Help! Trying to build up my new frame, first time I've done this and I've inevitably stumbled upon my first problem!
I'm trying to install my Shimano external BB, drive side went in a treat by hand and tightened up with the tool. Opposite side however will only go in about 1 turn before it gets stuck. I'm scared to get the tool on it as it may knacker the threads.
Any tricks to help it in or do I need to visit my LBS?
