Byzantine Sundial-Calendar - Part 6 (Etching & Waxing The Dials)

I use 4 x 20W Nelson brand CFL's, so 80W in total, at a dstance of roughly 350mm - Cheers :)

I’ve been doing etching on brass and copper for a couple of years using thermal toner transfer and a couple of different mordants. Mostly happy with results, but always some flaws. From your work, it looks like more careful surface prep would help, but I’m also considering adopting your photo etch process. I think I understand all of it enough to give it a try except the power of the UV bulbs. You use several I see, what is the total “wattage”? I’m considering using UV LED sources; they come in 10 and 20 W values. Thanks, and keep up the startling beautiful work. You, Uri , and Tony are the three ‘tubers who always put a smile on my face AND teach me something.

Brad Thayer

Hi David - I expect that it will be a software thing. I use Inkscape, it works great and is free. Also be sure to install each of the fonts used in the artwork. Links to both are in the video notes above - Cheers :)

Clickspring

More... the pdf format seems clean on the other files you have loaded. SVG varies depending on the application I use.

David Paterson

Hi Chris, I have been attempting to get a workable copy of the southern hemisphere print from the SVG file you have provided. Unfortunately it is not presenting a workable image, containing additional artefacts or missing radial lines and some circles.

David Paterson

Awesome mate, I'm so pleased :) I'll make a note to add something to the drawings re the screw positions - Cheers :)

Clickspring

HAd to remake the eclipse idler cock this week as the small screw fouled the larger wheel. Not sure if this is covered in the videos in placing the screw locations, but might be worth a construction note in the plans. Either in the assembly, or more likely in the plan view that also shows the clearance circles that define the inner shape of the cocks. All good stuff, the small bearings are a little off position, but gearing still smooth. Haven’t tackled the etching yet. Did like your finishing approach, but you videos do not indicate time required. Perhaps a candidate for an episode of ‘slow TV’ on SBS?😁

David Paterson

Hi chris

David Paterson

All the way to 2000? I've been stopping at 1200, thank you!

Cade Zibkowski

Hi Cade, generally its a case of moving progressively through the abrasive paper grits (400/800/1200/2000) until you get a scratch free finish, and then switching over to the polish. There is much to consider to make this happen successfully and I will cover it in detail in a future TGT, but in the meantime I use Matador brand carborundum abrasive paper <a href="https://amzn.to/2IAFiBT" rel="nofollow noopener" target="_blank">https://amzn.to/2IAFiBT</a> and the polish re-developed by Bill Smith <a href="https://wrsmithclocks.com/product/rub-n-brite/" rel="nofollow noopener" target="_blank">https://wrsmithclocks.com/product/rub-n-brite/</a> - Cheers :)

Clickspring

Do you have some input on how to remove fine scratches from metal in prep for polish? A link to some materials maybe?

Cade Zibkowski

Seeing San Francisco on there really made me smile. I missed the chance to vote and I saw it was a reserve, so I'm so happy to see it making it there

Targe Radick

Thank you mate :)

Hi Rich, yes its a common problem due to the shellac being soluble in most PU coatings - the old timer description of the problem is that the wax is 'crying', although I think the term would equally apply the adjacent clockmaker! The trick to getting it on is to do it with a single wipe - here is a demo of what I mean: <a href="https://youtu.be/qpy5O0b7cL8?t=477" rel="nofollow noopener" target="_blank">https://youtu.be/qpy5O0b7cL8?t=477</a> A second wipe will definitely smear the shellac because its so readily soluble in the lacquer, so it really is a one shot operation. Another option is to use micro-crystalline wax (Renaissance) and lightly seal the dial that way, although I'd recommend a test to get a feel for that process too - its easy to overdo the wax. A third option is to do what I've done with the BSC and just leave it to slowly patinate, if that suits the nature of your project - Cheers :)

Clickspring

Chris, I used the process and steps of your video for etching one of my own projects. Generally it went well but I was horrified to discover that the final lacquer coat reacted with the dial wax and lifted it away from the work piece :( What Lacquer do you use and are there multiple types of dial wax of different compounds? Thanks and Happy Holidays - Rich

Richard Henderson

Hello Chris, nice finish, in fact I argue that the finished quality of the dials seems somehow even better than the print-out acetate... When I made my Antikythera Mechanism replica <a href="http://eternalgadgetry.com/gallery.html" rel="nofollow noopener" target="_blank">http://eternalgadgetry.com/gallery.html</a> I used a hand-made font that very much resembles the original. Take a look, and if you find it interesting, just let me know ;)

Markos Skoulatos

Beautiful work Chris, TFS G :)

Graeme Brumfitt

Thank you!

Clickspring

Congratulations on the reference during a Tested 1 day build video!

Alex

Hello mate - yes that's correct; I'll cover that all off in the last episode - Cheers :)

Clickspring

Hi Chris, Have I missed something, or have you not yet published drawings for the lock spring/control and the gnomen etc? Looking really good though!!!

David Paterson

Definatly worth considering. I saw this system years ago on a wood lathe. That instance allowed you to clamp a pattern to the flat table an then simply follow the pattern with the 'hockey puck' part of the tool holder. the puck need a finger directly beneath the cutting point of the tool. Using that idea you can easily make several copies that are very close. I have made a tool for dropping a turned profile onto a plan that does this in reverse: a vertical knife edge has a pencil point aligned directly beneath. When you this along a part the tool effectively transfers the shape of something like a chair spindle onto a pattern. it was used to project patterns for a baloon backed chair i've yet to finish - but that bit worked ;-)

David Paterson

Terrific idea, well thought out by the looks of it - Cheers :)

Clickspring

Hi Chris, I have no affiliation with these guys, but I saw this lathe attachment and straight away thought of you with your hand gravers! <a href="https://www.youtube.com/watch?v=Xs8XZ8X1I-g&t=951s" rel="nofollow noopener" target="_blank">https://www.youtube.com/watch?v=Xs8XZ8X1I-g&t=951s</a>

Thanks

Vesa-Pekka Palmu

Certainly mate, you can pick it up from most clock supplies shops like Meadows and Passmore in the UK: <a href="http://www.m-p.co.uk/buttonbuy.htm" rel="nofollow noopener" target="_blank">http://www.m-p.co.uk/buttonbuy.htm</a> search out 'dial wax' - Cheers :)

Clickspring

Could you tell where one might get some of the black dial wax? I do cnc engraved nameplates for my scale models out of brass and that wax would look good on them

Vesa-Pekka Palmu

All good ideas!!

Clickspring

Already can't wait for the next project! What is it going to be? Cuckoo Clock? Steam Clock? Gyroscope clock? (a high speed, high precision gyroscope keeps the same direction, while the earth rotates once per day, making the output a 24 hour clock). A one-off series (couple episodes) would be to build a stirling engine, that would also be quite interesting.

Rene Schickbauer

Thank you mate :)

Clickspring

Thank you Jason :)

Clickspring

Thank you mate :)

Clickspring

There is something so satisfying about seeing those fresh etchings pop out from (pop into?) the surface as you wipe of the resist. Great work as always!

Your work is ridiculously precise.

jason black

Nice touch with the circular brushed finish around the dials

Tom Wazny

Thank you mate :)

Clickspring

i really can't wait to see the finished piece... great work as always happy to be a patreon :D

Hi Dirk, its called Monotype Corsiva <a href="https://www.wfonts.com/font/monotype-corsiva" rel="nofollow noopener" target="_blank">https://www.wfonts.com/font/monotype-corsiva</a> and the font for the month names is Century Gothic. The sizes vary across the artwork - Cities 13.3, days 16, numbers 14.4 and months 6.3 - Cheers :)

Clickspring

Thanks Chris for the beautiful movie. Can you tell me which font and size you use for the dials. Thank you.

Dirk van Swinderen

Ha ha! Cheers mate :)

Clickspring

Ahahaha... black plastic bucket... I swear it looked like a paint can because of the perspective and shiny surfaces. Well, don't I feel like a dickhead. :D Comment edited, to hide my shame + avoid unnecessarily scaring people. Do me a favour and put a bit of tape on those BP connectors though eh? I'll sleep happier. ;)

Chris Talbot

My understanding is that its a copper based reaction, a bit more detail on the chemistry here: <a href="http://www.philamuseum.org/booklets/7_44_85_1.html?page=1" rel="nofollow noopener" target="_blank">http://www.philamuseum.org/booklets/7_44_85_1.html?page=1</a> -Cheers :)

Clickspring

Cheers mate :) re the UV box, it is all plastic (PVC bucket), each bulb fitting hot glued underneath - no metal at all

Clickspring

Beautiful mate, just beautiful. As you said in the intro, the fine finish of these visible components makes all the difference, regardless of how much precision has gone into producing the rest of the mechanism... the etched-and-waxed dial faces look amazing, and the silvering effect is so cool! Little tricks like how to get a circular grain on the dial faces are worth their weight in brass. Very excited to see it all come together.

Chris Talbot

That silvering powder seems pretty nifty and adds a really nice effect; does it work on other metallic substrates or is it a brass-only reaction?

Martin Anderson

Wow.

Peter Laws

Thank you John, very much appreciate your kind words :)

Clickspring

Thank you mate :)

Clickspring

Cheer mate :)

Clickspring

Chris, I’m running out of ways to say it! Wow! :-0. I really appreciate the exacting detail you put into everything you do. Even the smallest piece. Because of a condition I have, I’m loosing my fine motor skills so watching you do these incredible feats is mind blowing! You sir are a true craftsman, and I feel privileged to be able to watch you create these works of art. Thank you sir! Btw. Great idea putting the affiliate links on the description here, very helpful for anyone working on similar projects.

Your artistry blurs the line between skill and magic. Amazing.

Leonard Solomon

These videos are extremely satisfying to watch.

Glebs

Terrific to hear that mate :) Yes an oil based enamel paint works really well as a mask for blue, silvering etc several coats, esp on sharp corners and edges.

Clickspring

Chris, do you know if that gun blue maskable, or does it tend to get under the mask? I was thinking a blued/silvered/bare brass pattern could be quite striking for some applications. As always, amazing stuff! I have a retired machinist friend who I shared your Antikythera videos with. Very different than what he spent his career making (aircraft parts). He binge-watched them all. :)

Conrad Teves

Thank you Peter :)

Clickspring

Thank you mate, I very much appreciate that support :)

Clickspring

Thus far I keep it and store for future use, topping up with fresh as the level drops - Cheers :)

Clickspring

Its such an enjoyable process putting it on too - its like magic when that finishing powder does its thing :)

Clickspring

Very grateful for your support mate, thank you :)

Clickspring

Thank you mate :)

Clickspring

Ha ha! Terrific to hear that mate :)

Clickspring

Cheers Richard :)

I still remember when I tuned in to see how amateurs beat professionals turning metals. You're not fooling me anymore - you are not only a professional but you're showing your peers how it's done. I'm amazed at how you just manually file perfect squares etc and do minute details using very basic tools.

Peter Larsen

You make consistently the visually most pleasing videos I know of. I am really happy that I can support your creations, even if it's just a little.

Another great video, Chris. Having not done something like myself, I was wondering what you do with your waste fluids from etching?

Eric Logan

Sooo close to being done! Awesome work as always! Never heard of silvering powder before, had to go look up what it is. To my surprise, its silver chloride which means its actually leaving a layer of silver. I was not expecting it to be silver but it is and that explains why its so shiny. Cool!

Clifton Ballad

Your work makes me proud to be a patreon. Love it!

Giovanni Viscardi

Amazing

Travis Brown

Absolutely brilliant! Can't wait to watch the whole series again after it's completion ;)

Stefan

Always in awe.... Looking forward to the final video.

Richard Thompson

Ha ha! Thank you mate :) Definitely on the home stretch for the BSC, but still a long way to travel on the AM. Next Patron series will be a lot of fun :)

Clickspring

Thank you mate - 800 is my fave, gives a lovely grain :)

Clickspring

Fantastic - always learn a great deal from your videos - thank you. Now that you are nearly finished with the Byzantine sundial and the Antikythera mechanism, I look forward to seeing what next - A well deserved holiday I hope :-)

Phil Sydor

Another stunning video Chris. They're a joy to watch :) What's your go to sandpaper grit?

Tim bennett

So pleased you enjoyed it mate :)

Cheers Glen :)

Clickspring

Thank you mate :)

Clickspring

Thank you mate! The original was of a low zinc brass, hand engraved in the typical Greek script of the day - Cheers :)

Clickspring

Yes always glove up where appropriate - Cheers :)

Clickspring

Absolutely stunning as usual. I laughed with joy when I saw the circular-grained dials at 10:20

PeetieGonzalez

amazing

Brilliant work - as usual. Just a safety note though - the chemicals you are using, especially the Ferric chloride are very strong. You were wearing gloves using the etchant but not for the silvering or gun blue. I couldn't see the labels well enough to see what compounds they are. Many gun blues are very toxic indeed. As a lab chemist I am always aware of chemical hazards so, people, please make sure that you have read and understood the safety info that will have come with your chemicals and do NOT consider this info just a rear-end covering exercise by the suppliers.

Jeff Armstrong

Looking good 👌 so if this is the second last video whats the next can off the rank for the Patreon series? Give us a clue

Iain Deas

Beautiful work, Chris.

Glen Ralph

outstanding as always Chris, thanks again

daniel poole

Wonderful finishing! So 'dial wax' is a thing? What evidence remains on the pieces pulled out of the sea of markings? Was etching widespread 2000 years ago or would they have engraved the bronze? Had you chosen bronze as a metal would those chemicals you used on the brass been appropriate? Absolutely stunning work Chris!

Gregor Shapiro

Cheers Alex :)

Clickspring

Thank you mate :)

Clickspring

Beautiful work as always Chris

Derek McAllan

Not at all mate, there are no silly questions :)

Clickspring

Sorry, I feel like a real ditz Ralph

Ralph McCoy

The precision. The craftsmanship. Really cool to see the etching process. Incredible, Chris.

Alex Dragani

Terrific to hear that Chris :)

Clickspring

Thank you mate :)

Clickspring

Cheers mate :)

Clickspring

Both sides must be clean, not explicitly covered in the video - Cheers :)

Clickspring

Wow. I wondered how you were going to do the lettering. It's like industrial strength circuit board etching on steroids. Very, very nice

Michael Lloyd

Fantastic end to my day watching this Chris. Thank you sir.

Chris Muncy

Ha ha! Cheers mate :)

Clickspring

Print quality from a pro machine is essential. Even a slight fuzziness from a good laser printer will show up in the etch quality. If there's one thing I'd like to be the main takeout from this vid, its that there can be absolutely no corner cutting with regard to setting up the artwork for etching. Any doubts whatsoever, pull the pin and get it right - Cheers :)

Clickspring

A new Clickspring video! You just made my day!

Derek Meisenhelder

Chris, when cleaning the surface that is to be etched, no prep is done to the other side even though you are only etching one side. So what about contaminates coming from the side that in not prepped ,cleaned ?? This has been quite a journey, but well worth it. Well done Cris. Ralph

Ralph McCoy

The next episode cannot come fast enough!... chop chop! :)

Ha ha! Terrific :)

Clickspring

My immediate thoughts are. Why a professional print shop? You have demonstrated an amazingly steady hand before. Wouldnt tracing over lines with a crisp sharpie would yield the same result? I've seen this demonstrated on tests to defeat fingerprint scanners before. Maybe I'm just cheap?

Well I was going to go to sleep. But that can wait.
