Demonstrator...

If you've never attempted this, it's no easy task.

I had to create some custom tooling to get in there and clean out the
material.

My understanding is that the major manufacturers are either using
diamond-tipped tooling at super high speeds, or it's injection molded.

I don't know how many more of these I want to make...a real pain in the butt.

Pretty Awesome if you ask me!

It looks good, I certainly salute you for that effort. Most of the production pens I see like bic's and what not are deffinitely molded pens as I can see a seam.

 

[Jim15]

Absolutely fabulous, great work.

 

[Ozzy]

That's pretty cool.

Just 'cause there is a seam, doesn't mean its not molded. Many plastic parts are injection molded in halves, then sonic welded. Its a common thing to do and can be pretty darn accurate. I worked at a company one summer during college and watched them sonic weld MILLIONS of promotional items.

As for the pen... WOW... that just looks hard.. Very impressive work.

Awesome! Can't imagine all of the internal sanding required.

Outstanding job. Bic does use injection molding, I've been to the factory.

 

[toolcrazy]

Wow, that is cool. Nice work.

 

[Ligget]

[markgum]

Very Cool...

Brian, I have seen some demonstrators that just a small portion of the body is clear, Yours is amazing, I've been working on a clear acrylic slim line off and on for weeks, I have a faint Idea what you had to go through, Congratulations on an amazing job.

 

[nava1uni]

Very cool, it would be cool if it was colored but clear.

 

[sparhawk]

Great job! Cant hide any flaws on that one.

 

[kruzzer]

what great workmenship.... I bet there aren't too many like that one around...

 

[desertyellow]

Worth every minute spent sanding

Heretic! :biggrin:

Brian,

Interesting pen! Congrats on making the cover!

 

[VisExp]

Beautiful pen. That must have been a task to polish the inside of the blanks.

Congratulations on the cover shot!

 

[cnirenberg]

That is a great looking pen and it would make a great addition to the library's tutorials.

 

[PaulDoug]

great job amd congrats on being the feature pen!

Brian,
I have read on a duck call forum how to polish the plastics with a technique called "flame polishing" I wonder if it would work? Cut down on the internal polishing of the ink well.
i'm really curious if it would distort the threads, since they are using flames
