I have a Slick carbon fiber tripod and Jim White panning head with light weight ball head on top for my spotting scope. I also have a set shooting sticks for hunting. The other day I was looking at my gear and figured why am I carrying both of these. I should just make a v-block that will fit on top of my panning head and leave the ball head attached to the bottom of the spotting scope. So I threw this design together pretty quick and am getting ready to order the delrin to cut it out of. The weight is about 2.25 ounces and it will fully contact the top surface of the panning head when screwed on. Figure I will leave this on the tripod so incase I need it quick I can grap it. If I need to use the spotting scope I have time to unscrew it and screw on the spotting scope. This should eliminate the added weight of the shooting sticks. What do you guys think? Any suggestions while it is still on paper and before I program it into the mill?
