Constructing A Byzantine Sundial-Calendar - Part 1 (Making The Cutters))
Added 2017-02-02 00:12:47 +0000 UTCHey Folks,
Making your own cutters is a valuable trick to have up your sleeve. So in this episode I go through one method in detail, and also provide a handy calculator that you can use to crunch the numbers.
Download the calculator and learn about the other methods from the "Tools, Glorious Tools" gear cutter series: https://youtu.be/8-eAhLGmsNQ
If you'd prefer to buy the commercial cutters for this project, you can purchase them directly from PP Thornton at their website: http://ppthornton.com/
Required cutters for the BSC build are:
1 x 0.85M Wheel Cutter
1 x 0.85M 7 Leaf pinion Cutter
1 x 0.85M 10 Leaf pinion Cutter
1 x 0.85M 12 Leaf pinion Cutter
Cheers,
Chris.

Hey Lucas, yes I think M0.2 will be too fragile for this sort of cutter. Best to go for a more robust design. A very similar approach can be taken to make a full profile flycutter (or even a multi tooth cutter) and I will be covering that in a future project - If you can't wait, recommend this book for some terrific gear cutter techniques, and general gear knowledge: "Gears and Gear Cutting", Ivan Law: <a href="http://amzn.to/2FKmaUI" rel="nofollow noopener" target="_blank">http://amzn.to/2FKmaUI</a> Cheers mate :)

2017-07-14 20:49:40 +0000 UTCI love the Idea of making a few of these because I need to make a gear using a M0.2 cutter but I am having a hard time finding one. But do you think these will be effective at that size? I'm afraid it will be too delicate at this small size. Any thoughts? Thanks!

2017-05-02 20:36:28 +0000 UTCThis video is what got me here! Very nice approach. There is another way to do this that will give you a constant profile cutter. Approximate (or calculate) the diameter for the tooth profile and use a small endmill that corresponds to it. You can then clamp a square tool steel blank in a vise on a mill and use hand wheels or a DRO to get your spacing. The depth of cut on the sides will be half the tooth thickness and the axial cut will be the tooth height. The angle in which you set up your tool blank in the vise will be the cutter relief. Then it's just a matter of cleaning up your cuts and sharpening the bit flat on a stone! It can be sharpened over and over without losing it's shape. It takes a mill and an extensive set of endmills. But considering the price of a Thornton cutter you might be inclined to get a dedicated endmill for your project. Thanks for great videos!

2017-02-07 19:54:13 +0000 UTCHey Mike, selecting a lathe is a big step, I have written a little article here that might help: <a href="http://www.clickspringprojects.com/blog/which-lathe-should-i-buy" rel="nofollow noopener" target="_blank">http://www.clickspringprojects.com/blog/which-lathe-should-i-buy</a> Speeds and feeds are something that you will very quickly learn by doing once you get your lathe. Start out with the charts, but before long you'll be able to eyeball chip color, and use your ears to tell if the cutter is happy, and adjust accordingly. And of course brass is a dream - it makes everyone look good at any speed!! I shoot with a Panasonic HC X920, and edit with Adobe Premiere. Footage qty varies with the task - It works out to be about 5 to 10 hours of plan/shoot/edit work per minute of screen time. I shoot what's being made, and usually I'm fortunate that there is more than one of each part required, which gives me one to plan the cuts and shots, and then 2,3,4 etc to actually shoot and get the extra angles and cutaway shots. If its only one part, then I take my time and really plan out the shot - I'm only going to get one chance!! To date I have mostly just shot the action and then written the VO, but the Antikythera and Sundial-Calendar projects are a lot more narrative driven, so I am finding that the dialogue for those must come first. Cheers mate :)

2017-02-04 19:16:08 +0000 UTCAwesome Chris! A few questions (probably too many)(but...) I am an editor / animator by day and wanna be maker by night. I have built my CNC (kit, with many personal mods) and have that world working pretty well, but have been eyeballing lathes ever since. It's pretty much your fault, but I thank you for it. Knowing what a beginner will go through and want to start building, is a 7 x 14 enough to get going and have enough room to learn and grow. I see many which I could get into for under 1K (US). While this might not be a lot to some, it's an ask for me. So I want to make sure. I know you speed some of the work up as it would take far too long to present at full length, but in other videos you have taken a cut at normal speed, then sped up the video. This is helpful for getting an idea of feed. Could I ask you to mention what use for RPMs. Or... is it relative to the given situation (machine / material) and wouldn't translate? As an editor, I am curious 1. what camera are you shooting with and software you are editing with. 2. How many hours of footage do you usually start with? 3. Do you edit first, then write your VO, or do you start with the VO and then edit to that? The metal work and the instruction are top notch, but in addition, you do an excellent job in the presentation. I know how much time set up and shooting can take, and machining isn't necessarily fast either way. So... yeah. Thanks.

2017-02-04 01:03:34 +0000 UTCAs always I love your work and you've inspired me to begin my journey into metal work. I would like to concentrate on building hand tools for woodworking and movements for clocks. So I need some advice on purchasing a small bench lathe. I do plan on doing majority of the work by hand as I do in woodworking, it's a traditional approach I don't wish to depart from. I would prefer to work with an antique foot powered metal working lathe but I'm sure they are too difficult to find and would be very expensive. So what lathe do you recommend ? What tools will I need? Where can I find brass and O1 stool steel? I live on the Gold Coast so it would be nice to save on shipping to pick them up myself but if not anywhere in Oz would be ok.

2017-02-02 11:11:41 +0000 UTCSo pleased to hear that Paul! There are a few multi tooth cutter designs that I am keen to try out for cutting steel pinions, I will work it into a future project at some point. Generally the stock used for pinions is the source of the problem - its a real pain to work because of its higher carbon content (required for the heat treating). Even cutting pinions with top grade HSS cutters gives me the willies - its such an unattractive combination of a large cutting edge, poor chip clearance, and tough material that any cutter will struggle and need close management, no matter what its made of. Yes spot on for the radius gauge - just drill a hole and then file or mill off one side. Definitely accurate enough, the addendum of a clock wheel tooth is surprisingly forgiving. Yes the Sherline would be perfect - in fact I very nearly did all of the shooting for this video on the Sherline, but it tends to be harder to get good lighting on it where I use it, so I went with the SC4 instead. The Sherline is superbly accurate for small stuff like this. I will show more of the cutters being used in the next episode, when I cut all of the wheels and pinions for the project. Cheers mate :)
Clickspring
2017-02-02 10:31:58 +0000 UTCHoly crap, that is a good video. The cost of cutters has been on my list of excuses to not trying to make gears on the lathe, don't want to spend all that money and ruin it on the first try. I finally see how you get an angle with the dial indicator. I have looked at the references you cited and they made little sense to me. Your explanation makes it all very understandable. Is there a home shop solution to make a cutter that would work for steal pinions? How did you make the radius gauge for the lathe cutter, I'm thinking just drilling a hole and cutting in half but is that accurate enough when dealing with hundredth of a milimeter? Could you have made the cutter on your small Sherline as currently this is all I have? Lastly it was nice to hear pounds £ being used. Just truly amazing work. If I am allowed one complaint, I could have watched more of it :)
