I made these rod holders a few months ago for my pontoon. I got the idea from the BOC library. I just made a few adjustments to fit my boat. They work EXCELLENT! For all the supplies I payed approx 28 dollars including tax....there is no drilling all at all. The pipe stay attached with radiator hose clamps. All I have to do is tighten them down when I get ready to use them and put the "Y" connectors on for the rods to sit in (they blow out when I drive to and from the river if I leave them on). All the parts except the "Y" connectors are glued with PVC pipe glue. They "y" connectors can rotate 360 degrees since I dont glue them. Both peices took me less than an hour to make and the only tool I needed was a hack saw. You can use sand paper to smooth out the edges but I just scraped them on the ground and it worked fine:smile2:.
