Its really great the worldwide community the internet has created. Friends coming from all over to help Keith with this project is fantastic. Even living in the UK I feel like I know you all as friends.
it gave me a warm feeling seeing you guys working together This is the American spirit that made your country ...Respect ...From a English Man Living in France !!!!!!!!!
Great job Keith and crew. Can't wait to see the mast go up. Also on a side note... Ginger is slipping on her cat duties... She did not leave her footie prints in the concrete.
Beautiful to see so many family come by to help. Good planning, and smart helpers make for fast work. That went down with hardly a hitch. So looking forward to seeing the crane put together.
I like when guys show up wearing a back brace, most have worked hard and their backs always are sore. Instead of taking it easy, most of these guys just get a back brace and just keep on working hard! Nice job guys!
Wow Keith, the jib project started out well. It was great the amount of help you received on the hardest work portion of the project. The equipment loaned to you was fantastic in making it easier and a better pour. All the folks who were able to come over and help along with those who loaned the equipment deserve a big hand and thank you. Great job everyone, I know Keith really appreciated the help along with all of us who follow along on youtube. Thanks for sharing.
*- To the younger friend with the gray skull cap, Zane; Thank you for bringing your concrete form work experience to help Kieth and the rest of your friends.* *- Good job everyone. It is nice to see men so easily working as a cooperative, supportive unit.*
Excellent! Very well done as you made a quality video and a g ood base for the jib crane. I ignored the people walking in front of the camera because they were to work.
No need to apologize for blocking the camera Keith, we can still see what's going on Hell I'd say we're lucky that we even got any footage at all considering how much needed to be done, I wouldn't have blamed you for not filming all things considered, so thanks! 👍👍
A jib crane is one of the best tools to have in a metal working shop. Congrats, will be so nice when it is installed. My compliments to all those people who gave up there time to help. Speaks volumes about their character. Thanks for sharing.
I'm looking forward to seeing you working with the new crane. I can only imagine what is next, but I'm excited!!!! Congratulations on getting it done in short order. Ga. boy here, I'm proud to have you representing for us!!!!!
The best thing about volunteer help is watching guys that know what they are doing and seeing them work their tails off. I heard you say mix 3.7 yards of concrete by hand and nearly fell out of my chair. I then saw that bobcat front loader mixer and said - brilliant tool to get the job done. Hats off to all the crew that took time out of their lives to help Keith dig, form, and pour the foundation for the jib crane. God bless you all and well done lads. A great video Keith considering how busy you were and most of all.... Thanks for sharing!
Interesting to watch and to see the trouble that you took to do the foundation properly. I couldn't possibly give an actual number of jib crane installations and/or relocations that I have done or supervised, but I bet that it exceeds 100. I employed the method that I was taught, modifying it slightly as my experience increased. Each installation was in the same plant, but done in separate era buildings. I understand that our shop floors were specified as 8" floors, but drilling through the floor countlessly numbers of times, much of our shop floor, in the oldest building, was closer 6-7". We had about 25 jib cranes and relocated many of them several times over 3.5 decades of my employment on the maintenance staff. We/I never installed a proper foundation. Our standard solution was wedge style anchors. After I took up leadership, we upgraded to higher tensile strength hardware, but employed the same method. Our jib hoists were mostly 1T, but we had a few smaller tonnage units. We had many brands of jib hoists. We had the simple column, tube and I beam versions; small base to enormous flange re-enforced base; cantilever rear support to Gorbel formed steel systems. Just after I hired on, we modified a jib hoist with several feet of extra I beam reach and didn't upgrade the column base footprint. I think that we grouted one installation due to a sketchy compromised anchor installed. We possibly grouted another or two for similar reasons. Normally, we shimmed the column base to obtain column plumb and torqued the anchors to the shims. We never experienced any installation failure except for the grossly modified unit described. We very occasionally had to retorque an anchor installation shortly after an installation. Our shop was on the hyper safe end of the safety spectrum, but for culture and experience reasons, we always ignored foundation specifications for jib hoists. My experience validated that jib hoist foundation specifications are vastly over engineered. Our shop was stickler for following specifications except for 3 routine violations that I easily recall... No foundation upgrades for jib hoists, seldom foundation upgrades for very large CNC machines and no additional ground rods commonly specified by CNC manufacturers. I applaud you for the expense and effort that you are taking. Certainly compromising the integrity if your shop floor with the slab cutout increases the wisdom of the enormous foundation effort. Hoist manufacturers consistently increased the column size and base footprint over my employment career, probably due to installers like us! This frustrated our industrial engineers, especially after Lean Manufacturing and Continuous Improvement of the Toyoda management system became our operating norm. These practices forced us to cram machinery and workstations into tighter footprint configurations. The enormous later model jib hoists were despised, because the consumed so much floorspace. The newer larger footprint hoists were frequently being pushed into shop areas with less congestion. This allowed repurposing older hoists into tighter congested shop areas. I envy your jib hoist. They are a dream to use, especially if you have lived with a gantry and chainfalls like you and I have in our home shops. You may find better solutions, but we standardized on Harrington 2 speed electric chain hoists in any area that demanded hook travel speed precise control, like you need when positioning work in a lathe, assembly operations and positiong work between centers in a cylindrical grinder. The 2 speed option gives the slow hook travel for precise positioning, but also allows "rapid" travel speeds for standard lifting. The soft start feature is included as pretty standard on modern hoists that we employed. That is a welcome feature too. Harrington was on the affordable end of the industrial hoists spectrum when I was participating in the buying. They proved dependable and were the requested brand by our users. The time, trouble, expense and permanency of a proper foundation would have been a production interruption No Go for our company. A jib hoist relocation would be part of many workstation relocations. Any workstation that demanded a 1T jib hoist was likely only out of operation for a few hours. Weeks long foundation preparation for a hoist installation would have never been allowed for our around-the-clock production operation. We staffed our maintenance crew for around-the-clock service which facilitated shop relocattions with minimal production interruption. I installed a 14k # 2 post vehicle lift in my home shop. I installed the specified 8" concrete floor and used the manufacturer supplied wedge anchors. This hoist has "tiny" column footprint. I have had trucks on my lift using full rated capacity. I place jack stands to steady those heavy loads, but I have had no anchor issues. You have demonstrated sketchy work in other videos and that commonly brings out the hater comments, but you won't warrant any hater comments on this effort. You went the extra mile!
Hi Keith, I've followed you for some time I have to say you are amazing, I've been a self taught machinist for 40 plus years but I learn form you all the time and I'm often amazed at what you do. It's no wonder there are people willing to come over to your shop t help you continue what your teaching us.
Great job a wonderful group of people to share the work and lend a hand. I was impressed with everyone involved standing in the rain not running for cover. Sharing the discomfort as well. 👍
Great to see the mix on the team from the young studs to the war horses and the super experienced! Looks like everyone was working steady and always helping out. Fantastic.. Now I will have to start shopping for a crane!
Ever since you showed the arrival of that jib crane; I have been looking forward to seeing this installation. It is not like anything else you have done! I know a shop that has a six ton example, and it is worth its weight in gold! Well done gents! TM retired but interested in KR projects.
Agree with the other folk. So nice in theses days that communities come to those in need. Nice one guys. Love from the U.K love Keith and his knowledge and skill god bless guys. 👍🏼👍🏼👍🏼🤜🏻🤜🏻🤜🏻🤜🏻🫶🏼🇬🇧🇺🇸
I love the teaching that Keith does. I _know_ that you do _not_ ever weld rebar. Concrete structures are subject to thermal expansion and contraction due to temperature changes. Tying rebar with wire allows for some movement between the rebar and the concrete without causing stress concentrations or failure points. Welding rebar together would restrict this movement and could lead to cracking or structural damage. Welding can alter the metallurgical properties of the rebar, potentially reducing its resistance to corrosion. Tying with wire preserves the integrity of the rebar material, helping to maintain its durability, ductility, and longevity in concrete structures.
Great to see everyone helping out. One tip if you need to start using a foundation as fast as possible is to ask for a high early mix and to ask for 3 test cylinders to be poured and then tested at 24 hours after the pour, 3 days after the pour, and 1 week after the pour. Most concrete mixes test out higher than the stated design value and the foundation load capacity is based on the design numbers, not the actual numbers. The good thing about concrete is it gets stronger over time. A foundation can be used for the designed load as soon as a cylinder break exceeds the design values. I have seen 3,000 PSI design mixes test out at over 3,000 PSI in a couple of days and to eventually hit over 5,000 PSI on a 30-day break. Most concrete plants use a bit more cement in their mixes than the design calls for as a safety margin so they don't end up having to pay for replacement of an understrength foundation. Just some FYI for any folks who may have a quick need for a foundation.
When you have help that will do the job in the pouring rain you have GOOD help... Wish I had known and I would have came down to help. I am only about 60 miles north. Glad y'all got it done.
NOW! (if you want my trick) Get a paver brick, get a kneeling pad, get a bucket of water, hold the paver brick in your hand like it was a sponge and get down on your hands and knees and swish and wipe the wet paver around like youre trying to wipe spilled ketchup off your kitchen floor! It will "wet sand" all those spill marks and blend the edges in PERFECTLY and help make the transition go away around the square!!! I have done this on pool deck plumbing repairs and other similar concrete repairs with great results.............
Great job guys! Quick comment, having worked in a concrete testing lab, concrete will achieve 75% of its strength in 7 days and pretty near 100 % in 28 days. However, that is under ideal conditions. You have a significant mass of concrete there. It will generate a lot of heat and you have no way of keeping it at ideal curing temperatures, all of which will slow down the curing process. In an exercise of extreme caution, and with a recognition of the loads that will be exerted on this block, you may want to double the curing time frames you were using. Just my thoughts. Love your site!
Very well done Keith and crew. An excellent job that was obviously planned and prepared well. Like most jobs, it's all in the planning and preparation.
Great group of guys, this will be a major game changer! after the surgeries and problems Keith has had in the past few years I'm really glad this is getting put in. I know the gantry works fine, but it's still a pain to drag around the shop and this will save a ton of time and energy. I'm really happy for you Keith!
Keith you can make a bow float from 3" wide aluminum plate. Use a piece of 1"x6" scrap wood, just nailed it. Five minutes on the grinder will smooth the edges and knock the corners. Even 1/4 plywood does the trick too.
Well Keith, Yer doing it right and this is a big/great upgrade for the shop. Lots to pay attention to with on a prep like this. What a great bunch of fellas giving you a hand with this. From my knowledge you have a good case of over achievement happening here and that pleases me to no end. Take care Keith and I will drop in for all your next posts.
21:43 The old 28 Days = 90% strength rule!! :) It's still a good rule, because not everyone knows how to mix concert as well as Keith and the crews here does!! The manufacture is assuming the worst case scenario AND eliminates them from Liability by using this old rule. It takes up to 2 years to go from 90% to 100%, and concrete continues to harden for decades!! Old timers claim it gets to 110% strength in 75 years Fact is 4,000 to 5,000 PSI air entrained concrete poured correctly, has 75% strength in just 7 days, This becomes vital in fast paced construction where every hour counts, before the next higher floor of a building can be erected. Most college educated concrete technologists, call the 28 day 90% rule an old myth .. but for those of us pouring concrete at our home or shop? The 28 Day 90% rule, is a good rule to follow, in my opinion!! Great job Keith, you guys really looked professional and that Jib Crane Blok will be investigated as an ancient artifact, by Archeologists 1000 years from now!! :)
Thanks again Keith for another great video👏👏 wonderful to see you getting all that support. I was wishing I was there in the middle of it all. Not too easy to get there from the south coast of Ireland.
Great job. You guys certainly are NOT navvies, but you got the job done. Pass on MY thanks to the guys and the folks that loaned you the tools and I'm looking forward to the rest of the job. Cheers, Keith
If any of that concrete is high when you set the crane, you can get a diamond wheel that fits a small 4” grinder. They cut pretty aggressively and you can get them from Lowes or Home Depot, they don’t cost very much but they work great and last a long time.
Kieth, a little back saver I've learned.... when you need to dig a hold like that, go in first with a gas auger and bore some holes to depth and loosen it up. It'll make the digging a lot easier. Not much help this time around, but if you ever need to do anything like this again....
That won't be do much considering the cube is four feet thick. It will take that wet ready mix months to cure nevermind the recommended 28 days. That was not the cement to use.
Grunt work is vital, but I won't lie: One thing nice about becoming handicapped (two genetic disorders that have led to four back surgeries and limited mobility at age 63) is that I can, without guilt or shame, say that I've done my lifetime's share of it. Until, of course, those times when I just have to because, well, stuff happens! Great work done here, guys!
Company I worked for years ago took out one jib crane and installed a MUCH bigger one. The slab we had to cut was 4' thick and the hole we cut was about 10' x 10'
Keith, watching you channel since many years and i really like your approach to get things done maybe not the most efficient way rather in real craftmansship - a real differentiator to all those self declared “experts”. Keep going that way! Maybe to give a little bit back - unless you have special “quick curing” concrete (which I think it isn`t, as i came from ready bags), you should wait at least 28 days curing time to have the concrete getting the designated strength to put the required torque on your bolts for the Crane. While it may seem at the top to have fully cured, already a few millimeters further inside it looks totally different - and you have there a big block of concrete! Wetting the top of your pour each day for a week or so will help the block curing even better / more homogeneous, preventing curing cracks.
Running the vibrator for more than an instant causes all the rock to go to the bottom and the water to come to the top. I may be wrong but it seemed to me that the vibrating was excessive. Ellis
Nice to see a crowd show up and work so hard! I'm guessing you will not be able to use the crane to reposition the big machines: you mentioned letting the concrete cure a month...
12:07 VERY GOOD!!! Basically you never weld re-bar!!! The welds are brittle and not very strong!!! There is a welding procedure for specialized rebar ... BUT it HAS to be rebar with a "W" in the part number!!! And the average guy has never seen any of that special re-bar ... Overlap and wire tie is THE correct procedure, Nice one .. everything is really good!
You couldn't be more wrong. - Go buy a copy of AWS D1.1 and check out D12.1 - And you trying to tell us that a TIED joint is stronger then a welded joint. - Where did you learn that-Bob Villa U? -
Its really great the worldwide community the internet has created. Friends coming from all over to help Keith with this project is fantastic. Even living in the UK I feel like I know you all as friends.
Looks like top notch helpers. Kudos to you all for helping Keith.
What a great community of people you have watching, commenting, and showing up to help. Good on them.
Wow it is good to see the community come together to put a project together. Thanks to all the volunteers and to Keith for the video
Very Professionally Carried out !
7 days for Initial Set, 28 days for final set . ! Then Grouting !
Very well thought out Kieth !
Stay safe !
Stu xx
As Keith said, they're actually just following the manufacturer's instructions.
Great job everybody! You are all so awesome to show up for free labor. What an amazing group of guys.
it gave me a warm feeling seeing you guys working together This is the American spirit that made your country ...Respect ...From a English Man Living in France !!!!!!!!!
Great job Keith and crew. Can't wait to see the mast go up. Also on a side note... Ginger is slipping on her cat duties... She did not leave her footie prints in the concrete.
I wonder if that means it did not pass the cat scan?
Beautiful to see so many family come by to help. Good planning, and smart helpers make for fast work. That went down with hardly a hitch.
So looking forward to seeing the crane put together.
I like when guys show up wearing a back brace, most have worked hard and their backs always are sore. Instead of taking it easy, most of these guys just get a back brace and just keep on working hard! Nice job guys!

No problem watching people walk near the camera.

Good friends are gold!
Happy to see you had plenty of help and thank you to all of the gentlemen who came out and helped you.
Nice job Keith. I see you had enough people to help you out, so my presence was not required. Congrats with the result.
A jib crane is one of the best tools to have in a metal working shop. Congrats, will be so nice when it is installed. My compliments to all those people who gave up there time to help. Speaks volumes about their character. Thanks for sharing.

You have demonstrated sketchy work in other videos and that commonly brings out the hater comments, but you won't warrant any hater comments on this effort. You went the extra mile!

It's no wonder there are people willing to come over to your shop t help you continue what your teaching us.
I'm a big fan of the voice-over approach. The results are much more comprehensible and enjoyable. I imagine the work is greater though.
I'm not the least bit surprised you had willing helpers. Those who give of themselves freely often have ready hands to help them when the time comes.
Good morning Keith! Glad it worked out so well. Have a great week.
Great job a wonderful group of people to share the work and lend a hand. I was impressed with everyone involved standing in the rain not running for cover. Sharing the discomfort as well. 👍
Great to see the mix on the team from the young studs to the war horses and the super experienced! Looks like everyone was working steady and always helping out. Fantastic.. Now I will have to start shopping for a crane!
Good men are special friends !!!
Great work everyone.
16:00 and again PERFECT, nice timing getting finished the pour by 5 PM!!!
Your crew is dedicated and talented. They earned their skill sets.
That jib crane will be a real help.
It is great seeing a well laid plan come to fruition.
Great!
Ever since you showed the arrival of that jib crane; I have been looking forward to seeing this installation. It is not like anything else you have done! I know a shop that has a six ton example, and it is worth its weight in gold! Well done gents! TM retired but interested in KR projects.
WOW, all the way from Creedmoor, North Carolina! I used to work in Creedmoor. Great Job Guys!

This comment is factually incorrect in all aspects.
Welding is fine if you follow correct procedures.
Thank god for the young blood to help out us older folk. That Kieth looked like a heck of a worker.
"Got it all cleaned up so we can make our next mess" 😂😂
all your prep work moved this project ahead w/o any major stoppage, thxs for sharing...
Excellent team work guys!
Great to see everyone helping out.

When you have help that will do the job in the pouring rain you have GOOD help... Wish I had known and I would have came down to help. I am only about 60 miles north. Glad y'all got it done.

Very well done Keith and crew. An excellent job that was obviously planned and prepared well. Like most jobs, it's all in the planning and preparation.
Glad you got the help you needed to do it right and keep you safe.
Great group of guys, this will be a major game changer! after the surgeries and problems Keith has had in the past few years I'm really glad this is getting put in. I know the gantry works fine, but it's still a pain to drag around the shop and this will save a ton of time and energy. I'm really happy for you Keith!
Keith you can make a bow float from 3" wide aluminum plate. Use a piece of 1"x6" scrap wood, just nailed it. Five minutes on the grinder will smooth the edges and knock the corners. Even 1/4 plywood does the trick too.
Great job! Only two things I didn't see were your autographing the concrete, and the end of job beer.
Looking forward to seeing the crane!
Well Keith, Yer doing it right and this is a big/great upgrade for the shop. Lots to pay attention to with on a prep like this. What a great bunch of fellas giving you a hand with this. From my knowledge you have a good case of over achievement happening here and that pleases me to no end. Take care Keith and I will drop in for all your next posts.
Great tractor Keith
Wow ! First time seeing how large the room is.
10:54 Nice detail tieing that into the existing slab!! ...11:30 Awesome Rebar cage!! . That jib crane is not going anywhere!!! :) Love t!
2:06 Vevy Pleased you are mixing it yourself!! 100% THE way to go!!! Wish I was there!! :(
The money you save, especially with a small pour, is considerable. Hard work, nice job.
Fantastic get together
Good going guys.
21:43 The old 28 Days = 90% strength rule!! :) It's still a good rule, because not everyone knows how to mix concert as well as Keith and the crews here does!! The manufacture is assuming the worst case scenario AND eliminates them from Liability by using this old rule.
It takes up to 2 years to go from 90% to 100%, and concrete continues to harden for decades!! Old timers claim it gets to 110% strength in 75 years
Fact is 4,000 to 5,000 PSI air entrained concrete poured correctly, has 75% strength in just 7 days, This becomes vital in fast paced construction where every hour counts, before the next higher floor of a building can be erected.
Most college educated concrete technologists, call the 28 day 90% rule an old myth .. but for those of us pouring concrete at our home or shop? The 28 Day 90% rule, is a good rule to follow, in my opinion!!
Great job Keith, you guys really looked professional and that Jib Crane Blok will be investigated as an ancient artifact, by Archeologists 1000 years from now!! :)
Thanks again Keith for another great video👏👏 wonderful to see you getting all that support. I was wishing I was there in the middle of it all. Not too easy to get there from the south coast of Ireland.
Great job. You guys certainly are NOT navvies, but you got the job done. Pass on MY thanks to the guys and the folks that loaned you the tools and I'm looking forward to the rest of the job. Cheers, Keith
Super job Keith and team - well done indeed!
Great work Keith and crew!
Great bunch of guys you have there.👍
Can't beat some great friends with helping hands.👍
Thanks for sharing the process.
LOVE the Archer shirt! He rules!!
What a job! Thanks for sharing.
That crane will make a lot of the work you do much easier. Look forward to seeing it happen.
Wow removal looked so simple and easy.
Thanks, Keith. Fun to watch.
Wow you guys did a great job! Kudos to the fellas for really pitching in.
If any of that concrete is high when you set the crane, you can get a diamond wheel that fits a small 4” grinder. They cut pretty aggressively and you can get them from Lowes or Home Depot, they don’t cost very much but they work great and last a long time.
What a great team effort - very impressive.
Nice job
Great operation! Please keep your mobile phones and radio mikes separate!
Kieth, a little back saver I've learned.... when you need to dig a hold like that, go in first with a gas auger and bore some holes to depth and loosen it up. It'll make the digging a lot easier. Not much help this time around, but if you ever need to do anything like this again....
Great Job! Keep the concrete wet for 13 Days!
That won't be do much considering the cube is four feet thick. It will take that wet ready mix months to cure nevermind the recommended 28 days. That was not the cement to use.
Great example of team work❗ Nice job everyone❗😁
Those are some great friends.
That crane ain,t going nowhere ,good job guys.
Heck, I almost drove down there from Montana to help out. Lordy, that’s a long ways!
Noice! Great work to everyone involved, and many thanks for helping Keith!!!
Grunt work is vital, but I won't lie: One thing nice about becoming handicapped (two genetic disorders that have led to four back surgeries and limited mobility at age 63) is that I can, without guilt or shame, say that I've done my lifetime's share of it. Until, of course, those times when I just have to because, well, stuff happens!
Great work done here, guys!
It looks great. Very nice job.
Great job to the whole team!
Nice u had the help and concrete reaches 1/2 strength in 28 days
Thank you Keith!
Company I worked for years ago took out one jib crane and installed a MUCH bigger one. The slab we had to cut was 4' thick and the hole we cut was about 10' x 10'
Keith, watching you channel since many years and i really like your approach to get things done maybe not the most efficient way rather in real craftmansship - a real differentiator to all those self declared “experts”. Keep going that way!
Maybe to give a little bit back - unless you have special “quick curing” concrete (which I think it isn`t, as i came from ready bags), you should wait at least 28 days curing time to have the concrete getting the designated strength to put the required torque on your bolts for the Crane. While it may seem at the top to have fully cured, already a few millimeters further inside it looks totally different - and you have there a big block of concrete! Wetting the top of your pour each day for a week or so will help the block curing even better / more homogeneous, preventing curing cracks.
Thanks Keith good guys to come and help you . Sod’s Law Keith ,if a camera is recording someone will stand in front of it , end of 😂
Running the vibrator for more than an instant causes all the rock to go to the bottom and the water to come to the top. I may be wrong but it seemed to me that the vibrating was excessive. Ellis
Team work, you got to love it so well done
Nice to see a crowd show up and work so hard! I'm guessing you will not be able to use the crane to reposition the big machines: you mentioned letting the concrete cure a month...
This is what working starter looks like 👍
12:07 VERY GOOD!!! Basically you never weld re-bar!!! The welds are brittle and not very strong!!!
There is a welding procedure for specialized rebar ... BUT it HAS to be rebar with a "W" in the part number!!! And the average guy has never seen any of that special re-bar ...
Overlap and wire tie is THE correct procedure, Nice one .. everything is really good!
You couldn't be more wrong. - Go buy a copy of AWS D1.1 and check out D12.1 - And you trying to tell us that a TIED joint is stronger then a welded joint. - Where did you learn that-Bob Villa U? -
Nice Job Keith. Looks like you had plenty of good help too. Ed C
Sweet skid steer attachment.
Thanks for showing this hope to see the crane installation.
Gotta get some kitty prints in it.
