I bought lining poles from lion country, but once I got them, i decided next time i would build them out of pvc. If you do build yours, use the design of lion country's safety lining poles. I have 3 of them; they are great (you can turn the point around for storage.).
re holding blinds, we just build our own. if you can weld, just use rebar and get some camo tarp. I will try my next one out of pvc.
I made mine out of 1.25" round wood stock. Drilled a 1/4" hole in one end about 4" deep, and filled with waterproof glue. Insert a spike about a foot long into the hole, tap the spike to set the point into the pole, and grind off the head of the spike.
I painted one side orange, and the other camo for multi use. Seems to work fine.
I have used pvc pipe with elbows and such which worked out fine. Breaks down real easy. For something simple, garden stakes with the camo material locked tied onto the garden stakes - hunted behind one many times and rolls up small.
I HAVE HAD/TRIED ALL OF THEM AND I NOW USE A SIMPLE 1X3 INCH OF PINE WHICH I CUT INTO DIFFERENT LENTHS (LONGER FOR DISTANCE) AND PAINT THEM ORANGE AND DRILL OUT THE BOTTOM AND GLUE A PEICE OF 1/4 INCH ROD INTO THE BOTTOM. YOU CAN TURN THE WOOD SO YOU CAN EITHER SEE ALL 3-4 INCHES OR TURN MORE TO SEE ONLY THE SIDE PROFILE. ANOTHER GOOD THING IS IF ONE OF YOUR TRAINING BUDDYS FORGET TO PICK IT UP YOU LOOSE ONLY A PIECE OF WOOD. TRUST ME THEY WORK GREAT)
