The pivot and inside shoulder bearing for the Saros Pointer Assembly - There were several other adjacent components constraining the size, shape and design of this little bearing. This was the ancient solution to permit not only clearance from those other components, but also to provide vertical stability and acceptable friction: (Short Video)

The new Weiss lathe (WM250VF) has been sitting idle in the shop without being properly installed for many months due the the AM and BSC projects, but I finally got around to leveling it and taking first cuts over the last few days. First impressions so far: Its a high quality machine, with not a whole lot to complain about. I'll cover it detail in the next TGT, but I want to push it a bit harder over a few weeks to make sure I don't miss anything before discussing. So I will do a bit more on that TGT today, and then back on the AM from tomorrow, working on both over the next few weeks.

I've had a blast writing and narrating this latest vid, and I think its going to kick off a fun new series - the first episode is on its way to you now, and it should land in a few hours.

Putting in a safe edge as part of the new shop skills video series - more editing today
-----------------------------
(Update March 17th, 6:15pm AEST)
I started shooting today for the new series of shop skills vids - I've decided to kick it all off with my fave tool: hand files
-----------------------------
(Update March 13th, 7:15pm AEST)
The pivot supporting structure for this next part of the mechanism (Saros train) is most unconventional by modern standards - this is part of the small bearing insert that will hold the Saros Pointer assembly. A thin flange will slip over the smaller square boss, and then the whole thing will be riveted into the main plate, much like the main bearing.
-----------------------------
(Update March 8th, 6:15pm AEST)
The test fit is good - all ready for permanent riveting.
-----------------------------
(Update March 7th, 5:15pm AEST)
A square hole for the F assembly hub - I do wonder who got the job of filing these on the original...

Hey Matt, yes brass is crazy expensive - I get most of the larger round stock from my local scrap metal depot - Its still expensive tho!
Clickspring
2018-04-05 20:18:11 +0000 UTCHey Chris, caught myself re-watching your clock series -- procrastinating from uni work like usual, and I had a question... That counter weight you formed from a large piece of brass round stock - that would have cost a fortune, how much was it and where'd you get it from?
Matthew Thomas
2018-04-05 09:07:43 +0000 UTCYeah, having just bought one of those myself (and the BF-20 milling head) it is *almost* identical save a few features, so probably a slightly varied model out of the same factory.
Jrandom Bob
2018-04-03 23:28:15 +0000 UTCVertex allegedly makes one (cat. no. V-407), but I haven't seen them for sale anywhere.

2018-04-01 08:04:15 +0000 UTCSo far its encouraging, but I really want to spend a good couple of days on investigating the it thoroughly before commenting - will let you know :)

2018-04-01 08:02:15 +0000 UTClathe looks good, have fun getting a 4mt to er32 collet chuck for the headstock, i found one from CTC tools.
Iain Deas
2018-03-31 23:33:09 +0000 UTCi was thinking the same as i've got the optimum 2506, the optimum is a weiss rebadged im pretty sure?
Iain Deas
2018-03-31 23:31:54 +0000 UTCThat Weiss looks like it identical to the Optimum-branded one I'm considering buying, so I'm very much looking forward to your video on it. How's the tailstock?
Damien Miller
2018-03-30 05:38:24 +0000 UTCWell thank you for replying and trying to help. Oh i LOVED the skeleton clock you made mostly from brass. It really helped me pass tge time while i was in pt for a dislocation a couple years ago. Also i can't wait for the day that i can use the prints for the little hand vice. I took a manual machining class last year and LOVED it. Only wished I could have used that time to make that machine.

2018-03-22 04:20:16 +0000 UTCHmmm... Must be something my phone is doing then. Like i see where you can click the attachment and download, but below there is that number of blank picture frames like if a picture link was broken or something. I'd send you a screen shot if I could
Justin Densmore
2018-03-22 04:08:37 +0000 UTCI'm not sure what it would be mate - I don't have any thumbnails at all when I view that part of the post in a browser, I see only the links.
Clickspring
2018-03-22 02:09:38 +0000 UTCLike on the March 18th update, you have 5 attachments. And below are the small blank picture's. So if there are viewable pictures, i have to download the link
Justin Densmore
2018-03-21 13:19:44 +0000 UTCSo you know the pictures of your projects that are at the bottom of the description and updates you make that can be downloaded and enlarged. Well they are on average just a broken/blank image of a picture frame. I'd send you a screen shot if possible.

John Lancashire
2018-03-16 22:21:26 +0000 UTCHey John, the pointers are set upon assembly - Cheers :)
Clickspring
2018-03-16 21:55:53 +0000 UTCGreat. Looks like you're building the Saros gears. What's your strategy for calibrating the machine once it's finished? Obviously you need to be able to move all the pointers to a specific start position on a specific date and synchronise that with the position of the lunar epicycle gearing on E. The only way to do that is to allow the pointers to be adjusted on their axles, but they can't be too slack because you need the axle to push the long pointers around the spiral. Remember - you're not allowed to use grubscrews!
John Lancashire
2018-03-16 21:18:04 +0000 UTCThank you mate, terrific to have you on board :)
Clickspring
2018-03-16 20:56:33 +0000 UTCGreat project by the way - it looks beautiful,
John Lancashire
2018-03-16 20:52:08 +0000 UTCHey John, yes I've corresponded with both - Cheers :)
Clickspring
2018-03-16 20:48:33 +0000 UTCHi Chris. Have you been in touch with Tony Freeth or Michael Wright about the design?
John Lancashire
2018-03-16 18:32:04 +0000 UTCHey Tom, there is still much ground to cover that will influence the final result, but I'll have a good idea of that cost in a modern context by the end of the project.
Clickspring
2018-03-16 05:38:28 +0000 UTCThinking about who had to file all the square holes got me thinking, do you have an estimate on how many skilled and unskilled hours it would take for a shop to produce one of these devices purely by hand? I'm wondering if you could estimate a 'cost' based on the parts and labor. I'm also wondering about this cost in a modern context. e.g. was the mechanism like buying a jet plane, a Ferrari, or a Lexus?

Clickspring
2018-03-09 20:51:43 +0000 UTCFunny, I have just assembled a French clock with a lock plate strike, which has very much the same type of problem with only 4 wheels, and was thinking the same thing about Chris' challenge - could always do the setup and then engrave the plates (LOL)
David Paterson
2018-03-09 00:38:32 +0000 UTCNoice, eh as they say in your parts. Impressive fitting as always Chris.
David Paterson
2018-03-09 00:36:20 +0000 UTCCan I suggest a potential topic for your tgt segment? I think it would be really good to have one on the tools required for marking up (spring dividers, dogleg calipers and whatnot) and the basics of their operation. You make it look so effortless, but the amount of skill required to do it properly is sometimes understated. You have such a fantastic educational approach to your videography that it would be remiss not preserve it on the internet.
Adam Seymour
2018-03-08 22:55:08 +0000 UTCIts funny... as i read your response, in my head i read it with an Australian accent :)
Kirk Jensen
2018-03-08 21:08:37 +0000 UTCYes the data is easily available today for setup - not quite good to go 'forever' once set tho. The ratios are extremely good in some respects, but not perfect. This is something I'm going to cover in detail towards the end of the series - Cheers :)
Clickspring
2018-03-08 20:50:25 +0000 UTCIt will be very interesting to me to see how the entire gear train is "timed" in the end. I guess you will consult an astrological expert to set the dials and indicators correctly the first time? after that its good to go forever?
Kirk Jensen

2018-03-06 02:43:22 +0000 UTCI am an enthusiast of the Antikythera machine and your amazing reconstruction project because Derek de Solla Price was a colleague of my father's. I met him in Yugoslavia as a child, way back when; all I can remember is that he had an amazing wristwatch, with dials for the sun and the moon. He was seriously into that stuff! Best wishes in all your work. Bob
