Went to Lowes and purchased an adjustable pipe cutter. Marked the stabilizer length for keeping the baffle vertical and cut off the excess pipe. Very easy to do after seeing a plumber do it awhile back with that style tool. The pipes, shot and tools cost about $85, so less than $43/stabilizer. Could have used a 1"x2"x8' piece of oak, but I like this look better.
Next add the lead shot to the pipe, seal and flatten the other end for mounting hole drilling.
