I knew not everyone would agree with me, but hey, it'd be a boring world if we all agreed all the time :D
Robyn, I'm using a micrometer to make sure the holes are lined up perfectly & I'll use a drill press to ensure accuracy.
Longjohn, it's not just enlarging the holes, I wish it were that simple.
Vintagemore2000, the P-33 & P-86 are both mechanically superior to the stock parts, I've wrestled with the P-32s for many years, trying to get those %#@& flathead machine screws to tighten enough without stripping the heads.
I have a '59 Downbeat in Black Galaxy (very rare as y'all know) & all I've ever done to it is lightly hand sand the bearing edges, pack the lugs, repaint the BD hoops & I've replaced some of the hardware (spurs, tom holder, FT legs) with the new A.T.L.A.S. stuff, which requires no drilling & I've kept the original hardware. The new stuff makes the set more user-friendly.
Now my '68 Big Beat is another story :D I started tweaking it long before vintage drums were a thing, it's on it's 3rd finish (originally blue sparkle, not particularly rare) & I converted a '70 10x7 concert tom to double heads for it. It sounds wonderful.
Thanks to everybody for their input.
