How do you "work it the other way" and make the valve hole smaller?
Is there an adapter ?

Yup.

Probably available at your lbs as well. (I've also seen them in brass
once or twice.)


I actually don't use the adapter. What I meant was I drill for Schrader on
my MTB rims so that I have the most common tube (for MTB) as an option in
the event I need to borrow a spare. I run presta on both the road and MTB
bikes. The OP I think wants to run all Schrader and drill as such, I run
all presta but drill for Schrader so I have more options. I think the
adapter is probably more warranted on the road setup as opposed to MTB
because of the higher pressures. I've never had a problem with the MTB
setup with presta in Schrader holes at my usual 50 psi or so. I've always
left my road rims as presta. Actually, the whole presta-only thing for me
came about because I'm too much of a lazy-ass to change the chuck in my pump
every so often! How sad is that?!?!
