Sucking it up for science

 

Everyone else has stellar luck with their TWSBI 530s, 540s, and Ecos. For reasons known only to the Cosmos, I have not fared as well. Lions and lemons are not a typical pairing, but I somehow ended up with Mufasa’s share of a Meyer orchard. So I ditched every TWSBI I had and promised never to be lured by the Taiwanese mark again.

 

Enter KWZ’s iron gall ink. The maker told me that he uses his IG formula in a variety of stainless nibs to include (drum roll, please) TWSBIs. Now I have several Franklin-Christoph nibs in High Performance Stainless but I wasn’t about to risk them on impulse. So while killing some time at the mall, I discovered a workable formula:

 

            B&M Discount Coupon + TWSBI Vac 700 EF = Test Mule

 

The plan was to fill the pen with KWZ Gummiberry for six weeks, then resell the pen after the test and recover a chunk of my investment.

The main players in this experiment. Will it work?
I filled the pen, not bothering to flush the guts clean of any oil or residue. The first few days validated the 700’s rep as a dry writer, but she settled in quickly. I thought the ink would stall in a nib this fine and arid, but it never did. I left the pen unused for a week, and it started the moment I wrote with it. I let it rest for another ten days, and it still wrote when asked. The ink may have had a lot to do with this, but I could not discount the contributions of the JoWo feed and nib.

 

Intrigued, I decided to place it in rotation. The 700’s handling is good. The step from barrel to section is pronounced but not uncomfortable. When the tank is filled to the brim, the balance point hovers above the web of my hand. I’ve never felt the pen to be back-heavy but then again, I don’t post.

It’s not much bigger than some popular small pens. But it is big enough. 
When the time came to refill, I rinsed the Vac with clean water. I pulled the nib and scrubbed the feed with some toothpaste. No inky muck was found so I figured the ink was as friendly as an IG can be. After loading up, I noticed that the flow improved noticeably and lines are now closer to what I expect a Western EF to lay down.

Everything rinsed clean. That haze on the piston is just water.

And none of the shiny bits were hurt in the making of this picture…
As the weeks passed, I kept tabs on all the shiny bits. No corrosion or pitting formed, not even on the section trim ring. The plunger shaft did not lose its polish, and I detected no precipitates or residue forming anywhere within the tank. When I terminated the test, I took the pen apart, rinsed it clean and again, found no incriminating sludge or crud. I loaded up with Herbin’s Poussiere de Lune and the Vac ticked like a Timex.

I figure this 700 will stay with me for a while.
