I admit I am rubbish at making bows, but, the past four years tinkering with bow making has taught me that I can floor tiller almost anything to first brace by making sure the whole bow limb is bending correctly before even putting the string on. I dont even need to use a long string now, by making sure the whole limb is bending just right using floor tiller before you even reach for a tiller string was my eureka moment between all the crap bows I made and now the semi-crap bows I can make!
Training your eye through practice to floor tiller, makes the difference between someone who gets lucky now and again with making a half decent bow and someone who can consistently make good shooters, deffo a skill worth cultivating if you take your bow making serious.
