Pvc Pipe Trees On There Sides Work Pretty Good And They Dont Hang Up Your Jigs. Just Drill A 4 Or 5 Holes To Make Them In A Cross Pattern So That They Will Stand Up Off The Bottom. Put A 8" Block On A 3 Or 4 " Pipe With 3/4" Cross Pipes For Limbs. Slide The Block On Before You Put Your Cross Limbs Through And The Block Will Hold It Down.
