Recently, I damaged my tuba's Piston casing/cylinders while transporting the instrument.  As a result, all pistons are stuck.  I can't see any visible damages on the casings, so they may just be slightly out of shape.  I can still take the individual pistons out.  Any chances of self repair here?  I am short of money at the moment and there is a gig coming up.  Is there a special tool to help?  I am desperate for any advice.
Thanks
Danny
