How to do Engine Turning JEWELING Tips
HTML-код

- My friend Palmer Moynihan is my guest instructor today demonstrating engine turning. Sometimes called JEWELING. FROM WIKIPEDIA -----"Engine turning, also known as jeweling, is a fine geometric pattern that can be inscribed onto metal as a finish. Aluminium is often the metal chosen but any metal can be finely machined to produce intricate repetitive patterns that offer reflective interest and fine detail."
Do a google search for "Damaskeening".
I am 72, I watched my dad do this when I was 10 years old. That was 1958. He used valve grinding compound. First he turned a wood dowel. He did this process on heat treated steel by hand on the drill press. My dad was a master at this. He made an angle plate with tapped holes. It was beautiful. I used to come home from school and just stare at it in the sunlight. I retired seven years ago after being self employed for 31 years with my own cnc, fab and laser cutting shop. I have not seen a RUclips video yet that does it as precision freehand like my dad. Sorry guys.
John, if you use double sided strong tape and stick a leather disc on the wood dowel, with the rough leather as the cutting side, use the grinding paste and it will do a fair amount before it is worn, the grinding paste should do the real work, not the leather. You can also use super glue / cyanacrolite type glue to stick on discs which Acetone will remove the glue when you need to put on a new leather disc. I don't press the leather down too hard, allowing the grit to do the pattern!
I would have fought and fought trying to keep a consistent amount of compound on the tool, and never thought to just apply the compound to the material. Thanks for sharing the idea!
My father was stationed at a small arms repair factory in Germany during the occupation. He was an MP. He befriended the owner of the factory(really more of a small machine shop than a factory) and bought his Luger. It had been "fabricobbled" together and machined to have some smoother curves - and the trigger itself had been jeweled. I've still got that Luger - and the receipt that came with it! It sure was some small little circles. I figured they had used some kind of dental tool or something to do it - with one of those pastes you showed. It was nice to see you guys having fun in the shop.
I guess I never realized you could do that process on something that small. I like those lugers
mrpete222 Its also a common process on watch movements. Antique American watches have some very elaborate patterns. Look at the Illinois Bunn Special.
@@mrpete222 Have a look at high-end mechanical watch movements. They call this 'perlage'.
Sometimes just doing the opposite of what you think is 'right' works beautifully. Thanks for a terrifically simple technique.
I think I laughed even harder the second time seeing Palmer. Sure was fun meeting Palmer and Wayne, great guys.
We sure did have fun together that weekend
My uncle Neil made a knife for my grandpap when he joined the Navy in WW2. Neil jeweled the blade.
The knife has plenty of patina, but still shows it's jeweling.
That is awesome
Probably the most notable example of jewelling is on the engine cowling on the Spirit of St. Louis.
Yes thanks
Holy shit, man you ain't joking. That nose is gorgeous.
That was the first thing that came to mind.
Absolutely the first thing in my mind too. I’ll bet fella would be mighty proud to know we were talking about the quality of his work nearly a hundred years later.
In the 1957 Billy Wilder film with Jimmy Stewart they showed them using a wire brush on a drill press. I don't know how historically accurate that was.
Very nice, thanks to both Mr. Pete and Mr. Palmer for sharing this! Looks great! I'm going to try that one out.
I miss the original 3 in 1 oil cans, the plastic garbage today with the worthless uncontrollable plastic straws for "spouts" are horrible.
So true
Mr Pete I have been out of school for 40 years .I have always said "I learned way more in shop class to help me in my life than any other classes in school" I sure would have liked to have a teacher like yourself back then. However I am now in your class.And thank you so very much for what you and your friends keep doing ,Thank you. Now you just need to keep doing it for 30 more years.
Thank you, I love my shop classes and both high school and college. In 30 years I would be 105
Ditto all those sentiments but the last one. He should continue on for the next 3000 years or more.
"I learned way more in shop class to help me in my life than any other classes in school" . This would be a gross overstatement in my case. My shop classes were usually populated by a few serious students and a lot of unruly dullards. I learned far more in History, Mathematics, Physics, Chemistry, etc. that helped me understand the world outside.
I've been doing this for years & I found the Cratex sticks work very well & they come in many sizes. They are chucked up in the drill press like a drill bit. For the best appearance the spacing is very important & must be uniform to achieve the best results. I've done it on brass, copper, aluminum & steel with great results. You want to practice on scrap material until you get used to the process.
Thanks
Rotary scraping !
I want to do the frames of a Murray’s engine when I eventually get around to building it .
It is use on rifle bolts to give a silky smooth action , the minute scratches hold the oil and make that bolt glide smooth as silk .
What an absolute joy watching and listening to this group of old school craftsman/friends!👏 Stay well boys!
👍👍
Great video! One of the best things about your channel (in my opinion) is that you cover nearly all aspects of shop work. The breadth of your knowledge and ability is impressive - thank you *so much* for sharing with us.
Thank you very much, I take that as a high compliment
Nice to see a couple of guys having some fun in the shop.
Great work, excellent idea to keep the tool from dulling
I never knew what this was called and I wanted to know how to make this for so many years. Thank you.
I love this look, on everything from car dashboards to watchfaces. Thanks for showing how its done!
Thanks
Great job fellas!
I think I’ll give it a try on my 1959 Apache!
Thanks for sharing the knowledge!
Very much appreciated!
Thanks
Always enjoy your videos!!! You have helped so many folks learn so much!!! THANK YOU!
Thank you for watching
Great video, it looks like you guys had a lot of fun.
Yes we did
Thanks for the wisdom ! I am resurrecting a 1940 Buick Century with the engine turned dash panels
👍👍
I've been wanting to try this, now I know how to do it! Thanks Mr.Pete, and Mr.Moynihan !
👍
Another example of, "I know how engine turning works, I dont need to watch this..." *pulls out the coffee can...* ... ... .. . You beautiful bastards...
lol
Sneaky!
He he!
Hi Lyle just an FYI the jeweking on bolts and other parts of firearms is not only for decorative but also for maintaining a light layer of oil in the scratches to help prevent rust and lubricate sliding parts. Similar to scaping on machinery.
Thank you, I did not know that
In watchmaking this process is called perlage, and it is mostly applied in circular patterns on watch movements. . General rule of thumb, advance half a diameter at a time in either direction
Always a joy to watch your videos.
Palmer is quite a creative fellow... On all counts... ;)
Linberg's plane the "Spirit of Saint Louis" the first part of the fuselage and cowling was decorated that way, that made for a real original looking plane...
I remember a very long time ago doing that with a pencil eraser. It was the in thing among metal types I think in the 70's and before for decorating small items like lighters and such.
Used to use new pencils with good eraser with valve lapping compound in a 1/4" b&d all metal hand drill. We never used the eraser on the pencils, always used the white gum erasers used for drafting. Never had the smeared pencil lead marks on the paper. Cut off 1/2" of pencil with ferrel and eraser. Perfect size for engine turning.
Hi Harold. Yes lots of different ways to do it
Hi Mr Pete,
Here in the U.K. We call this surface finish Purlidge, thanks for all the very interesting videos you have uploaded over the years, from Coventry in the U.K.
Thanks for watching
I was just thinking this method might work with a valve cutting abrasive, spread evenly over the surface,, great video and inspiration and another great idea i get to stick in my mental tool box
Have wondered since I was a boy, and being fascinated with the dash on my Fathers 1937 Cord, how this was done. So glad you put this up.
👍
I did this with a small polishing wheel for a pencil grinder with medium clover compound on a Bridgeport with ez trak. It turned out awesome
👍
Never thought of doing it like that, tried this a bit with scotchbrite on aloominum which worked OK but didn't know how one would do it on steel - great method!
Always wondered how that was done, never realized it could be that simple. Seventy-Three and still learning !!!
I am 75 and still learning
I knew what it was, but haven't ever spent the time to figure out how to do it in a good way. Thanks for showing us! Will have to save the tip in my back pocket until I do a project that is worthy
👍👍
Thanks! I always wondered how that was done! I knew it was called "engine turning" but had no idea what the term ment. Now i do! ( I have a 1962 Ford Galaxie with a strip of aluminum across the dash that is engine turned. ) Thanks for all the great videos!
👍👍
Thank You ! I always wondered how that is done. My vintage sprint car has a jeweled dash. Looks great with those old Stewart Warners.
Great demo! I added some jeweling to the aluminum bottom plate of my 3D printer, it does a nice job of hiding scratches.
Awesome
My dad was a NAPA jobber for 40 years. I stocked many a yellow jar of Balkamp valve grinding compound, but my own personal jar somehow vanished. Now I know why. Palmer drove over one night and took it! I’ll be watching next time you cross I-35!
lol
Whoa...you dudes are having way too much fun...I like the idea of using a yard stick to get the spacing uniform!!!
Yes, we were laughing and having lots of fun. There were three or four other people in the basement watching us
Always fun to have others of like mind in the shop..Great time to swap ideas and experiences with guys that love machinery like we do !!!!
I’ve never done engine turning, but visually it resembles flaking and may hold lubrication well and could be done against a stop for level control. Could be used to lower high spots after a component has been in service sufficiently long. Just a WAG. I’ve always wondered how this was done. Thanks for sharing. More likely it was just used to disguise a scratched dashboard surface.
Thanks for watching
Very neat. Good video & once again it was a great meet & greet.
👍👍👍
In the 1950s, I had a neighbor who had his MG-TC modified with a engine turned, stainless steel firewall. That, along with a figured walnut instrument panel, made that machine a real beauty.
Thank you, I liked those old MGs
Thanks guys!! That’s great. I plan on using this on my roadster pickup!
A great new thing to learn. Thank you, gentlemen.
Thanks
Did a stainless island top, used coconut oil, melted, poured, and silicon carbide blasting powder, just fit in my drill press. Oak "tool bit", lol, came out amazing. Thank you.
👍
It wasn't used just for decoration. One of its purposes was to retain preservatives like oil or wax on the surface of metal to prevent oxidation and to provide lubrication retention. This is why you see it on the ways of lathes and milling machines.
I have a 1955 Buick w/ aluminum dashboard trim and so dull that I tried polishing and lost a lot of my swirl but after seeing this video I’m so gonna try to do this. 👍🏽
👍👍
My shop teacher showed me trick. He'd use a discarded piece of wire rope or cable and put it in a piece of copper tubing flush it on one end and solder it now he bandsawed the other end square and chucked the tube end in the press and went to town and we used grease pencils to make a real consistent pattern and he would spray a mist of lithium and then sprinkle with iron powder and when we got done it looked like an automated machine did it!!! I also use a spot weld drill bit with the center almost completely gone and that worked great on small dia. circles and you can use compound with them too, it comes out really uniform! iv'e seen a guy use a hockey puck cutout at low r.p.m. with flitz compound and it looked really sharp!! Oh well! take care Mr. pete
Thanks
That really is a nice looking finish, I had forgotten all about this technique I like the Idea of placing the abrasive on the surface instead of using sanding disks and the like - Thanks for posting and as always Two Thumbs Up Sir!!! or should I say Sir's? lol
Thanks for watching
I guess grinding dust might also work for this kind of job - if you didn't want to buy any grinding compound and were sick of having to throw all that dust in the trash can...
Might give it a try if I ever need to do some engine turning, thanks for this brilliant tip!
Nice demo. Palmer is a great guy...ok, Randy, too. Fun seeing you guys do a video together.
Yes, we had some laughs as we were making that video
Awesome fellas. Thank you. Dad used a wire wheel, I like this idea. Hope you all enjoyed a nice steak meal after showing the how.
Thanks
Thanks fellers! Very informative! Planning on using this method on some guitar parts! Cheers!
👍
Always loved engine turning.
Thanks.
Thanks
Think I will make a spring loaded pad to do this in my CNC- ideal way to do such a repetitive task.
It is alleged by firearms enthusiasts that jeweling the bolt is desirable for lubrication purposes, but to my mind jeweling takes me back to the 1950's and Sears Craftsman tools like a table saw front panel. ☺
I never thought of that, but it would be good for lubrication
Learned a new thing. On a side note, what a great get together. I wonder how much mischief they got into.
Enjoyed this video! Thanks for the info. Going to get my drill press out an have at it on some old brass cymbals I have laying around to see if it changes the sounds quality.
I worked for Diebold Inc for 36 years; between the late 1800s all the way up to the early 1950s this was a common finish on safe deposit box doors and the backside of vault doors. At the time both SD Boxes and VD rear doors were plated with nickel and the finish was referred to as "Jiggered Nickel"
Thank you, now I recall that look on Bank of waltz. Today I took a bicycle ride. They are building a new micro distillery. I looked through the window and all of the big tanks were engine turned
This is interesting. When I think of "engine turning," I'm reminded of Charles Lindberg's airplane, "The Spirit of St. Louis." Its cowling had this distinctive and beautiful treatment. I don't have many applications for this but now know how to do it with comon abrasives and tools. I think equal spacing of the swirls (vertically and horizontally) gives the best pattern.
I remember that airplane
I've always liked that look. Have to give it a try. Looks like some grabass going on!
lol
This used to be done on guns for oil retention as the light scratching holds oil better.Jeweling pearling.Its used on watches.
Gracias, por mostrarnos como se realiza este hermoso proceso 😊
😁👍
A very smart idea wonderfully applied. Thanks for sharing!!
👍
I use delrin and coarse lapping compound . Put round delrin in drill press and apply abrasive
Interesting, thank you.
The early Bugatti dash panels were mostly done free hand, and if you look carefully, you'll notice the imperfections.
👍
I never thought about using the rulers and the wooden dowel with abrasive powder. Great simple ideas. One item that wasn't mentioned is you cannot (easily) backtrack because the pattern overlaps in a certain way. If you have to backtrack to redo a circle, the second application will most likely not match the previous circles. You may have to start over or scrap the project. Try as hard as possible to get it right from the get-go! Practice, practice, practice! Also, I start with half circles along the initial edge and many lines will end, and/or start, in half circles too.
Yes, you cannot go backwards
this looks fantastic on a small scale with watch movements. same idea but much much smaller
Thank you very much. I am going to make my own dash panels now.
Looks like you guys had a lot of fun.
Thanks
Yes we did
I remember my older brother doing this to the dash of his Studebaker. Must have been around 1960 (I would have been around 8 and he'd have been about 25. I didn't get to see it done but afterwards it looked too perfect to have been done by hand. I was amazed. I remember him planing to use something like a pink pearl eraser maybe 1/2" in diam. Want consistency? Just change out the "tool" on a regular basis like maybe end of every row.
Yes
I’ve played around a bit trying that. I used a pencil stub chucked eraser down in the drill press. Worked pretty good.
Yep, there are lots of different ways of doing that
The old gezzers always know the best 😁😁 great job guys 😁😁🤘🤘🤘
Here I am four years later watching this process again.
lol
I often use pencil erasers chucked up in a drill press with valve grinding compound slathered on my part. Works great.
I learned how to do this at a knife shop i worked at for awile ...they called it "fish scailing" and also have heard of it refered to as dragon scail.
Thank You very interesting, have a few projects I would like to try this on. Great video!
Thanks
I was told years ago by an old man that has long forgotten more than I ever hope to know the reason why they done that on fire trucks and such was to hide the wavy panels.
Thanks that's good to know, but kind of disappointing
fantastic video, mr. pete - thank you!
Thanks
Looks much better than the fake stuff. Thanks for the video!
Yes
Jewelling is used in fire arms for holding oil and improving lubrication
Thanks
Great video thank you for sharing 😀
The Pontiac Trans Am from 1970 to 1981 have the true engine turned dash bezel. Im very picky doing it. I also polish the aluminum to a mirrored finish before the turning. And use valve lap .
Thanks
A video worth watching. Respect...
Great vid 👍🏻👍🏻👍🏻👍🏻 now I'm going to do some turning on a few things Fantastic tips it's simple and it works👍🏻👍🏻
Thanks
I have used engine turning to aid in holding oil between two sliding surfaces.
Yes thanks
Great video!!! thank you. Looking forward to more!!
Thanks
Watch makers use this a lot to decorate the insides of watches. You can also hide surface scratches using this.
Yes, I have seen that. It is beautiful
Agreed, I watched a vid once where a watch maker did the grinding by hand along curves. He used a small tool that looked like a mini valve lapping tool with a soft rubber tip smaller than a pencil eraser dipped in abrasive compound. Results were amazing. IIRC it was a documentary about the Rolex factory.
I always liked this but never knew what it was called or how it was done. Thanks for the video, teacher!
Thanks
If you want to do small parts with maybe 1/8th inch (3.2mm) turns, try an eraser pencil. It´s just like a normal pencil, but the "lead" is very stiff eraser material. Just sharpen it and cut the eraser off flat, chuck it up and use light pressure. Did that on the chamber of a small blank pistol, looks quite nice, although material is zinc and gets dull over time.
Thanks
Nice one guys
Thanks
I love the turning work on the Craftsman, King Sealy power tools.
👍
@@mrpete222 just picked up like new 3 wheel bandsaw at power show flea market in Wellington Ohio😁
Good job!
Thanks
Yall are having lots of fun! You can also use toothpaste to get the oxidation off of head light lenses as it is fairly fine grit.
Thanks, I have heard that
Oh man. something else I wanna try. Cool stuff.
Mr. Pete,
Perhaps the most known example of engine turning was on the cowling of The Spirit of St Louis, the airplane that took Charles Lindburg for the first solo crossing of the Atlantic.

Thank you for watching
mrpete222 I can't get enough of your video's That goes for your esteemed guest Randy Richard as well
When you see a piece of a broom handle mounted in the tool changer on the mill now you'll know why. :D
lol
I read somewhere that jeweling covered up scratches on parts that would see some wear. It is pretty!!
Maybe that's why it was used on watcher
I meant pocket watches.
This was great you should gave so many more likes guys .. you’re awesome!
Thanks
