First time I took my PCR apart (to polish internal parts) I lost part #15, the firing pin block lever spring. Easy to lose, not often found. And, old news. This time, I was in a hurry (I had decided to polish the hammer). And, this time I lost part #63, the fixing insert. (Also very small, and just as good at hiding). After a diligent search, including running the vacuum cleaner and sorting through the dust-cup... no luck.
I called David at CGW and was told that he did not sotck the part. However, he also suggested I try a hobby shop or computer repair shop as they might have a small washer that I could substitute. Good Advice! I went to my local hobby shop and found 2.5mm washers that fit perfectly. Total cost, 89 cents, plus tax, for eight washers. FYI, and thanks, David.
Oh yeah, I may never take my PCR apart again!
