I was thinking a foot-pedal, for an instant on and off. That just looks like a night-mare...with the automatic teeth pulling everything in...then you explained about the tension. Really nice design, good video!
I love this! Reminds me of a similar conversion my Dad did to a rotary honey extractor - strapped a whopping great 12V motor and belt drive onto the handle with a speed controller so Mum didn't have to turn it by hand for hours at a time!
Good job I built an ebike with similar battery line up. Great to hear the Cockerel in the background he's a busy boy I'd say almost as busy as you Kris👍
I try to watch your videos while I’m getting ready for the day...I end up watching and NOT getting ready😆!🙄🙂Thanks for this post! Glad to hear that you have a nearby source for wool too.
Well I had a bath today, it tired me out. I’m in a bit of a rush as it’s nap time. All this work you are doing Kris, is tiring me out. Seriously though, I really look forward to your posts. Keep them coming.
I would like to own such a device.I build a transmission line speaker.The box of the speaker has a tunnel from the back of the speaker that goes up and comes back down to an opening in front of the box.This energy would be lost in a closed box.This tunnel is filled with wool at a density of 1 pound per cubic foot.I found some wool in hair fiber bats,it needs to be carded to fit in the tunnel at the wright density.I made 2 brushes with peaces of wood (shaped like a brush)with small finishing nails.It works but its a lot of work.This machine would save me a lot of work and time,wonder where its made ? Bye. Lucien
cool project! I love combination of the home sourced natural resources + hard work, to create something. only then you appreciate the value of everything.
This made me smile the entire time watching. Thank you for your brilliance and I hope your lady loves it. Would also love to see the spinning process to finish.
Very nice video Kris, you video skills have improved a lot since the beginning. Also, great project for li-ion batteries with proper balance charger connections, you are a man of many skills.
Great content Kris. I only recently discovered your channel, around about 5 weeks ago and I have been battering my way through all your videos. Really easy watching, entertaining and educational. Keep up the hard work.
Really awesome. I enjoyed the original build video and loved this upgrade and another chance to watch it in action. It would be easy to hook a drill to it to save labour, but I appreciate your knowledge of electronics that allows you to have so much more control.
Very sound little upgrade project from all points of view. Loved watching the larger pieces near the end of the video disappearing into the machine... like little fluffy clouds being eaten
Hey Kris, I would recommend a battery spot welder instead of soldering directly to the batteries. Lithium ion batteries can explode when you solder directly to them. You should spot weld a tin strip to the battery and then solder to the tin strip. They have spot welders are on ebay and not terribly priced. I have also seen people make them from spare parts and a car battery.
i have soldiered 1000s of lithuim cells with no problem high power the soldering iraon the bttter this way it heats and cools befor tasnfer to rest of cell happens
@@1981dasimpson Not challenging what you are saying as I have also seen people solder lithium batteries. But it is not a good thing to do regardless of heat transfer. Even a little bit of heat can damage the plastic separator, pressure protections, or if the heat is left on a bit too long, the main internal lithium layers. So it is good advice to not directly solder on the battery. Not saying it will blow up or something... LOL it will just degrade the battery.
I've also soldered 100s of lithium ion batteries. The worst part about it for me is that it's much more of a pain in the ass if you are doing a lot of them. However, if you are just doing a few then soldering is fine. Besides, he is using Lithium Iron Phosphate which is a much more stable chemistry battery. Perfect choice of battery for a project like this!
Your are so creative and clever Kris. I'm sure Dot is going to enjoy this once she gets used to the speed. Have fun with it Dot and you both stay safe and well.
Kris you are a genius ! Dot can now work a lot more wool and you will get your sweater much quicker or is Dot going to dye the wool with natural colours. Like growing some rape flowers to get yellow, some kind of wild purple flowers to get purple or pink etc. Both of you are real pioneers with this adventure of yours❣️🤗
I randomly stumbled upon this video (It came up in my suggestions) Looks very efficient. This is where I offer unsolicited advice ; - ) Add a half moon cover over the intake drum on a hinge so it's easy to access for removing jams, but has a low feed opening to minimise the risk of fingers or clothes getting snagged. Add a pull out stop cord switch that cuts power if it gets tugged out Or an emergency stop button. Yes it has a switch I know, but a "Big red button" is usually easier to see and remember as when your fingers get nipped by the in-feed wires clarity of thought will go out the window! Great build especially the use of natural materials. I'm going to have a look through some of your other video's now, Bill.
Hi from Oregon! Thanks for the excellent vlog. You answered every question that popped up, how’s he going to attach motor to shaft, why are the fins rubbing, what happened when I stick my finger in first drum, on and on. Bravo on a home made project! Can’t wait for another one of your well made videos.
A battery is nice and all but it makes more sense to just run it from the wall, since you probably won't be running all around the place using it. Also, a big red emergency stop button would be nice.
can you show us how dot then processes the wool into a usable material, would be nice to see a more traditional method rather that a factory churning it out :)
Blown away Kris! What a brilliant build, the missus must've been well chuffed with that! Loved watching you make the box and the distressing with the blowtorch...brilliant idea. Beautiful looking thing, and really good, reliably built motor and battery setup too. Blown away mate, honestly blown away. The tool chest you did recently was way up there, a real thing of beauty, but this 👌 Have you built a powerwall by any chance? You look like you know what you're doing with your batteries, balancing etc. Can't wait to see what's coming next. Thanks again for the vid. Awesome 👍
Add a large red emergency stop button for safety! That would be painful to get your sleeve stuck in there. The emergency button can be pounded on to stop the machine quickly.
Nice! I would have given the option to shift from main power to battery though, making the carder portable... carding sessions can be long...note to Dot: you can use a hair brush with long bristles to pack the wool on the big drum while running, it will also balance the thickness .
Dear Kris Harbour. 👍👌👏 Very well done again and as always (video and work). What a great update and very helpful for your girlfriend. I don't know why but somehow I missed to watch this video until now. By the way: I wonder why there are not more views. Maybe the title should have better been more like: "Drum carding machine upgrade." So please kindly allow me to suggest that you consider to repost the video with a new title. Because utube would recommend it more if LifePo4 battery is not mentioned at the beginning of the title. Additionally: People interested in "wooly stuff" may search for drum carding machine but definitely not for LifePo4 battery powered... Thanks a lot for making teaching explaining recording editing uploading and sharing. Best regards luck and health to all of you.
I appreciate that you've considered the potential risks of the system. I hope you don't mind, I might still suggest a finger guard at the intake and also a foot petal switch that has to be fully pressed for the drum to spin. (Sorry, I hope I'm not adding to the safety nagging)
Wow, this is Very Good! Your girlfriend and you are amazing! I like the rooster at 2:58/2:59!, 5:45, 12:4012:51...I stopped counting! Active bird! Maybe he wanted to help.... How did you learn to do thais? Looks great! (Kitty cat at 16:59 came to help). This is so interesting! I’ve always been interested to see how these things are done. Maybe you can get Dot to spin the wool into yarn for us to see! Great video and explanations! Love your accent!! ❤️ from America.
Two questions that weren’t in your last Q&A...how difficult is it to get your mower onto the roof and what do you do with all the junk mail from electricity companies asking you to change energy providers?😁😁 All the best to ya Kris
Good day Kris and Dotty. So let's start off with a joke, I've met you and I know all that conversion is just for show and really you have just grabbed a field mouse and put it on a spinning wheel 🤣🤣🤣🤣. Amazing work again pal, loved it when it was manual but even better concerted. So next true fact. When you add subtitles to your video, every time a power tool is on it says music is playing. Now isn't that the truth. You working on your tools is music to my ears. Also from time to time some tools make the subtitles read applause. So I'm guessing your tools are applauding you at the same time. Keep up the good work you two. All the best Keiran😍😍😍😍😍
I love watching you make stuff. You know so much (or at least research to teach yourself) that it amazes me. The only videos I don’t watch are the hydraulic stuff with the water - on,y because I “don’t get it” and can’t wrap my head around it, lol. Thanks, as always for sharing. (Edit: “hydroelectric!” See, I don’t even know what it’s called, lol)
Great Design and Excellent workmanship on the motorized build! I am sure it will help her produce more spun wool!! Much success to you all !! Liked !! Subbed !!
So I am a little worried that even with the fan, those batteries could get hot because you wrapped them in that tape and basically created a blanket around them. Would only be a problem in the summer, but still something to think about. Maybe a thermal fuse would be good to add to the inside of the battery pack. Better for that to blow than one of those batteries. Great project. If this is the content we can expect now that you have a shop, your channel has a bright future.
Where can a buy a spanner like the one you used at the beginning of the video? Also a tip for you, a motorised version is going to be creating potentially too much heat from friction and definitely needlessly draining battery. You should try to reduce friction at each one of those spindles and gears which each have huge surfaces touching the side wall for no particular reason.
Found myself watching your very interesting channel and couldn't help thinking that you are embarking on your own micro industrialization. It seems it doesn't matter what angle we come from human instinct for progression...and there seems to be the conundrum.
You can insulate your home with that! Need a receiving drum with a circumference equal to your stud bay height to really make it an easy and effective install... but still..... cool video.
The only thing I would ad is a p.c.m. (power control module) to shut it off when the battery gets too low but also to monitor the battery level status .
Nice work! Question: Since feeding the wool under the front roller requires only a tiny bit of space near the platen, Why not add a hand guard in front of the first roller? Make it difficult to accidentally get fingers (or shirt sleeves) under the front roller whilst the wool can still be slid under with ease. ?
Great job as always Kris but maybe a dead mans foot switch for safety? It would only work while your foot was on the switch so if something bad happens lift your foot and it stops. Just a thought as I know most people panic in an emergency and don't think straight.
I suggest to shim it between the main drum and the card cloth in the center of the 1/4 off the main drum that is not carding due to warpage and "out of round", to try and get it back to the correct distance to the second wheels pins(bristles). Seems simple enough to jam a thin cut of appropriately (measured) thick shim material or bamboo kabob stick in there. Might take you a minutes time. I figure, if the carding cloth is sufficiently stiff a 1 inch shim in the center of the warpage could appropriately support whatever a 1/4 of that wheel measures and you're back to 100%.
In the next phase we see Kris add a ramp for the sheep to approach the auto-shearing attachment that feeds the carder.
🤣🤣🤣
I was thinking a foot-pedal, for an instant on and off. That just looks like a night-mare...with the automatic teeth pulling everything in...then you explained about the tension. Really nice design, good video!
I love this! Reminds me of a similar conversion my Dad did to a rotary honey extractor - strapped a whopping great 12V motor and belt drive onto the handle with a speed controller so Mum didn't have to turn it by hand for hours at a time!
That jig for making the corner joints is SO SATISFYING.
Hi Kris, love watching your video's and seeing the homestead finally coming together after all your hard work. Good luck to you and Dot.
A fantastic little machine made even more so. I bet Dot is over the moon with that. You are a very clever chap.
This Kris guy is just amazing!!! Makes things seem so easy. Wonder if anyone ever told you that you are a genius. You are a genius Kris!
Good job I built an ebike with similar battery line up. Great to hear the Cockerel in the background he's a busy boy I'd say almost as busy as you Kris👍
Love it when a plan comes together. Thanks Kris ... I'm sure Dot will get hours of use from this very helpful machine.
Literally my favourite UA-camr, nuff said.
A sit down peddle powered version would be sweet as well ;) hook up a exerciser bike under the table hahaha. You are one very productive fellow.
I try to watch your videos while I’m getting ready for the day...I end up watching and NOT getting ready😆!🙄🙂Thanks for this post! Glad to hear that you have a nearby source for wool too.
Would love to see the process of spinning the wool.
^^^^^^ he's right ya know!!!!
More content just waiting to be filmed.
time to do plan B..... build your spinning wheel (unmotorised)
Well I had a bath today, it tired me out. I’m in a bit of a rush as it’s nap time. All this work you are doing Kris, is tiring me out. Seriously though, I really look forward to your posts. Keep them coming.
Its a bit like how we joke at work, "I've got fk all to do today and I don't think I'm going to get it all done"
Nice story bro
Great electronic skills, variable speed was awesome. Also really enjoyed seeing it work.
Looks very professional the only thing I would change is the on off control to an emergency cut out
Don’t want Dots hands in danger
Very impressed
creating lasting items with function and beauty. well done Kris.
Can we see what Dot's made with her spun wool? :)
I would like to own such a device.I build a transmission line speaker.The box of the speaker has a tunnel from the back of the speaker that goes up and comes back down to an opening in front of the box.This energy would be lost in a closed box.This tunnel is filled with wool at a density of 1 pound per cubic foot.I found some wool in hair fiber bats,it needs to be carded to fit in the tunnel at the wright density.I made 2 brushes with peaces of wood (shaped like a brush)with small finishing nails.It works but its a lot of work.This machine would save me a lot of work and time,wonder where its made ?
Bye.

Yes, please :)
If found the channel in my recommendations today and it's awesome.
That's Awesome!!! Great Job Kris... You are one Smart Cookie!!! Thank You for sharing, Much Love and Be Well to You and Your Family. 💙
Watching you in the old shop and new shop is amazing. Your knowledge of so many things!! Great work!
A man of many talents.
It needs a big red button, just in case.
Yes! A button that launches all missiles at Safety Sallys.
@@ButterflyMatt THATS my wife you speak of!
Beautifully done. That thing could take a whole sheep -- barely even got it to bog down a little with massive fleece going in.
cool project!
I love combination of the home sourced natural resources + hard work, to create something. only then you appreciate the value of everything.
Please make a spinning wheel next!!!
Damn you beat me too it!
I'm Canadian,so I usually wouldn't use this term to describe anything,but this whole mechanism is a treat.Well done Kris!👍
Looks good. Love the ingenuity. Three thumbs up. I have a soft spot for belt driven gear.
Never carded wool in my life , but I want one !
Usual neat fascinating job 💪🎊
Every time I watch one of your video's I learn more. You are remarkable talented.
Yeah, applause applause. Well done. Works fantastic. I am sure Dot is delighted.
This made me smile the entire time watching. Thank you for your brilliance and I hope your lady loves it. Would also love to see the spinning process to finish.
Very interesting. Love it when when an 💡 becomes a plan and a plan becomes a project. 👍🏻

The heat from a soldering iron permanently degrades their capacity
Nah - they are fine. Also, these are LifePo4, not regular lithium fire starters lol

As the second iteration you could call it cardiB 😁 you always impress with your skills.
A battery is nice and all but it makes more sense to just run it from the wall, since you probably won't be running all around the place using it.
Also, a big red emergency stop button would be nice.
well done kris. I'm sure dot is pleased with that. very nice share.😊
Son....that was brilliant! And now I would love to see What 'Dot' makes with that wool 🤗
Kris, I am amazed at the things that you can do. Great idea, great execution. Thanks for sharing your talents.
Congratulations from France ! That's a great job ! 👍
can you show us how dot then processes the wool into a usable material, would be nice to see a more traditional method rather that a factory churning it out :)

Hello from Italy! Really nice works each time 🙂 Complimenti e tanti saluti!
Outstanding again Kris... no end to your inventiveness!
that was a great relief to her, I can't imagine she was doing that by hand.
don't compare it with a bicycle, these are hand-operated and bicycles are not

(Sorry, I hope I'm not adding to the safety nagging)
Rouverius I agree a finger guard seems like a really good idea. Would make me feel better if I were using it.
I'm probably being silly how about a pair of chain mail gloves?
I was also thinking foot switch from the start.
I like foot pedal as well, need to keep Dot safe!
Your going to have to build, Dot her own Shop. 'Dot's Spinning Wool'
Wow, this is Very Good! Your girlfriend and you are amazing! I like the rooster at 2:58/2:59!, 5:45, 12:40 12:51...I stopped counting! Active bird! Maybe he wanted to help....

Can you do a vlog of Dot spinning the fleece into wool??
I noticed you don’t use a riving knife on your table saw? And I thought the use of dado stack blades were illegal/banned in the UK?
Genius! I would love to see what Dot makes with the wool.
I’m a smidge surprised you didn’t choose to go with Treadle power on this. This is much more compact though. Great job!
Great Design and Excellent workmanship on the motorized build! I am sure it will help her produce more spun wool!! Much success to you all !! Liked !! Subbed !!
Wow - amazing skills, lucky lady!
This is a great project. I would love to see how you would build a picking machine.
Fantastic! Glad to know that there are some safety features in the way it works.
Hey Kris that’s a great idea and video! 👍👍💯💯
You are such a clever lad. You absolutely amaze me.
Lets see a video of her spinning the wool! Raw wool to complete sweater!
Thanks for your video.... Dot needs an electric spinning wheel now, again, thanks for sharing.
This machine has everything, useful, saves time and an element of danger 😄😄😄😄
And, of course, charging with your turgo hydro turbine..... I breed a few Herdwick sheep, I will send you the fleece :-)
Maybe add a finger guard just in case, better safe than fingerless!
I’m ready to purchase a wool sweater when ever she makes one!
So I am a little worried that even with the fan, those batteries could get hot because you wrapped them in that tape and basically created a blanket around them. Would only be a problem in the summer, but still something to think about. Maybe a thermal fuse would be good to add to the inside of the battery pack. Better for that to blow than one of those batteries. Great project. If this is the content we can expect now that you have a shop, your channel has a bright future.
this is truly amazing. loved this vid.
What a lovely thing to do for Dot!
Man project too!
Awesome
Amazing craftsmanship here, the only thing I can't love about it is the industrialized hand accident that's possible
Where can a buy a spanner like the one you used at the beginning of the video?
Also a tip for you, a motorised version is going to be creating potentially too much heat from friction and definitely needlessly draining battery.
You should try to reduce friction at each one of those spindles and gears which each have huge surfaces touching the side wall for no particular reason.
Very cool, I will look forward to the next vid on it's safety features.
Found myself watching your very interesting channel and couldn't help thinking that you are embarking on your own micro industrialization. It seems it doesn't matter what angle we come from human instinct for progression...and there seems to be the conundrum.
You can insulate your home with that! Need a receiving drum with a circumference equal to your stud bay height to really make it an easy and effective install... but still..... cool video.

consider a pedal as a safety measure?
