Time restraints would prevent it in this case, but it's a good idea none the less. Are you sure the ACQ chems would interact with powder coat too?? Man i could see a huge market there for a established powder coating company that could run thousands of hangers a day in either green or brown (to match any future staining)
I dont know, I might just say the heck with it and notch beams/rails so it's done right even though it will take more time I'll know it's the way it should be. We dont have alot to do since it's only covering a 22' span and we're going 24"oc and home owner is going to drape a canvas type material over it for more shade and ashtetics so it's not like I have 100 cuts I have to worry about, we'll just set up the planks and run 'em

Was just hopin for a half day project on the arbor so I can move onto the porch project.
