Fabricating a 3 point linkage weight frame
HTML-код
- Опубликовано: 3 окт 2024
- In this video I fabricate a 3-point linkage weight frame to go on the front of a tractor.
I design the whole thing in Onshape first before I start.
I then cnc plasma cut out the parts, these are cut from 15mm plate. Then main piece is pressed to shape with the press brake.
I cut some 80x80x6 box section to use as the frame: The main beam, the upright and 2 pieces cut at a 45degree angle.
Everything needs a quick sand down and clean up before assembly.
The main beam is slid through the piece of 15mm that was pressed, the 2 extra braces are also put into place and tacked welded, the upright is squared up and tacked and then the two 45degree angle boxes are tacked on.
The bottom link outer plates are tacked on and then the top link brackets.
I decided I’ve got the hole centres between the bottom link and top link too close, so I redesign and plasma out another pair of top link brackets that have a higher hole centre. The old ones are removed and the new ones are tack welded on.
Once I’m happy with how everything is fitted together, I weld everything up.
Before paint, I give the frame and block a degrease and pressure wash off.
The frame is painted with red oxide first and then both are finished in black. Once the paint has dried, I bolt the block to the frame.
Hope you enjoyed the video.
Thanks for watching!

The attention to detail is amazing, turning the box section seams to the back shows tremendous pride in the work, top notch results and I’m loving the snowball logo 👍
I don't think I've ever seen the principle of "Measure Twice, Cut Once" been done so fastidiously.
Nice.
He would make a Swiss watchmaker proud
You would be a great teacher at a Trade School for future fabricators, your design skills and welding kills are second to none. Truly like to watch your fabrication projects. Thank you from Virginia Beach Virginia USA
Reminds me of my ex-Royal Navy Apprenticeship Scheme instructors, commenced as an 11 year old at Bermuda Technical Institute, January 1957. Finest teachers ever !!
Hi Oliver - I think that you should attach your Logo to ALL of your work - this fabrication was to meet a customers need, but your design met that need. excellent.

As craftsmen it’s inevitable we will make a mistake, it’s how we recover from them. That turned out superb, your customer is going to be very happy. 😊
You are a perfectionist Oliver with metal fabrication 👍👍👍
Oliver, every time you use the massive break in your shop, I begin to think of where did it come from and what projects it must have completed for the benefit of customers of the shop it was in. Interesting how the simulation feature shows the stress points of the piece. Thanks for the Sunday morning visit.
Swan Hunter Shipbuilders, Wallsend on Tyne had a huge break.... I was amazed to see flat plating, pre cut + allowances, having corrugations (like a V) being pressed in for rigidity.
WTG Snowwie 👍
A great sunday-video and a very nice holder for the weights!
I especially Like that you take pride in hiding the weld seams of the square tubing, drives me mad when stuff are just put together with the seams pointing in every direction 😊
I love your skills on the CNC!
About fixing your logo: drill two holes through the sprocket, weld it onto the workpiece through these holes and grind the welds flush afterwards.
Good idea!
Wow!
Instead of one shop dog, two chickens are watching your progress.
A truly fowl observation...........
It's difficult to soar with the eagles when you work with a bunch of chickens.
Comparing Chickens to human inspectors is an insult to Chickens.
My safety records are written with handwriting that looks like, 'chicken scratches' so the Chickens do have an advantage.

health and safety
Another great one to enhance our Sunday morning. Thanks. I’m sure I speak for many when I say you don’t need to speed up sections to reduce the time. I’m just as happy watching a one hour video from you as I am a 45 minute one. Putting the box section seams at the back was a nice touch.
Cheers
Mike and Nicky
Another great video, i preferred the sounds of grinding ,weld etc... in the time laps parts over the music.
Amazing work as always Oliver . Got to admit you are giving Kurtis (cee) a run for his money as my favorite fab channel .
CEE still has his franna crane project
Curtis has snakes to deal with and 30+degrees. I’d be waving a little sweaty surrender flag.
Another amazing fabrication, done with forethought, and pride. A work of functional art.
Along with the complete and professional video work, and editing, superb!
For some reason, I loved the leaving the wash area shot, and shop arrival shot.
The chickens in the shop inspecting the fire extinguisher humor was spot on.
Love it how you leave in your little mistakes. Someone I do work for makes out they have never got anything wrong. It gets you down when you are always getting told that you are wrong
Hopefully the sun will shine for at least a week this summer above the Snowball Engineering Metal Magic Workshop.
I love Finland too !
With a bit of shop organisation you could probably store your metal inside, saving some time and consumables. However, I know how difficult it is to find the time to 'organise the shop', when you have a business to run.
I enjoy spending my Sunday morning catching up on your work, even if it 'annoys' the wife a little. She doesn't understand why I work all week doing something similar, and then want to watch you. 😂
I know I don’t have the tidiest of workshops but I definitely don’t have room to be storing 7.5meter lengths of steel inside
Very few places store steel in side place a used to work was pushing like 800+ ton of structural steel out a week the only stuff was kept in side was small back ends at the plasma and some full plates in racks everything else lay outside
The slight error with distance between bottom holes and top link nicely corrected and tbh probably looks better and stronger than the original design.
Top stuff Oliver, I made a weight carrier many years ago and eventually started to bend on the stress points your model highlighted .
Mine didn’t look any where near as professional as yours 😂
I only saw one problem. You are fabricating this way to precisely for farmers. You know they will bend it sooner rather than later. 😀
Olly, none of us would look to see where the seams might be on this. None of us would know what this rack was supposed to be or do in the first place. That’s why we watch you son, you’re a flippen genous!
That’s what my dad used to say, “it’s good enough for farm work” that was well over sixty years ago. Ps, those top link brackets look more pleasing to the eye. No one will ever know about the original discrepancy when oncoming traffic see it going along the road, apart from the viewers that is. Personally i think that frame would enhance any tractor and they would be proud to have it on their front links.
13k visits and only 2k likes it amazes me what is there not to like about your excellent work from desgn to finish, I bet there are not many who could😇 do what you do. Thanks for letting us into your world,
You have, once again, proven to be an ingenious thinker and smart fabricator.
That on shape stress simulator tool is an awesome feature. Thanks for showing that.
Nice strong design on the weight holder. I don't think anyone could break that, so it should be good for decades of service.
Really nice work! Liked and subscribed, looking forward to more. I enjoy seeing what others do to help keep the wheels of the world turning.
We really like the logo. The workshop chickens approve, too. That is another fine piece of engineering/fabrication that you created. We wouldn't expect anything else. Thanks for the excellent video, too.
Beautifully engineered and executed Ollie. The "tip of the day" for me is how you used a straight edge ruler along the side of your cut off saw to extend the virtual cut line to the far side of the box tubing. Keep up the great work and be safe.
You sure made good use of that off-cut, with almost nothing left over after you cut out the pieces for the weight frame.
Top quality job Oliver. Like the way you gave strength to out mounting points by threading the box tube through. The simulation is a great tool to have but so is common sense and you seem to have plenty of that. Keep up the goodwork
I was worried that you had put too much paint on the logo. Good job, and you sorted out that FU with the pin distances!! Ashville, beer and then Snowball Engineering. My day is done!!👍👍
Letting technology work for you. You're utilising it well. Probably my favourite fabrication build. Congratulations on the 40k subscribers.
If you haven't tried the poly or stripper discs for cleaning up oxidised steel, I would recommend, they don't remove material, just the corrosion. Cracking video 👍
I’ll have to give them a try
Well done , turned out really good your customer will be really happy with that , nice video great work
That was a really good job Ollie. Nice to see you expanding your skills with the sheet metal doo dah. Thanks as ever, and good luck with whatever you have planned.
Brilliant fabrication your attention to detail is commendable oliver. Nice little touch adding your logo. One off bespoke pieces are so much harder than a production run.👏🏻👌🏻
Excellent work again. Love the quality of work you turn out mate. I bet you’re work is stronger than many manufacturers stuff 😊
You need a Lock and Lube grease gun tip. It's a game changer. Stays on and no leaks!!!
Love Watching The Stuff You Make,
Just Like To See It In Action.
Great job Oliver. Wouldn't worry too much about the simulation 200% proof loading is well beyond what industry would apply. Its a lot stronger than last week's pole carrier made out of 3mm box section.
Wow another awesome video Oliver, Amazing fabrication.
I learn different things each time I watch you work.
From kiwi land
Got to get it right especially if your client is a Yorkshire farmer they demand the job reet but the price low. Brilliant as usual.
This is a great channel, be proud.
Thank you
@@snowballengineering no, thank you.
Nice job. Maybe a couple of 13mm holes in the gear logo (one north, one south) and then a couple of 'rosebud' welds through the holes could improve the look?
Lovely recovery with the eyehole brackets on the top and it looks right too.
Yes, that’s a good idea
Great job my friend. Not that it's needed for agriculture but the top link is much more elegant than the original plan. Cheers
You and Isaac from ICWeld are on a different level. I’m amazed.
Another great fabrication job! Thanks for sharing Ollie.
late to watch this show . thanks for great show.
Really enjoyed your project. Shop safety officers was a great end to video . Thanks
Another nice build. And equally nice to see the expert chickens' approval as well... Thumbs Up!
Hello Oliver from the USA....excellent work as always. Great content from inception to completion.
Appreciate the time you take to set the camera up Olly, especially as you seem the type who just wants to "crack on" !
Those little angle finders are great, but they never truly switch off. I have one and I slide the battery tray halfway out when I'm finished using it, better than going for it only to find it's died on you.
Throw the battery one in the garbage and buy the Starrett engraved one, I have one that's 30 years old . No batteries to change never needs to be recalibrated.🍻
35:11 You're looking at von Mises stress analysis.
What it's telling you is basically the stress in the material, or the pressure it's being put under (hence it being in Mpa)
If the von Mises stress comes in with a maximum of 35Mpa and you're using steel with a tensile strength of 350Mpa you're at 10% of the maximum load the material will take before it bends and stays bent.
Basically, if your von Mises exceeds your tensile strength it will bend. Keep a significant safety margin in there. You're also accounting for shock loading as it bounces down the road (you can calculate that too).
Note that the colouring may scale to the range of stresses seen, not to what the material you're using can withstand. Bright red might be that 35Mpa, or you might have done horrible things in your design and the maximum is 900Mpa in which case the "good" blue part might still be above the yield point of the material. Just pay attention to the scale basically.
You can also use it to predict how much deflection you will see in a component. There will be the option in there somewhere for that, but I don't use onshape, so I have no clue where you would find it. I normally use simscale for FEA and CFD simulations.
Do the same thing with your log splitter, you'll see what I was talking about on the last video you did on that.
wanted to say the same, hope he reads this. Very well explained.
Thanks for the explanation. Something I definitely need to learn more about/how to use.
@@snowballengineering You've already done it.
Just make sure the material properties are set right and where the fixed points and load points are are correct and hit the go button.
Compare the maximum von Mises with the steel (250Mpa, 350Mpa or whatever it is you're using). If you don't exceed plus some safety margin it you're good to go.
For the dynamic loading, consider this bouncing down the road. You could estimate that when bouncing it might free fall for 200mm from the top of the bounce and then decelerate again over 100mm to the bottom of the bounce as the tyres compress etc.
So, moving under gravity in the free fall the weight will reach about 2m/s after 200mm.
If we then decelerate it again over 100mm we get 20m/s/s of of deceleration.
Our weight is 680kg (1500lb), divide that by 9.8m/s/s to find it's mass, which gives us about 70kg, and then multiplied by our 20 from above and we get an equivalent static weight of 1400kg.
So that 680kg bouncing will apply the same force as 1400kg of static load.
So when you do the analysis, use 1400kg plus a safety factor of 50%, so 2100kg. That will maintain the safety factor even as it bounces.
Well said an excellent explanation..usually in agri machinery design fabricated products we use 2.5 safety margin ,and take the weakest component or area and double that...
The max stress that will be applied to that frame will be "bending stress " and sudden impact,and that's going to come from sudden impacts at speed" such as potholes etc..
That stress analysis you performed is a "static load"deformation .dosnt tell you nothing..as the implement will only be used when it's in motion...tractor moving..
The part you needed to really test was the vertical box section especially where the top link will attach..
⚠️ Warning..that stress analysis simulation is just for knowledge/demonstration purposes only and means didley squat nothing...always only use a verified and calibrated analysis packeges only, if and when an analysis is actually needed...
An "Add ons" analysis packages etc wud not stand up in court if there was a product claim etc...especially if you weren't even properly trained and certified by the software company to use it..
Very neat, smart and strong!! With the plasma and the folder you cam mek owt!
Phil
I think your badge is very awesome and distinct, but I believe you should set it off by painting it a different color maybe just just having it bolted on or somehow fastened on after you assemble the project I think it would really set your products apart
Maybe stainless steel. That logo will never rust.
Fantastic attention to detail and your welds look perfect. Oliver you did a fantastic job. Enjoy your projects and always looking for more.
Awesome job AND cool LOGO! Thx for showing!
Fantastic quality work as usual. It's great you're learning the new software packages will stand you in good stead for sure! 👍👍👍
Brilliant work again Olly . Can't wait for the coasters to start appearing 😀
Top shelf work !
FYI Suggestion: allowing your tape measure to snap back without using your finger to brake it from full impact will eventually lose its accuracy. I NOTICED YOUR METICULOUSLY ACCURATE !
Awesome job as always just goes to show we all learn something new nice to see that stress test without the stress perfect..
Ollie, you are one heck of a fabricator. Direct, to the point and no nonsense! You are Gold. Always enjoy, thanks.
Welding in the new coat...and so it starts.😁 Another enjoyable Sunday. Thanks
I’ve only done a few tacks in it. My welding jacket is the same colour.
Hi Oliver😊another great product leaving your workshop, good design, and plenty strong enough for what the customer needs. Attention to detail is second to none, and swopping the top hitch before you went too far was a good catch, all in all nicely done mate. Thanks for another interesting video, stay safe, best wishe's to you and your's, Stuart UK.
Enjoyable bedtime viewing once again! Spot on olly 😊
Really nice work young man. Enjoy watching.
I would be happy with that coming out good looks real good🤙
Fantastic fabrication and the simulation is great for stress and fatigue points for consideration.
Great work. Love the logo.
Good job, really well done. I see the new coat has begun to look lived in, lol. Your bend radius on the 15mm plate looked really tight, as a rule of thumb we were taught that the bend radius should be 1.5 - 2.0 times the thickness of the plate. The 90° bends should have a radius of around 22.5mm to 30mm. Being too tight could lead to cracking. The Snowball Engineering logo looked good 👍
Just using the tooling I have.
A great bit of kit to hang the weights on great work as usual
Very good job! Young lad! Keep them coming! 👌👍
Excellent work. That fab turned out really awesome. Spot on, Twice.
Amazing content per usual! I look forward to your videos each week and always wish I could be your shadow for a week, the amount of tips and tricks I'd learn would be priceless. Keep up the great work man!
Great job as usual Oliver
Have a great weekend mate 👍
New subscriber 👍 think I've got a few videos to catch up on 😂
Welcome aboard!
Nice job Oliver, you've reminded me that I really need to get my head around Onshape, that simulation feature looks a lot better than my current guesstimate and fingers crossed method!
Thoroughly enjoy following you on your channel.
Very nice video Ollie and fantastic job on the project. I'm sure the customer was quite pleased with the results. I really enjoyed the inspection at the end lol I have a number of those same inspectors myself 😂😂😂
Another quality job Olly thanks for sharing.
Thank you for sharing, always a pleasure watch your project 👍👍👍👍
Such awesome work, Oliver.
Thanks for sharing 👍🏻
Excellent episode, as usual.
nice workmanship there over engendered for sure finishing touch was definitely putting your logo on it for sure you must do this to more of your work as it's a good form of advertising for you as others have say your steel stock needs to come in out of the weather will save you some time in descaling it and the fork lift could do with a wash Cheers
Disappointed,Ollie thought you would leave it snowball red, lol. Great job. I love the program where you can stress test a job. Nice bit of editing there with the welding.
Great video:
Good to see you properly geared up,
Can you ever have enough welding clamps?
And the guy who figures out how to integrate a woolly hat into a welding helmet will make a fortune, transition can be well nippy.
an elegant solution to an error, no one other than the You Tube community would know!
Well done mate, love watching your projects and learning journey! Hope those inspectors weren't too harsh 😅
Bet the person you made its for is going to be well chuffed, brilliant piece of fabrication and welding. Paint job wasn't too bad either. 👍
I wish you could make 5 of them videos each week 😂😂
Great job, love watching your channel 👍👍👍
Thanks young man, the chicken/inspectors talk was well played😂😂
Great work Oliver. Such attention to detail is good to see. Might I suggest you get some name plates made up with your company details and date of manufacture on them for other potential customers to see?
I do have some but they were a little bit big to put on this job neatly.
Ridiculous this fabricating genius has only 40K subs. Come on people, show him some love!
Your comment to quality is inspiring
Ollie, Baz ,Kurtis and Isaac as the four Weldketeers.
Brilliant engineering skills once again pal 👌
I hope you are show casing your work at your local county fair. They used to have 'Ag Days', where all things agricultural were on display. Should be a big hit!
I don’t really make anything in particular to have a stand at a show.

Beware of those two chickens! I watched the movie "Venom-there will be Carnage" yesterday and them were def. living in the Heros apartment!😬🐓🐓😂
Looks good !
Management teams look the same in every country.
Nice job, looks good with your logo on it!
Nice job, love the welded on logo. Thanks for the video!
