New to the forum and this will be my first timber frame project, and I'm looking for a little advice. I guess you'd call it an arbor, over a small 12'x12' second story deck. Material is nominal 4x stock, so 3.5in, top beam is a 4x6 and the ribs are steam bent and laminated 4x4s.
I've already got the uprights lagged and bolted in place, had to do that to get the siding around them. This looks like a good place to ask a few questions, an hopefully get some additional wisdom about avoiding any pitfalls I don't see. Happy to provide any more drawings or info, but here goes the initial questions:
A) is it reasonable to tenon the uprights in place with a circular saw, set to depth, and a chisel?
B) what's the most reasonable tool purchase to get the mortising done, plunge router?
C) the birds beak seemed like the most reasonable way to join the ribs, but is there a clean way I could extend the ribs out past the cap beams.
D) any suggestions for an unobtrusive tension member to keep the rib from wanting to spread under load out at the end (there's not going to be that much load though).
