Keith, I don’t know anything about machining, but I do find it fascinating watching you work. This Tally Ho project continues to pay dividends. Thank you sir, for the excellent entertainment!
in barely any time you'll be making the gingery shop.
For unique parts the metric/imperial debate finally reduces to one fact. The machinist is far less likely to make an error if they use the measurements their machines are calibrated for and they have most experience using.
Exactly as Keith was saying.
Nope. Magnetic backed dials work great for a machine that has no digital display or is locked to a single unit of measurement.
@@Fullion-CA What are magnetic backed dials?
@@ellieprice363magnetic dials are precision machinist measuring tools you can attach to your machinist equipment (lathe, mill,etc) either to measure the piece being machined ( during set up for example) or to the machine itself to measure the movement of the saddle/compound (in the case of a lathe). Because they aren’t original to the machine you can use metric or imperial dials on any age piece of machinery. Of course lead screws (the mechanisms that moves the saddle along the lathe bed or the compound in and out) are still going to be either metric or imperial.
Hi Keith from South London UK, I just wanted to say how much I am enjoying this series. I love that the geometry is all offset and its great to see how this can all be achieved with manual machining.
Morning from rugby UK coffee ,toast and Keith, Fridays sorted
Turning on that lathe and then using that press for broaching brings me back to my trade school days and then the beginning of the "job shop" days. I am no longer a machinist but still have the skills. After about 8 years in job shop and then gear hobbling for a few years with Gould & Eberhardt i gave my life a rethought and then became a maintenance mechanic/ technician and traveled with my company. What i have learned i never regretted and i can fix just about anything. I am 66 now and i am thinking of getting a metal lathe from a friend and perhaps i can help local people out with thins and make a few bucks to pay for the electricity and have fun...Time will tell. In the mean time i get to watch a guy living the dream.
This just amazes me to see this project and the amount of work that so many talented people are putting into this piece of Tally Ho's equipment. I'm sure Leo is beyond grateful . I can't wait to see this piece of history working on Tally Ho.
Good morning to everyone watching from Lincolnshire UK, time for a coffee ☕
Keith don't apologise for using your native language, most of my metrology is from before the UK decimalisation like me and my motorbikes & car 🙂
…and I’m very impressed how patient Keith is with the keyboard critics.
There's a story from Canada after they went to the metric system. A man went to a lumber yard and told the associate: "I want 12 pieces 10 cm by 20 cm by 2 metres long." The associate said: "Yes sir. Hey Charlie, this guy wants a dozen six foot two by fours."
@@peterhobson3262 in the UK today you will ask for 2 by 4s and get 47mm by 100 mm timber. But if you want sheet material, PLY MDF OSB etc. it will be 1220mm by 2440mm on the label i.e. genuinely 8ft by 4 ft but plasterboard, T&G flooring etc is metric i.e. 2400 by 1200 (or 600) just to make sure you are paying attention!
Something i genuinely don't get about metric. Is why nobody uses the decimeter which would hold the place of a foot in imperial. Metric was supposed to have mm, cm, dm, and meter. Doing stuff in several thousand mm is hard to visualize.
@@TgWags69 I guess in the UK we would say why don't you use stone and lbs for body weight I can visualise 14st 7 lbs but not 231 lbs, same as 5ft 10" is more meaningful to me than 70" or 17.8dm (1.78m). I guess the real answer is in metric it just moves the decimal point.
Oh! I am in Canada, I was in secondary school when we were forced to adopt the metric system. I love the "relationship to the human body" with the Standard Measurement System, and for certain things, the simplicity of the metric system to move between units is nice too. The reason for the change was that the S.I. (System International - or Metric System) was good for trade. But our biggest trade partner is still the United States of America. Then suddenly, communist Chinese goods flooded the market... which is No Buenos, in my humble opinion. Our family always supported the Democratic Taiwanese efforts.
As a non-machinist I really appreciate how you explain when certain dimensions or other attributes are important vs when they are not, due to later steps.
Thank you sir for expressing that measuring systems are different languages that we speak to build things.
Years ago I'd watch This Old House, couldn't get enough. I rate your channel, your personality and subject matter even better. Thanks and wishing much success!
I would love to see a @newyankeeworkshop collab!
Hello Keith, No problem in working in Imperial. I'm in the UK and I work in metric & imperial, due to my age I was taught imperial in the 60's then metric came along in the 70's and as most of the machinery I work on is American with German or Japanese engines I end up working in both, I use metric for fine measurements down to 1mm any smaller I go thousands? Large measurements feet, yards or miles ?
Hey Ho. Makes life interesting.
Regards Richard 🇬🇧
Richard, me too, having been a scientist most of my working life,m everything was metric, but inches are no issue either, my swiss made mill has an imperial lead screw so that really mixed up. DRO makes life a lot easier. The fun one was working in Australia, I had a kids school exercise book for notes. On the back was a list of metric units and a note that time was “ unfortunately” metricated. Last year I saw a clock in France with the dial calibrated in ten hours. Um, where does one go with that?
@@johnsherborne3245, Next thing we’ll have ten months in a year! Lol
@@Hoaxer51It's worse to have ten days in a week, imagine waiting 8 days between weekends 🙄
@@Hoaxer51 what a good idea! Blame it on the EU/brexit/ election?
@@johnsherborne3245,Heck yea, may as well get your money’s worth out of that thing!
Remember to do the bolt hole radius to 3.284 inches as you machined the capstan base to, not the 3.248 as showed on the blueprint diagram.
Watching to see if he addresses it. Wonder when he did this versus the fact we are watching now.
3.284 - 3.248 = 0.036"
That is a tad over 1/32" error. You would typically drill 1/16" oversize for a bolt hole, so he should be near the fit up tolerance as is.
3 and 33/117 inches you mean. Much more convenient for those Brits then the metric equivalent.
@@joshua43214The holes in this plate are 12.5mm for 12 mm bolts. It won't fit if he doesn't correct this. Not sure if these holes have to match the motor flange (expect they do) so he may have a problem further down the line.
@@bartboosman953How about 3 and 11/39 inches?😂
Thanks, and of course I will comment! I've never done any machining work at all, but it is fascinating to watch folks do it who are willing to share their expertise.
Wow...they give you plus .05mm on the drawing, and you go and take an extra .000031" in conversion error. Nice job. (The preceding portion of this message is what I imagine someone on the internet actually telling you with a straight face, because "they know the truth" of machining) With the sarcasm turned off, I want to say I love your work. I am a machining student in Spokane Washington and this kind of work is inspiring.
Sensible to work in your familiar units instead of SI. Less likely to make a mistake. And the original capstan probably used imperial too.
It is an enormous pleasure to me to watch Kieth machine something like this piece. His trained fingertips run those micrometers perfectly. It is trivial to change the micrometer reading by several thousandths with bad technique. The joy to me is that this part _will_ perfectly fit the parts being made in Millbrook, Torpoint, Cornwall, England, which is 4,250 miles distant. In addition this is far from a trivial part to machine. Wonderful. Just wonderful to watch.
Keith!
Many peoples, several different geographic locations, a collaborative effort. You sir, are a brave man.
I always think of the 1999: NASA's Mars Climate Orbiter failure, A NASA review board found that the problem was in the software controlling the orbiter's thrusters. The software calculated the force the thrusters needed to exert in pounds of force. A separate piece of software took in the data assuming it was in the metric unit: newtons.
I’ve been watching the Tally Ho restoration from the beginning. And I do have to say, it is nice to see all these other channels get some light and recognition from it.
Hopefully your channel grows, as well as Windy Hill and Dave Clark’s.
There is a lot of decaded knowledge, skills and experience on all your channels that deserves to be shared.
couple thoughts, one, face a side then turn the od better than half way, bore your through hole all in the same setup, then flip it and use the bore and turned od to get it dialed back in, no need to set up on an arbor and the more features you can do in a single setup the better your part will be (saves time too) and lastly oil the backs of your keyway broaches, helps prevent them from fetching up on the shim or bushing and causing them to dive.
Yep. Two lathe setups and done.
I am interested to see you are going to bolt this to a 'rough' casting face, in my ignorance I would have 'lightly' skimmed' the casting to ensure it had no high spots, as I would expect cracking if uneven forces are applied via the bolts, can I ask for the rational?
You are right in my opinion. It would have been advisable to have a flat surface. Might even have been better to have the casting made full out there. And mill it perfectly flat. Not on a lathe…but on a milling machine.
I would put some long smooth shank bolts in the capstan base, then wax the iron, build up a little perimeter wall in plastilene, and cast a piece of plaster or urethane resin against the bottom of the base. Pull the bolts and pop the plaster off and you would have a pattern that the top face of the adapter has to match. If you have a pantograph, you could use the plaster to mill the surface down to match the pattern.
I couldn't agree more. But I know nothing........
As Curtis at CEE would say “bananas”!!! 😂
Kurtis
Kinda makes me miss my 33+ yrs in a machine shop. It was hard work but quite satisfying when you got it done correctly. We used to say, If it were easy, everybody would do it..
I’m an electrician. I’ve worked in machine shops. Installing and repairing lathes and mills. I’ve always been fascinated with the work the machinists were doing. It is just amazing.
Had two years of HS machine shop in the '50's and loved it. Great video.
Fascinating work. Found you through Tally Ho. Thanks for sharing this with the world. 🇨🇦
In 1987 I started working for Dominion Engineering making wood working machinery in England, West Yorkshire, I’m now an HGV Mechanic, but find your work fascinating. My great grandfather was a pattern maker during the 2nd world war, it’s funny how this tally ho project is bring all my interests to one point and making all the dots connect in my life. I think technology and progress is a wonderful thing, but love the delving into where it all came from.
After watching you face the first side and hearing the chatter along with the drag out marks of the tool and then the drill chatter , it’s a good indication that the spindle bearings are loose!! 40 + years as a Journeyman Industrial Machine Repairman leads me to that conclusion 👍
How difficult is it to replace the spindle bearings
This ^^^^^
Very plain to hear as the spindle starts with torque and a squeal, the preload has failed, missed the 2000 hour checks a few dozen times.
@@gus9675 They can be adjusted?
@@gus9675 Since it has a geared head, most of that is going to need to come apart. Maybe he could be lucky and with adjusting the preload it might be acceptable for some more time, but bearing replacement is a big job.
Yes there’s definitely something wrong. He should not be getting that much chatter, especially on cast iron. A relatively simple spindle bearing pre- load adjustment should fix the problem.
I don't know that it's my end only but I have all kind of weird audio artefact and they are repeatable, so it's not my wireless headphone setup and interference. Great project, I can't wait to see it go forward.
Love the Capstan Project
looks like I am the first to comment.
I support Leo in his fantastically high-quality restoration. this capstan will be the crowning piece.
SUCH a lot of work has gone into it. I am so impressed.
At some point there was an unknown hero of machining who figured out if you replaced the exciting bar with a boring bar the results were more predictable.
Dad jokes aside, it's always fun watching you work on projects.
Don't know whether to vote this up or vote down. Well played.
Nice work Keith. I enjoy you commentary that talked about when to be concerned about run out, when not, and how to compensate by executing the proper steps during the turning to get the final part compliant to the drawings tolerances. Thanks for sharing!
.Milling that half-moon slot is whhat the K&T 2D was born to do
Hi Keith. In the UK we call feet and inches "Imperial" measurements. At school I was taught Imperial, that is until "metric" came in circa 1970. So I am used to both systems.
Good morning Keith. Gave a great weekend. Thanks for the videos.
I learned lathework and metal working 44 years ago in technical school in the netherlands. I liked being able to form hard metals into the shapes you want to great precision very much. I enjoy following the proces of making parts for the capstan and think this craftmanship is priceless. Looking good; can't wait to see the capstan in function.
Hey Keith, I might be old school but I work in inches too. I can visualize 12 inches in my head but I don’t have a clue what 12 meters looks like; same goes with gallons vs liters. Lol
I still say Leo told the designer he wanted the Capstan modernized with an electric motor, which he did but didn’t think it through. Originally there was a hole in the deck for the base, “what’s that, like 4 inch diameter?” plus the mounting bolts. Now with the motor mounted on the bottom of the base a large opening will have to be made in the deck to accommodate that adapter and motor. I said this before and someone said no the motor would be mounted lower and just a shaft would come up through the deck but that is obviously not the case. If he hasn’t already figured it out someone needs to call Leo and say hey, do you realize you will have to cut a damn big hole in your deck to mount this thing? I don’t think the necessary support to allow a large opening has been designed into the deck structure. I hope I am wrong but this might all a waste of time.
Looking at this from England 🏴 good to watch
Thanks Keith 👌👍
Very enjoyable to watch this machining being done. Your explanations are clear and precise like your work. Old school pride of craftsmanship shows throughout your videos. Leo has once again picked the right partner for the job. The Tally Ho project has been a showcase of American know how.
Did anyone else hear something that sounded almost like a voice when he backed out at ~10:00? 😅
Another audio source is definitely bleeding through. I am guessing that his memory media is acting up allowing a previous track to bleed through.
Subliminal messages, everybody goes to patreon now.
That is the sound of the souls of foundry workers being released.
16:32 mark had me laughing
Thanks Keith. That's a ton of work in that thing.
I live in the UK and I called 15mm pipe 1/2 inch and the fittings to go on it 1/2 inch. that's what I grew up with imperial measurements, used to tell my son a measurement he would say what are you working in millimeters or feet and inches our tape measures have both mm on one side feet and inches on the other good for a bit of confusion
Cool beans! I assume you get to go sailing at the end of all of this?
Am I the only one who seemed to hear the lathe making noises that sounded like words in a foreign language? Great work Keith! Edit: actually it may just be some audio glitches either in the recording or from my computer.
From a naked blank and some line drawings to a piece that will only be seen by the builder. Really awesome work.
Thanks Keith. I finally understand which way up the whole assembly will be! I had assumed the spindle / sleeve pointed "up" but now realise it points "down" and in fact will protrude down through the deck.
Great watching things progress! 😊
Old blokes just know how to do it right.
I can convert most measurements in my head - I know that a inch is about 2-1/2 centimeters (exactly - 2.54 cm) It's not hard to go back and forth.
You work in inches because you know it _better_. That's perfectly reasonable. Folks that work metric that have to work on inch parts convert to metric to do their work. It's perfectly reasonable.
I am thankful that I get to watch you, Adam, Curtis, and others share your work with us so I can get my "fix", because I don't get to do that. Very much appreciated.
I grew up learning metric and imperial, and, like you I convert in my head. I can estimate things easily in both. I find that I use metric more for fine work because I worked in an industry with tolerances less than 1 micron
Hey Keith, great as usual. 100% on the English/Metric discussion. I use both all the time. Anybody from the UK complaining...just remember, they use MPH on their freeways...at least when I was in London last I was confused because I saw 60 on a freeway, and said "Wow, pretty slow...60KPH? They said "no, 60 MILES per hour". So I don't want to hear that Metric/Imperial Argument from them. LOL.
I did notice you have some audio issues going on. At first I thought the Dura-bar was sending subliminal messages @9:54, almost sounded like it was saying "English units are the enemy". LOL
Then I heard it more often. I heard it at the Arbor Press, and quite often at the lathe. Almost like there was some kind of interference with your mic, or there is a issue with the mic interface...lots of compression artifacts.
There are two things in Britain which are regularly measured in imperial measurements: distance in miles (and speed in MPH), and pints of beer in a pub (and milk in a bottle). Oh, and we don't have freeways. Can you name the other two countries on the planet that still use Imperial? The fact that the USA is still using Imperial shows how incapable your politics is of working. It's a massive struggle for your crazy country to change anything, ever.
Love your work Keith, plus came to laugh at the inevitable comments telling you that you're doing it all wrong!
I like this project a lot, thank you.
Watching your expertise and experience from England and Sir you make an excellent video with as much precision as your end products. Brilliant to watch you creating! Thanks for sharing
Really like you explaining technique and obviously every machinist has their own as long as the end result matches the drawing! Hat off to you Sir
Something's a little weird with the audio in this one but no big deal, good to see the project is coming along nicely
I’m glad to hear that I’m not the only person hearing some weird… not sure what to call them.
Same here. Occasional words are scrambled like a record spinning backwards.
I second “don’t worry about using inches” when and where Tallyho was built inches were the thing.
Keith, I apologize for last episodes comments. Without knowing the details of the assembly, I criticized your workmanship for lack of precision. I had ASSUMED that the motor would bolt directly to that drilled pattern and there could have been a fitment issue. I was wrong.
Keith did mention in the previous capstan video that he was going to be making this mounting plate. Guess you missed that part. It was also discussed at length in the comments.😂
Another English fan here, I love your rich 'Suthernn' accent Keith. Keep posting these treasures, and many thanks.
As an American, I too enjoy his foreign accent.
@@ottomakers, Especially when he talks about oil! Lol Sorry Keith, just having some fun at your expense, I really do appreciate all that you give us.
To anyone complaining about him not doing this in metric... consider how much it would cost to retool his lathes to metric dials; and obtain all the different scales/dial-indicators/micrometers/etc. in metric instead of inches.
It's all about tolerances, if he can hit them as requested on the print, the unit system is irrelevant.
It’s a good thing Leo only paid $1 for that boat because he’s going to have a small pile of money tied up in converting the capstan to power drive. Nice piece of machining work on this one!
Let’s face it: Leo paid about $30,000 too much.
Followed the Tally Ho since the beginning. No, I don’t care.
Leo bought history and a bunch of folks rallied behind him. It's probably gonna be donated to a museum or some such.
Looks great! And looks like a lot of work.
Really enjoy watching your videos, like always another great video and thaks for sharing!
Thank you for another great video. Cheers
As long as you hit the dimensions within specified tolerances, who cares how you got there. And as your shop is mostly imperial, it makes sense to work and think in imperial.
1:42 Back when Canada adopted the Belgium made FN Rifle (Dubbed the Canadian FNC1A1) , we silenced to manufacture it ourselves. ALL drawing were converted to Inches, before anything was made here, Some publications still call the C1A1 "the inch pattern rifle"
Thanks for the video. dedication to precision is fantastic
I’m a long time subscriber and just wanted to say that your work has always been interesting and you keep going from strength to strength. You are such a high quality youtuber now, one of the very best in your genre. I’m metric but so enjoy watching you work in imperial. Maybe one day there will be an autonomous robot helicopter on Mars built in metric, it could say hello to the imperial one that’s already there…
When you moved the cutter out at around 9:53, the chatter almost sounded like a female robot voice haha.
Interresting project, thanks for taking us along :)
Watching further, there's something up with your audio, either from the camera, software or some audio settings. Sounds like a mitch match between audio sample rates.
Yes, but the odd noises keep on sounding like voices ... no idea what it could be
@@timbergel8147 Yeah, it almost sounds like an AI sound replacement/assist thingy, that whenever there's a noise below a certain treshold, it tries to replace it with a human voice/sound. Really odd sound problem.
There is DEFINITELY something that sounds like distorted voice fragments getting overlaid over the video at certain points.
Sounds like he is using some software to "clean" up the voice commentary, very strong auto-tune like throughout. And it seems to do some weird stuff to even make the lathe talk to us.
I really enjoyed this video. Your descriptions of what you're doing is very educational. Thank You.
A hint I used on boring bars that were doing a Precicon bore but I had to have a long thin carbide bar - chatter. Solved by super glue a right-angle bar to the back side that fit in and it kept the chatter out of the long extension I had to use. The bar comes off with oil. Kept it with the bar as a reminder.
Keith, you are the "Captain" of your shop.
Keep up the good work.
Keith, as long as your inches to metric conversions are good and you keep speaking in thou it's all good 👌🏻 another fine job sir 👏🏻
some exorcist sounds around 17:35 while you're broaching... scared the crap out of me!
I assure you that I have enjoyed your videos about capstain absolutely as much as I've enjoyed any of Leo's videos. It matters just as much. And you completely understand and know what you're doing. That's obvious. Very well said and done. Thank you so much for your support in Leo's dream. You're making such a HUGE difference!! Thank you.
Thank you, as always, for your content, and patience with those who choose to criticize. Often, it is better to keep one's mouth closed or fingers off of the H.I.D. (human interface device), and be thought a fool, rather than open it (or actually use the H.I.D) and confirm it!
Lol Thank you, that was right on.
Thank you so much for sharing your knowledge. It is truly fascinating to learn some machinist tricks and the know-how of processes from someone who truly knows their trade.
thank you Keith we appreciate you making this material for us to enjoy!
Great job
Thank you for sharing.👍
Love your work Keith.
Thank you Keith!
Nice to see a master at work good job Keith
A great video.
Great video thanks for sharing
Excellent as usual.
Dave thank you for making these videos these videos! 😊
Im not a machinist but i thought i knew machining from my military trade school training. Watching this shows how much more there is to it that i was never taught
Nice work Keith.
Thanks for sharing the process.
Have a great day.
Thank you
Nice work.
I'm really enjoying your vids, and look forward to them almost as much as Leo's
I'm native metric, but my Dad was native Imperial. When I'm working I'm in metric cos base 10 and everything's related, but when I'm DIYing I always revert to imperial as it's more intuitive and visual
It's best to use whatever is best to use, and Imp is very precise, an inch is exactly 25.4mm after all.....🤣
Hi from Boston and thanks Keith!
thank you Keith
This has been one my favorite videos I’ve seen on your channel. Really shows off your machining skills.
Found your channel on utube, I am watching Tally Ho from the beginning and the rebuilding of the Capstan project with the making of the new casting ! This capstan has become a real project for everyone!
Thanks Keith
I love yer Gerstner boxes
The original capstan was built using measurements in inches - so your work is authentic and true to the original!
@@paulcopeland9035 Because the original capstan for Tally Ho was made in the UK about 1910, and the UK only used Imperial measurements then!!! The UK still has not fully adopted the metric system in 2024!
Nice job.
