I think most of those jaw crushers like that use bushings on the eccentric shaft instead of bearings. The bearings just can’t take that kind of abuse. I have a rock crushing/gravel pit excavation company about a 3000 feet from my house. Go up there often.
Was thinking... I bet you could adapt your firewood conveyor system to work with this crusher as well. That way, you can load the crushed material right into a trailer as it's being crushed so you can move it around to where you need it easier. Just an idea I had, not sure if it'd actually work or be practical in the end.
I think we have found secret son of Jamie Hyneman. Has engineerin/fabricating skills and giggles like a school girl. Just missin round sun shielded glasses, baret, wallrush moustache and always perfectly white flanel shirt.
Im just a simple wood butcher by trade so I didn't understand half of what I just watched, but when It started forming on the lathe then it all made sense,, regardless of that Im always in awe of your skills and simple no nonsense approach to doing things - thank you for continuing to create and inspire 👍
Not surprising but always entertaining watching you put your limitless skill on show again and again! Brilliant as always Donn. Cheers from Sydney Australia 🇦🇺🦘🐨🍺🍺🐨🦘🇦🇺🇪🇪
I have been living whole my life seeing stone crusher, my dad started stone crusher business when he was young and m continuing his business, m must tell you that m really impressed with your own made stone crusher, it's very close to perfect... like you use to say "pretty good"
Someone has probably already said this but what the hell, I'll say it again. You're a very gifted craftsman with incredibly versatile talent. Nice job on the camshaft!
I love it !! Great design very well thought out !! This will crush some rocks for sure and I believe that shaft will hold up fine . 👍👍👍Great job as alway's !!
I suspect it won't be spinning fast enough to need to worry about that. It depends on the type of rock he wants to crush, but I think it'll need a lot of gearing down for a typical 6-10hp engine to run it.
@@mikeznel6048 it will need a massive flywheel and be balanced because rock crushing machines are normally run at 3000-4000rpm as rock breaks easier when struck repeatedly with a high impact velocity
A masterpiece! I hope to make something similar, this has been such a valuable series for me. I plan on crushing a LOT of rocks eventually. Thanks loads
My three-jaw would have tossed that cam after about 30 seconds. It doesn't like interrupted cuts. My holesaws last a long time because my drill press sucks. It stalls out before it breaks the teeth off. I also add compressed air to help clear the chips or back it out often and run a wire brush on the teeth for a second. Nice video, I hope the build is as good as the content you put up on your channel.
I can't wait to see this thing work. I am kinda familiar with what a rock crusher does. Being around these but much bigger as I was growing up at my grandpap's stone quary here in the USA state of Pennsylvania. I dig it. Keep up the great work. 👍
I have a idea for you my friend !! your next projekt should be a universal hanging crane inside the workshop ! you really need a hanging crane for lifting everything instead of that Motor-crane :P I know you can do it . You are a master constructer in my appinion :)
Hey thanks to share your knowledge ... When I watch "jaw rock crusher build" video I wondered and tried ımagine how made You shaft. This video was very satisfy
Always interesting to see how other people do things, I've turned one before using a 4 jaw chuck in the head and tailstock. Offset each side equally using dial indicators
They do make wedges for bolting through channel iron. I used thousands of them in steel buildings and on crushers we rebuilt for the gold mines here in S.D.
The first thing I thought was wether the offset in that cam would be enough. You said the same thing just as I was thinking it. Looks friggin awesome, though....just like always.
I think it should be enough. You do not really need to move the plate that much even the smallest amount is enough to bind and crush rocks. Someone said maybe 10mm to 20mm is the offset. Though I think it will work very well. If not its just a new shaft that has to be made.
Needed a spot face tool for that channel hole , used on castings to machine it flat for nuts and washers , like a end mill upside down really handy for jobs like that!
I'm surprised any tapered flange channel still exists. Channels and beams both changed to parallel flanges about 35 to 40 years ago here in NZ. I'm old enough to remember using tapered washers which are still available.
11:00 I'd feel better with more radius on the transition from the bearing to the cam. 13:20 Looks like you mitigated it by tapering the cam side. Should give you a shot for success.
Nice turning. How did you determine the offset or was it in some plan for such a crusher? Project looks great and I will certainly watch for the rocks to crush... Thumbs Up!
Interesting way to go about removing the angle from the C channel. They do make angled square washers for that because that’s how structural steel is assembled.
There used to be special tapered square washers available to square up bolts in the flange of old fashioned "I" beams and "C" sections before parallel flange beams and C sections. 🙂
Is the toothbrush while drilling just to conserve oil? make less of a mess? both? or are you using that for a different type of oil? I've been wondering about this for a few videos. I'm guessing it is just to make less of a mess.
I wonder if those bearings will take the pounding or if bronze bushings would be better. The load is more spread out on a bushing. I suppose we'll know soon enough.
When your good looks won't take you where you want to go, then reinvent the wheel. I wondered how to make a straight line "Oblong" and then call it a crankshaft theoretically.... right?? Same principle but less journals on the unit and no connecting rods. Hardly wait to see it in operation... Just hope that the jaw is big enough to grind the stone. I am fairly sure where you live there are enough rocks to line the ocean floor and make a highway to the usa. I had a garden in a small town I lived in. Nice little town and well named... Rockport Washington. For every shovelful were at least fifty rocks of all sizes as well as the ones that were big enough to build a house IN them.
So question. I hope you are not going the let the cam run against the back of the crusher plate right ?? Are you going to use rollers perhaps for the cam to run against? Will you install springs to keep the plate pressed onto the cam ?? It will clatter if you don't. Will you use a flywheel for the camshaft ?? It will take care of balancing the camshaft and inertia will make it go smoother . I would case harden the camshaft . It will get dusty around it and be ground away , that be a shame of such a nice camshaft
I hope you have something planned for the bottom pivot points on the moving plate . Dust and grit will eat away on it if you are leaving it sitting in the slots without any support with bearings or such

👍🏻 A trick I use when using a holesaw, is to drill small holes in the cut around the circle no bigger than the blade to help remove chips.
I'll have to remember that! Cheers!🤙
I’ve seen that same idea used with a hole saw in wood as well. Anything to allow the chips to clear and prevent binding.
Or spend the money and get a broach cutter. Right tool for the job.
One about 6mm hole is good on the circle if you dont mind the extra hole.
@@JuhisTube
Just drill the clearance hole either inside or outside depending on which side is the waste side of the cut. 🤷🏻♂️
Legend has it that Donn is still stood there, twiddling his home made camshaft and giggling like a school girl. :D
Hahahaha

I am inordinately pleased that the solution to the tapered plate you're putting the bolt on that I came up with what's the same as the one you used.
Watching your work is very enjoyable, I wish the videos would be longer
I'm foreseeing a future overhead hoist build. Lord knows he needs one. Nice work. 👍👍
By the way: you are THE FIRST to show the toggle-plate setup even thou that's so crucial...Just building one too right now...
I'm just...impressed! Well done to you, what a joy it is to watch you work 👌
Im just a simple wood butcher by trade so I didn't understand half of what I just watched, but when It started forming on the lathe then it all made sense,, regardless of that Im always in awe of your skills and simple no nonsense approach to doing things - thank you for continuing to create and inspire 👍
Donn I got you on how you will get motion now. That is pretty cool. This is going to be a super awesome build once done.
Donn you are an amazing engineer! Your problem solving is awesome! 🙋 Greetings from Texas!
Le cose che costruisci hanno una durata pressoche eterna !! Hai raggiunto livelli eccelsi,Bravissimo 🔝
Not surprising but always entertaining watching you put your limitless skill on show again and again!
Brilliant as always Donn.

Donn, you are a modern day Genius ! I love watching everything you post and Your edits are always Top Notch...
Always an awesome build on your channel. Thanks
Very interesting to watch, never thought of how to make things crooked by purpose on a lathe!
:-D
Thx for the vid!
Someone has probably already said this but what the hell, I'll say it again. You're a very gifted craftsman with incredibly versatile talent. Nice job on the camshaft!
Как всегда все на высшем уровне мастерства!!!
your work never ceases to amaze me.
Eccentric shaft on the lath is genius, great video 👍
Watching you throw chips and make whatever you need is inspirational! 👍
Ñ
That was awesome Donn, showed some great information and fabrication again. Really enjoyed the video, thanks for sharing with us. Fred. 🙏🏻🙏🏻👍👍👏🏻👏🏻👋👋
It’s simply beautiful. 👍
Thanks man!
I love it !! Great design very well thought out !! This will crush some rocks for sure and I believe that shaft will hold up fine . 👍👍👍Great job as alway's !!
Hey, Donndiy!! Great work!! Really enjoy your invetivness.. Awesome jig work. That's the key, precisely made!!
Thanks to Video Donn! Allways nice work! 🎅🏻👍🏻👍🏻👍🏻🔧🔩🇫🇮
Hello Donn,
Looking great, can't wait to see the
finished product.
Thanks for the video, and have a good week.
Donn, will you need a counterweight on your camshaft to reduce vibration, and will you use a flywheel to build up momentum? It's looking good, so far.
More than likely will need a flywheel and probably would need a balance shaft but we used a counter rotating drum crusher when I worked at the quarry
I suspect it won't be spinning fast enough to need to worry about that.
It depends on the type of rock he wants to crush, but I think it'll need a lot of gearing down for a typical 6-10hp engine to run it.
Not gonna be spinning g fast enough to need a counter weight.

Damn Donny. U r a metal wizard!
Hello Donn good job looking good see you next video
I can’t wait to test the crusher when completed. I’ve started searching scrap metals now to build mine.
Very cool. Have a great build!

Coming along nicely! We shared this video in our homemade tools forum this week :)
"in the bin" I see you're a man of culture as well sir

Комментарий в поддержку канала и ролика, а также труда мастера.
That eccentric jaw shaft assembly is known as the pitman..... nice work.
what an interesting project you got there!
Cheers!
Nice work
Waiting for the next episode👍
Nice lathe work!!!
Been waiting for this video. Keep up the great work
Always interesting to see how other people do things, I've turned one before using a 4 jaw chuck in the head and tailstock. Offset each side equally using dial indicators
I'd love to be a toothbrush salesman in your town Donn! hahaha! great video keep em coming mate. :)
😁
They do make wedges for bolting through channel iron. I used thousands of them in steel buildings and on crushers we rebuilt for the gold mines here in S.D.
I can see why these cost thousands of dollars. Fantastic job !
You can use a centre in the 3 jaw and tack a drive dog to the shaft rather than try to offset in the 3 jaw. Your end result looked good though!
Not sure of the English word for it. "Square Taper Washer for U-Sections 14%"
We use them a lot
De gir mening hvis du trenger mange av dem, men for to stykker er tilnærmingen hans også bra.
They are called "hillside washers", available through most fastener and industrial suppliers
The first thing I thought was wether the offset in that cam would be enough. You said the same thing just as I was thinking it. Looks friggin awesome, though....just like always.

A cup of coffee and Donndiy, now that's a Good morning

Nice work but did you know that tapered washers are available for bolting to channels and I beams?

nice job!
I see the Makita reps listened. Congrats on the cordless driver😝 Hope it was sponsored
Nope, still not sponsored by them. 🤔
Man I’ve been wondering how you made that cam absolutely brilliant
Awesome work👍👌
You one clever lad , indeed...been learnin , studyin , and buildin....now you gonna get your just deserts....crushed rock ...!! Lol
Awesome as usual but one question will the cam shaft bearings have a cover? Enjoyed👍👍
Bearings will have a cover. 👍
Great work!
May I ask You about the difference in the eccentric? How many milimeters difference between the smaller and the bigger size?
Brilliant
Pidid vist rahakotti kergemaks tegema, ega need laagrid polnud odavad! 👍👍👍
Väga hullu ei olnudki. 👍
11:00 I'd feel better with more radius on the transition from the bearing to the cam. 13:20 Looks like you mitigated it by tapering the cam side. Should give you a shot for success.
Like a GLOVE...😌
Would it even be a Donn Diy video without the oiling toothbrush😎
Nice turning. How did you determine the offset or was it in some plan for such a crusher? Project looks great and I will certainly watch for the rocks to crush... Thumbs Up!
Nice work. Great!
It WILL be a success! 👌🏻
How much is the 'throw' ? 10mm ? 1 side, so total movement 20mm ?
Amazing project bro 💪👌👌👌
Merci
Nice job, I would have kept both center holes though!
Nice idea on the adapter for the holesaws! I’m going to copy that
@0:17 Was the pun intended? "These have to be beefy to withstand the "crushing" forces."
Clever. Very clever. ;-)
Nice 😶
Beautiful !
Bravo 💪👏👏
💪💪💪

That super badass I never knew that's how they did that I always wondered
Healthy, my friend🤝as always at the highest level, autumn is interesting to watch,and hands and head work 💪 😉 👍 👍 👍
I wonder if those bearings will take the pounding or if bronze bushings would be better. The load is more spread out on a bushing. I suppose we'll know soon enough.
And how does a guy keep his bearings clean?

Was that a mighty car mods reference? In the bin!
9:42 so the shaft eccentricity is 10mm? The sides are 60mm diameter and the inner part 70mm, right?
Very good.
Very cool!
Are you going to counter balance that shaft ?? It will vibrate itself to pieces if you dont
So question. I hope you are not going the let the cam run against the back of the crusher plate right ?? Are you going to use rollers perhaps for the cam to run against? Will you install springs to keep the plate pressed onto the cam ?? It will clatter if you don't. Will you use a flywheel for the camshaft ??

I hope you have something planned for the bottom pivot points on the moving plate . Dust and grit will eat away on it if you are leaving it sitting in the slots without any support with bearings or such
What is the offset measurement you used to create your shaft? I’m shopping for bearing and trying to figure out what the throw of my plate should be.
