I want to make 40 to 50 PVC sap bag holders this off season and am going to use 3" Schedule 40 pipe so that they pour out easily. I have a couple of questions: 1) what length should I cut them to (at 5" long I can cut 24 pcs out of a 10' length of pipe); and 2) what is a good spile to use with the PVC bag holders? I have a miter box, drill press and table saw so I should have all the equipment to make them. Thanks, Clay
