You cant have set the thing up properly, first you have to shim the bits that hold the revolving face,old postcards are good for this and take care not to drop the screws they run under the nearest fixed object and are imposable to find, now screw the thing down tight so the revolving face runns true about the center, you will now find that it is almost imposable to move due to the friction so lubricate it with french chalk or you favorate talc !
Good luck you will come to love the CPR 5 ....NOT.
