Bridgeport Mill J1 Rebuild
made to fit the way surfaces and milled the surface to remove most of the defects. I still have
some small drill marks, but these do not adversely affect the accuracy of the surface.
6.3.3 Table Reassembly
Table reassembly follows the reverse order of disassembly. You begin by ensuring that all way
surfaces are free of debris and lubricated with quality way oil. Before attempting to install the
table, you should ensure that the table locks are fully withdrawn, and the gibs are removed. You
can now maneuver the table onto the saddle by aligning the dovetails and sliding it onto the
saddle. You should install the gib next and loosely secure it before you remove you lifting device
from the table. If your ways are extremely well done, it is possible for this table to slide because
of its own weight. The bearing brackets are then installed along with the dials and handles.
You should reinstall any lubrication recovery systems, and automatic oilers.
Complete the assembly by installing the power feed if equipped, and the power feed trip levers
and rods. Finally you should check the table for movement and adjust the gib based on the
procedures described in section 6.2.3
If there is enough interest, I will be converting this mill to automatic oiling and will document
this procedure as well. It could just become an appendix to this manual.
