Anybody print the barrel closer that's floating around the internet?

Specifically talking about this guy. A friend got a very expensive resin printer, I know NOTHING about this but i am a 3d modeler so i will be designing a couple tools which i'll post here in the future including a double sided tool for setting seiko diashock springs. Anyways he printed this out for me and he's not sure why but it doesn't appear to have come out the correct size and can't actually close a barrel. The diameter of the cap on the one he printed is .975 inches. Does anybody have the bergeon barrel closer this is a copy of handy and can measure the diameter of the cap so we can figure out what we have to scale this thing to to get it work?

@Birbdad

hopefully this will help

top part

outside diameter 25mm

inside diameter 22mm

arbour hole 3mm

overall height 14.25mm

depth of central cavity 9.75mm

 

base part

core outside diameter 21.5mm

base outside diameter 25mm

base height 4mm

overall height 16.5mm

arbour hole 3mm

top of core is convex, centre is approximately 1.3mm lower than overall height measured to the edge of the top of the core

Sorry, autocorrect gave me convex, it should of course be concave

Interesting. So it is the correct size, it just is a crap tool and doesn't work haha. Not yours, the one i had printed.

The inside surface of the upper part must be domed to ensure pressure on the outer edge of the barrel lid.

Yeah this one does not have that that i can see.

so I'm confused the tool is crap or your printing is crap or your printing of the tool is crap or something else?

Dimensions

Ok this is amazing. This will make things so much easier!

I think this guys design is crap haha. This could open a pocket watch barrel but it's not even close to being able to open a normal watch barrel. When i put the barrel in and put the top on there's so much space between the flatceiling of the top and the cavity in the bottom the barrel just rattles around in the thing. THe printing itself came out perfect.

So messing aroudn with redesigning it and looking at vids of the bergeon one, it appears the ceiling of the inside of the top part is flat. 

You're saying both sides are  domed/concave? It feels like the top surface should be flat since it feels like that's putting a lot of pressure on the teeth of the barrel. On this guys design the bottom part is domed but not the top.

I was being confused I would normally agree but is that really how the tool is supposed to be used? I normally don't use the tool can as I'm trying the close pocket watch barrels and they just won't fit in the one that we have at work. I was looking to see if I had dimensions anywhere because this is a school project they make it at school or can make it at school like the PDF that's attached.

But it brings up a problem I snipped out an image tool doesn't exactly work the way I thought it was supposed to work.

Then found a video shows using the tool.

wait wait wait @Birbdad. You trying to open or close the barrel? That item is for closing the barrel, there's no tool for opening it. That being said, why not just buy the closing tool? They're less than $10?

You can't open a Seiko barrel like the guys show on YT, you'll bend the top cover. You'll have to gently separate the two halves using a sharp knife or small sharp screwdriver. It takes practice to do that without marring the barrel.

You're on the ball today matey, beat me to it, i think Col just got opening for closing mixed up though.

Whut, i'm tryin to close it XD if i typed open that was a mistake.

And the bergeon tool is 40 bucks because of course it is. Where are you seeing this for 10? 

really my buddy wanted to test out his fancy new resin printer and this is free.

Mine it is the core of the base part that is concave on top

Yeah that's what i figured. It looks like whoever modeled this one made the concave part too deep and the side walls of the top part too long so the flat top of the top portion doesn't contact the barrel.

Lol Col . Knock 30 bucks off that and you have a bergeon one that doesn't have 30 bucks worth of Bergeon lettering spelling out the name Bergeon. 🙂

But the word bergeon is what makes it a REAL tool!

I have plans to model and 3d print a tool for setting diashock springs. I"m going to model the word bergeon into it so it works better.

Haha. If thats true then I'm having Bergeon tattooed on my forehead this weekend. 

I tattooed it elsewhere. The misses is pleased.

Hey this is great. Maybe it's not clear but is the 1mm the width of the hole for the arbor there or is that the depth of the concave in the top of the core?

As per the dimensions I posted the holes are 3mm, the depth of the concave surface on mine is approximately 1.3mm. Gary has posted his measurements and the depth of his concave surface measures to be 1mm

Yes, the hole through both pieces is 3mm. The depth of the concave was "estimated" to be 1mm since I don't really have an exact way to measure that. Based on the design I doubt there would be a functional difference between a depth of 1mm v. a depth of 1.3mm. I used to have a routine that would allow me to calculate the radius required to cut a diameter based on three points but I wasn't in the mood for trying to dig that out. Not sure how the 1.3mm was determined since there is no material at the center point of the depth.

Also, I didn't measure the ID of the upper piece as it will need to be 21.5mm plus whatever the nominal slip fit clearance needs to be. Again, if the top doesn't have an exact slip fit it will not impact the function of the design.

Hey Gary, it was an approximate measure as I could use the depth measurements using my calliper which gave me the depth with one part on the edge and the “stick” on the edge of the hole. Hence approximate.

Hi Tom,

Mine too but I laid a steel rule across the top and then used the extended end of my caliper but I just eye-balled it and figured 1mm was close enough for gov't work 🙂

    • If frank says these bombè jewels are for balances and similar pivots then they are used cupped side facing the pivot and then capped i assume. In Nicklesilver's reply i guess that cup can also be reversed and used as an oil reservoir leaving the shoulder riding on a less frictioned domed surface. 🤷‍♂️ Hence the use of them on wheels closer to the escapement that have less torque requiring efforts to reduce friction and are also uncapped.
    • Looks that way, if it had any amount of significant jewel count it would say so on the dial.    Looks that way, if it had any amount of significant jewel count it would say so on the dial.  Same answer as Mike regarding the dial, its often just a slapped on name of a retailer but i thought you were way above this understanding Pete ?
    • Light naptha is what you need to be looking for. The carbon to hydrogen ratio is high with heavy naptha, it doesn't evaporate as well as light naptha and is prone to leaving more residue. Try tom's suggestion of the mirror test.
    • Its a big item Michael and a lot that could go wrong with the process of getting it to its new location. I once helped install one of these units into a conservatory that i had built. It was big and bloody heavy and took six of us to get it in safely. If you have sliding doors and you need to remove the whole frame then that may or may not go well. But i would advise getting a professional in if you have little knowledge on the installation of them. The glazing of the doors could well be 6mm laminated glass which again will be heavy very heavy if the glazing units are big. The glass would also need to be set up and packed correctly to open the doors properly more so if they are unframed and the sliders are upvc. Seems a shame but if no one is biting and that may be due to having no warranty i guess the only takers might be someone that installs them for a living and knows how to repair. If its fibreglass just be careful, i sometimes have to cut fibreglass baths out and they are nasty to work with . Thick gloves are definitely recommended,  not fun picking out fibreglass spells two days later that have started to go septic. Good luck with it all matey.
    • I don’t know anything about this product, however assuming you have it if you put a drop on a mirror or piece of glass lying flat on a table and leave it to evaporate if it leaves any sort of residue it is not really suitable for watch part cleaning.   Tom
