I rushed up to the workshop and found the fan heater still circulating warm air at 36 degrees and when I measured the tenons on the rungs, which were put in the dryer 14 hours earlier, they had shrunk from 5/8″ (15.9mm) diameter to a beautiful oval, 14.3 x 15.3mm – maybe not earth shattering to most people but for me, it a technological triumph – thanks John!! In a few days, these will be squeezed into 14mm holes.
Also pictured are the 5 spindles with tenons made to 3/8″. Tomorrow we’ll use a 5/16″ tenon cutter to fit them into 8mm holes. Who says my 3rd class degree in Maths was a waste of time?
