Time for some more pics:
Front and rear facer boards glued on and ready to be trimmed.
Flush trimming, especially when there is a decent overhang to remove, makes one heck of a dusty mess. That's why I usually do it outside. Unfortunately the weather has been a bit brisk (OK so 4 degrees F is a little more than brisk) so I needed to come up with a way to do the trimming in the garage without creating a cloud of sawdust. This jig works very well. The main port by the bit is connected to a dust collector and the through port for the router is connected to a shop vac. Between the two 99% of the dust is captured.
Here is a cabinet after the flush trimming
Next I laid out where the openings were
Then drilled relief holes in the corners of each section
For the jigsaw
All openings rough cut with jigsaw
Now I had to flush trim the openings. Unfortunately the jig wouldn't work. for one thing, it was too small to span the openings and keep the router from tipping. I picked up a piece of phenolic board and made a large subbase for the router.
With the addition of a palm router with a pattern bit for one edge of the amp opening that did not have a sidewall I got all the openings cleaned up
I also got the grill frames cut out
I have also recently acquired a few, new to me, pieces of equipment. First is a Walker-Turner cabinet saw. Older than I am, solid as a tank, smooth running, quite and with enough torque to cleanly crosscut 8/4 walnut like butter with a full kerf blade.
