I have a Bogen 3033 tripod with a 3047 head. Had it for decades and while it is as strong as ever I ain't. I want to remove the 3047 head to save weight but can't figure how to get if off. There are 3 grub screws on the bottom of the head plate, I thought loosening those would allow me to un-screw the head. Didn't work.
Any suggestions welcomed.
