Old video but the information still holds true to this day. Had a buddy reach out with an issue of stripped threads and I sent him this video.

This system is considered to be superior to other thread repair systems.

What size do you need to drill out the hole to get a 5/16 bolt in a Healy coil

greattt 🎉

That is one cool tool. Makes me want to go do a rebuild just so I can use it.

Very breve explaination and very easy to understand thanks brother to take your time to educate me MAY GOD BLESS YOU AND YOUR FAMILY AND YOUR WORK AMEN AND AMEN HALLELUJAH 🙏🙏🙏❤️❤️👍

Excellent presentation. Back in the day, as a welder, I was often tasked with weld repairs to both impellors and pump housings. Bronze and cast iron impellors and cast iron housings were typical. Both of those metals present substantial problems to almost any (electric) fusion weld process. Much of the metal to be resurfaced was lost to cavitation, most to erosion from sand and other materials in the water. I was never able to grasp how gas bubbles could remove metal nearly as effectively as sand and other contaminants could. My professor in Metallurgy 601, Dr. Ralf O'Brien (Northern Kentucky University 1986) never could get this through to me, though he was a great teacher. This presentation makes it more clear simply by giving the numbers: 60,000 psi, is a lot of pressure! Thank you for this program.

Excellent presentation. Thank you!

Oh something new only 11 years old thanks.

정말 훌륭한 설명입니다,논리적으로 이해 못한것을 쉽게 설명해 주셔서 매우 감사합니다 ^^

Very good, thanks

That was one of the most educational and clearly laid out explanations I think I have ever seen in my life thank you!!

Outstanding explanation of cavitation. Detailed and easy to understand and apply to every piece of equipment subject to cavitation damage. Thank you!

Here's a simplified way of explaining Cavitation in pumps ruclips.net/video/j61CzVtPEbg/видео.html

Glen canyon dam had lots of problems with cavitation trying to quickly lower the water levels a few years ago

This video is so helpful ive been installing helicoils without fully understanding whats going on and now i do and its glorious. thanks! also to other comments saying they are just for repairs, thats not totally true they are also useful if you have a soft metal part like aluminum but need to be able to screw bolts in and out repeatedly, since just aluminum threads will get messed up from that

WOW‼️®™️ 💯💯

I liked your instruction.

I have used Cross Wire Inserts (Helicoils) for many years, and they are much cheaper than this type of thread repair bush insert. Also if the stripped hole is close to the material edge, the Cross Wire Insert (the old original Cross Ltd) will work well, but the thicker bush insert may be too close to the material edge.

Note that this video is pretty old. I noticed that the kits now come with a Red Loctite to use on the insert, probably for more strength...

Dude u are fucking dope, visual learner with great narration, A+ man

Congrats nice video, what's the name of the tool used to remove a Time Sert Insert ?

Thank you. You just added a new tool in my toolbox😀

C'est une excellente leçon Traitant de la cavitation : depuis la Tunisie je vous dis Merci infiniment !!!

Excellent, thanks for posting!

Great, step by step is much appreciated!

Excellent video, thanks. It is good to visualize the process

I love this tutorial, VERY straight to the point

. Are all helicoil inserts the same across all manufacturers meaning would the thread cut to take an M8 helicoil for example be suitable for any other make of insert?

Great Vid - many thanks.

do these come in a left-hand thread? Thanks for the video.

Hi There.... Would the insert be able to handle the torque specs??

My favorite part about this video is the octagonal chamfer, which adds to the realism

This was actually a really good tutorial, solid animations. Very informative.

Excellent, so condensed and informative. Thanks.

This is the basic theory of a helicoil kit, and a very good one. This video has real applications but I have found scenarios where some of this won't work. It could highlight the overall process a bit more, which is: (1)drill (2)tap (3)helicoil installation. In short, you drill to make a new, clean hole size. Tap to cut in new, larger threads. Install a new coil, which creates new threads. Now you have a new internal thread for your bolt. Made out of steel, which could be better than the original. Thanks for the video!!!

Awesome graphics , very descriptive and insightful! Thanks

But you're going to tap out the hole after you've drilled out the old threads, what's the point of the helicoil?

Beautifully explained!

Great video and explanation -- thanks!

Can you use two time serts if you have an 1/14 thread cavity?

This video was perfectly done.

my teacher showed this after our cavitation class in fluid mechanics discipline

ok

Ends abruptly...but good information.

Excellent.

ولا واحد من جماعة أستاذ علي خضير هنا 😂

Excellent explanation..Thank you

Wow. That's the best TimeSert tutorial I've ever seen. Thank you!
