We can thank this thread to a bout of heartburn in the middle of the night.
I put together a bunch of wierd things to for a trials set up. It’s made up of a cross section of a large tree that was then cut in half found outside a church at the curb, a large black wooden box that had an old TV on it when I was a kid, a surplus student desk, a pilfered pallet, a car ramp and two 3" x 5" 's of wood scavenged from the pergola we took apart in front of the house a year ago.
