I've been running a mill and a lathe for about 40 years and can do setups in my sleep (not really), but explaining what and how to do it like Mr. Rucker can is an art unto itself. I know I couldn't do it, kudos to a good teacher!

Great threading sequence. Most just show the cut when newcomers really need to see the coordinated lever action. Nice job.

@july8xx 2 жыл бұрын

When making a non-standard thread I always make the nut first. It is a lot easier to test the fit using the nut than trying to test the internal thread using the shaft. Also using standard thread with an easily obtainable nut would make it easier for later repairs if necessary. But I must add this was a fantastic tutorial on thread cutting.

@ruidh 2 жыл бұрын

In his last video, Keith said he didn't have the correct stock for the nut.

@ellieprice363 2 жыл бұрын

I agree. He should have made the nut first, especially since it’s non standard left hand to be fitted to the long heavy shaft. It will be interesting to see how he does that. I’m guessing he’ll need to machine a short shaft with L.H. threads to use as a thread gage.

@clayz1 2 жыл бұрын

@@ellieprice363 Yes, a short thread gage for the nut. Now you can make a spec nut. But the shaft will be in spec too because it gets measured directly. So no need for the nut except for the satisfaction of screwing it on. Unless you want a nut that has minimum clearance (like a thou or two instead of .003/.007 probably, just guessing). A tight custom fit is nice.

Thanks Keith for the left hand threading lesson, excellent job as always. I really enjoyed all the different camera angles, that really helps in understanding all the steps and what you’re actually doing with your hands during those steps. This video would be a great primer for anyone who wants to learn cutting threads, either left hand or right hand threads. Thanks for leaving in the part where your halfnut doesn’t engage perfectly, I was just wondering what you’d do if it didn’t engage right. So thanks for leaving that in. Wishing you and yours and everyone else a Happy New Years!

Great lesson in threading Keith, when this is project is completed and time goes by (40-50 years) and were not around to warn the next person that takes this machine apart,...would it be appropriate to stamp LH on the end of the shaft?

Left handed nuts usually have a groove cut in them do indicate that, just look at your oxy set, fuel gas is left handed. I have seen mechanics tricked by left handed threads on wheel nuts on left side of trucks.

@@jhueth3969 If all nuts were undone by engineers, not such a problem. If turning a nut doesn't loosen it but tightens it, it's a sure sign of a left hand thread. You just need a sensitive enough feel to detect that.

Pitch dia. for 1 1/4-10 2a fit is 1.184max to1.177min rounded up which i do to be safe in tolerance. Since you are making the nut and it is not standard going to the other shaft and getting your measurement works too. Have to agree with others that the nut should have come first. To each their own and it will workout either way.

Much the best tutorial on thread-cutting I've seen yet. The thread dial was the missing link for me personally - no-one seems to cover this. Simple and obvious when you know how, but baffling for a beginner to hear people refer to a 'dial' and a 'number' without ever putting it in context or showing you what they're talking about. I now feel confident enough to actually try it myself - thank you!

Keith, I think that I agree with several other commenters about marking the end of this thread as "LH" or similar. However, I _really_ wish that you had modified that cutoff tool to have had (honed) radii to avoid leaving stress risers in the new shaft for future owners to deal with. I'm certain that such a tool would come in handy in future jobs in your shop!

Great video. It brought me back to the mid 1980’s when I used to have an old 21” Monarch. The most stressful work that I did on that lathe was doing 3-1/2 inch internal Acme thread at 4 threads per inch. You really have to watch carefully then disengage the screw, and move the carriage forward a couple of turns simultaneously. All very nerve racking at the speed needed to get good results in aluminum. I don’t miss that much but enjoy seeing you working and explaining to us how and why you are doing it. Thanks.

@johnjohn-ed9qt 2 жыл бұрын

Quite a nice introduction. The debate about 30deg, 29.6deg, or straight in goes on and on. The best argument I have heard for 29.5 over 30 is that it insures both thread flanks are smooth in a world with inevitable errors in the tool angle, compound angle, tool setup, and so on. A few minutes here and there should be less than the 0.5 degree. The internal stop for threading is so nice. I miss my old lathe that had it (Pacemaker), so I made a drawscrew type for my current lathe (better than the clamp type that grabs the cross slide ways, in my opinion)

@mrsock3380 2 жыл бұрын

It doesn't go on in the machine shops I have worked in, never seen anyone angle the compound to cut a thread besides on KZfaq, at trade school the teacher told us about it but never did it. You can work out the ratio to move the compound to keep it cutting on one side or after a few hundred threads you just wing it like every machinist I know does. The reasons I don't angle the compound is that you can't just work out the depth and go straight to it, for large threads you can't clean up both sides and if you're using the compound for widths or lengths you would have to move the compound every job. For a hobbyist it isn't even something to argue about, the end result is the only thing that matters, not efficiency, so whatever works for you.
