i plan on doing some work regarding a lower motorcycle fork tube, the question is with this ~18" tube mounted on a hf 9x20 properly (chucked in a way so chuck is not in the way), will i be able to have access to cut the whole piece, im wondering this becasue ive seen specs where the saddle has a total travel of about 16", basically what is the useable space of this hf 9x20
