N00b Question Time. :( Rim Drilling.


Recommended Posts

do it like this:

Mark the mid line of the rim all the way round using a device as shown. Use the braking surface as a guide.

Now mark centres between spoke holes (watch your nuts) then centre punch all the way round.

Drill like this using a drill press. The sockets (should be of equal size but I couldn't be bothered to look for two the exact same) will ensure that the rim doesn't jiggle around and ensures that you are drilling square. Here I am drilling pilot holes. Go all the way round with the pilot drill and then with the desired size drill.

After you have read this, before you drill your rim, go and take your socks off and ride your bike. You will then have an idea of how much weight you will lose on your bike.

Or take a good dump.
