How attractive are you and your substrate

[Waspjr (Travis)]

Simple quick comparison for sandbox base and thickness
First pic is 3mm door skin
Second is 5.2 mm door skin
Last is 4.5mm extruder acrylic ( ask me how I now know it’s extruded , reference the crazed background lol must be mindful of expansion and hole diameter)

I really should have done a comparison with a set distance as most of my equipment maxes out at 10
And extra dad points if you instants thought this was a stud finder post.

I just grabbed a piece of scrap Luan that was mostly flattish and cut off the parts that had black spots.

It was 1/8ishy based on my high precision thumb and finger gauge.

As for me … pretty much the same

Hope that helps!

I used 3mm base plate and just stacked enough magnet to grab and move the ball like I wanted
