I wasn’t a member when the rules regarding 2x4s, southern yellow pine, pressure treated lumber, and reclaimed wood were put in place, but I can understand why they are/were there. There is no reason to run cheap 2x4s through the jointer or planer. If you need true flat and square wood, you should buy better wood. And I’ve used southern yellow pine for years, but only ripped from 2x12s that I’ve carefully picked out that weren’t too sappy or wet, and I only used my table saw or chop saw (and perhaps the bandsaw) on them. I would never run that kind of wood through a jointer or planer, because it gums up blades on the machines, and can actually rip the teeth out of the jointer. Pressure treated lumber shouldn’t be cut with anything other than a chop saw (not the Festool) or a cheap jobsite table saw and not ANY of the Woodshop tools. Reclaimed lumber should only be used with great caution. It has to be free of dirt and debris and free of any kind of metal.
Having said this, I realize that not everyone at DMS makes fine furniture. Some just need the use of a chop saw, or table saw, then go on about their business. They need access to contractor grade tools and really nothing more. The problem is that is not what we have in the Woodshop. We have some very expensive, professional quality equipment in the shop.
Both arguments are valid. DMS members need easier access to most of the Woodshop tools. And the Woodshop needs to be able to own nice things without having them broken through misuse or abuse. The challenge going forward will be in finding the proper balance.
