I had a machinist drill my 180 cranks for just such
an application. If you check out
http://home.ix.netcom.com/~santana/ and look at my
MASI, you will see just the modification you are
talking about. I chose the 74mm bolt pattern just so
I could get a 28 chainring installed. A 36 seems
like a waste of a triple. My NR derailleur (or
Record or whatever) shifts the chain just fine. The
small chainring is actually made by Specialized. I
had to drill out the mounting holes so it would fit
on the sholder of the bolts. It looks like a small
Super Record chainring.
Does anyone have a sorce for the Campy chainring
bolts that thread into the cranks? I only have 1
set, and am using them. I need to get at least two
more sets. I could get you the exact Campy part
numbers from cataloge 17.
