The existing LB (head box) has to be modified

The existing LB (head box) has to be modified so the connecting cable can comfortably connect to the board. The LBs are from different manufacturers and are in two basic styles one is made with rounded ends and the other is square ended. I decided to remove the square ended boxes and install rounded boxes at all locations as we go along replacing the old signals when they fail. Progress has been slowed because Richard likes to repair the old boards and not update them,

First the box has to be restored to its original depth so I use the radial arm saw in the shop to slice off the extension that was glued onto the box before.

Next the feed hole needs to be reamed at an angle using a Unibit to make it easier to connect the board and slide it into the head for use. I had moved the location of the connector on the circuit board in the final design to the rear side of the bottom of the board to minimize this need but it turns out that it is still necessary.
