I wanted to make a modified pen that didn't look like a modified pen, so I set out to adapt a euro pen kit to take a parker-style refill. First off, I drilled out the nosecone with a #38 bit. Then I pulled the plug from the end of the refill, turned it down, and threaded it with a M5 x 0.8mm die. That way, it will screw into a standard 7mm transmission:

Normally, I avoid modifying refills, but since a customer can pull the plug out and stick in into a replacement refill, I think it's ok this time.

When attached this way, the transmission will need to be installed in reverse orientation, which necessitates a couple other design changes as well. Standard euro tubes won't grip the tube in this placement, so I cut new ones from some 7mm tube stock. This photo shows all the parts, with the refill screwed into the transmission. The transmission will press into the short upper tube.

I didn't want to change the outside appearance of the pen, however, so I cut the blank such that the tube would extend from the lower barrel, and the tube would be recessed in the upper barrel. Part of the reason I chose a euro-style over a slimline, was to allow a thicker (and therefore stronger) unsupported section of the blank. The blank is made from alumilite white resin, which is strong and durable even without a brass tube. I selected a green marble pattern. This is the pen completed but with the halves separated.

And here is a photo of the finished, assembled pen. The only oddity, is that the refill extends with a counterclockwise twist (opposite how a regular slim/euro pen twists).

I hope that was interesting,

The only issue I see is when you need to refill it...
When the ink runs out, I'll simply unscrew the refill from the transmission; pull the modified plug out of the refill; remove the plug from new refill; push the modified plug in the new refill; and then screw it back into the transmission. If I planned to sell the pen, I'd probably make a nicer looking threaded plug from a piece of brass, or maybe black Alumilite.

Regards,
Eric

Nice mod Eric...and it doesn't look like a modified pen. BTW, Berea has the Euro pen which uses a Parker refill. Looks the same as the 7mm Euro. You may already know this but thought I would let you know just in case you didn't and need more.
Do a good turn daily!

Lau Lau woods also has a double twist euro called the Neopean. It has a different clip though. Plus it's larger than a standard euro. Probably the same size as the Berea double twist version.

And I also think it's a cool mod. Good job! :good:

The Berea european pen that takes a Parker-style refill uses 8mm tubes. I wanted to use 7mm tubes and transmission. I originally intended to make a slimline pen (and could have) but decided that the thicker upper barrel of a euro pen would be better for an unsupported blank.

I suppose this modification would work work well on a Russline style pen.

Great!

FYI - had left a comment here earlier that I used a #40 bit for something similar with a Parker refill... I ended up using #38 as well as it would occasionally catch with a #40.

Thumbs up on your efforts.
