using this method you are machining the gear with varying pitch diameter because you are using the cross feed. What I did was to machine the od of the blank with a groove matching the id of the tap and a circumference which is a multiple of the pitch of the tap, Then bring it in with cross feed onto the end of the taper of the tap. Then use the saddle to feed the gear onto the tap. The cut is done always at the same diameter on the wheel.

@Ol' Camo Somemthing that I have figured out over the yers is that there are many different kinds of machinist. You have folks that make one off parts, they tend to have tight tolerances and can take more time to achieve prefection and people that are what I call production machinists who focus more on speed and just stay between the linse as perfection only adds cost. I find that someting these two groups but heads a bit. There is also a line between manual and CNC machinists or even mill and lathe machinists, they to can be a bit tribal. Point is that if your making parts for a living your a machinist hell you could only use a file to make em and still call yourself a machinist the only real question is are you a good one and even that could be subjective.

When working for my uncles in their small shop we used to manufacture small worm gears for a company that used 1/2-13 threaded rod to make their worms. We cut the gears on a Barber-Coleman #3 gear hobbing machine using a 1/2-13 tap. Obviously you need to calculate the proper diameter of the gear blank but using only the downfeed of the machine it produced beautiful throated worm gears by the hundreds. Nice video.

@@李孝民 We converted the 1/2-13 UNC threaded rod to the comparable diametral pitch which is 40.83 DP. Using standard worm gear calculations for the 100 tooth gear (number of teeth/diametral pitch) give a value of 2.449 inches for the pitch diameter. The worm gear in this case was throated so standards call for the throat diameter to be the pitch diameter + (2 X addendum). As this was a non-critical application we chose to treat the addendum as one half of the whole depth of the thread (in this case .0472 inches) and add that to the pitch diameter. The outside diameter of the worm gear is pitch diameter + (3 X addendum) so the finished bronze gear blank ended up being 2.520 inches. OD = PD + (3 X addendum) Hope this was not too confusing.

Would it not be more important to have the exact diameter at finish to match the even numbers of teeth per inch at the end when the tap is 50% of its diameter (i.e. it’s radius) cut into the circumference of the wheel? If it’s say 20 tpi tap - then your diameter needs to be 22/7 x (X) - radius of the tap -= say 40 teeth. So you need X value to end up 2 inches long circumference to get 40 teeth / 20 tpi = 2 inches circumference. Then you know the inside circumference must = 2 inches & the starting outside diameter must be 22/7 x diameter and allow the extra 1/2 of tap diameter ie tap radius? That should give starting diameter to end up with 40 teeth on 2 inch long circumference? Man that made my brain hurt. I shoulda paid more attention in math at school. There was moths flew out my ears, I disturbed their resting place in my brain after those neuron brain synapses haven’t been used for 45+ years. I could be wrong - that was just a mental arithmetic attempt, I didn’t check it with a calculator or anything, so don’t take my word for it.

Это не реально, чтобы в круговую нарезать зуб, потому что при углублении нарезки меняется длина окружности, следовательно шаг нарезки меняется и не будет совпадать начало с концом окружности. В итоге никакой резьбы не будет, она будет срезаться после каждого оборота на шаг несовпадения. Чтобы действительно таким путем нарезать зуб, то нужно расчитать диаметр и количество зубьев укладывающихся на расчетный диаметр. И нарезать нужно за один проход на всю глубину нарезки, а не так как показано по чуть - чуть. Одним словом монтаж сьемки.

+fragwits Totally different situation. When tapping, the pitch diameter is the fixed and the tap advances in a line at a rate of one tooth per revolution. In this application the gear blank rotates at one tooth per revolution of the tap at the circumference, but the circumference (and therefore the number of teeth per revolution) changes as the cut gets deeper so it will take fewer cuts/teeth to make one revolution of the blank.

Well done, although brass needs no lubricant and using such can, and did, cause the chips to stick to both the tap and the work piece causing issues. I saw you were using a brush to deal with the chips sticking to the brass gear; that's not necessary if you don't use lubricant. Also the tap, as with any tools used on brass, needs to be brand new and sharp, i.e. never used on steel. This advice comes from a Trade Qualified Fitter and Turner (Mechanical Engineer). Great job, great vid :).

I don't see how this works, indeed it looks like the tooth profile is marginalized as the radius of the cut decreases. I think you have to cut them in a single pass at the intended radius for proper teeth otherwise it is like crossthreading from hell. Just set up a jig like you have but feed the tap in, instead of feeding the piece in. You can contour the piece a bit first but don't go too deep or the threads will again be marginalized.

Blank diameter is figured as follows: (thread pitch) x teeth number desired divided by Pi (3.1416). Example if you used a 1/2 x 13 tap and wanted a 72 tooth gear. Ex: .0769" Thread Pitch x 72 teeth = 5.5368 divided by Pi = 1.762"

Please could someone explain to me the reason why on this gear - and on items that are machine knurled - there appears to be no "double hit" or overlapping of the thread? It intrigues me and has done for decades. Surely at some point a diameter must exist where there is a mismatch in pattern ratio?

Completamente de acuerdo, el bronce en sus distintos porcentajes de aleación permite ser mecanizado sin añadir lubricante debido a la estructura que forman, los metales y los no metales, permitiendo que el arranque de viruta requiera poco esfuerzo por parte de la herramienta . Por otro lado la fundición, posee intersticiones de grafito, que es un lubricante natural

and still i am always wondering how the start and the end of the gear groves will come to a magic overlap - especially because the diameter of the work piece will start to shrink during machining. (same wondering when it comes to grid pattern engraving on a late using a set of rolling engraver wheels put with some pressure onto the work piece...)

You are right. It seems like magic. I think the diameter has a lot to do with it. The diameter would have to be divisible to the thread pitch; I think or something like that Joe Pieczynski has an alright video on knurling. It deals with timing of knurls, and the diameter affecting the final outcome. I know its not the same just some food for thought.

The OD of the part has to be figured out by the number of teeth on the tap. Number of teeth divided into the circumference. You play around with the diameter and teeth until it is even, no over lapping.

How can it be , that once the workpiece has made its first rotation, the cuts perfectly line up? And not destroy the previous cuts by overlap? Or is this circle perfectly measured out to match this specific thread cutter? (non machinist here, just watching for entertainment).

I used to grind gears at caterpillar, and on a larger scale, its hobbing, just on a much smaller scale. If you were to start at the leading edge of the work piece, and run all the way down to the bottom edge, it would actually be a decent hobby grade straight cut gear, run multiples at different diameters and you could, theoretically, build an entire gearbox.

How do you ensure the gear meshes when the worm has turned 360, or did you just keep pushing it into the tap until they do? In which case each movement of the transverse will cut on a new circumference and the new cuts will be out of sync with the previous.

That has got to make weak gear teeth. The pitch changes with each movement of the wheel. I'd think it would be better to shape it with a drill bit, then cut the teeth in 1 pass. Ps. Aren't worn gears normally cut with acme thread profiles?
