Substitute for Bicep Workout Burn Set?

okay i've basically just started a new work out routine. I go to the gym so i have access to nearly all normal equipment apart from (annoyingly) cables for bicep preacher curls. Cables are needed for the burn set of the bicep part of my workout routine. Does anyone know a different workout that can be used instead of cable preacher curls for a burn set of about 40 for the work out. I'm already doing barbell curls, pinwheel curls and concentrated seated bicep curls if that help.. cheers for any advice people
