Hi Lumber Jocks,

I’m fairly new to woodworking and have a project to make 16 plywood pedestals for an exhibition. I’m going to be making it out of birch ply and there can’t be any visible fasteners. They are fine with a butt joint and want it to be as cheap as possible.

Would a glued butt joint be feasible/strong enough? Should I use brackets? Not sure what would be an easy way to make these and any input would be greatly appreciated.

THANKS :)

Do you have a sketch of the design to give a rough idea of the shape and size? What will be sitting on the display pedestal?

The butt joint is the weakest joint there is and depending on the size of the pieces(bigger is not good) without any type of mechanical fasteners,(screws,nails,bolts ,brackets) the glue joints will fail under the slightest bit of stress

Hi guys, thanks for the responses. The pedestals will be 10” x 10” x 40”. I’m thinking of using 3/4” birch ply. Not exactly sure what amount of weight will be in them. I can make a sketch tomorrow morning to demonstrate.

Some food for thought…

You will need either a router table and bit or table saw with dado blade.

Rabbets or biscuits and glue will work fine.
Pocket hole screws would work fine.

I’m waiting for the sketch.

In the mean time cheap and no visible fasteners =butt joints with tapered plugs cut off and sanded smooth.
For a more refined product I’d use biscuits or better yet domino’s.

At this point there been no mention of plywood edge grain showing so the above could change depending.

The better information given the better the chance of getting better answers.

I would edge band it, a roll of that stuff is cheap and looks good and use pocket screws, strong and hidden, cheap and easy to do.

Pocket holes or biscuits would be the best and cheapest joints.

I also wonder how he plans to finish these. He didn’t say anything on finishing either.

No visible fasteners, but visible plywood edge is OK? Must be for an artist
