Keith, OMG! The box that large Starrett calipers are in has CV-6 written on it! That's the famous Lexington class USS Enterprise from WWII! 😮🥰
or Caliper Vernier set number 9...
6 not 9.
CV-6 was a Yorktown class.
@@danielbowman4395 couldn't be, CV-9 was the USS Essex...;^)
A trip to see 'Tally Ho' to inspect the installation of the windlass would be a great adventure.
Leo should sail to Georgia!!
@@realmaxpower Would be a homecoming for the frame timbers as well. :)
I would like to see that
I know I shouldn't be surprised, but I never fail to be impressed by the ingenuity and sophistication of the people who designed machinery long before computers.
Not long ago mathematicians were called Computers, lol.
You and Windy Hill sure put a smile on Leo’s face.
Famous last words... 'I doubt I'll ever lift a ton.' 😂😂😂 Every lifting device I have ever used has ended up used to its maximum capacity at some point. Some, even beyond their rated capacity.
The monarch is just gorgeous
CV-6! From The Grey Ghost herself! The history of that large vernier must be incredible.
Road tripping across the country is fabulous! Only problem is never enough time in the day for all the great places to visit. Have a great time. Safe travels.
Hope you’re having an uneventful but fun road trip. Thanks for taking time to edit you do a great job.
Hey Keith ! Even though the Tally Ho project is done and gone, I remain a fan and subscriber of your channel. Your talent, skills and craftsmanship are amazing to watch.
OMG!
@@garybrenner6236 omg ...what?
Hey Keith the paint job on that jib crane came out looking really nice. So glad to see your shop put back together. When you get back from your great adventure with Clarke at WHF please consider doing a virtual tour of your shop. It sure looks beautiful. Thanks for sharing!
Never saw a pie tape... VERY, very cool how they do that.
Re vernier callipers … doesn’t require batteries... A quick story.
On my old ship I carried a ‘lead line’. Actually a fibre glass, wind up, tape-measure with a lead bulb attached to the end with a length of rope. The rope’s length being the ‘freeboard’ from water surface to handrail. Thus I measure depth of water directly off the tape at the ship’s rail.
All that explanation to say this;
My crew used to jibe me about such an arcane piece of equipment.
My reply, “Works in all weathers, works anywhere around the vessel and DOESN’T REQUIRE BATTERIES “!
👍 Great work Keith and keep the analog world alive. 👍
I've never heard of a Pi Tape! HOW COOL!
Keith, watching your presentations is like doing a university course on machine work. Absolutely excellent! Oakville Ontario Canada
You must be kidding!
Those are some of the coolest analog measuring tools I've seen in a long time. Pretty neat acquisitions, thanks for sharing, Keith.
Now that Keith's great work on the Tally Ho project is done with, we can easily see the need for a fresh clean apron--it looks good!
Pie tape you learn something new every day 😊 thanks Keith
Keith, when you’ve got a lot of others in your workshop, you are going to concentrate on making sure they don’t hurt themselves, and get stuff done to you standards. Lack of video, we’ll live with it.
His standards?
1:22 On the end of the beam, attach a length of cord that reaches just above your head in hand reach so make it easy to pull the beam when the chain's distant. Put something like a golf ball on the end of the cord (a poked hole just large enough to hold a knot in would be easy with a Christmas tree bit).
a "christmas tree bit" ? you mean a "stepdrill" why make a longer more complicated name for something with a pretty short name which describes it perfectly to begin with?
Keith,
When you get to upgrade your hoist to electric, please consider a two speed or variable speed hoist or a variable hoist speed hoist. You are used to a chain fall. A chain fall has one major feature that is not available on most electric hoists, and that is hook travel speed control. I did some Internet sleuthing and found that there are many hook speed options. Our shop employed two common speeds, that were 8 FPM and 16 FPM if I remember correctly. 8 FPM is annoyingly slow for general hoisting and 16 FPM is way too fast for precision placement like you will be doing on your lathe. Two speed is a great alternative. Look for a two speed option on the control switch, slow speed on the push button, but high speed by pushing harder (two position push button). There are multiple hook speed options available, so shop carefully. Our shop eventually settled in a favorite hoist manufacturer, Harrington, 2 speed with incorporated soft start. These were available in single and three phase options. In your hobby shop a lower cost option wouldn't frighten me.
As you know, a chain fall has two major disadvantages, they fatigue the operator and the operator chain is annoyingly always in the way. It gets tangled up in the work being lifted and it can easily marr precision surfaces like paint and lathe ways. A chain bag eliminates the free excess hoist chain from interfering with your work.
Lifting work between centers or aligning a chuck to the spindle requires fine control. The slow hook travel speed is then ideal. The cost differential to get the fine control is extremely operational valuable. Damage to the lathe spindle nose, chipped centers or damaged workpiece cost, justifies any hoist upgrade cost.
I currently work with a 3T gantry and chain falls in my hobby shop. The 3T chain fall is arm wearyingly slow for light load lifting, so I also installed a 1T for general use. The hoists are wonderful to have, but the operator chain is constantly in the way. My 1T is an endless chain antique. I treasure it, because it was my grandfather's, but it is annoying to use. The endless chain cannot be pulled out of the way like modern chain fall operator chain can be.
You have invested way more than was probably necessary installing your jib hoist. I applaud you! Your jib hoist cost justifies installing a more expensive hoist that gives you the functionality you need over your lathe.
A properly installed jib hoist is a dream to use, the hook self centers over the load and moves in infinite placement with inate ease. I want one too!
When upgrading to electric hoist, bring the power to the center of the column from the ceiling via portable cord drop. 8' boom isn't long, but you might consider installing a cord management system to travel with the trolley. Many are readily commercially available, but there are cheap shop built options too.
Once you cross Texas you are almost there.
Bar z sounds like the place to be but a bit of a trek from Doncaster, South Yorkshire. Love the videos.
There is not one square inch in the "Peoples Republic of California" that is the place to be!
Your workshop looks great and very professional. 😊
Have you Carpet Wrapped the lower part of the Crane for Ginger?
That would probably the most use that crane will get!
So glad someone saved all that literature and pictures.. CANT STAND companies that don't do this. Several companies I've contacted literally have NOTHING about what they used to sell 50 years ago. Talked to engineers and executives, not just the front line customer service people. Unbelievable. That's a lot of work! Impressive you got all that done so quickly.
Some nice measuring instruments there Keith , thanks for the video 🥰
Thank you for another Great video. cheers
Thanks for sharing Keith
Good stuff!
Road trips are the best.
My wife planned a trip to Utah the date of the Bash so I'll miss you and Clark.
The box containing the Starrett 50" vernier calipers caught my eye. Written on the box is CV-6 which is the designation for the Yorktown class aircraft carrier USS Enterprise. She was decommissioned in 1947 and scrapped in 1958. I wonder of those calipers were used in the metrology lab on that carrier.
Thanks for teaching us about vernier scales!
Good to see a review of the Jib Crane and adding an Electric Hoist would be the cherry on top. 👍
Thank you Keith!
2:37 - Fell and injured a rotator cuff a while back; couldn't change chucks for 3 months. In not too many birthdays, you'll be pleased you have that.
12:18 - Used to be "The Confederate Airforce", but some donors must have objected.
24:29 - 3.14159 - what tolerance are the tapes supposed to deliver?
27:50 - Done CA to ATL, GA once, CA to OH two or three times, back when some car repair was not uncommon. Fun!
Always interesting the provenance of some of these items that turn up in someone’s possession. The eroded end of the calibres may well have had some ID on it. There must have been some odd looking kit bags carried off these ships at times. Not the usual tooling for the home shop.
16:26 i still use these (vernier) for 3D printing. My brain's wired right, it works fast for me, and it gives me a moment to think as well. Whenever you do something, it's worth taking a moment to think about the measurements you're taking. I see soooo many people of my age and younger that either digitally number, scan or whatever in a blink of an eye, they go to work in the computer aaand... predictably, they're back, because there's something wrong, not quite meshing. Besides, these are trusty and fool proof. They will work right from day one to day last. So long you take care of them and keep them neat, they will faithfully serve you a life time.
I used vernier calipers for years until my eyes got old and I had to switch to digital. Still prefer the analog one.
Same here. There's a podcast that a semi-famous bandsaw user and some of his fellow makers produce that had a recent segment of an episode talking about calipers and how some these days have Bluetooth and USB connections allowing for direct input to CAD, which honestly sounds neat and useful, but they were also lamenting about how every time they tended to pick up their calipers the batteries were dead, and what hacks and tips they had for preserving the batteries when they weren't in use. Digital certainly have their uses, but often times plain old simple vernier is all one needs.
be safe as you travel
If you ever have to machine the drivers on that Vulcan steam locomotive, you will need this pi tapes.! It is critical that all the driving wheels be exactly the same diameter and the only way to reliably measure them is with a pi tape!
What an awesome feeling of relief to get your shop back in working order. Congratulations on the jib crane installation.
It was fun watching Leo taking apart the capstan with help from watching your videos.
Hope to see yall there.
The "extra" length on the vernier tools is so that you can use the vernier scale up to it's maximum nominal size.
For example, on the 48 inch caliper the sliding-part is 2.5 inches long, therefore you need 48+2.5 (=50.5) inches to be able to accurately measure 47.999 inches.
Try it and you'll see what I mean!
In forestry, we have our own D-tapes for measuring the diameter of trees. We do not worry about thousands. All I've ever used were to tenths. I prefer a Spencer log tape with a D-tape on one side.
Pi Tape - Pi-D is the Circumference. Nice tapes.
Safe travels & enjoy!
Nice additions to the workshop!
Thank you for sharing.👍
A great day for sure my friend.This project has been fun to see. All properly done with all the right materials. Great to see how many have helped you along the way. You do a lot of pro boneo and you are always getting that right back. Karma can be a great time eh. I Got my first job because After being shown just once I could still read a vernier. In the top drawer of my layout tools is a analog dial caliper that has never failed me for 50 years now it has never let me down. Electric, I have thrown a dozen in the trash in 45 yrs.The bezel has been cracked since 1980 and aside from getting a bit dirty inside doesen't effect it at all. In that same job of building Gas pipeline compressors I had a company set to use very much like this one. It could go as far as 10 feet. When using it it took 2 to handle it. My teacher and I worked well together. Everything that came to my Boring Mill was big. A 12 foot table with 3 tool holders. We called those diameter tapes Vernier tapes. Thanks a bunch Keith, Great post. Great pickups too.
I wouldn't say you didn't get much footage of the Gibb crane going in, you had quite a bit. Always enjoy your updates.
Enjoy your trip Keith. Be it be amazing. Your knowledge and preparation in indeed like a degree course in engineering tools and medicine s just love it. And indeed thank you for your time editing theses shows. God bless. Mate 🇺🇸🇬🇧👏👏👏👏👍🏼👍🏼👍🏼👍🏼👍🏼🙏
13:00 The scale goes to 50" so the Vernier will line up, they measure to just a bit over 48" ... Starrette made two modes, one is published to be actuate to +- .0005 and the other to +/0 .005"
If this is the .0005" Model they retail for around $7000 US ... (I think it is the better one) .. but even the cheaper one? Shops routinely squeeze a solid .002" accuracy out of them :)
The trick is to keep the "Standards" up in the office where the temperature is steady, and add or minus the difference, after checking them.
Neat old vernier caliper, i prefer dial calipers just for the convenience of not needing batteries and the quickness of reading compared to the vernier scales type.
Have a great trip sound like a good bunch of guys to be with, and as always thanks for the update video.
ALWAYS INTERESTIN
Safe travels.
23:30 I remember the old Scots guys used to call these a "Run-a-Round" ... These are surprisingly accurate!
thank you
I like verniers also. And slide rules. I still have my Pickett aluminum slide rule from engineering school.
Someone sneaked in and made the division lines and the numbers smaller on my caliper and both my slide rules!
I hope you consider some sort of video for the long road trips! A bit of a VLOG style showing off what you find interesting on the road would be neat, could be your foray into additional retirement content!
You sure picked up some awfully cool metrology toys there!!!
Well done Keith Rucker, you have some "real and genuine" FRIENDS.
17:30 I've used inside mics, up to TEN FEET long! ... we run a very tight piano wire down the center of the jon and line up the giant Power Plant, Steam Turbine housings with them,
Interestingly, oce you get close, the actual reading are not that important ... just the DIFFERENCE between them, as the housings need only to be centred.
Rock on.
Christmas came early
I enlarged that big vernier and it grew .003 to 2.285 on it’s way to my phone in North Carolina.
The extra inches allows for the vernier to function. If you were measuring 23.998 you would need those extra 2 inches on the scale.
0:32 The trick thee Keith, is to get someone there to JUST video, in these cases :)
The most impressive machine moving equipment I have seen was moving 7T PCB drilling machines with air skates that are essentially mini hovercraft fed with compressed air that just glide around effortlessly. The only consideration is the inertia of starting and stopping 7T of machine. In between one man can easily push and steer the unit.
at 23:36 i use pi tapes on my job. its the first time ive ever seen them on YT. nice!!!
Happy Monday Keith!😊⚙️🛠🥜👍👍👍👍✌️
Honest to god, as of the time I'm writing this it seems that 10 people have given a thumbs down. Are there really petty little Keith haters on here, so pathetic, these people need to get a life. Love the new Jib Keith.
Feel free to stop here in New Mexico for a visit. I've got a little shop where i make 1/8 scale steam engines as well as a small loop where I operate them. I'm 20 miles south of the I-25 and I-40 intersection.
❤Just watched Leo Tally Ho and he mentioned to come watch your channel. Your cool! The chain fall can be shortened so you dont have the annoying extra slapping around. Cut and weld the link. Peace out
Keith, I have 1 request that I'm sure many others would find of great value.
Please take some time to do a presentation of how you maintain a very clean/spotless shop. You are so organized!
I took various shop classes thru high school and got my Welding Fabrication certification in college. Each of the teachers/ instructors stressed compulsory cleaning after each session.
How do you do yours? Even your garbage can looks clean! I am particularly wondering how you clean the massive lathe in this video? Where do the metal chips, lubricants and scraps go?
That's easy, he just dose not do much work, if you want to see a "working" shop, with a real "machinist/welder", may I suggest you visit Cutting Edge Engineering, I think you will see the difference.
If and when you upgrade to an electric hoist, I suggest you configure it with a wireless remote control console. Having worked more than 40 years in shops that had WIRED control consoles (one was a traveling overhead gantry and the other a jib) I know first hand the inconvenience of that pendant control either being in your way when not in use or being just a little too short to reach sometimes when trying to position the load being lifted or lowered.
Keith- will you be able to call to see Leo 's Tally-ho on your road trip?
It would be great to see you two meet up and see the capstan working.
Best wishes,
Chris
Funny how us men talk about our inches, lol.... Like Keith keeps talking about that extra 2" from the advertised 48" LOL Your great !!
Nice 👍👍👍😎😎😎
almost need some thing like a Magswitch with electric actuator switch as a brake on the crane as it is so low friction
Those are some abom size calipers there
Keith, I sent an email to the vintage machinery website email about a huge K&T horizontal mill that looks to be in good shape going for $1500. Looked like something you would be interested in. Not my mill but thought I would pass onto to you.
My eye detects that Keith's belt is from the Philmont Scout Ranch in Cimarron NM. I always wanted to go there as a Scout, but never made it. When were you there, Keith?
No batteries and it always works. Unless it colder than 65 degrees. Or hotter.
Ken, I want to buy one of your aprons. Are they available anywhere?
❤️🔥
Wonder what light is flashing off the right side of the video
Just a light fixture going bad
FYI, how old is the vernier scale? Pierre Vernier invented his scale in 1631.
Are the calipers pitted? how would it happen like that?
can you show how you check the table if it is straight? i understand how to check the level but how to check the twist
Congrats on the nice measuring instruments. That 50” lol not only gotta be in a climate controlled environment, but also insulating gloves and min contact.
Have a 12 in Starrett and two slide rules. You know computers without batteries. 😊
Does anybody have a name for someone that could regrind a 10 foot American pacemaker lathe bed?
Yes, that would be a "lathe bed regrinder".
The shop temperatre doesn't really affect measurements since both the instruments and the parts are typically made of steel or other material with a similar thermal expansion coefficient
Good show Keith. Have a good trip out west, and please fix your flashing light fixture when you get back. Ed C
There is a light flickering on the top right????
Noticed that flashing. Maybe that says time for lunch?
😛😛😛😛😛😛❤❤❤❤👍👍👍👍👍👍👍
Why not a electric crane?
as long as the bed is straight level doesnt matter at all other wise how would all those lathes have functioned when they where mounted to the ship decks back in the day which arent level or stable on open sea ?
I’m calling it. 6 months from now there will be a videos titled “Jib crane too small! Time to upgrade!” The problem with having capacity is that it’s always just alittle less than the job you need to do. Nice job on the setup though, looks great!
