Any stories of success?  I _just_ fired up my M-200 and on the top,
the second roller looks good and firm but not hardened.  The first
roller is getting gummy and is not to be trusted.  It's not shedding
onto cards but that will assuredly change.  I've been reading about
the procedure to remove the block the capstans are mounted to.  I see
they want a guide shim made from a stack of cards (5? 7?) cut to a
certain size (2"x5", I think).  In the day, it would have been easy to
score blank or discarded used cards and make a stack.  Today, I might
consider making an alignment shim from index cards and measure the
total thickness rather than cut up punched cards.

I looked into that - I'm sure the results are of excellent quality,
but he appears to want $35 per roller and $5 shipping per order.
There are 4 capstans so that's close to $150 USD.  I'd rather find a
solution in the $50 range.
