Watch pivot repair by percussion welding
zhlédnutí 879Před 2 měsíci
Percussion welding new pivot wire to repair a broken centre wheel in a pocket watch. This is still a prototype tool and the alignment not perfect. As such the welded wire is considerably oversized to allow for concentric machining of the finished pivot.
Miniature Percussion Welder
zhlédnutí 2,2KPřed 2 měsíci
Percussion welding has been around for over a century, but even today is not well known. Welding is achieved from an arc created by a short electrical discharge between the welded parts, while the part are rapidly approaching each other. The discharge happens a millisecond or less before the parts come in contact. The arc melts the tips of the approaching parts, so when thy come together they f...

Quick tool changer CNC mill
zhlédnutí 507Před 3 lety
The project started by combining two items sittings for years in the storage of my shop: An EMCO (Austrian make) milling head with column and a crude import X-Y table. One challenge was to convert the X-Y to a precision tool, and the other to create a very accurate sliding fit (no clamping) on the round milling head column.

Beautiful work! Thank you for sharing.
Bro I am doing a project on this and I cant find names of all the parts in the model you created , could you please provide me the names of all the parts in model you have created ? It would be really helpful if you could do that !
Beautiful little steam engine
Your machining is awesome! Lovely work
AAwesome
Never heard of percussion welding. Very cool
Cool project. You may want to lower your top end on the audio though, it's a little harsh. My wife thought it was raining from the background highs
Very good 👍
Watched both videos. Well done! Did you do a build log, CAD, etc? Would you be willing to share if you did? Thank you and excellent work and good inspiration.
not something I would do to a watchmakers lathe, but very very cool !! best regards Steve
The lathe remains fully functional.
Very encouraging results! Thank you for sharing this.
That is soo cool
Awesome
Fascinating design, and beautifully made. Being completely unfamiliar with the design, I apologise for what might be a very simplistic question, and perhaps a gross misunderstanding - but am I right in saying there’s a feedback loop stabilised by the resonant frequency of the fork, and the vibrations of the fork are coupled to the spring arms that hold the jewels, and the jewels impulse the ‘flywheel’ ?
You are correct, though I would not use the term "stabilized" . The fork oscillates at its natural resonant frequency and the generated sine signal (induced in the coil by the small change of the magnetic field) is amplified and the pulses used to actuate the driving electromagnet that maintains the natural oscillation. The vibratory movement of the fork tip is driving the large wheel vial a jewelled pawl.
@@billzweig Thank you for taking the time to explain. The clock is a beautiful piece of work.
What is this process good for? Dissimilar metals?
I second this question
The only parts I've ever seen it used for were watch parts, and the piece shown in the video looks quite small. My guess is this process is good for small/fine work where other processes would affect too large an area.
Dissimilar metals can be joined via this method. The process is being tested here for repivoting watch arbours as an alternative to the more traditional approach where the arbour is drilled, oversized stock fitted and then turned down to size.
This is one of the welding processes and in somehow different form - the so called nib initiated discharge - is commonly used for large stud welding. One advantage especially in smaller sizes is joining different metals, for example metals with vastly different melting points. In may version here it is to join small diameter parts while maintaining good concentricity and especially re-pivoting small pivots as found in watches, clocks and other small mechanical devices.
Nice work sir
Wow! Amazing and elegant, nice!
What ever happend to this design? Was it ever built?
I did not complete the full design, though I did more testing using the prototype shown.
@@billzweig that was unbelievable energy created with that design , I bet that could really evolve .
Hello sir can u please give us the patent number?
Application number 63187938, May 13, 2021.
@billzweig sir I checked this number but their is no patent registered can u please confirm the application number originally posted in your website sir
@billzweig sir I checked all patent websites but no information was available on the number given ,can u please re share.
@@sandeeps7979 This was the application number. I did not peruse the patent so likely considered abandoned.
@billzweig dear sir ,i am also building the same prototype it was cool when u had your website, is their any way I can get the patent file sir.
That's looks scary. Just buy a Harig air grinder.
Maybe not for the pusillanimous. but I never had any issue in the almost 20 years of use.😊
Damn that's nice! 👍👍👍
Making a Simple Rotary Broach Tool. Step 1: buy $80,000.00 worth of machine tooling and set it all up in a shop in your $750,000.00 home.
Great design and very useful build , particularly like the ER collett adaptor idea . Had my Alexander SO many years ,still learning its many capabilities
Very NICE. Gives me as amateur a lot of inspiration. Thank you for sharing Luc Bleckmann Netherlands
Thank you very much indeed for sharing your project. I am still very much an amateur and haven't begun to delve into what I can do with my clone of this machine, but this is a tantalizing peek at what could be.
Hey! I am working on a similar system. I have a question for you. What do you think would happen if the crucible was used as the flask, allowing the metal to be melted at the top of the mold and pulled immediately down into the mold while still under induction? This would eliminate the need for a valve system like yours (even though it is beautiful). I am just unsure if it will work the way I said it, or if it will be too hot on the mold or something.
It might work, though I think there will be some uncertainty with this operation. As well you need the metal to be fully melted and reach the pouring temperature that is bet slightly above the melting point. The graphite plug is really quite simple and a good place to house the thermocuple. Good luck with you project.
Very nice. I was starting to consider making something similar and you gave me some good ideas. Are your plans available somewhere?
solid model is on Grabcad grabcad.com/library/deckel-so-flute-grinder-1 . Good luck.
Very nice!

Hi the website is not working is their any link
Gorgeous!
Amazing!
You can't even show the machining? Geez...
Hello, are you able to share the design files for your project? Thanks!
Please load the part 3
Sorry, finally making it.
Do you have part 3 ?
Still working on it. Will have it soon.
Great 🎉 woow
Nice work. We shared this video on our homemade tools forum this week 😎
Excellent! We shared this video on our homemade tools forum this week 😎
Tightening up on that parrell strap contraption. It just like putting your gauge blocks in a vice. I'll bet they don't ring anymore.
Thanks for sharing I learned a lot!
Nice job. We shared this video (and part 1) on our homemade tools forum this week 😎
Man you have a great collection of tools! What's the max capacity of the broacher?
When will be part 3?
Sorry, finally making it.
That's great! Maybe I'm not understanding, so I'll ask. Once you touch off, wouldn't you specify the height of the device, not zero for z? Or are you accounting for that in some other way?
In the toll offset settings the height (17.28mm in this case) of the probe is already set. Really is is just depends how you set up your mill.
Thanks for this Bill, it will save me work calculating proper angles. I'm making one but using smaller bearings. One thing, on your dimension sheet you show a dimension of 41.6mm. I'm not sure where the two points of this dimension are. It looks like this dimension is not needed but I wanted to check with you in case I'm wrong. Also, what's the optimal tip protrusion? Thanks for your time and help.
The 41.6 is the initial bore diameter machined concentric with the outside during the turning of the body. It can be smaller as the actual size is not important - it is just to make the final, 47mm angled bore easier to bore. The tool protrusion is adjusted so the tip will cross the axis of rotation at that point - the tip is just wobbling without ascribing a circle. So the amount of protrusion is determined by the rest of the geometry; the angle and the offset from the centre.
@@billzweig Thanks for the reply Bill, I appreciate it. I have all the parts to make mine now.
VERY NICE
Good project Papa
