Technika cameras are precision made and you are best off buying original Technika made lens boards for these cameras. A lot of the aftermarket lens boards won't work with a Technika camera.

Tachiharas and Shen Hao's have more slop built in them and will take the aftermarket Technika style lens boards. I own a Tachihara and have purchased aftermarket new lens boards from Badger Graphics and used lens boards off Ebay and have never had a problem with fit.

To answer your question, I don't know why it wouldn't work on a Tachihara and if it doesn't fit a Tachihara then what does it fit?
