1) I've searched and checked the project announcements - hope you guys can help.
Many cabinets have an administrative panel which is 3" to 4" higher than the control panel. These panels are usually flush mounted with the sides. Do you usually run the T molding down below the control panel / box. The reason why I am asking is with a T molding wrapped CP top against the T molding going past the administrative panel and CP box for the sides - Don't you end up with a gap?
I'm not really sure I understand this question, Like Locke said, do you have an example pic of what you're asking about?
2) I'm planning on using a keyboard drawer. These are usually designed as just a drawer front and a drawer base. I assume this is because the wood battens attached under the CP box would block a regular drawer. There must be a reason why builders aren't attaching their CP boxes directly to the 3/4" sides with inserts or screws rather than wood battens under the CP box. This would allow for a regular drawer with sides for extra storage. What am I missing? Cheers
Generally speaking, it's difficult to put screws edge on into MDF or Ply without destroying the edge. So the strips are generally used to take advantage of multiple points of bond to take advantage of the strengths of MDF or Ply. There are a few cabs that don't use them or minimize their use but the designs or the choice of wood is the factor here.
The drawers tend to lack sides because the the drawer turns into a shelf when it opens. The front should move out of the way to allow the drawer to come out and turn into a shelf for the keyboard. Personally, I completely eschew keyboard drawers in every cab I own. I see no reason to spend time and money designing for a keyboard that will only ever be used during configuration and will be left inside, largely untouched, for the entire life of the cab. It's too much investment for very little return.
If you've got a real boner for a keyboard. A better design might be a lift up CP with a small shelf for a keyboard inside or a small dinner tray style skirt that you can fold up for the keyboard. The first option is something you're going to do anyways to access the wiring for the CP controls, the later option would see more use such as a shelf to hold beer or chips and dip during parties.
Or you can do what I do. Just have one (or two) spare keyboards and if I need it for configuration, plug it in.
