I would like to hear your opinions about pegging and wedging the king post/tie beam joint and pegging at other than 90 degrees? Thanks.

Other than ninety ? Need more information to provide useful feedback.

What are you building and what is the cause of the pegging issue ?

Other than ninety degrees to the face of the tie beam! I am building a king post truss, 28' span. Second floor loft. I am curious because have seen a few different examples of pegging and wedging at the king post/tie. thanks

Still not seeing it Trimber -

You can peg at 90...

And wedge in line with the tenon.

What are you asking after ?

28' is more than do-able, provided proper planning.

Trimber,

I can see at least one situation where you would not use pegs driven at a nominal 90 degrees from the face and that would be where lap joiney is employed. Oft times, especially with cruck framing two pegs will be driven at differing and equally opposite angles to help lock the lap faces together and prevent separation of the joint, but where a mortice and tenon is employed i.e. a fully enclosed joint then this would not be required. Tapered pegs driven into an offset (drilled) mortice and tenon joint do not pull up and sit at exactly 90 degrees but at a slight angle reflecting the degree of taper on the peg since tapered pegs pull up tight on one "face" of the peg only

Sometimes I've seen these trusses made w/ the king post tenon running long, protruding past the bottom of the tie beam and then wedged... kind of like an anchor beam (tie beam) found in old dutch barns.

My guess is 90-degree pegging is usually done because that's the easiest approach and facilitates draw-boring. It would be more difficult to draw-bore a joint w/ angled pegs.

I'm sorry?

Obviously there are helpful posts for this questions (see Ken Hume or ourbarns1). They responded with what they knew about the topic in as much as they felt was applicable. Then there is djswan?? Please refrain from your useless banter. "Nobody does it like me" is really old and obnoxious.

If the tie chord of the truss carries the load of the second floor loft, then the loading on the pegs could exceed the capacity of the pegs. Pegs that are in a constant pinch will suffer compression damage. Also the load on the rafter chords will increase with the addition of floor load on the truss system.

Trimber, Whats your thinking on pegging this arrangement as skewed angles?
