That initial plastic setup was so good. I was wondering how they would index gears by using a worm type cutter and that setup was just it. Loved the vid to the end. This explained all. Thnx very much.
An exceptionally well done explanation for indexing. thank you very much. I picked up your method for eliminating backlash from the mechanism when indexing. that is dropping the pin onto the surface plate just before the hole and then tapping it into the hole in the direction of turn. Simple but very effective, I shall use it in future. possibly you can explain to your viewers the importance of eliminating backlash and that the handle must not overshoot the hole. Importantly that the pin must be dropped into the hole only in the direction of rotation.

"move the sector arm". If you say that one more time I'm never going to forget it... Oh, I think that's the point. Very clear and concise, I learned a lot in watching this.
It frustrates me that I spent a decent amount of money taking a night class for machining to learn beyond the basics and was required to do just that. I specifically requested training on such things as rotary tables and dividing heads but apparently that was to advanced for that class. I should have saved my money and just stuck with UA-cam. Watching your 11 minute video took the mystery out of dividing heads. Tech schools must hate guys like you taking their business. Keep making the videos and I'll keep watching. Thanks.
thank you very much sir. This video cleared my concept of plain indexing and well a day before my exams i was able to understand what it really is, thanks a lot appreciate your great work!!
thank you for making such a fantastic video. it really helped me understand the concept. it would be really great for me if you could please upload a video on Compound and Differential indexing.
yash kalsi This is something I have thought about for a while...I'm trying to get my head wrapped around what the video would look like as it is a fairly complex setup. Thanks for the reminder Yash!
Thank you so much this was nice and clear. I always wanted to know how the indexing worked. The only part I didn't get was the second sector arm. There were two sector arms and I was wondering how did you know how to space the secondary sector arm to the right amount of spaces? Maybe I missed it but you placed the first sector arm against the pin and the second sector arm in an equal space but I'm not sure you mentioned how you did that. Anyways thank you so much. Now I need to try this hands on so it can stay in my memory.
The sector arm moved is always the one that will touch the pin, if you move the other arm the arm that hits the pin may cause the one your moving to shift. They are set by loosening screws at their base then tightened in the new position. I too learn better when I can try a task. I think most trades people are tactile learners.
Hi Chris as we speak I'm trying to get my head wrapped around what the video for differential indexing with a compound gear train would look like...there is a bit of math involved. Thank you for the suggestion. Keep watching!
Thanks a lot first of all....Its just awesome..I could really understand how is the indexing formula used and mainly why do we use 40/N as many of the lecturers were not able to explain...Thanks again...
nice video. I have a Myford dividing head that runs at 60:1. Being a computer nerd I set up a spreadsheet to do all the calculations for me. I just type in the number of indexes i want and it lists the disk plate No, Number of holes ring, then the number of full turns and the number of ring holes to turn. Saves a lot of this horrible maths stuff. Also set up so that if there isn't a correct ring disk it will tell you how many ring holes you need so you can make your own disk. Had an idea last night if you wanted to cut two flats with an angle between them, working on that calculation to add to the spreadsheet. steve
Sir,can u upload subtitle,Actualy i cant recognize what u tell in between 3-5 minute,this video is realy helping me,but i want more clear about this topic want clear about 35 holes on 49 holes divisions
I have the loan of a Myford dividing head. Put a card disc on the faceplate and a sharpie in the chuck, set the pin in the hole circle to match up with the chart to give me say thirty divisions. But I'd never spotted that you don't count the first hole. So if I did all the dots on the card, when it got the starting again, the dot was not over the same spot. I just could not work out what was going wrong. Counted of the holes again and check the chart, but still whatever division I chose the same result until I spotted your almost casual remark, " Don't count the first hole" Eureka
@@machiningmoments I have a 36:1 ratio rotary table. I need to drill 7 holes in 360* , I know 51.4*. Do I use a 49 hole division plate ? What is your suggestion ? Thanks.
Any plans on making of video of how to drill your own plates? Might be a tougher one to make, but the knowledge sure would be great to have. Thanks again for your work.
Hello again, these plates are done in a CNC but this process is straight forward. Choose your drill (we use a center drill) decide what diameter you want to use (less holes closer to middle, more holes closer to od). set your indexing 40/N (N = number of hole on the diameter your working on. If you had 21 holes it would calculate to 40/21 or 1 rotation and 19 spaces on a 21 hole plate. Drill, repeat 21 times. I hope that helps?
I realize you get what you pay for. I notice China import versions of indexing units with tail stock attachment for mill as little as $400 or so. Then $1000,$2000 + with no end. Have you seen or used the imports? For hobby work do have reasonable accuracy for a hobby shop or simply junk and waste of money? Any brands of indexing units you might suggest? Thanks
Hi Adrian, there are some good products that come out of China. The problem is most things come out of China these days. I think as a hobbyist you likely don't need to spend big bucks. I'm a fan of the comment section/Google search for comments on items I'm looking to buy...take advantage of other peoples experiences.
machiningmoments thank you for your reply. RH course on a lathe would be great! (even fine if you had the time too but no biggy). Im struggling to understand the correct measurements you turn down the outside diameter for an external thread mostly. Thank you muchly! :)
Jon Gene Hi again Jon, I am assuming you are working with a Unified thread (very common in the US thread system). All threads come with an identification code (callout) such as 3/4-10UNC-2A. This gives the machinist the information to create the thread. The information that controls the outside diameter (and pitch diameter) in the unified thread is the second last character in this case the "2". This callout will be referenced in the machinery handbook new.industrialpress.com/machineryhandbook under the unified thread section for 3/4" look in the table for a class "2" fit. there will be a max and min outside diameter (and other information). Example (and I'm guessing as I don't have a handbook with me) the class 2 fit maybe as large as 0.748" or as small as 0.735". Any diameter in the referenced range will be acceptable. Thanks for the question, I hope this helps. I struggle with this medium sometimes, if I was beside you and had a handbook it would take 30 seconds to explain this.
I was expecting at least a.... "First center, then offset to 0 mark. Divide 360 by x holes and that is your degrees. This is how to setup the dividing head.". But instead got "watch me drill a hole guys."
Hi. I have a 37,39,41,43,47,49 hole plate. And I want to cut a round workpiece into a hexagon. 40/6 = 6 &4/6, which means 24 (6x4) spaces and 36 hole plate. So how do I do it? Waiting for your kind reply. Regards
You can't, with that holeplate. Do you have a slotted plate behind the chuck, spindle? If so and assuming it has 24 slots you can use that plate to index (if 24 ever 4 slots).
It seems you made a mistake resetting the sector arms before the first cut. You should either have moved them back to where they were, or forward as you did, but lifted the pin so it would have come to rest on the other side of the arm. In the end it id work out though.
That initial plastic setup was so good. I was wondering how they would index gears by using a worm type cutter and that setup was just it. Loved the vid to the end. This explained all. Thnx very much.

Should be able to do that for you. Thanks for the comment.
machiningmoments thank you for your reply. RH course on a lathe would be great! (even fine if you had the time too but no biggy). Im struggling to understand the correct measurements you turn down the outside diameter for an external thread mostly. Thank you muchly! :)
Jon Gene Hi again Jon, I am assuming you are working with a Unified thread (very common in the US thread system). All threads come with an identification code (callout) such as 3/4-10UNC-2A. This gives the machinist the information to create the thread. The information that controls the outside diameter (and pitch diameter) in the unified thread is the second last character in this case the "2".

Thanks for the question, I hope this helps. I struggle with this medium sometimes, if I was beside you and had a handbook it would take 30 seconds to explain this.
wow you are a great teacher 👏👏.But what if I require 23 divisions?
40/N so you would need a 23 plate or 46 plate or the ability to reduce the fraction to a suitable plate.
Well explained 👍👍
Thank you.
Video is realy helping me,but i want more clear about this topic. my question is how do you desired diameter of the job please give me replay.
The diameter is set by moving the cutting tool up or down from the center of the part.
I was expecting at least a.... "First center, then offset to 0 mark. Divide 360 by x holes and that is your degrees. This is how to setup the dividing head.". But instead got "watch me drill a hole guys."
explanation ; just like Marilyn Monroe..gorgeous!

Hi.
I have a 37,39,41,43,47,49 hole plate. And I want to cut a round workpiece into a hexagon.
40/6 = 6 &4/6, which means 24 (6x4) spaces and 36 hole plate.
So how do I do it? Waiting for your kind reply.
Regards
You can't, with that holeplate. Do you have a slotted plate behind the chuck, spindle? If so and assuming it has 24 slots you can use that plate to index (if 24 ever 4 slots).
Thank you for your reply. No I don't have a slotted plate either. I guess i will have to buy a new hole plate.
Yes, you are limited. That is a problem when there are multiple plates, the ones not in use tend to get lost. Good luck!
40/6= 6+4/6 = 6+26/39 (you can use the 39 hole plate)
It seems you made a mistake resetting the sector arms before the first cut. You should either have moved them back to where they were, or forward as you did, but lifted the pin so it would have come to rest on the other side of the arm. In the end it id work out though.
clears everything...
