I can make use of them though, in my trestle. The trestle has about 2/3 of it’s length on a curve .. consisting of approximately 3″ long segments. Where the join is a probable week point. Corbels can reinforce these joints .. and what the heck .. they look cool tool.
There’s no set size. –
Note: Bolts run through the corbel up through the stringer and through the ties .. one on either side of the rail. The corbel is the width from the outside on one stringer to the outside of the other.
My stringers are similar to those in Fig 76 being a pair. the width is .270″ or about 13″ in width. I have some strip-wood measuring 3/16″ x 1/4″ – equating to a 9″ x 12″ corbel. That should suffice. I need a total of 10 corbels, each 1″ (4ft) long and notched 1″ or so.
