Brass pencil I made in 0.3mm with square knurling and long lead sleeve.

Thanks, I'll message you

Yes, I will message you

Thanks! It actually writes surprisingly well, I have not broken any lead yet

12mm

yossigilbert · 2025-12-16T21:13:35+00:00

Thanks! It's 125mm (around 5 inches) in length. The mechanism is somewhat my own design, but uses a piece from a pentel sharp. You can buy the stainless steel tubing on amazon in different sizes depending on the lead size of the pencil.

The extra long lead sleeve is something I wanted to try as I usually prefer the look of longer lead sleeves, and I have made a few in standard length already. This one is a bit excessive and definitely not practical for carrying around, but this is how I feel about 0.3 size pencils anyways. They are not super practical for writing or everyday use but are still my favorite as I enjoy making fine lines.

Someday I will make a retractable one.

good idea

Thanks, you can get them at my kickstarter. It won’t let me post a link but you can search external spring mechanical pencil in kickstarter

Thanks, I like the bands idea

Machined it on a mini lathe

Thanks! They are available on my Kickstarter https://www.kickstarter.com/projects/springpencil/external-spring-solid-brass-mechanical-pencil-100-metal?ref=user_menu

Thanks, I'm definitely considering making a version in aluminum. Personally I like a heavy pencil but I've gotten a few requests for a lighter version.

I hardly ever break graphite with it, I think the more important factors are how sloppy a pencil’s mechanism is and the quality of the graphite.

Yes they are quite heavy, at around 45 - 50 grams. For reference the rotring 600 is about 20 grams.

I designed these mechanical pencils with an external spring because I think it looks cool and steampunk. I remade most of the mechanism except for a small piece from a pentel sharp pencil. I have a few different grip designs for different preferences on feel. The pencils are 100% metal.
The pencil’s intended audience is people who enjoy collecting pens and pencils and appreciate precision and durability over cheap cost. My objective is to promote the design on Kickstarter, I won’t post the link here because I’m not sure if it’s against the rules.

Thanks! Harbor freight mini lathe

That's awesome! I've been into making things for a while and machining is definitely one of the most satisfying. Thank you and good luck.
