For the skyscreen rods, go to your local Panda Express and get the wooden chopsticks. Separate them and place them back to back and take a 3rd one and place it 1/2 way between the other 2. Super glue the 3 together so the 3rd acts as reinforcement to the other 2. The length is a perfect replacement for my Chrony Beta Master and the tapered ends fit in both the Chrony body and the sky screen hole. This way, when you shoot the sky screen rod, you won't bust the plastic insert to the chronograph. Sometimes it could be an errant muzzleloader sabot or a shotgun wad so it's not just the bullet that can hit the rod. Panda Express must know that we are using their chopsticks for things like skyscreen rods and lead casting pot stirrers because now you have to ask for them at the counter instead of leaving a pile of them with the forks and cup lids. No matter, I ask for one set at each visit and build up a stockpile that way.
