMachineLLC]

I'm guessing it worked loose at one point. Someone repaired it by building up the inside with weld. It was truly ugly. It was probably out of alignment after that and chewed the crap out of all of it. It was the worst mess I've seen in a long time. Had they not already been thousands of dollars into it before finding this, I would have told them to scrap the machine. Actually I did tell them to scrap the machine.

[@fredhoyt6900]

@@TopperMachineLLC My comment was inre: to the comment asking if your new part would have an egg shaped bore due to being split. That would only happen if it was clamped togather without the shaft. That is not the case. The new part could also be made of two pieces of stock, tacked together seperated by a shim. Bore, tap drill, clearance drill, tap and ream. Grind off the tacks, remove the shim now in two pieces, bolt the coupling halves on the shaft. turn assembly as needed for clearance.

[@juhu34]

Have some dental floss on hand in the shop to get the ring of, just thread it under the ring and then wrap it around the finger over the knuckle then unravel the inside end of the thread and the ring will creep up of the finger. There are nice demonstrations on youtube 👍

[@BruceBoschek]

Gorgeous coupling. My first thought was, "How is Josh going to split that baby?" Using the band saw didn't come to mind, but since you already had the slit it made sense. Thanks for another scintillating video! 🙂

[@johnnyholland8765]

Great job. I like making old worn out stuff new again. You know I have never ran a slotting saw that didn't have a loping out of round sound to it when it was cutting. Even using a new arbor. That will probably be the newest best looking part on the machine...

[@joewithrow2345]

beautiful job, Josh! love old school work

[@StuartsShed]

I just totally enjoy seeing a decent cut peel material away and leave that finish. Never gets old. 👍

What beautiful work of art! Thanks for sharing.

[@jimwednt1229]

I'm always happy to learn something new about subjects and things that i had pretty much all figured out. There's always more to learn! It's so cool that you can make anything, any part or tool you need in your machine shop.

[@ThePottingShedWorkshop]

"Parts are not always available". Yup, thats why I have my little machine shop at the bottom of my garden! Good video. I cringed as the slitting saw did its work. I've had bad experiences of them loading up, binding... BANG!

[@terencesullivan7788]

Hi just started watching your videos iam a retired engineer of 50yrs nice to see proper skills still being used

[@quantumss]

Don't understand why the price of a machined part isn't stated. As if it's a secret-------------- don't ask. Bull, I'm asking.

[@bazookamoose7224]

I’ve had to modify slitting arbors to get the extra distance needed too. No one makes good slitting saws any more! You could always try to chill the hand first, apply some olive oil around the ring, then in a boiling water pot heat up a big heavy spoon, then apply that spoon tip to the ring and see if you can get it to expand enough to slip off. Good luck Mr. Topper!

[@TheUncleRuckus]

Looks great Josh, it'll last longer than the skid-steer its going on will lol. Thank you for uploading! 👍👍

[@TopperMachineLLC]

I'm honestly surprised the skid steer lasted this long. It's an old owatanna mustang. Those things were junk when new.

[@kurtg5645]

So, what should I do to add the flying handle feature to my drill press？

[@TopperMachineLLC]

Get a crappy cheap Chinese drill press. LOL

[@zmotorsports62]

Great video. I'm sorry if you mentioned this but I went back and looked again but couldn't see what materials that you used for the coupling and the shaft. All you mentioned for the coupling was that the original was cast and you were using 2-3/4 round stock. Is it just 1020 mild steel or did you use something different? Thanks. Mike

Circular saw blades do a surprisingly good job as slitting saws. Get one with a thicker kerf, and fewer teeth than you would for wood, and you're good to go. There are lots of size options in the 3-5" range now.

I'm old school, everything is repairable now more than ever! If its metal there are scanners and CNC machines that can replicate the part. If its plastic you can use your cellphone to capture images and create a 3D print plan that goes direct to the 3D Printer. If its computer controlled, you can get a Raspberry Pi to emulate the old computer. The biggest issues I see? Companies screaming IP Rights and attacking you because you want to keep your property running.

[@bigmikex2333]

Great content!! Don't square keys carry more load? Is that why Woodruf keys have faded?

[@notajp]

I recognize that part! I have a 70’s OMC Mustang 1000 skid loader that used that setup. That uses a two piece drive shaft that runs to the drive sprockets in the side housings. They used a belt driven variable drive system like a snowmobile with the driven sheave on the two piece shaft. The drive sheave on the engine is opened and closed hydraulically to vary the speed. The shaft is made as two pieces with the coupler so that you can replace the drive belt. Mine was missing the original Wisconsin V4 engine, as well as many of the variable drive parts, including half of that coupler. I ended up repowering with a 24 hp Onan engine, replaced the two piece shaft with a one piece shaft and just used a chain drive single speed system.

[@xenaguy01]

31:20 Rather than purchasing a new 0.045 slitting saw for one job, I'd have split it with a bandsaw, which it turns out you had to do anyway. Then faced each side in the mill (or sander, as you did). Would have saved two days on delivery, and saved the cost of the new tool, which you may very well never use again. 36.51 Even if he put $6,000-$8,000 into parts, he probably saved a lot. A new skidsteer costs anywhere from $10,000 to $80,000.

[@TopperMachineLLC]

I ordered it because I actually have several parts of my own to make that will justify the cutters.

[@xenaguy01]

@@TopperMachineLLC 👍 That's different.

[@BrucePierson]

I'm sure I have something that has a woodruff key, but I can't remember what it is, likely one of my old lawn mowers or chainsaws. Not something you see very often, it's mostly just a regular key-way these days

[@twotone3070]

Out of curiosity, why did you do the last drilling operation on something I thought you had threaded?

[@bobmazzi7435]

That was to remove the thread in the top half of the coupling. It needed the thread in the bottom half, but with the split, the top half actually would be a problem.

Hi there, great video. Im just learning machining and found your video very informative. Quick question - after slitting would the bore of the coupling drop out of round? I was e pecting you to somehow rebore it. Thanks

The bore does not change shape, it is still round. It just has a small gap allowing for tighter clamping.

[@colinhamilton9714]

@@TopperMachineLLC Of course, thanks for getting back to me.

[@Buddha-of8fk]

@@MICHAEL-ys3pu Basically means Journeyman Tool and Die Makers have to go through classes like trig, geometry, drafting etc. at the same time we go through the apprentice program where we have certain amount of hours on each machine. Lathe, horizontal and vertical mill, surface grinder, ram and wire EDM. I don't think it's done anymore like that here. Pretty much everyone specializes on one machine. We did it different in the stone age.

@@Buddha-of8fk ok thanks mate, I think a Tool maker and a Die maker are two separate apprenticeship here.

[@Buddha-of8fk]

@@MICHAEL-ys3pu A vertical mill would be the most important. Definitely the most versatile machine. Lathe then surface grinder. Last would be a ram EDM and you can do all kinds of things. It's amazing to take a piece of metal and make something out of it.

[@victimovtalent6036]

sir,why so many machine parts/body made of cast iron?

[@TopperMachineLLC]

Cast steel. Cast iron would never hold up in an application like this.

[@weirddeere]

Casting a part is much faster and cheaper in a manufacturing sense, when you go for larger quantities.

[@buckinthetree1233]

​@TopperMachineLLC, the coupler was made of cast so that it would wear out before the shaft. I'm not sure in this particular application, but usually a shaft coming out of a gear box or motor is more expensive and labor intensive to replace. In this particular case, when someone went in and put a hard weld surface inside the cast coupler, it caused it to eat up the shaft. They will also use cast in order to create a weak link to break before you twist off a shaft. Judging by the looks, I'm sure the part you made will be the last functional part on this machine.

[@TopperMachineLLC]

@@buckinthetree1233 the original part was cast, correct. But it was cast steel, not cast iron. Cast steel will last just as long as plain steel. Cast iron would never be used in a power transmission coupling as it would fail rapidly and possibly explosively. Based on what I know of this particular skid steer, I can guarantee my coupling and shaft will outlive the machine.

[@buckinthetree1233]

@TopperMachineLLC I'm not sure why you were tagged in my reply. I was trying to address the original question. I could tell what kind of shape the machine was in by what the previous owner considered an acceptable repair. When a machine owner performs half @$$ repairs, they usually perform half @$$ maintenance.
