I bought a Novara 29er that came with Presta valved tubes. After I got my first flat, I decided convert the rims to Schrader so I could use Slime. I know you can get Presta tubes with Slime, but the valve tends to clog up.
I inserted the reamer in an existing Schrader rim and used some tape to mark how far I needed to go.
Working carefully, I reamed out the valve stem holes on both wheels. Then I used a rat-tail file to smooth out the openings and installed Schrader tubes.
Using a reamer is better than drilling since you can go slowly. Hopefully it will be along time until the next flat.
