Condenser Pinion with Brass Gear For Nikon 50i, 55i, 80i

Here's what people who bought my replacement gears said:

"This vendor is helpful and reliable and deserves the custom of scientists. He is supplying properly-made metal substitutes for the plastic pinion gears of Nikon Optiphot microscopes. Throughout the world these superb microscopes are failing because of plastic components, obviously incorporated to create obsolescence after ten or twenty years of use. Without David's work, microscopes worth many thousands of dollars would be discarded."

"Parfait, merci @+++++.  (Perfect, thank you.)"

"What a find! My Optiphot had free-wheeling condenser and fine-focus knobs. The replacements dropped right in and I couldn't be happier. Highly recommended seller!"

"Accurately represented, shipped promptly & well-packed. Standard Great Transaction! An A+"

"Excellent product and the final piece to my scope. Why did I wait so long to buy it!!"

"Item as specified, quality product. Quick delivery to UK. Would recommend."

"Product was as described and worked perfectly."

"Excellent to work with, fast shipping AAA+++"

"Excellent seller. I would buy again from him."

"Great experience!"

This condenser pinion shaft fits Nikon Nikon 50i, 55i, 80i microscopes.  It's carefully made to exact specifications.

* This brass gear provides extended life over all plastics and it will obviously not react with brass racks (gears).

* Brass offers a softer, more natural, feel than steel.

Note:  Always ensure the condenser dovetail is lubricated with synthetic grease and moves freely before installing this pinion shaft.  Need grease?  Please message me and I'll include a small sample at no charge.

Please contact me for bulk orders or custom-made gears.

Returns are only accepted on unused and undamaged gears.  Any signs of installation and/or use will not be accepted.
