[@dizzolve]

now that we have decade(s) of Mr Pete videos ....... this is quite the vast library of information that you can just about bet your bottom dollar Tubalcain has covered the topic. Like this one. Thank you Lile

[@Abom79]

I enjoyed the video Me Pete. About the thread triangles, I have two sets that were my grandads. I know for fact one set still has the chart in them because I use them occasionally. They are handy when you don't have a nut, or want to copy a part and cut the thread to a matching size. I'll have to show them in a video. Thanks for sharing. Adam

[@mrpete222]

Take a look at Bill lewis's comment above. I printed the chart, and it seems to match up with my triangles.

[@normanfeinberg9968]

Very good .This old dog is learning many new tricks because of the internet and folks such as yourself.Many thanks

[@cat637d]

Another good one! I always wondered how the thread wires were used and now I know! Thanks Mr. Pete, You are a National Treasure!!!!!

[@MrUbiquitousTech]

+cat637d He sure is!

[@GuzziIan]

Thanks again Lyle -your videos are truly an education.

[@MrUbiquitousTech]

LOL, "darn gravity"! I can relate to that! Thanks for the lesson Mr. Pete, that's great info there! I like your method of holding the gauge wires there!

[@isbcornbinder]

You have a nice comforting voice. This video was most informing, for me.

[@mrpete222]

+Bob Smith Thank you very much

[@MrC10H15N]

thanks Bill Lewis for that handy chart and great video Mr Pete tubal Cain and Abom your awesome too love the videos keep up the good work

[@mrpete222]

+MrC10H15N Thank you very much

[@Tranartz]

The nice thing about your videos is that I can't break anything while I'm learning!

[@ianbertenshaw4350]

I have been watching that sore on your left hand evolve and am waiting for it to grow an eye ! Excellent video as always and i had never seen thread triangles so i learnt something new!

[@timothydaniel4511]

Your depth of knowledge is impressive, thank you for sharing.

[@rbrianlindahl5499]

That plastic thing to hold the wires would have saved my arse in my machining classes last quarter... pure genius. note that the machinery's handbook has an acceptable range for the diameters, thus the range of values you were seeing for the commercial thread vs. yours. thanks for the video!

[@RTBerserker]

Thank you for taking the time to explain this in such amazing detail. I appreciate this video very much. I’m verifying threads in a position I’m currently in using the 3 wire method and this has helped me understand so much it’s greatly appreciated.

[@mrpete222]

👍👍👍

[@JunkMikesWorld]

Mr. Pete, Good video! I had never seen the triangles before. I simply show my students to use a nut to test the thread. After all I only want to peek their interest with the hopes that they will continue on to an apprenticeship or a trade school to broaden their knowledge. Thanks! All The Best! Mike

[@mrpete222]

Yes--In the HS shop we used the nut method 99% of the time.

[@bestfriendhank1424]

Pretty cool Thanks for taking the time to make this video

[@johnw.peterson4311]

Nice job Pete.

[@kentuckycowboy2]

Thank you mrpete for another very interesting and informative video.

[@newbrook700]

I really appreciate your video. Now I learned how the wires are used. Thanks!

[@harlech2]

I just bought a set of Scherr-Tumico branded thread wires made by by Pee-Dee. I founf it kind of curious that Scherr-Tumico, even back in the day was farming out some of the odds-n-ends, even the the simple stuff.

[@mrpete222]

Thanks, that is interesting. I only realized fairly recently that Brown & Sharpe did the same thing. And probably many other companies as well to fill out their product line.

[@xull1x123]

If you don't mind the small cleanup, I use grease to hold the thread wires in place. Thank you for the video

[@larryphillips5490]

I also most often use the nut method, but on occasion have needed to use thread wires. I never had a problem figuring out how to measure with them, but lordy have mercy, I sure could have used the tip on the delrin holder more than once. Lol Thanks for the great videos Mr. Pete.

[@mrpete222]

+Larry Phillips Thank you very much

[@robertdiaz2563]

greeting , tubalcain iv been working as a machinist now for about 40 yrsand for the passed 35 or so yrs in the movie industry . earlier this week I was asked to cut some threads for a ceiling fan extention (about 8 ft. extention ) I did not have a theard gauge, so I used the pee dee thread method worked great .thanks for your show very informative bob diaz

[@johnhili8664]

Mr Pete thank you for the information its good to learn that these measuring devices existed.I have 50 years experience as a machinist but with all due respect I think those measuring tools are for space shuttle technology not for the man in the street!!

[@mrpete222]

+John Hili Thank you very much

[@Patroand]

Like the 3 pins holder Thanks

[@pierresgarage2687]

Hi mpete, Reminds me my first times when the bloody wires kept falling in a chip pan with about 10" thick of chips, took soooo much time to sort out the chips and the wires... Bad memories.... Internal measures are another story though. Thanks for sharing, Pierre

[@jayjo448]

Great video, I'd never heard of thread triangles before. Genius way of holding the wires, too! I've never had a problem doing it without assistance, but it seems I'm a rarity in that. Grease is popular with others I work with. Elastic bands tended to cause magical flying wires One correction though, pitch isn't the line in the middle of the major and minor. It's the imaginary line where on the thread, if you were to look at it from the side as VVV, the spot where the width of material still there, is equal to the width of material missing beside it. Hopefully that's simple enough for everyone to understand. Wikipedia has a harder to understand explanation, but same idea. In practical use, not a big difference from what you said. Also, just because I've seen a lot of people confuse minor/major on interior and exterior threads, it's been easier to explain it as major is always the big one, minor is always the smaller. Calling the minor the root of the thread on exterior, seems to have people assume it's the root of the thread on the interior threads as well, which it isn't

[@mrpete222]

Thanks for the tip.& correction

[@arkansas1313]

Thanks for the teaching, I learned a great lesson! ....13

[@larryschweitzer4904]

Old video but I had just looked at an old video of Joe Pie's where he makes a good case for using just one wire. Given that I have an excessive # of thumbs I like the one wire method better than 3 wires.

[@MrEh5]

I like the three wire method as you can check if you thread angle is off also.

[@mrpete222]

+Bob Cartwright Thank you very much

[@morrisgallo2361]

Great vid. Instead of drilling a plastic rod you can use a plug of beeswax or silicone putty, simply roll the diameter plug needed for the screw size.

[@mrpete222]

+Morris Gallo Thank you very much

[@robertfenney]

Thanks, I learned something new today!

[@johnhollyfield6557]

I will repeat a comment I read below. National Treasure! this info is invaluable! thank you. My old Shop teacher from University Md (John Strenge) taught at Matoon HS, Illinois, in about 1950, before he moved to Md. jh

[@mrpete222]

THANK YOU VERY MUCH. Did not know him---a little before my time.

[@EitriBrokkr]

Thanks Mr.Pete

[@BigMjolnir]

Thank you for the demonstrations and information. I'll be trying my first single point threading soon, and won't have a nut I can test with, so this is timely. Since I've gotten interested in machining I've started noticing how things are made, or might be made. Looking at your go/no-go gauges I'm a bit stumped. The turning to size and drilling of the holes to allow movement for adjustment is easy enough, and a slitting saw to cut the adjustment slot to the outside is obvious, as are the counter bores for the adjusting screws. Where I get stumped is on the relief slots to the various adjustment relief holes. A slitting saw won't fit inside the center hole, the slots are wide for a bandsaw, and narrow for a milling cutter that could go that deep without breaking...so how were they made? A laser or water jet could do it, but I understand that such gauges were in use long before such machines were available. How would you make those? Perhaps when you run out of "what is it" ideas, you could do a "how was this made" series. -- Mike

[@experiencingtechnicaldiffi5184]

+BigMjolnir How about a broach or a die filer with a screw slotting file or even a keyseater. Google them. Often a machine built just for that one purpose. Mike (o\!/o)

[@jimkoonce6574]

Very informative, thank you.

[@MAX-vn1sy]

Good Job ! very detailed

[@mrpete222]

Thanks!

[@mrayco]

Triangle method is awesome

[@jenniferwhite6089]

learn some new with this video thanks never know what the tread wires were used for now i know

[@tomauth3419]

Nice video very informative thanks for sharing

[@MrShobar]

When I worked as a machinist in a production facility (many moons ago), we never used PD wires. Only preset ring and plug gages.

[@NSTRAPPERHUNTER]

Nice video and thanks for sharing.

[@SlowEarl1]

Great video thanks for sharing.

[@mrpete222]

+SlowEarl1 Thank you very much

[@johnnytakisawa]

I use one wire. Know exactly what your maj diameter is and take your measurement over the wire. Subtract maj diameter of work from your wire measurement. Multiply by 2 and add back to your maj diameter. Little bit of math but easier to hold.

[@h37s3m]

What happened to your left hand? Fascinating and great video, thanks!

[@jeffmoss26]

Very informative as always!

[@mrpete222]

+Jeff Moss Thank you very much

[@EE-mg7vn]

I use 2 of the same parts that has threads and stand them up, placing 1 wire on one side and 2 wires on the other side. I can pick them both up between the wires very easy and measure the pitch diameter sliding the micrometer over the part that need to be checked.

[@MrShobar]

A gum rubber eraser also works to hold PD wires.

[@specialks1953]

Maybe some fine fan will have a chart for your "Triangles" method. - - If you get the chart, it would be very easy to use rubber bands to hold the triangles in place on the threads you are measuring.

[@Opinionator52]

Certainly when a tight tolerances are needed just using a nut won't do. Your videos always offer excellent explanations on proper procedure with the, when/and how to accomplish the required task at hand... Thank you for your expertise, Tubalcain! :o] O,,,

[@mrpete222]

Thanks for watching

[@GK1918]

I do have wire mics etc. but being old school I still like to sneak up on it..

[@jameshollister7855]

very well explained. thank you.

[@AmateurRedneckWorkshop]

I think I would rather have the micrometer, lazy old man that I am. Thanks for sharing another very informative video with us.

[@mrpete222]

+cerberus Thank you very much

[@danndao1783]

thank you very much!

[@TheDefeatest]

So what is the high end of tolerance of the pitch diameter on these sets? If you are 5 thousandths over is that good? Or do you just go from on size to minus?

[@hisexcellencytrump855]

Wine bottle cork works good too to hold wire method

[@jackyboy50]

great video thanks

[@1DIYGuy]

Your delrun made me think how about styrofoam. Last time when using the 3 wire method I used thick axle grease which worked but would not recommend for reasons you could guess.

[@1OlBull]

Nice information, Thanks...

[@mart209lo]

“Darn gravity” Nice lol

[@kennethandree1849]

Mr. Peterson, I thought you would enjoy this video on Colchester lathes

[@ketchumdan9095]

You can't bad mouth the safety nazis with a wound like that. My curiosity is piqued. Love your vids. Thanks

[@mrpete222]

+KetchumDan Thank you very much

[@altonwhipkey2411]

Used a lot in the screw machine shop

[@ConradoLusa]

10:44 how did you come up with this pitch diameter?! The chart tells us nothing about this ?

[@MrShobar]

The USS thread standard is the ASME's National Engineering Landmark no. 234.

[@mikeadrover5173]

As always, thanks’ for taking the time to make this video! And I support this site. ~M~

[@MegaSalvatore13]

Thanks

[@tzkelley]

Seems like you could recreate the triangle chart by measuring with one of your other methods. If you were so inclined.

[@mrpete222]

+tzkelley Thank you very much

[@normanfeinberg9968]

P,S.,I've found "Silly Putty"will work nicely with the three wire method

[@morrisgallo2361]

KBC lists the thread triangles, come with elastic bands and chart. You supply mic. Less then $30.

[@mrpete222]

+Morris Gallo Thank you very much

[@reinforcedoctocopters2993]

could you please put al these vids on a dvd set, I would buy it

[@mrpete222]

I do not have them on dvd. I DO have tips #1 thru #110 on flash drive for sale. . See my recent video title senior discount ATLAS & SOUTH BEND LATHE Video Courses tubalcain for the offer.

[@dogbuggy32]

I like it

[@robincox8902]

I like the way you hold them wire, I put grease on them. Slippery little sucker. Rob

[@mrpete222]

+Robin Cox Thank you very much

[@billshiff2060]

It should be noted that thread wires were never intended for measuring production threads. They were intended for measuring precision ground thread Gages which have near perfect thread form. Proper thread wires need to be and are as accurate as gauge blocks and cost $3000 a set from Van Keuren. Using cheapo wires in a shop situation should be thought of as a rude and crude bandaid estimate and not an accurate measurement. They can easily show a defective thread as good especially as the pitch helix angle increases, the errors grow larger. Thread micrometers are better but still not perfect. Ring gages are the best of the simple methods but still not perfect. I've had cases where the wires showed the thread as good but the parts all had to be scrapped.

[@MrRbt61]

i recently picked up a starrett no 6 thread pitch gage it shows pitch plus ? ex, 13 threads .133 what is ,133 i can not find on minor dia for 13 thread it measures .133 deep not double depth

[@pietzeekoe]

Can't you just measure the altitude of the thread triangles to figure out how much to subtract?

[@timothysiders6624]

Shouldn't you be using Gage lube??

[@tonygombas491]

Is that an eye 👁 on your left hand

[@softuniverse7771]

any way to measure female threads?

[@giatiencktran9455]

tôi muốn mua một bộ ,bạn có thể gửi sang cho tôi được không

[@aubreyaub]

Mate, I have a 1 1/8" thread, @ 9tpi. Where/how do I find Pitch/Effective Diameter for this. I have 'Machinerys Handbook 2005', buggered if I can find it...? Trying to make Go/No Go gauge, and die for an antique engine. Bolts are stretched, ie, necked...you know what happens to 'em. Reckon, best way will be to make 12 new 1 1/8" diameter 12" bolts, but my friend who is the Engine man, says that if we can just resize 'em, she'll be jake.. I can see what he means, and I do not want to move any more metal from these studs, than is necessary, as you can imagine. Thanks for your videos, learnt a lot, here 'n there. Still learning, 70 next month. edit. There are a lot of threads out there that are, for arguments sake strange. F'rinstance lets just speculate a 10" bolt or pipe or whatever, that may have a thread pitch of 1 to 50 tpi, . or even .05 to 10mm pitch. How do we find the PD/Effective diameter, in these cases.? Reckon it will get down to pure mathematics, not my favourite subject, and if this is so, then just say so, but any help or hints about where to go to assist, mate, greatly appreciated. Cheers, Mark Needham Qld Australia.

[@tomherd4179]

Did you see Joe Pieczynski's video; kzbin.info/www/bejne/mJaZgmyjopmpe7M where he uses 3, 2 or 1 wire to make a measurement? Do you know of a formula for the Pitch Diameter? I have yet to find one and when I try to make one from various thread pictures and factors I come close but not right on the mark.

[@juliusvalentinas]

Micrometer for every bolt? No thank you. 3-Wire Thread Measuring Set 18 pairs, for D= 6,35mm Spindle Item number: 313-101 Suggested retail price: 2,174.00 €* No thank you. I'll just buy good quality bolt, and wire and make my own table what micrometer should show me with certain diameter. Screw the overpriced wires.

[@robfrancis8830]

Kinda screwy subject

[@derick3482]

13:40 it's whatever you want it to be
