Turning a triple into a double

I run a compact triple crankset on my cyclocross bike without the small
chainring. I can run smaller gears and have plenty of choices of chainrings.
I currently run a 36/46 in the front. I run a different BB length. You often
can run the crank closer to the frame due to no inner chainring. I use
standard double front derailleur and shifters w/ no problems. The only
problem for me is no chainrings larger than 46t but that's no problem for
CX. You shouldn't have any probs no matter what the bolt pattern is by
skipping the inner chainring, or outer for that matter.

I'd like to take the third chainring off of the cranks that came with a
used
bike I just bought to run a typical double. I'm assuming this is fine to
do,
and then adjust the limit screws on the front derailleur.

Anything else I need to do, or pitfalls to watch for?

Thanks.

In a word, no.

Don't even worry about chainline. I got a used schwinn paramount p-15
in high school and took off the granny ring so i would look "racey" in
the oh-so-flat midwest.

Nope, nothing but what you mentioned but gotta ask why? That small ring
doesn't hurt anything by being there...just a looks type thing.

Why bother? Just dont use the chainring you don't want.

Please dont tell me you want to save the weight of a chainring. If you
can change your performance by shaving off that kind of miniscule
weight, sponsors should be buying all of your gear for you.

Not a weight issue, and not an appearance issue. I have always used
doubles, and it's what I'm used to. Wanted to know the technical
implications.

Thanks.

I've seen threads like this, but I don't understand the need to go from
three to two rings either, unless it is just a personal preference sort
of thing.

If it serves no purpose (the third chainring), then its continued
presence on the bike is an Ethical Dilemma. It forms an Inconsistent
Heirarchy whereby the Man-Machine Nexus is rendered suboptimal.

In a word, the third chainring is: FUGLY

I knew there was a good explanation. Never expected it to be so eloquent.

You can also get a bottom bracket 5-6 mm narrower.
