Hi All,

Here is something that I found on the Marblack that might be useful, I think it was from M&P.

Clockboys pdf is also very good. I was never keen on using the polyfiller to stick, I always used good quality plaster of paris.. Although NEVER use on dry slate that you have just renovated because once you put on a thin layer you don't have much time to sit and set, before the water is drawn out and it has stuck firm, you will never get it apart, I always wet and let the water soak in a few times on the slate first so that it gives a little more time to move and line up properly, don't worry about any that messes your slate it easily cleans off.

A NO NO is to never use apoxy resin, use that and make your clock worthless, no matter how hard you try to be careful it will ooze out and seal the pores of the slate and WILL show up badly when polished..

First, may I apologise for posting on a rather old thread.  If anyone feels able to help with my problem, I would be most grateful.
I havde a number of black "marble" clocks with French movements, so their cases are probably Belgian Calcite.  Due to being kept in a damp room, they were attacked by mildew and peppered with white spots.  I have used "Cherry Blossom" black boot polish to remove much of the spotting, but it is still very noticeable.  "Kiwi" boot polish comes in two varieties - one is the "ordinary" type and the other "Parade Gloss".  When I last came across the latter, many years ago, I recall it having a strong smell of turpentine.  Would this "Parade Gloss" boot polish, if it is still available, be worthwhile?  The cases do not have significant white bloom, just the spotting caused by the mildew.
Any suggestions would be most welcome.

Hi  and welcome to the forum,     If the spots are well noticeable you will have to rub the cases down to remove them.  Mildew is a fungus therefore organic. You could try a propriety brand of mildew remover firstly having removed all the cover up material (boot black  etc) with white spirit. If that fails then rubbing down is the only other method.  attached document to help you.

      No John, we don't want Mark to change anything, we are just scared of losing a brilliant forum and losing contact with each other.  As pointed out, this forum is full of knowledge and I for one,  consider the regulars friends. I would hate to lose contact with you and the others.   PS, this forum is really important to me.

      Epilame / Fixodrop

      By JohnR725 · Posted

      one little minor problem with your chemistry experiment here which is what exactly is epilam? In other words is it an exact substance with the chemical you specify or is it a term? For instance originally it was steric acid either dissolved in some sort of solvent or it was applied by vaporizing it. Then now it's all kinds of different things the watch companies all have different ideas there's a whole bunch of patents. So is not always an exact substance.   let me snip out a image from the patent that I attached up above. Notice I highlighted something it seems to disagree with your evaluation.

      I guess You had to try, as it would be hard to sleep without that try, but, I know the result before the experiment... As I told before, the friction will be so big that the wheel will not turn. The pivots have to be thin and polished - the bigger the number of the wheel (2th, 3gh, 4th...), the thinner the pivot. What You are trying to do is possible, but forming the new thin pivot must be done on lathe. Thus the wheel will get shorter, but can have new pivot without the drilling for normal standard repivoting. Then piece of brass can be soldered under the pivot hole in the bridge and new hole drilled in it to form the new bearing.  Well, this way is not the recommended one, not quite correct, but it is possible to do for the excersize... When I say lathe, lathe may be verry simple, someting like turns, but made of what one has in reach of his hands. If You want to try, I will try to guide

      yes by all means let's gather up our weapons tar feathers find the nearest tree in case Mark is not agreeable to our terms on our demands and storm his Castle. I don't quite understand what you're trying to do here? In other words you want Mark to somehow guarantee that the group will live on forever no matter what? You want Mark to somehow change his business model of what is trying to do or should we just take the group away from him? oh and is quite possible that Mark never realized that his discussion group would take on a life of its own. That the members of the group would like to continue on forever.

      I'm not sentimental, I see it this way.  I inherit something I  don't like, I could sell it, buy something I do like and remember the person with the new item.  For example, I  inherit a watch ( I haven't), I don't like it, I  buy a watch I do like, every time I look at the watch, I think of the person.
