A very nice rack project for those so inclined

As they say behind the backstop at baseball games, "Good eye!  Good eye!".

Of course, just exactly why someone would impale themselves on this beast as a build project is beyond.  Particularly when far superior (and MUCH smaller) equivalents can be had 2nd hand for less than what the chips alone would cost.

But, that caveat aside, I always enjoy learning how different manufacturers had tackled particular objectives, and the sorts of performance features they thought would be useful.  So, thanks!
