Lathe Clutch Shaft Repair Part 1

[@gibbogle]

I'm not a machinist, but I find this fascinating and impressive.

[@kyleblann]

I sure do

[@BruceBoschek]

I did my PhD work and first years of graduate research at the Max-Planck Institute for Biological Cybernetics in Tübingen. I lived right next to the Walter-Tools work and had a friend who was an engineer in the turning-tools department. Their tooling is famous world-wide. Glad to see you using their carbide inserts.

Outstanding work, as always, your weld build up was fantastic 👍👍👍 I’m a marine engineer and had to turn and machine few parts love to watch theses projects. Amazing work Adam

[@johnbonner922]

Abby - thank you for the filter on the welding. Much appreciated

[@cleanmachine08]

Thank you for the very interesting and informative video. It also makes me happy to see someone wearing safety glasses under their welding helmet. I learned the hard way.

[@nicolaspillot5789]

@shocking development Newbie question here , what is the point ? second question, as i wear prescription classes, how could i stack them under the hood ?

[@cleanmachine08]

@@nicolaspillot5789 I wear prescription glasses too. Prescription safety glasses are available, and so are styles that can be worn over normal glasses. Personally I usually just keep a new, unscratched pair of snug fitting safety glasses set aside for welding, and I can see well enough except for some TIG. The reason for glasses irrespective of welding process is to protect from arc flash and back reflections. The glasses with correct rating can be completely clear, but cut UV to almost zero. Depending on the welding process, it is also not uncommon to end up with stray sparks or spatter inside a helmet, so glasses protect from that. MMA, MIG/MAG and even TIG weld beads often eject slag and deposits as a weld cools. Keeping eyes covered is the way to go when checking out a weld. Lots of KZbin's welding with no gloves, white shortsleeve t-shirt and staring at their weld beads with no eye protection. I am mystified by this.

[@matthewperlman3356]

I'm really impressed with the finish on that for tuning on MIG weld build up. It show just how solid your welds really are!

[@fathernojoy2706]

How many of us subs of Adam enjoy watching the set up more than the actual repair? The fun part of the fix is the work but the set up for me is my favorite part of the vids. It’s a puzzle you have to work though before you can start moving metal. I have a tremendous appreciation for this trade and what it takes to be a journeyman.

[@simcoespring]

Absolutely enjoying these rebuild videos with weld buildup, spray weld buildup, using a turning table for clean weld buildup. Being able to see each setup that you do is pretty awesome. I just bought some new tooling so I can do consistent block manufacturing. Bought a new clamp and some fixture plates. I can't wait to use them. Thanks for all the great content.

[@scatart]

I LOVE Walter tooling. Amazing as they heat up they get even tougher! Definitely run without coolant.

[@TheUncleRuckus]

@11:12 Adam, if you're having issues with your safety glasses fogging up, clean the lenses with some regular ole Shaving Cream/Foam. Just rub it all over the lenses until they're coated, then wipe it all off with a Dry cloth and the lenses won't fog up on you. It works great, my Grandfather showed me this trick like 30 years ago and I've using it on all my glasses, bathroom mirrors and the interior of my car windows ever since. Alternatively you can also use Liquid Dish Soap without water and it will do the same thing, it's just a little more fiddly to get a streak free finish. Give it a try I guarantee you won't be disappointed! 👍👍

[@Abom79]

Thanks for the tip, I’ll give that a try 👍🏻

ULINE REHAWK S-14171C we did a test at our company of over 100 different safety glasses and these allow enough airflow to not fog when you are bending over working, out of 100 guys close to 80 picked these great work my dude

[@randynewtonsr9659]

Another high quality Abom79 repair 👍😊 I for one absolutely love your channel and videos Adam 👍👍and To all the “ armchair know it all machinists” I pose a question to you , did you see any “ bluing “ or color changes on the shaft anywhere other then where Adam welded it ? No you didn’t , so the rest of the shaft will be just fine . Clearly the man knows WTH he’s doing as he has years and years of experience and oh , not to mention he is a third Gen machinist , so there SMH 🤦🏻‍♂️

[@shawnmrfixitlee6478]

Awesome job Adam , Proves you don't need to make new parts every time .. That's what job machine shops are for .. SO ENJOYED !!

[@oldschoolmobile]

Those Walter Tigertec are pretty good inserts. I also like Iscar and Sandvik for turning as well. For basic roughing or medium turning, Mitsubishi and Sumitomo are very cost effective options for a manual machine too. Just passing it along 😊

[@swanvalleymachineshop]

[@captainover-tighten6729]

I have to say the film work (while it had always been great) is even better. The closeups (as in the clutch shaft pt 2) were super explicit. Abbey does some great work and zooms in with her Carhart green welly boots (steel toe, no doubt). Thanks, guys!

This is bad ass, what a great way to fix a clapped out old shaft. I like the spray weld build up but to my mind this has to be a stronger way to build up.

[@paulcopeland9035]

He has to cut a key way so weld build was necessary. The opposite end takes a bearing and can be spray welded. All it has to do is fit the inner bearing race.

Intresting content, and I liked the close up photos at the end.

[@Thomas_Bampton]

good repair, i do a lot of weld build up repairs at work on big Liebherr 996 hydraulic pistons (internal rod to piston seals), good practice to pre-machine the area to be repaired under the finished size 1.0 mm to 1.5 mm per side so your under the fusion zone and clean any embedded dirt and grime off the surface so it doesn't become a inclusion or bubble in the weld. that would help a lot with the surface finish. also for the new shop, digital micrometers are really nice and can switch between inch and metric. the Insize brand are fairly good but quantum mics from Mitutoyo are stunning. you get what you pay for though.

[@ADOTlied]

Amazing, you have so much skill at this stuff, really well done.

[@franksherryt4500]

Great repair Adam. One thing that has helped me after 30 years of welding is getting a PAPR welding hood. While expensive, it keeps me from breathing welding fumes and keeps me glasses fog free. A word to the wise, stay away from good Mexican food the day before.

[@littlejackalo5326]

$2000 for a product he'll use for an hour a month. Not viable.

[@johnbonner922]

Or bad Mexican refried beans within 24 hours before. XD Does a fan help as a much less expensive option if the hood is not feasible? Or does that present complications?

[@TheTrashologist]

@@johnbonner922 depends how strong or close the fan is, if you are using gases they can be blown away. But I use a fan sometimes especially when welding inside a truck just to blow out the fumes and keep the air moving.

[@mfc4591]

When I did my training all those years ago, we had machines that were 'inch' which came from England or the USA. Then we had Japanese and European stuff that was metric, so I understand both. BUT (never start a sentence with but!) metric is so easy and just as accurate.

[@Matthew_Lloyd]

[@harlech2]

Verry well done, Adam!

[@garymucher4082]

I was wondering if you were to have turned the shaft down some before welding it up, if that would have given you a thicker final finish. Since the new weld is merely a few thousands, is that okay and work good... IDK

[@nils1953]

That's true but unlike a spray weld I don't think a mig weld is ever going to peel off since you have much more penetration and especially fusion because the base metal his heated and mixed a lot more. So while he didn't remove anything, because a weld bead is so much more energy dense, I think it should be perfectly fine as is.

[@markshort9098]

Mig bites in enough that it ain't coming off.. the advantage of turning it down first is that all the metal is the same hardness so tool pressure remains the same and it eliminates thicker spots where the material is harder.. it didn't look like it was a problem with this repair but it's a problem I've run into before

Start by welding from the end so you have built up heat when you get inside the end of the groove

[@oleran4569]

Cool! Lathe work to make a lathe work.

[@neiljones8269]

I use a bore welder and the welding machine settings are quite different to allow upside down welding, a major benefit is reduced heat. Low volts. Drip transfer welding. Needs to be laid over a machined surface.

[@r2db]

11:12 I really like my 3M Adflo respirator with Speedglas helmet to prevent my glasses from fogging up. It also keeps me from inhaling all sorts of nasty things, as I seem to spend more time grinding than welding. The joys of being a rookie, I guess.

[@Freetheworldnow]

As it is possible to do so, I would turn down the diameter of the damaged portion by about .020'' on the diameter prior to welding. As after dimensioning, your (weld) root does not get anywhere near the surface as if you do a straight weld up. Hence, I will assume to achieve superior bonding and metal integrity.

[@brosselot1]

[@ypaulbrown]

hoping you get to use the Starrett feeller gauges...cheers from Orlando, Paul

[@1956Taz]

Adam I always love watching your videos but I'm going to put my cheap two cents in here. I worked on six different monarchs double e up to 28 in by 12 ft lathe. Anytime I had a repair like that and a certain length of shaft, I would chuck it either in the three or four jaw, Chucked on the tail opposite end of that shaft and then put it in steady rest on that what looks like a bearing journal the area that you did not weld. Then Center the shaft because you could have cross actual condition going on when you chucked it short like that. That's very important. I'm always worried about something like that. I hope it comes out good but I would have done it the way I mentioned. Have a great one!

[@boydhorning1830]

Yes, good observation...I'd do it that way too.

[@ALAPINO]

Pardon my ignorance, Ladies and Gents: Would machining the welded build up be possible/advisable using a HSS tool? (Or would the welded build-up pose issues with the cutting tool) Cheers!

[@firstmkb]

Try it, and let us know?

[@dlfabrications]

Just a thought, if your MiG welder was connected to a lead screw 4-5 TPI and then connected to the chuck with a belt, you would be able to vary the feed rate of the weld by varying the speed of the welding fixture in the video. Maybe bit much maybe? maybe not? Great video❗👍
