Bad Ducts

My biggest chip producer is at the end of the dust collection duct work, wasn't planned that way because it wasn't planned. It just grew topsie turvey as machines were added or changed and the shop is so small there is not much chance to make it right. Long way around to; as I dimensioned the Sapele for the little display case this morning the planer started spitting chips back at me. It's a pretty good sign the dust collection system isn't working and sure enough it was totally plugged. I started removing duct work until I could find some suction, the good news is there was pretty good suction just before the jointer "Y" which is the next machine over from the planer. As expected there was a hole in the jointer's duct. While I'm working on the system I'm going to reinstall the blast gates at each machine....A PITA to keep up with opening and closing but I expect it will be worthwhile with the planer now at the end of the line.
