hello all. here are link lengths Link 1=177.8, Link 2=228.6, Link 3=76.2, Link 4= 203.2 . I dont know how I can choose a convenient scale for these links.Do you have any idea? For example is it a good approch to choose 1 cm for 50 mm.to what centimeters can I roll the numbers. Link ratios to the shortest are such as 2.667 or 2.333.
