Leitz Phaco condenser centering keys - trade /swap

#1 Post by patta » Wed Jan 25, 2023 8:01 am

To vintage Leitz owners

I have two extra keys for centering the Phaco condenser (Leitz 402a turret)
Those are not the original unobtanium Leitz tools, but watch keys #5; they fit perfectly and do the job. Only defect is that they're so small, easy to be lost.

I will send them as letter; plz provide photo proof of having the Phaco condenser; would swap for some other valuable treasure, for example: a couple of mounted slides; a random objective/eyepiece/condenser/ λ/4 plate; something that can be sent as letter.

See this nice article about using watch keys for centering the Phaco; standard watch keys need some work. Mine came readily usable:

I'm intrigued! But I have a Nikon 4-objective nosepiece with centering adjustments. Nikon centering wrenches:

..... which show up rarely on e-bay, are always outlandishly priced. Now knowing that "watch keys" may be used has given new meaning to my life!

If it’s any help …
That Nikon wrench looks remarkably like a hex-socket grub-screw with a knob attached.

[ plenty of other suppliers available, but it’s a nice list ]

For those too far away to take up Patta on his kind offer -- hobby shops sell tiny brass tubing with square sections whose ID will also fit the Leitz 402a. Maybe (don't recall) with a bit of persuasion to open it or close it down a bit to rectangular form. Epoxy that square tube inside a bit of close-fitting stainless tube to add some strength, chuck it in a drill to sand down the end of the outer stainless tube to fit, then add a knurl at the end . . .

Holy COW! You're right!

I was wondering why that shaft was threaded; seemed a little weird.

Yet another clue! Thanks MichaelG!
