fascinating stuff...Thank you. The old-timers were truly brilliant.

You are lucky to be living in London finding great watchmaker tools machines etc. We live in the USA and over the past 2 decades we really amassed what could be had only what we needed to actually make watch parts however these days we cannot get deals anymore in our opinion. We love you videos though they do come and go so we hope you will be back. Your channel was one of the channels that drove us to begin sharing our watchmaker machines and tools just so you know.

I can really appreciate your sentimental attachment to your collection. You must love what you do.

Hi there mate,good video. Don't worry about the sketchy comment,think it was a bit harsh. Wanted to let you know about one of my favourite ways of cutting or restoring small thread sizes. I use a tool called a thread plate where a series of threads are on the same flat plate with cutting edges from drilled holes. The screw is screwed into the correct hole in the plate to form the thread. Works very well and easy to cut thread straight.

Really enjoying your videos, great to go old school instead of 5 axis, interestingly one of my first lessons as a apprentice toolmaker many years ago was that a stick of inches was called a rule not a ruler.

I'm attending watch and clock making school and my instructor is a great collector of vintage horological tools. He has thousands of them. I sent him a link to J. Malcolm Wild. Thanks for the great video.

I'd imagine that large depthing tool costs substantially north of 1000 GBP. And the maker is the clockmaker to the queen.

Adam Booth, a man modest in everything but proportion.

Rambling is good, as it's all new stuff to me. Thanks for your time and effort putting this stuff out there for us. 8)

Many many thanks for the wonderful video and so interesting and at the moment I'm making my own clock depthing tool for use in my workshop as sometimes I encounter movements where the previous repairer in attempting to re bush got the new bushings off centre. Jim from AUSTRALIA.

I'm a retired UK police officer, although I served as an engineering apprentice in Leeds prior to this (thus my interest in precision engineering). When I joined the police service in 1972 I was issued with a staff (or 'truncheon') made from Lignum Vitae. Many British police forces used softer stuff, even as soft as spruce but West Yorkshire Constabulary always issued staves turned from Lignum Vitae. Although my staff was never 'drawn in anger' or had to be used for my self protection (times were different, then), I had a Labrador retriever bitch during my early years as a Constable and several times she tried to chew my staff, but for all her efforts, there were only a very few surface scuffs, although I've seen her destroy pieces of spruce in minutes. When we went over to the telescopic steel ASP baton in the 90s, I got to keep my old staff and now in my mid-60s still retain it as a memento. In the marine world, Lignum Vitae was not only used in 'block and tackle' work, but also as the bearing surface for a ship's main propeller screw shafts. A very interesting video (and series). Please keep up the good work.

Thank you so much for sharing you knowledge with us. I hear the reverence you have for your work and tools. It's one thing to have the skill and knowledge , but quite another to be able to and willing to share them with others, without sounding pompous. I'm looking forward to seeing your other videos. I loved the precision tools and your precise language. It goes hand n hand. Lignum Vitaes are also used for quality mallet heads. Try a piece of iron wood. I believe it will also sink. Thanks again.

Some very nicely made tools.

These are amazing, old technology tools.

Very interesting video. I am not a watch maker, but learned a lot from it. Cheers.

Thanks, Rob - well, horology is micro-engineering, and so there is a lot of tandem thinking going on with turners and other metal-cutting obsessives...

The ruler was probably used to open locks in cars.

oooh nice.. i have some of those red velum boxes. well worth the money spent on them. thanks for sharing!

I only now discovered your channel and find it fascinating. I do hope that you continue to post new videos. Perhaps a shop tour? Also, could you provide a link to an image of a proper horological screwdriver?

A very entertaining presentation, thanks.

Lovely and interesting thank you so much

The Bulova accutron is also made with a open face called the accutron spaceview !I got one, its a 1974 Bulova accutron spaceview big chapterring

OMG ..You have a Sector! I want!

Hi just watched your video , just of interest JMW only made 7 of his contrate depthing tool , I’ve 1 David Lindow has another and I know of another in U.K. who is also a Wahli multi lathe owner ! My mate Dave in Gloucester has mor pinion wire if you are after some , I’ve also got a 17c Wickes Tweezer as in Plombs book could be tempted to sell .

Thanks. Excellent advice. Perhaps you could point me to practical advice on using a depthing tool. I have been watching Open Clock Club lesson 43. Great importance was given to depthing before bushing. How is this done in practice with a depthing tool? I have bushed a number of clocks and I am worried I got it wrong without depthing first. Open Clock Club is very good but I find it annoying at times when they leave you a bit in mid air.

At a local auction I bought some horological items. The problem was I had to buy box after box because the auctioneer had put a piece or two in each box. So the bits I got where not particularly cheap. I have some items on ebay at the moment.

I've bought Pinion wire or rod new from McMaster Carr in the US

Were lucky to find a garage sale in this neck of the woods, but I'll keep My eyes open.

Lignum Vitae is a dense wood with high oil contents in it. John Harrison the famous watchmaker in 1730 used it as bearings for his church clocks because of the lubrication qualities and some of his clocks are still working. In ships the wood was used for propeller shaft bearings in the intermediate bearings and also the thrust bearings. A story goes that "Legno Santo" is another hard heavy wood which was the wood used in Christ's cross. Legno Santo meaning, Saintly or holy wood, was used for bollards in boats where it resisted the heavy forces and the effect of the rope spinning around the bollard as the boat was arrested to a stop. It all has to do with the oils in woods related to the functions they are asked to perform. Wood was always a versatile material.

It is STILL used in marine shaft bearings. The main screw of every American warship is beared in lignum vitae. Even nuclear submarines use it.

well...i have to say..nice video man nice...

great vid

Hi kosmos, Out of curiosity, for depthing, Is it not possible to just calculate the center distances if you knew the gear count and module and then scribe it using a compass? (Pp thorton has a formula for it, as well as the theory of horlogy) Im sure it works well but wouldn't you need to worry about the runners being perfextly parallel and perpendicular? I was thinking about looking for a watch sized depthing tool but i can only find old ones in poor condition. Are the depthing tools absolutely necessary for modern watchmaking? Or is it just used for restoration work? Thanks.

found a old alma cleaning machine under a bench from a woodworker i asked him if i could buy it and the only thing he said was if you want that old thing take it away from me its heavy old and a pain in my ... i bought him a bottle of whisky

Utilise the Trumpet Runner sir! (Then again, in this instance that may not be much better.)

I recently picked up a watchmaker's tool, but don't know what it is? I am a newbie, but have been acquiring tools to be able to work on PWs, but have not run across this tool on ebay or any web site. Is there a way to post a tool pic. for you to have a look?

how do you make a gear? what tool do you use is there like a punch?

Good Day! I just discovered your channel this afternoon, and I'm working my way through your catalog of videos! Well done, I must say! I am also a Clock/Watchmaker. I apprenticed under my Grandfather. While it's not my full time employment (I'm a railroader by day) I do a fair business here in NJ. Whom was that instrument maker in Sheffield? The audio was a bit rough at I couldn't make it out. I'm very interested in doing business with him. There aren't any instrument makers here in the States. Well, not good one's anyhow. Cheers! JMM

Kosmos Horology THANK YOU!!!

hi kosmo i am a retired woodworker because of wood dust problems , i,m embarking on a new hobby of model engineering and hoping to make a clock when i think i can handle it.i love watching your videos,can you tell me if you know wherei can get machine files for my excel die filer . or of anyone who has adapted files to fit cheers john

Very interesting I was surprised that some people solider and others used thread lock as a glue. I would of done it another way by using splines or bolting/ screwing them together but there agin im not a watch maker

Lignum vitae

Hi Kosmos, What exactly is your position within Horology as your knowledge seems very sketchy. I was taught at a technical school for instrument making and Horology in central London in 1954. 12 BA screws were huge and 16BA was often the norm. Your tooling while interesting are brand new whereas an interest in the field of horology would normally involve collecting only the antique tooling. Most of the tooling you have bought, we in my day would have made ourselves , you just didn't buy because the reative costs were huge, and the only way to get the correct tooling was to make it . My interest in precision engineering has persisted over more than 60 years and the modern field of CNC machines can out perform most if not all the old watchmaking skills, so although the art of watchmaking is dying it has in fact been superseded by CNC. Your mention of ABOM79 made me smile because he has called 1/8" milling cutters as very small whereas I have used milling cutters of 1mm dia and drills of under 0.010". It was not unusual to make drills below 0.010" by using hard wire and fabricate what was known a spade drills so watching ABOM79 makes my eyes boggle at the sheer size and quality of his work. The man is a metal working Master. Regards to all MoK

Hi Mo, your comments made me smile. Sorry you think that my knowledge of horology is sketchy, I can assure you that it is not. Certainly 12BA screws *are* small; I did not say that they are the smallest, but by any account, they are very small, and these days I would challenge anyone to readily point me to a supplier of 16BA taps and dies. On the other hand, I was recently called upon to drill out two broken gold balance screws that a ham-fisted watchmaker had broken off in the rim of a Patek balance (pre-Gyromax, you understand). No problem, I used my 1980s precision drilling machine with some 1920s spade bits of 0.15mm diameter. I then cleaned up the threaded holes with Swiss taps (I forget if the threads were 0.2 or 0.3). About CNC, certainly it is useful in many realms, but even today, the mass production of Swiss mechanical watches is largely done on "traditional" industrial equipment like blanking presses. A lot of turning is done on numerically-controlled sliding-head lathes, but it is not all CNC by any stretch. Making watch plates by 5-axis milling or wire erosion is unbelievably slow, and only suitable for production numbers up to a couple of thousand watches per year. About Abom and Tom Lipton & co, I agree, they would balk at the sizes of tooling we consider normal. I have learned so much though, and I will regularly push my "big" Myford 254 *much harder than I used to think possible, after watching what can be done. When I'm roughing out parts, unless the chips are blue, the job isn't going well! Maybe I will publish a few videos about watchmaking using antique tools from my collection. Subscribe and be the first to know!

Very interesting video but you do the same mistake as many many other "youtubers". When demonstrating an object or anything that fits in you hand, KEEP IT STILL!! Don´t jerk it around or joggle with it. Very annoying!
