I love that SO much resources get expended in trying to restore these relics. Almost every time, Beau and the rest of the crew achieve almost incredible restorations, and if not, they pre-age some one-off replacements - like the return rollers - to obtain maximum miracle results. But sometimes, you just can't pull a miracle out of the shiny top hat. This will, I know, only slow you down some, because I know that you Champs won't let it beat you. Another great video, guys.
As always, great work Beau and I'm glad you're feeling better again, plus my compliments to the entire team for producing another, fine episode documenting how much love and attention you lavish on these old girls.
I've been binge watching the first thirteen episodes of this playlist on one evening and I enjoyed every second of it. I've got a 1/35th "StuG III Ausf. F last production" in my stash and I will come back to watch matching episodes when I start building the kit. I can't imagine any better reference than your vids, mates. This will help me a lot and when I look at the fiddly parts in the kit's box I wish I could work on an original StuG. I doubt I'd have the patience for the work you did on the gear box, but I'd love to work on a real vehicle and see the progress. Thank you so much for the uploads.
these guys are backyard butchers,they have no idea and destroying historical parts, they say because its to hard, or not enough time as an excuse, we would rebuild and repair vintage gearboxes from just drawings, even the housing, shafts splines, gears cut, key ways ect, how can they be allowed to destroy history , beggars belief
The dedication to restoration is amazing. When it would be so much easier just get new parts manufactured the team goes to great lengths to salvage the originals, not matter the condition. Admirable stuff.
A word about the classical background music.....I love it! It's a refreshing and relaxing change from the previous guitar-banging stuff. We are talking ASMR tank restoration! And Dvorak is an excellent choice. I'm partial to Rachmaninov, but anything will do. Thank you!
Another great episode as always fellas, the filming, editing and sound mixing are all getting better and better each week. Beau looked a bit like death warmed up by the end there, hope he's alright. Also loved the cheeky famous last words...
Sorry Beau, you went above and beyond when the transmission was beyond repair. A double spline is a killer. Lucky that it was large toothed. At least you can build your own end on the gear. Good to hear you are fully recovered. Great work, stay safe and well mate.
awesome job beau, i worked at a railroad and we had a turntable apron with a big torsion bar we determined it to be archeologicaly welded. it ton 110 tons to push it out, and a sledgehammer a 2x4 and lits of antiseeze. keep up the awesome videos
This effort paralleled mine removing the yoke from the driveshaft on a 1961 Corvair Rampside. I did not have acetylene heat only my Bernz-O Matic, a gear puller and several hammers. Took me 8 hours spread over 2 days Hock.
Nice work, you’ve got what you needed !! Just a little tip, in the future, try to heat the gear, not the axle… doing so, the gear will expand and get free.
As always, totally inspiring stuff. I can see that it's hard work, but keep going. You're an inspiration, and your efforts to preserve are not missed by this archaeologist - after all, attention to detail is everything 😉
Beau: "The last thing you want to do is cut into your shaft". I'll bet the laughter of Beau and cameraman which followed that line was a welcome tension-breaker.
Love the engineering drawings, more of those please! And if possible links to larger copies? I find these really fascinating and would love to study them!
You need to start with the schematics. Poking around a 70 year old gearbox blindly is,not the best aporoach. That gear could have had a lock tab on the other side, or a special keyway which was pressed on using way more pressure than that anemic puller. You got there in the end, though...
Great video guys thanks! That output gear is a marvel of engineering just by itself! I hope enough detail is left that youse can have another one made. The new one is gonna be an absolute jewel.
Great episode! sorry this is Tony not Kathy. , but I had to laugh. I tried taking out a tree stump with my sons the other day. Let’s just say that hacked up stump is covered in dirt. I love the determination, and can feel your pain … my favorite part was the perfect screws . Please keep it up, I love your channel . One of these days we would love to see the museum … Tony
I can see the Hard work going into it Beau . I congratulate your work. I had done "my boiler " trying to repair under frustrating circumstances . Sometimes under a heat wave . Have a walk / break to think about what to do if gets up ya goat is my tip
First off, you guys are amazing. I am truly inspired by your skills and tenacity. Beau is really a master fabricator. Just a suggestion but you guys need a penetrating oil called Kroil. It works wonders. it would probably cut hours of work time. I have used is for years and it really outworks any of the other available products. No, I am not paid to endorse it. I just do restorations myself.
Absolutely insane how well those bolts came out of the locking nut there w/ the wire tied around it. well down in craftsmanship my ancestors. P.s i hope Beau can save as much internal parts from the transmission as possible.
it's incredible to see the little things, the things that will never be recorded in history books, like that wire attaching the bolts together, what the threads looked like. Makes you think about who wound that wire and tightened those bolts, their story.
10:42 the panzer armorer kit has the tool for this. It's the split bearing puller. I've always wondered why it had a cupped inside, it made no sense for bearings (even tho it works on those too) now i know. It's for this gear as well (well, for the panzer variant). Because if you had to change the gearbox, you could just replace this gear, you had to take it from this and put it on the new gearbox (or viceversa). This gear is paired with its mating opposite. edit: 12:16 yup. You need a cupped one. That's so neat!
Thank you for the update. I probably would have been throwing the hammer at that gear. What patience he has. I wonder if a Porta power type press/puller would have made a difference? Anyway looking forward to the work on the gear box.
To pull a gear off, start by spraying with penetrating oil, then applying pressure with gear puller, you can use multiple hose clamps to hold the gear pullers arms on the gear, though the weld-ons were a good idea, then heating only one side of the gear at a time, not the shaft. Heat makes metal expand, and you want the outside to expand, expanding the inside just makes it tighter. Heat the gear up until you see slight orange and then cool it down with a garden hose, then spray it down again with penetrating oil and heat on another side of the gear. Gears that pull loads are Rockwell 62 or higher or they are made of cast ductile iron. The large ones are usually the cast iron and heat those but not to orange. And always cross your fingers.
Bonjour Dur travail cela avait pourtant bien commencé mais ! Faut jamais crier victoire trop vite Sais de la mécanique et en plus tres vieilles Bon courage ( vous n'en manquer pas ) mercivpour votre travail et votre patience Un français KING-AIR-148
amazing work as usual, i have worked on similar rotted classic engines , but am i the only one thinking why not heat the helical gear red hot for expansion from the drive shaft. im sure im missing something but thats my thought .
I would have tried heating the gear itself to red hot, then cold shocking the shaft with ice water, while having your puller tensioned as hard as you can. May have shrunk the shaft enough for it to let go , but you persisted and got it anyway, good job .👍
Yeah, great idea: heat the hardened steel and then start throwing water around just you guarantee to fvck up the hardening AND introduce random stresses into the metal for a part you want to reuse. If they were patient they would not have used WD40. They would have sprayed it with BDS, left it for a day or two, and used a bigger lever. Most of what they do is pretty fvcking agricultural and out of date techniques. They (mostly) work, but fvck me, they make it hard for themselves.
@@stevengriffin7873 If they're not saving the rest of it cut everything else away and start with soaking the gear in BDY solvent to eliminate the rust and then take to it with a wheel puller, perhaps? I just get frustrated that their solution to almost everything is a gas axe. They're butchers IMO. There's almost no finesse to anything they do. Which is fine given they own the stuff they're working on, but what really winds my clock is that idiots out there watching the videos think these guys are highly skilled and doing work at a high standard/level. Coming from a museum conservation background, I'm constantly horrified at most of what they do. Such is life :)
Yes I agree with the previous comment on freezing (CRC); but as a starter, then the application of heat. Another enjoyable episode with the guys at the workshop. A quality program allround.
I used to repair Enerpac stuff. Any sort of "portapower" hydraulic set up would've eaten that job but anyhow good job nontheless guys. Cant wait for the next episode.
SINCE the gearbox casing was completely fucked anyways, why not remove that entire shaft with all the gears on it, stand it up in the press and grab the helical output gear and press the shaft down and out like you did, but with the shaft and gears hanging underneath???? What am I missing here?
