Nicely done, Michel. Working smarter, not harder. So you used a shaper to cut a keyway in a gear blank and then cut a 24 tooth "gear" on the mill so you could use it to make a 24 tooth gear on the shaper! If it works, it works. Brilliant.
Very clever on machining the height blocks en masse, love the ergonomic position of the dividing plate, no bending down. Making more, to make more (quoting yourself). Looking forward to some very clever machining Michel. Thanks for sharing.
Nice, you have a setup that works now, and a lot less of a pain to get in place! Bummer the gear tooth geometry was a hair off, but at least you now have proof of concept.
Good to see the mounting solution in action, and great work!! That will reduced the weight quite a bit which is better for your back. The dividing head will give you a lot more machining options for different projects in the future. I also like how you explain what you are doing in your videos. This is very informative.
The evolution of precision: using a sloppy part to make a more precise part. It's one of those things I love about (human) ingenuity. Especially in machining this is demonstrated so often and so effective.
Rudy Kouhapt was the man I admired when learning about dividing. Rig up a head stock dividing head for you lathe Rudy was an old tool maker who had series of articles in Projects in Metal. Many skilled machinists contributed to the Magazine articles. Rudy was the man. He passed away after my father in the nineties. All been done before. Want to divide? Get started now. Make clock gears and all kinds of stuff. I dont think I spelled Rudys last name right but he is missed and revered.
Michel, great work as always! May I make a suggestion? I would mark or number the feet and clamps so you have a consistent set up. It might not be required but could remove a variable that causes issues.
Hi Rusti that was very interesting to see and I look forward to involute gear cutting on the shaper. I have some gear blanks for my lathe and one day I will cut a 63 tooth gear on one of those. Cheers.
Hi Rusti, great work on the dividing head mod. Your calculations are spot on, there are a further set of formulae you can use to determine the number of holes, there are also many tables in books or on the internet that do all the hard work for you. More than happy to share my tables with you if you would like a copy as my head is also 40:1 (just makes the whole job easier). Cheers, Jon
Inspirational. You did indeed prove that it works. The modification you made has brought the dividing head back to life and will prove to be a very useful tool for you. Looking forward to seeing you make gears in the future. Now, where can I find myself a small dividing head. 🤔 As always, thank you Michel for sharing. 👏👏👍😀 Andrew
Super set up Rustinox. You could try lapping one of the feet to true the test bar, it should barley need rubbing. Great to see the dividing head being tried as well. Tony
Hey, Michel, glad that your setup worked out for you, it certainly looks sturdy and accurate. I had to make a gear for my lathe and my setup was a tiny rotary table (4") and instead of drilled plates I have a segmented dial. I used a boring bar type tool holder with a single point HSS tool hand ground to suit another gear. Anyhow, I enjoyed the video very much, take care and cheers! By the way, your mention actually made my day, thank you very much.
The problem solving seen on this episode reminds me why I love this channel so much. Great job Michel 👌 P.S. dividing heads are most commonly 40:1 reduction ratio but rotary tables are most often 90:1 ratio.
Hi Michel ☺ the setup worked great, as you pointed out the cutter needs some more work and then you can make gears for your lathe, or any other prodject. Thanks for another interesting video mate, stay safe my friend, best wishe's to you and your's, Stuart UK.
My Meat Grinder table,,,Love it :)> And howder1951 idea was super. Can't wait to see more uses you find using the Indexer. Have a super week end, stay warm, Bear. Sammie wouldd be sending you a Big Thumbs up for sure.
Hi Michel. Good one! Your calculation method is accurate but over complicated. Use the formula N over 40. Where N equals the number of divisions required, divided by 40. The number 40 or 90 as the case may be, represents the ratio of the dividing head. This formula gives you the number of turns required as a fraction rather than degrees. I was taught this method when I started my apprentice ship as a Fitter & Machinist. That was a very long time ago but to this day I still remember that formula. Take care Mate! Greetings from Australia. Paul
i thought this was really good because you got there in the end and a lot of people like me don't get as far as you did! 5 stars.( hope the neighbour does'nt need his wheel brace.)
you could have cut cut two flats on it with you mill , with out a fancy indexing head ,, old school work , all you had to do is cut the fist flat then used piece of square stock under to witness the next flat cut exactly parallel and opposite with the fist flat and the just use an adjustable wrench ....
Just a small observation. I noticed that you were climb milling when you were cutting the teeth. Would work better if you had the cutter on the front side of the part and do conventional milling. Depends on how much backlash you have in your table leadscrew and nut. You could of course also by a get cutter with the correct profile about 25 GBP on ebay. Great outcome. Regards from Australia.
Rusti Hi Great job, take care on working out the correct OD of the gear blank. In inch DP gears it is number of teeth plus 2 ÷ by the DP gives the gear blank OD I cannot find the formula for module but Google will. And for indexing giving number of turns on a hole circle of a indexing plate for your given number of spaces. Steve
@@Rustinox Yes, but the idea is that you only need a shallow dimple on the outside the part, not a crossing through-hole. Sometimes the part design can't take a hole crossing through the center, such as a drill chuck collar.
Well done great back saving device!! What does the dividing head now weigh? So once you get your tool rigid enough to cut the gear you can then fit it to your lathe to enable you to cut the thread you need to mount the chuck on your dividing head. I think I've got that right🤔🤔 I like the way you switch from one view to another and keep the narrative seamless. Great stuff!! Good luck from Spain!!
Great video. Perhaps it was just the video but it appears that you are climb cutting your gear teeth and I believe you would be better off conventional milling, i.e. feeding the work toward the cutting edge rather than away from it. Typically climb cuts are OK for a light finishing cut for for deeper cuts they tend to pull at the work causing chatter due to slack in the lead screws and tool deflection because the tool tries to climb on top of the work. Regrading your method of figuring out which dividing plate hole circle to use, the math works but it's a bit cumbersome. There are easier ways to obtain the same outcome using only the number of teeth desired and not using degrees. As always, great work, looking forward to your next production.
Sorry Michel the tablets aren't working today. Ignore what I said previously, the formula is 40 on N. As before N is the number of divisions required divided into 40 or 90, the ratio of the dividing head or rotary table. This will give the number of full turns and fractions of turns required. For example 24 teeth divided into 40 (ratio of your dividing head) equals 1.6666 turns of the dividing head handle. Once again I apologize for my senior moment. Paul :-)
Gday, brilliant job and a solid setup, thanks for sharing, cheers
Thanks Matty.
Great job building a dividing head. Keep on keeping on.
Thanks Harold.

It's indeed a very nice working height.
So much for not being comfortable with mathematics - you worked it all out using your own reasoning and it is a success!
Indeed. Thanks Russel.

Hello Michel,
The dividing head setup is very good and will be useful in allowing you to "Go for it" on many projects I am sure.
Take care.

It sure opens possibilities.

On line it's easy to find gear calculators that work really well.
Spanner hole(s) would upgrade the "tommy wrench" to fit some spanner wrench I expect you already have, such as for that precision drill chuck.
My old screw driver works fine for this :)
@@Rustinox Yes, but the idea is that you only need a shallow dimple on the outside the part, not a crossing through-hole. Sometimes the part design can't take a hole crossing through the center, such as a drill chuck collar.

Good Job Son Good Job

Did you say you welded the HSS blank to the steel? I have been curious about trying that for some time as well...
Go for it. It works very well.

No problem Paul. Thanks for your imput. This will be handy.
Since it is always 40 turns for a full rotation, just divide 40 turns by 24 (24 teeth) you get 1.666 no need to have 360 in any future calcs. 🙂
I suppose it shows I'm an absolute beginner with dividing heads.
Is apetor your brother?
Eh? Nope..
Your FP1 looks to be in about the same shape as mine.
Nice. This one is from 1964.
Good sleuthing! I'm sure you will have some further tinkering but looks quite workable. Enjoyed watching and discovering. Thanks !
Thanks John.
That's a cool tool. It will come in handy🔧⚒🔩
