hey Jerry,
it sounds to me like you got it covered. and im glad to see youre router is like mine , not inside a cabinet.
i think youre shop looks great and i had no intentions to sound negative. you have done a great job!
i am just glad my shop is a place that i can use without worrying about dust. see im lazy by nature and dont like cleaning ,lol!
honestly, your shop looks great and after a few months when you say i will repaint and the heck with the dust, you will really enjoy it, lol!
i think the air filter will help with the small stuff, but think you may need a dc to make a big difference. thats my opinion and with my little woodworking experience know i might be wrong.
anyway dont worry about anything i say, im just learning
light travels faster than sound, this is why some people seem bright til you hear them speak.
