Reference Lines

Straight edges? – you can forget it.

Look along any length of timber in the yard which is ready to go into the workshop to be incorporated into a frame, and you will be hard pressed to find one which doesn’t have a twist or a bow of some kind.

Tension forms in the wood as the tree grows and this can result in “deflections” of up to 20mm over a 6m length.

So how do you account for these when framing if you can’t rely on a straight edge?

Reference lines are applied to the timbers with a chalk or ink line and form the basis for all square and level calculations. Extrapolating something plumb, level and square out of 20 tons of wonk is what makes timber framing such fun!
