does the build quality remind you of a handgun? i swear it can transform into a glock lol.
if the vice is tight its probably your tubes.i was just talking about this with one of my friends last week. chinese tubes are not made to the same specs as american say a Dringenberg tube. this machine is probably built to fit those types of tubes just like how a Aaron Cain, Seth C and allot of quality builders tube vices will all seem too small if your using cheaper tubes.quality machines are built to work with quality tubes.i bought about 15 kingpin tubes and had to file out a couple of my tube vices to fit them..that sucked
