More Very Bad Attempts at Wear Repair

其他磨耗維修的糟糕嚐試

The repair above gets the award for clever use of a straight pin.  The soldered on pin is pushing against the pivot to try to hold it in its proper place.  Pretty isn’t it?

上圖,可以拿到插銷聰明應用獎。焊上去的插銷對支撐軸推向正確的工作位置,很帥是吧?

This person did not even exert himself enough to get some band-aid bushings but instead gave this clock got the deluxe treatment with crude chunks of brass soldered over top of the worn bearing surfaces.

這個圖顯示維修的老兄甚至連帶邊的襯套都不用就直接用豪華處方的大塊的銅材料銲到磨耗的軸承上面去

 

This clock may have actually been taken apart to install these bushings but look at the “very fine” method used to hold them in place.  Pretty isn’t it?

 像這個相片的鐘或許有拆解開來裝入襯套,但看細部的固定方式;很漂亮嗎?

 

With the exception of perhaps this last picture the one thing all the preceding pictures have in common is that an attempt was made to repair the worn clock without dismantling it. It is practically impossible to do this without defacing the clock and rarely results in a durable repair.

 除了最後這張相片外,幾乎所有前面的照片都顯示一個共通的意圖,就是不想拆解時鐘的機芯就要維護磨耗的鐘。這樣做是實際上不可能不毀傷鐘的,也幾乎達不到耐久的維修。

 

Worn Bearing Surface Repaired Properly

磨耗軸承表面正確的修復

Now that’s more like it!  This side by side before and after photo shows how a repaired bearing surface is supposed to look. 

現在該像這樣才對! 這個將修護前與修復後的併排比對,顯示修復的軸承表面應該看起來像這樣。

The left side shows the oval shaped hole, without prick punch marks thank goodness.  The right side shows the same area with a properly installed bushing.  You almost cannot tell that a bushing has been installed except for the slightly different color of the bushing.

左邊的圖顯示一個橢圓孔,謝天謝地沒有被側敲復圓過。右手邊相同區域顯示的是正確的裝入襯套後的圖,除了襯套的顏色有些小差異外,你幾乎不能看出來有裝入新襯套過。

 

Improper Use of Solder

不當的使用焊接

Solder Blob 銲斑

Pretty isn’t it!  The dark spot just above and to the right of the solder blob is a pivot.  I am not sure what this person had in mind here except they obviously did not have a clue as to what they were doing. 

不漂亮吧!  在銲斑上端右邊較暗的點是支撐軸。我是不確定這個維修人員心理是在想什麼,除了很明顯的對他所做的感到毫無頭緒。

The discoloration of the brass plate is typically caused by flux, which is used to prepare an area to be soldered.  After the soldering is done the area must be cleaned or this type of discoloration will only make the idiotic repair look even worse.變色的銅板部分是典型的由助銲劑所導致的, 他通常用於準備銲接的區域。再焊接完成後這個區域是要清理乾淨的,這樣的退色只不過讓這種白癡的維修更難看罷了。

 

Soldered Escape Wheel Bridge

焊接擒縱輪的架橋

Okay, here is a new one.  This is kind of hard to see in the picture but this "repairman" actually took a small thin piece of brass, bent it over to a right angle, inserted one end into the elongated bearing surface moving the pivot back where it belongs and then soldering it in place. 

好的,這是一個新的案例。這是一個很難從圖片上看出來的事,維修者實際上取一個小銅片摺成直角,將一邊插入磨耗延伸的軸承面,將齒輪軸推回原位再焊接定位。

Like the previous picture the soldered area was not cleaned up afterward.  The flux has actually caused the steel pivot to rust.  Beautiful!  This type of repair is bound to last a long time.......not!

正如先前的圖,和好後也沒清理。助焊劑也讓鋼的軸鏽掉了。美嗎?這樣的維修可以持久不對的。

 

Corroded Movement Due To Solder

焊接而鏽蝕的機芯

Does this need any explanation?  This movement was a disaster, almost beyond repair.  In fact, the cost of repairing this mess got so high the customer did not allow me to restore the entire movement.  Rust and corrosion had practically eaten its way through one of the gear arbors.

 這不需要解釋吧?這個機芯簡直是個災難,幾乎不能修了。實際上,維修這個爛貨花費很高,客戶不願讓我去重建整個機芯呢。鏽蝕及侵蝕實際已經吃掉其中的一個輪軸了。

The previous repairman had soldered a new piece onto the striking rack, soldered a new tail onto the rack hook and it even looks like it was done without removing the parts from the movement as the steel parts immediately surrounding this area were all rusted and corroded.  This was all a bad idea to start with but he could have at least cleaned up after himself and saved the movement from even more destruction.

先前的維修人在鳴鐘的齒條上焊了一個新的齒條,甚至看起來好像維修時沒將零件自機芯移開因為在這下面的鋼的零件都鏽蝕了雖然這樣的維護全然是不好的開始,但是至少要清理乾淨及避免機芯進一步的損壞。

繼續...
