Bearing Press Bottom bracket and linkages

You need an 8mm rod. this can be threaded into the body, in that case it will wear out the plastic eventually. i ended up heating it and gluing it into the tool body. 
You need an axial bearing (51103) to get the most out of the rotational stop. but its has worked without as well. (Just adds extra torque. )

The handle is completely optional and prone to breaking, but i liked it for low pressure on small bearings.
