hi guys, hoping for a little guidance.

 

i'm looking to polish up a few hardlux crystals and cases/bracelets in my collection.

 

and wondering what tools i should get to have a fairly complete set of them to do the typical work in this area.

 

so far, i've found this video

 

the other videos i've found are pretty bad on this topic.

and i've found these kits

http://www.ebay.com/itm/NEW-684-01Dremel-Cleaning-And-Polishing-Moto-Tool-Kit-20-Pc-NEW-/271227643126?hash=item3f266d64f6:g:tnIAAOxykVNRwusc

https://www.amazon.com/Dremel-684-01-20-Piece-Polish-Accessory/dp/B00005LEXV/ref=sr_1_10?ie=UTF8&qid=1485665200&sr=8-10&keywords=watch+polishing

is one of these kits suitable or should i be looking for something watch specific?

is this compound from the video what's commonly used?  it says on the product page that it's for gold and silver rather than SS

https://www.amazon.com/DIALUX-JEWELERS-POLISHING-COMPOUND-forGOLD/dp/B00TZVMXZA/ref=sr_1_2?ie=UTF8&qid=1485665653&sr=8-2&keywords=dialux

is there maybe a sticky on this topic that i've missed?  any help is much appreciated.

Hello camineet...I will consider the third link for the dialux bars and on bottom of the amazon page are the combos with cotton and wool felt wheels ..I use those with my dremel. In some cases you will also need fine sand paper or the 4 color nail polishing bars to get rid of hard scratches...I'm a novice with only 4 yrs of "experience"...that have worked well for me.
Good luck..!

oh cool thanks CapMoy

which cotton and wool felt wheel product do you mean? there's a crapload of other products on that amazon page. can you specify?

Posted

Any of these....Cotton is softer than felt so depends on the condition of the metal damage is what I use...cotton if looking for shine only...fine scratches felt first then cotton...for SS use the green paste.

ok so the basic idea is cotton buffs and the Dialux 3 compound pack. and then you just go at it with the dremel until you develop the technique and feel for it i guess

is that for SS and hardlux? or is there something else i need to get for hardlux?

oh ya, i have a battery dremel and was doing a shark mesh cut-to-size job in the hallway of my bangkok hotel last week xD

need to get a proper corded dremel sometime for added power and lack of battery swap hassle

 

ok, so felt for the scratches and then cotton for the polishing up.

 

thanks a lot for helping:biggrin:

 

so what about hardlux? same tools and compound?

Posted

And yes you will need a corded dremel one with high rpm...I spent 90 dlls on mine but I guess 

You may find a good one for less money . I spend 15 dls on first one I had , shortly after went for the hi rpm dremel...

I recommend that you use diamond paste from Aliexpress for the crystals, It made everything faster and easier for me compared to wet paper. For buffing and polishing Dialux is fine, rotation speed does not have to be high but you need a good torque for the deeper dings and scratches. Get hard felt wheels of at least 1" diameter, not the soft round ones.

I think that you can find the same items on Baidoo (sp ?). Cousins UK ships worldwide and for low cost items shipping is cheap with no customs problem. For Dialux get orange for deep scratches, gray for medium ones, green for finishing.

it's actually taobao that we use here in china.  and they have dialux and all these other items for about 1/3 the cost of anywhere else in many cases unless they're foreigner specific products in which case they cost around double. as for little tools and such, they're the same products for half or 1/3 the price of amazon, or anything in the UK. it's just that when you don't involve westerners and our bloated education and in some cases healthcare costs, and the only people in the value chain have bachelors degrees that cost 12kUSD, things just become a lot cheaper.

any guidance on masking? for example, how do you polish a crystal while not hitting the bezel with the buffing wheel? and how do you polish a bracelet spot with a brushed finish when there's a mirror finished spot right next to it and vice versa? do you put down tiny pieces of masking tape or something?

 

Posted

Yes if you are afraid that the wheel slips to a brushed surface you better use some tape masking. However usually the contact is brief and light and does not do any damage that an application of a brushing pad won't fix. What really does damage is if you slip and the case touches the chuck, so better keep the tool mounted on a vice.

For bracelets with mixed sections use a wheel thick as the section to polish, that works good e.g. on SKX Jubillee bracelets, you know, the ones with folded ends links which are very popular in Bangkok, LoL.

oh goodie, I finally get to use my kapton tape again. I reluctantly bought that stuff to redo the thermal compound in the 1990s car audio amp. $10 for a little roll of tape was hard to justify at the time. Glad to know I can use it for something that will be an ongoing thing.

Just now I'm putting together a big 'ole shopping cart on taobao with all the goodies we discussed.

jdm, this product listing offers numerous grits. can you let me know what which grit(s) i should purchase for the crystal buffing/polishing?

Posted

hey CapMoy, can you let me know what kind of rpm capabilities i should be looking for in my new dremel? i've learned that high rpms is useful for producing the heat needed to move metal around rather than just grinding it away. fascinating ability i had no idea was possible until doing some learning today

Get No. 5 and 20 diamond paste. I've found not much use in the others and there is no noticeable difference from a grade to the next.
For buffing steel you need slow rotation like 2000 rpm and apply sensible friction to the piece, plenty of heat will be generated. High speed only consume the wheel and the part being repaired.
Because of that a dremel like tool is not very suited as it doesn't have enough torque and turns too fast, exception is detail work and final polishing. A drill with variable speed works very good for me. Do some experiment on something like a big bol before attacking a loved watch.

Orange for true deep buffing.

Gris and verte are French for gray and green used for firts and final polishing. You can remove small dents with gray, but it takes a lot of time. Use a separate wheel for each if possible. You can also cut grooves like tyre on the wheel and reverse it every once in a while to make it more effective. Otherwise the surface hardens too much.

seller sent me 7 and 28 diamond pastes instead of 5 and 20 that i ordered.

 

when inquiring to seller, seller responds that "they are similar"

 

should i just go with the 7 and 28, or should i demand the 5 and 20 sent?

Posted

Just a quick point.

 

A Dremel has no where near enough torque.

You need a variable speed bench grinder with the proper polishing and buffing wheels.

 

This is the best tutorial out there for restoring SS watch cases.

Right, no practical difference as mentioned above.

    • it would be nice to have the exact model of the watch the or a picture so we can see exactly what you're talking about. this is because the definition of Swiss watch could be a variety of things and it be helpful if we could see exactly the watch your dealing with then in professional watch repair at least some professionals they do pre-cleaned watches. In other words the hands and dial come off and the entire movement assembled goes through a cleaning machine sometimes I think a shorter bath perhaps so everything is nice and clean for disassembly makes it easier to look for problems. Then other professionals don't like pre-cleaning because it basically obliterates the scene of the crime. Especially when dealing with vintage watches where you're looking for metal filings and problems that may visually go away with cleaning. Then usually super sticky lubrication isn't really a problem for disassembly and typically shouldn't be a problem on a pallet fork bridge because there shouldn't be any lubrication on the bridge at all as you typically do not oil the pallet fork pivots.  
    • A few things you should find out before you can mske a decision of what to do. As Richard said, what is the crown and all of the crown components made of . Then also the stem .  The crown looks to have a steel washer that retains a gasket. So be careful with what chemicals you use to dissolve any stem adhesives or the use of heat. You might swell or melt the gasket unless you are prepared to change that also . The steel washer maybe reactive to alum. Something I've just used to dissolve a broken screw from a plate. First drilled out the centre of the screw with a 0.5mm carbide . Dipped only the section that held the broken screw in Rustins rust remover. This is 40 % phosphoric acid. 3 days and the screw remains were completely dissolved, no trace of steel in the brass threads. A black puddle left in the solution.
    • I suppose this will add to the confusion I have a roller jewel assortment. It lists out American pocket watches for Elgin 18 size and even 16 size it's a 50. But not all the various companies used 50-50 does seem to be common one company had a 51 and the smallest is 43. American parts are always interesting? Francis Elgin for mainsprings will tell you the thickness of the spring other companies will not even though the spring for the same number could come in a variety of thicknesses. But if we actually had the model number of your watch we would find it probably makes a reference that the roller jewel came in different dimensions. So overlook the parts book we find that? So it appears to be 18 and 16 size would be the same sort of the arson different catalog numbers and as I said we don't have your Mongol know which Log number were supposed to be using. Variety of materials garnered her sapphire single or double but zero mention about diameters. Then in a section of rollers in this case rollers with jewels we do get this down in the notes section Roller specifications but of course zero reference to the jewel size. I was really hoping the roller jewel assortment would give us sizes it doesn't really. But it does show a picture of how one particular roller jewel gauge is used  
    • Seems to still do it through my mobile data, I use an android phone almost exclusively, but I'll double check it. Thanks mark Strange, I'll try my laptop that utilities edge. I've been on site half hour since I got home, it hasn't done it yet. Thanks John
