The trunnion plans call for multiple layers glued up in a sandwich to leave an open slot that the locking bolts can move around in.
I used the table saw to cut up some more of that maple bed frame I dug out of the trash last month. I cut it to the proper thickness and took some off each side so I can remove the finish as I get down to the proper dimension.
I marked out the upper and lower curves of the trunnions using a compass set to a different radius for each curve.
And then I cut each one out on the band saw! This saw is working great!
