2019-06-13 20:01:27 +0000 UTCKeep up the good work, Chris! My old class is still using your prints. I'm actually going to be a tool and die maker erdie July, all because you've inspired me! Love your material! Never give up!inspired

2019-06-13 03:56:17 +0000 UTCThere's no particular benefit over the nearest metric or fine imperial threads, and you can generally move to the nearest equivalent without much issue. But like you, when I was setting up the shop for clockmaking I purchased a tap and die set that covers the whole BA range so its what I tend to use now rather than buy more taps/dies. This book: (Amazon affiliate link: https://amzn.to/2Mf1MPn ) is brilliant. There is a set of conversion charts at the back for all thread standards, that I refer to at least once a day. Whatever set you go for, you will be able to convert a given project to your tap and die set with ease - Cheers :)
Clickspring
2019-05-29 00:53:53 +0000 UTCI notice you use BA screws, the clock i'm planning for uses them and i was planning to buy a tap die set. Is there a reason you choose to use them here?

2019-05-12 20:35:36 +0000 UTCHi Joshua, yes there are some buffering issues occasionally with Vimeo - try the direct video link for YT that is below the post text - Cheers :)
Clickspring
2019-05-12 20:23:42 +0000 UTCFor some reason since you've switched to Vimeo all your videos skip and stutter when I use Chromecast to send them to my tv. Never happened before 😣

Clayton Firth
2019-05-06 07:43:09 +0000 UTCThanks, I figured that was the answer but it wouldn't hurt to ask.

2019-05-04 23:25:45 +0000 UTCCheers mate :)
Clickspring
2019-05-04 07:42:20 +0000 UTCVery nice, Chris. Be good to finally see it in action in the next video. :-) One suggestion: tinning each end of the split ring before threading the smaller ring onto it might help further reduce heat colouring of the smaller ring by making the final soldering together of the ends of the split ring easier and faster. Cheers.
Sean Kirby
2019-05-04 07:28:23 +0000 UTCYeah, that was particularly stunning camera work, even by Chris's usual high standards. :-)

Jeffro
2019-05-04 04:02:51 +0000 UTCFantastic as always. Any chance of getting the Solidworks files? Thanks!
Ben Manthey
2019-05-04 03:37:43 +0000 UTCThanks for the answer! I really admire what you do. Taking the time not only to make these things and share them but also to answer questions about it is really inspirational.
Michael Fisher
2019-05-03 20:55:25 +0000 UTCHi Leo, water (generally as brine) gives a faster quench than oil, and so brings with it the slightly elevated risk of cracking, particularly for larger parts. Although for the steel used here (EN8) with a small screw, either quench medium would be ok. Definitely worth an OST, I will add it to the list - Cheers :)
Clickspring
2019-05-03 20:31:02 +0000 UTCHi Michael, I generally use Tix solder and flux (amazon links below) and I get the clock pins from Meadows and Passmore: <a href="http://m-p.co.uk" rel="nofollow noopener" target="_blank">http://m-p.co.uk</a> - Cheers :)
Clickspring
2019-05-03 20:23:06 +0000 UTCThank you John!
Clickspring
2019-05-03 20:20:17 +0000 UTCIs there a reason for quenching in oil instead of water? If so, the differences in various techniques might make for an interesting Old School Tips video... Also, is there a particular reason you decided not to blue the gnomon pin? Just wondering if it was a purely aesthetic choice or if there was some technical reason like wear on the part or something?
Leo G.
2019-05-03 06:05:11 +0000 UTCChris, I was just wondering what type/brand of solder and flux do you use? Also where do you get your tapered pins?
Michael Fisher

Greg Nixon

Clickspring
2019-05-02 01:50:54 +0000 UTCYes - the next video will cover the start to finish of a new (to me) process, as well as a few things about the mechanism design that I modified from the prototype - Cheers :)
Clickspring
2019-05-02 01:50:05 +0000 UTCTwo things that really help me are 1./ Use a light to illuminate the work from above, and then lightly cross grain the surface to catch the light. When working, watch what happens to that cross grain with each stroke, it will tell you right away if you're dropping the cut left or right. 2./ Align the work with the natural lines of the shop (walls, bench, floor etc) Its surprising how much the peripheral cues subliminally affect what you do with your hands - There is a bit more detail on this here: <a href="https://youtu.be/h4KaiG7CpSQ" rel="nofollow noopener" target="_blank">https://youtu.be/h4KaiG7CpSQ</a> - Cheers :)
Clickspring
2019-05-02 01:48:25 +0000 UTCChris I see you use roll or round solder, have you ever used ribbon solder ? It is very thin and can be cut so you can put it in the joint and well save you clean up This has been quite a journey well done
Ralph McCoy
2019-05-02 01:45:32 +0000 UTCI generally use a leaded free machining brass, and yes it will shoot off as a fine powder at certain speeds and depth of cut. One thing I do to avoid this is go for max depth cuts wherever possible, with a relatively slow rpm. Brass will cut well at just about any speed, but slow with a deep cut gives nice big chips that fall away that are much easier to manage - Cheers :)
Clickspring
2019-05-02 01:41:57 +0000 UTCYes its a chunk of pumice

Ralph McCoy
2019-05-02 01:32:51 +0000 UTCChris, when filing parts how do you keep from filing on an angle ??
Ralph McCoy
2019-05-02 01:31:44 +0000 UTCWhat alloy of brass do you use? You seem to get nice flaky chips from it, whereas the brass I have (mostly offcuts, maybe 385?) flies apart in an unholy powder that gets into everything...
Damien Miller
2019-05-02 01:30:51 +0000 UTCChris, when you are soldering what type of "rock" is that ?? pumice ??
