The guy who made the PVC deal was from this board. He used a Tee with the I.D. close to the dia. of the shaft, cut the run of the tee in half like a saddle. Then used a PVC base that was like 5in. in DIA. with threads in the center. He then put a piece between base and tee the lenght he needed.You need to make it about 1.5 In. longer to put upward pressure on the shaft to keep it from bouncing. You could make the whole thing for under 10 bucks. So get after it T MAN
