How to attach a 4x8 plywood to a air hockey table

Question

I have a 4x8 plywood with walls around the corners built using 2x4. It's very heavy. Kids are going to build structures using Lego on the plywood tabletop. I want to place the tabletop on top of something so kids can stand and work on it. I have a air hockey table approximately 3ft x 6ft that I am hoping to use by placing tabletop on it. One problem with this approach is tabletop can begin to slide and move around as kids lean on it. So the question is, how to affix tabletop to the air hockey table so the tabletop wouldnt move and when the season is over I can remove the tabletop and store it away. I thought of velcro stripes mot sure if they would be strong enough to attach. Are there other options ?

Answer 1

Add a skirt, e.g 3/4" plywood strips, to the bottom of the panel that is just large enough to surround the top of air hockey table to prevent sliding. It's a simple matter to lift the top off and set it aside.

Note that this assumes that the table is heavy enough and the kids light enough that playing on the maximum 1 foot of overhang will not cause the table to flip off the air hockey table. If that is not the case then you'll need a positive hold down of some sort to ensure that everything falls over together. That might be as simple as screw eyes on the corners of the skirt tied to the legs of the air hockey table.

Answer 2

EDIT: The answer now has a pic of the air hockey table. I've never seen one that's not rectangular. The shape of the table shouldn't really affect my answer other than the pic is less accurate--but the concept is the same.

HABO's edge idea is still better.

Velcro should be enough

I Do like HABO's idea, and it's unquestionably more comprehensive than velcro strips.

However, considering a 4x8 sheet of plywood's weight--I'd bet good money that velcro around the edges would be plenty enough to keep it in place.

In fact, I'd start with only around 6" of velcro at each corner, since velcro the full length may render the plywood extremely difficult to remove.

Of course, aligning the velcro is key to it working properly, and the velcro adhesive may damage the table's finish--then again a heavy sheet of wood won't exactly polish the table anyway. :,)

Something along these lines. In this example, the black is the velcro.
