Thank you! I have high hopes for this tank. I've been thinking about using one of these stands for years, it wasn't until recently I figured out to put a concrete top on it so I could use smaller tanks.
Here are some pictures I just took of the magnets.
I used wood glue to attach a few small pieces of scrap to the wooden panels I added. I then drilled holes and epoxied in some rare earth magnets:
On the door panel I drilled holes and epoxied in opposing magnets:
When you close the panel in place the magnets on the doors line up with the magnets in the stand:
In order to know where to drill holes on the door I first installed the magnets on the side panels, then put a little ball of painters tape on the magnet. Then I shmooshed the door on. The painters tape stuck to the door panel in the spot I needed to drill to get the magnets to line up. Theres a few different ways to do this including using a dab of paint etc.
