Well, it's a good thing you went with a two-headed coin instead of a two-tails coin. If you'd done the latter, that would have meant de-facing currency.
I think i'd have oversized the insert. Or undersized the inner diameter. Then heat one side to a few hundred degrees. And drop the opposite side into liquid nitrogen. Once you put them together you'd only be able to cut them apart
@@joelsmith3473 He can't even spell tea so I wouldn't worry too much. $5 divided by $0.2/KWh divided by 60 minutes is 1500000W power consumption. That's about 500x what a power outlet can provide.
Psst. Same goes for paint brushes. Instead of washing it out just to reuse on same paint later. Just put it in ziploc bag in the freezer. Personally this has saved countless hours of my time.
Very cool. Are you not supposed to hide the secret spy microfilm inside the hollow coin before assembly? I admire your custom collet, good work. Another option for adhesion when machining is to use watchmaker's shellac and heat from e.g. an alcohol lamp to adhere the part to a faceplate. Melt on, machine, melt off. Available from purveyors of watchmaker's supplies.
Great video! A couple of things: If you heat up the piece, you can get the superglue to release on it's own. Not too important here, but very helpful for pieces smaller than the superglue chuck they're attached to. Also, it looks like running the superglue chuck off-center created some significant shake in the lathe (or the tool, can't tell which). Did you measure any run-out in the insert face? It might be worth bolting the lathe down or moving to a sturdier base if possible. All in all a fun project though. I'd probably have cut with a smaller compound angle to get a better finish on the insides, but no one's going to see it anyways so it's just to satisfy the mind. :) Love your content, keep up the good work.
how do you do this if you are making a brass coin? Brass has similar properties as copper. I'm doing a coin project right now and just parted off the coin... now I need to turn the parted off side. I was going to use CA glue to hold it to the piece I just parted off from... Suggestions?
@@LuciferTJ I used two coins, a 5c emergency collet bored to spec.,then soldered the two half’s together. The feel of finished coin was great but the weight was the tell.
@@dennyskerb4992 If you also hollow out the second half you can add a small amount of tungsten powder to regain the weight, using a third untouched coin as a check. Probably best to use a drop of something like lacquer or molten beeswax to keep it from wearing away the inside.

I actually found one , I was trying to buy a soda and the soda machine kept spitting it out. I took a better look at it and said, wow it's a two headed quarter. I thought I was rich, googled it and found out it wasn't real. I got drunk and accidentally used it at a bar to play pool.
You could make outer part gap just a tiny bit narrower, then heat it up, then put inner part inside. As soon as they come to equilibrium, they are locked forever. Without glue🙄
@@CM-xr9oq brass (and similar metals) thermal expansion ratio is 15-25 microns per meter Celsius degree, or ~0.3..0.5 micron per 2 cm coin Celsius degree, so heating by mere 100 Celsius would increase width by 35..50 microns. Seems this difference can be easily machined. (If you heat by modest 200 Celsius, you get twice the difference. (Would be great if someone double checks my numbers).
I worked at a machine shop but can't do that. Very cool video highlighting your skills. How much to make one using silver coins. I can buy one but they are not silver on the ones I found.
This just spoke to my soul as it is 3:58am here currently and I have no idea why I'm here lol 😂 so tell me this Stu, since you've got a year head start on me, does it get better? Or are you still easily found at 4am watching videos that have zero relatively to your life?
If I was gonna make a coin like this I would probably get confused and mix one of the coins up without realizing and then be left with one tails side and one head side....
@@sharpfang the way currency works tho , it not in quantity of metal as that by value is less than ten pence as it a alloy blank , it has the queens head and a date stamp that makes the coin have the pence value
Because it's pretty much impossible to adjust the centre of a workpiece in a three-jaw chuck. See all that stuff he did with the depth gauge? Yeah. Might want to watch some This Old Tony videos.
Not bad for an amateur but this is a very long winded process compared to a crafterperson's precision way of machining the coins (about 12 to 15 completed double headed an hour), and which doesn't require any glueing whatsoever. Though i would give 5 out of 10 for effort.

Straight-up illegal to destroy coinage in the UK , isn't it?... Under Section 10 of the 1971 Coinage Act - No person shall, except under the authority of a licence granted by the Treasury, melt down or break up any metal coin which is for the time being current in the United Kingdom or which, having been current, has at any time after 16th May 1969 ceased to be so.

Oh, oh my god, oh
Thats not her real face anyway!!!
With tolerances like those, I suspect the only glue you needed was the Van der Waals force.

2 coins to make 1 coin with 0 value
I love it
It has the value of always winning coin tosses
They sell at magic shops for about $20
Pretty sure it can be used as normal currency and no one will bat an eye if they don't care to inspect it closely.
According to economics value is subjective, many people would pay little and some may pay dearly for something like this.

I've also found it better to store it tip up. My bottles fit nicley in the cup part of an egg carton and it keeps them from falling over.

Well done. Definitely better quality than my double headed quarter.
you show some exceptional skillset here, makes my morning flakes more crispy, post more!
missed opportunity to sneakily switch out the coin and have it land on tails in the
last shot

Better learn to palm a two-tailed coin too, just in case.

Excellent techniques displayed.
I like your method, I just machine my coins in half and glue the half’s together the seam is on the side but it is hard to see.
Don’t use CA glue with copper type coins. (us) Copper holds heat from friction and will debond real quick.
how do you do this if you are making a brass coin? Brass has similar properties as copper.
