Simple segmentation with CA matt finish

[Brumar72]

Hi all,
I'd like to share my latest pen: made of swartzia and ebony wood with white styrene ring accents.
Requested by the customer I did a matt CA finish. As for the glossy finish, I applied several coats of CA, then sanded with 320/400 grit to flatten the surface: then again CA to fill small gaps, if any, and then up to 3000 grit. Then I polished with oil and tripoli powder. At this point, instead of buffing I went back by sanding with 3000 grit, down to 2500 and so on, stopping once I joined the desired matt finish. The last sanding has been done without the blank turning, but very lightly along the wood grain to avoid micro scratches.
Hope you like.

Very nice work !!!

Thanks for the details of your finishing technique .... I like the durable CA with a matte finish as you have done.

Very nice. I like the attention to the proportunate increase in the lower segments; very nice touch!

Thanks Mark, I just followed the golden section proportion.

Thanks Mark, I just followed the golden section proportion.

The visual symmetry of that equation is timeless! Very nice.

@Brumar72

Can you please remind me about what the "golden section proportion" rule is ..... I think it is something like 1.4xxx .... or 1.6xxx ....

It's a ratio that the folk who know these things say is "found everywhere in nature" - which it is, I believe. It's represented by the Greek letter "phi" and is equal to (1 + sq root of 5) / 2.
Which equals (approx) 1.62
(Yeah, I'm an engineer)
HOWEVER - let's not get distracted away from this gorgeous pen. I agree that the proportion increases are right on and also offer that the ebony at the top makes it a first class piece. WELL DONE!

Yes, as Ted said it's equal to 1.6180339...

Thanks for both replies ..... I remember most "special numbers" to several decimal places, but not that one ...... I guess I am not an Artist !!!

For me, it might be easier to remember ..... ( 1 + root 5 ) / 2 ..... = 1.6180339888..... a phone in Adelaide Australia, add in the decimal pt. !!!!

I like it! The design has me pondering as if looking at a painting, but it is art after all. The finish pairs perfectly with the hardware, too. I second the thanks for sharing your finishing method.

Since I was also wondering Mal, here is some reading material I found on it. The golden ratio. Sounds like an awful lot of precision measuring and cutting to me. If I use this, you can count on me doing some rounding off on the numbers. The spacing is certainly appealing to the eye, though. I wonder, did the first application of "the rule" start with the total barrel length, and then was applied to the shorter length, and so on, working toward the nib?

Very nice.

Thanks a lot Todd.
The spacing of the white rings does not apply to the whole barrel length since I planned to insert them only where placing the fingers when holding the pen. I first set the position of the ring closest to the nib, then, according to the rule of the golden section, i set the position of the second and with the same approach the third. Of course with so small surface to work on there are some approximations.
To be able to be more accurate I chose the swartzia blank slightly larger then 20x20mm so to insert the white styrene pieces just cutting 3 scarfs without separating completely the wood; it also helped to keep the grain of wood perfectly aligned.
I hope to have been clear enough (unfortunately my English is poor...)

Yes, that's very clear. There are plenty of people that speak only English and still do not speak it as well as you. Thanks for explaining.
