I guys, I bought this pile of parts from eBay the other day :-) a EK1, mm CD800, complete but with a broken of and tried to repair catch ( the catch is wrong). It seems that the cross came apart on the attempt to ( soft) solder the catch ! Anyway, since I didn't have a CD800, I figured it was worth a try, to repair this one, and fun too ;-) At a price of 70 euros I felt it was ok. I have made step by step pictures to show the repair process . Above the pile of parts to start with :-/ Next, ALL the old soft solder has to be removed from the back plate. If ANY of it is left, it will "eat" the silver, when the new catch is hard soldered in place ! New catch is drawn and cut from 1,2 mm silver plate . Catch is ready for hard soldering, using special paste silver solder . Soldered in place :-) After cleaning the flux residue in sulfuric acid, the inside is cleaned again, and the complete cross lined up for final assembling and soft soldering ! Cross after soft soldering. The cross is washed to remove the soldering water. The edges of the cross is gently smoothened with a fine file. Last the edges are buffed, using a buffing brush and corse compound ! Last but not least, the cross gets it patina back and oiled a bit :-) The final result is below ! I am pretty satisfied myself ;-D PS if you one day encounter an EK mm MC, it is made in Denmark by me !! ( just kidding)
