Small tip to keep you sane. There are rubber holders available so you only have to manipulate one wire, or put a dab of grease where you want the wire pair to stay. And as someone mentioned already, a cloth under everything will keep you from having to search for the wires you swore you wouldn't drop again.
You bring me back to my high school machine shop class, my teacher was one of the biggest influence in my upbringing, he was hard on us but he taught us so many skills that seem lost now, I left school and went into machining but unfortunately I burnt out on running a CNC, it makes me smile to see you running manual machines and showing people how to use their brain
I'm in my 20s and use thread wires very often. Although I do prefer the thread micrometer. But it's not realistic to have a 3-4 thread mic that you only use every now and again.
@@colehoulden9127 When I was in my 20s I never even considered buying thread mics just too much money, but one of the shops had a 1" & it spoiled me, so now I have them too, but only to 6" (bought the last 2 just after I made this video)
I had to cut some really coarse threads once, the pitch wasn’t covered by my thread wire set, and I didn’t have a matching nut. So I used some small diameter drill rod to make my own. There’s a formula for that, and it worked great.
Even if it's a different angle, a little trig gets you there. you choose the pin diameter to hit the middle of the thread. I use this for acme, or special threads too.
Great technique I learned from Joe pie measuring with one wire so you don’t need 5 hands. Measure over the threads with one wire , subtract the radius of the part, and then multiply that number by two. I just actually use that today at the shop on a 3.75” left-handed acme thread ..works great.
Great videos, I started not long ago to do some machinery in the place i work but i always find your vídeos very useful for tips and some insightfull thoghts about machines and how to aprouch towards some workpieces and thinkikg about how to do or how to think about it. This vídeo about thread Aires i dont even know how to use but is good to know thats a option and i’ll see if i can learn more about it and how to use it. The only thing is that here in Brazil 80% of the measure is in milimeter and inches is not very often for us, but the lessions are good for both. Thank you very much for the videos
Used to use thread wires all the time but I now don’t ever make or modify big parts at the company I’m at. Ended up getting a thread mic. The prices of getting the anvils sucked but it a pain using those with small parts
I remember from my machine designer days putting all the over the pin dimensions for spur gears on my drawings. No computers or cad syetems at that time.
Yes, and very handy method for making a gear to match an unknown sample (if part of the original teeth still exist), if the "over pin" number matches it will work.
Was just using wire yesterday to measure an m16 x 1.5 thread i was cutting. I actually prefer wire, so long as it isnt too large a diameter. Lay a rag over the ways to catch them if you drop them!
wires are inexpensive, I tape 2-1 so they are at least easier to find when dropped. But also thread mics are expensive, and the anvils wear out, rather quickly... and cause all sorts of headaches, wires are accurate, and consistent.
There is only a small amount of information here. Very general in the description. Put for accuracy the basic effective diameter is what your measuring. A better video could be produced but time in a machine shop is something that controlled the issue.
The main issue is UA-cam shorts, they get promoted more than regular videos, but must be under 60 seconds. The "thread pitch" is the spacing between the threads, and the "thread pitch diameter" is the diameter of the threads, measured from the theoretical middle of each thread.
Normally called the Effective Thread dia... the thread V blocks are put together then guage thickness measured and subtracted from the overall measured piece..
I had a set of mitutoyo 1-5 mics inherited from my father. Depth mic and some digital calipers. Im not a machinest so they had to go to a better home. Kinda regret the calipers as I am a expert lvl handy man and they would have come in handy but analog is what im working with. 😂
Umm, I thought the thread pitch is either the distance between thread roots (or peaks) or the number threads per linear distance, both along the length of the thread, not the diameter of the thread... Am I wrong?

I use Transmission Assembly Goo...its tackier than grease and works Great!!!
I have used the rubber holders & did not like them. My first choice is thread mics.
I hear you brother
I tape 2 of them with scotch tape
@@danielbailey6619 that works too.
The drop cloth is the actual pro tip of the day. We all learn it after going chip-diving at least once in our career. 😂

Howie, you rock! Young kids today have never even seen thread wires let alone know how to use them. We are a dying breed my friend.
Sorry bud but I know a ton of shops that use them still. Aerospace even. Sometimes old tec is the right tool for the jerb.

Joe has some unique and amazing tips, deserves more UA-cam fame than he gets, should have subs in the millions
Some people get taught one way like this guy and they never think about doing it any other way. The way you just explained it was obviously easier. 🙌
@@Phantom-mk4kp agreed! Awesome teacher
Only works if the flat is good on the opposing side.
THE BEST Way to cut threads!
If an old timer says “maysurement” shut up and listen
This gives-can you feel the grove-vibes!😂
I always use a little grease to help keep the wires stuck in the threads.
All my homies hate the three-wire method until they lose their calibrated thread standards for their various thread mic anvils. 🗣️🗣️🗣️

Manual machining will always be a love of my life lol
Usefull tip thank you always Nice to watch those vids
Yes and to save money on tools at one shop I worked at if it was an inside thread we had to make a gauge this way to check the inside thread.
Many times it is not the cost, but the time waiting for an official inside gauge.
Great information. 👍🏻
That adds up !!

Use chuck grease it stays in place and doesn’t mess up your reading
Good looking threads.

I've done that. I had to. It was my job.😊

Use a little grease to make it sticky so it's stays in the thread
Awesome 😊

Silly puddy is your friend when using wire .
I put the two wires on the bottom, find the O.D. then back off the mics til I can get over the absolute top of the 3rd wire.

I bet you still own the mitutoyo thread mics anyway…
PD wires are great but my thread mics are king
Why can’t you use a thread gauge?
Thread gauges are for a quick check of pitch, if it is a common one. Thread mics would be the other option for checking the diameter.
I used a rubber band
Umm, I thought the thread pitch is either the distance between thread roots (or peaks) or the number threads per linear distance, both along the length of the thread, not the diameter of the thread... Am I wrong?
You are correct IMO bad terminology I think. This measurement is depth of cut, especially if you don't have local master nut for testing the fit
The three-wire method measures the pitch diameter between the crest and root.
The "thread pitch" is the spacing between the threads, and the "thread pitch diameter" is the diameter of the threads, measured from the middle of each thread.
thanks fer the sound ! i was wrong take thr sound out again lol jk
Drill bits are even cheaper. A little math to interpolate.
I'd rather have a sock that won't sag ❤
Or I could just guess.
If you buy Mitoyo Starette will go out of business.
That horrible camera work. Be Better.
A lost skill.
Terrible camera man. Would have like to see the other side of that whole situation
That's not accurate
