Fantastic job. Your Pa would have been so proud of you, having been a sheet metal worker/ blacksmith himself. Goes to show a vision with real determination always pays off !!!
Thanks heaps John! Good luck with your build. If your build is roughly the same size as mine, go a 30mm throw on your eccentric shaft instead of a 20mm throw like mine and aim for 250-300rpm and she will be a bloody ripper! Cheers 🍻
Thank you Toby. Couldn't believe how well it turned out! 900kg/hr is bloody fantastic and will make my whole process sooooo much easier. Thanks for tuning in also 😁
Well done mate, good to see a build that most of us are able to complete without fancy hi tech tools. Ya got to be happy with that. I hope it gives you many hours of use and thanks for sharing.
That was the aim Scott, just to show that anyone can make one reasonably cheap with basic tools. I'm absolutely stoked at how well this one works. Will be interesting to see if I run into any problems with it over time. As it stands now, It seems to be super strong and reliable. Perfect for the small scale guys like us. Thanks for tuning in once again mate. 🍻🍻🍻

I just saw that BlackLabel! Thank you so much. You will be happy to know I intend to run competitions on my Patreon soon to show my appreciation to everyone that's helping me on my journey to becoming "The Goldman". I'm hoping to do roughly 1 gram of gold per month in random draws. Could be a nugget, fine gold in a vial, buttons from hard rock mining etc. Will also be doing random draws for paydirts rock samples! Thanks once again Oliver. 😁
Looks great man. I would add some rebar to the plates on each side but offset them. That way as time goes, you're just wearing the rebar down, plus they'll have more grab for grinding the rock down.
Thanks Andrew! I started with the flat plate because some of the other flat plate jaws I've used seem to get a smaller and faster crush than the typical corrugated jaw designs. I think rebar would be essential if my ore was really hard though, I can always add it later if need be, but so far it works amazing as is and I expect the Bis400 wear plates to last a very very long time. We will just have to wait and see exactly how long they last though.
Areet man. Loving the build 👍 I've always wanted to make one too since seeing the price of just a tiny one and this is really high quality. Just a thought about keeping the batteries cool. You could make a thing that holds Ice inside like a flask that wraps around the batteries. Never thought about it being a big problem before in hot places but I see now. Or make a mini freezer to wrap around. Where there's a will there's a way! 👍❤️💛💚
Thank you my Rasta brother! I had been waiting patiently for years for the right sized jaw to come up for sale at the right price and it just never happened. So bugger it, let's make our own and make it as basic and strong as possible so hopefully other can do the same. I think it would be sensible to just use the little milwaukee for smaller jobs in future, batteries don't like copping the beating that I gave to them over those few days 🤣. It's OK though. Still in warranty 😉
nice build sonny Jim .....just a little more throw and you are good to go .... seen a lot of people try to build their own and this one was pretty good. .... now lets see what is in all the beautiful ore
Thanks Jeeffffffffff. I would certainly go a 30mm throw if I build another one in future roughly this size. But I was amazed how well it worked as is. Especially happy that I didn't have to add anything to the jaw faces. Having 2 flat surfaces means I can close it right up if need be. Yeeeehhhawwwww buddy!
Haha thanks JM! A lot of my equipment has been kindly given to me or sold to me cheap by old fellas of the game. One day, when I'm worn out and ready to slow down I hope to pass all this gear on to some other young fella with passion and drive for gold mining also.

Great job, looking to do something similar. I'll be using a couple of engine flywheels for kinetic energy and powering it with me ol lister Cs diesel engine.
Thanks Shan! I'm still brainstorming about how to approach to setup as a whole. But yes, the general idea will be to either let gravity do the work or have a conveyor lift the ore from ground level up into a hopper above the impact mill that will incorporate a vibratory feeder so I can perfectly set the pace of the whole plant. I'm hoping to simply feed the jaw crusher 250kg at a time to fill the feed hopper. Then let the rest happen automatically so I can walk away and do other things while it runs 😁
Very nice! I like the dedication of working into the late night. Who made the eccentric for you? That is probably the most limiting factor of this type of build!
Thanks mate! Theres not enough hours of daylight to spend on all my little projects, so I've got an excellent headlamp 😁. Friends of mine who own BluArc Enginnering here in eastern Vic turned up the Eccentric for me on the lathe, I just drew them up a dodgy drawing of what I needed and they knocked it up for me very easily. Need to get myself a lathe. The possibilities are limitless then.
@@mikemullenix6956 Yes the eccentric shaft was the one bit I couldn't do myself. But any engineering place will be able to make one up for you pretty cheap. 👌
It wasn't too hard, just very slow given the basic tools. So the reduction box is 6:1, the driver pulley is 63mm and the driven is a 112mm. So roughly 250rpm at the eccentric. Cheers mate!
That would have been good to know before I spent 34 5 inch cut off wheels 🤣. Nah it's OK. I enjoy to meticulous labour. I'll remember that for next time though 😉.
incredible build scripped to the end to lazy to see how it was built until seeing the final results. Going to have to watch hole video now that is very impressive. just subscribed what do u use for finishing the mill? or are you still building? you building a shaker table? I'd have to watch that video to lol. I have a past producer lode mine here in the states Lovelock Nevada got lucky with a auction 5 Miles from my house 4-6 foot ball mill excellent condition I was the only person new what it was so I picked it up just a tad under what it's worth in scrap metal. There is a old jaw crusher that was used in 1940 on the mine still anyone know the chances of it working again? any thoughts is appreciated.
I've seen older crushers come back to life! So 1940s would certainly be repairable brother. After feeding the ore into the jaw crusher, it then goes through my impact mill and then ball mill before being gravity separated. Have recently acquired a shaker table to add to the plant, just haven't gotten around to fixing it up and installing it yet. Hopefully soon! My recovery will be much much better with the shaker as opposed to a sluice
Bloody sensational vid! Been waiting on something like this for years to help with the primary crusher build. So witht the cam you would run with 15 mm instead of 10 mm? You based in vic what was the name of the company id like to follow this build to the tee. Cheers brother.
Thanks heaps Timeis Now! Yes if I were to do it again I would go for a 15mm difference in the eccentric. The 10mm I did works amazing for my setup, but that little bit of extra throw would work even better! I am based in Vic yes, which company are you referring to though sorry?
Haha he's real champion old Morgan. Mind you, nearly 9 years of hunting and mining have taken its toll on his hearing. So he would likely sleep through an earthquake 🤣
Specifications aren't all that relevant in this case seen as I used scrap steel to build it. Anybody can build one with similar steel they find with different dimensions to suit their needs 😁.
Ill add one eventually Steven, I'm just still deciding what I have laying around that would work best. I think the main thing I would want out of a flywheel is to balance the whole unit a bit better and remove a little bit of the vibration though. I just don't want too much excess energy to back feed the reduction box when I turn it off. 🤔
Hey, you made a great job of the jaw crusher, hope you don't mind I'm gonna copy everything you did😁 might make the opening 200mm at the top for a bit bigger rock. Just wondering what hp your engine is and did you buy a separate reduction box and bolt it on or did the engine have it on already? Cheers from Donegal in Ireland🍻
Sounds great mate! Best of luck with your build. I've made some more mods to the Jaw crusher now, including 2x old brake rotors welded together with a 30mm taper lock pully and bush welded in the middle. That turned an already very capable crusher into an incredibly capable crusher. Nothing can stop it now! The old Honda G300 is 7hp and had the reduction box fitted to it from factory. They still have the option of fitted reduction boxes when purchasing new today. 👍🏼👍🏼
Good job sir, I like your own idea, will you teach me how to make it, I want to build one for my self, I'm an iron and metal welder, thanks, and God bless you
Mr Karl really you have grate experience about making jaw crushers smartly. I want to prepare one like this for gold minning project in Hargeisa so may you help me for further more indications about that?
Bearings have held up no problems at all Richard. I've put quite a few tonnes through the little Jaw crusher now and it's been bloody fantastic. Well and truly exceeded my expectations. I have made some minor changes to things also though. I will upload a review video of the Jaw soon, detailing changes and better ideas for others to try. Thats a good idea mate, even just a little welded plate behind the bearings each side would be very handy. That would remove the slop from the bolt holes. I have the bearings pushed all the way back towards the motor for this reason, but little positioning plates behind the bearings would be much better. 👍🏿👍🏿
Ill have to try that one day mate. My single phase genny is great for welding up to 10mm roughly. The 3 phase genny up at the plant can't produce the same power on one leg though unfortunately.
The desired throw depends on the power you've got to drive the machine. For my small engine and reduction box, the 10mm is fine. I don't think I could go to 15mm without it bogging down too much. 12.5mm would be perfect. The pulleys were originally 63mm and 112mm. But I changed that later on, made both bigger, but the same ratio. Simply to give the belt more surface area to grip on. The 63mm didn't have the surface area I needed. Your machine may be different of course, depending on engine speed and the reduction box ratio. My reduction box is 6:1. The ideal speed at the eccentric is approx 250rpm, so just aim for that, and you will be all sweet mate.
@@TheGoldmansChannel while doing research I found motors without 15HP reduction. There are 2:1 reducers, no other models. Without reduction the size of the driven pulley would be enormous.
The current Honda model code for the 6:1 reduction box is HX. Have a google for GX270-HX8 and see what that comes up with mate. Without the reduction box there are 2 options, a very large driven pulley, or a secondary Shaft mounted between more bearings. That way you can have a small driver on the motor, to a larger driven on the second shaft, which then has a smaller driver pulley next to it, which then in turn goes to a larger driven pulley on the Jaw crusher itself. Essentially making yourself a reduction box, with just 2x extra pulleys, an extra shaft and extra bearings. The reduction shaft should be kept as short as possible if only using a bearing on each end of it, or if it needs to be longer, add a 3rd bearing between the 2 pulleys in the middle somewhere. Not a complicated job, just requires some extra bits and pieces. 😊
Very cool mate, I hope you upload a video of the finished product for me to see! I'm currently thinking of making a mini jaw crusher and impact mill for portability.
Good job, I’m building one that’s modeled on yours. So did the angel of the jaw work well and if so what was the degree ? Also were yer bearings roller or ball and what size were they ? I really like this simple design ! I’m gonna copy this
Thanks Joe! The angles all worked great, top of the jaw was approx 100mm opening, the bottom was set to about 20mm gap. Ball bearings for the bearings, 40mm on the centre of the eccentric, 30mm on either side.
I drew up my shaft design and gave it to my buddy who has an engineering shop. He turned it up on the lathe. I assume he started with the centre diameter and then offset the jaws to throw an eccentric movement and cut down each side to specs from there. I've got a video of it on the lathe if you want me to email it to you? Cheers!
500mm over-all length. The eccentric centre part is 40mm diameter and 180mm long from the centre of the work. Each 30mm diameter side of the shaft makes up the other 320mm. Hope that's helps
This is awesome, I have all this steel around to build one but having trouble finding eccentric shafts and bearings to match. Any pointer where I can get some?
The eccentric is really something that will need to be manufactured by your local engineering/fabrication shop Beefer. Or if you have any friends that own a metal lathe, go visit them and draw up some designs. Bearings are about the easiest bit usually, readily available online. But if you get stuck, ask the fabrication shop to source them for you when they do the Eccentric 😁
I went with a 10mm difference, which more or less gives me a 20mm throw. 30mm diameter either side of the 40mm centre. I would go with a 15mm difference if I did it again, giving it a 30mm throw. I wasn't confident my engine was going to deliver the power it needed at that time. But in retrospect, it would have handled it fine with the pulley ratios I'm currently using.
If I want it finer I can just adjust the 2 bolts in a bit further to close up the bottom of the jaw. At this stage though, the output size suits my setup just fine. The impact mill can take 40mm chunks of rock and the rock coming out of the jaw is less that 20mm. Perfect 😁
So is Oxy acetaline hard to get there ? A "Victor Wrench" (cutting torch) would save you a lot $$$ on cut off wheels . An if it is a chain saw concrete type "Cut Off" with good 16"/18" wheels . You may need to make the guard...
Good morning sir, from nigeria, first I'm so happy to see that you replied to my post, please sir, can you write down for me the materials needed for this job, don't be angry with me sir , size plates and bars and others
No plan mate. Seen as it was mostly made out of recycled steel I just designed it based on the width of the C channel steel. Unless people purchased the same steel off the shelf my measurements would be useless to them. Scrap is best 😁
I noticed that you didn't bother to bevel any of the edges of those pieces to get maximum weld penetration. That might come back to haunt you, depending on how hard and frequent you use it. On the other hand, it looks to work quite well. That is absolutely a win on your project design. 🤔✌️😎
May just have been tricky to see in the video, but I ground out almost every edge and join that required welding. Got great penetration on them. Mind you, welding isn't one of my best skills, I'm still very new to it! So far so good on the structural integrity of the jaw crusher. I use it heaps and have given it a really hard time and it so far hasn't given me any trouble at all. It just keeps munching! 😁
I guess i missed it then, but all good because the only person you need to please, is yourself. And again, it appeared to be working exactly the way you designed it to. I'm a prospector/miner myself and have a couple claims over here in the US. I was watching your video to educate myself with the equipment. ✌️😎
@aumetalmental8403 Fortunate that I only need to please myself with my engineering skills. I don't believe they're quite up to scratch to make or sell for others. Something would go flying and I'd end up with a law suit 🤣. Cheers mate, I hope your projects over there in the US pan out really well for you
Thank you Tyler, I'm super happy with how the build turned out. Ive only made a few little changes to it since the build. (Switched to B section pulleys and belts, slightly larger in the driver pulley, slightly smaller in the driven pulley). Just to give it more surface area on the driven pulley to get belt grip. Something to keep in mind if you build your own. The channel was 180x75mm.
I just drew it up on paper and got one of my engineering friends with a Lathe to turn it up for me. 500mm long. Centre offset diameter is 40mm and 180mm wide. Each centred side is 30mm in diameter.
Howdy John, the eccentric shaft I had turned up on a lathe was 500mm long X 30mm diameter either side of the 40mm diameter X 180mm long eccentric. Cheers!
Sounds good John, give yourself a little bit more throw on that Eccentric shaft too if you can. If you've got 60mm bar cut the sides down to 45mm diameter. The 20mm throw on mine is good, but it could use 25-30mm throw. That would have made it much better 👍🏿
@@jansynowiec Because it will work a little better with more throw on the jaw. Mine moves 20mm when rotating. But 25-30mm movement would have worked better. :)
I used 4 pillow block bearing housings with sealed ball bearings for this project. The exact ones you will need will depend on the size of your shafts. Best to contact a local industrial supplier for common sizes and such for your own project. Cheers!
Seen as you asked nicely, the 30mm pillow blocks are P206, the 40mm pillow blocks are P208. The bearing codes for them I can't quite see though sorry. But that should be enough for you anyway. Cheers!
Hey Bradley. I'd be happy to look over your plans if you email them over to me at thegoldmanschannel@gmail.com I'm no expert, but I may be able to identify some issues or areas for improvement?
No I don't need any help these are original speck drawings.just sold my other one which I didn't think I needed but now I do, this was to see if you wanted them maybe make your own?
Love the videos keep it up. But you my friend have given me some good ideas. Dodgey designs make it better because you built it. So you know how to fix it properly. I like the idea in this video.
Cheers Mick. How long ago did you find my channel? Lurking in the background I see 🤣. Got a flywheel in mind, however it's suprising how well it goes without it! Would take some load off the reduction box though. Yeaahhh buddyyyy
@@michaelljiljak5926 he's definitely slowing down a bit. 9 this year already! Might have to weld some fold down steps onto the rear of the patrol soon lol

Bloody sensational vid! Been waiting on something like this for years to help with the primary crusher build. So witht the cam you would run with 15 mm instead of 10 mm? You based in vic what was the name of the company id like to follow this build to the tee. Cheers brother.
Thanks heaps Timeis Now! Yes if I were to do it again I would go for a 15mm difference in the eccentric. The 10mm I did works amazing for my setup, but that little bit of extra throw would work even better! I am based in Vic yes, which company are you referring to though sorry?
I love how your dog slept through those cuts ... My dogs would've headed to the hills to hide.
Haha he's real champion old Morgan. Mind you, nearly 9 years of hunting and mining have taken its toll on his hearing. So he would likely sleep through an earthquake 🤣
@@TheGoldmansChannel lol 😆
Nicely done
Thanks Matt! It well and truly exceeded my expectations! Very happy
Nice very nice love it
Doo ok u have the speciations on the material n tools u used in case someone wants to reproduce all your step ? Oh 😥
Specifications aren't all that relevant in this case seen as I used scrap steel to build it. Anybody can build one with similar steel they find with different dimensions to suit their needs 😁.
If you reckon you need a bit more torque, chuck a flywheel on the shaft .
Ill add one eventually Steven, I'm just still deciding what I have laying around that would work best. I think the main thing I would want out of a flywheel is to balance the whole unit a bit better and remove a little bit of the vibration though. I just don't want too much excess energy to back feed the reduction box when I turn it off. 🤔
Hey, you made a great job of the jaw crusher, hope you don't mind I'm gonna copy everything you did😁 might make the opening 200mm at the top for a bit bigger rock. Just wondering what hp your engine is and did you buy a separate reduction box and bolt it on or did the engine have it on already? Cheers from Donegal in Ireland🍻
Sounds great mate! Best of luck with your build. I've made some more mods to the Jaw crusher now, including 2x old brake rotors welded together with a 30mm taper lock pully and bush welded in the middle. That turned an already very capable crusher into an incredibly capable crusher. Nothing can stop it now!
The old Honda G300 is 7hp and had the reduction box fitted to it from factory. They still have the option of fitted reduction boxes when purchasing new today. 👍🏼👍🏼
Good job sir, I like your own idea, will you teach me how to make it, I want to build one for my self, I'm an iron and metal welder, thanks, and God bless you
Good job 👏 man growser bar for dozer for teeth biz as well 350
Mr Karl really you have grate experience about making jaw crushers smartly. I want to prepare one like this for gold minning project in Hargeisa so may you help me for further more indications about that?
Check out the latest vid for additional info on the Jaw Crusher build mate. Hopefully that will give you the extra info you need. Cheers 👍🏿
@@TheGoldmansChannel okay thank you engineer for sincere advice
Have the bearings lasted? Also would a couple 2 piece clamps beside the bearings help hold the shaft with all the vibration.
Bearings have held up no problems at all Richard. I've put quite a few tonnes through the little Jaw crusher now and it's been bloody fantastic. Well and truly exceeded my expectations. I have made some minor changes to things also though. I will upload a review video of the Jaw soon, detailing changes and better ideas for others to try.
Thats a good idea mate, even just a little welded plate behind the bearings each side would be very handy. That would remove the slop from the bolt holes. I have the bearings pushed all the way back towards the motor for this reason, but little positioning plates behind the bearings would be much better. 👍🏿👍🏿
Use 3 decent sized truck batteries in series. You'll get a nice strong weld. Just charge them up now and again.
Ill have to try that one day mate. My single phase genny is great for welding up to 10mm roughly. The 3 phase genny up at the plant can't produce the same power on one leg though unfortunately.
For the eccentric, do you think we should put 15mm of difference or is 10 enough? So what is the diameter of the final driven pulley? Thank’s.
The desired throw depends on the power you've got to drive the machine. For my small engine and reduction box, the 10mm is fine. I don't think I could go to 15mm without it bogging down too much. 12.5mm would be perfect.
The pulleys were originally 63mm and 112mm. But I changed that later on, made both bigger, but the same ratio. Simply to give the belt more surface area to grip on. The 63mm didn't have the surface area I needed.
Your machine may be different of course, depending on engine speed and the reduction box ratio. My reduction box is 6:1. The ideal speed at the eccentric is approx 250rpm, so just aim for that, and you will be all sweet mate.
@@TheGoldmansChannel while doing research I found motors without 15HP reduction. There are 2:1 reducers, no other models. Without reduction the size of the driven pulley would be enormous.
The current Honda model code for the 6:1 reduction box is HX. Have a google for GX270-HX8 and see what that comes up with mate. Without the reduction box there are 2 options, a very large driven pulley, or a secondary Shaft mounted between more bearings. That way you can have a small driver on the motor, to a larger driven on the second shaft, which then has a smaller driver pulley next to it, which then in turn goes to a larger driven pulley on the Jaw crusher itself. Essentially making yourself a reduction box, with just 2x extra pulleys, an extra shaft and extra bearings. The reduction shaft should be kept as short as possible if only using a bearing on each end of it, or if it needs to be longer, add a 3rd bearing between the 2 pulleys in the middle somewhere.
Not a complicated job, just requires some extra bits and pieces. 😊
Well done I like it
Thanks Jamie-lee! Really glad you like it 😊
Very good work. :-)
Thanks Thomas! 😁
Hi Mate, cracka vid, What was the size of the C Chanel?
Thanks mate! The channel is 180x75 👍🏿👍🏿👍🏿
I’m going to try and make one for my self but mine will be a hand crank version as I’ll be using it to crush charcoal
Very cool mate, I hope you upload a video of the finished product for me to see! I'm currently thinking of making a mini jaw crusher and impact mill for portability.
Good. I'm from Tashkent
Good job, I’m building one that’s modeled on yours. So did the angel of the jaw work well and if so what was the degree ? Also were yer bearings roller or ball and what size were they ? I really like this simple design ! I’m gonna copy this
Thanks Joe! The angles all worked great, top of the jaw was approx 100mm opening, the bottom was set to about 20mm gap. Ball bearings for the bearings, 40mm on the centre of the eccentric, 30mm on either side.
So sorry to bother you again but where did you get yer pulleys ?
Its no bother Joe 👍🏼. In my case, I purchase them from an industrial supplier. AIS industrial supplies, here in Eastern Victoria.
Great build.
*high five*
🤚👍🏿
this is awesome, thanks for sharing. I'm going to build one for making stone for the driveway
Great idea Chonky, would be super handy simply mounted on the back of the vehicle or on its own little trailer. Portable quarry! 😎
Mate how did you design the shaft ? As in in concentric angle ? Thanks
I drew up my shaft design and gave it to my buddy who has an engineering shop. He turned it up on the lathe. I assume he started with the centre diameter and then offset the jaws to throw an eccentric movement and cut down each side to specs from there. I've got a video of it on the lathe if you want me to email it to you? Cheers!
Hello! What are the excenter shaft's measurements?
Tbanks for the answers
500mm over-all length. The eccentric centre part is 40mm diameter and 180mm long from the centre of the work. Each 30mm diameter side of the shaft makes up the other 320mm. Hope that's helps
This is awesome, I have all this steel around to build one but having trouble finding eccentric shafts and bearings to match. Any pointer where I can get some?
The eccentric is really something that will need to be manufactured by your local engineering/fabrication shop Beefer. Or if you have any friends that own a metal lathe, go visit them and draw up some designs. Bearings are about the easiest bit usually, readily available online. But if you get stuck, ask the fabrication shop to source them for you when they do the Eccentric 😁
What is the offset measure that you used on your shaft?
I went with a 10mm difference, which more or less gives me a 20mm throw. 30mm diameter either side of the 40mm centre. I would go with a 15mm difference if I did it again, giving it a 30mm throw. I wasn't confident my engine was going to deliver the power it needed at that time. But in retrospect, it would have handled it fine with the pulley ratios I'm currently using.
Sounds good I’m going to try bearings with 13mm difference I think
Sounds great Mark 👍🏿 Get into it mate 👍🏿
Background noises in night like a VLF auroral chorus sounds.
BADASS!
Can you tell me the offset on the cam? outside pillow block size to inside bearings?
Sure can, that was in the video though. 40mm ø centre section, with 30mm ø either side of it. Cheers mate 👍🏿
Any way you could attach a >quick change< small reducer so that you could send it all through again to get if finer?
If I want it finer I can just adjust the 2 bolts in a bit further to close up the bottom of the jaw. At this stage though, the output size suits my setup just fine. The impact mill can take 40mm chunks of rock and the rock coming out of the jaw is less that 20mm. Perfect 😁
So is Oxy acetaline hard to get there ?
A "Victor Wrench" (cutting torch) would save you a lot $$$ on cut off wheels .
An if it is a chain saw concrete type
"Cut Off" with good 16"/18" wheels .
You may need to make the guard...
Easy to get here, just haven't bought myself an oxy kit yet. It's on the wishlist though!
Please sir I like your hand work, will you teach me, I want to build one for my self, I'm a welder, thanks and God bless you
What extra info do you need Jacob?
Good morning sir, from nigeria, first I'm so happy to see that you replied to my post, please sir, can you write down for me the materials needed for this job, don't be angry with me sir , size plates and bars and others
Do you have a drawn up plan for the sizes anywhere?
No plan mate. Seen as it was mostly made out of recycled steel I just designed it based on the width of the C channel steel. Unless people purchased the same steel off the shelf my measurements would be useless to them. Scrap is best 😁
Hi, great work! can you tell me the diameter of each side of the shaft and also at the eccentric please ?
30mm either side of the 40mm eccentric mate. Good luck with your build!
Thank’s you 👏🏻
No worries mate 👍🏼
Gotta love the cheek poker 6000
I noticed that you didn't bother to bevel any of the edges of those pieces to get maximum weld penetration. That might come back to haunt you, depending on how hard and frequent you use it. On the other hand, it looks to work quite well. That is absolutely a win on your project design. 🤔✌️😎
May just have been tricky to see in the video, but I ground out almost every edge and join that required welding. Got great penetration on them. Mind you, welding isn't one of my best skills, I'm still very new to it!
So far so good on the structural integrity of the jaw crusher. I use it heaps and have given it a really hard time and it so far hasn't given me any trouble at all. It just keeps munching! 😁
I guess i missed it then, but all good because the only person you need to please, is yourself. And again, it appeared to be working exactly the way you designed it to. I'm a prospector/miner myself and have a couple claims over here in the US. I was watching your video to educate myself with the equipment. ✌️😎
@aumetalmental8403 Fortunate that I only need to please myself with my engineering skills. I don't believe they're quite up to scratch to make or sell for others. Something would go flying and I'd end up with a law suit 🤣. Cheers mate, I hope your projects over there in the US pan out really well for you
Hello, what is the cost of this work if the aperture is 60.40
We’ll built! What size of channel iron are you using?
Thank you Tyler, I'm super happy with how the build turned out. Ive only made a few little changes to it since the build.
(Switched to B section pulleys and belts, slightly larger in the driver pulley, slightly smaller in the driven pulley). Just to give it more surface area on the driven pulley to get belt grip. Something to keep in mind if you build your own.
The channel was 180x75mm.
@@TheGoldmansChannel Thanks for the info! Always looking forward to your videos!
No problem at all mate. Glad you enjoy my occasional videos. I really appreciate the support 🤟🏿
Hey boss, What size engine are you using on your crusher?
Morning Tyler. The old Honda engine used on the Jaw Crusher is a G300. So 7hp. 👍🏼
Where'd you get that eccentric shaft?
I just drew it up on paper and got one of my engineering friends with a Lathe to turn it up for me. 500mm long. Centre offset diameter is 40mm and 180mm wide. Each centred side is 30mm in diameter.
which camera you shot this video with and where it is attache?
Just an old GoPro 7, head mounted or on a tripod 👍🏿👍🏿
@@TheGoldmansChannel thanks. 👍
No probs at all 👍🏿
Those blue bearing blocks are not going to last long. You need steel housing and heavier bearings
Ill look into that, thanks mate 👍🏿
Do you have a 9inch grinder????
No I don't, but im getting bloody handy with the old 5 inch grinder! 😆
F32432 briliant
What size channel iron did you use
180x75mm Joe 👍🏿
how thick is that steel?
Flange Thickness: ? Web Thickness: ?
The C section is 6mm through the centre, with 10mm sides.
What's was the size of the Shaft??? Best regards John 😊
Howdy John, the eccentric shaft I had turned up on a lathe was 500mm long X 30mm diameter either side of the 40mm diameter X 180mm long eccentric. Cheers!
@@TheGoldmansChannel I will make from 60 mm and drop to 50 mm. Motor 10-15 hp
Sounds good John, give yourself a little bit more throw on that Eccentric shaft too if you can. If you've got 60mm bar cut the sides down to 45mm diameter.
The 20mm throw on mine is good, but it could use 25-30mm throw. That would have made it much better 👍🏿
@@TheGoldmansChannel why you recommend to give more?
@@jansynowiec Because it will work a little better with more throw on the jaw. Mine moves 20mm when rotating. But 25-30mm movement would have worked better. :)
What is bearing type used?
I used 4 pillow block bearing housings with sealed ball bearings for this project. The exact ones you will need will depend on the size of your shafts. Best to contact a local industrial supplier for common sizes and such for your own project. Cheers!
Please tell me number of bearing
Ucf 208 or other number
Seen as you asked nicely, the 30mm pillow blocks are P206, the 40mm pillow blocks are P208. The bearing codes for them I can't quite see though sorry. But that should be enough for you anyway. Cheers!
Bendiciones 🙏 que buena
Dont push so hard let the weight of the grinder and cutting wheel do its job.
Come show me how it's done Edward. I've got lots of big thick steel here that needs cutting up 😝
Yeh nah ya cant have your batterys take up beer space. Better to not even do the job in that case.
This man gets it. Priorities right!? 😆
I hate those cup sanders. They want to take a chunk out of you.
They really do! I'm very cautious even when just looking at it 🤣
Hey Karl building a Gemini table at the moment how could I get in touch too send you plans
Hey Bradley. I'd be happy to look over your plans if you email them over to me at thegoldmanschannel@gmail.com

Well look at you...😉.
Email sent.
Love the videos keep it up. But you my friend have given me some good ideas. Dodgey designs make it better because you built it. So you know how to fix it properly.
I like the idea in this video.
Thanks James! Dodgy is best. I love anything home made using what's available 😎
Отличный аппарат! 👍☺️
Good job. Looks better than my china one.
Get yourself a pooey flywheel on it to give it some reciprocating mass.
Cheers Mick. How long ago did you find my channel? Lurking in the background I see 🤣.
Got a flywheel in mind, however it's suprising how well it goes without it! Would take some load off the reduction box though. Yeaahhh buddyyyy
Ages ago haha think ive watched most vids.. morgs doesnt look like his aged at all!! Yeah flywheel = free power haha.
