Sheet Metal on Peg Board
Cut a piece of sheet metal into a 9-1/2 inch square and use spray
adhesive to glue it to the peg board and duct tape the sides. I
rounded off the sheet metal corners so that the screws going down
through the brackets don't touch the sheet metal and cause a short.
On the top left of the picture is a white wire, this is the ground
wire from the controller that is soldered to the corner of the 9-1/2
inch square piece of sheet metal. The brown stuff around the sides
is high density weatherstripping. The white triangles in the corners
are foam core, 3/16 of an inch thick. If you can't find foam core
you could probably cut up an old mouse pad for the triangles. The
foam core and weatherstripping will hold up a lucite panel with
sheet metal. Make 4 of these peg board panels for the UP, DOWN,
LEFT and RIGHT arrows. To cut down sheet metal costs, instead of
a perfect 9-1/2 inch square you can make it 9-1/2 inches by 9 inches.
To make the arrows more sensitive, I cut two 1/2 inch gaps
the weatherstripping along all four sides. The arrows feel less spongy
and the gaps let air trapped in between the lucite panels escape. For
a picture, look at the diagram where it says Bottom Half of Arrow
Also, don't use aluminum sheet metal, the solder won't stick to it. Us
Use 26 gauge zinc stainless steel sheet or sheet metal that says
plated steel sheet. The sheet metal will look like it has spreckles on it.
