Hello David B,
For the sake of this discussion and what you just shared, I must also share once more that 90% or more of all bracing in traditional timber frames work only in compression, and any "tension" effect is from "binding." In the last 5 years we have collectively seen, taken apart, removed, and/or site surveyed hundreds of barns in Southern Illinois, Indiana and Ohio (among other places) a conservative 1/2 of all brace pegs are in failure of comprised due to lack of relish. The reason that pegging evolved in those regions was for exactly the reason that Tim, et al, have shared...ease and facilitation of raising. These pegs do little if any work in climate or seismic events. They do tend to keep the brace "in play," where others fall out, however, even with the pegging, many braces still dislodge due to complete peg and tenon failure.
Regards,
jay
