"I assume you are trying to use the magnets to somehow clamp the acrylic. It may just be a case of not enough clamp load to hold the pieces together tight enough."
Right. I just want to hold them together and keep them from slipping relative to each other. Strongly enough that I can position...
I need to hold two small bars of acrylic (1 x 5 x 1/4) in alignment. I can only put the magnets into the large flat surfaces, between the bars. I have used 1/32 x 1/4 neodymium disks, and they work fine against lifting one bar off the other. But the bars can slide, one over the other.
Is it...
