Case needed a lapping machine....So I improvised - Results are amateur but promising

Recommended Posts

I decided to do a little improvisation last night. I had a case where the sides were extremely worn, dented, etc. The case lines were nearly worn completely down.

I've wanted a lapping machine for some time but those are far too expensive for my humble budget. I improvised by hooking up one of my sanders to a voltage regulator to bring the speed down as much as I could. I put some 1000 grit paper on the disc and started to gently work the side of the case. I'm quite surprised at what I was able to accomplish with these rag-tag tools and bit of creativity. I'm limited by the table because it can only adjust to 45 degrees, so there are some angles on that case I won't be able to reach properly. While looking up pictures on the internet of other examples of this case it looks like there was not a sharp line between the side wall and the lugs, so I just tried to bring back a gentle curve between those to sides. Not too bad for my first attempt! I'm going to keep moving forward and go up to 2500 grit and see what I can get out of this before moving on to the polishing wheel.

Hi A tidy job. Improvisation sometimes produces remarkable out comes.   Nice one

Thanks.  I need to work on my photography, clearly!  The rebuild video came out pretty well, but I still struggle with getting a good still shot.  It's a skill that I have yet to learn.  I mainly rely on luck, which isn't reliable at all, haha!

Look great, did you re-brush the top edge or is that how it was ?

I re-brushed it.  Originally it had vertical brushing, but it was all but gone by the time I got the watch. The light reflecting off the top makes it difficult to see the brushing, but it actually looks pretty good in normal light.  As I stated earlier, I'm not a photographer by trade, haha!

I tinker with watches and occasionally upload a video to YouTube, including one for this watch.  I'm not here to promote my channel, as I've been a member here long before I began uploading content (started doing it at the request of a friend).  YouTube is just a hobby, and this is a place I can come to ask for advice, look at other's projects, and is a wealth of knowledge (on top of Mark's courses which I thoroughly enjoyed).  I did not want to sour that by trying to promote a YouTube channel here.  If you'd like I can send you a message with a link to the video.  I recorded the entire process of using the disc sander and brushing the case.  It isn't perfect by any means, but I think it turned out pretty well with the tools I had on hand.

    • Hi Fernando, read carefully what @eccentric59 wrote, it is the key to You problem. Lubricate the cannon pinion. Take care to understand what is it's function. When You set time, the train doesn't move, but only the cannon pinion moves. Put hte lever back in it's place, it has nothing to do with time setting
    • Hi fernando. Let us know how you get on.
    • OK, in You case You will assemble the movement with the line attached to the barrel and fusee and will  wind the line  entirely on the barrel after that. It is important when replacing the line to know the correct lenght of the line. The rule is that when line wound on the fudsee entirely, about 1/4 turn still to remain on the barrel. Yes, no tension. The ratchet is not placed yet, the spring in the barrel is complitelly unwound. At the end of the step the fusee is empty and the line is attached to it and strained perpendiculary to it, not on tangent. The escape wheel. Use whatever that will not damage anything. Yes, this is typing mistake, sorry. The word 'pendulum' here is not correct, You should use 'anchor' and yes, it is removed from the movement at this point, according my instruction 1 (Ihave used the word 'lever' there):   Ok, let sey the barrel arbour makes 6 full turns when winding the spring in the barrel from unwound to fully wound state of the spring. Let sey that the barrel makes 4.5 full turns when winding the clock from fully unwound (the line is on the barrel) to fully wound (the line is on the fusee) state. This means that You should not wind the spring in the barlel when adjusting the initial tension to more than 1.5 turns of the arbour of the barrel.  If You make 2 full turns, then when winding the clock, the barrel will be able to turn to only 4 turns, so the limiting device will not limit the rotation of the fusee arbour and You will be able to force the line much more than when the limiting device acts, also the power reserve will be less. Hope this is clear now... Yes, but again - not the pendulum, but the anchour.   About the loosing time... In this kind of escapement, the frequency pritty much depends on the torque. The higher torque - the highrer frequency. This is because this escapement forces the pendulum to oscillate significantly faster than it's own resonant fequency. The frequency depends on the 'depth' of the escapement too - the deeper escapement is, the lower the frequency, and the higher amplitude of pendulum oscillations. The heavier the pendulum is, the harder to the movement (the escapement torque) to force the pendulum to oscillate faster than it's own frequency. And in the end, the own pendulum frequency depends only on the pendulum lenght and a little on the suspension spring 'strenght' This are all the relations between all the factors. You can try to use the old spring (if it is not broken) and see if the clock will work faster with it. Yes, the old springs of fusee clocks sometimes give bigger torque than modern ones, no matter if they seem to be 'set' You can shorten the pendulum to achieve correct frequency. If the torque is reduced, but enough for the movement to work reliably,  then reduced torque will only lead to lessen the wear. The torque in fusee movements is more or less constant all the time, this is the function of the fusee. You can use the Clock Tuner  free app for android to adjust faster the clock rate. You will need to know the BPH of the movement, so count the teeth of the wheels and pinions and calculate the BPH
    • Hi! My bad. I meant to say that when the pallet fork is installed I cant move the wheels "using the crown in the setting position" Really in truly my number 3 was redundant and badly written (trying to explain myself went all wrong). I dismantling partially the watch (calendar, remontoir, Balance and Pallet fork). I think I would need to go that way...  Thanks for your comments...    
    • this is what happens if you don't fully do all of your research. I found the safe answer I found your exact caliber we got a mainspring number we got a price at a decent price for the original spring verified that the spring number at least on bestfit agrees with what we have so it was safe yes I did look in the GR catalog I had seen that 200 watch has a spring similar to what you perceive it should be. But to be honest I never looked at the 200 watch to see what its mainspring was. then the other amusement I went back to the bestfit online because if the 200 have the same spring I were to see that when I snipped out the image up above. Turns out they don't even show a 200 listing at all.
