Your methods at times scare me as far as safety goes and your fingers as holding things with your hands can lead to the loss of fingers and I have seen eyes put out in machine shops I have worked in but still I have never seen so much made with so little.

"We the willing, lead by the unknowing, are doing the impossible for the ungrateful. We have done so much for so long with so little that we are now qualified to anything with nothing at all"! You personify that statement! You Rock my friend and I say Kudos to you. What a beautiful job you did with rudimentary tools. Your ingenuity is to be admired. It takes a person with knowledge of such devices (worm and worm wheel) to appreciate what you have done. The unknowing will just look at it and see nothing.

You can make a good guess at a tooth radius that will work by doing some math. If you are off by a small bit, the setup will mostly self correct, dividing the error evenly spreading the error across all teeth. You run into the same challenge when knurling - a knurling roller has a set spacing that you want to work out to wrapping around the part an integer number of times. But nobody uses a divider to lay out knurls.

@pauls57453 жыл бұрын
I guess if it's brass, you could just keep running it and increase depth until clean teeth were evenly formed, but youd have to be pretty close to the target OD to start off. Im sure there's charts for # of teeth for diameter based on TPI, but it might be faster to do the math than search for that. (1 /your bolt TPI) = spline spacing, then multiply that by # of splines you want = Circumference, then (C / 3.14) will give you the OD inches. there's other ways. this will get you close

Hi ! The idea is good but...... The tool you used to create the teeth on the crown would have to be slightly different. As there is a height difference between the tooth head and the tooth foot, the tool would have to be modified so that the coupling between the screw and the crown was more precise. It may work, but it can't be too demanding on the system.

I mean, you could take it around once, and it could obviously just start a new threading overlaid on the old one, messing up the point -- the thread had to **exactly** match into itself after one (and each subsequent) revolution of the work gear blank.... even a fraction of an inch of variance would have meant a less than accurate in-fit with each successive revolution, meaning slop... How did you determine what was done/needed?

Could be wrong but I'd think after hand turning it to pilot the threads then having the lathe spin it several hundred times most likely created the path needed based on the positioning (how true/little the tap had any play) it creates a true pattern automatically based on it being a circle, plus possibly he just did the math based on thread space/circumference of the circle idk lol :P I'm lonely what can I say.

Every step is very clever and practical, you are a great machinist. But there is a design flow. The surface of a bolt's thread is quite raw, it's not the best, the tolerance neither and its not hardened, not designed for continuous rotation and friction. A real worm gear is relatively cheap, and its, much more pedantic part for this task. It's not worth replacing it with a bolt in my opinion.

This is either problematic or self- solving, and I'm not smart enough to understand which. So the threads can never be off by more than 1, this helps. Also, when the threads start cutting, they must be off in order to be correct when finished cutting, owing to the tpi getting tighter as the tap bites deeper. So, if not aligned, just keep cutting deeper until it is perfect?

A lot of work with many steps shown ....all good. BUT .....not knowing what the "purpose" or "application" is, there are several questions. Where is the "adjustment" for wear? Someone commented about "good engagement" with worm gear sets. Actually ...quite the opposite. There MIGHT be engagement in only on how deep the thread is generated. 180° is the maximum, which is really a lot, and only ONE thread pitch is engaged. So if this is purely "reduction" your needing, and there is no significant load, this will work for a while. I couldn't help notice the chatter at 1:32. You are not going to get a very good surface finish OR accurate thread form. Just wondering why the spindle speed was so fast ....also no cutting lube? And lastly, the bolt you used clearly showed it had a very poor finish on the thread. There were several points where we could see the thread. One was at 7:05 and you can see numerous "nicks" on this thread. I suppose this "project" was to demonstrate steps of machining and fabricating. To anyone thinking this is for "high torque" applications, it is not ....not with this kind of standard thread. An acme thread would be the first choice. .

Most everything was well done. However, there is no way to adjust the backlash of the worm gear and worm wheel. It is very obvious that there is significant slope between them. This is detrimental to many applications. Being able to adjust that backlash is crucial to many applications of this technique. Also, it would be good to be able to predetermine what the exact ratio would be and how to determine the outside diameter of the two gears. Also required is the depth of the worm wheel recess. This is fine for crude things like lifting mechanisms and such but, not for when precision is reequired. Regardless, the video itself and the overall construction was well done.
