Hi guys,
My progress has been slowed a bit due to a quick refresh of our master bedroom. You know the story, bought new bedroom furniture so we probably ought to replace the carpet, and if we are going to do that we really should paint the walls, but the walls look like crap so I should fix up the cracks and holes and then retexture...
I have managed to keep things moving a little though. Tammy stained and varnished my 1/4" birch veneer plywood panels, they turned out great. I hope I don't screw them up (she'd kill me).
All the MDF panels are cut to size, my router bits showed up (www. pricecutter.com has good router bit prices BTW). I ordered a 1/4" spiral downcut bit and a 45 degree chamfer bit with a 1-1/8" cutting length (for my 3/4" x 3/4" chamfers). My updated cross-over bits (w/ Sonicaps) showed up from Danny. I also received my digital camera, so including pictures should be easier.
Which brings me to my question for you guys. As I think I mentioned somewhere previously, I plan on doing external cross-overs. I also have sufficient terminals to allow for bi-amping/wiring all the way through. So, I have 12 sets of Danny's heavy brass speaker terminals. I want to have the terminals popping straight from the back of the box(es). Preferably, no plastic spacers or plugs showing. Like this from Darren's gallery:

But... the terminals I got from Danny have a plastic spacers with them. See here:

No problem I thought I don't really need the spacers, or do I? As you can see below the back sides of the brass terminals have flats cut in them that are keyed to the plastic spacers.

I don't have a bit for cutting a hole like that...

Basically, there is not regular/round shoulder on the backside of the terminals. So unless I'm a dingbat (entirely possible) it would seem that I'd end up having to drill holes for the size of the threaded part and just end up w/ the two undercuts sitting out there in the open (gasp). Akin to this:

Or, the plastic spacers on the outside of my boxes.
Suggestions anyone?
