Haven't had much time the last few days.
Had some time yesterday afternoon and got the driver holes cut, access panels cut / fitted, and bottom panel glued in on the 3 Ghorns:
Cutting out hatches:
After routing the dado / rounding edges, perfect fit!:
Coming together: Notice how the cabinet makes the LMS 5400 look normal sized.....
Access hatch installed. Still need to put bolts.
Need to do bracing and get the driver panels installed.
