I’m making my own blast gates for my new dust collection system. I’m debating an adhesive to join the plywood gate to the pvc pipe stubs that will be the connectors to the vacuum pipes. I’m debating between something like Liquid Nails vs. silicone caulk. These gates are made so they’ll be the support brackets for the pipes (on the wall as well as ceiling) as well as cut-offs. I wonder if you’ve done something similar and have recommendations. I got the basic design off of YouTube.
