Hi Fellas,
Tim, we did not come to a conclusion at the cooler! We do seem to have a full range of opinions, though...
I'm the drawborer in our group, and when I do so, I poke the tenon, dissassemble the joint and re-dill. Gabel, I have been doing so for many frames now with sawn and turned pins with good success. Ken, we also pin center tenons on fairly large members with good success (and I DB them).
Our frames our generally cut from standing dead timber, through pegged, with a drill guide.
And what about offseting your hole by angling the drill with the joint assembled? Do you guys feel this is effective?
