Did you notice the precision placed holes along all the edges? Just right for locating and anchoring 8020 aluminum on which to mount rails all laid out on a perfectly flat surface.
I hope I didn't hurt his feelings when I snatched it and ran!
(Just kidding, I'm on oxygen 24x7 and I DO NOT RUN! ANYWHERE! ANYTIME!)
After much butt scratching and delaying I finally ordered the rail, 1X3 8020 and some .625" ball screws and nuts just to round out the project. Might just as well build some speed and accuracy while I'm at it.
Here are a few shots of the cabinet after stripping the old mechanics off and one with the plate in place.
I chucked up a piece of round plastic and drilled it for the quarter inch bolts I'll use to hold the 8020 down and turned it to a snug fit it those step drilled hloes in the plate.
I dropped bolts into the holes to make them show up in the photo.
