Thank you for giving us a really nice video! There is a lot of information in it, very useful! I learned a lot from it! I also hope to provide more videos in the future! Thanks!
thank you for the comment and thank you for taking time to comment. It is much appreciated. It’s cool to find out where other people are when they watch the video. Thank you for the information.
Good day Ray, just subscribed. Great channel and certainly of great value to me. Just servicing my EMCO Deviding Head. My Dad bought it 40 years ago. 3 plates with (a) 27 & 34 & 42 (b) 33 & 36 & 39 (c) 38 & 40 holes. Had no idea how to use the DH and need to cut a new gear for meat-mincer gearbox URGENTLY. Problem solved🤝🤝need to learn a lot yet, so I will be studying your channel. Thank you. 🙏🤝Regards from South Africa
@@tonych7392 thank you for your reply. The ratio of the Emco deviding head is 40:1 my apology for having taken so long in answering. Thank you. Regards from South Africa👍🤝
Thank you for your reply! I am currently making a small indexing head to add directly to the spindle of my EMCO-3 mini lathe and you have provided me with very important information. Thanks!
My grizzly 6 inch rotart must be an odd ball. 90:1. Thanks for the video, using your math turned out great. 20 plate, 7.5 turns for one part and 9 for the other.
Thank you for this great information. I was just wondering why not use the Brown and Sharp or Cincinnati 49 hole circle instead of Cincinnati 42 hole circle for the 7 divisions example, if the idea is going for the most holes.
great video I m amateur and i need build small lathe with gear but i dont have a mesures of drive gear and follower gear please if you have a pdf or make a video
To cut a 26 Spline or division Is your indexing head of 40 to 1 ratio if it is you can use a Cincinnati standard plate side one it has 39 holes The division would be one turn and 21 holes in a 39 hole plate Ray
If you don’t want to do the manual work or you forgot how to do it you can go on the Internet and type in indexing plate whole calculator In the browser bunch your information in And it will give you an answer You still need to double check it doing it the old-school way hopefully this helps
Hi i enjoy your video a lot Coract me if im wrong 7 theet gear you had if i choise 42 holes plate then 7 hole each time would give me a result 16:52 Why 5 turns and 30 holes on 46 hole plate also you mentioned you go with 42 holes arlier (iam confused)
Can you explain why in the real world you would use the smallest number of holes plate and for the exam they want you to nominate the largest. I think that I heard you say that the larger number of holes is more accurate. Just confirming that I heard right. Because it is counter intuitive.
In the real world it’s easier to count to a smaller And also easier to do the calculations with smaller numbers The reason why the larger number is more accurate is because it’s further away from the centre That’s the only reason why Hopefully this helped
if the truth wear to be told , when a small shop wants to index's it possible they will not have a CNC tool do the job on & will need to index manually , as was the Norm in the past . so we ether learn & use the skill or loos them . all together/ Me I'm for learning any skill . LES THOMPSON. England old school is good to know .
I am new to the channel so this may make sense if I had time to watch several prior videos but I can’t today. Why not just use the real dividing head, why make a plastic copy. To use the real thing use the real thing, same size, cheap and available? Visually you don’t see more than if you simply point at it.
first off thank you for taking the time to comment your feedback is appreciated my thinking on this midget seam a little back words on this but consider my goals and problems 1 I needed a training device that I could test students on outside of the shop 2 a standard indexing head is $1500 3 a standard indexing head is heavy 50 to 100 LBS 4 a standard indexing head has a bunch of extra parts 5 I can not test students on a standard indexing in class without modifications 6 this unit weighs about 5 to 10 LBS with tools attached 7 made from extra parts so no up front cost 8 ( negative ) very time consuming with educational material and 3D printing All of the videos on the shop and math channel are to help apprentices learn if other people see value that is a happy bonus Keep in mind I do try my best to provide an honest and safe representation of machine shop practices I hope that you will keep watching and commenting All the best Ray
I agree there are calculators online that can do the math for you. As a machinist, you need to be able to do these types of calculations There are websites and calculators for speeds and feeds, but you still need to be able to do them by hand all the formulas and understand the formulas Ray
Thanks for taking the time to explain in great detail, how a dividing head works and how to pick out the plate for your dividing head.
Glad it was helpful!

Hello! What is the transmission ratio of your EMCO dividing head? I'm researching and learning now and want to DIY a small dividing head. Thanks!

You are a talented and dedicated man. I love you.
thank you
Katropa very informative
My grizzly 6 inch rotart must be an odd ball. 90:1. Thanks for the video, using your math turned out great. 20 plate, 7.5 turns for one part and 9 for the other.
The idea of having a portable training device sounds really good
thank youi
Are the plates the same in the metric world ? Thanks for the video.
Thank you for this great information. I was just wondering why not use the Brown and Sharp or Cincinnati 49 hole circle instead of Cincinnati 42 hole circle for the 7 divisions example, if the idea is going for the most holes.
I found your video very helpful could you tell me where I could get the model you used please it will help me very much
Many thanks glenn
Can you send me an email? I’ll dig up what I have or can find of the files and I’ll send them to you.
New to your channel, and be back often. Have an Enco 10in rototy table, so just jumping into dividing plates learning cycle 😋👍
For cutting a 91 tooth gear what hole plate do I need...a 40 hole plate??? with that how many turns & hole spacing??
Merci
Thank you for taking the time to comment. It is much appreciated.
great video I m amateur and i need build small lathe with gear but i dont have a mesures of drive gear and follower gear please if you have a pdf or make a video
5:35 I think you mean 42 hole plate and not 46 hole plate. Very helpful, though.
Thank u very much
Thank you for commenting and thank you for taking the time to comment. It’s much appreciated.

4:50 --> 40/7 = 35/7 + 5/7 = 5 + 5/7 = 5 + (5*6)/(7*6) = 5 + 30/42
What is the maximum number of holes in a standard plate?
its a cincinnati other plate hole
Hey there is a mistake at 5:37 you meant 5 turns and 30 holes in a 42 hole plate not a 46 hole plate!!
Fluition?
How do I cut 26 splines
To cut a 26 Spline or division
Is your indexing head of 40 to 1 ratio if it is you can use a Cincinnati standard plate side one it has 39 holes
The division would be one turn and 21 holes in a 39 hole plate
Ray
If you don’t want to do the manual work or you forgot how to do it you can go on the Internet and type in indexing plate whole calculator
In the browser bunch your information in
And it will give you an answer
You still need to double check it doing it the old-school way hopefully this helps
They are not selector arms, they are sector arms.
Hi i enjoy your video a lot
Coract me if im wrong
7 theet gear you had if i choise 42 holes plate then 7 hole each time would give me a result
16:52 Why 5 turns and 30 holes on 46 hole plate also you mentioned you go with 42 holes arlier (iam confused)

@@raygallant8631 Thank you it helps.
It is "sector arms" not "selector arms".
you are right the fingers that set the spaces are called sector arms
if the truth wear to be told , when a small shop wants to index's it possible they will not have a CNC tool do the job on & will need to index manually , as was the Norm in the past .

first off thank you for taking the time to comment your feedback is appreciated
my thinking on this midget seam a little back words on this but consider my goals and problems
1 I needed a training device that I could test students on outside of the shop
2 a standard indexing head is $1500
3 a standard indexing head is heavy 50 to 100 LBS
4 a standard indexing head has a bunch of extra parts
5 I can not test students on a standard indexing in class without modifications
6 this unit weighs about 5 to 10 LBS with tools attached
7 made from extra parts so no up front cost
8 ( negative ) very time consuming with educational material and 3D printing
All of the videos on the shop and math channel are to help apprentices learn if other people see value that is a happy bonus
Keep in mind I do try my best to provide an honest and safe representation of machine shop practices
I hope that you will keep watching and commenting
All the best Ray
i want to cut 79 teeth can you please calculate it for me
Watched it all, tried to purchase a 42 hole plate, does not exist I am told, WTF???
Hi Gordon
Sourcing some of the old equipment can be a challenge
Depending on the divisions you could always use the BS plate #2 21 holes
Ray
O
there are calculators online that do all this pointless math for you saving load of time
I agree there are calculators online that can do the math for you.
As a machinist, you need to be able to do these types of calculations
There are websites and calculators for speeds and feeds, but you still need to be able to do them by hand all the formulas and understand the formulas
