Making a Metal 4x4 Post Driving Cap for Building MTB Features
HTML-код
- Опубликовано: 6 ноя 2021
- In an effort to make driving 4x4's more efficient, we design a post driving cap to protect the top while we strike it with a sledgehammer. The only problem is that we're pretty bad at fabrication. If we can get this working, it will help us build mountain bike features just a little easier!

Weld a handle on it, that’s an amazing idea. Casually leave it in with the other cups at the ranger station lol
Anyone know if this hack is democrat?
Typical a right guy already knows this done...
@@D_Sendit What? It's just a funny mug, every one nows only libertarians are capable that.
@@D_Sendit imagine how miserable your life is when everything has to boil down to political affiliations. It's quite pathetic.

Seth, im done buying your liberal garb and supporting your channel. Wish you luck and ill stay silent until I don't.
If u don't want the end to split u need a (fencing maul) its a sledge hammer but with a much bigger head to stop spliting
listen to em he's a farmer
The plot thickens!
@@agresilience5708 he's just a dog, chill
but I've never ever seen a dog wrong, so..
It can also be called a post maul. It usually has a cast iron head. You can only hit wood with it. I have a 12 and a 16 pound post maul. It will make a man out of you real quick.
You can buy one of these for $30 that will last forever. I've put in hundreds of posts and mine is still solid.
there's a saying for amateur welders that goes "a grinder and paint makes the welder you aint"
Taint
Amateurs? I think the professionals live that motto. Amateurs will just leave their pigeon dropping welds to rust.
Cut a “ + “ shape out of thick plate then bend into the shape! Then the only welds on the piece will not be on the striking surface.
I’d also weld a nail or two on the inside. That way the cap will stay put on the post while you hammer and ideally transfer the energy into the post better instead of bouncing off
But with the nails the shape would get stuck..? Please elaborate
This was exactly my first thought when they said what they were making. They could even weld a band around the perimeter for strength
His biggest issue is poor welds.
Good luck bending such thick metal without a break.
@@lukeman87545 More like poor engineering, those welds had no chance to hold being thick metal welded to thin metal, no matter the quality of the welding. The sides needed to be as thick as the top like on the second prototype.
Evil Seth be like: Today we're going to be doing the same thing, exactly the same way
Evil Berm Peak Express be like: Blockage Bottom Nonspecific
did i ever tell you, what the definition of insanity is?
I would gladly subscribe to that channel too! 😂
If you make a v2 you could just bend a rectangular piece of metal into a "n" shape and just weld 2 square pieces of metal on the side so the thing you're constantly hitting is a single piece of metal and the welded part is just a decorative cap.
This is what I was going to say. Just bend some real thick steel in an "n" as you say. Might even work to just cut off one side of the 4x4 box section and spread the sides a bit to fit over the post. Then just weld something smaller on the sides to act as strapping to keep it from falling off the post while hammering. Then there shouldn't be any stress from hammering going to any welds.
Was just about to write something similar, my idea was to use to U shaped pieces of metal stacked ontop of eachother so the hitting surface is two layers.
That's exactly what I wanted to write! More over, it could be a П-shaped piece of profile with a single hole and a bolt on its side used for holding the wood not to bounce off after every hit.
bending thick metal makes it a lot weaker. I'd say a good welding spot will be actually stronger than a bent piece of metal.
I mean a post driver is $50 probably and might do the work and withhold a sledge hammer
Steel tube has an OD and ID " Outside diameter and inside diameter" also you need to account for warp/ shrinking after the metal cools down but home depot, sells what you are attempting to make, it's called a fence post driver
Seth. I used to build and use a similar tool just to pop 8in deep, 2.5in round holes in the ground. I used 1/4 wall 2.5 pipe and the top plate was 3/16 thick. That 3/16 plate was destroyed after the first 60 or so holes. I ended up doubling up the top plate and plug welding it in the center and all around the outside. Your concept works great and is a stellar idea. Just needs a little more work. Really, the outside doesn't need to be that heavy. It just needs to be strongly attached to the top plate. The heavier it is, when it does get stuck for some reason, it will be a pain to get off. I think less material on the sides is a good idea, with a heavy top.
I work on a ranch and have tried pretty much every method of driving posts in the ground. What I’ve found works best is getting yourself a pallet fork attachment for that excavator and using one of the fork spikes to poke a hole in the ground. Then take your post and use the bottom of your excavator bucket to push it into the ground. Have probably done this to a few hundred 8 foot half rounds and it works great. Have fun figuring it out!
Just wrap the top part with a steel tie, cheep, and solves the original problem.
I can’t tell if this is genius or over complicated
This is the correct answer.
But he don't want to use his excavator in this place to not damage the roots 🤔
@@thelonewolf3515 Honda makes a portable gas powered post driver. They sell it at Home Depot
The best part of the video is always Oscar cluelessly walking around while Seth is talking to the camera.
Edit: this is not meant to be taking bad about the videos it is just a comment about a cute dog you can chill out.
Ouch lol
That's like the worst part, who cares about ugly dog
@@skinheads what the heck dude???
@@skinheads Who cares about stupid mean commenters on the RUclips. Go spread your anger on the many political videos.
I understood what you meant pyro baby yoda
“I don’t know what I was expecting, I guess I was expecting it to not work.” That is exactly the same attitude I approach my diy projects with. I get concerned when it goes according to my plan.
Farmer favourite in the uk: post rammer...old steel gas bottle with the top cut off and two handles added; works a charm.
Hey Seth, good idea, bit of trouble executing. Simple solution to the fit, just take the 4x4's to the table saw and give them the slightest shave on 2 sides so it fits, as you said, only needs like 1/16th all around to fit ;-)
On the welding thing, you need to grind 45 degree angles so the weld actually has someplace to go once you grind it back and you don't basically grind back off al the weld.
And also he maybe has to turn on shielding gas, the beads look like they've been made without or with not enough shielding gas
or to the belt grinder
@@zsomborteimer2821 I think he was using flux-core wire rather than plain wire with separate gas.
@@zsomborteimer2821 He's using flux core. Very difficult to weld such thick material successfully with it and he did as good a job as could be expected. But as we saw it was quite weak... Things aren't ever supposed to break at the welds. The welds should be stronger than the other bits!
@@benc8386 If you crank it up to 90 amps it can weld pretty thick metal. I was welding 0.8 mm thick tubing on my boat trailer today with no issues whatsoever. I had pretty good penetration, sure its not like stick welding, but Im pretty sure it would pass an x-ray.
Other title could be “Seth unknowingly creates a minecraft red stone torch “
Or...How it's made...in China

This is one of my favorite channels cause seth always shows off the process, not just the final product. That’s why colin furze is so good too
Love that you are learning to weld. I weld structural and am trained to weld pipe. No hate towards your welds. Just a tip. Bevel the sides of the metal to allow better penetration. Move slower with your movement and make sure your amperage is hot enough. Tack each side good and weld one side, let it cool. Weld the opposite side. Let it cool and repeat. Keeps things from warping too badly. I love seeing you weld. It's my passion, and I love when people want to learn. Keep doing more!
There's such thing as a stake driver, that's basically a big metal tube with a weight at the end and two handles. Fully recommended.
We use these regularly, that was going to be my same recommendation. Also a lot less work than swinging that bing sledge over and over.
I came here to say the same thing.
I use these to put up temporary signs, they work like a charm, I second this recommendation as well
I've never seen a square one though
Yup, there has to be a ready made stake cap!
He was so excited with the thicker metal. "NOW WERE COOKING WITH GAS!" Amazing. Best part of the video.
4:17
The energy in this video is amazing! The failing and laughing and trying again… it’s so joyful!
What I reaaaally really love about this channel is that you show all the failures along the way. Makes it all very relatable.
4:35 seth went back to the cavman days
This is how we learn my dude. Every "fail" is a learning experience on what not to do the next time.
I would recommend you to buy a 5mm thick steel sheet and cut a cross ( + ) with sides 4" out of it, also considering the added thickness of the sheet and then bending it into a cube and welding the sides. In this way you can actually control the dimensions of it with respect to the wood size and you can weld small 90° steel angles on all 4 welded edges for extra strength so that the welds won't rip on impact. I hope this may be helpful to you.
Nothing wrong with learning like this Seth! It’s still a salvageable project. Just cut the 4” box along the corners on two opposite sides lengthways leaving you with two enormous angle iron, then space them out wide enough to go over the 4x4 and weld them together again.
The best part is bridging the gap with weld is great practice and you’ll be able to play with the welder on hotter settings. Your other welds only failed because they were cold and got mostly ground off. Don’t be scared of gaps in mig welding, perfect fit up is for tig.
Fantastic, I enjoying seeing the fails, it helps when things go wrong here. oh and you can buy driving caps online, I'm pretty sure they use them to drive 4x4s where you can't dig and pack like at docks.
After a few months of lockdown my first job was doing some labor work on building trails. They had two thick metal cylinders with a thick base welded on. The cylinder had handles on each side for two to four people to grab. With the aid of a scrape block we would lift the tube and slam it down repeatedly to drive posts in
One of my favorite videos. You just learned a few ways not to make a post pounder. Absolutely love the channel for this reason. Stay you and stay honest.
2:55 thats the face Im here for...no but for real I love watching your videos, seeing everything getting build, rebuild, getting used and so on. Youre seriously making my days better. :)
When you had the square and just needed a top cap, if you had used a larger top square you could have welded it correctly in a 45 degree angle ( edit: from BELOW the strike surface, put the top square flat and put the sides on top and then weld them so it has room to bind the pieces ). Would have been even better if you used a thicker top cap as well since that's the part which distributes the load, more mass there helps.
Edit2: for the sides if you don't have thicker plates you could try and add ribs from strips of the same metal. Those ribs will greatly enhance the rigidity and prevent warping and splitting.
Seth, thank you for being the best, you got me into mountain biking, around a year ago, and I love it. Thank you😀😀😀😀😀🤟🤟🤟🤟
Kudos to you for keeping your cool. I would have gotten the biggest sledge handy, stuck your creation on the end of a 4x4 and pounded it into the ground until the whole thing was at least 6 inches underground.
I am Subscribed and seen like 5000 of these videos.. I dont understand why you are not comin out on my feed. Anyway been riding for a year now - not as crazy as the stuff I see you doin - but just wanted to know you and your videos were a part of that decision. Thanks for your work/life choices haha keep it up bud!
I think the best part is how creative Seth is to think of these entertaining videos and the way he explains complicated things very well
Good job Seth. And can you name the digger Special Ed or Shifty Murphy because it shifts the tracks
I can’t even count how many times I’ve messed a project up before completed successfully. Watching this and seeing that even Seth can make a mistake (Little metal box) shows me that it’s normal and OK to mess up. Just have to learn and keep trying again
What are you, 15? Nobody is perfect.
@@dystopiaisutopia lmao True that. I am in my 30s and a complete F-up when it comes to taking on projects. Just saying when you see one of the best fail it’s reassurance. It’s easy for people to get in that mindset where they give up or quit.
I am sure there are some welders that have already told you this, but doing a half lap on the the top cover piece and then welding would be stronger. Going a larger channel size should work but I love the determination. Keep it up Seth loving the journey.
Seth, please wear hearing protection while using a grinder. Also, get some flap discs for grinding with.
that's the umbrellla stand sorted for the ranger station.....loved this. Reckon some may not share the "when it doesn't go to plan" content but everyone is glad you do
Make it out of 1/4” plate out of a single plate draw out your bend, cut halfway through with the angle grinder then bend it the rest of the way in the vice then weld your bends. You can make a template out of paper to lay it out!
Would love to see more of the old wood feature builds Seth
Yes I know, another big-brain comment, but hope this helps. Having multiple pieces joined together, the joints are a guaranteed weak link, I would suggest taking sheet metal (3/16" thickness) and bend it in a C-shape then weld one triangular piece on each side like a corner brace to help it retain its shape. The other suggestion that might be easier is to cut off a 4" section of the square stock and cut off one of the sides so you end up with a C-shape piece, then thake the off-cut and cut it into 2 triangles to use them as corner brace if you want but that square stock is pretty tight so those braces are not totally needed. Great video Seth
Nice to see different things and projects happening. Angle grinder disks are known to explode and while nice to see some safety equipment, the energy in an angle grinder disk is such that fragments can go straight through and we don't want you out of action for too long - guards on angle grinders are there for a reason.
"Ahchsfahahcbababab" absolutely beautiful seth. Couldn't be said better
“Wow we just watched him die” lol
I f i explained this video to someone they would think i am kooky for watching it.
Yet it was a great video.
I don’t know how Seth can make a video about pretty much anything and it still is fun to watch.
But he can, and I am glad.
I build my own sliding Hammer thing when i had to set a bunch of posts. Not unlike that one but with a giant weight with handles riding on a solid axel attached to the cup. Worked just fine
id suggest giving it another go, but this time you just use a metal plate and cut it into a cross, and bend it to be an open cube so it all remains mostly one piece and dont rely solely on welds for strength
You're going to have a really bad time trying to bend steel thick enough to withstand the sledgehammer on top, especially trying to close it into a box like that. The HSS with the plate on top is the best way to go, but I would cut the plate about 1/4" larger than the HSS on all sides so you can do a much stronger and easier fillet weld. Those butt welds we was doing especially with his small wire feed and inexperience were super weak and had little penetration.
Have you ever looked into a “post pounder”. It has handles and we use it to bang in fence posts. Maybe that could be a concept?
Square peg, round hole?
@@benjybluehat they come with both
5:13 as you were walking, I was thinking, "Oh, watch this realization." Classic
You need a spokeshave. Just take the edges off the four corners on the top 12" or so of each post. Then the cap
“Now we’re cooking with gas”. Hardest I’ve laughed from one of ur videos, keep up the good work🤘
This is one of my favorite episodes. I'm dying laughing over here, Seth!
You could cut all the corners of metal and bend each side out slightly so it tapers up to top plate. Weld thick metal to replace the structure lost from cutting it. It might be tight at the top but the bottom would slide on fine. Think of a pyramid with the top cut off but much less of a slope to it.
Must be one of the best videos of the year! :D
love it
You are the best!!!
I envy your ability to simply drive a post into the ground. Kinda wish I lived in a place that wasn't clay soil for the top 3 inches, and then nothing but rocks underneath.
No way I'm moving out of Utah, away from the best mountain biking and skiing. It's the price we pay.
This channel has taught me so so so so much about so much, but when it comes to metal work and welding, I get to sit here all smug hahaha
I've been rather ill recently but this is absolutely the relief I needed! You're a legend man.
(edit: I guarantee you It's 100 times better watching as a fabricator)
Seth, you just need a real welder, and someone that knows how to get proper penetration of the parent metal. Then get 5 squares and weld them up like you did at first, but with an actual structural weld.
Most of us that weld will do something like this for next to nothing.
I love watching beginners try to mig. but i could tig it up to where it never could break again.
And weld an old jack hammer bit to the top.
Hey man you should really have a guard on when you're using the cutoff blade like that, that's how people get seriously seriously injured
OSHA requirement for a reason.
@@dystopiaisutopia I haven't gotten to the most dangerous part of the video when I made that comment

Seth what about a straight line down hill speed run section like just from top to bottom straight line with maby a few jumps just a max speed thing
'how quickly do you want to die'
'yes'
@@mscd9676 hmm how fast can I go down there : dead :
that's what his driveway is for
Straight line downhill is a big no no in trail design. Water will channel into the breaking ruts and quickly erode big ruts into the trail. The sediment washed down hill will cover and kill vegetation.
concept was good,
I'd suggest going with .20 inch thick sheet metal, cut a plus shape, bend the sides to form the cup, weld the sides. After this, get an inch-wide, 17-ish inch long, piece of sheet metal, and bend it around the mouth of the cup, to act as a reinforcement to hold the corner welds together, and in such a way that the ends of this reinforcement plate meet at the middle of one of the cup's sides (don't want that weld to be on top of the cup's corner welds, cause that would then become the first failure point) Weld the reinforcement onto the cup's mouth, weld the ends of the bent reinforcement plate together... should last a lifetime I believe.
Ok Seth, you just have to cut with your grinder, one of the corners, just till the upper welded part, this way you release some of the tension. If not working, cut the oposite corner too and put it on that 4x4 wood and to be sure it won't fly you can fix it with a small screw in a hole through one of the sides.
Of course, this is the solution in case you won't make another larger cap. Hope it is useful and reliable.
my long legs/knees hurt just seeing him kneel anywhere/everywhere like that haha
I already know that this is good
Hi
Seth, just use your zip disc and cut down the 4 corners removing the material all the way to the cap. Then use your vice and a hammer to bend each side out so it will fit over the 4x4. For future an open corner fit will make things stronger then a flush cap. Also, please get some sheet metal to top your wood table when welding lol.
4:17 will forever live in my memory. I love it
I know it won't fit the 4x4s when he cut the steel tube.
Seth forgot the inner dimensions of the square tube shoud be equal or larger than the outer dimensions of the wood. 😁
Seems he did account for it, since a 4"x4" post has true dimensions of 3-1/2"x3-1/2" and his box section is 4"x4" with 1/4" walls. Yes, yes, someone will mention tolerances, but what Seth really forgot to account for is that the box section has rounded corners while the post has sharp corners which interfere. Would work find if he manually chamfers every post before he drives it in.😅
Grinder and paint makes me the welder I ain’t.
That was not a failure that was a well-learned experience... knowledge. You grew in your wisdom.
I think just a thick square with 4 rebars welded to the edges would do you good. Cut the square larger than a 4x4 and weld the rebars lengthwise with a 4x4 in place
Seth, making a "prototype" is always the best way to build something that awesome so don't be so hard on yourself! Trial and Error are the keys to success!
EDIT: Leave it in your rental with a hand file and in time the inside will get widened for you 😂
You should make an rc car trail out in the woods
Yes!!!
Welding tip: It is easier to weld in an 90° Corner instead of the 270° you did on the outside top-plate. While welding inside would interfere with the function of your post driving cap, you could go and make the top plate a couple of cm larger than needed, to create the 90° corner on the outside.
Also bending an open cube instead of welding everything could help :)
Your top weld on the first proto was holding after you doubled up on the welds, it was strong enough to allow you to bend it back without snapping off when the sides split. I would have just doubled up on the sides and tried again. Maybe put a 2nd plate on top so it didn't bend in so easy. -Fellow Project Fumbler
That looks like it would make a pretty good vase to put at the ranger station! You also won't risk someone knocking their teeth out :)
Ticket to claim you were here with in a hour
@bermpeakexpress you could cut the square tubing vertically at the corners like so < > to widen it out enough to fit the post. Then tack it together with strips or even diagonal handles.
If someone asked me to make one of those, I'd go with minimum 1/2 thick plate for the strike surface, 3/4 if I can get my hands on it. An 8 pound sledge is probably generating over 3000lbs of force for a split second, therefore to distribute the load you need thicker material.
Please please put a guard on your grinder, it’s so unsafe without 🥽
A disc could easily break if it’s used wrong. Or the pressure you apply while using the machine is too high⚠️
Shrapnel could leave some serious injuries❤️🩹
Edit: emojis in the hope that this comment will reach Seth faster.
🤓
Also do not use the front of the disc like at 4:28 (especially without a guard). If a kickback happens there is a high change of getting hit by the disc since it is trying to push upwards instead of forwards.
Edit: It also seems like the angle grinder is setup to go in to the wrong direction. The sparks should be flying towards you instead of away from you. That just seems like a accident waiting to happen.
Hey Seth, I remember seeing a guy somewhere on RUclips who drove posts with a running plate compactor hanging from his Mini digger. Maybe that could work for you.
Love these videos, thanks!
Get a sheet of plate steel, thick enough, 8x8". Weld some pieces underneath the middle of one side that will allow you to place it on the end of the post, and keep it in place. The unwelded flat side of the 8x8" plate will be facing up. Use the excavator bucket to drive the posts.
Seth: (About V2) it's kinda hot , doesn't fit
Me: Let it cool down it might just fit
Yeah! Science!
"Dang we just watched him die"

For the love of whoever you pray to, PLEASE PUT ON THE GRINDER GUARD WHILE USING THE CUT OFF WHEEL!!! I'm sure some will say its fine but seriously, an exploding disc is NOT FUN.
One of my fave of your vids
When it comes to welding thick gauge steel, chamfer the edges. Butt welding works best if you’re arc welding at this gauge. If you’re mig welding slow down, and increase your wire feed.
Heavily tack it 5 or 6 times along each edge before doing a continual weld.
The reason it split is because if something called under fill. The weld isn’t actually attached at the top or the bottom, just where the filler wire made contact. Move the wire from the top of the join to the bottom, that way you’re getting conduction and not just a slag pool that blobs and spreads out.
Also even when you E been welding years, it’s still always a good idea to practice a weld on any new material you get. So you can dial the settings in.
For real my dude you need to put the guard back on your angle grinder, I'm genuinely concerned for your safety, at 4:37 if the blade would have broken you could have lost an arm or fingers or hand, and at 5:01 if the blade would have broken you could have got shrapnel in your lungs or heart, play that's a legit potentially deadly mistake my dude in the type of Blade you're using or the type that break all the time, it's not uncommon to the point where if you keep on using those blades consistently there's a good chance is's going to happen to you one day. I never ask for likes but please like this so Seth sees it.
Not to be "that guy" Seth, but please either put the guard back on the grinder or at least use grind+ function on the Vlukan helmet (there is a switch near the "delay time" dial). As you probably know, those cutting disks can explode and turn your face into a meat-pie if you don't have the proper protection. This advice is coming from a NYS DOT certified Stick Welder.
Seth use a piece of 6” sch 40 pipe and weld 1/4” plate on the one end. Cut the plate bigger then the outside diameter of the pipe so you can make a fillet weld. Always bevel the end of the material you are welding you can make multiple passes. The reason the first one broke was you made a butt weld then grinded the weld off to make it look pretty. But you had no weld left to hold it together.
Even though it was a failure, it was still entertaining 👍 Reminds me of Jamie from MythBusters, always make sure what you're building can fit out of the shop door when you're finished!
“NOW WE’RE COOKIN’ WITH GAS!!” Please make this a t-shirt lol. That part cracked me up
4:17
My god its so refreshing watching Seth mess up over and over... im not the only one haha
i like that u are confident to show ur welds to us :D
Cut the angles of the block like 1" from end. This will leave you with sides that are 2" wide and without angles. Cut from the stock a peace with the same length as the block. Now cut it into 4 by the middle of each side. Now you will get new L profiles. Grind the ends a bit in angle towards the outside. Weld them to the outside of the block. Now that radius at the corners will be further away and the block should fit.
Also - a little bit higher current will help a little bit with the strength. The first block was with bad welds because the metal was not melted.
