Shimming out Campy 10 driveside dropout - possible/good idea?

Since 2001, over 90,000 cyclist's have joined Cycling Forums to discuss topics from general cycling to equipment, training, racing and travel or vacation destinations (especially in europe during the tour de france). We also feature an great deals in our online store, 100's of articles, classifieds and product reviews.

When I drop into the small cog on the cassette my chain hits the
chainstay. Not good for the chain, probably not great for the
chainstay. The amount of extra clearance necessary appears to be <1
mm.

I was wondering if a washer could be placed to push out the chainstay
relative to the cassette, thereby creating the extra clearance?

Could a washer be placed between the freehub nut (part p in Fig. 1 of
the Campy rear hub manual) and the axle?

Any other suggestions other than taking a grinder to the offending
weld?

TIA

My other suggestion would be checking the chainline. Had a similar
problem with Centaur 10 and turned out the chainline was too far to
the right.

Other consideration could be switching to a smaller/larger sprocket to
get the chain clear the dropout/chainstay. I wouldn't grind the weld,
but a spacer could do the trick too.
