Cracked me up to hear you say, "as you can see what a nice transition we have from shiny zinc plating to pleasing rust." (a little bit of paraphrasing) 👍👍👍
I have a question.....? I noticed that the old nuts are square, whereas new nuts are hexagonal ? Which are better, and why ? Thanks Dave !! Your 'secret recipe' (or is it just white vinegar ?) sure brought on the rust and everything looked authentic !!
What a wonderful thing to have been able to acquire that bolt and accessories rack from a retiring wheelwright 35 years ago. A great treasure, along with the other tools.
Funny I just had to find 42 bolts and some I had to make out of rusty thread stock put it in vinegar and Loctite for one of the nuts. Also I had to make a foam vinyl back pad. My friend bought an Ebay gym frame that came without the bolt pack, they first offered him 20% discount ;-) after a few weeks he got a full refund. That threaded bar 8mm stock was 40y old; it is a sad reminder of our old Blacksmiths shop in Lancashire UK When I cleared out the shop to sell in 2019 the grinding sparks/dust/grit from the walls and floor was very heavy I could not lift a full bucket our refuse bags we had to part fill or they would rip when you lifted them. One job we had was to make steak sizzler cast iron oval plates for a restaurant, my dad polished them to make them shiny, the Chef cried and we had to throw them into the forge to blacken them ;-) We loft the profit on that job in coke for the forge and a second delivery; to make up the chef did a couple of steak dinners for free ;-)) In the 1940s my granddad sold a wheel rim butt welder to a cousin who was a wheelwright then later as less carts were needed he started making barn doors and coffins and then later repurposing ex military HGV vehicles for domestic use. Herbert passes away recently he nearly made it to 100y old still working on DIY jobs.
Anyone who does not understand the notion that the devil (and the work) is in the details only needs to watch you at work! Thanks as always for sharing
I really look forward to Fridays...and more recently Wednesdays too :) That opening theme shot...it makes me SO COLD just looking at it! I swear it seems like the wind chill would be in the negative 20's...way too cold for this southern boy
Pretty neat trick to rust the new hardware to match the old stuff. Have to put that into my memory bank. Great job on the sheep wagon and it is coming right along.
I can look at the tips of many of those bolts and discern that those threads were rolled and not cut. I had thought that would have been rare 100 years ago, but you have inspired me to look up the history of the rolling process and indeed it is older than this wagon. So then, I jumped back to where you had the old hardware on your table and indeed those too show the "crown" around the tip, indicating rolled threads. Learned something today - can't hardly be a bad day now!
I use vinegar to remove rust from old sewing machine parts, my trick is a quick wash under a hot tap and into a pan on a low heat and spray of WD40 to stop the rust bloom. Sewing machines take up less room than your lovely carts ;-) and my wife will not let me work on a motorbike on the dining room table :-(( but I get away with old sewing machines. My oldest machine might be before 1880, it still works well. I one helped my dad in the 1980s make a large animal waggon that bolted on a flatbed lorry.
Поделюсь историей,которая произошла по моему желанию))).Возникла необходимость избавить болты от ржавчины.Очень большой ржавчины,хотя резьба на них была в отличном состоянии.Моя мысль работала так.Раз кислота способствует появлению ржавчины,то с точки зрения физики,она от неё и избавляет.Самый простой способ это сделать с помощью уксусной кислоты.Благо что эта кислота у нас есть в каждом продуктовом магазине.Купив этой кислоты,имеющая 72% кислотности я претворил своё желание в действие.Но,поскольку я такой же нетерпеливый,как Дейв,решил эти болты в уксусе прокипятить,чтоб химическая реакция прошла в ускоренном режиме.Сделал я это в глиняном горшке,так как в нержавеющая сталь от кислоты темнеет а алюминий разлагается.Кипятил я занимаясь другим делом и вспомнил про эти болты только минут через 20.Результат превзошёл мои ожидания.Ржавчина исчезла полностью.Но.....вместе с ржавчиной исчезла и резьба,тоже полностью)))).Хотел как лучше,а получилось как всегда😁😂
Здесь в магазинах продают уксус, в котором содержится всего от 4 до 8 процентов уксусной кислоты. Я забыл и оставил несколько ржавых болтов замочить на ночь, а когда вспомнил о них на следующий день, резьба оказалась острой, как нож.
Sir, if I may. (Ex-) sound engineer here. I suspect you have a lav mic somewhere under your leather vest. I would suggest to clip your mic on that very vest. Right now, the sound is muffled quite a bit from being under other garment (e.g. many of the high frequencies are lost). I'm pretty sure no one minds having a mic visible. This will make your voice much clearer. Love your work, thanks for posting so regularly! Best regards.
I really enjoy and appreciate your attention to detail, thanks for the update, going to be sweet deal when finished out, looking forward to seeing it completed.
Smooth, no rush and relaxing channel. I worked on restoring old homes. Pickling was the method I used on wood. and then I would stress the surface. using a chain, hammer and a gouge. Results was weathered wood.
I've had to antique hardware and I soaked it in muriatic acid. That took the zinc plating right off. Then I used gun blue on it to give it some darkness.
In the past I aged some bolts for a wood wheel barrow I was constructing and simply threw them in the wood stove to degrade the zinc. Yours turned out perfectly.
Hey, you're a real intelligent man. A good woodwright asn't anybody figured out that you can lift the sanding blasting cabinet off the ground and sit down? I have. And boy, he makes the job a lot easier.
Hi Dave and Diane ☺, thanks for another interesting video mate, just loved the ageing of the coach bolts, and the trick running them in a drill against the disc was realy slick. Keeping the square nuts all aligned reminds me of cabinet makers who did the same thing whith slotted screws, and gunsmiths would do the same thing also.The wagons realy taking shape now,
At the museum where I volunteer, we often have to take the plating off new fastners. We dip then in muriatic acid for just a few seconds and the plating instantly gasses off. A quick rinse in water and slow drying produces a lovely rust patena. However, the gas produced is toxic, so we do it outside and of course protective gloves are required. Just another way of getting the same results but it is very quick when a lot of pieces need to be done.
I quite like the contrast between the mismatched original left and right diagonal bracing and the restorers inability to do anything other than careful precision alignment of all the other metalwork and timber. I suspect the restoration is much more precise than the original work and old repairs -- but at the end, the wagon will look completely "right". Something any sheepherder would have been proud to use, a century or more ago.
A big kick for me is how the hardware is all 'clocked'. Memories of "learning at my daddy's knee", he was ADAMANT about 'clocking' hardware! Thanks, Dave!
When I wanted to get my bolts etc to rust, to age something, I'd strip the coating with acid, (you can use viniger), then wash with water, which makes it instantly rust.
Hello and greetings. Just lately I have been following along in watching your videos. Make me realized how busy you have been in your shop. Thanks for the updates. Keep up with the good work. 👍
I can see it now, 100 years in the future, an excited little old lady is appearing on Antiques Roadshow with "her great great grandpas sheep wagon" and the appraiser points out all the extra effort that went into making a "modern" replica look much older and its not a true antique! LOL
The angel Gabriel appeared to shepherds in their fields attending sheep---Good news of great joy in the city of David, a Savior is born! O come let us adore him.☆☆☆thanks for the chemistry lesson.
I got the idea from you to grind them down as you do to use on my customs instruments build for prehistoric planet series ...then I cold blue them and seal them up..works a treat
Do you think the grease bucket hung from the loop on the rear support rod? Little by little this wagon reveals itself as a engineering masterpiece for its time.
Every bit, every piece of wood or iron, that gets added to the sheep wagon or manure spreader adds to the total weight of the vehicle. After many decades of playing with airplanes, I think I can safely say that neither one is going to fly!
Hi Dave, may I suggest you look around UA-cam for Nickel plating electrolysis videos. The reason being that the process needs a sacrificial strip of Nickel that then gets deposited onto the desired metal. Anyway, my suggestion is that you follow the process but instead use your Nickel plated bolts as the donor material. P.S. Hydrochloric acid vapour is a Bas***d for causing rusting on exposed metal *even in your workshop if not covered. Loving your work fella' 👍
Another way to remove zinc that I saw Christopher Schwarz use is soaking the hardware in citric acid, You can get powdered citric acid wherever you find (food) canning and preserving supplies,
Some people turn rust to shiny, but you turn shiny to rust. Jokes aside, I perfectly well understand what you are doing, aging them to fit naturally. As a movie prop, I suppose this waggon would be very nice indeed.
I also use muriatic acid (or anything else on hand) because I don't have a sand blaster. That takes care of the plating. Then I drop them in a bath of Clorox bleach. So far, it the best oxidizer I have found. I leave them until they get to the look I want. I am going to try the Vinegar formula you use and see how it compares. It is always good to learn a new method. Keep up the fun projects.
Hi, a simple method to remove Zinc plating ang forming rust is immerse the fasteners into a HCL and after the reaction stops bubbling rinse in water. Rust starts immediately.
Just dip them in muratic acid for 5 minutes. Pool cleaner. Removes the coating. Do it outside. Do it all the time for things I want to weld. Rinse with water. Water neutralizes it. It will eat your skin and concrete. They will start rusting within minutes. You can reuse it. Glass or plastic jug.
10% muriatic acid solution will eat the zinc right off anything galvanized. I use galvanized iron for standing seam roofing all the time. If you wash it with apple cider vinegar(a very mild acid) it will take paint without hurting the coating.
While any oxidizer will cause bare metal to rust, and your vinegar certainly does cause rust, I always used a little gasoline. I make some horse shoe art (hall trees, coat hooks, wine racks and such). When someone asks for a 'rusty' look I put a little gas in a spray bottle. One coat and five minutes later they look like they have been laying outside for a hundred years. I let them air dry for couple of hours before hitting them with a clear coat. Needless to say, I do not do this near an open flame.
Try soaking the zinc plated bolts in Muratic Acid aka hydrochloric acid. The zinc should react pretty quickly. It will produce hydrogen gas so make sure there are no open flames around.
The vinegar does not dissolve/corrode iron, it removes everything off the iron leaving a very unprotected and most the times very porous iron surface. Steel being an alloy has the extra material removed from the iron in it making it seem like it is being eaten. Thats why you have to be careful with harden steel in vinegar because of the higher levels of other material, it becomes more fragile. I have seen some take and heat then vinegar dip (not hot going in just it was heated to red hot before dip) but I am unsure if that allows deeper rust formation or if it just makes it it off colored to add to the rust formation.
This channel is a US national treasure. Incredible stuff!
Not just the US
The Master '"Magician" is at it again. It is the little things that make all the difference. Appreciate the opportunity to follow along. God Bless You and Mrs. Engels.
Glad to know I'm not the only one that gets "a little ahead of myself", Dave.
Cheers
It's been an absolute treat watching you do the sheep wagon and the manure spreader together Dave, thank you once more.
Cracked me up to hear you say, "as you can see what a nice transition we have from shiny zinc plating to pleasing rust." (a little bit of paraphrasing) 👍👍👍
I never tire of watching you figure things out. Your thought process and your experience go hand & hand.
So relaxing to watch you confidently rebuild an old wreck into a thing of glory.
Yes! It amazes me how Dave saw this in his mind's eye.
I have a question.....? I noticed that the old nuts are square, whereas new nuts are hexagonal ?
Which are better, and why ? Thanks Dave !! Your 'secret recipe' (or is it just white vinegar ?) sure brought on the rust and everything looked authentic !!
What a wonderful thing to have been able to acquire that bolt and accessories rack from a retiring wheelwright 35 years ago. A great treasure, along with the other tools.
The attention to detail is what set you apart from all the rest. Well done my friend..
As usual your care to replicate the aged condition of your project is extraordinary. It is the care in fine details that makes you a true craftsman.
What a nice pleasure it is to watch this wagon come together
She's really coming together and looking really good... looking forward to the finished project.
I always enjoy the opening shot a fine weather report I bet the cows are snuggled in to. As always thank you for your time. Paul
Have a good weekend, old boy. You've earned it. 🇬🇧
A heartwarming riches to rags story 😅
Watching you do your fine work is relaxing for an old man in my late 80's such as my self.....Thanks Dave.....
Old F-4 2 Shoe🇺🇸
Funny I just had to find 42 bolts and some I had to make out of rusty thread stock put it in vinegar and Loctite for one of the nuts. Also I had to make a foam vinyl back pad.
My friend bought an Ebay gym frame that came without the bolt pack, they first offered him 20% discount ;-) after a few weeks he got a full refund.
That threaded bar 8mm stock was 40y old; it is a sad reminder of our old Blacksmiths shop in Lancashire UK
When I cleared out the shop to sell in 2019 the grinding sparks/dust/grit from the walls and floor was very heavy I could not lift a full bucket our refuse bags we had to part fill or they would rip when you lifted them.
One job we had was to make steak sizzler cast iron oval plates for a restaurant, my dad polished them to make them shiny, the Chef cried and we had to throw them into the forge to blacken them
;-) We loft the profit on that job in coke for the forge and a second delivery; to make up the chef did a couple of steak dinners for free ;-))
In the 1940s my granddad sold a wheel rim butt welder to a cousin who was a wheelwright then later as less carts were needed he started making barn doors and coffins and then later repurposing ex military HGV vehicles for domestic use. Herbert passes away recently he nearly made it to 100y old still working on DIY jobs.

Wow, a sandblaster with a window you can actually see through!
Both wagons are coming along great - the sheep wagon and the sh*t wagon.
I really look forward to Fridays...and more recently Wednesdays too :)

Thoroughly enjoyable visit to the shop . I'm envious and interested at the same time . Marvellous . Hope Mrs Engels and the geranium are fit and well
We learn so much from you
Looking Good Dave , is getting there. Your teachings to make rust is awesome. Keep up the great videos and sharing with us. Stay safe . Fred.

Another "EE" video. (Entertaining and Educational). Thanks Dave. Have a great day and stay safe.🙂🙂
Another day with the Professor.
Thankful that you have to remove the writing on the bolts... Much easier than adding the writing! 💖🌞🌵😷
Great video,amazing what you go thru to make everything like it was old to go with the era of the wagon.very nice 😎😎😎👍👍👍
To remove the zink on hardware, I have always soaked it in acid, but a sand blaster definitely works as well.
Smooth, no rush and relaxing channel. I worked on restoring old homes. Pickling was the method I used on wood. and then I would stress the surface. using a chain, hammer and a gouge. Results was weathered wood.
I've had to antique hardware and I soaked it in muriatic acid. That took the zinc plating right off. Then I used gun blue on it to give it some darkness.
Quite a change in pace making everything look old instead of new. That's quite the trick to rust up those new bolts
You never cease to amaze. Thanks for sharing.
I'm going to start calling you "Rusty". Great work, reminds me so much of my father who repaired furniture.
Stay safe and we'll see you next week.
Wow you still have real winter!
Over here it's a cozy 12⁰C 52⁰F outside with the occasional drizzle
In the past I aged some bolts for a wood wheel barrow I was constructing and simply threw them in the wood stove to degrade the zinc. Yours turned out perfectly.
^- Dave, the patina rust antiquing matched wonderfully with the old originals. Amazing.*
*- Good for you.*
Hey, you're a real intelligent man. A good woodwright asn't anybody figured out that you can lift the sanding blasting cabinet off the ground and sit down? I have. And boy, he makes the job a lot easier.
Very nice sir,you a patient man

Muratic acid is effective at removing plating. If not washed off it will promote rust as well.
I guess I'm not alone chucking fasteners in a drill and making them look like something else thanks for another informative video🤗😎🤗😎
It's coming together.

FANTASTIC AS USUAL,LOOKS GREAT❤
I'm always learning tips and tricks from you. Thanks for the video Dave!
Hello and greetings. Just lately I have been following along in watching your videos. Make me realized how busy you have been in your shop. Thanks for the updates. Keep up with the good work. 👍
To rust or not to rust that is the question!
Thanks Dave for the wonderful presentation. Great content.
You are amazing ! Congrats !
I can see it now, 100 years in the future, an excited little old lady is appearing on Antiques Roadshow with "her great great grandpas sheep wagon" and the appraiser points out all the extra effort that went into making a "modern" replica look much older and its not a true antique! LOL
That's a first but it works 💪 😊
Only thing beat ur vids would b seeing your craftsmanship in person...
You're quite the old dog with all these new tricks.
The angel Gabriel appeared to shepherds in their fields attending sheep---Good news of great joy in the city of David, a Savior is born! O come let us adore him.☆☆☆thanks for the chemistry lesson.
You can make an antique Dave and marvel how you obtain this but do you have something to make us new again? 🙂 Thank you once again sir for sharing.
Look up his "mud wagon" build, about the only thing left of the original wood was the idea! 🙂
I got the idea from you to grind them down as you do to use on my customs instruments build for prehistoric planet series ...then I cold blue them and seal them up..works a treat

To clean up bolts, washers etc from zinc, you could dump them in chloridric acid. It only takes a few minutes

Rust-oration!
Have you looked at McMaster Carr. They sell bolts unplated.
While any oxidizer will cause bare metal to rust, and your vinegar certainly does cause rust, I always used a little gasoline. I make some horse shoe art (hall trees, coat hooks, wine racks and such). When someone asks for a 'rusty' look I put a little gas in a spray bottle.

"Somethings never change" and when it comes to the wagons...keep them as they were.
thanks Dave great job you are a master at your skills

You'll need to rust all your nail heads now 😁
