TWSBI VAC 700 update 11/25/2010

2010/11/25 更新 update
這筆最大的考驗之一是在筆冠與筆夾的製造工藝,本來是想用 diecasting 但效果總是達不到標準。幾經輾轉終於確定筆冠用 CNC 車床加工,筆夾用脫蠟鑄造,兩者都是非常昂貴的工藝,但效果一流。
今天終於拿到筆夾樣品了,還沒精加工但是基材已經是非常棒了。
One of the major difficulty on manufacturying Twsbi Vac 700 is how to fabricate the crown and the clip. We were intend to use die casting method, but result turn out not satisfied. By tring several differenct solutions, it end up that we will use CNC turning to make the crown and clip by casting. Both of these two production process are expensive, but turn out very good result on quality.

TWSBI Diamond Vacuum update 2010/11/14

這一個月的主要事情就是調整些細部尺寸,做小量產前的最後確認工作。
筆夾本來是用成形方式,但表面一直不理想,可能要改用鍛造方式,樣品試做中。
筆蛇模具還在開發中,要到十二月底才會試模,之後才能去德國買筆尖,看來有得等了。
我自己先裝了一支起來用,還是18K金尖的喔。
This passing month mainly working on fine tune final dimensions, get ready for small batch run.
The clip was planning be made by die casting, but we still not happy with the surface finish, so it may be changed to be made by forming. The sample is being processed.
This time we are going to make feeder and feeder housing by ourselves, the tooling won't be ready for test until end of Dec., then I can buy the nib from Bock. It will be some times to wait.
I made a pen for myself for testing, it has real 18K gold nib, cost me a futune to get this nib.

Twsbi Diamond 530 With Gold Nib

Yesterday I got quotation from Bock the 14K gold nib for TWSBI Diamond 530. one in single gold color another in two tone colors.
My cost plus the distribution profit... the end user price will be clost to US$110 per nib for single color and US$130 per nib for two tone model.
Will this price ok? I need to collect at least 300 orders to buy the nibs from Bock.

I am thinking, since the gold nib will bring up the pen price, why not just make an high value version of the pen to make it complete. how about
1. pen with 14k gold nib (single color or two tone?)
2. pen with HIGH VOLUME ink capacity, about 40% more ink
3. pen with aluminium piston mechanism
4. pen with solid brass clip (not the existing stamping parts)
5. pen with improved cap thread for smooth thread in and out
6. pen with metal parts plated with 14K gold or rose gold
Due to the increase in cost, the retail price will go up to about US$280. I don't know if this be fine. I need your comments.

To proceed with the project, I need to collect at least 300 orders. please leave comments in the thread.
If you like to pre-order, write me at speedy@twsbi.com. leave me your name, email, address, want nib (size) or complete pen.
you don't need to pay me anything until pen comes out.

Let me have your comment, see if we can keep the ball rolling.
