B912EC Bock 250 Housing for Pilot 912 Nib and Feed with Pilot Converter Nipple

Description

B912EC Bock 250 housing allows use of a Pilot 912 (size 10) nib and feed into custom fountain pens that can use Bock 250 threading. This housing has a nipple for Pilot cartridges and Pilot converters like the CON-70.

Manufactured in the USA by Flexible Nib Factory LLC from black ebonite from Nikko (Japan).

Pilot 912 nib and feed not included.

NOTE: THIS HOUSING WILL NOT FIT MOST BOCK 250 PENS AS THE PILOT CONVERTER IS PROBABLY TOO LARGE. IT IS MEANT FOR CUSTOM MADE PENS THAT USE BOCK 250 THREADING AND HAVE BODIES LARGE ENOUGH TO CONTAIN A CON-70 CONVERTER.

Installation Instructions

Remove the feed and nib from your Pilot pen:

• Empty your pen of ink in your usual way and rinse out the residue.
• Before removing the nib and feed, note the position of the nib in the section. You will want to have the nib and feed fit similarly in the J743E housing.
• Grasp the nib and feed, at the base only, keeping your fingers off the tines and tip of the nib, and pull them straight out of the pen. If the nib and feed can’t be easily removed, soak the nib and feed in a dilute household ammonia solution for a few hours, and this should allow you to remove the nib and feed from the housing. As a last resort, the nib and feed can be removed using a nib block and punch, but this method should not be necessary unless the pen has been allowed to dry with ink inside.

To install the Pilot 912 (size 10) nib and feed into the B912EC housing:

• Place the Pilot size 10 nib on the feed so it fits securely and snugly into the slots on the end of the feed.
• Without twisting, and keeping your fingers only on the base of the nib and feed, insert the nib and feed fully into the housing. The markings on the nib should be aligned as they were when the nib and feed were installed into your Pilot pen’s section.
• Remove the nib assembly from your fountain pen by rotating the nib assembly counter clockwise.
• Install the J6P5EC nib assembly by screwing it into your pen’s section. Do not over tighten.
• If you are using a converter or cartridge, install it into the section, then reassemble your pen.
• Ink your pen and enjoy.
