Is it just me or did the mast deflect when the guy hung off it? I watched it a couple times and that’s what it looks like. If so, I would try and rig some kind of support to the top of the mast just under the bushings.
1966cambo no no that shit looked like it was going to go over 😂😂😂 he should of had the top go straight to the ceiling first time using it bet it starts to bend
Cantilever beams will always deflect SOME under a load... Just because you can see it doesn't mean it's bad. I'm sure the pipe is still FAR from plastic deformation under the loads he's rated it for.
@@KevinDay Its not so much an issue with plastic deformation as deflection, when the jib sags and your beam trolley runs to the end of it deflecting even more. Or in this case, right off the end, as it looks like there isn't a stop for the trolley.
that jib crane is stronger than really needed for 500 lbs, it is a nice job, at final adjustment, the most important is to align the pivot axis very plumb to avoid rotational non desired movement.
Nice job, but you need to do a load test on this jib. It should carry at least 3x its rating at full extension without sag or buckle or collapse. You don't hoist all the way up. Just an inch off the floor will prove it.
This jib was built by someone with no engineering background in jib crane design requirements or safety. Its totally obvious. At the very least, he should have had it inspected by a certified crane inspector or company. It would never pass. Your'e the one with the bullshit opinion.
@@adamkalman6011 for lift a minimum of 4/1 safety for the structure must be applied per CMAA and ANSI if your really want to get technical. There is a good chance this guy gets sued when this kills someone and they say I learned to build it from this guy on the internet.
@@mrdavidurquhart Lateral torsional buckling of the cantilever boom is a hugh problem that is not directly related to the bending stresses in the steel. Also, it seemed to deflect too much at the top when one of the helpers swung on it. A failure of this structure would probably take place very suddenly, without warning, and that is the most dangerous kind of failure.
I had plans to make a light duty crane in the back of my cube van but if that one is limited to 500 lbs then my design would have been useless. Thanks for sharing.
Well, I find that I always need just one more pass of the spray, and we know what happens then. I just painted the headstock of one of my lathes. Where’s the sandpaper again?
Wouldn't hurt to go over it with a wire wheel. Your welds won't be any good with all that contamination. Just some constructive criticism. And did u get it load tested to put SWL on it?
Thank you so much for a good quality video. I will state, you're plumb lucky, though, that even with machinist style safety glasses, without wearing a full face shield, while using an angle grinder, you havent got multi-scars on your face and neck from the hot metal you're removing. I've worked metal all my life and have seen folks that started out with the same safety ideas..."safety glasses are enough...I don't like all that junk hanging in front of me...or...it gets in my way...until someone has to go to the emergency room when they ground toward a gusset and it spit back on them and they were burnt their face all up. You guy are great!...and LUCKY !!!
To prevent warping when you welded that base up you should have welded IT to the table. 6or 8 good tacks around the perimeter. Then do all your welding, let cool, and cut free. No warpage.
UHMW - Ultra High Molecular Weight - similar to Teflon - it's a high density plastic that works very well as a bearing/bushing in moderate load applications. (Now that you know what it's called - ) you can google it - it's not terribly expensive, and is pretty cool stuff.
It's actually in the polyethylene family instead of the "teflon" family. Cheaper than delrin but good strength, machine-ability and low friction. good stuff for wear parts that need to be tougher than teflon.
Why not use ball Bearing instead of plastic. I know plastic is cheaper but will not last a lifetime. If I had enough over head room I put one in my garage. Still trying to figure that one out. By the way nice work
I always have one of the speed squares on hand that I have cut a small diagonal off the right angle for straddling weld beads. Very handy. Nice project. Take care. Doug
With a few Coupling Nuts, some 1/2" lengths of threaded rod....You could devise a linear guide that will track across any angles.... Even Circles of any diameter. X-Y table with some Z height options... all ya need is.... CNC technology .... CAD/CAM knowledge.... EpoxyMineral Machine bases... Trunnion / Rotary Table / Indexing Plates...
Did you carry out deflection tests to back up your safe working load calculations? Should have, otherwise your insurance could be nullified. Anyway that’s how it works on this side of the pond. Regards.
That big crane only lifts 500 lbs? The one I got from the big box store holds a lot more and is half the size. I agree with another viewer that the money spent on materials would out way the quality plus the labor and time away from other projects. I'm just saying...
I liked that big circular saw from the furture, cut that beam so easy...why not cut that sheet with it,ng? Like these videos but have no welding stuff,no lathe nothing😞 i like to watch who knows maye 1 day
You'd have been better served to have run your mast 3 foot higher and then run a 1 inch diameter tensioning rod with shackles on both ends to act a truss for your beam .
Great job, given me ideas thanks...novices put on a welding jacket. You would be amazed at how quickly welding can give u radiation burns from the light; it's not just the sparks!
wow nice shop and killer jib crane. i was going to serf the couch tomorrow but getting a plan and parts for my jib project has been to long in the waiting. thanks for the motivation and i hope i don't kill myself. ill let the neighbor kid check mine out also, hehee ;)
@Patrick Elliott noise? Time to get your hearing checked, and or something is wrong with u our speakers or listening device because clearly something is wrong. Glad music and art of this video are included,adding to the experience. The only noise I hear are your posts.
Get you a pneumatic floppy disc grinder a some 3M green corps disc and you'll be shocked at there life span and for some sticky or just bad about clogging the disc in the rental department at home depot they have red floppy disc Snap on sells the grinders and Mac etc.
Thanks Leo, you still need to stop by the shop when you are down this way, give Kolton a call when you are in the area and if he isn't here he can pass along my number.
As for the Ads, I have nothing against them, but they should be at the end as most others are. Otherwise, that was great. If I only had room for one here, at home.
Everything Walter makes that I've used is pretty damn good. They are like 3M. You pay, but you get results. (That's why I buy all I can at auctions or I'd have no fun money left!)
there are thousands of people around the world welding with only a t shirt. I can only chock comments like this up to ignorance in the understanding of how many people there are in the world and that those people's lives are not much different from ours. When someone posts a comment saying "Am I the only one who " " ?" It is either fishing for likes or just plain ignorance. Anyone with sense knows that there are a lot of other people doing the exact same thing at the exact same time across the world,
Don't feel bad my 3M flap discs don't last or work near as well as a regular grinding wheel and or sanding discs. Expensive and not very productive. Good project. Take care. Doug
I find that the better (more $$$) disks work great and last a long time on bare metal, removing scale seems to eat them up, or to be more accurate glaze them over so they stop cutting.
I buy my flap disks on amazon Look up benchmark abrasives They have several different grits Last time i got them it was $20 for a 10 pack and they are the blue zirconium ones as opposed to $6 for 1 at yer local store. They seem to last just as good as name brand. As long as yer not using on paint or scale clogging them up

I noticed on the jib crane part 2 you did not grind the rust off the I-beam. Just curious. Not criticizing.
Great project design. Good prep work and good welding as well. I appreciate the common sense approach and attention to detail. Two thumbs up.....
How are you filling the holes, does that torch dump materials in to that i dont see the rods
@Jim Alley no..i don't know anything about that stuff..i have seen the oxy acetylene like a car garage, but i never worked with that.. I did plumbing
It's MiG welding the wire is feed through the gun

hey bro. I'm newly here in your channel. wanna ask a question, is that a plasma cutter you are using to cut thick steel?
Yes, it's just a cheap one from Eastwood, but it does the job. Thanks for watching and commenting

Nice job, but you need to do a load test on this jib. It should carry at least 3x its rating at full extension without sag or buckle or collapse. You don't hoist all the way up. Just an inch off the floor will prove it.
bullshit it does not need to lift 3X its rating maybe 15% more just for safety margin and added a little UNCOMMON SENSE and you are good to go
This jib was built by someone with no engineering background in jib crane design requirements or safety. Its totally obvious. At the very least, he should have had it inspected by a certified crane inspector or company. It would never pass. Your'e the one with the bullshit opinion.

Yes, I was disappointed with that low lift weight; I only need to lift 200Kg but I dotn want to make that monster.
I chuckled when I could see the runs in the final photo of the video. Nice work I really like your design.
Yeah all that careful work and I make a bone head move like that, I can laugh about it now at least.
Well, I find that I always need just one more pass of the spray, and we know what happens then. I just painted the headstock of one of my lathes. Where’s the sandpaper again?
Are you using mig or flux core ? Just wondering
No, solid .035 and c25 gas
Wouldn't hurt to go over it with a wire wheel. Your welds won't be any good with all that contamination. Just some constructive criticism. And did u get it load tested to put SWL on it?
Hows it working out?
The mast seriously deflects with a 160lb man swinging from it!!! No way in hell I would put "500lbs" on that death trap.
Pussy

What was the name of the bushing material. I heard you say UVHW?
UHMW - Ultra High Molecular Weight - similar to Teflon - it's a high density plastic that works very well as a bearing/bushing in moderate load applications. (Now that you know what it's called - ) you can google it - it's not terribly expensive, and is pretty cool stuff.
It's actually in the polyethylene family instead of the "teflon" family. Cheaper than delrin but good strength, machine-ability and low friction. good stuff for wear parts that need to be tougher than teflon.
How did you anchor it to the floor? Did you pour a concrete base for it with bolts coming out of the concrete? Looks great!!
This was discussed at the start of part 1.
THANK YOU FOR GREAT DETAIL ON HOW BUILD YOUR CANE

Hi Dear & many thanks to Nice Work So Would ask you, Which kind of Welding you Ues...
Why not use ball Bearing instead of plastic. I know plastic is cheaper but will not last a lifetime. If I had enough over head room I put one in my garage. Still trying to figure that one out. By the way nice work

NICE JOB LOOKS GOOD
Useful information
Good music, great narration, excellent project!
Like the way you just plucked a figure out of thin air for the SWL lol
Awesome job
Sir jib crane length wise capacity calculation Stating to end
The gussets would be better structurally if they had been over the support plates to better transfer the load. Bet it support 2000 lbs.
Hey Great Job! Build me one too. Do you sell the plans? I would love to have a smaller one for my truck. Thanks for Sharing.

Mild steel always draws ( moves or warps ) to the heat. If you tack it on your left hand side it will draw to your left

Bueno y realmente levanta 500 lbs?. No lo enseñas
how come you didn't play the "music" on the t shirt commercial ?
Lol vertical down isn’t a no no depends on the wps military welding they ask for vertical down alot
Hi can you help me make a 1 tonne jib cane
Whoa that is great. I need to make myself one of those. Gotta buy some steel and weld them up with the powerarc. That crane sure would come in handy
Tell me all calculation
Thanks for flashing us with the grinding & welding sparks that is useless because we can’t see what your doing!

You have to touch up after plasma cutting just give you better welding seem with arc or co2 welding.

You'd have been better served to have run your mast 3 foot higher and then run a 1 inch diameter tensioning rod with shackles on both ends to act a truss for your beam .
