Yeah I have a friend who uses one, literally got a load of scraps and cut offs from a dealer made the wooden frame with two threaded steal rods through and tightened with bolts and hey presto good to go, works well on his 60# hoyt compound,I notice some clubs are using compressed layers of foam carpet padding for target constrution. Has anybody tried this. ?? Some clubs in Florida say they are getting years of service out of this material.
