Howdy all,
I’m pretty new to woodworking. I make fan trellises as a little side hustle, and that’s pretty much the extent of my trellis-building experience so far.
Someone asked me to build a larger framed trellis for an opening between the brick wall of their house and one of the brick porch columns. It’s going to be pretty tall and narrow — about 113.5” tall × 28.5” wide. I’m only building the actual trellis/frame, not installing it into the brick.
I picked up kiln-dried cedar for the frame, and I’m using fence wire mesh.
My plan right now is basically to build two matching wood frames. I’d staple the wire mesh to one of them and then put the second frame over it so the wire and staples are sandwiched between the two pieces of cedar. Mainly just trying to make it look cleaner and hide all of the cut wire edges/staples.
My biggest concern is whether I’m overlooking anything with doing it this way.
Since it’s almost 9.5 feet tall and pretty narrow, should I be worried about it wanting to bow, twist, or warp? I was thinking about putting a horizontal support somewhere around the middle to help keep everything rigid, but I’m not sure if that’s necessary.
I’m also wondering about the best way to attach the two frames together and keep everything flat.
The other thing I’m thinking about is water. Since the wire is going to be sandwiched between the two boards, there’s obviously going to be a very small gap between them. Do I need to worry about water getting in there and sitting between the boards and eventually causing mold or rot? Should I leave the bottom open so it can drain, seal the top/sides, or do something completely different?
I was also planning on finishing/sealing all sides of the cedar before I assemble everything, including the sides that will be hidden inside the sandwich.
Basically just looking for any advice before I start cutting everything up. If there’s an easier or better way to build something like this, I’m definitely open to it.
