At 11:23: Aluminumis a great conductor, but Al2O3 (Aluminumoxide) is a great insulator. That means you need to penetrate the oxide layer first before current can flow. Probably sanding the oxide layer down and preserving the surface with oil - to prevent a new oxide layer would help the etching.
Another great video sir, I love your stories and tales. History will be lost if its not told, and even small little stories like these will keep memories and names and places alive. Thank you sir.
Thank You Tubalcain ,I love a good history lesson . Santa Monica Ca. was once a manufacturing hub , machinists ,welders ,sheet metal craftsmen , and now has turned into ????? But anyway , I enjoy the smell of the old oil being heated up . Bravo !!!!!!!!!!!
Yes, I think are still in business. My mentor had an old soldering unit. I bought one 40 years ago and still is going strong. It is great to solder fine wires. It puts the heat right where you need it. It is absolutely the best way to solder music wire. It is simply a negative ground and then an positive tip you solder with that using a carbon arc rod. Thanks for the video.
+mrpete222 IT doesn't really matter what they do as long as they interact with your channel. As far as your mind goes, it's a thumbs down. As far as RUclips goes, it's interaction on your channel and it's a good thing.
When I worked at Dresser- Cleco in the 90's we found another good use for the resistance etchers , brand new carbide bore bars are 10 to 12 inches long and for smaller CNC lathes this is WAY to long ! So we would etch around the circumference about 7 to 9 times & then chill them in a water fountain , the strike them on a steel corner of a lathe tool . almost always broke pretty square. Those were the days , when we intentionally broke a new tool and didn't get fired or reprimanded !!!
Hey Mr.Pete In the late 1960's I was an apprentice mechanic. I bought some Snap On wrenches that cost a bunch. The other mechanics and I purchased an electric buzy pen. To use it you placed the metal object on one battery post and a jumper wire between the battery post and the item to be etched by the tool. The electric flow through to permanently etch the item. Even if some jerk tried file the image it was still visablle
The last 27 years of my working life was in Radiation Protection. There are still radium dial watches available on ebay. A worker at the plant bought one and tried to wear it into the plant. That did not go well. Had the plant locked down for an hour, 'til we cleared it. I may try to build my own resistance etcher.
Wow, Had not seen one of those in many years. We had one like that [made by Martindale Electric Co, Cleveland, OH USA] in the tool room I had worked in. It can also be used for etching a "break" line for breaking sticks of tungsten carbide blanks to size.
Lyle, I really like that gizmo. I too have an affinity for marking what I make. I have the stamps, the vibrating pencil, now it looks like I need to be on the hunt for one of those, LOL I am sure a man who is a skilled draftsman could easily have marked your inspection rig. My lettering is pretty good but I have worked with men who wrote like typewriters. Shame I cant get most of my kids to letter any better than a second grader on their drawings. All the best! Mike
Out of passing interest... the etcher switch knob is a variation of a whats called a 'Chicken Head Knob'. They're still made in all sizes & flavors; pretty sure most from back in the day were Bakelite... check amazon and/or eBay. (I think they still come stock from the factory on some Simpson multimeters.) Also, back in the 70's we had one of those Luma Etchers in A&P school... looked much the same, wiring and all. We never had use for it, and it didn't appear to have been touched in decades.
A lot of information in one video. How about a short follow up video and see if you can measure the open circuit voltage and the voltage when you are etching. If you have a clamp on amp meter the current when you are etching would be good information too. Thank you for all the effort you put out to make the videos for us. You may be the last true industrial arts teacher still actively teaching!
I plan on it. For a moment I thought I had a conflict. Hope to see you there. Right now I am planning my annual trip to the "Threshery" in my home town of Milton (Edgerton, WI). That is always Labor Day weekend. I know you have gone there too. If you plan on stopping there then let me know. I will go to Arnfest on Sat Sept 23. Another note: I am looking for a good set of Woodruff keys and cutters if you or a friend are looking to sell.
I used a crude version of that made by snap on I think . I tried to find one for years and It was obsoleted and no longer avalible and the guy I borrowed ir from would not sell it. Absolutely the best for engraving tool. Great vidio.
I wonder if you would measure the voltage across the etching leads? Also, it would be interesting to know the amperage used on the line and the leads. I would imagine they reduced the voltage and therefore increased the amperage available (if the transformer windings would handle the current). Greg
Hey there Mr Pete, I was lucky enough to pick a similar unit up here in Australia for $25.00 about 5 years ago. It works perfectly, but mine uses Tungsten for the writing tip. Upon research when I first acquired the machine I found that it uses the green Tig welding tungsten's. I have a feeling my etcher was built in the 1960's but that is just a guess by it's design and style. I have seen many milling cutters and reamers etc etc people have etched and the quality of handwriting is stunning. No matter how hard I try to replicate it my attempts fail. So I wonder if there is some form of template they used or some such similar thing. Keep up the good work Mr Pete, your new format of video where you have decided to show your face has made the video so much more personal and I for one like it. Regards from Australia.. Matt
Thanks for another great video mrpete, I had never seen resistance etching b4. Love the jokes and all the free info😀. Thumbs UP for sure. And yes you are my RUclips shop teacher. Thanks again. Steve Summers
The type we had at work had a thin bar which the electrode would screw to, this had the effect of vibrating as the spark made contact and would not stick to the work. It was mainly used for marking tools as the grinding shop had acid transfer etching. Maybe you could make up an attachment like this for your handheld electrode?
When you get that pop and sparks, is it creating a fine pit along the line? What causes this? I ask because I have a vintage rifle with very fine markings in the bluing. So fine that the markings were typically lost in a factory reblue. I did notice two things, the grain in the metal was retained which indicates a form of electro/chemical etching, and the lines would typically have one tiny pit. Glad I watched this one.
Here in CT. those poor women are known as the Radium Girls. We had a huge clockmaking industry here and the damage caused by radium is well documented. The photos of the damage caused due to exposure are horrible. The clock industry is now gone but the huge factory buildings remain. Many of them have been converted to apartments. About a year ago the NRC - Nuclear Regulatory Commission decided to re evaluate these buildings due to their past exposure to radium. One such complex that was converted to apartments 35 years ago has fallen under their microscope and is in my hometown. 2 years ago the complex was mostly full - - now it is mostly empty and has a large billboard out front trying to attract tenants. Bad news spreads fast thanks to the U.S. Govt.
White Master Mariner Someone has to teach your children, and public education is mostly how it's done in the US. There's a significant difference between a classroom teacher and a bureaucrat, though they are both publicly funded. There's also a difference between the Federal debt and the mostly state funds that paid Mr. Pete's salary.
Mr Pete, May I suggest that you replace the asbestos wire as soon as possible with silicon insulated wire. I probably don't need to tell you the disastrous effects of asbestos fibres to your lungs. As a person having worked in an industry where asbestos was all around I have seen to many colleagues die prematurely of asbestos fibre cancer.

Great video Mr Pete, LOVE the almost forgotten historical info and history you bring to light - im a serious buff of the "greatest" WWII generation and ive seen detailed shows and read about the radium girls. What a story, sad but true these workers weren't more well instructed and protected from such lethal materials. I only recently learned one of my favorite aunts was an employee of the US naval department, found out as I inherited all her property and have all her paperwork. I found pay info and hiring letter, classification code etc. referring to her employment, but in all the years I spent with this wonderful woman I don't recall if she ever mentioned working for the govt. or what she even did there. Knowing her strength of character im certain she did her job well. She also worked at the Chicago Wilson sporting goods factory in the sixties when I was around six years old or thereabouts and she used to bring me home "seconds" from the production line, I still have a junior boxing glove she gave me and I sure miss that woman she treated me like her own child and had rock solid integrity. Please keep the historic info coming, its far more interesting than anything on tv today - I cut my cable cord years ago and watch antenna tv just like it began so many years ago.
I must have the grammar nazi disorder, because I had to pause and zoom in on the video and ask myself if I’ve been misspelling Tubalcain this whole time. You got me.
Radium's most stable isotope, radium-226, has a half-life of about 1600 years. It decays into radon-222 through alpha decay or into lead-212 by ejecting a carbon-14 nucleus.

What kid wouldn't want to play with that? Sparks, noise and you can mark your presence. I know you said they are industrial grade, but I could totally see a kid writing on everything metal with this. I want one.
"you can't get shocked because it's grounded... oh wait it's not grounded!" XD nice! awesome videos; I enjoy your channel. Don't worry about the trolls. They live in a far away land that can't harm us.
The fact that I've watched most of your videos, and this one too should not confer any type of expertise to myself on Your video production methods All I know is that they constantly entertain & inform,a most positive experience. K.U.T.G.W.,T.C.
The,aluminum is hard to etch because of the coating of aluminum oxide (alumina, corundum). It's transparent, hard, a good insulator, and a good protection against further oxidizing (which is why a highly reactive element like aluminum is still quite weather resistant). The coating is brittle and very thin, so you can scratch through it (even with a soft copper electrode) and reach conductive metal. The aluminum so SO reactive that the alumina coating is reformed within seconds after exposing the bare metal. (Cool video; I ordered a used Luma etcher - different model and not a good a deal - off eBay while I paused the video. You have to be quick; when someone interesting mentions a tool in a RUclips video, they suddenly get scarce on eBay.)
What about reversing polarity Will it make a difference how it works Went thru 2 snap on versions of resistance engravers during my career of 37 years as a heavy duty mechanic Never thought about it The ones snap on sold were 12 volts just hook to battery
I remember my mother telling me stories about young women twirling the paint brushes on their tongue to paint instrument faces with radium at the Bulova watch company in Astoria NY where she grew up.
I worked in Bulova's dial dept., as a lab tech. They used tritium, NOT radium, for the luminous dials. Also, no brushes used in application. Still, tritium is radioactive and the workers had their urine CAREFULLY monitored. BTW, the plant building is on Astoria B'lvd in Jackson Heights, NY. Eli D.
What is the insulation on the kinda white wire made of? could it be the A word - ours at college was and at Boeing plant #1 also. I'm was an industrial arts teacher long ago - I'm 75 now. Keep up the great videos.
I only guess, but aluminum is coated by very hard layer of oxide. It melts in much higher temperature. That's why welding aluminum is so difficult. Try the fresh cut.
Here In England we call them Electric Pencils. BEWARE, the WHITE lead looks like ASBESTOS to me. It needs to be heat resisting cable due to it getting hot when etching. Please change it for a Silicone cable or fiberglass one.
And another thing, I remember seeing a show on those girls, some of them would bring that glowing poison home and use it for fun with their husbands, alot of men also kicked the bucket because of that mess. Thanks. Again.
Ellie Price that is the input voltage at the plug where it goes into the wall. I’m wanting voltage at the etching tip. Most likely it’s converted to DC voltage like a mig welder.
If we get a worldwide power outage, your city will be one of the rare ones that will probably light up in the night and be visible from sapce... Think about the brite side, for at least million years... lol
At 11:23: Aluminumis a great conductor, but Al2O3 (Aluminumoxide) is a great insulator. That means you need to penetrate the oxide layer first before current can flow. Probably sanding the oxide layer down and preserving the surface with oil - to prevent a new oxide layer would help the etching.

SO, That's your story and your sticking to it (Tubualcain). Like the video, keep'em coming!
Thanks for watching.
You can make perforated (pounced) paper patterns with that tool, also.
Radium dials were used in all WWII aircraft instruments.
Much younger I was wearing one of those watches, I'd look for any dark place to enjoy the dial lighting up... If we only knew... ;)
Thanks for watching.
Excellent info. I never knew that unfortunate bit of history about Ottawa. For a short while I lived right down the river from it in Marseilles.

I think the lettering was done with a LeRoy lettering guide using an adapter for that pen...
Could be.

What about reversing polarity
Will it make a difference how it works
Went thru 2 snap on versions of resistance engravers during my career of 37 years as a heavy duty mechanic
Never thought about it
The ones snap on sold were 12 volts just hook to battery
Unfortunately, I sold our last summer. Wish I had not
As always:
A most informative and enjoyable video.
Jesus bless you Lyle for what you do for others.
Thanks for watching.
Hi Mr Pete from Australia
love the video most people wont know what a rim shot is
+ Jerry. Lyle is saying GRIN shot, that was why he got his phone out and showed a picture of him with NYCNC GRINNING.
Great video to funny i have the same brass handle that you tryed to write on lol😂
I remember my mother telling me stories about young women twirling the paint brushes on their tongue to paint instrument faces with radium at the Bulova watch company in Astoria NY where she grew up.
I worked in Bulova's dial dept., as a lab tech. They used tritium, NOT radium, for the luminous dials. Also, no brushes used in application. Still, tritium is radioactive and the workers had their urine CAREFULLY monitored.
BTW, the plant building is on Astoria B'lvd in Jackson Heights, NY.

I guess all clock companies had that problem--Thanks for watching.

Thanks for watching.
I'm the bumbler who never took shop as a kid. They had restricted spaces. So I have (and many others have) learned a lot from you. THANKS!
Most excellent! I like all your tangents and aside information.
Thanks for watching.
Mr pete is that etcher a transformer and is it dc out put
tell the trolls to go watch satellite cable your the best mr pete!
yes--HBO
Love your stuff Mr. Pete. So what is it Tubalcain or Tubulcain as you etched it?
Great video ac or dc 🤔 i am assuming ac but you should check it ease
Would of enjoyed a quick look inside it. Good video though.
Thanks for watching.
Lyle is correct, it's probably just a transformer inside, although there might be some divider resistors selected by the switch.
What is the insulation on the kinda white wire made of? could it be the A word - ours at college was and at Boeing plant #1 also.
I'm was an industrial arts teacher long ago - I'm 75 now. Keep up the great videos.
Yes, it was the a word. Good to hear from an old shop teacher. I am 77
I only guess, but aluminum is coated by very hard layer of oxide. It melts in much higher temperature. That's why welding aluminum is so difficult. Try the fresh cut.
Thanks for watching.
did their eyes glow in the dark?
no--lips
"Every man for himself" LOL Yup, we had to be careful on our own.
Good video.
Thanks for watching.
Here In England we call them Electric Pencils. BEWARE, the WHITE lead looks like ASBESTOS to me. It needs to be heat resisting cable due to it getting hot when etching. Please change it for a Silicone cable or fiberglass one.
And another thing, I remember seeing a show on those girls, some of them would bring that glowing poison home and use it for fun with their husbands, alot of men also kicked the bucket because of that mess. Thanks. Again.
I wonder what the voltage is ? DC I assume? I really don’t know.
not sure
Says 115 right on the end of the box
Ellie Price that is the input voltage at the plug where it goes into the wall. I’m wanting voltage at the etching tip. Most likely it’s converted to DC voltage like a mig welder.
Thanks Tom and Kevin. Looks like low tip voltage and high amperage to produce a the hot etching spark.
I like this thx for posting

خلاصه یکی نیست چطوری کارکردشو واسه ماهم توضیح بده
Thanks for watching.
Hah, for a while there I found myself questioning how Tubulcain should be spelt!
Thanks for watching.
Why are you etching on and antique Fuze calibrator? It sould be in a musem!
Antique, yes. Valuable, no! It is little more than a conversation piece. Likely more valuable as scrap metal with all that brass in it.
Very true---but it will soon be in the westclox museum
have an old snap on marker runs off a car battery ,coil is built in handle,gets very hot
Thanks for watching.
Why did you spell it Tubulcain on the part, when all your videos spell it Tubalcain?
To bull, or not Tubul. That is the question.
lol-Thanks for watching.
First "nipple clamps" and now "fetish." Egads! Where is this going?
lol
If we get a worldwide power outage, your city will be one of the rare ones that will probably light up in the night and be visible from sapce... Think about the brite side, for at least million years... lol
LOL
I would be scared to death of that damn thing.
Thanks for watching.
Just in case anyone really cares, the half life of radium is closer to 1600 years, not 1,000,000. Still nasty stuff though.
Thanks for watching.--Now I feel better
Great news that in a million years it will be half as bad!!
lol--Thanks for watching.
