We used to get precision-made glass replacement parts ~2’ by 3’. All the credit went to the people who made and ground the glass. But we would routinely get packages with boot prints on the flat sides (deliberate?). But never a broken or chipped piece of glass. Credit to the (invisible) shipping department and the packaging engineers!
Doug Saying - Thus is How Things R DONE, If Ya Want Something Done Right DO IT Yourself !! Well maybe That Harsh ! LOL'S DIY - SHIPPING CRATES A Business Opportunity - Go in, Measure Twice Cut Once & Build the Necessary Sized Crate 4 Said Object ! Hey Keith, the Channel is Awesome !!
What a stroke of luck in finding those items and enormous kudos to the guy who recognised what he had and you needed! At that time you made that video appealing to anyone who might know where those pieces that you needed might be lying idle I personally thought you had very, very little chance indeed of finding them - how wrong was I!! That colossal find has to be one almighty step forward with this project. Best wishes.
I hope Keith bought a lottery ticket also.....the chances of finding these parts SEPARATE (i.e. not part of another lead attachment) were virtually zero. Incredible stroke of luck!
Keith, That was a heck of a find, Thanks to the folks that sent them as we are now going to get to see some more cool stuff made in the Vintage machinery shop.
That's so great when old unique parts get reunited with a machine. Maybe an old "need missing part" / "found mystery part" segment would be a good occasional feature on this channel or a similar one.
VERY thoughtful shipping crate and Doug has to be one fine person. I am very happy for you both. "Blessed are those who give without remembering and those who receive without forgetting." I don't think a large spur gear will drive a small worm gear if reversed at 9:20. If the intent of that pair is to have a 1:24 ratio, reversing them will be a ratio of 24:1 which I do not think will work or ever be needed. That means there can only be 3 combinations and not 6. Right? Sure hope the change gears you want to modify are not hardened.
yeah had the same thought. But maybe there is some extra gears somewhere that effectively route the drive through the change gears first and then the worms? But I dont see how that would change the total gear ratio either...
GENERALLY worm gears only work when the pinion is powered. Powering the ring gear USUALLY won't turn the pinion. Maybe there is something else going on like Gregor Lasser and Ypop Nun said.
Doug sure knows how to create a top notch shipping crate! Shows the value of what’s inside. Keith you looked so excited when installing those components I even got excited for you! Indeed the best part of the internet has been demonstrated here! So cool!
I'm amazed that he was able to determine that he had the gears from the little info that you put out there. No way would I recognize the gears from that. Also who remembers all the stuff they have that they don't use. You were amazingly lucky. And he's a great guy to have helped you out. Oh yea, like Clyde says... the box is a work of art... great job.
What a wonderful resource youtube has become. I watched Leo Sampson's latest Tally Ho video yesterday and saw he was using the threading device you kindly repaired for him. Hats off to you and to your most generous viewers who help make this a better world every day.
You have mentioned on this video and at least one earlier video that the three worm gear sets can provide six different ratios. However, I do not believe that you can drive a worm gear set from the large gear to the worm -- only from the worm to the larger gear. My machining experience goes back 60 years to when I was 25, and so I may be missing something, but wanted to pass along this caution. I much enjoy your videos -- they bring back fond memories of metalworking
I imagine the intent is to either power feed the table or turn the handle on the dividing head to feed the device, depending on the configuration of the gearing. Someone correct me if I’m wrong though.
Only a "gearhead' who appreciates those pieces of work would take the time to make that great of a box to ship them. Well done and a great addition to your K&T HBM treasure hunt Keith !
Remember Keith how your community comes together when you are in need of a part don't hoard the extras someone else may want to purchase those parts. Thanks for all your videos im a big fan.
What a beautifully ENGINEERED crate! Keith you were so lucky that Doug recognised what he had on a shelf was what you desperately needed! And Doug must be an awesome engineer if he does engineering the way he does woodwork. I won't ask but I am sure many of us youtubers would be curious to know how much that little lot cost you Keith !
They also act as a deterrent to pulling the cover in with the nuts, which you should never do. It strains the cover, strains the case and before you know it the shaft is being bent.
Hi Kieth, you should ask Doug to start a channel showing how to make part boxes 😁 that was really nicely put together so nothing would move, glad to see it's all coming together. Regards Richard
I am going to recommend your video to FedEx to demonstrate the proper packing procedure to the public. Most of the time it’s not the post office or UPS or FedEx that’s causing the problem. I packed a wall clock inside of two cardboard boxes with an insulating chamber between the two and shipped it FedEx to Missoula Montana. Made it no problem. This clock had Glass, weights, and chains . This guy went way above the call. Nice job.
Keith you are a very lucky ****, fancy being able to pick up not one but two sets of gearing for your project. It’s like finding one piece of a 1000 piece jigsaw and your subscribers supplying another 997 bits. Ok, so you have to trim a couple of pieces, but what a time saver. That box was the work of a tradesman too. Regards
Wow - Excellent packaging - so nice to see someone taking the time and trouble to protect items from the cowboys playing football with our goods, which we are paying them to transport. SO true the power of sodia media is great and so nice to see it used for good purposes. Great progress on the drive. Thanks!
The shaft I was referring to is called the auxiliary drive shaft and yes the 96 tooth worm gear is installed on the table screw extension and driven by it he 1 tooth worm for leads of 356 inch through 2918 inch leads it cautions you to lock out the table direction lever, that's what that knurled screw is for , or damage can occur, I have the 2H low lead and conventional lead attachments for my 1945 2H thanks Keith for the show
I would really like to see the low lead housing stripped of it's beige paint and repainted to match the mill. It jars my OCD every time I see it. So great to be able to put a call out and find the gear set. I can not help but think how had that would have been before the internet.
Such a unique video where it's one of those deals where you literally find the needle in the haystack put it under the Christmas tree and everybody freaks out over the wrapping paper! so perfect!
Low lead attachment complete will give 42,362 different leads from .0219 - 2918.4 inches with either the model H or model K dividing head....Both are 40:1 from the splined input shaft to the spindle of the dividing head. The difference between the model H and model K is that the model H is 40:1 from the crank to the spindle and the model K is 5:1 from crank to spindle....Cheers from Louisiana... Mike
Keith, if Im not mistaken you don't have to remove the nuts to remove the covers. Just loosen and twist cover and pull off. that's why the holes are bigger to the right of the mount hole. great Find for your K&T.. great videos..
When using certain leads, power feed will come from the table or the low lead directional lever. There is a thumb screw in the table trip and the LL directional lever to pin them in place. The table of leads has a Caution warning at the top every page telling you which feed to use.
I remember when you discovered that broken gear in your Wells Index mill. Somebody had one but didn't know what it was until they saw your video. I believe they gave it to you. I also think it was NOS. God loves you Keith Rucker and I certainly understand why. We, your loyal fans, love you too, Keith. Art
Gotta say, that’s a pretty amazing project, and is moving forward through the occurrence of several miracles. I’d never have thought this could all come together.
I would be keeping that box for the gear sets to live in. that is a great packaging job. You have a large audience of old iron packrats. the only difficulty is figuring out what half the stuff we hang onto actually goes to :D
Doug, that was a fantastic box you made to make Keith HAPPY, also us as well as we get to enjoy the parts you supplied, amazing that you recognized what you had and what they belong to .
Can you just imagine the size of worm gears and such on a NAVAL SHIP? Great find there and thanks from me to the youtuber that sent them to you as well.
referencing the worm gear set: I think you'll find you have to put the 'screw' gear on the driving shaft and the 'wheel' cog on the driven shaft, the other way round would lock it up.
Doug, Kudos for the job you did in packaging the precious gear for the K&T. Hard telling how many sets of those have wound up in the scrap yard. Thank you for saving that great American Iron.
Kudos for praising the sender and his packaging instead of bashing the carrier, parcels endure a lot of automated handling, if a heavy object is inside it’s coming out of a cardboard box
That is a really superb shipping box - like you I've seen far too much stuff just loaded into a flimsy box which has then been "carefully delivered" by the carrier......
Totally awesome shipping box! I do a lot of receiving and packing of parts and I'm constantly amazed by the thoughtless packing job that most people do. NO ONE seems to understand what their package will go thru once it leaves their hands.
I wonder how many of those gear sets are left in this world? You scored dude. Looking forward to the next video when you put all this together to cut a part!
An amazing gift and not only a great mailing crate but also can be used for storage Great video and I can clearly see that you are ecstatic about receiving this package
Ya that is WOW! My guess that table end bracket is the same color they painted liberty ship's and that gear set is a swap-meat long bomb that traveled through time from the San francisco navy yard directly to you kind of an eldridge thing It's power deffinatly fell in the right hands (Not that box at the end of raiders of the lost arc)
The pressure angle determines if a gear set will "overhaul" or not. Sometimes gear sets are designed so that they become a rotational diode. Cable winch and drums can be set up so that no brake is required most of the time. The book Keith likes by Spots goes over all this.
@@stancloyd You're right, but looking at the pitch of those sets, it doesn't look like those particular gears will work the opposite way...especially that 96:1 part...
@@Craneman4100w The 3:1 reduction may be able to work backwards. I have small worm gear reduction here with 6:1 and it will work backwards. Even though this is not ideal. As Stan said it depends on the pressure angle.
I'm looking forward to seeing you attempt to back drive that "1:96" worm set..... I'd be surprised if you could back drive "1-24". The "1:3" should definitely be possible though. :D
Yes, interesting consideration... maybe for some ratios you need to manually turn the dividing head and have it drive the table through the lead attachment.. Good consideration before you engage the table feed on a new setup.. Also, curious.. does this (or similar) mill have provision to drive the dividing head synchronized to the spindle?
@@windrk_6754 I think that it's a simple misunderstanding. Worms, and worm gears are almost never intended to be back driven. Even at low ratios they are very inefficient in reverse. It also doesn't make sense considering they provided a large selection of straight cut gears.
@ Landon Harris so you are " looking forward to a big crash of gears are you? Bit nasty methinks I'd just hate to see that mistake made and the bronze driven gear teeth get stripped right away when the machine was started. I'm sure Keith was talking to the camera without thinking because he surely knows that worm gears always are the driver, not the driven.
Hi Keith, Like you videos and I have experience running the machines that you have. The manual Planner is to old. But I ran Gray Planner the table was 10 foot by 30 foot this moved on long machine base. Planning steel we would get chips 9 inch in diameter and 3 feet long in long curl. Cut parts including 60,000 pound forming die to level one side. I have ran mills, boring machines, ginders, and lathes. I also ran CNC machines also. Worked for Boeing Aircraft for 32 years. Hope to talk to you someday. Jay
You still need the auxiliary shaft for certain leads or for driving an attachment without movement of the table....For helical gears, you should have enough to do that.. The drive gear for the auxiliary shaft should be underneath the table already.....Cheers from Louisiana....Mike
Before turning the teeth away on your spares please check the Rockwell hardness to machine a smaller gear pitch. Or you may have to surface grind or wire EDM the new teeth.
