I took a five foot section of 4 inch I.D. PVC and cut a slot down the entire length that was just large enough to allow the pipe to be snapped onto the mast. With just a little force the slot opens wide enough to slip onto the mast. This slotted pipe, intended to support the comptip and its joint, needed another smaller slot on the opposite side about 6 inches long to allow the pipe to slide beyond the mast tang. Now the PVC pipe relieves the stress to the comptip as it rests on the rear beam.
