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

IT'S ON THE OWNER to fix the "repair" and not use it til failure. How many headaches could have been prevented by the owner being more engaged-BUT-it gives work to Mr. Topper-so thank you poor owner

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

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

What beautiful work of art! Thanks for sharing.

Saw your our warning about finger rings, we can’t wear jewelry at work. Had a coworker partially degloved his ring finger working around the house. The company was going to terminate his employment, half the employees threatened to walkout if they persecuted him in that way. Thanks for sharing.

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.

I really like josh's attutude when it comes to perfection

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.

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.

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

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

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

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!

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..

"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!

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.

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!

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! 🙂

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

Thank you sir! Enjoy this "analog" style work. Thank you

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

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

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...

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.

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.

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

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

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

4 ай бұрын

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.

@@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.

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

beautiful job, Josh! love old school work

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.

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...

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

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

Nice video. Pure machining, direct to the point.

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

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.

Gotta say the chipping characteristics of that material is really interesting. I've always heard that of stainless steel, but never really worked with stainless.

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?

Nicely done. Love your new lathe.

I really like you videos Jake. What a great way to justify what it takes to do these repairs!

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

Good Stuff JT

Very nice, very interesting.

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.

Good job 👍

The coupling you made looks more substantial anyway. Thanks for the video keep on keeping on.

Great video, Josh. Interesting techniques. The spade drill was impressively accurate.

Your version of the coupling is neater and better ! Have a great Sunday.

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.

You have a nice shop, and your work also looks very nice Josh. Owatonna made skid loaders for John Deere too. I have the model 70 with a 23.5 hp Onan engine, which my dad bought new in 1975 for the farm. It's a neat little loader that will get into places others can't and is surprisingly strong for its size. We used it for cleaning stalls in the dairy barns. I repowered it with a 25 hp Honda engine a few years ago which made a huge difference in reliability and power. It uses a double row chain coupling for the drive with one half being a 13 spline to the pumps, and the other half 1 1/8" keyed to the engine. The splines on the pump side were worn out and I could not source a new shaft, so I pulled the pump and disassembled it, built up the shaft, and cut the new splines on the Bridgeport. Had to make my own 60-degree cutter for the splines and because I didn't have a dividing head at the time, I made a 13-hole plate for my spindexer and used that. Been running now for about 500 hours with no issues at all. I can still get some parts from JD for it, and what I can't, I either make or source/adapt other parts to keep her going. I picked up an extremely nice original Brown & Sharpe 10" universal dividing head at auction a while back with all the manuals and tailstock for 150 bucks. I really use it more than I thought I would and have no regrets about getting it. With money getting tight, I'm starting to see quite a bit of welding and machine work through the door for things nobody used to fool with having done. Parts are getting scarce for a lot of equipment now, so I am reaping the benefits of the situation. I left a full-time job last year to work in my shop like you do. I have a 150 ft commute to work, and it feels wonderful to finally work for myself after 10 years of investing in the shop and equipment to start the business. No more corporate BS to put up with and no boss to blame for screw ups...only myself!

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 👍

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

Reach is always a problem for slitting saws. And the arbor is always in the way. Particularly I find the bottom section of the arbor to be a problem when slicing small work off of stock held in the vise. I've considered permanently mounting a few saws on dedicated arbors that have no nut on the bottom. That way I could have the saw run true so each tooth takes a bite and the diameter of the arbor is smaller. BTW, if your ring is stuck, use some soap a lubricant and hold your hand above your head so some fluid can drain.

Man, that intro was well thought out. Some jobs just don't have what it takes to make a great intro. I've spent so much time thinking about this exact subject. I'll keep trying. As for the ring, it usually sits with my non shop glasses on my desk. I get out here, fire up the computer and pull the ring and swap glasses.

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.
