I have Dave Lennards' old tiger pole. The hoop sleeves into the main pole and the attachment end sleeves on as well. He even sent a sleeved on replacement for the hoop so the pole can be used for deck launching instead of snuffing. So, the pole is really 3 pieces. I broke the center section which is 8'6" long. Both sleeve pieces were loose fitted and had been taped to prevent any slop. The extrusion I just received is approx 2/1000ths too small inside. The sleeves are roughly 18", so they do extend quite a ways inside the center section. I'm concerned that if I mill either piece it won't be strong enough. Would it be best to mill the inserts or the replacement tube?
