All kinds of great and wonderful stuff buried in various trays and cabinets. First stop for stainless #4 hardware.
Thanks for the nice remarks Jake.
I first lay out a pattern on the FPE software. I set all the holes to 1.5mm, the panel to 'clear', and print it out. Then I tape it to the panel and use a
center punch to dimple the panel. I leave the paper on and use a pin vise to start each hole, using three sizes of bits. Once that's all done, I remove
the paper and fire up the drill press. I start with a small bit, working my way up to the desired size. I finish up each hole with a hand held countersink
tool I got at Harbor Freight. The real pain doing anodized panels are what I call 'spinners'; the shavings that can scratch circles in the finish. The process
is painstaking enough as it is, but having to stop each 'plunge' 4 or 5 times to clear them is really a pain in the patootie. BTW, the pattern on this amp
started out as concentric circles, and, uh, got a little out of hand. :-)
Amen to your Ace endorsment. I also use the stainless #4 stuff. I also like to use M4 screws for the Hammond panels, as the #6 stuff, to me, is too
easy to strip.

nice drilling job, it looks painful to do.
Yes, you're right. I'm noticing it with the HD600's as well, just way more noticeable with the D7000's. Of course, it's only when I'm touching the amp, so it's
not a major deal. I'm thinking of ordering a couple of 8416's, so that would fix the problem (I hope). BTW, does anyone here know of a good source for them?
I see Tube Depot has them. Just wondering if there might be a better, read cheaper source.
