Item description for Stripped inner gear replace Boston model 18 / 19 pencil sharpener X-acto 18xxxCN

We've developed the repair / restore insert for a stripped inner gear for

Boston Electric Pencil Sharpener Model 18 and 19 stripped inner gear (blade assembly guide)

Also will fit X-ACTO ELECTRIC PENCIL SHARPENER MODEL 18XXXCN

This fine Nylon gear has improved design for better durability and performance

Our gear is 20% thicker compare to OEM

It fit rotating blade gear better than original thanks to 20 degree bevel angle

3D printed out of Nylon - tough and flexible plastic

Only Nylons should be used for gears where a slippery surface is desired.

All other materials (PLA, ABC, PET, etc.) will grind creating a plastic dust and eventually fail!

Installation require some mechanical skills:

a. Take unplugged sharpener apart

b. Cut stripped part off to the length of ?8mm (0.3")

c. Drill two 1/16" pilot holes and attach new gear with 2 stainless steel screws (included)

(shavings release opening must face down)

d. Unscrew steel cutting blade shaft, clean and lubricate

e. Assemble in reverse order

For details, please review all pictures.
