je hebt het prachtig daar kalle... mijn ogen uitgekeken toen ik bij je was ....

[@johnnyarsenault9124]

From a watch enthusiast: You have pretty much everything to do almost any watch parts! How do they do various watch hands & pallet forks , hair springs? The mysteries of these components! 😮

[@giovannibalsamo4753]

😊the sale operating for Watch 😅 great ‼️💯

[@robkoning6019]

I like the walk through even I have been there a few times.

[@edgeyt1]

Wow. I didn't know you were in such a serious way of business. All those wonderful machines can't be cheap or easy to come by.

[@afoot4silver800]

I want to go there! Former prototype, tool and die machinist and aircraft instrument repair tech, gunsmith. Best watch channel out there!

Hello people

[@windward2818]

Thank you for the shop tour. As you probably already know, there are many small machines (mechanical structures) beyond watches which must hold the tight tolerances you talk about in the video, mainly perhaps to a tolerance or +/- 3 Microns (Millionths of a Meter), in imperial units in the US the tolerance would be +/- 1/10,000 of an inch. However, virtually all of the new complex systems designs are all metric, with the one notable holdout being sheet metal (sold to the general public) gauges in inches. Here again, if you buy enough sheet metal you can get it in metric sizes like Boeing or Gulfstream Aircraft Companies. Some of the very small very tight tolerance machines for Aerospace and Defense can get to the +/- 3 Micro tolerance spec while at the same time being made from some exotic hard metals like Inconel which have impressive corrosion resistance. The challenges in making these small machines is in measuring the structures (parts) accurately given metals tend to change in size with temperature as I am sure you are aware. In the USA the design process for small machines is much like the processes in your workshop except for some notable differences which has to do with the way expensive fine tolerance machining work is done mainly by contract in the USA. The part is designed and simulated in Mechanical CAD, then machined (CNC), small gears can still be hobbed (hobbing) on a CNC latch, the parts are measured with a CMM for rough quality control and then optically compared for fine final checking, special custom made go no-go gauges are used when possible to speed final inspection. The CMM (Coordinate Measuring Machine) and optical comparator equipment are located in a temperature controlled room (the room has a high air flow rate where the air is scrubbed (filtered) and re-used) with double doors, where are parts are allowed to acclimate to the room temperature before measuring and only handled with tools. In some designs the thermal expansion of metals is used in such a way as to try and cancel the effects of the expansion of metals when it effects overall operation, like with the use of Inconel as compared to 316L SS as just one example. You can use different metals in different parts of the design to cancel thermal effects which lead to increases in friction or spatial errors impacting function, much like in a watch. Very hard material like Diamond and Synthetic Ruby (Seitz) have a very low rate of thermal expansion as compared to 316L SS. So basically the design process is done like this: The complete design (all parts either in house or from supplies) is based on 3-D CAD models or generically called Mechanical CAD (SolidWorks, parametric modelling software as just one example) and Artistic Design Surface 3D CAD (Rhino, like ornamental jewelry, surface based modelling software). The surface models are imported into SolidWorks to then fit them into an assembly, and / or analyzed by simulation, mechanical stress, fatigue, etc. All of the parts have an associated final model representation (for CNC export) along with a drawing or may be issued as MBD (Model Based Definition) file. MBD is only really necessary for very large customers (like Boeing) who require a specific format to fit into their design and approval process. If MBD is not used then every part has a drawing associated with it, which can be printed out as a popular size of ANSI Size D (on ARCH Size D paper), but is usually issued electronically as a PDF. The drawings adhere to ASME Y14.5 - 2018 GD&T standard, and the assemblies are subject to stack-up tolerance analysis which is also done in SolidWorks. The 3D models are used to make the parts, or as much as the part as possible before hand work on a CNC (like KERN or Schaublin, and custom modified versions of such for work holding (perhaps 25 blanks, depending on the machine)). The smaller lathes have automated round bar feed usually with twin work holding spindles, in a Mill-Turn configuration. For ornamental design many high end jewelers are experimenting with Laser engraving of high intensity on specialized metal surfaces (fine polish, heat treat, plating and then Laser engraving) to give some interesting patterns beyond traditional machining striping and swirling (flowering), which can be automated through a CNC laser engraver (usually one blank at a time). Some very interesting results can be obtaining which look hand engraved. I think the challenge is in finding the best metal surface treatment, but I am sure your workshop could find a good metal type and surface, or perhaps even automate the metal swirling with a CNC machine, much like what is done with stripping.

Wow My lifetime would not be enough to collect such a collection of excellent machines. Wow awsome!

[@todds2248]

Absolutely amazing collection of machines and tools!

Sorry I cannot be with you “live”. Hope you’ll enjoy the latest workshop update. Cya! Kalle

[@darksideka]

Hi Kalle Would you consider doing a before and after series of videos for some of the livestream projects that you're undertaking? Keep up the great work and sending prayers and support to You your family and for Dad.❤

Hello from scunthoroe

[@Niak38240]

You're talking about toys, you're wrong it's all treasures, the tools, the benches, the books even the armchair, and I really love the stand alone clock and it's sound, you inspired me a lot for my shop and my tool selection. And now I'm working on acquiring some talent... I can see you done a lot of work since last year. It's not who forget to remove the scope from Fat Bertha ! Lolll

Never boring, love the videos with machines and tools, great video as always.

[@henry4130]

I am so impressed on how clean and organized your shop is, how do you stay so organized?

[@WristwatchMedic1953]

Really interesting tour of the shop. Thank you

[@dbaider9467]

Lovely workshop man. The power of coffee... :) I did not see any fire extinguishers. Just a thought. Old tools can short out.

[@WardiTime]

Thanks Kalle, very interesting tour and just an awesome collection of specialist tools. You make us jealous but also inspired. Great.

[@rossjackson3670]

Thank you. Thank you. Thank you! What a brilliant tour and explanation of your chronoglide workshop. We (me) as subscriber(s) feel so privileged to be shown round. Your smile says it all. And yes, I was smiling all the way through. Plenty of 'ooohs' and 'aaaahs'. My bride even watched and said how good your tour was.

[@SQueme]

24:13 amazing tools, and amazing workshop / collectible the most interesting would be to show them in action ... either one at a time or on a full project (its not for a simple repair obviously 😉)

[@alaindrolet_atlt_2019]

Wow so interesting, it’s great and complete workshop. Congratulations for all what you are doing ! ✨👌 best regard Kalle !! 🙂

[@roobisk]

Really nice and clever layout. As a watchmaker who planing on building my own workshop this is pure inspiration! I have a similar set up with Schaublin 70 + 102 lathes and a Schaublin 12 milling machine to drill coordinates with help of the DRO. To stand the bigger lathes at an angle next to the wall looks really nice. I’ll probably do the same. Thanks for an amazing channel cheers from Sweden

[@anteneupitra]

the more einteresting is noone need mechanic watches nay more..:)

[@roobisk]

@@anteneupitra Need and desire is two different things. I’ll do it as a non commercial hobby just for myself to preserve the traditional watchmaking. Also it’s one of my biggest interest. :)

[@OrbiterElectronics]

Resin? Thanks Kalle.

[@joetallon4968]

Your equipment is amazing! It must be fun knowing how to use all of it!

[@johnnyarsenault9124]

If you have a chance to experiment with hollow micro-speres for sand-blasting 👌❤️👍, gives another type of finish. This medium was available thru 3-M at a time. The same stuff they use in reflective paint in road signalisation (yellow or white paint mixed with this h.m.s) , another finish is also given with quartz particules . 👍

[@adfpv1153]

Great tour Kalle thank you, thoughts are with you at this time too ❤

[@tomholloway7566]

Thanks Kalle, I wish I could get too one of your courses, sadly not to be

[@htchtc203]

Dear Kalle, thanks for tour. I am so glad I had chance to see your workshoo live. What is the relief machine next to the rose engine. What it is suppoused to use for?

[@SvenEugenots]

Fantastic collection of tools and machines! I was wondering if the Kronoglas machine is capable of grinding facetted crystals. Or do you have tips for recreating, or repolishing the 70's Seiko Hardlex facetted crystals?

[@artblend4278]

Amazing how you gathered all these machines!! maybe I'm wrong but I haven't seen a laser welding machine?🤔

[@soundmindtv2911]

Thank you so much for doing this tour! I'm so enthralled with each machine, and I'd really love to learn each one. Of course, 23:46 is the most indispensable machine in the whole place!

1mm = .03937” That’s a good estimate not exact. Very lovely machines, I love looking at them. I am a machinist here in USA but on a larger scale, just recently fell in love with watchmaking. Thanks for all you do!

[@beautgrainger147]

This isn't the only professional horological workshop I've seen (2 others in person), but looks better equipped by some margin.. though one did have a bunch of legendary toolroom machines. I'm kinda envious of the Deckel LK

[@watchrepairwithchris4346]

I enjoyed that tour, many thanks. What courses do you offer? Maybe I could visit before I am to old and fragile.

[@johnnyarsenault9124]

When you talk about pouring it in: epoxy or acrylic??? Silicon mould???

[@MrRoundel]

That lathe cabinet is gorgeous. What a great stable of machines! Great stuff. Thanks for the tour, Kalle. Reaching for "resin", by chance?
