I recently bought a Stihl FS85RT Split Boom Trimmer and the articulating 0-90 hedge trimmer. My problem is the I would like to have a shorter shaft to use on the hedge trimmer than that long shaft that they supplied with the hedge trimmer. If you don't need the long shaft (not trimming high or wide) then you can't really use the hedge trimmer attachment. I guess I'm trying to make a HL75 hedge trimmer (http://www.stihlusa.com/trimmers/HL-75_90.html) out of a FS 85RT Slit Boom. Does any one else have any suggestions on how to come up with a 12" shaft to use?
