OK - here we go. The photos aren’t the best since I didn’t feel like taking everything off of it and taking it out of my storage unit (I live in downtown Boston… pardon my tack hoarding).

Front view. The board and the bridle “hooks” are pine and from Michael’s. They are surprisingly sturdy- this is going on 3 years old. I don’t remember what the board cost but it wasn’t much and the “hooks” were a buck each!

Back of board
The hardware including the brass martingale hooks are from Home Depot.
Supplies:
Wood board
3 bridle boxes
Two brass hooks
Two screw eyes
Two double ended snaps
Wood glue
Small brass screw (I forget exact size, but maybe 1/4-1/2" long and a fairly small width)
Measure three places for your bridle boxes and measure for brass hooks (I did the hook measurement by centering off the box measurements). Remember the boxes have some width to them so you will be well served to mark where you want the edges of the boxes to line up on the board as well as the center.
Use wood glue to get boxes on board. Let dry until stable - doesn’t need to be fully set - maybe 5-10 minutes.
Using a drill, install three screws through back of each box to anchor to board.
Use the drill to install the hooks (I didn’t find a need to wood glue these first).
Find the center of the board and measure from here to mark where your screw eyes should go.
Use drill to start the screw eye holes (be sure to drill straight) and then install by twisting manually.
Throw it up with some double ended snaps.
Voila!
I imagine this would look much nicer if it were stained and poly’d but this one doesn’t travel much, so it works as is. Let me know of any questions and happy building.
At shows, you can use zip ties, ropes, etc instead of the double end snaps.
