At my last job when we glued crystals into cases we used UV glue and cleaned it up with "Trichlor". The stuff worked GREAT It only removed the glue on the surface and I could get a very very clean seam. BUT I can't seem to find any place that sells it. So I was wondering what all of you use to clean up hardened UV glue. 

 

Thanks for your time.

not surprised you can't get it any more. I assume that it is trichloroethylene which is now banned almost everywhere due to its carcenogenic properties.

Does acetone not work at all? Failing that is it not possible to clean up any excess glue with IPA before curing it under the light?

Since you are in the US, you can get it, search ebay for  trichloroethylene.  It's gotten expensive, though, 500ml for about 50$ US. Nasty stuff, too. Be very very careful when using it. I use it as "One-Dip" for hairsprings and jewels, and try really hard not to inhale any fumes or get any on my skin.

A solvent often used as a substitute that is not quite as dangerous is Tetrachloroethylene, otherwise known as "perc" or dry cleaning fluid. I've found it sold in auto parts stores as brake cleaning fluid. I don't know if it will work as well in your application, as I don't use UV glue.

We had something in Sweden called bräkleen from CRC . But don't now if that has tri any more? Tri is not very good for the environment.

I remember once using 'triche' in my teens (many years ago!!) to clean some cycle parts in my dads shed.  My dad had a big bottle of it.  I can remember my head starting to spin (not literally!!) after only a few seconds.  I got out quick to recover.  Chucked the stuff and closed the bottle very tight!!  Never used it ever again !!!!

To think that it was widely used in the engineering industries as a degreaser/cleaner is frightening.  No wonder it is banned in the UK, although I think it can still be used under license with very strict rules and requiring very sophisticated and no doubt expensive ventilation/extraction/solvent recovery plant. Most of industry moved to other products as a result.

I believe it was originally developed as an anesthetic.

My other secret vice, other than watch tinkering, is reviving dead iPhones. I use UV glue on the screens and that cures to a rubbery texture. This peels off with a bit of rubbing and I would have thought a piece of peg wood would do the trick here.

I agree with the often repeated idea that glue goes with watches like sardines go with custard but why use a UV glue to further complicate matters?

Using a solvent on glue just turns it into thin glue.

Just done a straw poll in the phone community. Fluids used to remove the glue range from engine oil to electrical contact cleaner via WD 40 and olive oil. Plus mechanical removal by rubbing, scraping etc.
An almost 100% vote for IPA for final clean up.

      Not a family member, and yes, it no way near as good, as some information got lost from original site and some information got incorrectly copied. The original site is available as iOS app here: https://apps.apple.com/fi/app/ranfft-watch-movements-archive/id6502008939

      Seitz Tool - Help determine if Seitz or not

      By Hawaiikook808 · Posted

      Outstanding, Marc! Your information is really helpful and clears this up, especially given that yours were purchased as sets. Thanks, man. So, it appears I jumped the gun on this one, but I am relieved. I will say, though, that all of my reamers and concave pushers are number-stamped and appear to be of better quality.  Also, the bayonets on my pushers are actually the same color as the steel.  The next thing to do is restore the heads of these pushers with some polishing paper.  Alex at the Watch Repair channel has a nice little video on this.   I appreciate your help!

      Just installed it on my iPhone (my only iOS device) and it appears to be intact and functional. I may have to go out and buy myself an ipad just for this app.

      Seitz Tool - Help determine if Seitz or not

      By Marc · Posted

      I have two Seitz sets, one ancient (with the 3mm anvils) and one just old (with 4mm anvils) plus a collection of spare pushers of assorted vintage. Not one of them is marked with it's size. Something which I have found very irritating when I have been using the tool and not returning pushers to their correct place in the tray every time as it means that I have to get the calipers out and measure them. These were bought as sets and collectively I have over 100 pushers so it would seem highly unlikely (if not inconceivable) that they are all cheap knock offs, especially as they are old enough to pre-date the prevalence of the Chinese knock off industry (at least as applied to watch making tools). I therefore believe them to be original Seitz parts. And there is no numbering. The shape of the bottom of the pump pushers is the same as your photo. The only thing that may not be the same is that the slotted insert (looks like a screw but is in fact a bayonet) should be brass. Yours looks the same colour as the steel but that could just be the lighting.
