Kevin,
Just wanted to bump this thread and add some thoughts that I meant to send a while ago. I know you mentioned the miter saw station in the other note (nice miter saw model, btw), so I'm leaving that alone, although I will help build when the time comes.
On the dust collection, I have been putting some heavy miles on the thickness planer and light miles on the jointer in the last few weeks. It occurs to me that the fix you made to the dust chute on the planer to mate with the loose dust collection hose (the table saw one) is really effective (thanks!). So I wonder if it would be easier to make something in the same vein for the jointer. Something like the wooden box on there now but where the hose could be connected at the bottom. That's a much different solution than dedicated dust collection, but maybe just as good. The chute on the planer is also still being held on with duct tabpe (and maybe a handful of wood screws), so it might also be good to fabricate something more permanent but with the same functionality.
I'm guessing a dedicated cabinet will connect to the two machines in essentially that same way, although maybe with better suction from straighter hose? Anyway, it may still be worthwhile to build a new dust cabiet, but wanted to bring this back to the front burner. Again, let me know when you're thinking about doing a build day and I will join. Thanks for your effort on this!
Mike
