Я тебе скажу больше, все негативные комментарии написаны глупыми людьми. Им нужен умный станок, поскольку своих мозгов нет. Пишут что такая шестерня имеет неправильную форму зубца. Хотя за форму зубца отвечает резец, который выточен автором именно так, как ему надо. Уверен что автор может при необходимости поставить резец любой формы.
Unfortunately the negative comments are well deserved. There was no attempt to grind a proper shaped gear cutter. A simple V shaped cutter is a waste of time. Even with basic tools, with only a moderate amount of effort it is possible to grind a better shape than the one used.
You will note that the cutter forming the tooth spaces is straight sided. Gears, worm wheels and similar forms generated from a straight toothed rack are involute curves. Amateurs approximate them with a calculated radius. This example will produce a very noisy running gear, suitable perhaps for low speed, and would damage any correctly formed gear that it mates with. Assuming it is the same size (diameter, pitch) as the gear used to index, it would have been better if the cutter had been ground to match the shape of its tooth space.

@@timrussell1559 Cool your jets bro. I've spent 40yrs as a Tool & Die maker, then Engineer in the Aerospace/Defence industry and hold several patents. My handle might be a clue. Photography/video, even discussing the particulars of my output is strictly forbidden.
Having run a gearcutting machine shop, I can tell you that there is much more involved in producing gears than this. What this chap is doing is improvising which is ingenious, but he will never produce gears that properly mesh and last a long time. There’s not many engineers that have done gearcutting, it tends to be a specialised field.
That's 100% true....Even sharpening a Hob must be done extremely precisely so the profile of the tooth will create the correct profile on the gear. This is really just a gear that "will work" however far from ideal and it's life will be much shorter. I'm a Tool & Die Maker but have also done Tool & Cutter grinding and Gear Cutting. Precision in Gear cutting is out of this world!
It's a well-known technique if you need to occasionally make gear but don't have access to the milling machine with proper divider attachment. My dad did this when I was a kid. He was using a proper involute cutter instead. With an improperly shaped cutter like in this video, the gear would be noisy and suitable only for low speed. It's not a big deal to make a proper cutter though.
@@ironmike742 It's a matter of sharpening the tool. It's 10mins work providing that you know you need it :) This guy does not know that the shape should be different than trapezoidal.
You know the good thing is we can make the indexing jig for our machine shop. Great idea to use the lathe as a horizontal mill, it's good to use machines that you already have, instead of buying a lot of extra equipment.
Not to mention that most gears could be used for a variety of indexing applications by dividing the teeth. For example, a 24-tooth gear could be used to index 24, 12, 8, 6, 4, 3, and 2 evenly spaced positions. Might be a good application of an old set of change gears for a junk lathe.
Sad see so many negative comments… This man is doing the best he can and doing a good job. Everyone can be a machinist in a workshop where all the tools and materials are…. Only a few real good machinist can do a good job with only a few tools available 😀.
This is a very intelligent comment about a man in a very destitute part of the world making do with the tools he has to solve mechanical problems without the CNC computer equipment that all of you engineers have in your A/C shops.
Everyone has come to understand and know the art of blacksmithing and turning. I swear that if you were put in a workshop like this, most of you would not make just a trivial nail.
First of all,I would like to appreciate this work that type of fixture has been made but there isn't any different thing.Many types of jigs and fixtures has been made like this before to remove metal. Well done!👍
Dear Sir Paul Brown, As an engineer I submit to you that the work this person is doing, if this work is viewed in the perspective of mechanical engineering, it is against all laws, rules and principles and the gear that is being developed is extremely wasteful and bogus.
No negative comments here. This is a very ingenious way to cut a gear, let's give the guy credit. There are many ways to get the job done, including: wire, water jet, vertical cnc, dividing head on a manual mill and so on.
It went on tight, my guess is that it was hammered loose off camera and the film resumed right when it was pulled off easily by hand. The bottom was not shown I am guessing to hide the hammer marks.
The articles that are published are more pakistani centric. You may get still better ideas in India as we have a larger industry base and machine tool manufacturing hubs.
And he determines the root diameter of the gear by eye? Close enough for light load, low speed application, but it will not hold up for very long. Too much play in the setup to produce any amount of accuracy.
I like how these video's promote "genius", and you never see a work bench and they always seem to be working on the floor. they make dandy gears and such, but can't build a work bench.
Well, at least we see a clean lathe. But why overtightening all bolts and do the allen setscrew with the standard allenkey? Besides the already mentioned shape of the cutter, what about the condition of the “master gear”?
Good job , but if you add a center point to the axle it will be easier ,faster and stronger to mill without vibrations , you can add it in the screw’s center and mount it on saddle
Lot of people are commenting on the shape of the cutter not being an involute instead straight.Well what can I say the guy most likely don't have a tool and cutter grinder and if he did he would most likely own a milling machine with a dividing head since that's unlikely he is making the most of what he has to get some one out of the shit to get their machine running.Whether he is a genius or not that's open to discussion.

Good work for a man with limited equipment. The idea is not at all new as similar methods were once standard. However, several points cause a tendency for inaccuracy. Not to mention gear sizes, pattern gear, etc. Great and not worth a damn at the same time.
how could u get the exact depth of the tooth..bec. u have no adjustment to get the tooth depth...and one more. ..how could u get the center of the w/p before u machine..
I assume this is a way to help out. No serious production, although the tools used do not look freshly improvised?! -better spend some time turning a proper cutter disc out of HSS and a proper arbor. And if you stick to this set-up: give the back end of the hole the cutter is held in a thread of a practical rate. Screw in an allen key screw. Make a dial with a center hole through which the allen key goes and use the handle of the allen key as the hand on the dial. (Give the dial two pairs of fingers on it’s back so it is always positioned over the arbor in the same way) After setting depth, clamp down cutter again. In this fashion you should be able to adjust cutter depth within a field of play of about 1/10 mm. Good luck with it!
For HIS area he did a good job. At least he used a measurement device to set the cross feed in the right angle. He did make a copy tool to make the teeth spacing the same. Compared to HIS collegues in HIS area who only measure by eye and guess he's almost a genius. The result is still a very basic, very noisy, fast wearing gear. This is probably the reason he's NOT making it out of steel. This new gear is softer than the original so it can wear itself in because the teeth shape isn't right.
