New RAF style dial creation


Recommended Posts

I presume it uses a digital printer somewhere along the lines as there is stair-casing on the curves such as the number “6”. Still looks very good to me. 
 

By the way, “W10” is an Army designation. It would be “6B” or latterly “6BB” to denote flying equipment.

I've seen some fantastic artwork done on custom motorbikes during my time with clubs. It gives the impression it is airbrushed by an artist when in actual fact it is done by transferring a print image off paper.

You print a mirror image on paper and then apply a transfer gel medium to the metal surface. You then apply the paper to the gelled area ink side down and leave it to dry. The next step is to soak the paper and rub it off with your thumb like removing a sticky label residue from a tincan.

Two issues to deal with as I see it. 1),Could you print a suitable 'skeleton' image (e.g. 'chapter' or 'railtrack' only) and 2), I'm guessing you will end up with a matt finish although maybe gloss lacquer will solve that.

The other thing is, to my knowledge, you cannot recreate a metallic colour with a printer such as silver or gold. Hence you end up with solid colours as per the OP's photos.

Dials not for sale

That's good that they're not for sale because had you've offered to sell me a dial  I would've reported this discussion to Mark as you would be in violation of the message board rules. There's a section in the rules titled "Advertising, self promotion and posting links."

As someone else pointed out were an open discussion group we share ideas and knowledge. You asked for our help you need our feedback and you don't want to share other than look what I did isn't it nifty. Just my personal view that doesn't seem like you're embracing why this group is in existence.

I'm intrigued, and even though toptime810 is a little cagey about his methods, that wont stop me from speculating.

Ignore the fact that the video in the link below uses a lot of expansive hardware, the basic idea that I would like to explore is the thermal transfer films. Ignore the fact that youtube embedding is currently not working, I'm sure that will be fixed soon.

This is one of a bunch of techniques I would be keen to apply. Thermal transfer films allow the use of titanium whites, metallics and a bunch of other stuff that would be pretty difficult to do any other way. You can also get some small rolls of thermal films from ebay, and application could be with something as simple as a clothes iron or a pouch laminating machine.

How much would your idea add to the thickness of the dial, would you still be able to fit the hands ok?

The thickness wont be much I suspect.

The way the films I looked at typically work is by adhering to toner, so you print, or transfer your laser or copier toner design on to the brass or whatever your substrate is, then you put the foil on top of  the metal substrate, pass it through your heat source, and the foil bonds to the toner (which melts and becomes tacky due to the heat, as heat bonded toners are designed to do). This changes your black toner design to gold, white, metallic, holographic, or whatever your film produces.

This means that the layer is likely to be a few hundredths, or even thousandths of a mm or so. The actual thickness will depend on the density of the toner, and the thickness of the bonded layer from the film, but we are talking pretty thin.

Here is an academic paper on toner thickness which gave me the ball park figure for the base toner layer. It talks in terms of μm or micrometers (thousands of a mm or 10^-6 meters if you prefer).

Search for information on "laser transfer foils" and "hot stamping foils" if you want to learn more about the idea.

The hardest part of this 20 step process is drilling the chrono hand holes with precision without out $20,000 equipment. Then comes the lume and casing process. Everything has to be precise or it will not work. I had to make 30 dials just to get two that are perfect enough to work for the case and movement.

You might get some use out of a small cross slide, it would allow precise and repeatable alignment.

Search ebay/ali for something like 32mm Metal Cross Slide Block. Expect to pay around $20 to $30 for something cheap from China, which would probably be good enough.

Couple that with a pre-drilled clear plastic alignment drilling template, and a base plate to hold your blanks precisely and you should be able to get repeatable results.

You might need two for complete x/y control. Mount one on the other, and bolt the lot to your drill stand.

    • HWGIKE#57 Valex FEF 190 15 jewels Swiss lever full service and repair This one was waiting for a balance staff replacement in my cabinet parts and case cleaned up with a new balance staff and a 4th wheel as the original 4th wheel had a broken pivot for the off center second hand. I never attempted a balance staff replacement before however I received a Bergeon Molfres (i was hunting it for about 2 years) and with the help of it I managed to remove the old staff and riveted the new one in. It also received a new MS, crystal and the hole for the MS arbor was also tightened. With the new MS now it has an acceptable performance meaning that the amplitude goes up to 280 fully wound, has an acceptable beat error and I have the two nice lines but only dial up, dial down is not as nice and I could not figure out as why. I have the two lines but the amplitude is dropping to around 230 and the lines are a bit hairy. Both dial up and dial down the lines just go up and down without seemingly any pattern. I cleaned the movement two times, and then a 3rd time pegged out the main plate and train bridge holes but made no change. Both the HS collet and the roller table was too lose on the new staff... I did not count how many times I took the balance cock off to sort out the HS collet, the roller table and the beat error, somebody before me also shortened the HS by pushing it out a bit and it seems every time somebody is messing with the end of the HS the protruding bit is most of the time twisted bent etc. This one was probably one of the most challenging repair and service. I might take the new MS out and clean it lubricate it as I just pushed the new one in to the barrel from the retaining ring. Plus started to re-read the theory of the escapement and how to analyse the graph on the timing machine: Greiner Chronografic Record manual. I am also thinking to put the watch on a 24 hour long run with the eTimer SW it once helped me to figure out what was wrong with a watch. There is an interesting part of the Greiner record manual talking about the pallets and the end shake of the balance and pallet staff. Maybe this is my issue? Who could that possibly identify? After a few years now I am still without a clue how could watchmakers make parts I can only see with my microscope or how could/can they carry out complicated services impossible to do.. real magic..... .... ..... before I sent this post while the pics were uploading I had an idea, i was browsing the possible outcomes on the timing machine I had one for magnetism..... so I demagnetized the movement and it is not hairy now.... two really nice lines 0.2 ms beat error still a bit wavy, but a lot lot better..... argh....  
    • Hi there, welcome here.  
    • yes the advertising revenue should generate money. The question is how much money? Then as far as the cost of the website goes that's relatively easy to determine? all you would have to do to grasp costs and profitability would be to go to the link below and you can actually get a website for free try it out for free I believe you get no advertising initially. They also talk about that they'll help you out they have marketing tools and some sort of paid subscription or something. So I guess were shopping for a whatever just ask them what would a maybe could use this one as an example in other words it's going to look basically identical to this is going to have advertising a paid subscriptions what's it going to cost? After all they want to sell or give us a message board like this they should bill answer the questions as they're the people who did the software for this. Yes they really said you can have a free discussion group at least to start. https://invisioncommunity.com/ I was curious about the monthly supporter thing where exactly do we find that on this message board? A quick search I'm not finding it so obviously I'm not looking in the right place?
    • Help me out here, but with all the advertising on this site (which I don't mind) wouldn't it pay for itself or even make money for the owner ???
