I have a bucket with several pins. Another with several rebar pins with 90 degree bends in top. If the pins are too sloppy, the rebar as a shim can snug it. Too easy to put three pieces of rebar in an eye, once it is all set. One rebar makes it nice and flexible for set up on uneven terrain. Go back and shim. Takes out all guess work. Paint the rebar white with orange tips on the 90. Makes it easy to find when one gets dropped.
Hate the store bought pins with just a crimp on the end. Thru the years I have gathered a lot of short pipe. Weld a flat bar T on the end. No stuck pin. Those tiny pieces of flat bar scrap or angle pieces are great for pin caps. Spot weld them onto a one foot piece of pipe and drop them in the pin bucket.
