Just found out this amazing forum!
I already posted on the subreddit but will post here with more photos and updates.
I’m working on a custom pencil with the clutch from P203, i’m planning on building a full metal internals by removing the plastic lead container and making a brass one following this great resource: https://www.flickr.com/photos/48329631@N08/albums/72157715041741351/ .
I made the jig using a 3D printer and plan on using glue instead of soldering.
More photos and renderings: it seems i can only post one media as i’m a new user
I assembled the pencil with the full metal internals and stock P203 tip.
The weight is 16g, i will try experimenting with a brass tube to shift the balance point more to the front and bring the pencil near 20g.
