This is the fifth and last project for Open Door Escape Games, which is for their scary themed game called "The Trials". My son-in-law Matt made this hex tower out of 3/4"plywood and glued it together. The slots and the pieces in them he made as well.
 

However, once Matt was through cutting all the slots, this ended up weakening the structure because of how large and long the slots ended up. So he wanted to add some strength to this tower which is what this final project will consist of.

What I'll be making is some steel hexagon pieces that will slide over the tower, which will be placed between each slot and screwed into the wood. There will also be a piece that will go on top that will add strength and act as a trim piece. So lets get started.
 

I'm going to work on the top trim piece first using some angle iron that came from a bed frame. I'll cut six pieces, weld then together and then grind and paint it. Also notice the holes in the material, I'll have to make sure each piece doesn't have any holes so I'll have to work around them as I cut my pieces. 
 

Here is what I had on the backside of the angle that was hard to see in the picture above. I used a large piece of solid bar stock on top of a slightly smaller piece resting under it (arrows). The reason I'm using the smaller piece is because there is a 1/8" radius on the angle iron and I didn't want the larger piece of bar stock to be hindered by it. So by putting the smaller piece under the larger piece, this clears the radius on the angle iron and keeps the work piece clamped like it was a solid piece now.
