You can make a simple tillering stand with a pulley in 15 min. Use a 2x4 about 4 feet plus long, if you have some scrap 1/2" plywood, nail an 18' square of it to the bottom. Buy a simple single steel pulley at the harware store for a couple bucks with space to run a 3/8" rope through it, one with any eye screw and screw it into the base at the base of the 2x4. Tack a couple of pieces of 3/6" plywood or something about 3x4" in size at the top of the 2x4 to hold the bow. Get a six foot length of 3/8 nylong rope through the pulley and attach end to an inexpensive steel hook. Use a sharpie and a yard stick and mark off you inch scale downward from the top of the 2x4. Yoiu can attach a hanging scale to the rope at the right time. Can get one on ebay for $20.
Wala.
