[Harp-L] Re: Microfiche Reader



When viewing a reed in a microfiche reader, I was able to obtain the
clearest image by giving the reed a zero offset.  While examining vintage
reeds at Hohner in the '90s toward improving reed tooling, I placed a thin
strip of cellophane tape near the tip of the reed to give it a zero offset,
thereby avoiding having to permanently alter the reed's offset.

Here's a link to one of the photos I took during that project:

Best regards,
