This feels like one of the dumbest problems. Trying to make DIY tips, bought frame from Home Depot, screen from BRS-black 1/4”. I have tried 3 spline sizes .14, .16, .175 all seem to be lifting out of the track almost as soon as I put it in. Seems like the mesh is so stiff it is pushing the spline out. When I try to use the tool to form the mesh in the track first I have to push so hard it almost breaks the mesh. Only other idea at this point is to lay the mesh out in the sun to hopefully make it more pliable so it forms into the channel. Didn’t see any other threads talking about this, anyone else struggle with what seems like a stupid simple project?
