while the bend for the tri stock is not gtreat I like to relieve the stress in the wood by preforming,this step os not really neccassary but it something that I like to do and does not take much time,it will be dry by the time I cut the lawn.both pieces of tri stock are soaked with hot water'put in the tub and tuen on the hot water for a few minutes,pin the sides to a stout wood block here a scrap of 2 by 6 is used then using the doubler as a form bin the outside edge starting at the nose and slowly bending around the doubler,pinning the outside edge to keep the stock tifgt against the doubler
