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!
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!
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! :-)
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.
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.
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.
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.
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.
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.
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.
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 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.
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?
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.
@@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.

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.
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.
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.
Novice here. What is the advantage of a dividing head if you have a rotary table with a set of plates? Particularly one of those fancy little rotary tables you can tilt. I know this is a very old video, so I don’t know if you will see it, but I appreciate it if you do!
@@mrpete222 Thank you for taking time to answer me sir! So, if you've got a tailstock for a rotary table turned on its side, is there any reason the dividing head is superior? Is it built with different bearing surfaces or something?
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.
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
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....
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.
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?
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!)
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 RUclips, 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
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?
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.
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.
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?
@@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😄
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.
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.
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.
I watch quite a few videos on RUclips 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.
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.
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..... 😋😎👍
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."
@@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.
Morning 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.

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.

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.
Another great video. I guess I'm so bass akwards I didn't notice you misspoke, but I understood what you meant. 😂😂😂
lol
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
Thanks for the video.I see it every day Here is a fan from Puerto Rico
👍👍
could have been nice to put the pins in, see if the errors were different than previous method.
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
Nice
It's been awhile since I seen somebody yes a Yankee drive
Yes, that’s why I used it
Good morning Lyle
Thanks for sharing sir..
Gesundheit! Und viel Glück! ;)
lol
hmmm, Arkansas speed wrench? We called the Oxygen-acetelyne apparatus “ Blue Wrench” it was “adjustable” also 👍😷
lol
Aka Gas Axe
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.
I watch quite a few videos on RUclips 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.

Lyle the Dumcaugh that crashed your rotery index table it can be tig welded with a tig cast repair welding rod 😁😎.
Nice to hear you speak German, it was not bad. 👍
lol
Good video. LOL on cell phone.
Yes
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.
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.
Rest in peace
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"
15:45 :-)
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.
