Evening all

Just bought this clock and was wondering if i should polish the case or leave it as is. The picture makes it look a lot brighter than it is in reality, would you consider tarnished brass as patina, my personal thought is that patina is more a case of wear / distress due to repeated use / rubbing over a period of time.

Looking forward to your thoughts.

I am not big fan of polishing vintage or antique watch cases or clocks. Leave it as-is.

How would you like it to look. Looking at the photo it looks as if you collect clocks. If you do decide to polish it when that is done use a clear  lacquer this will prevent it from tarnish. I don't like seeing a brass clock case caked in old dry brasso which has turned green or a whitish powder.

This all comes down to your personal taste, these brass clocks are bolted together from many separate castings to clean the case properly you would have to break it down to its component parts in order to clean, I would soak in a weak clock cleaning solution, then clean with Brasso and re soak the parts and then clean in detergent.

As you have pointed out the idea is not to remove every defect or scratch you see, it is an absolute must to lacquer the brass after cleaning or all you work will soon be lost and the case will again tarnish.

Clear lacquers will not alter the colour of the brass, but you can also buy gold tone lacquers these if applied correctly will give you a finish almost indistinguishable from a gilt case.

The clock below I have just finished its a carriage clock that I bought years ago but have just got round to servicing, the case on this was very tarnished and dirty with plenty of old polish, the brass was also pitted this I can live with so would not try to polish it out I used a mid tone gold lacquer mixed 50/50 with a clear lacquer to get the tone I wanted, the clock should remain like this with no need to polish for many years.

Good evening all

thanks for taking the time to reply. 

Poljot, looks like it's going to be a polish on this one. 

OH, WLS1971,I think I will polish it maybe not to a brilliant polish, I will start with a good clean as WLS1971 suggests with clock cleaning solution (i have some that has been used so is weak) and see how it looks, then a light polish, basically take it one step at a time until I get the finish that looks right. WS1971 I think I will get some toned lacquers and do some test applications for future reference, but probably use clear on this one. The brasso residue does look awful, I think I'm going to need a supply of tooth brushes.

Your right it does look like gilt, looks really nice.

Thanks for help it's much appreciated. Cracking forum.

I admire your courage! There will be lots of work!

I left my Japy Freres clock as-is. Well, not exactly as-is. I disassembled the case and the movement just to clean the case gently and to service the movement.

Hi Poljot, This may end up just being a gentle clean, I'll take a step at a time until I get the look that I think is right. It will be a while before i get round to working on this as I have a tortoisesheel boule bracket clock and a "monastary clock" that are ahead in the queue as well as 6 longcase clocks to restore.

When restoring a clock you need to know what it would be like when it was new. You should take it to that stage and nothing more. You could alter its value to the extent it could end up worthless. In my time I would always follow after researching the methods that were used in times past. Whatever you do don’t use motorised tools such as polishing mops or those dreadful dremel tools.

I think that I'm going to have a similar dilemma with this pewter cased electric clock when it arrives.....

I found a picture of a similar pewter cased Ferranti clock and like the appearance, but how to achive the same look on my one?

There's plenty of ways to clean Pewter on google. My biggest concern would be that dial.  

I think I have got that covered as I have this one, with the same movement, and almost identical dial, incoming...

Yes providing its the same size. 

Yes, both 3 1/2" dials, most of the early Ferranti electric clocks up to about 1936 had the same dial size.....

Hi OH, Any idea what method would have been used in past times, i would have thought some kind of abrasive paste or "0000" steel wool(probably a bit harsh), I too dislike powered polishers for clock cases or parts.

Posted

I would use Crocus cloth with warm water or you could use petrol. If there is any wood in the case just dip the cloth into the fluid do not submerge the case. 

Posted

Hi OH, Thanks very much, never heard of crocus paper had to google it, so that's my bit of learning for today, i see meadows and passmore stock it.

Thank you

Oh ye of little faith?, original dial carefully cleaned with cotton buds, initially using saliva ? to disolve the main stain, then VERY carefully with mild soap and warm water to bring the less virulent discoloration off......I missed my vocation in life as an art restorer?. Soap and water treatment on the case finished with a coating of car polish......

I’m not sure if you’re still mulling over this, but I noticed your comment about whether or not to polish your octagonal Ferranti pewter clock.  I purchased one a number of years ago and decided to polish it.  Thought I’d upload a pic of it for comparison.  Pewter is usually left with a duller finish, but I liked the shiny, almost mirrored look I got with gentle buffing wheel + simichrome

    • I believe @nickelsilver has a setup like that.
    • I posted pictures earlier in this thread. My lathe and mill are two separate instruments. I think I have seen examples of putting a milling head on a lathe bed...but not certain.
    • Timex Camper, September 1994, new to me. Strap is an old perlon with "Germany" in script etched into the resin on the tail end. Not Horlon or Eulit I believe. History unknown, running strong, losing less than a minute a day. Goals for this: Wear it a ton! Buy crystal lift, clean out the gunk around the ring and under the crystal Eventually swap into a stainless steel case. I've seen a member who has swapped a Timex mechanical movement into the Timex J.Crew quartz field watch case.
    • One of the problems we would have with a watchmaker's lathe is they were made over considerable span of time and manufacturing in the early days probably wasn't as good as it was today. Then if you look at the older catalogs typically it was just the head a few collets and something to rest graver on. So basically a basic lathe with over time things acquired but acquired things may or may not fit. Order today you purchase a used lathe that all kinds of nifty bits and pieces from a seller that acquired from? This would come back to that the basic watchmaker's lathe was used for basic watchmaking like turning things with a hand graver. Then limited indexing is fine because you can make things like stems Which don't need a whole bunch indexing   In the link above the word vector is mentioned and at the link below you can purchase one. Then of course you're going to need the motor that's a little bit extra for the price. https://www.hswalsh.com/product/lathe-vector-watchmakers-48-collets-hl11. That you're going to need some bonus parts like these found this picture online show the classic way of classic gear cutting.   The lathe could have a much bigger indexing disk but it has to be mounted close to the edge. Otherwise you're going to have a whole bunch of smaller disks like this which I think has notches rather than holes. Then as wonderful as these pictures look actually cutting a gear with this is not entirely fun. Look at all is belts all pulling on things and this is a watchmaker's lathe lightweight with lots of bits and pieces attached. It would make more sense if you actually cut a gear with something like this and it tends to be it's not really the best way to do it looks nice on paper but it is not the best way to go. Reality for cutting watch parts would be a bigger machine is much better. Than getting rid of all those belts and pulleys also good. Here is an interesting channel I would've liked of found a different video but this was nice and short if you look at his video as he uses a stepping motor and worm gear assembly for the indexing plate. In this particular video it gets attached to the lathe at about one minute and seven seconds and it looks like it's hiding looks like he has a Sherline. I do know he's had other stuff you'll just have to go through his videos to find it. Then at about one minute and 22 seconds you find out if you set up things appropriately. It's always bad we end up with half a tooth at the very end. Then you will note big lathe yes he's getting a big gear but you could easily cut a watch gear with the setup. And it definitely way more stable than a watchmaker's lathe.         Oh here's a company they been in business since 1911 http://www.fwderbyshireinc.com/
