FPR ultraflex on a TWSBI ECO

[ambling_around]

There seems to be a simple way to get #5.5 FPR ultraflex nibs to fit snugly in the ECO, and get a nice flow without an overfeed. Bonus unlike an aluminum overfeed, it never rusts. I align the nib and feed and wrap them together with about 1" length of plumbers Teflon tape. Be sure to keep the tape below the nib shoulders or the tines can't open. The nib and feed now fit snugly into the grip even though the interior of the ECO grip isn't perfectly circular. And it keeps the nib underside in constant contact with the feed creating a steady flow of ink. Works equally well with #5.5 FPR ultraflex on the TWSBI 580 and with #6 FPR ultraflex on Noodlers Ahabs. Ditto with a couple of #5 and #6 Jinhao fude nibs.
