I had to make some copies of existing brackets that were damaged on a historic home in the Irish Chanel in New Orleans. I made them out of spanish cedar to resist moisture and cut them out on a scroll saw.
The black stripes help me remember what is to be cut out.
scroll saws are perfect for bracket work because, unlike a band saw, you can detach the blade and thread it thru a hole to make isolated cuts in the center of a block.
once you have a good drawing to work from, all you need is transfer paper to copy the design onto wood.
The cutoffs all look like sea serpents to me.
I made three. Important that they all match!
