I am in process of starting a new chassisbuild. The blue prints for the chassis call for 6 inch radius bends using 1 5/8tubing . The bender I will be using has a 7inch radius. Does anyone know offhand if just adding to overall length of the tubing. Starting bends ½ inchsooner will obtain the proper finished result ? I also was thinking of maybere-drawing the print to scale to check design. Any thoughts ?

Thanks John
