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.
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.
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
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
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.
Leave it as a fraction rather than converting to a decimal. The fraction is a ratio. 40/7 is an improper fraction which becomes 5 and 5/7. Then you find a multiple numerator and denominator to get a suitable holeplate.
A DIVISION PALTE HAS PROBABLY MANY MILLIONS OF YEARS OF EXISTANCE, BELIVE ME,,, it was inveted by a genius, nowadays you have masters and soime imbeciles with enginner diploma, and those , thye dont invent anything they ahve their brains preoformatted. by hit
Bob Krell Hi Bob, Cincinnati dividing head has a 62 division hole plate. The formula is 40/N so 40/31= 1 and 9/31 multiple the denominator by two to get the hole plate (62) you will also need to multiply numerator by same number (2). Your answer is 1 turn (revolution) and 18 spaces on a 62 hole plate. Never count the hole the crank pin was in! Good question, good luck!
40/28 = 1 and 3/7 You need a hole plate that is a multiple of 7 so 7, 14, 21,28... multiply the numerator and denominator by the same multiple. so if you use 28 it would be 1 turn and 12 spaces on a 28 holeplate.
+Alex Steel Hi Alex, the formula for simple indexing is 40/N. In your case 40/6 (hex) so 40/6 reduces to 6 and 2/3rds you now need to find a multiple of the denominator that will equal a hole plate you have and multiply the numerator and denominator by this number. Example if you have a 42 hole plate 3(denominator) times 14 = 42. Both numerator and denominator are multiplied by the same multiple. The answer in this example is 6 full turns and 28(2x14)spaces on a 42(3x14)holeplate. Good luck with your TQ!
Ok, answer with calculations. Can be done with direct indexing, two spaces on a 36 tooth direct indexing plate (worm gear disengaged). 36/18=2 spaces. It can also be done with simple indexing (worm gear engaged) 40/N in your case 40/18 which reduces to 20/9 or 2 and 2/9. Find a hole plate that is a multiple of the denominator 9. Whatever that multiple is multiply numerator and denominator by it. Example say you found a 27 hole plate...3x9=27 and 3x2=6 so using the hole plate in the example your indexing would be 2 6/27 or two full turns and six spaces on a twenty seven hole plate. I hope that makes sense!
40/N in your case 40/14 which is 2 and 12/14 or 2 and 6/7. Find a multiple of 7 for a hole plate you have. For argument sake let's say you have a 21 hole plate. Your multiple is 3. Your answer is 2 complete turns and 18 spaces on a 21 hole plate. I hope that makes sense.
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.
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."
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
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.
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.
sir paano poba pag lumampas sa ratio ng deviding head ang ngipon.. example 120 ang ratio ng deviding head ko tapos gagawa ako ng 135 na ngipin paano bayun .. sana po masagot
Kakailanganin mo ng isang malawak na saklaw ng paghati sa ulo o kalkulahin ang pagkakaiba-iba ng pag-index kung ang iyong naghahati na ulo ay hindi kaya ng paghahati na iyong iminungkahi.
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...

Hi Brad. In an earlier reply to a comment I made you indicated you would like to have another topic for your videos. I have an extra copy of Machinists Workshop Dec2007 / Jan2008 edition which details how to make a ring roller using Caterpillar engine Wrist Pins. I think it would be a good project for the students which they would have for future. I have an extra copy of the magazine I could mail to you if you wish - need the schools mailing address. I bought about a dozen copies of the magazine and have been giving them away to friends. Rod from Vancouver Island

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).
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.
Thank you very much sir, from this video I cleared my concept. This is the best explanation. Thank you once again.

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)

Hi! Love your vids on your channel..just wondering if you could possibly do one on internal and external screw cutting? Thank you :) Jon
Hi Jon, any particular thread in mind? RH, LH? Course, fine? On a lathe?
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". 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.
thanks a lot sir.please upload some video on gear shaping using pinion cutter
Thank you, I'm not sure I have the equipment.
Thankyou sir nice explanation
I'm glad it was helpful. Thank you for watching.
