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!
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
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 👍
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. @@mauricekeithjohnson2598
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. 😊
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.
@@fredflintstone8048...if you say so...
health and safety
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 😊
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 👍
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.
Ollie, you are one heck of a fabricator. Direct, to the point and no nonsense! You are Gold. Always enjoy, thanks.
You are a perfectionist Oliver with metal fabrication 👍👍👍
Another great video, i preferred the sounds of grinding ,weld etc... in the time laps parts over the music.
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
This is a great channel, be proud.
Thank you
@@snowballengineering no, thank you.
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!
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,
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..
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.
Hopefully the sun will shine for at least a week this summer above the Snowball Engineering Metal Magic Workshop. I love Finland too !
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 😂
Nice strong design on the weight holder. I don't think anyone could break that, so it should be good for decades of service.
You have, once again, proven to be an ingenious thinker and smart fabricator.
Thoroughly enjoy following you on your channel.
You need a Lock and Lube grease gun tip. It's a game changer. Stays on and no leaks!!!
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.
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
You sure made good use of that off-cut, with almost nothing left over after you cut out the pieces for the weight frame.
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
Brilliant video as always Ollie , thank you 👍
Such awesome work, Oliver. Thanks for sharing 👍🏻
That on shape stress simulator tool is an awesome feature. Thanks for showing that.
Nice job, love the welded on logo. Thanks for the video!
Excellent episode, as usual.
Excellent job Oliver. Keep it up!
Another great fabrication job! Thanks for sharing Ollie.
Another quality job Olly thanks for sharing.
Brilliant work again Olly . Can't wait for the coasters to start appearing 😀
Another excellent piece of work !
A great bit of kit to hang the weights on great work as usual
Great job as usual Oliver Have a great weekend mate 👍
Enjoyable bedtime viewing once again! Spot on olly 😊
Great work. Love the logo.
nice project and well done. cheers ben.
Very nicely done and thanks for the video!
Very good job! Young lad! Keep them coming! 👌👍
Another nice build. And equally nice to see the expert chickens' approval as well... Thumbs Up!
Excellent work. That fab turned out really awesome. Spot on, Twice.
Fantastic attention to detail and your welds look perfect. Oliver you did a fantastic job. Enjoy your projects and always looking for more.
Entertaining as usual, thanks Mr Snowball!
Very impressive fella, great skills you have
Thank you for sharing, always a pleasure watch your project 👍👍👍👍
Really nice work young man. Enjoy watching.
Brilliant engineering skills once again pal 👌
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.
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!
What a great service to put the logo!
Very neat, smart and strong!! With the plasma and the folder you cam mek owt! Phil
Fantastic quality work as usual. It's great you're learning the new software packages will stand you in good stead for sure! 👍👍👍
Fantastic fabrication and the simulation is great for stress and fatigue points for consideration.
Your comment to quality is inspiring
Love Watching The Stuff You Make, Just Like To See It In Action.
Awesome job as always just goes to show we all learn something new nice to see that stress test without the stress perfect..
Fabulise design and fab job some power in your brake press💪
Letting technology work for you. You're utilising it well. Probably my favourite fabrication build. Congratulations on the 40k subscribers.
That is one awesome piece of engineering.
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
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
Hello Oliver from the USA....excellent work as always. Great content from inception to completion.
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!
Really enjoyed your project. Shop safety officers was a great end to video . Thanks
Well done mate, love watching your projects and learning journey! Hope those inspectors weren't too harsh 😅
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.
Extremely interesting as usual keep up the good 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.
Wow another awesome video Oliver, Amazing fabrication. I learn different things each time I watch you work. From kiwi land
Great job. congratulations!
Looks good ! Management teams look the same in every country.
Nice work that young man!
Good work Oliver, good video as usual.
Nice job, looks good with your logo on it!
Great job, as always, mate.
Excellent work again. Love the quality of work you turn out mate. I bet you’re work is stronger than many manufacturers stuff 😊
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.
Hey olly you normally bamboozle me with your science! So thank god you have savvy to sort it out mate amazing creations you make come to life 💯🫵🏻🇬🇧
Fantastic work can’t wait for another
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.👏🏻👌🏻
Another great video! God bless you mate
I would be happy with that coming out good looks real good🤙
Lovely old job 👏👏👏
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 😂😂😂
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 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!!👍👍
You got skills man nice work
Thanks Olly another good job well done
Another brilliant video - Thanks!
What ever the trade something comes along once in awhile you have to change ( can't think of everything ) but you'll say to yourself "ah ha ! I'll remember that for next time " but something else will come along and put a spanner in the works !😁😁😁😁😁 Nice bit of fabrication , Wear gloves ! 👍👍👍👍👍👍👍👍👍
Very impressive looks a good job thanks.
Amazing job, you are the best.
1st class job as usual.
Looking forward to this masterpiece
