Morning Mr.Pete
I love waking up to your videos with a cup of coffee!
I absolutely appreciate you making these videos. The days of "crank man" machinist were the days to let your talent show! Fun, Fun, if only there was a school that taught "traditional" machining+tool and die.... those were real skills, No $900k milling center to do the work for you!
CNC machining still requires talent to do correctly, it's just a slightly different kind of skill.
@@firearmsstudent I'm thinking like a "Woodwright's Shop" for machinist.
"Grand-daughters" nail polish is really Lyles nail polish, but it's only for weekends. :)
Once again our Mr Pete shows us how it's done. None better and none finer!
Mr.pete thank you once again I love your channel
Thanks
Great video Tubalcain. It is nice to have the machines, to make the tools, to make the end products. Can't wait to see that 15 hole plate in action.
Very nice, and I loved seeing you use that old flat-tipped to install the plate at the end! Thanks for sharing photos of you and your brother..a nice treat. Thanks, Mr. Pete! :-)
That is the first time I've seen that method for centering the table off the Spindle! Very nice
Yes, if you are talking about the indicator mounted to the rotary table, this method "corrects" for the rotary table's bearing runout.
@@bobvines00 exactly that.
The nail polish makes for the prettiest rotary table around. Thank you Mr. Pete, never thought of putting the indicator on the rotary table and indicating the quill. VERY useful!
THANK YOU...for sharing. Watched and very much enjoyed.
Another great video as usual. I've enjoyed all three parts so far. Thanks for putting these videos out for all of us. Dan
Excellent per usual. I love the time saving of centering the plate with the arbor.
_Dan_
Wow I have never seen anyone use those old timey ratcheting screwdrivers. You always see them at every garage sale and wonder who uses them. Now I know it's Tubalcain
Looks like it will be a good day now !! Thanks, Cliff
Nailed it again Mr. Pete! Thanks for sharing!
Your erudition is exceeded only by your expertise. You sound just fine to me. BTW: Really loved the indicating on the spindle....very clever. I learned something today, thanks.
Thanks, I love that word
Great results. I did a similar project, except I used a small cnc machine to layout the holes. Worked ok. Thanks for all the videos.
Very interesting. Nice work. Thanks
Mr Pete. I had a few awesome shop teachers back in late 70s and Early 80s but wish you had been one of them. Love your channel.
Thank you very much
That arbor is a good trick.
As a beginner I did not realize you have to lock the table at times on the mill and messed up a keyway. Good tip
Frank
If I did not know that Jan was older than you I could still pick you out of both pictures. Thanks for showing them, would love to see more.
👍👍
Enjoyed the video. Good explanation mrpete. I look forward to the next video.
Great content, thanks Lyle
Lyle, thank you for this video. I learn something from every video, even if what I learn isn't directly related to the "title" of the video. Watching skilled Machinists work, especially with manual machines (like I have at home), is always a learning experience.
👍👍
I've been watching the series and like a true shop teacher you show different methods. My favorite is the rotary table. From past experience on a manual machine if it's tight, i get the best results.
Yes
Now I know the secret of the plates. Again, I know this year has been a busy one for you. Thank you for the many videos; I have enjoyed the all. Again, sorry for your loss of your brother; I have three and they are all younger than me! May God bless you with health this coming year, Greg.
Thank you very much
What an excellent series. So far I've only done gear cutting in plastic using a Chinesium rotary table and single tooth flycutter. I should make a video on that. I hadn't considered using the rotary table to make my own indexing head. Thanks once again for your devotion to many these many videos. They will serve as useful instructional material for many generations to come.
Thanks
This is a great series of videos and I am enjoying it a lot. Thanks for the video.
Thanks
Good video. A good example of the time for setup is far greater than the time for the actual operation.
I know the challenge of replacing batteries in phones and tablets. I had to replace the battery in an Android phone and tablet in the summer. The devices are not designed for this so it is very time consuming.
Dave.
Hola, I enjoy very much your class. Maybe is safe to say that I don’t want to miss a single period. ;)
On the Yankee screwdriver-- keep your fingers free & clear of that spiral mechanism.... I still have a mark where the side of my finger got pinched.... Hurt like the Dickens.. And thanks for sharing the use of your Walter rotary table. I only have a small Rockwell Mill and don't think I'll ever find a table for that machine. Sorry I cannot make it to Lost Creek today.... Too far from NJ for that kind of visit.
That happened to me when I was seven years old. And I made sure it never happened again
Thank you.
Thanks for sharing sir..
Good job.
Gesundheit, mein lieber Freund! Technology is like the brain, i hasn´t a languaje! I enjoy all of your videos. I'm only 68, so i have still a lot to learn! "Mientras haya hilo en el carretel, a dar puntada!" (so far is yarn in the spool, keep sewing!)
👍👍
Good video mr. P, the use of the rigid centerdrill is smart,and using the rotary table should produce pretty accurate results. You might have gone from hole to hole to check your accuracy. Some of us are just curious. And someone. Mentioned about the distance from center increases accuracy. I'm very happy with the options given to us so far mr. P. Great job.
I like the pictures of you and your brother.
Thanks
Great to finally meet you today,wish I could have talked to you more. I know you had a lot of people wanting to talk.
Thank you, I had a good time today
Mr. Pete everyone misspeaks my wife tell me to let her do the talking which she is very good at.
Love the overalls!
You did a nice job on the tractor part
@@mrpete222 Thanks!
The further apart from the center the more precise because it's more forgiving on the tolerances of the index. The tolerance causes half the angular error if the hole is twice as far from the center.
Good point
Looking Great. I little back ground ambiance. Merry Christmas.
Merry Christmas to you and your honey
@@mrpete222 Thank you Lyle. Merry Christmas to you and all your wonderful family.
thats very cool! and im a little impressed about the iphone
Yes
Nice
Gesundheit! Your German is excellent Mr. Pete, Good morning from Gloucester, MA
I haven't used my Yankee screw driver in years. I saw you use yours putting in mounting screws. Got mine from my dad.
I had not use mine in years either. And mine was also from my father. But I got a bunch of them. Batteries never go dead
@@mrpete222 I always viewed them as automatic finger slicers. I never use them.
It's amazing how Grand Kid noise is so joyful as compared to the "spite mower"!
Yes
Great video as always Mr.Pete. I think centering the plate on the rotary table is essential, but not so much the rotary table to the mill spindle. If the rotary table is locked to the milling table, and your spindle is above where you want the radius of the holes on the plate, the rotary table will just sweep the plate round underneath Inna perfect circle. It doesn't matter if the rotary table is not centered to the mill.
Exactly! Mr. Pete's method of centering the table with the axis of the mill was worth watching. However, I don't think that step was necessary in this case.
Love that double ended shifting spanner.( crescent) . Double butchers tool
Yes, they can be set up for metric one end and imperial t’other. Very useful. Regards
@@petergregory5286 -- Just get yourself a FULL set of wrenches in 1/64" increments and you'll never need a metric wrench... :)
Grumpy OldMan Then you would always lose the 25/64” instead of the 10 mm wrench.
It is said to have belonged to the great grandfather of the phantom menace.
Lyle, I just changed the bat in my iphone, too! Just like being a machinist, if you have the right tools, preparation and patience it's not that tough! It did get me wondering about what it's like to work in the iphone factory though.
I did two of them of them. The first one took an hour, the second one took 15 minutes
Another interesting video, thank you. I would have liked to have seen you showing the consistency of the spacing using the pins like you did in the previous video, perhaps that could be added to the next one?
Another great informative video, I hope to have a mill some day to be able to do the things I see you do, ( if only I can remember them all by then) lol.
Yes
Stripe shirts, jeans and coveralls. Hand-me-downs.The days of imaginations and few toys. Fun times. Wouldn't want to repeat it again. I often wonder how I survived it. Refuse to enter my second childhood, still busy having dun in the first yet.
Good morning Lyle
Another great video. I guess I'm so bass akwards I didn't notice you misspoke, but I understood what you meant. 😂😂😂
lol
Lyle. Was that a Stanley "Yankee" screwdriver I saw you use. Have not seen one used on TH-cam before. I have one, what a super tool.
Would slightly countersinking the holes really be a problem? I'd think it would help the pin go into the hole and I'm considering doing this on my plates for when I'm cutting gears.
Thanks for the video.I see it every day Here is a fan from Puerto Rico
👍👍
Thanks Professor, I appreciate the sharing of experiences, both the machining and the photos of Henry' s great uncle and his grandfather. I wonder if your dad said you and Jan made a lot of noise?
I bet he did. Lots of fire crackers, hammering, showering, shooting, loud engines, and just plain having fun
I have to agree with you about battery replacement on phones these days. I absolutely HATE the new phones where you can't simply pop off the rear cover and quickly swap out the battery pack. When I was on a trip involving long flights (like when going overseas), I would carry a few charged batteries and an external battery charger with me so that it would be less likely that I would end up arriving there and not being able to contact my ride or whatever because off a dead battery. These days, you can kind of get around that by having one of the external battery packs that has a USB connector on it, but it is a bit clumsy to use your phone that way. All of this is because the phone manufacturers want to save a millimeter or two and say that they have a thinner phone than their competitors. Which is totally stupid as far as I'm concerned since it just makes the phone more fragile and difficult to hold, so you end up buying a thick rubber cover / armor for the phone so that it won't be so thin, slick, and difficult to hold. I would be perfectly happy with a phone that is 1/2" to 3/4" in thickness.
Everything you said is very true. Are use one of those external batteries on trips
@@mrpete222 -- If you have any old laptop battery packs, it's possible to disassemble them and remove the cells that make up the batteries. I've done it on a few and they have always been either the 18650 or 26650 type lithium batteries (usually the 18650). There are battery packs on eBay that take these batteries and have the charger and power regulator built into it. They are about $1.
www.ebay.com/itm/Backup-External-USB-Power-Bank-Battery-Charger-DIY-18650-Case-Box-for-Cell-Phone/291793872612
Combine that with a small USB card / plug mount 3-LED light that will plug into the USB port on the power bank that is attached to the ring that comes with the power bank and you've got a good spare light also and don't have to try to use your cell phone for the light.
www.ebay.com/itm/Portable-2Pcs-Mini-USB-LED-Light-Pocket-Card-Camping-Lamp-Mobile-Power-New/254221879173
Often, when a laptop's battery "dies", it's is not every cell that has died, so if you disassemble it, you can still get quite a few of the cells to work.
Unfortunately, mobile power banks like this will not help you if the battery on your phone has truly died and cannot accept a charge. I've seen phones where the battery shorted out or whatever that made them so dead that you could not even get them to work when hooked up to an AC charger.
With regard to the school teaching useless stuff, our local high school teaches the Japanese language. There's only about 4% Asian around here and even fewer who are of Japanese descent. I've seen students who have taken 4 years of Japanese and still could not carry on a conversation in the language. All it seems to do is make them want to watch those stupid Japanese "anime" cartoons... :( I'm in Texas, so the only secondary language that would actually be useful to know would be Spanish. But I already know the two most useful phrases in Spanish -- "Dos cervezas, por favor" and "Baños?"... One eventually leads to the other... :)
I find your videos to be intresting ,can you do a video with 77 holes as it is an composite number
Mr Pete I noticed that the chuck key for the Jacobs Chuck had a "barrel" of maybe aluminum on it. I think to make it a little easier on your hand to tighten the chuck. How did you do that? I would like to do the same for Jacobs Chuck on for my mill. Love the videos because I always learn something new.
Watch my shop chips number 216.
here in Canada we call the crescent wrench the "Saskatchewan socket set"
lol
Is there a crack above Y dovetail on your mill??
Gesundheit! Und viel Glück! ;)
lol
enjoyed....regarding the Iphone, I carry the phone in my back pocket...over time the charging socket gets packed with pocket lint and the battery’s charging connection is blocked, a needle and small tweezers can get it clean....
Yes, that happens to me all the time. And I carry it in my front pocket. I Call it bellybutton lint
It's been awhile since I seen somebody yes a Yankee drive
Yes, that’s why I used it
Good video. LOL on cell phone.
Yes
That one must have had a reasonable high satisfaction factor, though maybe not as high as replacing the phone battery. I replaced the screen on my Kindle and that gave me quite high brownie points in certain company even if it was a relatively simple task. I’d like to try the battery in an IPad but having seen someone strip one down on TH-cam, but not reassembling it, I think I’ll give that job a miss. However, back to the work at hand, being able to produce a set of reasonably accurate plates whenever required could be very useful. Regards
What name brand is that crescent wrench
Question, I know your DRO is one of the older ones. However on the more modern ones like I have could you do a bolt circle with the number of holes and the diameter?
Mine is too old for that
Good video. iPhone battery was a fail when I tried it last year ☹️
Yes
When looking at the photography of you and your brother from the mid-1940's, I wondered if a digital photographic image generally transiently viewed by others only on a digital display device, will be available to others 75 years from now? Even if stored on an optical disk, will it be readable by any device 75 years from now?
In contrast, The National Archives estimates that the life of a silver halide photographic (black and white) image is more than 300 years if properly stored.
it would be good if you could show us how to do the calculation with the minutes and seconds for divisions which are not even numbers
For the nNth hole (starting at zero) of M (best to calculate each hole individually to not let rounding errors accumulate)
360 * N /M integer part of the result is the full degrees.
For minutes, take the decimal part (ie subtract the full degrees/integer part) and multiply by 60. The resulting integer part is the full minutes.
Repeat for seconds (ie subtract the integer part and multiply by 60) integer part of the result is full seconds
Or get a "scientific" calculator (cheapo for 3-4 bucks on aliexpress does it) that does degrees/minutes/seconds (look for button with ° ' ") and type in 360° * N / M = and it will spit out the result.
If you have a modern DRO bolt pattern function works faster then rotary table.
That is covered in the next video
To make life easy, use a 135 degree split point machine stubby bit. Then you don’t need to drill a starter hole and drill it through later. The stubby bits are sturdy the split point doesn’t wander, and has low cutting pressure. I’m surprised that it’s not being done. I’m also sure you know all this.
Good morning, Looking good with the plates. Hope the I phone survived,
Could have used your stubby drills instead of the center drill? No criticizing just curious. Thank you for all you do for the machining community.
11:23 Why use a center drill vs a standard 1/8" drill bit ? Thanks.
Because rigidity is your friend and a 1/8 bit isn’t very rigid, especially with no punch mark to keep it from skating on the flat surface.
@@ricksharpe6895 I thought this might be the answer but had to ask. Thanks
could have been nice to put the pins in, see if the errors were different than previous method.
Sir, what happens if we have a gear with say, 7 or 31 teeth? I have seen gears like this in old clocks and watches, prime numbers, what will be your weapon of choice?
Just do the math and then proceed just the same way. But your spacing will not be in whole degrees.
@@ClipperDays that`s a question about preference.
Prime numbers teeth is always an issue in gears making. Some machinists prefer a big template disc, some prefer cnc, some just avoid using prime numbers and i know a watch maker who prefer just punch mark on the material and solve the problem by diamond files, every method have their good, bad and ugly side. It is up to what tools you have and what skill you have, who knows? The reason why i would like to hear his comment becase he had all the tools, skill and actually try and demonstrate the methods he mentioned. “He had try it all” experience of a seasoned machinist is the key😄
i was hoping you were going to proof your work as you did with the previous method, using the pins and measuring with a caliper. Nevertheless, great video, as always.
hmmm, Arkansas speed wrench? We called the Oxygen-acetelyne apparatus “ Blue Wrench” it was “adjustable” also 👍😷
lol
Aka Gas Axe
Nice to hear you speak German, it was not bad. 👍
lol
Lyle the Dumcaugh that crashed your rotery index table it can be tig welded with a tig cast repair welding rod 😁😎.
I watch quite a few videos on TH-cam etc...and machinist type videos are always the most patriotic with the American flag usually prominent in the shop...why are or, is it that machinist have this sense of "nationalism"? (Which I think is fantastic) ...I wish more people and videos had a sense of "nationalism" perhaps England's recent election suggests more of us feel this way.

Apple don’t charge that much for a battery replacement. Think it cost me $49 including installation last year.
I've put a lot of screens and batteries in iPhones. It's not generally that difficult (though the 4 sucked). It's about $10 to buy the battery generally and about 20 minutes and it's interesting to do. Screens take a bit longer but are like $25 for parts, Apple charges half the cost of a new phone to do that.
13:45 too much Folgers?
Mr. Pete has the best coffee.
Rest in peace
Also don't try to change a pacemaker battery at home ether
lol
I'm 79 and had a pacemaker put in last month, they said my battery is good for 7 years.
Arkansas Socket Wrench, identify as All Sixteenth by as Adam Booth.
I see yours is both metric and imperial.
Yes lol
You don't have to take the sector arms apart young man.
I'm shocked to see an engineer using a Yankee Screwdriver.
The battery never fails
I too have changed an iPhone battery, I agree, "don't try it"
Apple won't like you after what you just did..... 🤑🤑
Always better to put a new battery in an Iphone than putting a new Iphone in the garbage... Also if you need to choose, put a new battery, NOT the latest update towards obsolescence...
Rotary tables are soooo much fun to use in manual machining..... 😋😎👍
That's not a bad looking double ended yankee socket set. Using one of those is almost as shameful as using an Iphone.
I love this video it was so very instructive. But the title of this video is far too long. Here's a much shorter alternative title " Holy Holy Holy".
lol
I have been watching your videos for some time and find them very informative. I really hate to be negative but today's video was a bid disappointing. First you said something like "I have drilled them off center and l might explain it later and I might not". You didn't. Second you said that you really did not have access to the center of your rotary table for reasons you really don't want to talk about. Of course we have our own ideas why but if is not our business to know don't point that out to us.
You seem to be telling those watching your video that we are not intelligent enough to understand or that we are not important enough for you to take the time to explain it to us. It almost seems as though we are being trolled similar to "click bait" by teasing us when ever you essentially say, there is additional stuff to know but I am not telling you. Even if it was the result of an error or accident we would like to know to possibly not experience it for ourselves.
I know you have explained that you delete comment that are rude and you may delete this one, but at least if you do it means you read it. I like your videos and will continue to watch them, and really believe it would be a good thing for you to trust your viewers enough to include us in the "rest of the story."
the first 2 holes were off center to make room for 3 mounting holes
@@neiljensen9585 I understand that though I would have thought he might have used one of the two holes for one of the three since had to opportunity to transfer the holes prior to drilling the two holes. Regardless of the thought process, I just thought it was strange to say I may explain it or I may not when you are essentially making an instructional video?
I think you may be reading too much into it, I'm sure Mr. Pete just didn't want to spend time on items he felt weren't important for the discussion, not a reflection on the intelligence of his viewers.
As far as the center piece of the rotary table, watch the rebuild series on that table, I believe the answer is there IIRC.
