This is in relation to me building a bike trailer. I've got my metal plate that I intend to make drop outs from and need to drill a hole and then turn it into a slot for my dropouts. I just measured my drop outs on my mt bike and it is 1cm wide. This is america and I seriously doubt I will be able to buy a 1 cm drill bit. 3/8 however is .95 cm's. A measley .5mm away. Should this work?
Thanks,
Scott
