side gap between fence blade varies depending side pressure exerted cutting have solved problem crudely effectively clamping far end fence saw table once fence position solution crucial precision ripping Without pieces consistent width cannot made second problem fence its edge slightly radiused meets table causes problems cut ting thin gauges because material tends get caught move around gap problem can solved gluing strip si-in ply blade side fence Cutoff tray use tool other Its good making precise rec tangular pieces such shear webs bulkheads can notch ribs trailing edges basic concept
