A shear pin (retaining pin) was sheared on a friends CPP...and oh how
much fun it is to replace!

The center part of the pin was not coming out so...time for the Dremel!

After a "slight" grinding, the shaft came out and now all I have to do
is get the rest of the shearing pin out and re-build everything. It's a
great learning experience...like surgery, but on a smaller scale.

I have found: keep some different types of hemostats handy (curved and
straight) for the really small parts.
Dermels are very handy for small work also. Find some very small
zip-lock bags and always put the parts in them as quickly as you can
after removal. (You'll almost never find them if you drop them) Also a
good "stand mounted" magnifying glass (for us "older" folks) will help.
Get a cold-heat soldering iron and keep the refrigerator full of the
beverage of your choice and always...tell the Wife you'll be done
soon...yeah right. (They know "soon" means probably after midnight
somehow...but don't expect any "Sierra Echo X-ray" after a late night
repair job ;-)
Keep smiling, learning and flying...
