Another 9 double to 10 triple question

Quoted message said:

I have sucessfully changed my Ultegra 6500 double to a blend of 6503
and 6603 components.

Crank set and FD are 6300 while Rear is a 6503 RD with a 12-27 9 speed
cluster.

Would I be better off using a 10 speed chain and if not, is there a
chance of damaging the 10 speed chain rings with a 9 speed chain.

Another dumb question..how do I increase the Jockey pully tension.
There is almost no clearance above the cluster.

If the crankset is a 10-speed version, you should use the 10-speed chain. So
says Shimano, and so says our own testing, where we used 9-speed chains and
found they created one heck of a racket (very noisy plus didn't shift as
well). The downside is that 10-speed chains don't last as long.

For more clearance above the upper jockey wheel, you need to tighten the "b
tension screw" at the back of the rear derailleur.

I would have guessed that shifting to larger rings with the 9sp chain
would have been better. Those bellies that stick out would hit the
shift assist pins better. I guessed wrong!

Always match the chain to the cluster-In your case, 9s and 9s..You will
not damage anything by mixing chain widths and chainrings.

If no clearance above the cluster, if I understand this, need to screw
in the b limit screw all the way and if this doesn't keep the pulley
from hitting the largest cogs, shorten the chain.

use a 10s chain on a 9s cluster and shifter?-Don't agree and I have
installed 10s cranks, both double and triple with a 9s chaion w/o any
noise.

Which 10s cranks? These were FSA, with the new 10s (10-speed
Shimano-specific) chainrings. Don't know how it would have sounded with the
10c (works with Shimano 9 or Campy 10) chainrings, nor have I tried the
experiment with a Shimano crank. But on the crank in question, there was
quite a rattle with the 9-speed chain, and market silence with the 10-speed
version. The difference was not subtle.

Guess I don't get it then. When Campagnolo specific 9/10s FSA cranks
were nowhere to be found, we bought the 'S-10" version and mounted them
on everything from 8s setups to 9s setups to Campagnolo 10s setups w/o
any problems, issues or noise.shimano 9s chains, Sram 8s and 9s chains,
No noise, problems in shifting, nuthin.

I think I had a set of Campy specific FSA cranks. The requisite
bottom bracket was the 102 ISO. The letters "ISO" were stamped on the
inner face of the crank near the square taper hole. The rest of the
cranks looked identical to the other taper cranks. I was told that
'some' of the ISO ones were made early on. I don't know if any were
Compact cranks.

The local LBS told me that the chain would be split apart if run on a
9 speed cluster. Seems to be plenty of wiggle room and the 9 speed
chain rattles.

I bought a 10 speed Wipperman but they would not take respponsibility
if the sides pulled apart???

The B screw is all the way in. I'll play with chain length.

Hopefully I'll do my climbs in 15 or so years this weekend in the
Santa Cruz Mountains.

Thanks!

The chain will not self desctruct on 9sp cogs. Campy 10 sp cogs are
same width as 9sp. Shimano chain is same width at the pins and
material has been taken off the sideplates, mainly the buldges on the
outside. I run Shimano 9 frequently on my Campy 10 system with a 10
sp chain w/o incident in over a year.
