YES!!!!!

Thanks. ...good video....my name is ajay I am in Indian. ..

I agree a lot with the "Brush off" instead of air, i cant remember why but i was told it can be dangerous too by my tech teacher in high school.

The risks are air embolism with air lines also chips being blown into eyes or other places where you don't want them to be they can destroy DRO scales

Interesting how many professionals have not seen this done. Iv'e never touched a lathe and iv'e now seen it done multiple times. How else would one do this? Or is it just lack of interest of this specific product that makes you guys not see how this is done?

how to fix the gear diameters For the screw of pitch?

@@user-ec3ij6mt3p 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.

Hi. Did you (or somebody) tried the same with trapezoid tap? When I found this video, I realized this could be the way to make my own thread chasing dial gear.

Hogy jön ki az osztás milyen kerületen jönnek ki a fogak?

@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.

@@derangedspyder I'm a "one off, tight tolerance, CNC Lathe machinist". We tend to get along with everyone, lol

That's what I was going to ask. If its a 1mm pitch tap the circumference of disc should not be decimal point. Should this be at the start of machining or what?

Such as?

Buenos en 43 años que llevo veo esto muy bien pero seria para el puro bronce porque dañar esa macho como llamamos aqui en venezuela en hierro no vale la pena pero me gusto la demostracion muy buena se haria en bronce y en aluminio jajajajaja

@@sinisterhipp0 I came looking for the answer here to so the round has to be the correct size , or you will have to watch until the threads come together .

Yep ditto that, add me to that list.

Should be using paraffin or similar when cutting aluminium. WD40 works pretty well.

I was thinking of the same problem, that solves it, thanks !

Que es, para que sirve lo qie hizo,alguien sabe.

I am thinking the od and the pitch just would have to be divisible into a whole number

I’d probably end up with 63-1/2 teeth🤣

@@poopcow32 I'd think circumference at worm center divided by screw pitch would need to be a whole number.

Very simple calculation based on OD, number of teeth and pitch of the teeth/thread. ODxDP-2=Z or PD+2 Addendum.

Were you making a new worm + wheel system or doing a repair for a current system ? And can you always use a tap or do they make specialist cutting tools for this ?

@Dustin Eward Knurling seems to be really hard on bits. But yeah, somehow it magically sorts itself out and looks good even after bad math, lol.

Can you please suggest a video of this method? Thanks.

This is the better way to do it and more akin to how commercial gears are made

I assume that he must have had to assemble it.

We all have tools we bought on impulse or it was the only place open when you really really needed a tool

Damn, I saw that and I thought I must have been mistaken.

So?!! It's a tool that gets the job done. That's all that matters.

A bolt for a worm means much more side thrust on the worm.

Константин, раньше. Я такой способ видел в какой-то технической книге 70-72 года выпуска. Там же и приводились формулы для расчета наружного диаметра нарезаемой втулки в зависимости от шага резьбы. Они несложные и понятные. К сожалению это некая эрзац червячная передача. Подобие.)))) Для несильно нагруженых механизмом пойдет.

Any diameter will be fine as you will just grind it until everything fits, if you chose wrong diameter you will just need more time. also he is not moving everything up down so he got worm gear.

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"

Best Racing Tips Win At The Dragstrip Now we have blank diameter rightly calculated. Thanks.

registered. thanks.

mauritor mayb not so critical as the cut deepens..

Igotknobblies The method demonstrated is called free bobbing. The workpiece is forced to rotate by the helix angle on the flank of the cutter. Works fine for light power transmission, probably not consistent enough for accurate positioning.

webtoedman yes, I quite understand the theory behind free hobbing, like I said, it's pure luck if the first and last tooth of the revolution of the workpiece are a perfect tooth distance apart, and like I said, if they're out by 50%, you could end up chopping all the teeth off.

Igotknobblies Unless he calculated the diameter exactly.

PaintHerWhite but wich diameter the initial or the final? I think he calculated the initial, because the center of the gear seems a little flat than the borders.

Igotknobblies Except it’s a well known and understood process. You are the one without a clue here.

JACOB HARMON its not about tools..

Generally I would agree, but I can't/won't pass up the chance to rib a fellow machinist for using his wife's adjustable wrench on a KZfaq video. Name on the tool doesn't matter if it does what you need. Maybe the good natured joke got lost in translation....
