Podgers or framing pins are tapered steel pins that mimic the form and job of an oak peg.
“Podgers!” is the confusing cry that can often be heard on raising day.

Friday afternoon musings about timber framing – ‘The Jowl Post’
Perhaps not the most glamorous of workshop tools you might think, but probably the most important. With carpentry it’s imperative to draw an accurate line that you can cut to.
The quest for the ideal pencil can consume a timber framer to the point of obsession! All too rarely the individual properties of wood and lead combine in such a way that leaves a perfectly clear sharp line ready for machining.
The relationship between timber framer and pencil can be profound and yet fleeting as by the time you’ve discovered the “chosen one”, it’s been whittled away into an inch long stub – you’ll see I can’t bear to throw mine away…….fag ends in an ash tray.
Draw Pegging is a nifty (and of course historic) way of getting timber frame joints to close up snugly under tension.
It’s achieved by offsetting the peg hole in the tenon relative to the peg hole in the mortice by about 4mm closer to the shoulder.
When the joint is assembled, the tapered oak peg tries to align the 2 holes and literally goes round the (very slight) bend, tightening the joint.
The “offset pricker” (yes, that’s what we call it) is a handy tool with an offset centre used to mark the tenons. Get it the wrong way round and you’ll find that your oak pegs prise open the joints like a squirrel in a sack of hazelnuts.

The Queen Post Truss
A truss is effectively a large triangle that serves to support the roof and stop the building from spreading.The queen post truss is perhaps the most common roof truss and consists of a pair of principal rafters jointed at the apex with a bridal joint and tenoned into a tie beam at the bottom.
Queen posts, are added to stiffen the truss and stop the principal rafters from flexing. Queen posts are often curved, but may be straight to frame a window in a gable for example.Jowl Post. Sin Comentarios
Timber frame musings – ‘The Jowl Post’
Sartorially designed to stop your trousers from falling down, braces have an even more important job to do when considering and designing a timber frame. Without them the vertical elements of the frame would topple like dominoes around your ankles when subjected to wind loads.
Diagonal bracing creates a strong triangle and when braces are incorporated into a frame in opposing tabs pairs, they help to counter the evil forces of “racking”.
We use curved timbers for braces – why? Because they look good and it’s a tip of the hat to tradition when poorer grade bent timbers may have been used to avoid waste.Mar-01-13 a las 12:23 pm Jowl Post. Sin Comentarios
If you're considering an oak framed building (or larch, or douglas fir), let's talk. We'll gladly put together an outline quote (completely free, with no strings attached). And we need very little information from you to do so.
Equally, we're always here, at the end of the phone, to talk through your ideas.
