- In our on going mission to be fully self sufficient it is time to get fencing done and start keeping animals. I just cant bring myself to buy something that i can make myself so i set about making this post driver and it works great!
Add a bit of pipe that fits around the post on the underside of the striker plate, that will keep the post in place, and inflict minimal damage to it in the pounding process. Keep us...uh, posted.
If no pipe is available, just a square of plates welded on, although it does limit the size of post, straining posts being larger. I was thinking just run the stick welder across the plate to form ridges.
if you make the bit of pipe on a slip on its own plate which you can slide onto the striker plate you can make new plates for each type of post you need in the future without having to remake striker plate each time
@@stetee4238 also, in addition to the attached pipe striker plate. If he welds say 2" x 4-6" solid round to the centre of the bottom of the impact weight, and on the top of the striker plate. That will centralise the impact strike zone. As the plates are at present! The strike zone is more spread out.
Posted....nice😁
I am a retired mechanical engineer. I must congratulate you on this achievement of what you have manufactured from scratch to fully functioning completion. It is simple but efficient well done I say
Man makes big hammer. Man makes people happy. Thank you hammer man.
I'm a 49 yo woman from Australia, and you are inspiring. I've learnt so much from your Videos. Thank you.
This isn't a dating site
You deserve every bit of praise you get from your audience! I am in awe of your reasoning skills and make it happen attitude along with being able to do everything!!!! Everything.
Kris, I don't think there is anything you can not do. I love the weekend because there is always a video from you. Best wishes to you and Dot. 🙂🇺🇸
Kris, you are one amazing man! All that confidence wrapped up in a reserved quiet spirit. And can construct a harp that sounds angelic. Enjoy the life that you both are building together. You are living a lot of us old timers’ Dream.
Kris , I've been a mechanical engineer for 18 years and I must say this is verrry impressive considering you don't even have a machine shop.
Also little tip why you suffered porosity in weld " crank up your argon to about 8 litre per minute " also " take the coating off the steel using scotch bright or emery cloth "
Also sounds the generator is sagging as you start the bead. Start about 1/2" forward of where you want, then back drag to the start and weld over your strike point.
Also in the tight spots a good trick is to bend the end of the electrode right at the stinger. Then you can rotate the stinger and the rod to get all kinds of crazy angles to reach.
Only just realised the power loss from generator.
That's due to the upslope on the tig welder drawing too much.
Lower the amps on your up slope slightly also.
You should be able to achieve the bead after at around 60-80 amp
On the back of Russell's comment about the porosity maybe take a second or 2 with your argon pre and post flow. It might help. Great build by the way. Very, very impressive indeed. I don't need one, have a machine to drive one or have the land to use one but......I want one
Argon with arc welding? You must be some engineer.
@@bobsmith9329 funny guy you are. He is TIG welding . Do you even know different types of welding
Amazing Kris! I am afraid your kind are becoming more and more rare in this world
Well done sir. I'm all for the man, or woman who has the creativity and/or need to get out there and build something they need or want. You may not have the biggest or fanciest shop or equipment but by Jim you made it happen! You're an inspiration to others.
Another fabulous fabrication . Watching you install the first post was amazing & I had a Giant Smile throughout. Your post pounder is truly beautiful ❣❣👍👍
Make a good log splitter with right attachment.
Yeah 👍 small plate with two holes to bolt on with an axe head welded to it. Very quickly a log splitter
I thought the same
@@KrisHarbour And maybe some kinda shield so the log dont fly at ya
Jesus bud.!!!-never fail to impress Chris..your one industrious fellow Chris..nothing but RESPECT and GRATITUDE to you..for sharing your processes and thoughts from inception of your honest journeying
Kris, you're Amazing! I've been following you since you started the round house. You're so talented, and humble and nice! You and Dot are such great people. Best wishes in everything you do and God Bless you both!
Absolutely incredible! From scrap to a tool that will last a lifetime and save your back. One day I’ll make something like that.
I’m watching out of order. Not much for mechanical/engineering/electrical, but saw your fence post video and had to see how you made this.
Amazing as always
Kris, you are a brilliant young man who I am sure you will succeed in your aim to become self sufficient.
Kris I am amazed at how gifted and talented you are. I love the excitement you show when it does turn out good!
I have been watching your videos since the outdoor solar shower.
My favorite videos are the hydro series, but this is one of the coolest metal fab projects I have seen on TH-cam.
As for the porosity on your tig welds, you have to clean the mill scale back at least 1"(2.54 cm) from the edges of the weld zone on both sides of the joint.
Also shortening your tungsten stick out and putting up a simple wind break (tarp, or piece of plywood) will help when welding outside.
Well done, to have actually made something that you have never used before is a great achievement. Looking forward to seeing this being used.
check his latest video; its getting used again ;)
I can't believe you're not an engineer. What you are is amazing! You inspire us, sir. Keep up the good work.
Brilliant! I was about to look online for a post rammer but you've inspired me to build my own. Thanks mate!
i think its the same lots on all videos that dislike this, either they are bots or just not watching... WELL DONE KRIS! FRIKKIN WELL DONE!
Absolutely amazing!!! You make living in a field look easy my friend 🤟🏼
Man brother...you never cease to impress with your engineering skills.....BRAVO!
Using a screw top link for that sliding adjustment sleeve...just fantastic! Kris, I'm going to copy that for a belt tensioner if you don't mind..
Kris, I think your problems with porosity is from not cleaning the metal well enough prior to welding. The sparks you see coming off the welding pool are an indication of dirty metal which is a no no when tig welding. You must make it just as clean as when doing stainless, a wire wheel and a wipe with acetone should make it right for you in future. Cheers and love your channel, always get the happy on when I see your new posts. Take care, Bob
Just a suggestion as well that might increase the downward impact of the hammer would be the addition of a trip assembly to allow the hammer to lock over a catch on the slide when the lever is fully cocked and then to release when the hydraulic cylinder returns the lever to the neutral position. This would increase the hammer falling speed by removing the hydraulic cylinder resistance on the hammer slide. A small section of pipe just larger than the diameter of the posts welded to your bottom plate would keep the post from moving around during the placement and insertion. Looking good! Bob
That is the coolest thing I've ever seen. Now I am convinced that you can do anything.
Using that for the first time must have been soooo satisfying. Great work.
Seeing you so giddy is great
Great job, impressed by your creativity and engineering.
Kris that is brilliant. I'm always blown away by your abilities and what you've created.
Fantastic work! The small Kubota took my eye as I too love building stuff to add to my own (loader, digger, grader etc.). Great to see someone else shares the passion. Love to see what you're doing and thanks so much for sharing!
Kris do not add any type of grip to the bottom of the plate.. it will just shatter the top and cause it to rot faster. I build fence as a living. Your design is pretty nice. A bit complex for me yet should do the trick for your needs.
Couple of mods I would make to make it easy for you.
Move you lock pin about 6 inches above your line post. You do not need the weight way above for setting the post.
Mark with white paint your post height and stick to that height where the base sits flush with the ground. Do not adjust post height to be perfectly level across the top. Sorry these will be in inches.. If you have a 4 foot fence height then set post about 51 inches from ground, this allows for enough meat on the post to staple the fence too.. Add 3 inches for 3 foot fence and so on.
Make a proper corner. This is done with 8 foot post set to 51 inches and then mark 1/3 of the way down to set either a steel or wood cross brace about the same length as the corner post. 8 foot to 7 foot is just fine. Wire this together.. There are a number of videos that explain this.. Some are wrong while most are right.
Line post should be set about 1 rod apart or 16.5 feet. You can use a v shape walking measuring stick to mark out post.
Build all of your 3 post corner h braces and 2 post and any other brace first. If you are using sheep fence ( wire fence ) then get a roll of barb less double strand to make your fence line. wrap the wire around the base of the corner post and stretch it to the next brace and use a come along and wire holder tool to stretch the wire out.. Then sight it in.. Shake the wire by lifting it up and down to move it off the grass and it should line up in a nice straight line.. Then hold up a line post and the person sighing it in will tell you where to move it to be pretty darn close straight ... then lay the post on the wire after you have shaken and moved it in line. Longer stretches you will need to sight it in more times. Shorter ones you may be able to pick up the whole wire from end to end and sight it in. Then when you install your post keep them about 1 inch or so away from the wire and set in place.. You post pounder will set normal post as well, you may not need all spiked ones unless you have already bought them all.
Hi,yes he's got the posts already.Thanks for such clear instructions.
I would also like to point out that full strokes are not always needed. To set the post a half a dozen small strikes and some adjustments will line up the post then a few larger strikes and grow the strikes as you set the post. Doing this allows you to make adjustment as you need them. This also prevents the post from being driven at an angle. One can eye ball the levelness of the post.. trying to make each post level with a level is a lot of extra work. Not all post are going to be true while some will have curves on them. Trying to force the post will lead to busting some. At a cost of 15 dollars a post and breaking a few in every mile of fences adds up.
The posts will flex during each stoke. This is why you do not want to encase the post in to something, Doing so can lead to a shattered, split or even broken post... I have put in a lot of post and 100s of miles of fence.
You never cease to amaze me with your ingenuity.
I thought the same thing about the spikes on the plate to hold the post when I was watchin . . . Looks Good ! LIVIN life like this . . . Your doin your part for sure . . . Love them vibes . . . Its clear what a person needs and dosen't need when you watch this . Your a smart doood and you don't need me to tell you that but I felt like sayin .
Hello really enjoyed watching you build this....I built myself 1 too in 2012 to enable me to do my own fencing.... you have great skills... well done ....and all the best for the future 👍
Absolutely brilliant, Kris. Amazing.
Hello Kris! We are living in the north of Sweden and would like to build something similar. As you, we are self sufficient and our goal is to be FULLY self-sufficient. We appreciate your job and are looking forward to new clips. Best wishes from the North of Sweden
Great job. I have to say that I didn't know what you were building in the beginning of the video. That works great
I pounded about 80 of these in by hand a few years ago. I have to say I would have preferred this method!
I was doing it into very wet clay with one of those steel post bumpers and they did go in easy. Strained it with a ratchet strap and banged in some bracing.
Over the years a few have heaved up with drought in the summer and frost in the winter but they go back down if you hit them hard!
Waiting a whole week for new Kris Harbour video and when it comes out it really makes an afternoon :)
Excellent excellent .
I have spent many days diging holes. For posts .Great idea
You truly can make anything, awesome Kris and Dot.
Great work man! Yeah for sure you can make other attachments with that same set up... log splitter idea is a good one!
You can make things look great Kris! 👏👍👍👍💯💯💯
so entertaining to watch, incredible what men hands can do. And yes I was happy to see that it work't but also that you were going to protect your ears. Very impotant, I look at you with my nurse eyes also ;-). You must go to bed so pleased and fulfilled. I made a home with my friend with cob in 2017, little bit strow and a bit off donkey shit, It work't well for the fist layer. And doing that kind off labor was aposolutly the best thing I've ever done. Made me so happy. So keep safe and have fun!
I love that you can use your roof as a platform to work from.
Great Post Driver that you built! Excellent video.
What the hell of a machine...reminds somewhat of a guiolltine, but more useful...
:-D
A simple cut-off of some pipe, welded to the underside of the follower like a collar for the post should work...
Great build, I doesn't expect that much power...it's leverage, man!
:-D
Thx for the vid!
Kris the engineering and effort on this are absolutely fantastic! I throughly enjoyed watching. Please forgive the brief safety concern: I noticed in your test drive that the ram hits the slam plate just about at eye level. If a chunk of that concrete, dirt, whatever got between the two- there's a good chance the debris could shoot out into your eyes. I noticed you were looking for hearing protection during the video, but perhaps safety glasses too. Ok, enough of that... just sayin'. Awesome rig- massive high five!
Agreed 👍 I was up the top and just wanted to get the vid done. But your right both of them are needed to run it safely
@@KrisHarbour A light rubber/tarp apron built around the slam plate like a curtain can help stop debris pinging out like a projectile and also a little bit glued onto the slam plate can slightly deaden sound.
Yup its eye level - I cringed every time it came down - glad to see you're going to wear protection.
For the odd post on the farm here we just use the front bucket (if you have the float option) but for that many posts......
As always awesome resourcefulness sir- .....Nova Scotia, Canada
You sir are an inspiration!!! You could use the aluminium from a cut open can for spacers maybe?? Keep up the awesome work! 👌👏🏼
Magnificent bit of kit. With all that heavy rigging can't help but feel I'd want a hard hat on or something especially operating it so close when doing a lot of posts. All the best.
Another jaw-dropping design and build. I really cannot take enough hats off Kris; fantastic job. I am only slightly disappointed you didn't build your own tractor, but I guess you'll get to that when you have a spare 10 minutes, eh?
I thought you were going to make a post hole digger but made that. I'm impressed.
Well Done Chris didn't expect anything less from you, that machine would have cost a packet to have bought it.
Great vid always worth waiting for.
Cheers buddy.
Genius mate. Love this video. Can't wait to see the fence stretching. 💚👍
mate i loved watching that thing come together, amazing work. cheers
Very nice, your driver made quick work of that post.
I thought I had developed a superpower of seeing into the future when this appeared, but watching it for a second time made me realise why it was a re-upload.
It wouldn't be difficult to make a tool that can be fixed on the bottom of the weight and make it a log splitter as well.
Why was it reloaded?
wow ..amazed and eager to see your beautiful property filled with lovely animals. just WOW
Another great build by Kris.
Very good video Ive been looking for someone to finally show a build. Thank you for sharing 👍🇮🇪
Could you share the hydraulic cylinder spec please?
@@Teamotoring find out??
wow that is fantastic saved you a fortune making it your self well impressed
Good episode.
Nice paint job.
Another good video, as always impressed by your work, thanks for sharing, 😁
Nice pile driver. I always enjoy your videos.
Adding a layer or two of old carpet in between the weight and the slam plate might help reduce both the shock (and potential long-term damage) to the underside of the weight and your ear drums.
Good idea 👍
@@KrisHarbour You're welcome. 👌
The big boys use a thick 1 inch rubber mat on the slam plate to reduce the impact. Ear defenders are a must when post ramming and a good sense of timing too. ;)
@@filthy-hobbit A rubber mat costs. A piece of tyre tread would be just as good, plenty of old ones about, and its a form of recycling.
Fantastic backyard engineering! Loved this video!
Just watching 24th of June 2021
Homemade Post driver.Hope ghe rope doesn't brake or your wife is in line for a knocking.The role cage looks to far back to protect her.Great series hope you carry on your quest with the wife.
very clever. love watching your ingenuity at work
Quite impressive my friend ...Just makes me smile to see you make another successful project. Obviously you need ear muffs and eye protection other than that its brilliant job Kris.
So great job. Impressed. Greetings from France
By far my favourite TH-camr 👍
Really impressive build Kris, looking forward to seeing a video on its use. One friendly suggestion for a minor enhancement if I may. I would add painted white line measurements along the inside of the vertical shaft (and maybe paint the edge of the driving plate) to assist with driving heights for your posts as you'll need to have consistency in your fence posts. Start at 800mm and go in 50 or 100 mm increments up to 1500, 1800mm or 2000mm to cover all the standard post heights. I believe it would be easier than having to carry a measuring tape or template stick or whatever with you.
Easier to just mark the posts to required height!
@@tonygrimes13 I do not see how marking however many individual posts manually is easier than driving any post of any length to a standard height marked on the ramming shaft. What if you had 100+ posts? You'd be there all day... thats not easier.
i have used a few different post knockers and that is a well designed and well made job.
Maybe put a rubber matt on that plate which lays on the post? Should reduce noise. Great build!!
and wear on either the plate or worse Gas bottle bottom. Easier replacing a bit of rubber than weld up a cracked gas bottle.
Jees im gonna try get me some of your DIY drive. Another inspirational bit of never before seen genius. Literally every other week your bringing new things I haven't seen before and on the intervening weeks showing your progress. This reminds me of the game fable where you are always levelling up! I'm looking forward to the inevitable moon lander around 2025?
Lovely job Kris!
Great build. Very simple and it beats breaking your back!
Fantastic! Nice. Looks great Kris.
The reason you're getting perosity is because of the scaling they use on the metal. They also brush a very little film of protective oil to wick away moisture. So 3 tips when welding, 1: clean metal with soapy water 2: polish the metal to bare metal using sanding paper, grinder, scotch brite and 3: test your gas/voltage on scrap pieces of metal that are the same thickness.
Yep In the US that is known as "Mill Scale". That Porosity is for sure from not removing the Mill Scale.....At times It can be a Bugger to remove.
If you ever come to the U.S. I’d love to have you as a neighbor. Every farmer in America said, lol.
Kris you are a very intelligant man very good job brother BILL
Well done brother! I think I've watched all of your videos and this is, as you would say "bang on".😀 And almost every time I watch your videos I say to myself "safety glasses are a thing"! Please for the love of all that is precious, holy and or sacred in your life, where your f****** safety glasses! I say this with love and please set a good example for all of the young and old creatures out there.
Kris, love the design and execution of the building of such a fine machine, simplicity is often the best way, and hand built takes it to a whole new level, great work, it has inspired me to build one of my own, I have to ask, how did you work out the size of the mounting frame, and what size has bottle did you use for the weight, what is the length of the steel beam , I have the possibility of some additional hydraulic parts so I might add a hydraulic top link and side tilt adjustment
Just found this today. Binge watched.👍👍👍👍👍
Was thinking, get some polly tunnels for some plum, pear, cherry and apple orchards and i was thinking get a ground drill set up for your tractor too and you could have wells and irrigation everywhere....Also you could fill that drum with dumbbell weights... Drilled washers and your well drill and weights all sorted with a electric metal drill. Later's Kris.
Was also wondering where your straw church was and your hay storage for a horse dude?...x
I for one am glad you had to re-upload because I did not get the notification for the first video it is unfortunate that you had to take the time to post twice though
I'd be proud if I'd made that mate. "Works a treat" 👏
Now that is bloody well done! Bit of great fun engineering right there.
An awesome gadget and very well presented. I love it.
Why was the video taken down and then popped up again a short while later?
Nice bit of work! That will make fencing a lot easier!
This is awesome. Can't help but also see the potential for someone's head or hands to get whacked tho... Seems like it can be operated perfectly safely in most conditions but maybe some kind of guard around the plate or shielding the fall of the weight would make this a bit safer, let's say you have kids around or want to let someone else do some pole whacking who doesn't have your experience. Not to detract from an amazing fabrication job!
You do such great work in so many areas, but please remove the mill scale and rust from your metal before you weld and your weld will be so much better (will lay easier) and be much stronger. Preparation is 90% of welding. Keep up the great work!
it is awesome your work, i can't believe how indepedent you are and creative
Always look forward to your videos wish u did more of them.
Absolutely brilliant,ur a clever guy .well done
Brilliant work kris well done Australia.
kris you’re the fuckin man! shows what you can do with a few bits of metal and some brain power! you force yourself to learn and apply and only through telling people what i have learned from you do i realise just how far you have come in your journey!
truly inspiring! you are of the old ilk my friend! 👏🏻😎
