Without a pilot hole that is through both surfaces, how did u ensure the drilling from both sides will meet and align in the middle perfectly?
If the entire length of the hole is not tapped/threaded, how did the male threaded end of your connector go through the hole?
The acrylic lid is only 3/8” thick. The step drill bit will be through the other end way before you get to 7/16”.
The tap is way longer than the thickness of the acrylic. I tapped the whole hole, but wanted to make sure the taper from
was not too much I didn’t get a snug fit.
