I am attempting to recreate ornamental brackets that were installed on my porch. The house in built in New England at around 1914. The brackets appear to have reoccurring patterns. I recognize some basic shapes, and I would like to figure out how the original craftsman laid out the bracket so they could be produced in batches. There are at least a dozen, and they are fairly roughly made, it looks like the hand of a carpenter (as opposed to a journeyman cabinet maker, or furniture maker).
I have watched Roy Underhill's The Woodwright Shop, and I recall an episode where Roy used simple dividers to layout impressive details on a chest of some kind. I also recall a different episode where his guest produced remarkable beading and decorative edging using similar techniques.
The dimensions are 16 inches by 16 inches, cut from 3/4-inch stock, and fitted with (5) ~1/2-inch diameter spindles.
