I modified a HP 9825A tape drive for use with QIC 40/80 tapes.
It's a rather easy conversion building a new capstand wheel witch is a
little higher so it can drive the QIC tapes and increasing the write current
by replacing a the current limiter resistor.
It's under test and at the moment seems to work.
I was curious if there others who did the same and what theire experiances
are...

Interesting, Rik. What did you use to build the new capstan?

For the prototype I glued a small clilinder of polycabonate on top of the
capstand.
I used a poly-urethane glue for it.
After customizing the capstand I fitted a small piece of rubber hose on it
(I use 6.5 mm hydraulic hose for Citroen LHM systems also glued with
poly-urethane glue ) the next step is grinding the capstand to the right
size on a small lathe.
I'll put some pictures on flickr this week.

I've never tried any such modifications, but if you can poit me at
details I might well give them a go. I wonder if the HP9815 can be
modified the same way (it's the save drive and head switch/amplifier
PCB, buit with a totally different controller).
